PROBLEM TO BE SOLVED: To provide a door check device that is non-penetrating rod type and has a reduced resistance fluctuation amount against an opening and closing control force.SOLUTION: A piston inner space 71 is formed in a piston member 4. In the piston inner space 71, a volume compensation member 7 is disposed. The volume compensation member comprises: a volume compensation piston member 72, which partitions the piston inner space 71 into a volume compensation space 71a and a pressure generating space 71b; and a compression spring 73, which is disposed in the pressure generating space 71b and applies pressure based on an elastic force to the volume compensation space 71a through the volume compensation piston member 72. A cross-sectional shape of a fluid inclusion space S in a vertical face in a movement direction of the piston member 4 in the fluid inclusion space S of a cylinder member 2 is formed into elliptical or oval shape.SELECTED DRAWING: Figure 4
【課題】 ロッド非貫通タイプであって、且つ、開閉操作力に対する抵抗力の変動量が小さくされたドアチェック装置を提供すること。【解決手段】 ピストン部材４内に、ピストン内空間７１が形成され、ピストン内空間７１内には、ピストン内空間７１を体積補償空間７１ａと圧力発生空間７１ｂとに区画する体積補償用ピストン部材７２と、圧力発生空間７１ｂ内に設けられ、体積補償用ピストン部材７２を介して弾性力に基づく圧力を体積補償空間７１ａに印加する圧縮バネ７３と、を有する体積補償部材７が配設される。また、シリンダ部材２の流体封入空間Ｓ内におけるピストン部材４の移動方向に垂直な面内における流体封入空間Ｓの断面形状が、楕円形状、又は、小判型形状にされている。【選択図】 図４
