To provide a detent device for a rotation axis suitable for detent of an outrigger rotation axis when using the outrigger rotation axis as a fixed axis and a device such as a position sensor is installed on an axis identical to the outrigger rotation axis.SOLUTION: There is provided a detent device for a rotation axis in which a frame and an outrigger rotation axis 15 interlock each other by inserting a detent member 1 into an attachment hole 13Hm and a fitting hole 15H in a state where the attachment hole 13Hm and the fitting hole 15H are communicated with each other. The detent member 1 is configured so that an axis member 4 can be moved by elastic deformation of an elastic member 3 constituting an intermediate part sandwiched between a fixed member 2 constituting a base end side and the axis member 4 constituting a tip side. The axis member 4 is always engaged with the fitting hole 15H even when the elastic member 3 is being compressed. The fitting hole 15H has a bottom surface formed into a cone shape, and a tip part of the axis member 4 is formed into a taper shape along the cone shape.SELECTED DRAWING: Figure 7
【課題】アウトリガ回転軸を固定軸として用い、アウトリガ回転軸と同軸に位置センサ等の装置を設置する場合に、アウトリガ回転軸の回り止めに好適な回転軸の回り止め装置を提供する。【解決手段】取付穴13Hmと嵌合穴15Hとを連通させた状態で取付穴13Hm及び嵌合穴15Hに回止部材1を挿入することで、フレームとアウトリガ回転軸15とが互いに係止する回転軸の回り止め装置であって、回止部材1は、基端側を構成する固定部材2と先端側を構成する軸部材4との間に挟まれた中間部を構成する弾性部材3の弾性変形によって軸部材4が可動するように構成されており、弾性部材3が圧縮状態であっても軸部材4は嵌合穴15Hと常に係合しており、嵌合穴15Hは、円錐形状に構成された底面を有し、軸部材4の先端部は、円錐形状に沿ったテーパ状に構成されている。【選択図】図7
