Abstract:

To easily absorb a fluctuation in the inside diameter of a through-hole while securing a filler supporting function, concurrently with the facilitation of an operation of attachment into the through-hole.

An locking portion A2, which can be locked to a peripheral edge of an opening of the through-hole H of a structure F, is provided in each of a plurality of annular-direction locations of an openable/closable retaining portion A1 which is formed in such an approximately annular shape as to be capable of receiving a filler in a position to make an entry into an annular space S between the through-hole H formed in the structure F and a long body C inserted into the through-hole H, and where one annular-direction location thereof serves as a free end 1a. The outer peripheral edge, on the side of the free end 1a, of the receiving portion A1 is formed in such a shape as to be biased radially inward with respect to outer peripheral edges of other portions.
