Abstract: A hybrid vehicle transmission includes a first input shaft, a second input shaft, an output shaft, a plurality of input gears, a plurality of output gears and an input shaft coupling unit. The plurality of input gears are provided corresponding to a plurality of gear stages, and are each supported by the first input shaft or the second input shaft. The plurality of output gears are provided corresponding to the plurality of gear stages, and are supported by the output shaft. The input shaft coupling unit is configured to couple the first input shaft and the second input shaft while being capable of decoupling the first input shaft and the second input shaft.

Abstract: A dynamic damper device for inhibiting torque fluctuations in a rotor to which a torque is inputted includes a mass body and a magnetic damper mechanism. The mass body is disposed to be rotatable with the rotor and be rotatable relatively to the rotor. The magnetic damper mechanism includes at least a pair of magnets disposed in the rotor and the mass body. The magnetic damper mechanism couples the rotor and the mass body in a rotational direction by a magnetism of the pair of magnets.

Abstract: A rotary electric machine includes a rotary shaft, a rotor provided on the rotary shaft, a stator and a housing. The stator includes a stator core, which is disposed on an outer periphery of the rotor, and a coil that is wound about the stator core and includes end coils exposed from the stator core in directions oriented along an axial direction of the rotary shaft. The housing, by which the rotary shaft is rotatably supported, accommodates the rotor and the stator in the interior thereof, and is provided with a housing flow pathway on an inner wall surface thereof. The housing flow pathway is serial and causes a liquid coolant for cooling an outer periphery of the stator core and the end coils to flow therethrough.

Abstract: It is an object of the present invention to provide a compact torque transmission device. The torque transmission device includes an input-side member, an output-side member, a clutch and a pressing mechanism. The clutch is configured to transmit or cut torque between the input-side member and the output-side member. The pressing mechanism includes a pressing member for pressing the clutch, and a pressing device. The pressing device is a device for pressing the pressing member, and is disposed on the inner peripheral side of the clutch.
