Abstract
A lash adjuster includes a plunger inserted into a body and defining a pressure chamber in the body, and a spacer. The plunger is moved axially when a working fluid flows into or out of the pressure chamber so that a volume of the pressure chamber is increased or reduced. The plunger has a bottom wall defining the pressure chamber, a peripheral wall rising from an outer periphery of the bottom wall and an outer peripheral surface having an annular groove located at a height position confined in a thickness range of the bottom wall. When fitted in the groove, the spacer has a plate width equal to a separating distance between a groove bottom and an inner peripheral face of the body to fill a gap between the body and the plunger. The spacer has a flow path through which the working fluid introduced into the pressure chamber leaks.
