Abstract

Provided is a hydraulic pressure supply device for a vehicle, the hydraulic pressure supply device being configured so that: the number of bends of an oil passage for transporting oil, which is discharged from a mechanical oil pump, to a valve body can be reduced; the oil passage can be shortened; and pressure loss can be reduced. An oil passage constituting member is provided with housing chamber surfaces for constituting the inner surfaces of the rotor housing chambers of a mechanical oil pump; a first discharge oil passage; and the first member joining section of the first discharge oil passage. The valve body is provided with a first body oil passage and with the first body joining section of the first body oil passage. The first member joining section and the first body joining section are joined so as to face each other, and the first discharge oil passage and the first body oil passage are connected.

Description

technical field [0001] The present invention relates to a hydraulic oil supply device for a vehicle, comprising a mechanical oil pump driven by a driving force source of wheels, an oil passage component forming an oil passage connected to the mechanical oil pump, and an The oil passage constitutes a hydraulic pressure control device that supplies the hydraulic pressure supplied to the drive transmission device for the vehicle. Background technique [0002] As the hydraulic oil supply device for a vehicle as described above, for example, a device described in Patent Document 1 below is known. In the technique of Patent Document 1, the oil discharged from the mechanical oil pump is supplied to the valve body B via the oil passage formed in the partition wall Ma of the housing (transmission case M) housing the vehicle drive transmission device. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-57675 [0004] However, in the technique of Patent Document 1, since t...
