PROBLEM TO BE SOLVED: To provide a piston cylinder device, which can be applied to a door check device that is non-penetrating rod type and provide volume compensation in a cylinder space in which fluid is included so as not to affect a movement operation of a piston member in the cylinder space.SOLUTION: A piston cylinder device 100 comprises: a main cylinder member 1; a main piston member 2; a main rod member 3; a sub-cylinder member 4; a sub-piston member 5; a sub-rod member 6; and a pair of valve units (a first valve unit 7 and a second valve unit 8). A main cylinder space S is formed in the main cylinder member 1. A sub-cylinder space V is formed in the sub-cylinder member 4. The sub-rod member 6, the main rod member 3 and the sub-cylinder space V are formed so that a difference Spr (=Sps-Sp) between a cross section Sps of the sub-cylinder space and a cross section Sp of the sub-rod member is equal to the sum (S+Sp) of a cross section S of the main rod member and the cross section Sp of the sub-rod member.SELECTED DRAWING: Figure 4

    【課題】 ロッド非貫通タイプのドアチェック装置に適用でき且つシリンダ空間内におけるピストン部材の移動動作に影響を及ぼさないように、流体が封入されたシリンダ空間の体積補償がなされるピストンシリンダ装置を提供する。【解決手段】 ピストンシリンダ装置100は、主シリンダ部材1と、主ピストン部材2と、主ロッド部材3と、副シリンダ部材4と、副ピストン部材5と、副ロッド部材6と、一対のバルブユニット(第一バルブユニット7、第二バルブユニット8)と、を備える。主シリンダ部材1内に主シリンダ空間Sが形成され、副シリンダ部材4内に副シリンダ空間Vが形成される。副シリンダ空間の断面積Spsと副ロッド部材の断面積Spとの差の大きさSpr(=Sps−Sp)が、主ロッド部材の断面積Sと副ロッド部材の断面積Spとの和の大きさ(S+Sp)に一致するように、副ロッド部材6、主ロッド部材3、及び、副シリンダ空間Vが形成される。【選択図】 図4
