Claims

[Claims for Utility Model Registration] (1) Hydraulic oil in a chamber equipped with concentric inner and outer cylinders that are relatively movable and isolated by a check valve, in response to changes in the relative positions of both cylinders, A shock absorber that generates a buffering force by flowing through a check valve, a biasing means that applies a biasing force to the shock absorber that resists fluctuations in the relative position of both cylinders, an adjusting handle, and a shock absorber that abuts the biasing means. is movably attached to the shock absorber and connected to the adjustment handle via hydraulic oil, and is moved under pressure by the hydraulic oil flowing in response to the operation of the adjustment handle, thereby biasing the biasing means. An adjusting mechanism equipped with a movable member that fluctuates the force, a check valve control means attached to the shock absorber so that the check valve can be turned on and off from the outside, and a check valve control means disposed on the shock absorber to control the shock absorber. A suspension device equipped with a stop mechanism that softens the impact caused by contact between both cylinders. (2) The check valve is a slot valve, and the check valve mechanism controls the check valve on and off by pulling a flexible wire connected to the slot valve. Suspension device. (3) The stop mechanism is a rubber disposed at the base of one cylinder so as to be able to come into contact with the free end of the other cylinder, and the biasing means of the adjust mechanism is a compression spring disposed between both cylinders. A suspension device according to claim 1 or 2 of a certain utility model registration claim. (4) Claims 1 to 3 of the utility model registration claim, wherein the shock absorber is disposed together with a pantograph mechanism between a fixed lower frame and an upper frame fixed to the seat cushion frame. Suspension device.
