[0067] The guide rail 1 is connected to the vehicle body (not shown) by brackets 20 and 21. It is attached to the inner panel of the door.

[0068] Next, the operation of this embodiment will be explained.

[0069] First, the window glass 49 is closed with respect to the guide rail 1 shown in FIG. From the current position, turn the motor M on to the switch on the driver's seat or the side door switch on the vehicle body. When driven by the switch, the motor shaft 98 of the motor M is magnetically attached to the case 97. At the same time, the through hole 10 of the motor shaft 98 is rotated by the motor shaft 98 and the rotor 103. The female threaded portion 101 of the geared cable 5 rotates while engaging with the protrusion 51 of the geared cable 5, and As the motor shaft 98 of the motor M rotates, the cable 5 is attached to the annular shape of the first pulley 6. While engaging the groove 64 and the annular groove 85 of the second pulley 7, the outer tube 17, 19 and the front part of the slider plate 14 along the longitudinal direction of the guide rail 1. and move in the direction of arrow a in FIG.

[0070] The length of the guide rail 1 due to the rotation of the motor shaft 98 of the motor M of the geared cable 5 Due to the movement in the hand direction, the first pulley 6 moves as the geared cable 5 moves. Rotate counterclockwise in FIG. 1 about the support pin 11 with respect to the holder plate 10. At the same time, the second pulley 7 moves the holder plate as the geared cable 5 moves. The gear dock rotates counterclockwise in Fig. 1 with respect to the support pin 13 as an axis relative to the The other end of the cable 5 connects the carrier plate 2 to the guide rail 1 via the locking ring 53. the carrier plate 2 is guided by the other end of the geared cable 5. The window glass 49 moves downward along the longitudinal direction of the idle rail 1, and the window glass 49 is moved downward along the longitudinal direction of the idle rail 1. As shown in FIG. descend.

[0071] downward direction of the carrier plate 2 with respect to the guide rail 1 by the geared cable 5 37, the lower edge of the carrier plate 2 is moved by the elastic body 78, as shown in FIG. The stopper piece 77 of the lower bracket 4 touches the guide rail of the carrier plate 2. The carrier plate 2 prevents the second pulley 7 from moving downward relative to the pulley 1. The locking hole 8 of the base body 28 of the carrier plate 2 is in front of the second pulley 7. located on the opposite side.

[0072] In addition, when the window glass 49 is lowered relative to the guide rail 1 shown in FIG. From the released position, turn the motor M on to the driver's seat switch or the side door switch of the vehicle. When the motor shaft 98 of the motor M is driven in reverse by the switch, the motor shaft 98 of the motor M is rotated to the case 97. The magnet 102 and rotor 103 rotate the motor shaft at the same time. The female threaded portion 101 of the through hole 100 of 98 meshes with the protrusion 51 of the geared cable 5. The geared cable 5 rotates as the motor shaft 98 of the motor M rotates. while engaging the annular groove 64 of the second pulley 6 and the annular groove 85 of the second pulley 7. - The inside of the tubes 17, 19 and the front part of the slider plate 14 are connected to the guide rail 1. 37 along the longitudinal direction in the direction of arrow b in FIG.

[0073] The length of the guide rail 1 due to the rotation of the motor shaft 98 of the motor M of the geared cable 5 Due to the movement in the hand direction, the first pulley 6 moves as the geared cable 5 moves. Rotate clockwise in FIG. 37 about the support pin 11 with respect to the holder plate 10. At the same time, the second pulley 7 moves the holder plate as the geared cable 5 moves. The gear dock rotates clockwise in Fig. 37 with respect to the support pin 13 as an axis. Attach the carrier plate 2 to the guide rail 1 via one end of the cable 5 or the locking ring 52. Pull it upward so that the carrier plate 2 is guided by one end of the geared cable 5. The window glass 49 is moved upward along the longitudinal direction of the idle rail 1 to the position shown in FIG. As shown, it rises along the longitudinal direction of the guide rail 1 together with the carrier plate 2. do.

[0074] Upward movement of the carrier plate 2 with respect to the guide rail 1 by the geared cable 5 As a result of the movement, a part of the first pulley 6 moves toward the carrier plate The first pulley 6 enters the housing portion 29 of the base body 28 of the second carrier plate 2, and the first pulley 6 The carrier plate 2 prevents upward movement relative to the guide rail 1, and the carrier plate 2 The locking hole 9 of the support wall 33 of the base 28 of the carrier plate 2 overlaps the front of the carrier plate 2. is located on the side of the first pulley 6.

[0075] Note that there is a female thread on the end of the motor shaft of the motor that screws into the protrusion of the geared cable. It is also possible to integrally provide a nut having the same.

[0076]

[Effect of the idea]

As described above, according to the window regulator of the present invention, the drive means is By moving the geared cable, the first pulley and the geared cable are driven by the driving means. Moves up and down along the length of the guide rail while engaging the second pulley. Therefore, as the geared cable moves, the first pulley and the second pulley move Rotates relative to the support and the second support, and the carrier plate attaches to the geared cable. Move the window glass up and down along the length of the guide rail, and then It can be moved up and down along the longitudinal direction of the guide rail together with the rear plate.

[0077] In addition, the geared cable of the carrier plate should be used vertically with respect to the guide rail. When moving in the direction, the first locking part of the carrier plate is positioned in front of the second pulley. Since the second locking part of the carrier plate is located on the side of the first pulley, The first locking part and the second locking part of the carrier plate are connected to the first pulley and the second pulley. The carrier plate can be moved between the first pulley and the second pulley without contacting the carrier plate. Can be stacked on the pulley, the total length of the guide rail does not increase, and the first pulley prevents the carrier plate from moving upward relative to the guide rail, and The slider prevents the carrier plate from moving downwards relative to the guide rail. The movement of the carrier plate relative to the guide rail by the geared cable is controlled by the first pulley. This can be prevented by a second pulley and a second pulley, unlike the conventional There is no need to provide a stopper at the end to prevent movement of the carrier plate.
