備えることを特徴とするオイルバツフア。 A piston rod that receives a colliding object, a cylinder that supports the piston rod freely through bearings in the piston part and the rod cover part, and a damping force is created by applying resistance to the flow of hydraulic oil that is displaced by the contraction of the piston rod. An oil buffer comprising: a damping valve; a displacement detection spring that is compressed in response to contraction of a piston rod; and means for increasing a set load of the damping valve in accordance with the spring load.
