Claims

[Claims for Utility Model Registration] (1) A cylindrical plunger is slidably fitted into a cylindrical cylinder body with one end closed, and a cylindrical plunger head with one end closed is slid in contact with the plunger in the opening direction of the cylinder body. A high-pressure chamber is formed in the part surrounded by the bottom of the plunger and the cylinder body, a reservoir chamber is formed inside the plunger and the plunger head, and a reservoir is inserted into the bottom of the plunger through the opening. In a hydraulic valve lash adjuster in which a return spring is disposed for repulsion between a check valve that allows flow only to a high pressure chamber, a plunger and a body, at the closed end of the plunger head and cylinder body, A hydraulic valve lash adjuster characterized by forming a concave spherical part that engages with a convex spherical part of a Rocker arm. (2) A utility model registration request in which the cylinder body is fitted into a bottomed mounting bore provided in the cylinder head with its bottom at the bottom, and the concave spherical part of the plunger head is engaged with the convex spherical part at one end of the rocker arm. Hydraulic valve lash adjuster as described in scope item (1). (3) Request for registration of a utility model in which the plunger head is slidably fitted into a bottomed mounting bore provided in the cylinder head, and the concave spherical part of the cylinder body engages with the convex spherical part at one end of the rocker arm. Hydraulic valve lash adjuster as described in item (1).
