Two different types of fitting holding parts, a first holding part and a second holding part, were formed in the fitting holding part as the ones acting and holding on the peripheral surface of the buttock end of the hand side casing.
Of these two types of holding parts, the first holding part is formed with a narrow width along the circumferential direction and a high height along the radial direction. Yes. Accordingly, if the peripheral surface diameter of the proximal housing is larger than the predetermined peripheral surface diameter, the first holding portion can contact the buttock end portion without falling down on the tip portion. . On the other hand, if the diameter is different from the predetermined peripheral surface diameter, the first holding portion is deformed into a sideways posture and can be contacted in a posture along the buttock end.
Even if the height of the first holding portion is reduced due to wear, the second holding portion can come into contact with the peripheral surface of the butt end portion of the proximal housing, and the first holding portion and the second holding portion And the contact force with the peripheral surface of the proximal housing can maintain the fitting force.
Furthermore, when the wear damage of the first holding portion proceeds, the fitting force can be exerted only by the second holding portion, and it is possible to prevent problems due to wear damage or the like occurring in the first holding portion having a high height.
