PROBLEM TO BE SOLVED: To provide a buffer capable of suppressing increase of its weight even in a case of securing a gas chamber volume constituting a gas spring.SOLUTION: A buffer includes: a damper body D that has a cylinder 1 inside which an operation chamber L is formed, a piston 2 movably inserted into the cylinder 1 and configured to section the operation chamber L into an expansion side chamber L1 and a pressure side chamber L2, and a rod 3 connected to the piston 2 and extending to the outside of the cylinder 1; a main spring (gas spring) S1 having a first gas chamber G1 expanding/contracting according to expansion/contraction of the damper body D; and a reservoir R provided outside the first gas chamber G1, and having a liquid chamber L3 communicating with the operation chamber L and a gas chamber G3 communicating with the first gas chamber G1.SELECTED DRAWING: Figure 1

    【課題】 気体ばねを構成する気室容積を確保したとしても、重量が増加するのを抑制できる緩衝器を提供する。【解決手段】 内部に作動室Lが形成されるシリンダ1と、シリンダ1内に移動可能に挿入されて作動室Lを伸側室L1と圧側室L2に区画するピストン2と、ピストン2に連結されてシリンダ1の外方へ延びるロッド3とを有するダンパ本体Dと、ダンパ本体Dの伸縮に伴って拡縮する第一気室G1を有するメインばね(気体ばね)S1と、第一気室G1の外部に設けられ、作動室Lに連通する液室L3と、第一気室G1に連通する気室G3とを有するリザーバRとを備える。【選択図】 図1
