In a lash adjuster used for a valve operating mechanism of an internal combustion engine, there is known a lash adjuster constituted by inserting a cylindrical sleeve into a plunger cap for preventing air from entering a high-pressure chamber located at a lower portion of the lash adjuster. However, in the conventional lash adjuster, since the plunger cap is formed with two side holes which are different in height in the axial direction of the plunger cap, it becomes complicated to regulate the side surface the plunger cap which corresponds to a sliding surface. Therefore, it is problems to be solved by the present invention to provide a lash adjuster in which the side surface of the plunger cap can be easily regulated without disturbing the inflow and outflow of oil and whose machining cost can be kept low. The above problems can be solved by a hydraulic lash adjuster in which two or more cap side holes 27c are provided and all of them are disposed in a plane perpendicular to a shaft center of the body 21. |
