PROBLEM TO BE SOLVED: To provide a free stop door check device capable of compensating a volume of an operation chamber without making a rod member penetrate through a fluid inclusion space.SOLUTION: A door check device 100 comprises: a first cylinder part 8 on which an operation chamber S is installed; a first piston member 4, which partitions the operation chamber S installed on the rod member 3 into a first operation space S1 and a second operation space S2; a second cylinder part 9 in which a volume compensation chamber P is formed; a second piston member 5, which is disposed in the volume compensation chamber P and partitions the volume compensation chamber P into a first volume compensation space P1 and a second volume compensation space P2; a first cylinders connecting passage 21, which communicates the first operation space S1 and the first volume compensation space P1; and a second cylinders connecting passage 22, which communicates the second operation space S2 and the second volume compensation space P2. When the second piston member 5 moves in the volume compensation chamber P, a volume variation of the first volume compensation space P1 is less than that of the second volume compensation space P2.SELECTED DRAWING: Figure 3

    【課題】 ロッド部材が流体封入空間を貫通することによらずに作動室の体積補償を行うことができるフリーストップドアチェック装置を提供すること。【解決手段】 ドアチェック装置100は、作動室Sが形成された第1シリンダ部分8と、ロッド部材3に取り付けられ作動室Sを第1作動空間S1と第2作動空間S2とに区画する第1ピストン部材4と、体積補償室Pが内部に形成された第2シリンダ部分9と、体積補償室P内に配設され体積補償室Pを第1体積補償空間P1と第2体積補償空間P2とに区画する第2ピストン部材5と、第1作動空間S1と第1体積補償空間P1とを連通する第1シリンダ間接続通路21と、第2作動空間S2と第2体積補償空間P2とを連通する第2シリンダ間接続通路22とを備える。体積補償室P内を第2ピストン部材5が移動する際に、第1体積補償空間P1の容積変化量が第2体積補償空間P2の容積変化量よりも小さくされる。【選択図】 図3
