摘要： A clutch device includes a clutch center (40) and a pressure plate (70) operable to move toward or away from the clutch center and rotatable relative to the clutch center. The pressure plate includes a pressure-side cam portion (90). The clutch center includes a center-side cam portion (60). The pressure plate includes a boss (84) extending in movement directions. The clutch center includes a through hole (54H) in which a boss (84) is insertable. The through hole extends along circumferential directions and allows movement of the boss along the circumferential directions and the movement directions. While a surface of the pressure-side cam portion and a surface of the center-side cam portion are in contact with each other, a distal end of the boss projects outward from the through hole.

摘要： A clutch device (10) includes a pressure plate (70) movable toward or away from a clutch center (40), rotatable relative to the clutch center, and operable to press input-side rotating plates and output-side rotating plates. The clutch center includes an oil passage (41), at least a portion of which is located in an inner peripheral surface of an outer peripheral wall to guide clutch oil to a center-side fitting portion (88). The pressure plate includes a pressure-side recess (71) on an outer peripheral surface of a pressure-side fitting portion (88), recessed radially inward from the outer peripheral surface over the entire outer peripheral surface in movement directions, and continuous with the pressure-side cam hole (73H) when seen in movement directions. The pressure-side recess (71) communicates with the oil passage (41).

摘要： Provided is a power transmission device that can suppress feeling of surprise when power is transmitted and can improve operability while efficiently utilizing a space that is obtained by the arrangement of a first clutch member and a second clutch member. The power transmission device include: a first clutch member 4a that is coupled to an output member 3; a second clutch member 4b to which driven-side clutch plates 7 are attached; a back-torque transmitting cam that is capable of pressing drive-side clutch plates 6 and the driven-side clutch plates 7 against each other by moving the second clutch member 4b when a rotational force is input to the first clutch member 4a; and a cushioning member 12 that is interposed between the first clutch member 4a and the second clutch member 4b and that is capable of applying an urging force while allowing movements of an interlocking member 9 and a pressure member 5 by being compressed in a process in which the interlocking member 9 moves and the pressure member 5 moves from the inactive position toward the active position.

摘要： Provided are a wet friction plate and a wet multiplate clutch device including the wet friction plates capable of improving the performance for discharging lubricant oil adhering to surfaces of friction members. A wet friction plate 200 includes oil grooves 203 and friction members 210 on a flat plate annular core metal 201. At a surface of a porous layer 211 of the friction member 210, a friction slide surface 213 and lubricant oil recessed portions 214 are formed. The lubricant oil recessed portion 214 has no sharp portion in a pointed shape, such as a corner portion, and is formed with a smooth continuous surface. The multiple lubricant oil recessed portions 214 depressed in a recessed shape with respect to the friction slide surface 213 are formed. In the porous layer 211, hollow portions 212 are formed to have the same formation rate between a portion forming the friction slide surface 213 and a portion forming the lubricant oil recessed portion 214.

摘要： Provided is a fuel cell system which has a simple structure and with which water vapor for reforming can be obtained efficiently. The fuel cell system includes a cell 1 that is capable of generating electric power and includes: a fuel electrode 1a to which hydrogen obtained by reforming fuel gas is supplied; an air electrode 1b to which oxygen in air is supplied; and an electrolyte 1c interposed between the fuel electrode 1a and the air electrode 1b and allowing oxygen ions generated from oxygen in the air supplied to the air electrode to pass through to the fuel electrode. The fuel cell system further includes a water vapor retaining means 6 that is disposed in a flow path of the fuel gas to be supplied to the fuel electrode 1a, retains water vapor generated in the fuel electrode 1a during electric power generation by the cell 1, and allows the water vapor to be mixed with the fuel gas.

摘要： Provided is a power transmission device that can improve responsiveness when engaging a clutch and improve operability by reducing the sliding resistance of a receiving member. The power transmission device includes: a pressure member 5 that is capable pressing drive-side clutch plates and driven-side clutch plates against each other or releasing a press-contact force; a clutch spring 10 that urges the pressure member in a direction such that the clutch plates are pressed against each other; a receiving member 11 that is constituted by a separate member attached to the pressure member 5; and a back-torque limiting cam that reduces the press-contact force between the clutch plates when the rotation speed of an output member exceeds the rotation speed of an input member. The power transmission device includes a radially-outside restricting portion that is capable of restricting radially-outward movement of the receiving member 11 relative to the pressure member 5 and is capable of maintaining a clearance t between a side surface 11d of the receiving member 11 and an inner peripheral wall 4e of a clutch member 4.

摘要： An aluminum component and a method for manufacturing the aluminum component with which the occurrence of chipping of splines can be reduced are provided. A method for manufacturing an aluminum component includes a forming step of obtaining an aluminum casting having projections f that extend in an axial direction and that are continuously arranged in a circumferential direction, and a cutting step of cutting projecting end portions of the projections f formed in the forming step along a processing line having a predetermined processing diameter D, thereby obtaining splines S of predetermined dimensions. Each projection f is formed such that side surfaces fa thereof are inclined to be tapered in a direction from a base end to a projecting end, and such that a portion of each side surface fa that is adjacent to the projecting end and that is cut in the cutting step is an inclined surface fb having an inclination angle less than an inclination angle of a portion of the side surface that is adjacent to the base end.

摘要： There is provided a power transmission device that can apply engine brake by transmitting a rotational force on the side of a wheel to the side of an engine by bringing driving clutch plates and driven clutch plates into press contact with each other when a pressure member is located at a non-actuation position, and that can make actuation using a weight member stable when engine brake is applied. The power transmission device has a back torque transmission cam that can bring the driving clutch plates 6 and the driven clutch plates 7 into press contact with each other by moving the second clutch member 4b when a rotational force is input to the first clutch member 4a via the output shaft 3 when the pressure member 5 is located at the non-actuation position. The back torque transmission cam can hold abutment between the interlocking member 9 and the weight member 8 by moving the second clutch member 4b in a direction of being brought into proximity to the interlocking member 9.
