A recess hole is connected to a radially outer side of an oil passage portion and forms an oil supply passage. A check valve part has: a valve seat portion provided in the oil passage portion to form a valve seat; a sleeve having one end connected to the valve seat portion; a lateral hole to communicate an internal space of the sleeve with outside of the sleeve; and a valve body provided in the sleeve so as to be separated from the valve seat or in contact with the valve seat. The lateral hole has an opening exposed to outside of the sleeve, and a range of the opening overlaps with a range of the recess hole in an axial direction of the sleeve.
