Abstract: An oil supply device includes an oil pump and an oil control valve. The oil control valve is connected to a control oil chamber of the oil pump via a control oil passage that includes an oil descent passage and an oil rise passage. One end of the oil descent passage on the control oil chamber side is disposed at a position closer to a bottom of the vehicle than the other end on the oil control valve side. The oil rise passage is disposed at a position closer to the control oil chamber side than the oil descent passage. One end of the oil rise passage on the control oil chamber side is disposed at a position closer to a top of the vehicle than the other end on the oil control valve side.

Abstract: A variable displacement oil pump includes an adjustable member that is configured to shift according to changes in pressure inside a control oil chamber. The adjustable member has a long hole. A guide pin is disposed inside the long hole. The guide pin is fixed to either a housing or a cover of the variable displacement oil pump. The width of the long hole is larger at a part of the long hole farther away from a fixed end of the guide pin in its lengthwise direction than at a part thereof closer to the fixed end.
