A damping force is generated by controlling a flow of oil caused by sliding of a piston in a cylinder with the aid of a disk valve, against extension and compression of a piston rod. An elastic seal member, fixedly attached to a back surface side of the disk valve, is fitted in a recessed portion of a pilot body, by which a pilot chamber is formed and valve opening of the disk valve (33) is controlled by inner pressure in the pilot chamber. The elastic seal member is in abutment with the bottom portion of the recessed portion, and the disk valve is urged toward inner and other seat portions by elasticity of the elastic seal member. This configuration ensures that the disk valve can be closed without a set load provided from deflection of the disk valve, thereby generating a stable low damping force. |
