A successive screw feeder driver includes a grip handle, a rotating mechanism provided on the upper side of the grip handle, a screw driving bit attached removably to the front portion of the rotating mechanism, a reduction mechanism formed above the rotating mechanism and a drive unit for rotating the bit. The drive unit is connected to the reduction mechanism and is positioned behind and above the grip handle. A screw feed mechanism body is mounted on the front portion of the grip handle and is slidable in the longitudinal direction with the bit being inserted rotatably into the screw feed mechanism body. A supporting and pushing portion extends from the upper portion of the rear end of the grip handle to a lower surface of the housing for the drive unit beyond the position where a virtual rotation line extending rearward of the axis of the bit is formed. A screw feed mechanism is provided in the screw feed mechanism body for feeding screws successively to a screw driving position. The screws are carried on a screw chain side by side in a belt-like arrangement.
