Claims

[Scope of utility model registration request]

A first having a shaft hole with an open end and communicating with a hydraulic pressure supply source.
an adjuster body having an oil supply hole formed therein; a storage chamber movably disposed in the shaft hole of the adjuster body and having a hollow shape therein; and a second oil supply hole that communicates the storage chamber with the first oil supply hole. a plunger having an oil supply hole formed therein; a pressure chamber formed between the adjuster body and the bottom wall of the plunger; and a communication line formed in the bottom wall of the plunger that communicates the storage chamber and the pressure chamber. A hydraulic type having a hole, a check valve that allows pressure oil to flow only from the storage chamber to the pressure chamber through the communication hole, and a plunger return spring that biases the plunger toward the open end side of the adjuster body. In the valve clearance correction device, at least one of the first oil supply hole and the second oil supply hole is configured to allow oil to flow in a circumferential direction within the storage chamber.
A hydraulic valve clearance correction device characterized in that the opening is opened in a tangential direction to the axis of the storage chamber so as to obtain the same.
