[0011] (1) Window regulator A window regulator 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view of the window regulator according to an embodiment of the present invention. FIG. 2 is a side view of the window regulator. In the following description, the front view of the window regulator 1 will be described as a plan view of the window regulator 1. FIG. 1 depicts an X-axis, a Y-axis, and a Z-axis. The depth direction of the paper in FIG. 1 is referred to as the thickness direction or X-direction, the front side is referred to as one side of the thickness direction or "+X-direction," and the back side is referred to as the other side of the thickness direction or "-X-direction." In addition, in FIG. 1, the left-right direction is referred to as the width direction or Y-direction, the left side is referred to as one side of the width direction or "+Y-direction," and the right side is referred to as the other side of the width direction or "-Y-direction." In addition, in FIG. 1, the up-down direction is referred to as the length direction or Z-direction, the up direction is referred to as the "+Z-direction," and the down direction is referred to as the "-Z-direction." The direction in which the window glass rises and falls is called the up and down direction (Z direction), and the direction in which the window glass rises is sometimes called the "+Z direction" and the direction in which the window glass falls is sometimes called the "-Z direction."
[0012] The window regulator 1 is supported on a door panel (not shown) of a vehicle and is a mechanism for moving a window glass (not shown), which is an object to be moved, up and down.
[0013] As shown in FIGS. 1 and 2, the window regulator 1 mainly includes a guide rail 31, a carrier plate 32, an ascending cable 33, a descending cable , and a drive unit .
[0014] The guide rail 31 is provided along the direction in which the window glass rises and falls (Z direction), and is a member that guides the carrier plate 32 in the direction in which the window glass rises and falls. The guide rail 31 extends generally in the vertical direction of the vehicle (Z direction), and more specifically, is inclined slightly obliquely with respect to the window glass to be installed.
[0015] 3 is a perspective view of the carrier plate 32 attached to the guide rail 31. The carrier plate 32 is a member that holds the lower end of the window glass and is engaged with the guide rail 31 to be slidably guided in the direction in which the window glass is raised and lowered. The carrier plate 32 rises and falls along the edge of the guide rail 31. The structure of the carrier plate 32 will be described in detail later.
[0016] At the upper end of the guide rail 31, an upper cable guide 45 (see FIG. 1) is provided as a direction changing member for changing the moving direction of the ascending cable 33.
[0017] 1 and 2, a drive unit 35 for winding and unwinding the ascending cable 33 and the descending cable 34 is provided at the lower end of the guide rail 31. The drive unit 35 has a drum housing 51, a drum (not shown), and a drive motor 56. The drum housing 51 is attached to the lower end of the guide rail 31, and fixes the guide rail 31 to a door panel (not shown) of the vehicle.
[0018] The drum is rotatably supported by a drum housing 51. A drive motor 56 is attached integrally to the drum housing 51 and drives the drum to rotate in both forward and reverse directions.
[0019] The ascending cable 33 and the descending cable 34 pull the carrier plate 32 in the vertical direction (Z direction), and may be a known cable made of a plurality of metal wires or resin fiber wires twisted together. One end of the ascending cable 33 is connected to the carrier plate 32, is looped around the upper cable guide 45, and the other end is connected to the drum. One end of the descending cable 34 is connected to the carrier plate 32, and the other end is connected to the drum.
[0020] The drive motor 56 rotates the drum to wind and unwind the ascending cable 33 and the descending cable 34 .
[0021] 4 is an arrow view of the carrier plate as seen from the other side in the thickness direction. End 33a (corresponding to the "cable end" of the present invention) and end 34a (corresponding to the "cable end" of the present invention) are provided at one end of ascending cable 33 or descending cable 34. End 33a and end 34a are formed, for example, by die-casting a metal material, and have a base end to which one end of ascending cable 33 or descending cable 34 is attached, and a flange portion with an outer diameter larger than that of the base end. The base end is formed in a cylindrical or truncated cone shape, and one end of ascending cable 33 or descending cable 34 is fixed by adhesive, welding, bolting, or other methods.
[0022] Coil springs 85 and 87 are attached to the ends 33a and 34a, respectively. The coil springs 85 and 87 are biasing members that bias the ends 33a and 34a in the direction of removing slack in the ascending cable 33 and the descending cable 34.
[0023] (2) Guide rail The guide rail 31 is gently curved to match the curvature of the window glass of the automobile, and is made of, for example, stainless steel, aluminum alloy, or other hard material.
[0024] The front view of the guide rail 31 depicted in FIG. 1 is superimposed with a U-shaped cross section C of the guide rail 31 as viewed from above. The guide rail 31 has a base 37, side wall portions 38a, 38b, and flange portions 39a, 39b. The base 37 has a predetermined length in the width direction (Y direction) and extends in the up-down direction (Z direction). The side wall portion 38a is located at one end of the base 37 in the width direction (+Y direction) and stands upright from the long side of the base 37 along the length direction (Z direction) of the base 37. The side wall portion 38b is located at the other end of the base 37 in the width direction (-Y direction) and stands upright from the long side of the base 37 along the length direction (Z direction) of the base 37. The side wall portions 38a and 38b correspond to the "standing portions" of the present invention.
[0025] The flange portion 39a is bent at a right angle from the side wall portion 38a and extends parallel to the base portion 37 toward one end in the width direction (+Y direction).
[0026] The flange portion 39b is bent at a right angle from the side wall portion 38b and extends parallel to the base portion 37 toward the other end in the width direction (-Y direction).
[0027] (3) Drum housing The drum housing 51 has a main body 51a having a fitting portion for the guide rail 31 and a cylindrical drum accommodating portion. A cylindrical recess for accommodating the drum is formed in the main body 51a. An ascending-side cable guide groove 57 and a descending-side cable guide groove 59 are formed in the main body 51a to pass the ascending-side cable 33 and the descending-side cable 34 through the recesses and lead them out to the outside.
[0028] (4) Carrier plate structure Next, the structure of carrier plate 32 in this embodiment will be described with reference to Figures 4, 5, and 6A. Figure 5 is a view of carrier plate 32 as seen from above. Figure 6A is a partial cross-sectional view showing the structure of carrier plate 32 in this embodiment.
[0029] The carrier plate 32 has a main body 32a, which is a base and on which other structures are formed.
[0030] Mounting portions 71 and 73 are provided on surface 32b (corresponding to the "second surface" of the present invention) located on one side in the thickness direction (+X direction) of main body 32a. A holder (not shown) for holding a window glass (not shown) is attached to mounting portions 71 and 73. Furthermore, surface 32c located on the other side in the thickness direction (-X direction) of main body 32a is provided with guide groove 75 (corresponding to the "fitting portion" of the present invention), anti-rotation claw 77, elastic claw 78, ascending-side end holder 79 (corresponding to the "accommodating portion" of the present invention), and descending-side end holder 81 (corresponding to the "accommodating portion" of the present invention).
[0031] The guide groove 75 is disposed in the center in the width direction (Y direction). The guide groove 75 has an opening 75a that opens to the other side in the thickness direction of the main body 32a (-X direction), a groove 75b that extends from the opening 75a to one side in the thickness direction (+X direction), and a groove 75c that extends from the bottom of the groove 75b to one side in the width direction (+Y direction). The groove 75b is a groove that slides over the side wall portion 38a of the guide rail 31 (see FIG. 6A). The groove 75c is a groove that slides over the flange portion 39a of the guide rail 31 (see FIG. 6A).
[0032] 6A, when the carrier plate 32 is assembled to the guide rail 31, in other words, when the guide groove 75 is slidable on the side wall portion 38a and the flange portion 39a, the gap between the groove 75b and the side wall portion 38a is small. The gap between the groove 75c and the flange portion 39a is also small. The side wall portion 38a and the flange portion 39a have an L-shaped cross section in the XY plane. This prevents the central portion of the carrier plate 32, which is located in the center of the width direction, from wobbling in the thickness direction (X direction) and width direction (Y direction) relative to the side wall portion 38a and the flange portion 39a.
[0033] The anti-rotation claw 77 is disposed on the other widthwise side (-Y direction) of the guide groove 75. The anti-rotation claw 77 prevents rotation of the carrier plate 32 around the guide groove 75. The anti-rotation claw 77 has a wall 77a extending in the -X direction from a surface 32c located on the other thicknesswise side (-X direction) of the main body 32a, and a protrusion 77b protruding from the tip of the wall 77a to one widthwise side (+Y direction). The protrusion 77b has a first protrusion 77b1 and a second protrusion 77b2. The first protrusion 77b1 and the second protrusion 77b2 are disposed spaced apart in the up-down direction (Z direction).
[0034] The elastic claw 78 is disposed between the guide groove 75 and the anti-rotation claw 77 in the width direction (Y direction). The elastic claw 78 has a base end 78a disposed on a surface 32c on the other side in the thickness direction (-X direction) of the main body 32a, an extension portion 78b extending obliquely from the base end 78a toward the other side in the width direction (-Y direction) relative to the other side in the thickness direction (-X direction), and a tip end 78c protruding from the extension portion 78b toward the other side in the width direction (-Y direction) so as to be adjacent to the protrusion 77b. The tip end 78c is disposed between the first claw portion 77b1 and the second claw portion 77b2 in a plan view from the thickness direction. The tip end 78c is located closer to one side in the thickness direction (+X direction) than the first claw portion 77b1 and the second claw portion 77b2.
[0035] The elastic claws 78 have elasticity. As a result, when the elastic claws 78 are bent to one side in the thickness direction (+X direction) due to, for example, an external force, they have a restoring force that causes them to return to the other side in the thickness direction (-X direction).
[0036] Next, the relative positions of anti-rotation claw 77 and resilient claw 78 will be described with reference to FIGS. 4, 5, 6A, and 6B. FIG. 6B is a partial cross-sectional view showing the carrier plate during assembly in this embodiment. Anti-rotation claw 77 has a first claw portion 77b1 and a second claw portion 77b2. Resilient claw 78 has a tip portion 78c that is positioned between first claw portion 77b1 and second claw portion 77b2 in a plan view from the thickness direction (see FIGS. 4 and 6B).
[0037] In the following description of the assembly work of the carrier plate 32 in this embodiment and the assembly work of the carrier plate 320 in the comparative example, the positional relationship with the obstacle will be explained by applying it to the ascending cable 33, but this is not limited to this and it may also be applied to the descending cable 34.
[0038] In the assembly process of the window regulator 1, the end 33a of the ascending-side cable 33 is attached to the carrier plate 32 before the carrier plate 32 is attached to the guide rail 31. Furthermore, the ascending-side cable 33 is routed between the guide rail 31 and the carrier plate 32. As a result, in the conventional carrier plate 320, there was a risk that the ascending-side cable 33 would get caught between the elastic claw 78 and the anti-rotation claw 77 during the assembly work shown in FIG. 6B in which the carrier plate 32 is attached to the guide rail 31. However, in the carrier plate 32 of the present embodiment, the tip portion 78c is located between the first claw portion 77b1 and the second claw portion 77b2 in a plan view from the thickness direction, making it possible to prevent the ascending-side cable 33 from getting caught between the first claw portion 77b1 and the second claw portion 77b2.
[0039] In the state shown in FIG. 6A in which the carrier plate 32 is assembled to the guide rail 31, in other words, in a state in which the groove (gap) provided between the tip end 78c and the protrusion 77b allows the flange portion 39b to slide, the tip end 78c, together with the protrusion 77b, sandwiches the flange portion 39b in the thickness direction (X direction). In this case, the tip end 78c presses the flange portion 39b toward the protrusion 77b (-X direction). That is, the tip end 78c contacts a surface 39b1 (corresponding to the "first surface" of the present invention) located on one side of the thickness direction (+X direction) of the flange portion 39b. Furthermore, the protrusion 77b contacts a surface 39b2 (corresponding to the "second surface" of the present invention) located on the other side of the thickness direction (-X direction) of the flange portion 39b. As a result, the end portion of the carrier plate 32 on the other side in the width direction (-Y direction) is less likely to wobble in the thickness direction (X direction) relative to the flange portion 39b.
[0040] 6A in which the carrier plate 32 is assembled to the guide rail 31, the guide groove 75 slides on the flange portion 39a provided on the guide rail 31. The groove (gap) provided between the protrusion 77b and the tip end 78c slides on the flange portion 39b provided on the guide rail 31. The flange portion 39b is locked in the thickness direction (X direction) by the protrusion 77b, so that the carrier plate 32 is prevented from rotating around the flange portion 39a.
[0041] 6A, in which the carrier plate 32 is mounted on the guide rail 31, the carrier plate 32 and the guide rail 31 form a closed space CS. The ascending cable 33 is located at the center of the closed space CS in the width direction (Y direction) and passes through the closed space CS in the vertical direction (Z direction). There are no obstacles in the closed space CS that would prevent the ascending cable 33 from moving in the width direction (Y direction). This allows the ascending cable 33 to move from one position closer to the side wall 38a or the other position closer to the side wall 38b within the closed space CS. Because there are no obstacles within the closed space CS that would prevent the ascending-side cable 33 from moving in the width direction (Y direction), even if the ascending-side cable 33 is positioned closer to the side wall 38b during the assembling operation of the carrier plate 32, it is possible to move the ascending-side cable 33 from the position closer to the side wall 38b to a position in the center of the width direction (Y direction) within the closed space CS by the time the assembling operation of the carrier plate 32 is completed. In the following description, the position of the ascending-side cable 33 upon completion of the assembling operation of the carrier plate 32 is referred to as the "correct position." In Figure 6A, the ascending-side cable 33 in the correct position is shown by a solid line. Furthermore, a position of the ascending-side cable 33 other than the correct position is referred to as the "incorrect position." In Figure 6A, the ascending-side cable 33 in the incorrect position is shown by a dashed line.
[0042] (Comparative Example) Next, the structure of carrier plate 320 in a comparative example will be described with reference to Fig. 7A. Fig. 7A is a partial cross-sectional view showing the structure of carrier plate 320 in the comparative example. Fig. 7B is a partial cross-sectional view showing carrier plate 320 during assembly work in the comparative example. Fig. 7C is an arrow view of the elastic claws in the comparative example as seen from the other side in the width direction. Note that in the description of the comparative example, configurations that differ from the structure of carrier plate 32 in the present embodiment will be described, and the same configurations will be assigned the same symbols and their description will be omitted.
[0043] The carrier plate 320 has a main body 32 a , mounting portions 71 and 73 , a guide groove 75 , a rotation prevention claw 77 , a resilient claw 780 , an ascending-side end holder 79 , and a descending-side end holder 81 .
[0044] The elastic claw 780 in the comparative example is disposed between the guide groove 75 and the anti-rotation claw 77 in the width direction (Y direction). The elastic claw 780 has a base end 780a, which is disposed on a surface 32c located on the other side in the thickness direction (-X direction) of the main body 32a. The elastic claw 780 also has an extension 780b (see FIG. 7C ), which extends obliquely from the base end 780a downward (-Z direction) toward the other side in the thickness direction (-X direction). The tip of the extension 780b is bent in an arc shape toward one side in the thickness direction (+X direction). The extension 780b in the comparative example differs from the extension 780b in the present embodiment, which extends obliquely from the base end 780a toward the other side in the width direction (-Y direction) with respect to the other side in the thickness direction (-X direction). 7A in which the carrier plate 320 is assembled to the guide rail 31, the extension 780b is in contact with a surface located on one side in the thickness direction (+X direction) of the base 37. In other words, the elastic claw 780 is arranged to connect the surface 32c located on the other side in the thickness direction of the main body 32a and the surface located on one side in the thickness direction of the base 37 (+X direction).
[0045] 7A, in which the carrier plate 320 is assembled to the guide rail 31, a closed space CS is formed by the carrier plate 32 and the guide rail 31. The closed space CS is divided by the elastic claw 780 into a space CS1 located on the side wall portion 38a side and a space CS2 located on the side wall portion 38b side.
[0046] While the closed space CS is divided into spaces CS1 and CS2 by the elastic claw 780, the ascending side cable 33 is located in space CS1 located on the side wall portion 38a side and is passed through space CS1 in the vertical direction (Z direction).
[0047] Within the closed space CS, there is an extension portion 780b, which is an obstacle that prevents the ascending-side cable 33 from moving in the width direction (Y direction), so the ascending-side cable 33 is prevented from moving from either a position closer to the side wall portion 38a (space CS1) or a position closer to the side wall portion 38b (space CS2) to the other position. In the following explanation, it is assumed that the position where the carrier plate 320 should be upon completion of the assembly work (the correct position) is the position closer to the side wall portion 38a (space CS1). In Figure 7A, the ascending-side cable 33 in the correct position is shown by a solid line, and the ascending-side cable 33 in the position closer to the side wall portion 38b (the incorrect position) is shown by a dashed line.
[0048] (Assembling work of carrier plate in comparative example) Next, the assembly work of the carrier plate 320 in the comparative example will be described with reference to FIGS. 7A and 7B.
[0049] In assembling the carrier plate 320, as shown in Fig. 7B, the guide groove 75 is fitted into the side wall portion 38a and flange portion 39a, which are the ends located on one widthwise side (+Y direction) of the guide rail 31, and the carrier plate 320 is rotated counterclockwise around the end on one widthwise side in Fig. 7B. At this time, the ascending-side cable 33 may be in an incorrect position, closer to the side wall portion 38b, due to slack or the like. The ascending-side cable in the incorrect position is shown by a dashed line in Fig. 7B.
[0050] Next, the carrier plate 320 is rotated counterclockwise around one end in the width direction, and the flange portion 39b is engaged with the anti-rotation pawl 77, as shown in FIG. 7A. In this manner, the carrier plate 320 is assembled to the guide rail 31. At this time, the ascending-side cable 33 may still be in an incorrect position, toward the side wall portion 38b. In other words, the ascending-side cable 33 may be in the space CS2.
[0051] After the carrier plate 320 is assembled to the guide rail 31, tension is applied to the ascending-side cable 33. As a result, the ascending-side cable 33 tries to remove slack and move from an incorrect position closer to the side wall 38b to a correct position closer to the side wall 38a (space CS1), in other words, along a straight line connecting the ascending-side cable outlet groove 57 of the drum housing 51a and the ascending-side cable 33 outlet portion of the upper pulley 45. In this case, because the closed space CS is divided into spaces CS1 and CS2 by the elastic claw 780, the elastic claw 780 prevents the movement of the ascending-side cable 33. As a result, the ascending-side cable 33 is not routed in the correct position, which requires the assembling work of the carrier plate 320 to be redone, which may reduce the ease of assembling the carrier plate 320.
[0052] (Assembling Work of Carrier Plate in the Present Embodiment) Next, the assembly work of the carrier plate 32 in this embodiment will be described with reference to Figures 6A and 6B. Figure 6B is a partial cross-sectional view showing the carrier plate during the installation work in this embodiment. In the following description, it is assumed that the position (correct position) of the carrier plate 32 upon completion of the installation work is the center position in the width direction (Y direction) of the closed space CS. In Figure 6B, the ascending side cable 33 in the correct position is shown by a solid line. Furthermore, the ascending side cable 33 in an incorrect position, which is closer to the side wall portion 38b, is shown by a dashed line.
[0053] In assembling the carrier plate 32, as shown in Fig. 6B, the guide groove 75 is fitted into the side wall portion 38a and flange portion 39a, which are the ends located on one widthwise side (+Y direction) of the guide rail 31, and the carrier plate 32 is rotated counterclockwise around the end on one widthwise side in Fig. 6B. At this time, the ascending-side cable 33 may be in an incorrect position, closer to the side wall portion 38b, due to slack or the like.
[0054] Next, the carrier plate 32 is rotated counterclockwise around one end in the width direction, and the flange portion 39b is engaged with the anti-rotation pawl 77, as shown in Fig. 6A. In this manner, the carrier plate 32 is assembled to the guide rail 31. At this time, the ascending cable 33 may still be in an incorrect position, toward the side wall portion 38b.
[0055] After the carrier plate 32 is assembled to the guide rail 31, tension is applied to the ascending-side cable 33. This causes the ascending-side cable 33 to try to remove slack and move from the incorrect position to the correct position, which is closer to the side wall 38a. In this case, since there is no obstacle in the closed space CS that would hinder the movement of the ascending-side cable 33, the ascending-side cable 33 is routed from the incorrect position to the correct position. This eliminates the need to redo the assembly work of the carrier plate 32, thereby improving the efficiency of the assembly work of the carrier plate 32.
[0056] The carrier plate 32 in the above embodiment is a carrier plate that is slidably guided on the guide rail 31 by the driving force of the drive unit 35 being transmitted by the ascending side cable 33 and the descending side cable 34, and has a base 37, a guide groove 75 that fits into the guide rail 31, a rotation prevention claw 77 that is provided on one widthwise side of the base 37 and spaced apart from the guide groove 75, and that prevents the carrier plate 32 from rotating around the guide groove 75 relative to the guide rail 31, an ascending side end holder 79 and a descending side end holder 81 that are provided on the other widthwise side of the base 37 relative to the guide groove 75, and that accommodate the respective ends of the ascending side cable 33 and the descending side cable 34, and an elastic claw 78 that comes into contact with a surface located on one thickness direction side (+X direction) of the flange portion 39b.
[0057] With the above configuration, during the installation work of assembling the carrier plate 32 to the guide rail 31, the elastic claw 78 comes into contact with the surface 39b1 of the flange portion 39b, so the movement of the ascending-side cable 33 is not hindered by the elastic claw 78, compared to a structure in which the elastic claw 78 comes into contact with one side surface in the thickness direction of the base portion 33 of the guide rail 31 along the movement path of the ascending-side cable 33 within the closed space CS. In other words, the ascending-side cable 33 is prevented from getting caught between the anti-rotation claw 77 and the elastic claw 78. This eliminates the need to redo the assembling work of the carrier plate 32, so it is possible to improve the efficiency of assembling the window regulator 1 even with a structure in which the elastic claw 78 comes into contact with the guide rail 31.
[0058] Furthermore, in the carrier plate 32 according to the above embodiment, the anti-rotation claw 77 has a first claw portion 77b1 and a second claw portion 77b2, which are spaced apart in the up-down direction (Z direction) of the base 37. The tip portion 78c of the elastic claw 78 is located in the region between the first claw portion 77b1 and the second claw portion 77b2, that is, between the first claw portion 77b1 and the second claw portion 77b2 in a plan view. Even if the ascending-side cable 33 attempts to enter between the anti-rotation claw 77 and the elastic claw 78, the tip portion 78c is located between the first claw portion 77b1 and the second claw portion 77b2, preventing the ascending-side cable 33 from entering. Furthermore, since the elastic claw 78 is sandwiched between the first claw portion b1 and the second claw portion b2 in plan view, rattle caused by the elastic claw 78 pressing against the surface 39b1 of the flange portion 39b is prevented even more effectively.
[0059] Furthermore, in the carrier plate 32 in the above embodiment, the elastic claws 78 extend in the width direction (Y direction) of the base 37. When the ascending-side cable 33 attempts to move in the width direction during the assembling work of the carrier plate 32, the ascending-side cable 33 is more likely to move along the elastic claws 78. Furthermore, the carrier plate can be made smaller than when the elastic claws 78 and the anti-rotation claws 77 are arranged along the up-down direction (Z direction) of the base 37 on the flange portion 39b. Furthermore, since the elastic claw 78 has an extension portion 78b that extends diagonally from the base end portion 78a located on the surface 32c on the other side in the thickness direction (-X direction) of the main body 32a to the other side in the width direction (-Y direction) relative to the other side in the thickness direction (-X direction) thereof, even if the lifting cable 33 comes into contact with the surface of the elastic claw 78 on the base 33 side during the carrier plate installation work, the lifting cable 33 can be guided toward the base 33, thereby further preventing the lifting cable 33 from entering the inside of the elastic claw 78 (the space on the main body 32a side of the elastic claw 78).
[0060] (Variation 1) Next, a modified structure for preventing the ascending cable 33 from entering between the rotation prevention claw 77 and the elastic claw 78 will be described. In the above embodiment, the anti-rotation claw 77 and the resilient claw 78 may have an overlapping region when viewed in a direction perpendicular to the thickness direction (X direction) and width direction (Y direction) of the carrier plate 32, i.e., in the up-down direction (Z direction). Even if the ascending-side cable 33 attempts to enter between the anti-rotation claw 77 and the resilient claw 78, the anti-rotation claw 77 and the resilient claw 78 overlap in the up-down direction (X direction), so the ascending-side cable 33 can be prevented from entering.
[0061] (Variation 2) In the above embodiment, the gap between the resilient claw 78 and the anti-rotation claw 77 may be smaller than the outer diameter of the ascending-side cable 33. In other words, the gap formed by 78c of the resilient claw 78 and the protrusion 77b of the anti-rotation claw 77 is smaller than the outer diameter of the ascending-side cable 33. As a result, even if the ascending-side cable 33 is separated from one surface in the thickness direction of the main body 33 of the guide rail 31 and positioned on the surface 32c side of the carrier plate 32, that is, in a position close to the resilient claw 78, even if the ascending-side cable 33 tries to enter between the anti-rotation claw 77 and the resilient claw 78, it cannot pass through the gap, and therefore the ascending-side cable 33 can be prevented from entering.
[0062] (Variation 3) In the above embodiment, the elastic claws 78 extend in the width direction (Y direction) of the base 37. However, the present invention is not limited to this. The elastic claws 78 may extend in a direction perpendicular to both the width direction (Y direction) of the base 37 and the thickness direction (X direction) of the carrier plate 32, i.e., in the up-down direction (Z direction). Even in this case, the anti-rotation claws 77 and the elastic claws 78 form a structure that prevents the ascending cable 33 from entering between the anti-rotation claws 77 and the elastic claws 78. Furthermore, in this case, the elastic claws 77 and the anti-rotation claws 77 are arranged along the flange portion 39b, making it difficult for the ascending cable 33 to enter the gap between the elastic claws 78 and the anti-rotation claws 77. Furthermore, because the elastic claws 78 are arranged along the flange portion 39b, sliding resistance is less likely to occur when the carrier plate 32 slides on the guide rail 31.
[0063] (Variation 4) In the above embodiment, a gap may be provided between the anti-rotation claw 77 and the elastic claw 78 to prevent the ascending-side cable 33 from entering from the thickness direction (X direction) of the carrier plate 32. This makes it possible to prevent the ascending-side cable 33 from entering between the anti-rotation claw 77 and the elastic claw 78 even if the ascending-side cable 33 attempts to enter between the anti-rotation claw 77 and the elastic claw 78 from the thickness direction (X direction). Specifically, the gap provided between the anti-rotation claw 77 and the elastic claw 78 may be a curved gap when viewed in the thickness direction (X direction) of the carrier plate 32. This makes it possible to prevent the ascending-side cable 33, which is routed linearly, from entering the gap from the thickness direction (X direction) because the gap is curved.
[0064] (Variation 5) In the above embodiment, the protrusion 77b of the anti-rotation pawl 77 has a tip edge extending in the vertical direction (Z direction), and the tip edge may have a central portion located in the vertical center of the tip edge having a recess that recesses toward the other widthwise side (-Y direction) in a plan view from the thickness direction (X direction). Furthermore, the tip portion 78c of the elastic pawl 78 may be disposed so as to fit into the recess in a plan view from the thickness direction. By fitting the tip portion 78c into the recess, the gap between the anti-rotation pawl 77 and the elastic pawl 78 is not linear, making it possible to prevent the ascending-side cable 33, which is routed linearly, from entering the gap.
[0065] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible within the scope of the gist of the invention. In particular, the multiple embodiments and modifications described in this specification can be arbitrarily combined as necessary. [Industrial Applicability]
