The upper end of the guide rail 15 is fastened to the inner panel 14 by using the bolt 41, and the lower end is positioned and fixed by being inserted and fitted into the receiving member 8 previously attached to the inner panel 14. Therefore, the use of the guide rail brackets 2, 4 formed by sheet metal forming using a mold having a complicated shape as in the above-described conventional apparatus is eliminated, and the guide rails can be easily formed only by simple extrusion molding or press molding. Can be manufactured. Therefore, there is an effect that the cost can be reduced accordingly, and the weight and modularization of the vehicle can be further promoted.

Although the present embodiment has been described in detail, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention, the present embodiment is not limited to this embodiment. Included in the invention. For example, in the above description, the slider 25 of the carrier plate 22 is formed so as to be slidable on one bent portion 15, but may be provided so as to slide over the other bent portion 16 as a matter of course. The large and small guides 201 and 202 are formed so as to be inserted only into the lower end of the other bent portion 16 and fitted to the guide rail 14. However, as shown in FIGS. The large guide 201 'and the small guide 202' may be formed so as to fit between the bent portions 15 and 16 (the dashes in FIG. Represents the equal part). Furthermore, although the cross-sectional shape of the both bent portions 15 and 16 is L-shaped, the cross-sectional shape may be other suitable shapes such as U-shape and U-shape. Also, stopper rubbers 207, 208, 207 ', 20
8 'instead of a coiled spring member
07, 208 and the like. Furthermore, although the receiving member 38 is attached to the inner panel 10, the receiving member may be formed integrally with the inner panel 10, and the attachment of the receiving member 38 can be omitted, so that production efficiency can be reduced. Can be further improved. In the above description, the door is a side door, but the present invention can be applied to a rear door. In the above description, a single guide rail system is used. However, the present invention can be applied to a guide rail in which two guide rails are arranged in parallel. Further, the wire 18 as a rope member is guided only by the guide grooves 191, 205, and 206 provided in the upper rope member guide 19 and the lower rope member guide 20, but a roller member may be provided in a part of these grooves. Alternatively, a roller member may be shafted without providing a guide groove, and a wire may be engaged with the roller member. According to this, the driving resistance of the motor can be reduced, which is advantageous. Further, although the guide rail 14 is formed of metal, it is needless to say that the guide rail 14 may be formed of a synthetic resin material such as reinforced plastic whose strength is reinforced with carbon fiber or the like. Further, the inner panel 10 may be formed entirely of metal or partially formed of a composite material of metal and synthetic resin.
