The present invention relates to a device for unwinding a wire of a spare tire carrier and preventing the wire from being reversely wound which prevents a wire of a spare tire carrier from being reversely wound after the wire is completely unwound by using a stopper which is linearly moved according to a rotating direction of a spiral shaft interlocked with a wire winding drum. The present invention includes a drum housing unit mounted on the underside of a vehicle; a wire winding drum which is inserted into the drum housing unit and supported to be rotated; an operating shaft for attaching/detaching a tire which is supported by the drum housing unit to be rotated and which rotates and reversely rotates the wire winding drum according to a rotating direction; a tire carrier wire which is unwound and wound from/on the wire winding drum according to the rotating direction of the operating shaft and which enables the attachment/detachment of the tire; a spiral shaft for sensing the rotation on which a spiral groove having preset pitches partially on the outer circumference; and a stopper for controlling the number of rotation which advances and retreats in a straight direction according to the rotating direction of the spiral shaft for sensing the rotation and of which one end is positioned inside the spiral groove; and a stopper guide which is fixed to the drum housing unit and which guides the linear movement of the stopper for controlling the number of the rotation. |
