A transmission includes: a case configured to store oil; a gear power transmission mechanism supported by the case and configured to operate in a state where a part of the gear power transmission mechanism is immersed in the oil stored in the case; a chain power transmission mechanism supported by the case; and a transmission mechanism supported by the case. The case includes a rib configured to cover the chain power transmission mechanism at an upper side of the chain power transmission mechanism in a vertical direction. The rib internally includes an oil passage for supplying oil to the transmission mechanism.

Transmission

A device includes a case; a first rotating body that has at least a part immersed in the oil in an oil bath; a second rotating body disposed in the case at a position not immersed in the oil in the oil bath; a plate; a first wall portion provided on the plate between the first rotating body and the second rotating body; a second wall portion provided above the first wall portion in a gravity direction and extending toward a direction away from the first rotating body; and a fourth wall portion provided between the first rotating body and the second rotating body and extending in a vertical direction on the plate, wherein the first wall portion is provided on a first rotating body side of the plate, and the fourth wall portion is provided on a second rotating body side of the plate.

Transmission including a baffle plate

A control device for a vehicle, the vehicle including a belt continuously variable transmission including a mechanical oil pump driven by an engine and an electric oil pump driven by an electric motor, the engine being configured to drive a drive wheel, in which when a rotation speed of the engine is less than or equal to a prescribed rotation speed as the vehicle decelerates, driving of the electric motor is controlled to supply a hydraulic pressure from the electric oil pump to the belt continuously variable transmission, and when the deceleration of the vehicle exceeds a prescribed deceleration, the driving of the electric motor is restricted not to supply the hydraulic pressure from the electric oil pump to the belt continuously variable transmission.
