液圧振動吸収装置。 A body that has an inner hole therein, and a piston that is assembled into the inner hole of the body in a liquid-tight manner and slidable in the axial direction to form a liquid chamber, and that slides according to an increase or decrease in the volume of the liquid chamber. , comprising an elastic member interposed between the back of the piston and a holder assembled to the body to elastically restrict an increase in volume of the liquid chamber;
In a hydraulic vibration absorbing device that is interposed in a hydraulic circuit so that the fluid chamber communicates with the fluid pressure circuit to absorb hydraulic vibrations occurring in the hydraulic circuit, the hydraulic vibration absorber extends from an inner hole of the body of the piston. An annular flange extending toward the outer periphery is provided on the back, and an annular stepped portion is integrally formed in the intermediate portion of the holder to come into contact with the annular flange and prevent the piston from sliding when the piston moves a predetermined amount. A hydraulic vibration absorption device characterized by:
