## Abstract

According to one embodiment, an attachment/detachment mechanism detachably fixes an insertion member and an outer sheath member. The mechanism includes a removal preventing member and a rotation preventing member. The removal preventing member is configured to restrict movement of the insertion member inserted in the outer sheath member relative thereto in a removing direction. The rotation preventing member is configured to restrict movement of the insertion member inserted in the outer sheath member relative thereto in a rotating direction.

## Claims

### Claim 1

An attachment/detachment mechanism which detachably fixes an insertion member inserted in an outer sheath member thereto, the mechanism comprising:
a removal preventing member configured to restrict movement of the insertion member in the outer sheath member relative thereto in a removing direction; and
a rotation preventing member configured to restrict movement of the insertion member in the outer sheath member relative thereto in a rotating direction.
