Claims

[Scope of utility model registration request]

The oil chamber is divided into an upper oil chamber and a lower oil chamber by a piston inserted into the cylinder, and an oil passage with a throttle valve is formed in the piston to communicate the upper and lower oil chambers. A bypass oil passage parallel to the throttle valve of the piston is bored in the circumferential sliding inner wall, and a rotary valve is rotatably and closely inserted into the sliding inner wall, and a through piston rod protruding from the piston is provided with a bypass oil passage. A damping force switching type hydraulic shock absorber, characterized in that the inner end of an inserted control rod and the rotary valve can be slid in the axial direction, and have a rotational connection structure based on irregular fitting with a clearance. .
