Claims

[Scope of utility model registration request]

A cylinder containing hydraulic oil, a piston rod that fluidly and slidably penetrates the open end of the cylinder, and a piston rod that is assembled to one end of the piston rod and is slidably inserted into the cylinder. a piston that divides the inside of the cylinder into two oil chambers; an oil hole provided in the piston that communicates the two oil chambers; and a valve body that elastically closes the oil hole from the opening side of one end. comprising a valve mechanism having;
” In the hydraulic shock absorber for a vehicle, the hydraulic oil in one of the two oil chambers is caused to flow into the other oil chamber through the valve mechanism by relative sliding of the piston, wherein the valve mechanism The constituting valve body is provided with a passage that communicates with the oil passage provided in the piston independently from the oil passage hole, and a passage is provided at one end of the piston rod facing the valve body at a predetermined interval. A flexible cylindrical or annular partition member is interposed in the axial direction between the retainer point and the fixed retainer point to form a pressure chamber inside the valve body, and this pressure chamber is connected to the communication path and the oil passage hole. A hydraulic shock absorber for a vehicle, characterized in that the hydraulic shock absorber communicates with one of the oil chambers through the oil chamber.
