Claim:
A housing assembly, comprising: a nut that has a main portion with a bolt insertion hole extending along an axial direction and configured for receiving a bolt, the main portion having opposite parallel side surfaces aligned substantially parallel to the axial direction of the bolt hole and being spaced apart by a width dimension and a wedge projecting from the main portion in direction aligned radially to the bolt insertion hole and normal to the width direction of the main portion the wedge having opposite parallel side surfaces spaced inward from the side surfaces of the main portion and defining a constant width dimension narrower than the width dimension of the main portion; and a housing with a nut accommodating portion, the nut accommodating portion having a bottom wall and opposed side walls extending up from the bottom wall to define opposed substantially parallel main side wall portions disposed for engaging the opposite side surfaces of the main portion of the nut and opposed substantially parallel wedge side wall portions disposed for engaging opposite side surfaces of the wedge, the wedge side wall portions of the side walls being thicker than the main side wall portions for preventing an accompanying rotation of the nut.
