PROBLEM TO BE SOLVED: To provide a through-axle fitting device capable of fitting a through-axle without carrying out screw fastening work.SOLUTION: This through-axle fitting device is provided with: an annular engaging groove 11 provided at one end of a through-axle 1; and a stopper body 2 provided with an engaging body 21 engaged with the engaging groove 11. The stopper body 2 is provided with: the engaging body 21; an inner cylinder fitted to the end of the through-axle 1 so as to be detached; and an outer cylinder 23 fitted to the inner cylinder so as to be movable in an axial direction. The engaging body 21 engaged with the through-axle engaging groove 11 so as to be disengaged is fitted into the through-hole 24 of the inner cylinder. The outer cylinder 23 is provided with an annular stopper convex part 26 that holds the engaging body 21 in the state of being engaged with the engaging groove 11. A spring 5 is disposed between the inner cylinder and the outer cylinder 23, and the inner cylinder and the outer cylinder 23 are urged in a separating or attracting direction by the spring 5.SELECTED DRAWING: Figure 2
【課題】ネジの締結作業を行うことなくスルーアクスルを着脱することのできる、スルーアクスルの装着装置を提供すること。【解決手段】スルーアクスル1の一端部に設けられた環状の係止溝11と、この係止溝11に係止される係止体21を備えたストッパー体2とで構成する。前記ストッパー体2は、前記係止体21と、前記スルーアクスル1の端部に着脱可能に嵌装される内筒と、この内筒に対して軸方向に移動可能に嵌装された外筒23とを備えている。前記内筒の透孔24にスルーアクスルの係止溝11に係脱自在に係止する係止体21が装着されている。前記外筒23は、前記係止体21を係止溝11への係止状態に保持する環状のストッパー凸部26を備え、前記内筒と外筒23との間にスプリング5が配設され、このスプリング5によって前記内筒と外筒23は離反方向又は引きつけ方向に付勢されている。【選択図】図2
