To provide an attachment detaching device that does not cause looseness of an attachment in order to regulate the rotation of a screw shaft.SOLUTION: In an approaching/separating means of an attachment detaching device 1, a screw shaft 5, which has a first male thread 53 and a second male thread 54 that are reverse threads for each other by interposing an intermediate part 51 between them, is held by an intermediate support part 24 that an arm connection part 2 has so that the intermediate part 51 is unmovable and rotatable. A first female thread 43 of a movable hook 4 is screwed to the first male thread 53, and a second female thread 61 of a pressing nut 6 is screwed to the second male thread 54. A coil spring 64 that deforms elastically is interposed between the pressing nut 6 and the intermediate part 51. A member support part 25 is provided with an operation member 7 that rotates coaxially with the screw shaft 5 by receiving a rotation operation from outside and a stopper member 8 that regulates or releases the rotation of the operation member 7.SELECTED DRAWING: Figure 3
【課題】ネジ軸の回転を規制するためにアタッチメントのがたつきを発生させないアタッチメント着脱装置を提供する。【解決手段】アタッチメント着脱装置１の接近離反手段は、中間部51を挟んで逆ネジとなる第１雄ネジ53及び第２雄ネジ54を有するネジ軸５が、アーム接続部２の有する中間支持部24に前記中間部51を移動不能及び回転自在に保持され、可動フック４の第１雌ネジ43と第１雄ネジ53とを螺合させ、押圧ナット６の第２雌ネジ61と第２雄ネジ54とを螺合させ、押圧ナット６と中間部51との間に弾性変形するコイルバネ64を介在させ、外部からの回転操作を受けてネジ軸５と同軸で回転する操作部材７と、前記操作部材７の回転を規制又は解除するストッパ部材８とを部材支持部25に設けて構成される。【選択図】図３
