Abstract
A nut () includes a main portion (A) formed with a bolt insertion hole (), into which a bolt is insertable, and a wedge portion (B) projecting from the main portion (A) in a radially outward direction of the bolt insertion hole () and having a width smaller than that of the main portion (A). Thus, parts (B) extending lateral to the wedge portion (B) in parallel with a projecting direction of the wedge portion (B) can be made thicker than parts (A) extending lateral to the main portion (A). Therefore, the parts (B) that resist an accompanying rotation of the nut () can be thickened without enlarging a housing (), with the result that strength against the accompanying rotation of the nut () can be ensured.
