緩衝器の減衰力調整装置。 A valve for damping force adjustment is provided in the middle of a passage connecting the oil chamber of the damper body and the oil chamber of the tank, and two passages connected to the passage are provided in parallel in the valve body of the valve, and one passage is provided with a valve for adjusting the damping force. A movable needle valve is provided to be able to open and close freely, a leaf valve is provided in the other passage to be able to be opened and closed, and a spring is interposed between the base end of the needle valve and the leaf valve, and the spring opens the needle valve. direction and the leaf valve in the closing direction, and the needle valve is driven from the outside via a driving member, which drives the needle valve to adjust the opening area of one passage, and at the same time reduces the load on the leaf valve via the spring. In the hydraulic shock absorber for adjusting the leaf valve, the base end of the leaf valve is supported by a valve seat, the spring urges the leaf valve via a valve holder, and the valve holder is attached to the outer end side contact portion of the leaf valve. 1. A damping force adjusting device for a hydraulic shock absorber, characterized in that the damping force adjusting device has a proximal contact portion, and an inner diameter of the proximal contact portion is smaller than an outer diameter of the valve seat.
