PROBLEM TO BE SOLVED: To provide a door check device with a simple constitution capable of generating large retaining force at an arbitrary open position.SOLUTION: A door check device 1 includes a case 2, a rod-like member 3, a pinion gear 4 rotated by axial movement of the rod-like member 3, an inner case 5 fixed and disposed in the case 2 and having a magnetic fluid enclosed in an inside thereof, a vane wheel connected to the pinion gear 4 and rotated in the inner case 5, a retaining member 7 disposed in the case 2 to be movable between an original position and an operation position, a permanent magnet 8 retained by the retaining member 7 to be disposed in a position where magnetic force is applied to the magnetic fluid when the retaining member 7 is in the original position and to be disposed in a position where the magnetic force is not applied to the magnetic fluid when the retaining member 7 is in the operation position, a pair of compression springs 9a and 9b for imparting elastic force to the retaining member 7 so that the retaining member 7 is returned to the original position, and a pair of friction members 10a and 10b attached to the retaining member 7 and frictionally engaged with the rod-like member 3.
【課題】任意の開度位置で大きな保持力を発生させることができる簡易な構成のドアチェック装置を提供する。【解決手段】ドアチェック装置１は、ケース２と、棒状部材３と、棒状部材３の軸方向移動により回転させられるピニオンギア４と、ケース２内に固定配置され磁性流体が内部に封入された内側ケース５と、ピニオンギア４に連結され内側ケース５内で回転する羽根車と、ケース２内にて原位置と作動位置とに移動可能に配設された保持部材７と、保持部材７が原位置にあるときに磁性流体に磁力が印加され、作動位置にあるときに磁性流体に磁力が印加されない位置に配置するように保持部材７に保持された永久磁石８と、保持部材７が原位置に戻るように保持部材７に弾性力を付与する一対の圧縮バネ９ａ，９ｂと、保持部材７に取付けられるとともに棒状部材３に摩擦係合する一対の摩擦部材１０ａ，１０ｂと、を備える。【選択図】図３
