<p>A lash adj uster includes a body (11), a plunger (12) inserted into the body (11) and a partitioning member (13, 13A) inserted into the plunger (12). The plunger (12) has a bottom wall (18) with a valve hole (20) and a peripheral wall (19) having an oil passage hole (26). The plunger (12) defines a high-pressure chamber (22) between the bottom wall (18) and the body (11) . The partitioning member (13, 13A) has a plate-like baffle (39) located opposite the passage hole (26). The baffle (39) has an upper end serving as an oil passage end (33) located above the passage hole (26). The plunger (12) has interior divided into two spaces by the baffle (39). The passage hole (26) is located at one space side. An oil passage (40) is defined at one space side. A low-pressure chamber (23) is defined at the other space side to store hydraulic fluid flowing through the passage hole (26), the oil passage (40) and the passage end (33). The low-pressure chamber (23) supplies the fluid through the valve hole (20) into the high-pressure chamber (22).</p> |
