1. An electronic apparatus chassis comprising:
a first chassis member having a substantially rectangular plate shape;
a second chassis member connected to the first chassis member in an attachable and detachable manner;
a first screw configured to fasten one first edge portion of a pair of edge portions of the first chassis member in a width direction to the second chassis member, and a second screw configured to fasten a second edge portion to the second chassis member;
a third screw configured as a falling prevention screw in the first chassis member and configured to fasten the first chassis member to the second chassis member at a position between the first screw and the second screw based on the width direction;
a first screw hole into which the first screw is screwed, a second screw hole into which the second screw is screwed, and a third screw hole into which the third screw is screwed, all of which holes are in the second chassis member;
a first engagement piece in an inner surface of the first edge portion of the first chassis member and which has a first claw portion protruding toward an outside of the first edge portion;
a second engagement piece in an inner surface of the second edge portion of the first chassis member and which has a second claw portion protruding toward an outside of the second edge portion; and
a first receiving portion in the second chassis member and whereat the first engagement piece is engaged and disengaged, and a second receiving portion whereat the second engagement piece is engaged and disengaged,
wherein the first chassis member and the second chassis member are configured so that their relative positions are not substantially changed when the first screw and the second screw are loosened and removed from the first screw hole and the second screw hole, and are further configured so that their relative movement is in a direction away from each other when the third screw is loosened and removed from the third screw hole.
