A yoke housing accommodates an armature having a coil and has a tubular circumferential wall. The yoke housing includes a plurality of pieces, which form the yoke housing, and a fracture portion, which is located along a boundary between the pieces. The fracture portion fractures when a compression force is applied from the outside to break the yoke housing into the pieces.
