Claims

[Scope of utility model registration request]

The upper part engages with a bushing rod seat that engages with the bushing rod, and the lower part contacts a spring supported at the bottom of the cylindrical body, and is inserted into the body so as to be able to slide up and down together with the bushing rod seat. A diaphragm having a diaphragm press-fitted into the inner periphery of the upper opening of the plunger, and a sealing member installed between the outer periphery of the plunger and the inner periphery of the body allow the plunger to be connected to the outside. In the hydraulic lifter, the hydraulic lifter includes a reservoir that is sealed and communicates with a pressure chamber at the bottom of the body through a check valve and a leak gap between the body and the plunger, and in which oil is sealed in the reservoir and the pressure chamber. A sealed hydraulic lifter, characterized in that a stopper member fixed to the upper part of the plunger comes into contact with an upper end of a metal ring embedded and fixed in the plunger.
