PURPOSE: To facilitate the work of adjusting a through hole, formed at a fitting plate part, to a through hole formed at the supporting plate part of a housing and prevent the mutual dislocation of the through holes after adjustment. CONSTITUTION: Protruding parts 17, 17 formed at the inner peripheral surface of a fitting plate part 9 are fitted into engaging holes formed at a supporting plate part so as to adjust both through holes to each other. The inner edges 21, 21 of plural cutouts 10, 10 formed at the fitting plate part 9, and the protruding parts 17, 17 are positioned almost on the same periphery. As a result, the rigidity of the fitting plate part 9 becomes appropriate. |
