Abstract
Either the base part or the coupling part includes a first coupling member which is substantially circular in cross-section in a radial direction perpendicular to the central axis and has a diameter of a first length, while the other of the base part and the coupling part includes a first holding member which, with its inner circumferential surface having a substantially circular shape in cross-section in the radial direction, holds the first coupling member so as to surround its outer circumferential surface. The inner circumferential surface of the first holding member is partially opened in the radial direction, and an opening width of an opening part of the first holding member, which is elastically deformable, is narrower than the first length.
