An attaching portion (12) includes resiliently deformable holding pieces (24), each of which has a pressing portion (26). A clearance between pressing portions (23, 26) is less than the thickness of a bracket (B) in a free state where the holding pieces (24) are not deformed. The holding pieces (24) are deformed to widen the clearance between the pressing portions (23, 26) in the process of inserting the bracket (B) between the pressing portions (23, 26). Thus, insertion resistance does not become excessive. The bracket (B) is sandwiched between the pressing portions (23, 26) by resilient forces of the holding pieces (24) with the attaching portion (12) attached to the bracket (B). Therefore, the attaching portion (12) and the bracket (B) do not shake relative to each other.
