摘要： PROBLEM TO BE SOLVED: To provide a sealing type lash adjuster and a gas filling method for a sealing type lash adjuster capable of suppressing function as the lash adjuster from being impaired by suppressing rising of an internal pressure to a low degree at shortening of a plunger.
SOLUTION: The sealing type lash adjuster 100 having a reservoir chamber 10 filled with a gas together with an oil has the gas filled in the state that the pressure is reduced to a lower degree than an atmospheric pressure in the reservoir chamber 10 as the gas. Thereby, rising of the internal pressure can be suppressed to a lower degree at shortening of the plunger 2 as compared with the case where it has, for example, the gas filled at the atmospheric pressure and the gas filled at pressurization. Accordingly, thereby, the function as the lash adjuster can be suppressed from being impaired caused by the fact that pressure difference at operation is large.
