Abstract: A method of forming a setter for firing a ceramic has a sheet formation step (S1 to S3) to form a structure by sheet formation. The structure has a porous layer S1 with ceramic fibers. A shaping step S5 shapes the structure, into a predetermined shape. A coating step S6 impregnates the predetermined shape structure, with an impregnation liquid to form a dense layer S2 on the outer surface of the porous layer S1. The dense layer S2 is denser than the porous layer S1. A firing step S7, fires, at a predetermined temperature, the structure that has been subjected to the coating step S6.

Abstract: A progressive press metal mold has a lower mold 1, with a die having a plurality of die holes Da, and an upper mold 2, with punches P corresponding to the respective die holes Da, where the punches P and the corresponding die holes Da form a plurality of processing stages S. A belt-shaped metal material W is transported sequentially to perform predetermined pressing on the belt-shaped metal material W with the punches P and the die holes Da in the respective processing stages S. Electromagnets 7 are configured to attract, by magnetic force, the belt-shaped metal material W to be transported to the specific processing stage Sc.

Abstract: A clutch device includes a clutch center, and a pressure plate movable toward or away from the clutch center, rotatable relative to the clutch center, and operable to press input-side rotating plates and output-side rotating plates. The pressure plate holds the output-side rotating plates and includes pressure-side fitting teeth projecting radially outward from an outer peripheral surface of an outer peripheral wall and arranged in circumferential directions, and an oil channel in an end portion of at least one of the pressure-side fitting teeth in a first direction. The oil channel allows clutch oil flowing at least at an inner peripheral surface of the outer peripheral wall to be discharged to the outside of the pressure plate.

Abstract: A clutch device includes a clutch center including center-side fitting teeth, and a pressure plate including pressure-side fitting teeth. When a center-side assist cam surface and a pressure-side assist cam surface contact each other, an end of each of the pressure-side fitting teeth in a first direction is located ahead, in the first direction, of an end of a corresponding one of the center-side fitting teeth in a second direction, and at least portions of some of the pressure-side fitting teeth overlap with the center-side fitting teeth when seen in radial directions of the output shaft, and at least portions of others of the pressure-side fitting teeth do not overlap with the center-side fitting teeth when seen in radial directions of the output shaft.

Abstract: A clutch device includes a clutch center holding output-side rotating plates alternately arranged with input-side rotating plates, and a pressure plate movable toward or away from the clutch center. The pressure plate includes pressure-side fitting teeth holding the output-side rotating plates. The clutch center includes center-side fitting teeth holding the output-side rotating plates. In a half-clutch state, a portion of one of the center-side fitting teeth overlap with a portion of one of the pressure-side fitting teeth when seen in the radial directions of an output shaft.

Abstract: A vehicle platform includes a first wheel, a second wheel, and a first orientation keeper to move the first wheel in a vehicle width direction and keep an orientation of the first wheel with respect to a front-rear direction of a vehicle during movement of the first wheel. The first orientation keeper includes a first center body, a first wheel arm, and a first rotation actuator. The first center body is between the first wheel and the second wheel. The first wheel arm is rotatably connected to the first center body, extends between the first center body and the first wheel, and supports the first wheel. The first rotation actuator is operable to rotate the first wheel arm relative to the first center body such that the first wheel moves toward or away from the first center body.

Abstract: A power transmission device has an interlocking member 9 moving a pressure member 5 from an inactive position to an active position. A release spring (m) applies an urging force, while allowing movements of the interlocking member 9 and the pressure member 5, until drive-side clutch plates 6 and driven-side clutch plates 7 reach an engaged state before the drive-side clutch plates 6 and the driven-side clutch plates 7 are pressed against each other. A clutch spring 11 is compressed in a process where the interlocking member 9 moves after the drive-side clutch plates 6 and the driven-side clutch plates 7 have reached the engaged state. The clutch spring applying a press-contact force between the drive-side clutch plates 6 and the driven-side clutch plates 7 while allowing movements of the interlocking member 9 and the pressure member 5. The set load of the clutch spring 11 is set to be smaller than the maximum load of the release spring (m).

Abstract: 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 includes oil grooves and friction members on a flat plate annular core metal. At a surface of a porous layer of the friction member, a friction slide surface and lubricant oil recessed portions are formed. The lubricant oil recessed portion 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 depressed in a recessed shape with respect to the friction slide surface are formed. In the porous layer, hollow portions are formed to have the same formation rate between a portion forming the friction slide surface and a portion forming the lubricant oil recessed portion.
