Abstract: An electronic device unit includes a frame member, a first board that is retained so as to be capable of moving with respect to the frame member in a horizontal direction of the frame member within a range restricted by a movement restricting portion, a first connector provided to the first board, a second board that faces the first board in the horizontal direction and that is positioned with respect to and fixed to the frame member; and a second connector that is provided to the second board and that is connected to the first connector in the fixed state of the second board.

Abstract: The removing jig includes a frame member and an arm member. The arm member includes a pair of side plates each provided with an axial hole. The arm member further includes an engagement portion that engages with the lever portion at its tip. The frame member includes a contact portion that contacts with a back surface of the connector body, a pair of side frame plates each provided with a guide groove formed with respect to the axial hole, and a first window portion from which the engagement portion protrudes.
