For this reason, compared with the conventional window regulator apparatus, the stress concentration to a junction part (bracket) can be prevented.

  According to another aspect of the window regulator apparatus of the present invention, there is provided rotational torque transmitting means for transmitting the rotational torque generated by the electric motor to the drum, and the drum receives the rotational torque transmitted by the rotational torque transmitting means and moves the carrier plate to the guide rail. Is moved to one end side or the other end side.

  In the window regulator device according to the third aspect, the first and second brackets are integrally formed. According to this configuration, the number of parts and the number of assembly steps of the window regulator device can be reduced as compared with the case where the first and second brackets are molded separately. For this reason, the manufacturing cost of a window regulator apparatus can be reduced.

  In the window regulator device according to claim 4, the total length of the protrusion is longer than the diameter of the inner cable guide member, the side opposite to the joint surface of the protrusion is formed to be inclined, and the fixing surface is formed from the end of the side. It is formed to extend on the opposite side to the joint surface. According to this configuration, the protruding portion becomes a step with respect to the joint surface, and it is possible to reliably prevent the inner cable from being detached from the inner cable guide member.

As shown in FIGS. 1 and 2, the window regulator device 10 includes a rectangular guide rail 11 that is bent in a bow shape up and down, an inner cable 12 that is routed in a loop shape, and a pulley around which the inner cable 12 is wound. 13 (inner cable guide member), a carrier plate 14 slidably held along the longitudinal direction of the guide rail 11, and a housing fixed to the other end 11b of the guide rail. A substantially cylindrical drum 15 around which the cable 12 is wound, a rotational torque transmitting means 16 for transmitting the rotational torque generated by the electric motor M to the drum 15, and a bracket 17 joined to the one end 11a of the guide rail are provided. is doing.

  As shown in FIGS. 3 and 4, the bracket 17 includes a first bracket 17a and a second bracket 17b. In this example, the first bracket 17a and the second bracket 17b are integrally formed. According to this configuration, the number of parts and the number of assembly steps of the window regulator device can be reduced as compared with the case where the first and second brackets are molded separately. For this reason, the manufacturing cost of a window regulator apparatus can be reduced.

  The first bracket 17a is formed with a protruding piece 17c for fixing to the door panel, a joining surface 17d to which one end 11a of the guide rail is joined, and a joining surface 17e to which the pulley 13 is joined. The second bracket 17b includes a protruding portion 17g protruding from the end of the bonding surface 17e opposite to the bonding surface 17d, a door panel fixing portion 17f, and a guide portion (not shown) for guiding the inner cable 12 to the pulley 13. ) Is formed. The side of the projecting portion 17g opposite to the joint surface 17e is inclined. For example, the total length of the protrusion 17g may be set longer than the diameter of the pulley 13. According to this configuration, it is possible to reliably prevent the protruding portion 17g from becoming a step with respect to the joint surface 17e and the inner cable 12 from being detached from the pulley 13.

As shown in the figure, a vehicle door 1 includes a door body 1a (FIG. 5) and a frame 1b (see FIG. 5) attached to the door body 1a so as to form an opening 1c (FIG. 5) in the upper part of the door body 1a. 5) and a door panel 1d (FIG. 6). The window glass 2 of the vehicle is held by the frame 1b so as to be movable up and down in order to open and close the opening 1c. A window regulator device 10 that moves the window glass 2 up and down is disposed inside the door 1. The carrier plate 14 is disposed on the facing surface 11c (FIG. 6) facing the window glass 2 of the guide rail 11, and is fixed to the lower end 2a of the window glass. The drum 15 is fixed to the door panel 1d through a housing fixed to the other end 11b of the guide rail.

  The first bracket 17a is directly fixed to the door panel 1d by screwing with a nut member (not shown) via a protruding piece 17c (FIG. 3) provided at a position facing the door panel 1d. In this example, the door panel fixing portion 17f (FIG. 3) of the second bracket 17b is formed to protrude toward the window glass 2 from the joint surface 17e (FIG. 3) to which the pulley 13 is joined. The second bracket 17b is indirectly fixed to the door panel 1d by screwing with a nut member (not shown) via the door panel fixing portion 17f (FIG. 3). In this state, the carrier plate 14 slides along the opposing surface 11 c of the guide rail when the rotational torque is transmitted to the drum 15 by the rotational torque transmitting means 16. By this sliding, the window glass 2 moves up and down toward the one end 11a side of the guide rail or the other end 11b side of the guide rail, and the opening 1c of the door opens and closes.

  In this way, the first bracket 17a is fixed to the one end and the other end of the door panel 1d by the protruding piece 17c and the second bracket 17b by the door panel fixing portion 17f. Therefore, the stress generated in the bracket 17 when the door 1 is closed or the window glass 2 is moved up and down can be distributed to the first bracket 17a and the second bracket 17b. For this reason, compared with the conventional window regulator apparatus, stress concentration on the bracket 17 can be prevented.

  In the present embodiment, the example in which the rotational torque generated by the electric motor M is transmitted to the drum 15 by the rotational torque transmitting means 16 has been described. The present embodiment is not limited to this. For example, a configuration in which rotational torque generated by manual operation is transmitted to the drum 15 may be employed.

  Note that the drum 15 may be rotatably held in a housing fixed on a bracket fixed to the other end 11b of the guide rail integrally or separately through fixing means. According to this configuration, the present invention can be applied to a conventional window regulator device in which the drum 15 is located at a position different from the guide rail 11.
