摘要： A power transmission structure of a vehicle, which is provided with a first rotor, a second rotor, and a metallic cylinder. In this power transmission structure, the reduction shaft and the second rotor shaft receive reaction force from the cylindrical metallic member in radially opposite directions. The cylindrical metallic member is deformable elastically in a radial direction and press-fitted in a part where the reduction shaft and the second rotor shaft of a second electric motor overlap each other in the radial direction adjacent to a spline fitting part of the reduction shaft and the second rotor shaft. Therefore, misalignment between the axis of the reduction shaft and the axis of the second rotor shaft is restrained, and generation of tooth hitting sound is thus restrained. Since the cylindrical metallic member has high rigidity and is restrained from being deformed in a rotation direction, responsiveness of torque transmission is improved.

摘要： A power transmission device includes a rotor shaft, a gear shaft, and a rattling suppression member. The rattling suppression member is provided between a first shaft end portion and the gear shaft or between a second shaft end portion and the rotor shaft. The first shaft end portion is a portion, protruding to the gear shaft side from one of a pair of first bearings, of the rotor shaft, while the second shaft end portion is a portion, protruding to the rotor shaft side from one of a pair of second bearings, of the gear shaft.

摘要： In a catch tank, a partition wall is formed that extends along a vehicle front-rear direction and divides the catch tank in a vehicle width direction in a vehicle-mounted state, which helps prevent oil in the catch tank from flowing unevenly to one of a first space and a second space even when the oil surface of the oil tilts during turn of the vehicle, for example. As a result, an appropriate amount of oil required for lubrication is supplied through a second lubrication hole regardless of tilt of the vehicle or turn of the vehicle.

摘要： A power transmission device may include a casing; and a plurality of gears located in the casing and being lubricated by a lubricant in the casing, wherein the plurality of gears may include a first gear that upwardly displaces the lubricant accumulating at a lower portion in the casing by rotation of the first gear; the casing may include a facing wall facing a side surface of the first gear; the facing wall may include a first rib that protrudes toward the side surface of the first gear and extends along a circumferential direction of the first gear; and the side surface of the first gear, the first rib, and the facing wall may define a first lubricant passage that guides the lubricant displaced upward by the first gear along the circumferential direction.

摘要： A shaft coupling structure includes a shaft, a sleeve, into which the shaft is inserted, and a tolerance ring. The tolerance ring includes a cylindrical main body and a plurality of protuberances, which protrudes outward in a radial direction from an inner circumferential surface of the main body. The tolerance ring is fitted between an outer circumferential surface of the shaft and an inner circumferential surface of the sleeve. A communication passage that connects an inside and an outside of each protuberance is provided between the outer circumferential surface of the shaft and the main body.
