置構造。[Scope of Claim for Utility Model Registration] 1. In an end-pivot type valve operating mechanism that opens and closes the intake and exhaust valves of an internal combustion engine via a rocker arm by rotation of a cam, a hydraulic lash adjuster having a built-in plunger that comes into contact with the rocker arm is installed. An arrangement structure for an automatic hydraulic valve gap correction device, in which an oil pocket is formed by providing a wall in a cylinder head so as to surround a contact portion with the opening arm. 2. The hydraulic lash adjuster has a bottomed hollow circular body having an oil hole in the side wall, and is slidably fitted into the body to form a high pressure chamber between the bottom inner surface and the gap of the body, and an oil reservoir chamber. a plunger having an open hollow part and a bottom part with an oil hole; an elastic body provided within the high pressure chamber to urge the plunger to move away from the open end side of the body; The arrangement structure of a hydraulic valve gap automatic correction device according to claim 1, which is a registered utility model and comprises a check valve that controls opening and closing of the oil hole of the plunger, and a check valve cage that holds the check valve.
