INPUT DEVICE

To provide an input device having a first axial member and a second axial member, the first and second axial members being prevented from becoming wobbly after being engaged.SOLUTION: An input device 1 includes: an axial cylinder 10 formed in the shape of a cylinder; and a tail valve 20 engaged with the axial cylinder 10 by being inserted into the inside from an insertion edge part of the axial cylinder 10. In the inner peripheral surface of the axial cylinder 10 and the outer peripheral surface of the tail valve 20, a protruding part 23 extending in the axial direction is formed in one side and a recessed part 17 is formed which opens toward the edge part to receive the protruding part 23 in the other side. The protruding part 23 and the recessed part 17 are engaged with each other when the axial cylinder 10 and the tail valve 20 are engaged with each other.SELECTED DRAWING: Figure 6 【課題】第１軸部材及び第２軸部材を有する入力装置において、第１軸部材及び第２軸部材の嵌合後のがたつきを抑制することができる入力装置を提供する。【解決手段】入力装置１が、円筒状に形成された軸筒１０と、軸筒１０の挿入端部から内部に挿入されて軸筒１０と嵌合する尾栓２０とを具備し、軸筒１０の内周面及び尾栓２０の外周面において、一方には軸線方向に延びる凸部２３が形成され、且つ、他方には凸部２３を受容するように端部に向かって開口する凹部１７が形成され、凸部２３及び凹部１７が、軸筒１０及び尾栓２０の嵌合時に嵌合するように構成されている。【選択図】図６
