PROBLEM TO BE SOLVED: To cause a mechanism for restricting a motion of a moving member to have a stopper function for restricting a motion range of the moving member and a function acting as a damper against the moving member.SOLUTION: A stopper mechanism 10 having a damper function comprises: a casing 12 having a cylinder space 14 therein; a piston 20 acting as a moving member sliding in a stroke range S being guided by an inner wall surface 16 of the cylinder space 14; and a gas supply passage 50 for supplying gas with a supply pressure Pto a first communication hole 33 and a second communication hole 34 provided respectively at a first gas pressure chamber 31 and a second gas pressure chamber 32 partitioned by the piston 20 in the cylinder space 14, and the first communication hole 33 and the communication hole 34 are disposed in a communication range that is narrower in advance than the stroke range of the piston.SELECTED DRAWING: Figure 1
【課題】移動体の運動を規制する機構として、移動体の移動範囲を規制するストッパ機能と、移動体に対しダンパとして働く機能を持たせることである。【解決手段】ダンパ機能付ストッパ機構10は、シリンダ空間14を内部に有する筐体12と、シリンダ空間14の内壁面16に案内されてストローク範囲S内で摺動する移動体であるピストン20と、シリンダ空間14においてピストン20で仕切られる第1気体圧室31と第2気体圧室32にそれぞれ設けられる第1連通穴33と第2連通穴34に供給圧力PSの気体が供給される気体供給路50と、を備え、第1連通穴33と第2連通穴34は、ピストンのストローク範囲よりも予め狭く設定される連通範囲内に設けられる。【選択図】図1
