<p>A lash adjuster in which, when a plunger descends, a valve element moves to a valve-closed position without delay. A check valve (27) has a valve hole (28) penetrating through a bottom wall (17) of a plunger (12), a retainer (30) placed in a high pressure chamber (25) and vertically moving together with the plunger (12), and a valve element (29) capable of vertically moving in the high pressure chamber (25), between a valve-opened position at which the valve element (29) is separated from the valve hole (28) to be placed on the retainer (30) and a valve-closed position which is located above the valve-opened position and at which the valve element (29) closes the valve hole (28). When the plunger (12) is at a standstill, the valve element (29) is held at the valve-opened position by the self-weight.</p> |
