Abstract

The present invention provides a vehicle drive device capable of ensuring sufficient installation space for a hydraulic control device and a capacity of an oil pan. The drive device (1) for a vehicle is configured by accommodating a speed change mechanism (3) and an electric motor (MG2) in a case (D), and disposing a hydraulic control device (7) on the outer wall of the case (D), wherein the case (D), there is an opening (Da) at one end of the case main body (D') into which the speed change mechanism (3) and the motor (MG2) can be inserted, and the other end side of the case main body (D') is connected to the case main body (D') integrally has the other end wall portion (Db) provided with a shaft support portion (Db1) for supporting the output shaft (14) of the speed change mechanism (3).

Description

technical field [0001] The present invention relates to a driving device for a vehicle, which is composed of a transmission mechanism having a frictional engagement mechanism controlled by hydraulic pressure and a motor housed in a casing, and a device for controlling the frictional engagement mechanism to the frictional engagement mechanism is arranged on the outer wall of the casing. A hydraulic control device that supplies hydraulic pressure to the mechanism. Background technique [0002] Regarding a vehicle drive device including a transmission mechanism and an electric motor, for example, Patent Document 1 below discloses a configuration as shown in FIG. 4 . This FIG. 4 shows a side sectional view of a vehicle drive device 51 described in Patent Document 1. As shown in FIG. This vehicle driving device 51 comprises a damper device 53, a first motor / generator 54, a power distribution mechanism 55 composed of a planetary gear mechanism, a second The motor / generator 56 an...
