Electric device with a main body frame including a snap-fit mechanism

An electric device comprising:

• a first frame and a second frame configured to house an electric component by connecting respective open end sides of the first and second frames facing each other in one direction, the first frame including a flexible protruding plate portion protruding from the 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;
• 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;
• and
• a relative displacement suppression mechanism configured to suppress relative displacement between the connected first and second frames,
• wherein the relative displacement suppression mechanism includes a first fixing portion provided on a side wall of the first frame, a second fixing portion provided on a side wall of the second frame to overlap with the first fixing portion in the one direction, and a fixed member movable over the first fixing portion and the second fixing portion, the fixed member sliding in a direction in which the first fixing portion and the second fixing portion are arranged.
