摘要

PROBLEM TO BE SOLVED: To obtain a pressure oil supply structure capable of properly leading pressure oil into a hydraulic control device in a pressure oil supply structure having a structure in which a distance between an oil pump and the hydraulic control device is comparatively long.

SOLUTION: A separate plate SP and a lower valve body LVB, with respect to an upper valve body UVB, are provided with an overhung part over hanging on a discharge port side of the oil pump. The overhung part is provided with a first introduction oil passage PI1 formed between the separate plate SP and the lower valve body LVB for receiving pressure oil from the oil pump and leading it to the upper valve body UVB disposed side. A drooping wall Wd drooping from a case MC is provided at a position opposing the upper end of a seal wall part WS of the lower valve body LVB to sandwich the separate plate SP.
