A unit includes a heat exchanger; a motor case configured to accommodate a motor; and an inverter case configured to accommodate an inverter, wherein the inverter case has a portion that overlaps the heat exchanger and the motor case when viewed in a predetermined direction.

Motor case combination unit

Provided is a unit including: a housing configured to accommodate a differential gear mechanism, in which the housing has a flow path through which a coolant flows, the flow path has a portion that overlaps the differential gear mechanism when viewed in a radial direction, and the flow path has a portion that is positioned above a horizontal plane passing through an axis of an output shaft of the differential gear mechanism and orthogonal to a gravity direction.

Unit

An automatic transmission for an electric vehicle includes: a belt type continuously variable transmission mechanism; a constantly meshed parallel shaft type gear transmission mechanism which is connected to an output portion of the belt type continuously variable transmission mechanism, and which has a plurality of shift stages; an input gear which is disposed to the input shaft to be rotated relative to the input shaft, and which is drivingly connected to one of a plurality of shift gears fixed to an output side shaft of the constantly meshed parallel shaft type gear transmission mechanism; and an engaging clutch mechanism which is disposed to the input shaft, and which selectively connects one of the input portion of the belt type continuously variable transmission mechanism and the input gear to the main electric motor.

Automatic transmission for electric vehicle

A torque cam device includes: a drive cam member; a driven cam member; and an intermediate cam member which includes a second drive cam surface that is formed on one end, and that is arranged to be abutted on the first drive cam surface, a second driven cam surface that is formed on the other end, and that is arranged to be abutted on the first driven cam surface, and which is arranged to be rotated relative to the driven cam member and the driven cam member, the first and second drive cam surfaces being abutted on each other when a power is transmitted from the drive cam member to the driven cam member, the first and second driven cam surfaces being abutted on each other when the power is transmitted from the driven cam member to the drive cam member.
