ABSTRACT:
A hydraulic buffer of the type in which a damping force can be controlled has a piston rod projecting from a cylinder, and a bracket attached to the projecting end of the piston rod. The bracket has at least two claws which are bent inwardly to face each other. A retainer is provided with at least two fitting portions having flukes and the fitting portions are adapted to engage with respective claws of the bracket. An actuator is attached to the retainer to control the damping force of the buffer. A spring device is provided for biasing the retainer to prevent the flukes from being disengaged from the corresponding claws of the bracket, and the spring device supports the retainer on the bracket.
