Patent ID: 8573953

Claim:
A mounting structure for mounting a separate shaft type oil pump in a case of a transmission, wherein the separate shaft type oil pump is driven by a shaft that is separate from and rotated in cooperation with a shaft arranged along a torque input route extending from an engine to the transmission to supply hydraulic oil to a transmission oil pressure control mechanism, the mounting structure comprising: a spacer coupler that fastens the oil pump to the transmission case, the spacer coupler including a plurality of spacers that couple the oil pump and the transmission case; an oil passage formed in the spacers of the spacer coupler to connect an oil pressure system, which includes the oil pressure control mechanism, and the oil pump; a manual shaft for operating the transmission, arranged in a clearance between the spacers of the spacer coupler; and wherein the spacers of the spacer coupler are separated from each other to form the clearance allowing for arrangement of the manual shaft between the spacers.
