を特徴とする油圧ラツシユアジヤスタ。 The device includes a cylindrical body with a bottom and a plunger that is slidably fitted into the body and forms a high-pressure chamber within the body, and the plunger has an oil passage that supplies hydraulic oil to the high-pressure chamber. In the high pressure chamber, there is a check ball and this check ball is always attached in the closed direction to open and close the opening of the oil passage at the inner end of the plunger and to prevent backflow of hydraulic oil from the high pressure chamber. In the hydraulic latch adjuster, the hydraulic latch adjuster is provided with a check valve consisting of an elastic member that pushes the plunger, and an end of the plunger on the high pressure chamber side has an outer circumferential surface thereof and a surface in which the oil passage is opened. A hydraulic latch adjuster characterized by having a communicating hole formed therein.
