To a side surface of the rotor on a pump side is formed with a tubular unit which extends towards the pump side, and an oil reservoir unit which accumulates a lubricating oil discharged from the pump is provided to an inner peripheral surface of the tubular unit. To the oil reservoir unit, a communicating hole which communicates the oil reservoir unit and a side surface of the rotor on a planetary gear mechanism side, is formed. The lubricating oil flowing from the oil reservoir unit via the communicating hole is guided to a carrier of the planetary gear mechanism.

Lubricating structure of transmission

A synchronizer for a transmission includes a shift rail, a first sleeve, a second sleeve, and a stopper. The shift rail includes a first shift fork and a second shift fork that are provided integrally with each other. The first sleeve is movable in a first direction along an axial direction from a predetermined first standby position to synchronize a first gear with a rotating shaft. The second sleeve is movable in a second direction along the axial direction from a predetermined second standby position to synchronize a second gear with the rotating shaft. A distance between the second sleeve at the predetermined second standby position and the stopper in the axial direction is smaller than a distance between the first sleeve at the predetermined first standby position and the third gear in the axial direction.

Synchronizer for transmission

A bearing locking mechanism capable of surely preventing dropping of a bearing, without increasing size of a transmission, is provided. In a bearing locking mechanism in which a bearing Gof a rotating body Gaxially supported by a transmission caserotationally is prevented from dropping from the transmission case, a transmissionis equipped with a brake Bprovided so as to be adjacent to the bearing G, the brake Bis equipped with a fixing member Bto be fixed to the transmission case, and the bearing Gis prevented from dropping from the transmission caseby the fixing member Bengaging with a side surface in an axial direction of the bearing G
