PROBLEM TO BE SOLVED: To provide an attenuation force regulator capable of simply adjusting attenuation force with a simple structure.SOLUTION: A switch valve (6) includes: a needle valve (62G) disposed in an opening part (64C) of a center flow passage (64A) in which working oil flows, and configured to adjust attenuation force by adjusting an opening area of the opening part (64C); and an alternate mechanism (10), a pressing button part (62A) and a spring (66) configured to switch a position of the needle valve (62G) to any of two stages: a first position where the opening area is a first area; and a second position where the opening area is a second area smaller than the first area.SELECTED DRAWING: Figure 3
【課題】簡素に構成され、かつ簡単に減衰力を調整できる減衰力調整装置を提供する。【解決手段】スイッチバルブ(6)は、作動油が流れる中心流路(64A)の開口部(64C)に配され、開口部(64C)の開口面積を調整することによって減衰力を調整するニードル弁(62G)と、ニードル弁(62G)の位置を、前記開口面積が第1面積となる第1位置と、前記開口面積が前記第1面積よりも小さい第2面積となる第2位置との2段階で切り替えるオルタネイト機構(10)、押しボタン部(62A)およびスプリング(66)とを備えている。【選択図】図3
