車用油圧緩衝器。 An inner tube with a piston at its tip is slidably inserted into an outer tube with a seat pipe erected inside, and a check valve is provided that only allows oil to flow from oil chamber B below the piston to oil chamber A above. In a hydraulic shock absorber for a two-wheeled vehicle, which is provided in the piston and communicates the oil chamber A and the oil passage in the seat pipe via an orifice, a relief port is formed on the wall surface of the seat pipe facing the oil chamber A,
A two-wheeled vehicle characterized in that a relief passage is provided between the relief port and the oil passage in the seat pipe, in which a relief valve that opens when the pressure in the oil chamber A increases and an orifice different from the orifice are arranged in series. Hydraulic buffer.
