Description

Technical Field

[0001] The present invention relates to an object moving device and a window regulator.

Background Art

[0002] A window regulator is used as a device for raising and lowering a vehicle window glass (see, for example, Patent Document 1). The window regulator shown in Patent Document 1 includes a carrier plate that holds the window glass, a guide rail that guides the carrier plate, a cable having one end connected to the carrier plate, a direction-changing member such as a cable guide that is disposed at the upper and lower ends of the guide rail and changes the direction of the cable, a drum to which the other end of the cable is connected, a drive motor that rotationally drives the drum, and a drum housing that houses the drum. When the drive motor rotationally drives the drum, the cable is wound or unwound, and thereby, the carrier plate is raised or lowered to raise and lower the window glass.

[0003] When assembling such a window regulator, mounting members such as the direction-changing member and the drum housing are inserted into the guide rail and are fixed to the guide rail by being pressed and constrained in the direction of insertion into the guide rail by the tension of the cable in a state of being inserted into the guide rail. However, in a state where the mounting member is inserted into the guide rail, the mounting member may fall off from the guide rail before the tension by the cable is generated.

[0004] Therefore, in order to prevent the mounting member attached to the guide rail from falling off from the guide rail during assembly, a configuration has been proposed in which a claw member for preventing detachment is provided on the mounting member and a fitting hole for fitting with the claw member is provided on the guide rail.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, when a claw member is provided on the attachment member to prevent detachment during assembly, when vibration is transmitted to the attachment member after the assembly of the window regulator, there is a problem that the claw member contacts the inner wall of the fitting hole and abnormal noise is generated.

[0007] An object of the present invention is to provide an object moving device and a window regulator capable of reducing the generation of abnormal noise.

Means for Solving the Problems

[0008] The object moving device of the present invention includes a moving member, a guide rail, a drum, and an attachment member. The moving member has a moving object attached thereto. The guide rail extends in the moving direction of the moving object and is slidably engaged with the moving member. A cable is connected to the moving member. The drum winds or pays out the cable so as to move the moving member along the guide rail. The attachment member is attached to an end portion in the extending direction of the guide rail, and the tension of the cable acts thereon. The attachment member has a fitting portion for preventing detachment from the guide rail. The guide rail has a fitting hole into which the fitting portion fits in a loose-fitting state. In a state where the tension of the cable acts on the attachment member, the fitting portion is disposed at a distance from the guide rail.

[0009] The window regulator of the present invention includes a drive unit, a carrier plate, a guide rail, a cable, a cable guide, a drum, and a drum housing. The carrier plate holds the window glass. The guide rail extends in the moving direction of the carrier plate and slidably engages with the carrier plate. One end of the cable is connected to the carrier plate, and the carrier plate is pulled in the moving direction of the carrier plate by being driven by the drive unit. The cable guide changes the direction of the cable. The other end of the cable is connected to the drum, and the drum winds or unwinds the cable wound around the cable guide by being driven by the drive unit. The drum housing rotatably houses the drum. The fitting portion is provided on at least one of the cable guide and the drum housing to prevent detachment from the guide rail. A fitting hole into which the fitting portion is loosely fitted is formed in the guide rail. In a state where the cable guide and the drum housing are attached to the guide rail and the tension of the cable acts on the cable guide and the drum housing, the fitting portion is disposed spaced apart from the guide rail.

Advantages of the Invention

[0010] According to the present invention, it is possible to provide an object moving device and a window regulator capable of reducing the generation of abnormal noise.

FIG. 3(b) is a cross-sectional view taken along the line EE of FIG. 3(a). In FIGS. 3(a) and 3(b), the vehicle width direction perpendicular to the vertical direction A and the front-rear direction B is indicated by C. Among the vehicle width direction C, the inner direction in the state where the window regulator 1 is attached to the vehicle is indicated by an arrow C1, and the outer direction is indicated by an arrow C2.

[0024] As shown in FIGS. 1 and 2, although the guide rail 2 generally extends in the vertical direction A, in the state where it is attached to the vehicle, the extending direction of the guide rail 2 is inclined with respect to the vertical direction A. The guide rail 2 is attached to the vehicle such that the upper end portion 2a shown in FIG. 3(a) is located on the rearward B2 side with respect to the lower end portion 2b. The extending direction of the guide rail 2 is indicated by D, and among the extending direction D, the extending upward direction is indicated by an arrow D1, and the extending downward direction is indicated by an arrow D2.

[0025] As shown in FIGS. 3(a) and 3(b), the guide rail 2 has a rail main body portion 20, a first vertical wall portion 21, a second vertical wall portion 22, an extension portion 23, a fitting hole 24, and a fitting hole 25.

[0026] The rail main body portion 20 is a plate-shaped portion arranged in parallel with the front-rear direction B. The rail main body portion 20 extends in the vertical direction A. The rail main body portion 20 is curved so as to bulge toward the outer direction C2. The rail main body portion 20 has an end 20a on the frontward B1 side and an end 20b on the rearward B2 side in the front-rear direction B. The surface on the outer direction C2 side of the rail main body portion 20 is indicated by 20c, and the surface on the inner direction C1 side is indicated by 20d.

[0027] The first vertical wall portion 21 is arranged at the end 20a in the front-rear direction B (an example of the width direction) of the rail main body portion 20. The first vertical wall portion 21 extends from the end 20a of the rail main body portion 20 toward the outer direction C2 side. The first vertical wall portion 21 is arranged perpendicular to the rail main body portion 20.

[0028] The second vertical wall portion 22 is disposed at the end 20b. The second vertical wall portion 22 extends outward in the C2 direction from the end 20b. The second vertical wall portion 22 is disposed perpendicular to the rail main body portion 20. The second vertical wall portion 22 is disposed opposite to the first vertical wall portion 21 in the front-rear direction B.

[0029] The extending portion 23 extends in the forward direction B1, which is the direction opposite to the rail main body portion 20 in the front-rear direction B, from the end on the outer C2 side of the second vertical wall portion 22. The extending portion 23 is formed parallel to the rail main body portion 20.

[0030] The fitting hole 24 is formed in the rail main body portion 20 near the end portion 2a. The fitting hole 24 penetrates from the surface 20c to the surface 20d of the rail main body portion 20. The fitting hole 25 is formed in the rail main body portion 20 near the end portion 2b. The fitting hole 25 penetrates from the surface 20c to the surface 20d of the rail main body portion 20.

FIG. 6(b) is a cross-sectional view showing a state where the guide rail 2 is removed from the cable guide 4 in FIG. 6(a). FIG. 7 is a cross-sectional view between GG in FIG. 4(a). FIGS. 8(a) to 8(c) are views showing the attachment operation of the cable guide 4 to the guide rail 2.

[0032] As shown in FIG. 6(b), the cable guide 4 includes a cable guide main body 41 (an example of an attachment member main body), a rail insertion portion 42 (an example of an insertion portion), a through hole 43, and a fitting portion 44.

[0033] As shown in Fig. 5(a), the cable guide body 41 is substantially semi-circular. The cable guide body 41 has a curved portion 411 and a lower surface portion 412. The curved portion 411 constitutes the curved semi-circle in the outer shape of the cable guide body 41 when viewed from the front. The curved portion 411 is arranged on the upward A1 side of the cable guide body 41. The cable 6 is wound along the curved portion 411. The cable 6 changes its direction from the upward A1 to the downward A2 due to the curved portion 411. The lower surface portion 412 is the end face portion on the downward A2 side of the cable guide body 41. As shown in Fig. 6(a), the lower surface portion 412 constitutes the diameter portion of the semi-circle in the outer shape of the cable guide body 41. A rail insertion portion 42 is formed from the lower surface portion 412.

[0034] The rail insertion portion 42 is an insertion hole into which the guide rail 2 is inserted. The rail insertion portion 42 is formed in the cable guide body 41. As shown in Figs. 6(a) and 6(b), the rail insertion portion 42 is formed to extend upward in the D1 direction from the lower surface portion 412. When attaching the cable guide 4 to the guide rail 2, the end portion 2a of the guide rail 2 is inserted into the rail insertion portion 42 from the lower surface portion 412 of the cable guide 4 and is moved relative to the cable guide 4 in the upward D1 direction of extension.

[0035] As shown in Fig. 7, the rail insertion portion 42 has a first insertion portion 421, a second insertion portion 422, a third insertion portion 423, and a fourth insertion portion 424. The first insertion portion 421 is formed along the front-rear direction B. The rail main body portion 20 of the guide rail 2 is inserted into the first insertion portion 421.

[0036] The second insertion part 422 is formed from the rearward B2-side end of the first insertion part 421 toward the outer direction C2. The first vertical wall part 21 of the guide rail 2 is inserted into the second insertion part 422. The third insertion part 423 is formed from the forward B1-side end of the first insertion part 421 toward the outer direction C2. The second vertical wall part 22 of the guide rail 2 is inserted into the third insertion part 423. The fourth insertion part 424 is formed from the outer direction C2-side end of the third insertion part 423 toward the forward B1. The extension part 23 of the guide rail 2 is inserted into the fourth insertion part 424.

[0037] As shown in FIG. 6(b), the through hole 43 penetrates the cable guide body 41. The cable guide body 41 has a first surface 41a facing the inner direction C1 and a second surface 41b facing the outer direction C2. The through hole 43 is formed from the first surface 41a to the second surface 41b. The through hole 43 penetrates the rail insertion part 42. The through hole 43 is formed perpendicular to the rail main body part 20 of the guide rail 2 in a state where the guide rail 2 is attached. As shown in FIGS. 4(a) and 4(b), in a state where the guide rail 2 is attached to the cable guide 4, the fitting hole 24 of the guide rail 2 is located inside the through hole 43.

[0038] The fitting part 44 prevents the cable guide 4 from detaching from the guide rail 2 when assembling the window regulator 1. The fitting part 44 prevents the cable guide 4 from detaching from the guide rail 2 by fitting into the fitting hole 24. The fitting part 44 fits into the fitting hole 24 in a loose fitting state. The fitting part 44 is disposed inside the through hole 43.

[0039] As shown in FIG. 6(a), the fitting part 44 is disposed on the outer direction C2 side of the surface 20c of the guide rail 2.

[0040] The fitting portion 44 has a protrusion 441 and an extension portion 442. As shown in FIGS. 6(a) and 8(c), at least a part of the protrusion 441 is disposed in the fitting hole 24 when the cable guide 4 is attached to the guide rail 2. The extension portion 442 extends from the cable guide main body 41 to the protrusion 441 and is disposed spaced apart from the surface of the guide rail 2. The extension portion 442 extends from the edge 43e on the upward extension direction D1 side of the through hole 43 toward the downward extension direction D2. The base end portion 442a connected to the edge 43e of the extension portion 442 is spaced outwardly from the surface 20c of the guide rail 2 on the C2 side as shown in FIG. 6(a). As shown in FIG. 7, if the inner wall surface of the cable guide main body 41 on the C2 side of the first insertion portion 421 is 414, two protrusions 415 are provided on the inner wall surface 414. The protrusions 415 are provided along the extension direction D as shown in FIG. 8(a). The tip surfaces 415a of these protrusions 415 restrict the movement of the rail main body portion 20 outwardly on the C2 side as shown in FIG. 7. The base end portion 442a is spaced more outwardly on the C2 side than the tip surface 415a as shown in FIG. 8(a). In a state where the cable guide 4 is attached to the guide rail 2, as shown in FIG. 6(a), the extension portion 442 is inclined so as to move away from the guide rail 2 as it extends downward from the base end portion 442a in the D2 direction.

[0041] As shown in FIG. 6(b), the protrusion 441 is disposed at the end on the downward extension direction D2 side of the extension portion 442. The protrusion 441 is formed to protrude inwardly from the extension portion 442 in the C1 direction. In a state where the cable guide 4 is attached to the guide rail 2, as shown in FIG. 6(a), the protrusion 441 is formed to protrude from the extension portion 442 toward the fitting hole 24.

[0042] The protrusion 441 has a gradient portion 443. As shown in Fig. 6(a), the gradient portion 443 is arranged on the side not facing the end portion 2a in the state where the cable guide 4 is attached to the guide rail 2. The gradient portion 443 is arranged on the inner direction C1 side of the protrusion 441. The gradient portion 443 is formed so as to extend from the end on the downward extension direction D2 side of the protrusion 441 toward the upward extension direction D1 side. The gradient portion 443 is inclined so as to face the inner direction C1 as it goes toward the upward extension direction D1. The gradient portion 443 is inclined so as to approach the fitting hole 24 as it approaches the end portion 2a. The tip portion 444 is the portion on the innermost C1 side of the gradient portion 443. The tip portion 444 is arranged inside the fitting hole 24 in the state where the cable guide 4 is attached to the guide rail 2.

[0043] (Attachment of the cable guide 4 to the guide rail 2) When attaching the cable guide 4 to the guide rail 2, as shown in Fig. 8(a), the end portion 2a of the guide rail 2 is inserted into the rail insertion portion 42 of the cable guide 4.

[0044] When the end portion 2a of the guide rail 2 is inserted into the rail insertion portion 42, as shown in Fig. 8(b), the end portion 2a abuts against the gradient portion 443. Specifically, as shown in Fig. 8(a), the end portion 2a of the guide rail 2 has an end face 2c. As shown in Fig. 8(b), the end 2c1 on the outer direction C2 side of the end face 2c abuts against the gradient portion 443.

[0045] When the end portion 2a is further moved deeper into the rail insertion portion 42, the gradient portion 443 slides with the end 2c1 while the fitting portion 44 flexes. Then, when it is further moved, the tip portion 444 of the protrusion 441 slides with the surface 20c of the guide rail 2, and as shown in Fig. 8(c), the tip portion 444 fits into the fitting hole 24.

[0046] In this way, since a part of the fitting portion 44 fits into the fitting hole 24, when assembling the window regulator 1, it is possible to prevent the cable guide 4 from detaching from the guide rail 2.

[0047] When the window regulator 1 is attached to the vehicle, the tensions of the cables 6 and 7 act on the guide rail 2 and the cable guide 4. In the state where such tensions act, the fitting portion 44 is separated from the guide rail 2. Specifically, as shown in FIGS. 4(b) and 6(a), the protrusion 441 of the fitting portion 44 does not contact the edge 24e and the surface 20c of the fitting hole 24, and is separated from the edge 24e and the surface 20c. Also, as shown in FIG. 8(c), the extending portion 442 does not contact the surface 20c of the guide rail 2 and is separated from the surface 20c.

[0048] Therefore, even if vibration is transmitted to the cable guide 4, it is difficult for the fitting portion 44 to contact the guide rail 2, and the generation of abnormal noise can be reduced.

[0049] Note that burrs may occur on the end 2c2 on the inner direction C1 side of the end face 2c of the guide rail 2 shown in FIG. 8(a) (an example of one end in the thickness direction) during the manufacturing process. The fitting portion 44 is disposed on the side opposite to the end 2c2 where burrs may occur. Thereby, it is possible to prevent the gradient portion 443 from contacting the burrs of the end 2c2 of the guide rail 2 and being damaged.

[0050] (Drum housing 13) FIG. 9(a) is an enlarged view showing the vicinity of the winding / unwinding mechanism portion 5 in FIG. 1.

[0051] As shown in FIG. 9(b), the drum housing 13 includes a housing main body 51 (an example of a mounting member main body), a rail insertion portion 52 (see FIG. 11), a through hole 53, and a fitting portion 54.

[0052] As shown in FIGS. 10(a) and 10(b), the housing main body 51 has a drum storage portion 511 which is a cylindrical space, a plurality of fastening portions 512, an upper surface portion 513, and a rail guide portion 514. The drum 11 is stored in the drum storage portion 511. A through hole is formed in each of the plurality of fastening portions 512. A fastening portion 141 having a through hole formed at a position of the motor housing 14 corresponding to each fastening portion 512 is provided, and the motor housing 14 and the drum housing 13 are combined by inserting bolts into the fastening portion 512 and the fastening portion 141. As shown in FIG. 11(b), the upper surface portion 513 is disposed above the drum storage portion 511. The rail insertion portion 52 is formed from the upper surface portion 513. The rail guide portion 514 guides the guide rail 2 into the rail insertion portion 52 when the guide rail 2 is inserted into the rail insertion portion 52. The rail guide portion 514 extends in the upward extension direction D1 from the upper surface portion 513. The rail guide portion 514 is disposed at an edge on the inner direction C1 side of the rail insertion portion 52.

[0053] The rail insertion portion 52 is an insertion hole into which the end portion 2b of the guide rail 2 is inserted. As shown in FIGS. 11(a) and 11(b), the rail insertion portion 52 is formed from the upper surface portion 513 of the housing main body 51 toward the downward extension direction D2. When the drum housing 13 is attached to the guide rail 2, the end portion 2b of the guide rail 2 is inserted into the rail insertion portion 52, and the drum housing 13 is moved in the upward extension direction D1 relative to the drum housing 13.

[0054] As shown in FIGS. 12(a) and 12(b), the rail insertion portion 52 includes a first insertion portion 521, a second insertion portion 522, a third insertion portion 523, and a fourth insertion portion 524. The first insertion portion 521 is formed along the front-rear direction B. The rail main body portion 20 of the guide rail 2 is inserted into the first insertion portion 521.

[0055] The second insertion portion 522 is formed from the rearward B2-side end of the first insertion portion 521 toward the outer direction C2. The first vertical wall portion 21 of the guide rail 2 is inserted into the second insertion portion 522. The third insertion portion 523 is formed from the forward B1-side end of the first insertion portion 521 toward the outer direction C2. The second vertical wall portion 22 of the guide rail 2 is inserted into the third insertion portion 523. The fourth insertion portion 524 is formed from the outer-direction C2-side end of the third insertion portion 523 toward the forward B1. The extension portion 23 of the guide rail 2 is inserted into the fourth insertion portion 524. As shown in FIG. 11(b), on the inner-direction C1 side of the second insertion portion 522, an inner wall 515 of the housing body 51 forming the second insertion portion 522 is disposed. The inner wall 515 is connected to the rail guide portion 514. The rail guide portion 514 is formed such that the inner wall 151 extends in the upward D1 direction. When the surfaces on the first insertion portion 521 side of the inner wall 515 and the rail guide portion 514 are 516, as shown in FIGS. 12(a) and 12(b), two protrusions 517 are provided on the surface 516. The tip surface 517a of the protrusion 517 restricts the movement of the rail main body portion 20 toward the inner direction C1.

[0056] As shown in FIGS. 10 and 11(b), the through hole 53 is formed across the rail guide portion 514 and the inner wall 515. The through hole 53 penetrates the rail guide portion 514 and the inner wall 515 along the vehicle width direction C. The through hole 53 is formed in a long rectangular shape along the extension direction D as shown in FIG. 10.

[0057] The fitting portion 54 prevents the drum housing 13 from detaching from the guide rail 2 when assembling the window regulator 1. The fitting portion 54 prevents the drum housing 13 from detaching from the guide rail 2 by fitting into the fitting hole 25. The fitting portion 54 fits into the fitting hole 25 in a loosely fitting state. The fitting portion 54 is disposed inside the through hole 53.

[0058] As shown in FIG. 11(a), the fitting portion 54 is disposed on the inner-direction C1 side of the surface 20d of the guide rail 2.

[0059] As shown in FIG. 11(b), the fitting portion 54 has a protrusion 541 and an extension portion 542. As shown in FIGS. 11(a) and 13(c), at least a part of the protrusion 541 is disposed in the fitting hole 25 in a state where the drum housing 13 is attached to the guide rail 2. As shown in FIG. 13(c), the extension portion 542 extends from the housing main body 51 to the protrusion 541 and is disposed spaced apart from the surface of the guide rail 2. The extension portion 542 extends from the edge 53e on the upward extension direction D1 side of the through hole 53 toward the downward extension direction D2. The base end portion 542a connected to the edge 53e of the extension portion 542 is spaced inward C1 from the surface 20d of the guide rail 2 as shown in FIG. 13(c). The protrusion 517 is provided along the extension direction D as shown in FIG. 11(b). As shown in FIG. 11(a), the base end portion 542a is located on the inner side C1 with respect to the tip surface 517a. The base end portion 542a is formed lower than the protrusion 517. The tip surface 517a restricts the inward C1 movement of the rail main body portion 20 of the guide rail 2. As shown in FIG. 13(c), in a state where the drum housing 13 is attached to the guide rail 2, the base end portion 542a is spaced from the guide rail 2.

[0060] In a state where the drum housing 13 is attached to the guide rail 2, the extension portion 542 is inclined so as to move away from the guide rail 2 as it extends downward D2 from the base end portion 542a.

[0061] The protrusion 541 is disposed at the end on the downward extension direction D2 side of the extension portion 542. The protrusion 541 is formed so as to protrude outward C2 from the extension portion 542. In a state where the drum housing 13 is attached to the guide rail 2, the protrusion 541 is formed so as to protrude from the extension portion 542 toward the fitting hole 25.

[0062] As shown in Fig. 11(b), the protrusion 541 has a gradient portion 543. As shown in Fig. 11(a), the gradient portion 543 is arranged on the side not facing the end portion 2b when the drum housing 13 is attached to the guide rail 2. As shown in Fig. 11(b), the gradient portion 543 is arranged on the outer direction C2 side of the protrusion 441. The gradient portion 543 is formed so as to extend from the upper end in the extending direction D1 of the protrusion 541 toward the lower extending direction D2. The gradient portion 443 is inclined so as to face the outer direction C2 as it goes toward the lower extending direction D2. As shown in Fig. 11(a), the gradient portion 543 is inclined so as to approach the fitting hole 25 as it approaches the end portion 2b. The tip portion 544 is the portion on the outermost C2 side of the gradient portion 543. The tip portion 544 is arranged inside the fitting hole 25 when the drum housing 13 is attached to the guide rail 2.

[0063] (Attachment of the drum housing 13 to the guide rail 2) When attaching the drum housing 13 to the guide rail 2, as shown in Fig. 13(a), the end portion 2b of the guide rail 2 is inserted into the rail insertion portion 52 of the drum housing 13.

[0064] When the end portion 2b of the guide rail 2 is inserted into the rail insertion portion 52, as shown in Fig. 13(b), the end portion 2b abuts against the gradient portion 543. Specifically, as shown in Fig. 13(a), the end portion 2b of the guide rail 2 has an end face 2d. The end 2d2 on the inner direction C1 side of the end face 2d abuts against the gradient portion 543.

[0065] When the end portion 2b is further moved deeper into the rail insertion portion 52, the gradient portion 543 slides with the end 2c2 while the fitting portion 54 bends. Then, when further moved, the tip portion 544 of the protrusion 541 slides with the surface 20d of the guide rail 2, and as shown in Fig. 13(c), the tip portion 544 fits into the fitting hole 25.

[0066] In this way, since a part of the fitting portion 54 fits into the fitting hole 25, it is possible to prevent the drum housing 13 from detaching from the guide rail 2 when assembling the window regulator 1.

[0067] When the window regulator 1 is attached to the vehicle, the tensions of the cables 6 and 7 act on the guide rail 2 and the drum housing 13. In the state where such tensions act, the fitting portion 54 is separated from the guide rail 2. Specifically, the protrusion 541 of the fitting portion 54 does not contact the edge 25e and the surface 20d of the fitting hole 25 and is separated from the edge 25e and the surface 20d as shown in FIGS. 9(b), 11(a) and 13(c). Also, as shown in FIG. 13(c), the extending portion 542 does not contact the surface 20d of the guide rail 2 and is separated from the surface 20d.

[0068] Therefore, even if vibration is transmitted to the drum housing 13, it is difficult for the fitting portion 54 to contact the guide rail 2, and generation of abnormal noise can be reduced.

[0069] Note that burrs may occur on the end 2d1 (an example of one end in the thickness direction) on the outer direction C2 side of the end face 2d of the guide rail 2 shown in FIG. 13(a) during the manufacturing process. The fitting portion 54 is arranged on the side opposite to the end 2d1 where burrs may occur. Thereby, it is possible to prevent the gradient portion 543 from contacting the burrs of the end 2d1 of the guide rail 2 and being damaged.

[0070] (Features, etc.) In the window regulator 1 of the present embodiment, in the state where the tensions of the cables 6 and 7 act on the cable guide 4, the fitting portion 44 is arranged separated from the guide rail 2. Thereby, the fitting portion 44 that prevents detachment of the cable guide 4 during assembly of the window regulator 1 is separated from the guide rail 2 in the state where the cables 6 and 7 are stretched after assembly. Therefore, even if vibration is transmitted to the cable guide 4, it is difficult for the fitting portion 44 to contact the guide rail 2, and generation of abnormal noise can be reduced.

[0071] In the window regulator 1 of the present embodiment, in a state where the tensions of the cables 6 and 7 act on the drum housing 13, the fitting portion 54 is arranged to be separated from the guide rail 2. Thereby, since the fitting portion 54 that prevents the separation of the drum housing 13 during the assembly of the window regulator 1 is separated from the guide rail 2 in a state where the cables 6 and 7 are tightened after the assembly, even if vibration is transmitted to the drum housing 13, it is difficult for the fitting portion 54 to contact the guide rail 2, and the generation of abnormal noise can be reduced.

[0072] In the window regulator 1 of the present embodiment, the extension portion 442 is arranged to be separated from the surface 20c of the guide rail 2, and in a state where the tensions of the cables 6 and 7 act on the cable guide 4, the protrusion portion 441 is separated from the edge 24e of the fitting hole 24.

[0073] In this way, since the extension portion 442 is provided to be separated from the surface 20c of the guide rail 2 and the protrusion portion 441 is separated from the edge 24e of the fitting hole 24, even if vibration is transmitted to the cable guide 4, it is difficult for the fitting portion 44 to contact the guide rail 2, and the generation of abnormal noise can be reduced.

[0074] In the window regulator 1 of the present embodiment, the extension portion 542 is arranged to be separated from the surface 20d of the guide rail 2, and in a state where the tensions of the cables 6 and 7 act on the drum housing 13, the protrusion portion 541 is separated from the edge 25e of the fitting hole 25.

[0075] In this way, since the extension portion 542 is provided to be separated from the surface 20d of the guide rail 2 and the protrusion portion 541 is separated from the edge 25e of the fitting hole 25, even if vibration is transmitted to the drum housing 13, it is difficult for the fitting portion 54 to contact the guide rail 2, and the generation of abnormal noise can be reduced.

[0076] In the window regulator 1 of the present embodiment, in a state where the cable guide 4 is attached to the guide rail 2, at least a part of the gradient portion 443 is on a side not facing the end portion 2a of the guide rail 2.

[0077] As a result, as the extending portion 442 bends and the gradient portion 443 slides on the guide rail 2, it becomes easier to attach the cable guide 4 to the guide rail 2.

[0078] In the window regulator 1 of the present embodiment, in a state where the drum housing 13 is attached to the guide rail 2, at least a part of the gradient portion 543 is on a side not facing the end portion 2 b of the guide rail 2.

[0079] As a result, as the extending portion 542 bends and the gradient portion 543 slides on the guide rail 2, it becomes easier to attach the cable guide 4 to the guide rail 2.

[0080] In the window regulator 1 of the present embodiment, when the extending portion 442 extends from the cable guide main body 41 toward the side opposite to the end portion 2 a of the guide rail 2 and is connected to the protruding portion 441, the gradient portion 443 is arranged on the side opposite to the extending portion 442 of the protruding portion 441, and when the extending portion 542 extends from the housing main body 51 toward the end portion 2 b side of the guide rail 2 and is connected to the protruding portion 541, the gradient portion 543 is arranged on the side of the extending portion 542 of the protruding portion 541.

[0081] As a result, as the extending portion 442 bends and the gradient portion 443 slides on the guide rail 2, it becomes easier to attach the cable guide 4 to the guide rail 2. Further, as the extending portion 542 bends and the gradient portion 543 slides on the guide rail 2, it becomes easier to attach the drum housing 13 to the guide rail 2.

[0082] In the window regulator 1 of the present embodiment, in a state where the cable guide 4 is attached to the guide rail 2, the extending portion 442 is inclined so as to move away from the guide rail 2 as it goes toward the protruding portion 441.

[0083] As a result, even if vibration is transmitted to the cable guide 4, it becomes difficult for the extending portion 442 to contact the guide rail 2, and generation of abnormal noise can be reduced.

[0084] In the window regulator 1 of the present embodiment, the extension portion 542 is inclined so as to move away from the guide rail 2 as it approaches the protrusion 541 in a state where the drum housing 13 is attached to the guide rail 2.

[0085] Accordingly, even if vibration is transmitted to the drum housing 13, it is difficult for the extension portion 542 to come into contact with the guide rail 2, and generation of abnormal noise can be reduced.

[0086] In the window regulator 1 of the present embodiment, the fitting portion 44 is disposed on the side opposite to the burr at one end 2c2 in the thickness direction of the end face 2c of the guide rail 2.

[0087] Accordingly, it is possible to prevent the gradient portion 443 from coming into contact with the end 2c2 of the guide rail 2 and being damaged.

[0088] In the window regulator 1 of the present embodiment, the fitting portion 54 is disposed on the side opposite to the burr at one end 2d1 in the thickness direction of the end face 2d of the guide rail 2.

[0089] Accordingly, it is possible to prevent the gradient portion 543 from coming into contact with the end 2d1 of the guide rail 2 and being damaged.
