To provide a buffer capable of suppressing a buffer body or a tube member from being damaged by a throttle member even in a case where the throttle member is provided so as to form an annular restriction passage between itself and the buffer body or tube member.SOLUTION: A buffer divides a liquid storage chamber formed between a buffer body D and a tube member T on an outer periphery thereof into an upper chamber r1 and a lower chamber r2, and comprises a throttling member C that forms an annular restriction passage O between itself and the buffer body D or tube member T that gives resistance to the flow of liquid moving between these chambers. The throttling member C is movable in a radial direction.SELECTED DRAWING: Figure 2
【課題】 緩衝器本体又はチューブ部材との間に環状の制限通路を形成する絞り部材を設ける場合であっても、その絞り部材によって緩衝器本体又はチューブ部材が傷付くのを抑制できる緩衝器を提供する。【解決手段】 緩衝器が緩衝器本体Dとその外周のチューブ部材Tとの間に形成される液溜室を上室r1と下室r2とに区画するとともに、これらの間を移動する液体の流れに抵抗を与える環状の制限通路Oを緩衝器本体D又はチューブ部材Tとの間に形成する絞り部材Cを備え、その絞り部材Cが径方向へ移動可能とされている。【選択図】 図2
