A gear housing 7 is formed integrally with one of the brackets 2, and a worm 8 and a worm wheel 9 that mesh with each other are provided in the gear housing 7. The worm wheel 9 is connected to one end of the winding drum 3, and the worm 8 is connected to an electric motor (not shown). When the electric motor is rotated in a specific direction by the on-vehicle battery, the winding drum 3 is rotated via the worm 8 and the worm wheel 9. As a result, the wire 6 is wound around the winding unit 4 or is sent out from the winding unit 4.

As shown in FIGS. 1 and 2, a disc-shaped side case portion 10 is integrally formed on each of the brackets 1 and 2, and each side case portion 10 guides the guide plate 5 of the winding drum 3 to the left and right sides. It is arranged to be fitted from. A fixed cover 11 made of a synthetic resin plate is stretched between the lower front sides of both side case portions 10, and a metal protection bar 12 is interposed between the upper sides of the fixed covers 11. The protection bar 12 plays a role of maintaining a predetermined space between the side case portions 10. Further, the fixed cover 11 has a hook accommodating portion.
A hook formed with 13 and fixed to the tip of the wire 6.
It is supposed to accommodate 14.

As shown in FIGS. 1 and 4, annular guide grooves centering on the winding drum 3 are formed on the surfaces of the side case portions 10 which face each other.
