換装置。 A shock absorber for a vehicle suspension includes an oil passage provided in the piston rod that communicates the piston lower chamber with the outside of the cylinder, a hydraulic pump capable of pumping hydraulic oil into the piston lower chamber through the oil passage, and a hydraulic pump capable of pumping hydraulic oil from the piston lower chamber to the piston lower chamber. A shock absorber damping force switching device comprising a control valve that closes an upper chamber inlet port of a piston through which hydraulic oil flows to an upper chamber of the piston by hydraulic pressure applied to the oil passage.
