タ。A cylindrical body, a plunger that slides within the body, a reservoir defined within the plunger, a pressure chamber defined by the external pressure-receiving end surface of the plunger, and the inner circumferential surface of the body and the reservoir provided on this pressure-receiving surface. A check valve mechanism that communicates with the chamber, a leak clearance consisting of the inner circumference of the body and the outer circumference of the plunger, a port provided on the wall of the plunger that communicates with the reservoir, and a body that communicates with the port and communicates with the outside of the body. A hydraulic lash adjuster is provided with an oil supply port provided in the wall, and the opposite end of the plunger from the pressure receiving end surface is connected to an adjacent valve drive mechanism element through a cup attached to the end. A hydraulic lash adjuster characterized in that an annular groove is formed only on the outer peripheral surface of the body so that the supply port is located at the bottom of the groove.
