Abstract: In a power transmission apparatus, an auxiliary clutch plate different in diameter from driving and driven clutch plates located in a clutch housing. When the driving and driven clutch plates are pressed against each other, the auxiliary clutch plate is pressed to enable transmission of a driving force of an engine to a driving wheel. When a pressing force exerted on the driving and driven clutch plates is released, a pressing force exerted on the auxiliary clutch plate is released to cut off transmission of the driving force of the engine to the driving wheel.

Abstract: Provided are a wet friction plate and a wet multiplate clutch device capable of reduction drag torque while suppressing a decrease in the area of a friction member. The wet friction plate includes multiple friction members through oil grooves on a flat plate annular core metal. The friction member has first fine grooves opening at an inner peripheral edge of the friction member and extending to an outer peripheral edge side and second fine grooves opening at an outer peripheral edge of the friction member and extending to an inner peripheral edge side. The first fine groove and the second fine groove are formed to have a groove width of equal to or greater than 0.1 mm and equal to or less than 0.8 mm, and overlap portions overlapping with each other in a circumferential direction at the same position in a radial direction of the core metal.

Abstract: A torque damper apparatus includes an input-side plate having a pair of side plates and rotatably driven in response to drive force from a motor, a center plate coupled to an output shaft and arranged between the pair of side plates, and an elastic transmission body provided between the input-side plate and the center plate to transmit rotary drive force of the input-side plate to the center plate. The input-side plate has, at a plate surface of at least one side plate, multiple weight attachment holes for attaching a balance weight. Each weight attachment hole is formed in a long hole shape extending along a circumferential direction at an outer edge portion of the side plate.

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: A molding apparatus for obtaining an annular molded article has a fixed die D1 and a movable die D2 capable of forming an annular cavity C. A first block B1 and a second block B2 are formed inside the cavity C in the fixed and movable dies D1 and D2. The blocks form a flow channel R communicating with the cavity C. Thus, gas generated in the cavity C and a molten metal can flow in the flow channel R. A discharge hole B2b is formed in the second block B2 to discharge the gas flowing in the flow channel R to the outside. A forming surface of the flow channel R, in the first and second blocks B1 and B2, is formed in an outer circumferential shape following an inner circumferential shape of the cavity C.

Abstract: A power transmission device has a first clutch member 4a coupled to an output member 3. A second clutch member 4b has a plurality of driven-side clutch plates 7. A back-torque transmitting cam presses the 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. A cushioning member 12 is interposed between the first clutch member 4a and the second clutch member 4b. The cushioning member 12, by being compressed, applies an urging force while allowing movements of an interlocking member 9 and a pressure member 5 in a process where the interlocking member 9 moves and the pressure member 5 moves from the inactive position toward the active position.

Abstract: Provided are a wet friction plate and a wet multiplate clutch device capable of reduction drag torque while suppressing a decrease in the area of a friction member. A wet multiplate clutch device 100 includes wet friction plates 110 at positions facing clutch plates 103 rotatably driven by rotary drive force of an engine. The wet friction plate 110 includes multiple friction members 112 through oil grooves 115 on a flat plate annular core metal 111. The friction member 112 has first fine grooves 113 opening at an inner peripheral edge 112a of the friction member 112 and extending to an outer peripheral edge side 112b and second fine grooves 114 opening at an outer peripheral edge 112b of the friction member 112 and extending to an inner peripheral edge side 112a. The first fine groove 113 and the second fine groove 114 are formed to have a groove width of equal to or greater than 0.1 mm and equal to or less than 0.8 mm, and overlap portions 113c, 114c overlapping with each other in a circumferential direction at the same position in a radial direction of the core metal.

Abstract: A fuel cell system has a cell (1) that is capable of generating electric power. The cell (1) has a fuel electrode (1a), an air electrode (1b) and an electrolyte (1c). The fuel electrode (1a) is supplied with hydrogen obtained by reforming fuel gas. The air electrode (1b) is supplied with oxygen in the air. The electrolyte (1c) is interposed between the fuel electrode (1a) and the air electrode (1b) to enable oxygen ions to pass through to the fuel electrode (1a). A water vapor retaining mechanism (6) is disposed in a flow path of the fuel gas supplied to the fuel electrode (1a). The mechanism (6) retains water vapor generated in the fuel electrode (1a) during electric power generation by the cell (1). The mechanism (6) enables the water vapor to be mixed with the fuel gas.
