PROBLEM TO BE SOLVED: To obtain a structure which can regulate the axial movement of a dust cover with respect to an objective split shaft without causing a weight increase of the objective split shaft (inner shaft) which is externally fit to the dust cover.SOLUTION: The axial movement of a dust cover 9 which is externally fit to an inner shaft 10 is regulated by a stopper ring 28 which is externally supported to the inner shaft 10. The displacement of the stopper ring 28 with respect to the inner shaft 10 is prevented by a screw stop of such a form that the inner shaft 10 is gripped between a tip of a screw 30 which is screwed into a screw hole existing at one point of the stopper ring 28 in a circumferential direction, and a portion located at a side opposite to the screw hole out of the stopper ring 28 in a radial direction.SELECTED DRAWING: Figure 1
【課題】ダストカバーを外嵌した対象分割軸(インナシャフト)の重量化を招く事なく、対象分割軸に対するダストカバーの軸方向の移動を規制する事ができる構造を実現する。【解決手段】インナシャフト10に外嵌したダストカバー9の軸方向の移動を、インナシャフト10に外嵌支持したストッパリング28により規制する。インナシャフト10に対するストッパリング28の変位防止を、ストッパリング28の円周方向1箇所に存在するねじ孔に螺合されたねじ30の先端部とストッパリング28のうちねじ孔に対して径方向反対側に位置する部分との間でインナシャフト10が挟持される態様のねじ止めによって図る。【選択図】図1
