1. An electric device comprising:
a contact unit,
an electromagnet unit configured to drive the contact unit, and
a main body frame configured to house the contact unit and the electromagnet unit in a housing section,
wherein the main body frame includes a first frame including a flexible protruding plate portion protruding from an open end side,
wherein a first direction and a second direction and a third direction are orthogonal to each other, wherein the flexible protruding plate portion is arranged on each of two side walls of the first frame, the two side walls being located on opposite sides of each other in the third direction,
a second frame facing the first frame in the first direction to form the housing section, and
a snap-fit mechanism configured to connect the first frame to the second frame, the snap-fit mechanism including
a fitted portion provided on the flexible protruding plate portion and
a fitting projection portion provided on a side wall of the second frame and fitting with the fitted portion,
in which the fitted portion and the fitting projection portion are fitted by bringing the first frame and the second frame into relative proximity in the first direction, and the fitting is released by relatively displacing the first frame and the second frame in the second direction orthogonal to the first direction and to the third direction.
