  Here, the window regulator apparatus 20 drives the window glass 12 downward by opening an operation switch (not shown) installed on the vehicle interior side of the side door 10, for example, and closes the operation switch. Thus, the window glass 12 is driven up.

  The window regulator device 20 includes a drive motor 30, a carrier plate 40, first and second guide rails 50 and 60, and first and second stays 70 and 80. An external connector (not shown) on the vehicle side is electrically connected to the drive motor 30 via a connector connection CN shown in FIG. As a result, a drive current from an in-vehicle battery (not shown) or the like is supplied to the drive motor 30 in accordance with the operation of the operation switch, and the window glass 12 is driven downward or upward.

  The drive motor 30 includes a motor unit 31 and a gear unit 32. A rotation shaft (not shown) that rotates forward or backward by supplying a drive current is rotatably provided inside the motor unit 31. A worm (not shown) as a speed reduction mechanism is integrally provided on the distal end side of the rotating shaft, and the worm is disposed inside the gear portion 32. A worm wheel WH (see FIG. 7) that meshes with the worm of the rotating shaft is rotatably provided inside the gear portion 32. Here, the worm and the worm wheel WH form a speed reduction mechanism, and a drive motor Reference numeral 30 denotes a motor with a speed reduction mechanism.

  As shown in FIG. 3, a cylindrical drum 35 around which one end side of the open side cable 33 and the closed side cable 34 is wound is disposed outside the gear portion 32. A spiral groove 35a (see FIG. 7) is formed around the drum 35, and one end side of the open side cable 33 and the close side cable 34 is wound around the spiral groove 35a a plurality of times. The drum 35 is rotatably accommodated in a drum case 36 fixed to the gear portion 32, and the torque of the worm wheel WH having a high torque is transmitted to the drum 35. .

  Here, as shown in FIG. 7, a notch hole 36a extending in the axial direction of the drum 35 is formed in the drum case 36, and the open side cable 33 and the close side cable 34 are connected via the notch hole 36a. One end side enters and exits the drum case 36.

  Although not shown, a plurality of meat stealing portions (recesses) are formed on the surface portion 41 of the carrier plate 40. Thereby, the weight reduction of the carrier plate 40 is realized, and the deterioration of the molding accuracy due to the “sink phenomenon” that occurs when the molten resin is cured is prevented.

  As shown in FIGS. 7 and 9, a first sliding portion 46 and a second sliding portion 47 are integrally provided on the back surface portion 42 of the carrier plate 40. These first and second sliding portions 46 and 47 are formed in a substantially rectangular shape in plan view as shown in FIG. 9, and are provided so as to protrude in the vertical direction with respect to the back surface portion 42. And the cross section along the longitudinal direction of the 1st, 2nd sliding parts 46 and 47 and the cross section along a transversal direction are respectively substantially the shape where the front end side was formed in the predetermined | prescribed radial dimension, as shown in FIG. 11 and FIG. It is formed in an arc shape. Note that since the projected shapes of the first and second sliding portions 46 and 47 viewed from the direction shown in FIG. 11 are the same, only the first sliding portion 46 appears in FIG.

  As shown in FIG. 11, the other end side of the open side cable 33 and the close side cable 34 is attached to the first sliding portion 46. As shown in FIG. 9, cable introduction holes 46 a and 46 b are respectively formed on both sides in the longitudinal direction of the first sliding portion 46, and the open-side cable 33 is connected via these cable introduction holes 46 a and 46 b. The other end of the closed cable 34 is guided into the first sliding portion 46. Thus, the open side cable 33 and the close side cable 34 are connected to the carrier plate 40.

  As shown in FIG. 11, the inside of the first sliding portion 46 has a two-story structure. A first tensioner 48a and a second tensioner 48b are accommodated in the first gap 46c at the lower side in the drawing and the second gap 46d at the upper side in the drawing, respectively. These first and second tensioners 48a and 48b are formed by coil springs, respectively, so as to remove the slack of the open side cable 33 and the close side cable 34.

  Here, the first sliding portion 46 is configured to be connected to the other ends of the open-side cable 33 and the closed-side cable 34 as described above, but the second sliding portion 47 has a cable introduction hole 46a. , 46b and the first and second gaps 46c, 46d are not formed. The first sliding portion 46 comes into sliding contact with the first guide groove 51 of the first guide rail 50, and the second sliding portion 47 comes into sliding contact with the second guide groove 61 of the second guide rail 60. ing.

  As shown in FIG. 9, on the back surface portion 42 of the carrier plate 40, three first drop-off preventing claws 49a are integrally provided between the first sliding portion 46 and the lower glass fixing hole 44 in the drawing. ing. These first drop prevention claws 49 a are provided at substantially equal intervals along the longitudinal direction of the first sliding portion 46, and are disposed close to the first sliding portion 46.

  On the other hand, on the back surface portion 42 of the carrier plate 40, one second drop prevention claw 49b is integrally provided between the second sliding portion 47 and the upper glass fixing hole 44 in the drawing. The second drop prevention claw 49 b is provided at a substantially intermediate portion along the longitudinal direction of the second sliding portion 47, and is disposed close to the second sliding portion 47.

  Each first drop prevention claw 49a and second drop prevention claw 49b prevent the first sliding portion 46 from falling off the first guide groove 51 and the second sliding portion 47 from falling off from the second guide groove 61. It has a function to do. Specifically, in each of the first drop-off prevention claw 49a and the second drop-off prevention claw 49b, the first sliding portion 46 is inside the first guide groove 51, and the second sliding portion 47 is the second guide groove 61. The back side of the first flange portion 52 of the first guide rail 50 and the second flange portion 62 of the second guide rail 60, that is, the first and second guide grooves 51 and 61 side, It comes in sliding contact with the opposite side.

  Here, three first drop prevention claws 49a corresponding to the first sliding portion 46 are provided. This is because the first sliding portion 46 is pulled by the open-side cable 33 and the closed-side cable 34, so that rattling of the first sliding portion 46 with respect to the first guide rail 50 is suppressed. That is, by providing the three first drop-off prevention claws 49a over substantially the entire region along the longitudinal direction of the first sliding portion 46, the occurrence of the twisting of the first sliding portion 46 with respect to the first guide rail 50 is suppressed. To ensure smooth operation.

  On the other hand, since the second sliding portion 47 only moves following the first sliding portion 46, it is sufficient to provide only one second drop-off preventing claw 49b. However, three second drop prevention claws 49b can be provided similarly to the first sliding portion 46 side, but by increasing the second drop prevention claws 49b, sliding with the second guide rail 60 is possible. The contact part will increase. Accordingly, although the rattling of the carrier plate 40 can be further suppressed, the smooth sliding of the second sliding portion 47 may be hindered, and the second drop-off preventing claw 49b may be prevented depending on the specifications of the window regulator device 20. Set the number.

  As shown in FIGS. 2 to 4, the carrier plate 40 slides along the extending direction of the first and second guide rails 50 and 60. That is, the first and second guide rails 50 and 60 guide the raising and lowering of the carrier plate 40. The first and second guide rails 50 and 60 are provided side by side so as to be parallel to each other. The first and second guide rails 50 and 60 are formed in a rod shape by pressing a steel plate, and the first and second guide rails 50 and 60 are formed in a substantially arc shape in cross section along the short direction. ing. The first and second guide rails 50 and 60 include a first guide groove 51 and a second guide groove 61, and the cross sections of the first and second guide grooves 51 and 61 are substantially arc-shaped in the entire longitudinal direction. It has become.

  As shown in FIG. 7, the radial dimensions of the first and second guide grooves 51 and 61 are larger than the radial dimensions of the first and second sliding portions 46 and 47 on the tip side along the short direction. Set to dimensions. Thereby, a minute gap S (only the first guide groove 51 side is shown in the drawing) is formed between the first and second guide grooves 51 and 61 and the first and second sliding portions 46 and 47. Is done. Therefore, it is possible to suppress an increase in the sliding resistance of the first and second sliding portions 46 and 47 with respect to the first and second guide grooves 51 and 61, and the operation of the window regulator device 20 can be performed smoothly. I can do it.

  Moreover, as shown in FIG. 11, since the cross-sectional shape along the longitudinal direction of the 1st, 2nd sliding parts 46 and 47 is also formed in the substantially circular arc shape, also by this, the 1st, 2nd guide groove 51 is also formed. , 61 is restrained from increasing in sliding resistance of the first and second sliding portions 46, 47.

  The first and second guide rails 50 and 60 are curved with a predetermined radius of curvature so that a substantially central portion along the longitudinal direction swells toward the first and second guide grooves 51 and 61. Thereby, the window glass 12 (refer FIG. 1) provided in the door frame 11 so that it may incline at a predetermined angle can be moved up and down smoothly. Here, the curvature radii of the first and second guide rails 50 and 60 are set according to the vehicle on which the wind regulator device 20 is mounted.

  Here, the first and second guide rails 50, 60 have a substantially arc shape in cross section along the short direction, and further, the first and second guide rails 50, 60 are bent on both sides. Two flange portions 52 and 62 are formed. Therefore, the shape of the first and second guide rails 50 and 60 is configured to function as a reinforcing rib. That is, the first and second guide rails 50 and 60 are formed into rod shapes by pressing a steel plate or the like to reduce the weight, but sufficient strength as a skeleton forming component of the window regulator device 20 is maintained. I'm leaning.

  As shown in FIGS. 1, 2, and 4, first and second stays 70 and 80 are provided at both longitudinal ends of the first and second guide rails 50 and 60, respectively. These first and second stays 70 and 80 maintain a constant distance between the first and second guide rails 50 and 60 and, like the first and second guide rails 50 and 60, are window regulators. It is a skeleton forming component of the device 20.

  The first stay 70 is formed in a predetermined shape by pressing a steel plate or the like, and a pair of stay main bodies 71 having a substantially U-shaped cross section and a pair of stay main bodies 71 provided integrally on both sides in the longitudinal direction. Mounting arm 72. The first stay 70 is disposed on one end side in the longitudinal direction of the first and second guide rails 50, 60, specifically on the upper side (see FIG. 1) of the side door 10.

A pulley 73 as a direction changing member is rotatably provided at a portion of the stay main body 71 near the first guide rail 50. The pulley 73 changes the direction of the closed cable 34 extended from the drum 35 of the drive motor 30 by approximately 180 °, and the changed closed cable 34 is moved into the first guide groove 51 of the first guide rail 50. Leading to. The other end of the closed cable 34 guided to the first guide groove 51 is guided to the cable introduction hole 46b (see FIG. 9) of the carrier plate 40.

  Each attachment arm 72 of the first stay 70 is provided with a fixing member 74 made of a nut or the like. The fixing member 74 is firmly fixed to each mounting arm 72 by fixing means such as welding. Thereby, the window regulator apparatus 20 can be fixed inside the side door 10 with a fixing bolt or the like (not shown).

  The second stay 80 is formed into a predetermined shape by injection molding or the like of a resin material such as plastic. The second stay 80 is integrally provided on the both sides in the longitudinal direction of the main body 81 and the main body 81. And a pair of rail fixing portions 82 that are thicker than each other. The second stay 80 is disposed on the other end side in the longitudinal direction of the first and second guide rails 50, 60, specifically on the lower side of the side door 10 (see FIG. 1).

  Each of the pair of rail fixing portions 82 is provided with a retaining claw 83, and each retaining claw 83 presses the other end in the longitudinal direction of the first and second guide rails 50, 60. Yes. As a result, the first and second guide rails 50, 60 are pressed against the rail fixing portions 82 and inserted into the rail fixing portions 82, so that they are prevented from being detached by the retaining claws 83.

  A cable guide 84 as a direction changing member is integrally provided between the first guide rail 50 and the second guide rail 60 of the main body 81 and near the first guide rail 50. The cable guide 84 is formed in a substantially semicircular shape with substantially the same thickness as each rail fixing portion 82, and a cable groove 84 a in which the open cable 33 enters and slides is provided around the cable guide 84. Yes.

  Here, as shown in FIG. 8, the cable groove 84 a on the second guide rail 60 side (the left side in the drawing) that guides the open cable 33 connected to the drum 35 among the cable grooves 84 a is formed on the main body portion 81.

That is, the cable groove 84a is provided in the cable guide 84 so as to be inclined. As a result, as shown in FIG. 7, the open-side cable 33 can be smoothly slid between the drum 35 and the carrier plate 40 that may cause a difference in height.

  A first gap 85 and a second gap 86 are formed between the cable guide 84 along the longitudinal direction of the second stay 80 and each rail fixing portion 82. Here, the first gap 85 on the first guide rail 50 side is set to be narrower than the second gap 86 on the second guide rail 60 side. In other words, the center of the cable guide 84 is disposed close to the first guide rail 50. Thus, by providing the first and second gaps 85 and 86, the open side cable 33 can be easily attached to the cable groove 84a when the window regulator device 20 is assembled.

  The first gap 85 is opposed to the first guide groove 51 of the first guide rail 50. As a result, the cable guide 84 changes the direction of the open side cable 33 extended from the drum 35 of the drive motor 30 by approximately 180 °, and the direction-changed open side cable 33 is changed to the first guide of the first guide rail 50. It leads into the groove 51. The other end side of the open cable 33 guided to the first guide groove 51 is guided to a cable introduction hole 46a (see FIG. 9) of the carrier plate 40.

  Thus, the cable guide 84 of the second stay 80 and the pulley 73 of the first stay 70 are connected to the other end side of the open side cable 33 and the other end side of the closed side cable 34, respectively. It guides into the guide groove 51. Thus, the first guide rail 50 guides the sliding of the first sliding portion 46 of the carrier plate 40 and the sliding of the open side cable 33 and the closed side cable 34, and the second guide rail 60 is guided by the carrier plate 40. Only the sliding of the second sliding portion 47 is guided.

  As shown in FIGS. 3 and 4, an intermediate stay 90 as a connecting member is provided at a substantially central portion along the longitudinal direction of the first and second guide rails 50 and 60. The intermediate stay 90 is provided between the first and second guide rails 50 and 60, and the distance between the first and second guide rails 50 and 60 is constant similarly to the first and second stays 70 and 80. In addition to this, the portions of the first and second guide rails 50 and 60 away from the first and second stays 70 and 80 are reinforced.

  The intermediate stay 90 is formed into a predetermined shape by pressing a steel plate like the first stay 70, and both end portions thereof are firmly attached to the first and second guide rails 50, 60 by fixing means such as welding. It is fixed. A fixing member 91 made of a nut or the like is firmly fixed to a substantially central portion along the longitudinal direction of the intermediate stay 90 by a fixing means such as welding. The driving motor 30 is fixed to the fixing member 91 via a fixing bolt (not shown). As described above, the intermediate stay 90 also functions as a fixing bracket of the drive motor 30.

  Here, the drive motor 30 is fixed to the first and second guide rails 50 and 60 at three locations including the fixing member 91 by fixing bolts (not shown). The other two locations are a pair of fixing brackets 102 and 103 provided with fixing members 100 and 101 such as nuts, respectively, as shown in FIGS. The fixing brackets 102 and 103 are firmly fixed to the first and second guide rails 50 and 60 by fixing means such as welding.

  Since the intermediate stay 90 is disposed in the vicinity of the drum 35 of the drive motor 30, it is an obstacle to the routing of the open-side cable 33 from the drum 35 to the cable guide 84. For this reason, the intermediate stay 90 is provided with an avoiding portion 92 for avoiding contact (interference) between the intermediate stay 90 and the open cable 33. The avoidance portion 92 is a relief recess having a substantially U-shaped cross section, and is formed at the same time as the intermediate stay 90 is pressed. Accordingly, contact between the intermediate stay 90 and the open side cable 33 is avoided, and abnormal noise during operation of the window regulator device 20 and wear and damage of the open side cable 33 are prevented in advance.

  Next, the assembly procedure of the window regulator device 20 formed as described above will be described with reference to FIG.

When the carrier plate 40 slides on the 50 and 60, the first and second sliding portions 46 and 47 swing in the first and second guide grooves 51 and 61 as shown by an arrow m2 in FIG. It comes to move. Therefore, smooth and stable operation of the carrier plate 40 is possible while reducing the operating noise of the window regulator device 20. Here, it is desirable to apply sliding grease (not shown) between the first and second sliding portions 46 and 47 and the first and second guide grooves 51 and 61.

  Moreover, as shown in FIG. 11, since the cross-sectional shape along the longitudinal direction of the 1st, 2nd sliding parts 46 and 47 is formed in the substantially circular arc shape, the carrier plate 40 is shown to the arrow m3 of FIG. Thus, it can swing to the open side cable 33 side and the close side cable 34 side. Accordingly, not only the smooth operation of the carrier plate 40 but also the switching operation from the ascending drive to the descending drive of the window glass 12 or the descending drive of the window glass 12 to the ascending drive can be performed smoothly without rattling. Yes.

  As described above in detail, according to the window regulator device 20 of the present embodiment, the carrier plate 40 including the first and second sliding portions 46 and 47 by the first and second guide rails 50 and 60. The drum 35 is disposed between the first and second guide rails 50 and 60 so that the first and second guide rails 50 and 60 face each other in the radial direction of the drum 35. A space can be formed between the first and second guide rails 50 and 60, and the drive motor 30 can be disposed in that portion.

  Therefore, the window regulator device 20 can be reduced in size while suppressing an increase in the thickness dimension. In addition, since the conventional base plate can be replaced with the two rod-shaped guide rails 50 and 60, the weight can be reduced as compared with the conventional one.

  Further, the first guide rail 50 guides the sliding of the first sliding portion 46 and the sliding of the open-side cable 33 and the closed-side cable 34, and the second guide rail 60 is the sliding of the second sliding portion 47. Since the movement is guided, the open side cable 33 and the close side cable 34 for raising and lowering the carrier plate 40 can be straightened along the first guide rail 50.

  Accordingly, the carrier plate 40 can be stably raised and lowered along the first and second guide rails 50 and 60 while preventing the open side cable 33 and the closed side cable 34 from falling off the first guide rail 50. Can do.
