PURPOSE:To heighten buffer characteristic setting freedom while using a bottomed cushioning elastic body. CONSTITUTION:An elastic body 18 is fitted into the longitudinal intermediate position of a piston rod 11, and the piston rod through-part of a cylinder 9 is provided with a stopper member 13 with the stopper face 13a. The axial length of the elastic body 18 is set to be sufficiently longer than the inner diameter of a suspension spring 5, and its outer peripheral surface is brought close to the suspension spring 5. The lower end of the suspension spring 5 is brought into contact with the vicinity of the stopper face 13a. The length of the suspension spring 5 can be thereby secured, and the suspension spring 5 can be assisted by the elastic body 18. The buffer characteristic setting width of the suspension spring 5 is also enlarged, and the buffer characteristic can be set with the elastic force of the elastic body 18 added thereto. |
