To prevent slipping-out of a rear plate by surely supporting a rear end part of a drawer when forcibly pushing the drawer in a box body for the drawer from a front opening.

The box body 3a for the drawer is constituted so that a screw tool 6 inserted from a rear surface of the rear plate 5b by butting a rear end surface of right-left side plates 5c and 5d against both end parts of a front face of the rear plate 5b, is fixed to the right-left side plates 5c and 5d, and both end parts of a rear surface of a front plate 5a shorter in the vertical length than the rear plate 5b and the right-left side plates 5c and 5d are butted against an upper part of a front end surface of the right-left side plates 5c and 5d, and the screw tool 6 inserted from the front surface side of the front plate 5a is fixed to the right-left side plates 5c and 5d. A drawer stopper 7 is arranged in a corner part formed of the rear plate 5b and the right-left side plates 5c and 5d, and the drawer stopper 7 is fixed to the right-left side plates 5c and 5d by a screw 8. A rear end part of the drawer 4 is freely allowed to abut on the drawer stopper 7.
