CONSTITUTION:A stem part 3 is formed into a hollow shape, and its outside is provided with U-shaped slits 14, 18 to form flexible pieces 15, 19. In attaching an attaching member 6 to an attached plate member 8, when the tip of the stem part 3 is inserted into the attaching hole 8a of the attached plate member 8, the inclined face 16 of a locking projection 20b of the flexible piece 19 comes into contact with the attaching hole 8a. The flexible piece 19 is therefore pushed toward the axial center of the stem part 3 for its elastic deformation, and the projection 20b can thereby pass through the attaching hole 8a. When the stem part 3 is continuously inserted, locking projections 17, 20a pass through the attaching hole 8a similarly to the above case, and the upper part of the locking projection 20a is finally locked in the attaching hole 8a. In the case where a distance W1 between the attaching member 6 and the attached member 8 is long, the locking projections 17, 20b are severally locked in the attaching hole 8a.
