The purpose of the present invention is to suppress the inflow of air to a high pressure chamber while reducing the number of components. A plunger (14) is slidably engaged into a body (13). A reservoir (24) is formed in the plunger (14) and a communication hole (25) that enables communication between the interior and the exterior is formed in a head portion (19) of the plunger. A high pressure chamber (28) is formed inside the body (13) between the body and a plunger bottom (20), and an oil supply hole (40) is formed in a plunger peripheral wall (21). A return spring (41) is interposed between the body (13) and the plunger (14), and a valve mechanism (42) is provided on the plunger bottom (20).
