Amendment November 10, 1981 The scope of claims for utility model registration is amended as follows.

[Scope of Claim for Utility Model Registration] Intake side and exhaust side rocker arms that open and close the intake valve and exhaust valve of each cylinder are arranged so that one end of each cylinder is connected to the axis of the intake camshaft and exhaust camshaft mounted on the cylinder head. It is pivotally supported on a pivot disposed on the center side, and its other ends are brought into contact with the top surfaces of the valve shafts of the intake valve and exhaust valve, and the pivot is connected to the bottomed cylindrical body. a plunger slidably fitted into a body and having a reservoir chamber therein; a check valve interposed between a hydraulic chamber formed at the bottom of the body and the reservoir chamber; A hydraulic latch adjuster is provided at the tip of the plunger protruding outside the body of the hydraulic latch adjuster, which is provided with a spring member inserted into a chamber and biasing the plunger in the direction of extension, and on the upper surface of the cylinder head, A passage member having an oil supply passage for the lash adjuster of each cylinder is installed, and a cylinder head is bored approximately in the direction of the cylinder axis to connect the oil supply passage in the passage member and the pressure oil inlet of the lash adjuster. A cylinder head for a multi-cylinder engine, characterized in that the cylinder heads are interconnected through hydraulic oil passages within the cylinder head.

Claims (1)

[Scope of utility model registration request] An intake-side rocker arm that opens and closes the intake valve and exhaust valve of each cylinder has one end pivoted on a pivot located closer to the center of the cylinder than the axes of the intake camshaft and exhaust camshaft mounted on the cylinder head. The pivot is supported by a cylindrical body with a bottom, and the pivot is slidably fitted into the body, and the other end thereof is brought into contact with the top surfaces of the valve shafts of the intake valve and the exhaust valve. A plunger having a reservoir chamber therein, a check valve interposed between a hydraulic chamber formed at the bottom of the body and the reservoir chamber, and a check valve inserted into the hydraulic chamber to move the plunger in an extension direction. In the hydraulic lash adjuster provided at the tip of the plunger protruding outside the body, the oil supply passage for the lash adjuster of each cylinder is provided on the upper surface of the cylinder head. A passage member is installed, and the oil supply passage in the passage member and the pressure oil inlet of the lash adjuster are communicated with each other through a hydraulic oil passage in the cylinder head that is bored approximately in the direction of the cylinder axis. The cylinder head of a multi-cylinder engine is characterized by:
