A self-contained type lash adjuster is used in the valve train mechanism for internal combustion engines. The lash adjuster comprises an adjuster body having an axial hollow, a plunger body reciprocating within the axial hollow of the adjuster body, a reservoir chamber formed in the plunger body, a pressure chamber formed between the adjuster and plunger bodies, a check valve permitting an oil flow only in the direction from the reservoir chamber to the pressure chamber, a diaphragm positioned in the upper portion of the reservoir chamber, and a plunger return spring biasing the plunger body. The lash adjuster is supported in a recess in a valve spring retainer which is fixedly secured to the end of a valve stem.
