Claims

[Scope of utility model registration request]

A body including a hydraulic passage, a plunger movably disposed within the body, an oil reservoir chamber formed within the body by the plunger, and a spring biasing the plunger in a direction in which the reservoir chamber is contracted. In the accumulator, a protrusion is formed at the tip of the plunger, the protrusion is fitted in the hydraulic passage to form a leak clearance, and when the plunger moves in the direction of contraction of the reservoir chamber, an accumulator forming an oil damper chamber in the reservoir chamber that communicates with the hydraulic passage through the leak clearance;
