Abstract
A lash adjuster includes a plunger and a partitioning member inserted into the plunger. The plunger has a bottom wall with a valve hole and a peripheral wall having an oil passage hole. The plunger defines a high-pressure chamber between the bottom wall and a body. The partitioning member has a baffle having first and second plate surfaces. The baffle has an upper end serving as oil passage end. The plunger has an interior divided into two spaces. The passage hole is located at one space side. An oil passage is defined by an inner peripheral wall surface of the plunger and the first plate surface. A low-pressure chamber is defined at the other space side to store hydraulic fluid. The low-pressure chamber supplies the fluid through the valve hole into the high-pressure chamber and is defined by the inner peripheral wall surface of the plunger and the second plate surface.
