Description

Technical Field

[0001] The present invention relates to an attachment structure and a window regulator.

Background Art

[0002] Examples of structures using a structure for attaching a cylindrical long member to an object to be attached include a window regulator.

[0003] A window regulator is a device for raising and lowering a window glass of a vehicle (see, for example, Patent Document 1). The window regulator shown in Patent Document 1 is a so-called rail-less window regulator in which a guide rail for slidingly guiding a carrier plate along the raising and lowering direction of the window glass is not provided. In such a window regulator, an outer casing that covers an inner cable that moves axially by rotational driving of a drum may be used between a drum housing and a cable guide.

[0004] For example, in Patent Document 1, the drum housing has a retaining portion and an engaging portion, and a guide portion is formed between the retaining portion and the engaging portion. An insertion hole through which the outer casing is inserted is formed in the retaining portion. In the guide portion, an outer storage groove is formed that extends from the end on the retaining portion side to the end on the engaging portion side and has a width wider than the outer diameter of the outer casing and narrower than the outer diameter of the terminal portion of the outer casing. When attaching the outer casing to the drum housing, the outer casing is passed through the insertion hole and guided to the engaging portion by the guide portion and engaged with the engaging portion. When the terminal portion of the outer casing is engaged with the engaging portion, the outer casing is housed in the outer storage groove.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, during transportation or the like, since the window regulator can be compactly assembled, an external force is likely to act on the terminal portion of the outer tube. In the mounting structure shown in Patent Document 1, for example, the movement of the terminal portion in the inner direction of the drum housing is not restricted. Therefore, when an external force acts in the inner direction of the drum housing, the terminal portion may float with respect to the drum housing and the engagement with the drum housing may be disengaged, and the terminal portion may come out of the drum housing.

[0007] An object of the present disclosure is to provide a mounting structure capable of suppressing the cylindrical long member from coming off the mounting target.

Means for Solving the Problems

[0008] The mounting structure of the present invention is a mounting structure for mounting a cylindrical long member to a mounting target, and the cylindrical long member includes a cylindrical long member body, an end body disposed at an end of the cylindrical long member body, and an end portion disposed on the end body and including an engaging portion that engages with the mounting target. The mounting target has an insertion portion into which the end portion is inserted along the axis of the end body, an engaged portion that is engaged with the engaging portion by rotation of the end portion about the axis, and an axial restriction portion disposed opposite to the engaging portion so as to restrict movement of the end portion in a direction along the axis.

[0009] The window regulator of the present invention includes a carrier plate that holds a window glass, an inner cable having one end connected to the carrier plate and pulling the carrier plate in a predetermined direction, a cable guide that changes the direction of the inner cable, a drum to which the other end of the inner cable is connected and that winds or unwinds the inner cable wound around the cable guide, a drum housing that rotatably supports the drum, and an outer casing that covers the inner cable positioned between the cable guide and the drum housing. The outer casing has an outer casing body, a cylindrical end body disposed at an end of the outer casing body, and an end portion including an engaging portion disposed on the end body and engaging with the drum housing. The drum housing has an insertion portion into which the end portion is inserted along the axis of the end body, an engaged portion engaged with the engaging portion by rotation of the end portion about the axis, and an axial restricting portion disposed opposite to the engaging portion so as to restrict movement of the end portion in a direction along the axis.

Advantages of the Invention

[0010] According to the mounting structure and the window regulator of the present invention, it is possible to suppress the cylindrical long member from coming off the mounting target.

Mode for Carrying Out the Invention

[0012] Hereinafter, a window regulator using the mounting structure according to the embodiment of the present invention will be described with reference to the drawings.

[0013] (Overview of Window Regulator) Figure 1 is a front view showing the configuration of the window regulator according to the embodiment. The window regulator 1 according to the present embodiment is disposed on a door panel of a vehicle door. The window regulator 1 moves a window glass of the vehicle up and down. The window regulator 1 is a rail-less type. In Figure 1, for convenience, the right direction on the paper surface is defined as the front, the left direction as the rear, and the vertical direction on the paper surface as the vertical direction for correspondence.

[0014] The window regulator 1 includes a carrier plate 2, an inner cable 3, a cable guide 4, a drum 5, a drum housing 6 (an example of an attachment target), and an outer casing 7 (an example of a cylindrical long member). The carrier plate 2 holds the window glass. The inner cable 3 is connected to the carrier plate 2 and pulls the carrier plate 2 in a predetermined direction. The cable guide 4 changes the direction of the inner cable 3. The drum 5 winds or pays out the inner cable 3 to which the inner cable 3 is connected and wound around the cable guide 4. The drum housing 6 rotatably supports the drum 5. The outer casing 7 covers the inner cable 3 located between the cable guide 4 and the drum housing 6.

[0015] (Carrier Plate 2) The carrier plate 2 holds the window glass. When the carrier plate 2 moves up and down, the window glass moves up and down to open and close.

[0016] In the window regulator 1 shown in Figure 1, two are provided in parallel in the front-rear direction with a predetermined interval therebetween, but it is not limited thereto, and for example, only one may be provided. When it is necessary to distinguish and explain the two carrier plates 2, the rear carrier plate 2 shown in Figure 1 is denoted as 2a, and the front carrier plate 2 is denoted as 2b.

[0017] (Inner Cable 3, Cable Guide 4) The inner cable 3 is a cable-like body made of, for example, a metal wire rod. The window regulator 1 shown in FIG. 1 has three inner cables 3. The three inner cables 3 are a raising cable 3a, an intermediate cable 3b, and a lowering cable 3c. When there is no need to distinguish the three inner cables, they are shown as the inner cable 3.

[0018] The raising cable 3a is connected to the carrier plate 2a and the drum 5. One cable end of the raising cable 3a is engaged with the drum 5, and the other cable end is engaged with the carrier plate 2a. The intermediate cable 3b is connected to the carrier plate 2a and the carrier plate 2b. One cable end of the intermediate cable 3b is engaged with the carrier plate 2a, and the other cable end is engaged with the carrier plate 2b. The lowering cable 3c is connected to the carrier plate 2b and the drum 5. One cable end of the lowering cable 3c is engaged with the carrier plate 2b, and the other cable end is engaged with the drum 5.

[0019] The cable guide 4 changes the routing direction of the inner cable 3. The cable guide 4 is fixed to, for example, the frame of the vehicle body. The cable guide 4 is, for example, a pulley. The window regulator 1 shown in FIG. 1 has four cable guides 4.

[0020] When it is necessary to distinguish and describe the four cable guides 4, the rear upper cable guide 4 shown in FIG. 1 is shown as 4a. The rear lower cable guide 4 shown in FIG. 1 is shown as 4b. The front upper cable guide 4 shown in FIG. 1 is shown as 4c. The front lower cable guide 4 shown in FIG. 1 is shown as 4d.

[0021] The cable guide 4a changes the direction of the raising cable 3a routed upward from one cable end engaged with the drum 5 from upward to downward. The other cable end of the raising cable 3a whose routing direction has been changed downward is engaged with the carrier plate 2a.

[0022] The cable guide 4b changes the direction of the intermediate cable 3b routed downward from one cable end engaged with the carrier plate 2a from downward to upward. The cable guide 4c changes the routing direction of the intermediate cable 3b redirected upward by the cable guide 4b from upward to downward. The other cable end of the intermediate cable 3b with the routing direction redirected downward is engaged with the carrier plate 2b.

[0023] The cable guide 4d changes the direction of the lowering cable 3c routed downward from one cable end engaged with the carrier plate 2b from downward to upward. The other cable end of the lowering cable 3c with the routing direction redirected upward is engaged with the drum 5.

[0024] In addition, in Fig. 1, although the carrier plate 2b seems to interfere with the drum housing 6 when the carrier plate 2b ascends, a space through which the carrier plate 2b can pass is provided on the back side of the drum housing 6 in the depth direction of the drawing, and the carrier plate 2b can move vertically without interfering with the drum housing 6.

[0025] (Drum 5, Drum housing 6) The drum 5 is connected to the inner cable 3, winds and pays out the inner cable 3, and moves the carrier plate 2 up and down. The drum 5 rotates by the drive of a motor. Each cable end of the hoisting cable 3a and the lowering cable 3c is connected to the drum 5. When the drum 5 rotates by the drive of the motor, the hoisting cable 3a and the lowering cable 3c are wound and paid out, and the carrier plates 2a, 2b move vertically.

[0026] The drum housing 6 rotatably houses the drum 5. The drum housing 6 houses a motor. The drum housing 6 is installed on the vehicle body frame. An outer casing 7 is attached to the drum housing 6. The attachment structure for attaching the outer casing 7 to the drum housing 6 will be described in detail later.

[0027] (Outer casing 7) The outer casing 7 is inserted into a part of the inner cable 3. The outer casing 7 is divided into three parts. The ascending cable 3a is inserted into the outer casing 7a between the cable guide 4a and the drum 5. Also, the intermediate cable 3b passes through the outer casing 7b between the cable guide 4b and the cable guide 4c. The descending cable 3c passes through the outer casing 7c between the cable guide 4d and the drum 5. One end of the outer casing 7a and one end of the outer casing 7c are attached to the drum housing 6 using the attachment structure 8.

[0028] (Attachment structure 8) The attachment structure 8 is a structure for attaching the outer casing 7 to the drum housing 6. In the window regulator 1 of the present embodiment, two attachment structures 8 are used. One attachment structure 8 (referred to as 8a when distinguishing) attaches the outer casing 7a to the drum housing 6. The other attachment structure 8 (referred to as 8b when distinguishing) attaches the outer casing 7c to the drum housing 6. Since the structures of the attachment structure 8a and the attachment structure 8b are the same, the configuration will be described using the attachment structure 8b as an example. FIG. 2 is a perspective view showing the attachment structure 8b.

[0029] The structure of the outer casing 7 side of the attachment structure 8 will be described, and then the structure of the drum housing 6 side will be described.

[0030] (Structure on the outer casing 7 side) The structure of the end portion 12 of the outer casing 7 attached to the drum housing 6 will be described.

[0031] FIG. 3 is a view showing an end portion on the side attached to the drum housing 6 of the outer casing 7c. The outer casing 7c has an outer casing main body 11 (an example of a cylindrical long member main body) and an end portion 12. The end portion 12 is disposed at the end of the outer casing main body 11 on the side of the drum housing 6. The end portion 12 is attached to the outer casing main body 11 by an attachment member 13. FIG. 4 is an exploded view of the outer casing main body 11, the end portion 12, and the attachment member 13. FIG. 5 is a cross-sectional view including the central axis A of the end portion 12.

[0032] As shown in FIG. 3, the end portion 12 includes an end portion main body 14 and an engaging portion 15. The end portion main body 14 is attached to the end of the outer casing main body 11. The engaging portion 15 engages with an engaged portion 33 described later.

[0033] As shown in FIGS. 4 and 5, the end portion main body 14 is a cylindrical member. A through hole 16 is formed in the end portion main body 14 along the central axis A. As shown in FIG. 5, the through hole 16 includes a first portion 21 into which the outer casing main body 11 is inserted and a second portion 22 through which an inner cable 3 (not shown) exposed from the outer casing main body 11 passes. The inner diameter of the second portion 22 is formed smaller than that of the first portion 21 on the side of the first portion 21. A stepped portion 23 is formed between the first portion 21 and the second portion 22.

[0034] The outer casing main body 11 inserted into the first portion 21 abuts against the stepped portion 23, and its insertion is restricted. The end portion main body 14 includes a small-diameter portion 24 and a large-diameter portion 25. The small-diameter portion 24 is formed on the side of the end portion main body 14 into which the outer casing main body 11 is inserted. The large-diameter portion 25 is disposed on the side opposite to the side into which the outer casing main body 11 of the small-diameter portion 24 is inserted.

[0035] The mounting member 13 is a clamping member. As shown in FIGS. 4 and 5, the mounting member 13 is cylindrical. With the outer casing body 11 inserted into the first portion 21, the mounting member 13 is fitted outside the small-diameter portion 24, whereby the end portion 12 is attached to the end of the outer casing body 11.

[0036] The engaging portion 15 is disposed on the side surface of the large-diameter portion 25. The engaging portion 15 protrudes outward from the side surface of the large-diameter portion 25. The engaging portion 15 has a substantially rectangular parallelepiped shape. As shown in FIG. 4, the opposing surfaces 15a of the engaging portion 15 in the circumferential direction D of the axis A are formed substantially parallel to the axis A. In the present embodiment, two engaging portions 15 are disposed on the large-diameter portion 25. The two engaging portions 15 are disposed so as to face each other with the axis A interposed therebetween.

[0037] (Structure on the drum housing 6 side) FIG. 6 is a perspective view showing the state of the drum housing 6 with the outer casing 7 removed from FIG. 2. In FIG. 6, the thickness direction of the drum housing 6 is indicated by W. Also, the front surface in FIG. 6 is shown as the first surface 6a, and the back surface is shown as the second surface 6b.

[0038] The drum housing 6 includes an insertion portion 31, an opening 32, an engaged portion 33, a rotation restricting portion 34, an axial direction restricting portion 35, a first convex portion 36, and a second convex portion 37. The end portion 12 of the outer casing 7 is inserted into the insertion portion 31 along the axis A through the opening 32. The insertion direction of the outer casing 7 into the insertion portion 31 coincides with the direction along the axis A. The engaged portion 33 can be engaged with the engaging portion 15 of the end portion 12.

[0039] (Insertion portion 31) FIG. 7 is a perspective view of the mounting structure 8b. FIG. 7 is a perspective view viewed from a direction different from that of FIG. 2. FIG. 8 is a cross-sectional view of the mounting structure 8b including the axis A. FIG. 9A is a cross-sectional view taken along the arrow between BB' in FIG. 7.

[0040] As shown in FIGS. 6 to 8, the insertion portion 31 includes a first housing portion 41 and a second housing portion 42. As shown in FIGS. 7 and 8, the first housing portion 41 houses the end body 14 of the end portion 12. As shown in FIGS. 7 and 9A, the first housing portion 41 has an opening 41a on the first surface 6a side. As shown in FIG. 6, the first housing portion 41 has a first inner wall 41b formed to face the cylindrical outer surface of the end body 14 and a second inner wall 41c perpendicular to the insertion direction (axis A direction) of the end body 14. The first inner wall 41b is curved so as to extend along the outer surface of the end body 14 from the opening 41a. The first inner wall 41b is formed around the axis A of the insertion portion 31. As shown in FIGS. 7 and 8, when the end portion 12 is inserted into the insertion portion 31, the tip 14a of the end body 14 abuts against the second inner wall 41c.

[0041] As shown in FIG. 7, the second housing portion 42 houses the engaging portion 15 of the end portion 12. The second housing portion 42 communicates with the first housing portion 41. As shown in FIG. 8, the second housing portion 42 is formed so as to protrude outward from the first inner wall 41b (an example of an inner wall) of the first housing portion 41 in a direction perpendicular to the axis A direction. In the present embodiment, the drum housing 6 has two second housing portions 42. The two second housing portions 42 are formed so as to face each other with the axis A interposed therebetween.

[0042] When the two second housing portions 42 are shown separately, the second housing portion 42 on the left side in FIG. 7 is denoted as 42a, and the second housing portion 42 on the right side is denoted as 42b. As shown in FIGS. 7 and 9, although not described in detail later, the engaged portion 33 is disposed in the second housing portion 42a.

[0043] FIG. 9B is the same figure as FIG. 9A, but in order to show the positions of the first housing portion 41, the second housing portion 42a, and the second housing portion 42b, each is shown by hatching. In addition, in order to make the positions of the first housing portion 41, the second housing portion 42a, and the second housing portion 42b easier to understand, the hatching indicating the cross-sectional portion described in FIG. 9A has been deleted. In FIG. 9B, the first housing portion 41 is hatched from the upper left to the lower right obliquely, and the second housing portions 42a and 42b are hatched from the upper right to the lower left obliquely. As shown in FIG. 9B, the second housing portion 42a is formed along the thickness direction W, has an opening 42aa in the first surface 6a, and has a bottom surface 42ab on the second surface 6b side in the thickness direction W. The opening 42aa is connected to the opening 41a of the first housing portion 41.

[0044] The second housing portion 42b is formed along the direction around the axis A. The second housing portion 42b has an opening 42ba in the first surface 6a. The second housing portion 42b curves from the opening 42ba toward the second surface 6b and along the periphery of the first housing portion 41 toward the second housing portion 42a. A rotation restricting portion 34, which will be described later, is disposed at the curved end. It can also be said that the second housing portion 42b is curved in the direction around the axis A.

[0045] (Opening 32) As shown in FIG. 6, the opening 32 is formed in the side wall 6c of the drum housing 6. The opening 32 is connected to the insertion portion 31. The opening 32 includes a first opening portion 43 and a second opening portion 44 as shown in FIG. 6.

[0046] When the end portion 12 is inserted into the insertion portion 31, the end portion main body 14 passes through the first opening portion 43. When the end portion 12 is inserted into the insertion portion 31, the engaging portion 15 passes through the second opening portion 44. Two second opening portions 44 are formed in the drum housing 6 so that the two engaging portions 15 can pass through. The second opening portion 44 is formed to protrude outward from the inner edge of the first opening portion 43. The two second opening portions 44 are formed to face each other with the first opening portion 43 interposed therebetween across the axis A. The two second opening portions 44 are formed along the thickness direction W.

[0047] (Engaged portion 33) As shown in FIGS. 7 and 9A, the engaged portion 33 is engaged with the engaging portion 15. The engaged portion 33 is disposed in the insertion portion 31. The engaged portion 33 is disposed in the second housing portion 42 of the insertion portion 31. The engaged portion 33 is formed along the thickness direction W of the drum housing 6. As shown in FIG. 9A, the engaged portion 33 is formed so as to protrude from the bottom surface 42ab of the second housing portion 42a toward the first surface 6a side along the thickness direction W.

[0048] The engaged portion 33 is engaged with the engaging portion 15 by the rotation of the end portion 12 in the direction along the axis A (described later).

[0049] As shown in FIG. 9A, the engaged portion 33 has a claw portion 51 and a support portion 52. The claw portion 51 is supported by the support portion 52. The support portion 52 extends from the bottom surface 42ab on the second surface 6b side of the second housing portion 42 toward the first surface 6a side along the thickness direction W. The claw portion 51 is disposed on the support portion 52. The claw portion 51 is formed from the support portion 52 toward the first housing portion 41 side. The claw portion 51 includes an engaged surface 51a and a guide surface 51b. The engaged surface 51a is engaged with the engaging portion 15. The guide surface 51b guides the engaging portion 15 into the second housing portion 42.

[0050] To explain the engagement of the engaging portion 15 with the engaged portion 33, the operation of attaching the outer casing 7c to the drum housing 6 will be described with reference to FIGS. 10 to 12.

[0051] As shown in FIG. 10, the end portion 12 of the outer casing 7c is disposed to face the opening 32. The end portion 12 is disposed to face the opening 32 such that the end body 14 faces the first opening portion 43 and the two engaging portions 15 face the two second opening portions 44. Also, the axis A that is the center of the end body 14 is disposed along the center of the first opening portion 43.

[0052] In this state, the end portion 12 is inserted into the insertion portion 31 through the opening 32 along the axis A direction. The end portion 12 is inserted until the tip 14a of the end body 14 abuts against the second inner wall 41c, as shown in FIG. 11.

[0053] FIG. 11 is a diagram showing a state where the end portion 12 is inserted into the insertion portion 31 through the opening 32. As described above, the state of the end portion 12 where the engaging portion 15 coincides with the second opening portion 44 when viewed along the direction of the axis A is an example of the first state.

[0054] Next, as shown in FIG. 11, the end portion 12 is rotated with respect to the drum housing 6 so that the engaging portion 15 disposed on the first surface 6a side moves toward the engaged portion 33 side (see arrow C). As a result, as shown in FIG. 12, the engaging portion 15 disposed on the first surface 6a side abuts against the claw portion 51. FIG. 13 is a cross-sectional view of the state shown in FIG. 12. The position of the cross-section in FIG. 13 is the same as that in FIG. 9A. When the end portion 12 is inserted into the insertion portion 31, the claw portion 51 disposed on the second surface 6b side moves along the curvature of the second housing portion 42 toward the first surface 6a side.

[0055] Subsequently, when the end portion 12 is further rotated in the direction of arrow C with respect to the drum housing 6, the engaging portion 15 moves while sliding on the guide surface 51b of the claw portion 51, and the support portion 52 bends toward the side opposite to the first housing portion 41 (see FIG. 14). As shown in FIG. 14, the position of the engaged portion 33 in the state where the engaging portion 15 is bent so as to be accommodated in the second housing portion 42 corresponds to the retracted position. When the engaging portion 15 gets over the guide surface 51b, the support portion 52 returns to its original position by the elastic force, and as shown in FIG. 9A, the engaged surface 51a is engaged by the engaging portion 15. The engaged surface 51a is disposed on the first surface 6a side of the surface 15a of the engaging portion 15. As described above, the state of the end portion 12 where the engaged surface 51a is engaged is an example of the second state.

[0056] In this way, the elastic force causes the engaged portion 33 to return to its original position, and the position of the engaged portion 33 in the state where the engaged surface 51a is disposed on the first surface 6a side of the engaging portion 15 corresponds to the engaged position. As the engaging portion 15 rotates, the engaged portion 33 transitions from the retracted position to the engaged position to guide the engaging portion 15 into the second housing portion 42a, and the engaging portion 15 engages the engaged portion 33.

[0057] By the above operation, the engaging portion 15 can be engaged with the engaged portion 33, and the outer casing 7b can be attached to the drum housing 6.

[0058] When the engaging portion 15 is engaged with the engaged portion 33 (the end portion 12 is in the second state), the second opening portion 44 is displaced from the position of the engaging portion 15 when viewed along the direction parallel to the axis A. That is, the second opening portion 44 is arranged along the thickness direction W. Further, the engaging portion 15 is rotatable only between the engaged portion 33 and the rotation restricting portion 34 described later, and cannot rotate to the position along the thickness direction W.

[0059] (Rotation restricting portion 34) The rotation restricting portion 34 restricts the rotation about the axis A of the end portion 12. As shown in FIG. 9A, the rotation restricting portion 34 is arranged on the axis A side with respect to the engaged portion 33. The rotation restricting portion 34 protrudes from the bottom surface on the second surface 6b side of the insertion portion 31 toward the first surface 6a side.

[0060] The rotation restricting portion 34 is arranged so as to sandwich the engaged portion 15 in a state where the engaged portion 33 is engaged and the engaged portion 15 is housed in the second housing portion 42.

[0061] After engaging the engaged portion 33 and housing the engaged portion 15 in the second housing portion 42, when the end portion 12 rotates in the C direction, the rotation is restricted by the engagement portion 15 abutting against the rotation restricting portion 34. Further, after engaging the engaged portion 33 and housing the engaged portion 15 in the second housing portion 42, when the end portion 12 rotates in the direction opposite to the C direction, the rotation is restricted by the engagement portion 15 abutting against the claw portion 51 of the engaged portion 33.

[0062] (Axial direction restricting portion 35) The axial direction restricting portion 35 is disposed opposite to the engaging portion 15 so as to restrict the movement of the end portion 12 in the direction along the axis A. In the present embodiment, the axial direction restricting portion 35 is an inner wall facing each other in a direction parallel to the axis A of the second accommodating portion 42. Specifically, the axial direction restricting portions 35 are provided at four locations. When distinguishing the four axial direction restricting portions 35, they are described as 35a, 35b, 35c, and 35d. As shown in FIG. 2, the axial direction restricting portion 35a is an inner wall on the insertion direction side (the second inner wall 41c side) of the second accommodating portion 42a. The axial direction restricting portion 35b is an inner wall on the side opposite to the insertion direction of the second accommodating portion 42a (the opening 32 side). The axial direction restricting portion 35c is an inner wall on the insertion direction side (the second inner wall 41c side) of the second accommodating portion 42b. The axial direction restricting portion 35d is an inner wall on the side opposite to the insertion direction of the second accommodating portion 42b (the opening 32 side).

[0063] When the end portion 12 moves toward the second inner wall 41c side along the axis A direction, the engaging portion 15 abuts against the axial direction restricting portion 35a or the axial direction restricting portion 35c, and the movement of the end portion 12 is restricted. When the end portion 12 moves toward the opening 32 side along the axis A direction, the engaging portion 15 abuts against the axial direction restricting portion 35b or the axial direction restricting portion 35d, and the movement of the end portion 12 is restricted.

[0064] (The first convex portion 36, the second convex portion 37) As shown in FIGS. 6 and 7, the first convex portion 36 is formed to protrude from the edge of the insertion portion 31. The first convex portion 36 is formed substantially parallel to the first surface 6a from the edge of the opening 41a of the first accommodating portion 41 toward the inside. The first convex portion 36 is disposed between the second accommodating portion 42 and the opening 32.

[0065] In the present embodiment, the drum housing 6 has a pair of first convex portions 36. The pair of first convex portions 36 are disposed opposite to each other in a direction perpendicular to the axis A. When inserting the end portion 12 into the insertion portion 31 through the opening 32, the engaging portion 15 disposed on the first surface 6a side of the end portion main body 14 passes between the pair of first convex portions 36.

[0066] The second convex portion 37 is formed to protrude from the edge of the insertion portion 31. The second convex portion 37 is formed substantially parallel to the first surface 6a from the edge of the opening 41a of the first housing portion 41 toward the inside. The second convex portion 37 is disposed between the second housing portion 42 and the second inner wall 41c.

[0067] In the present embodiment, the drum housing 6 has a pair of second convex portions 37. The pair of second convex portions 37 are disposed opposite to each other in a direction perpendicular to the axis A.

[0068] In a state where the end portion 12 is attached to the drum housing 6, the first convex portion 36 and the second convex portion 37 are disposed opposite to the side surface of the end portion body 14. Further, the second surface 6b side of the first convex portion 36 and the second convex portion 37 is formed to be curved along the side surface of the end portion body 14.

[0069] Even when the end portion 12 disposed in the insertion portion 31 attempts to move outward from the first surface 6a, the movement of the end portion 12 is restricted by the end portion body 14 coming into contact with the first convex portion 36 or the second convex portion 37.

[0070] (Features, functions, effects, etc.) In the attachment structure 8 of the present embodiment, the rotation of the end portion 12 of the outer casing 7 about the axis A is restricted by the engagement between the engaging portion 15 and the engaged portion 33, and the movement in the direction along the axis A is restricted by the axial restriction portion 35 coming into contact with the engaging portion 15. Therefore, it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0071] In the attachment structure 8 of the present embodiment, the engaged portion 33 is disposed outside the first inner wall 41b in a direction perpendicular to the axis A. Therefore, even when an external force acts on the end portion 12, the movement of the end portion body 14 is restricted by the first inner wall 41b of the first housing portion 41, so that the engaging portion 15 is difficult to move. Therefore, it is difficult to release the engagement between the engaging portion 15 and the engaged portion 33, and it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0072] In the mounting structure 8 of the present embodiment, the rotation of the end portion 12 about the axis A is restricted by the engagement portion 15 coming into contact with the engaged portion 33 or the rotation restricting portion 34. Therefore, it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0073] In the mounting structure 8 of the present embodiment, the movement of the end portion 12 in the direction parallel to the axis A is restricted by the engagement portion 15 coming into contact with the inner wall of the second housing portion 42. Therefore, it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0074] In the mounting structure 8 of the present embodiment, even when the end portion 12 moves so as to come off the insertion portion 31 in the direction perpendicular to the axis A due to the action of an external force, the first convex portion 36 and the second convex portion 37 come into contact with the end portion main body 14, and it is possible to prevent the end portion 12 from coming off the insertion portion 31. Therefore, it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0075] In the mounting structure 8 of the present embodiment, the second opening portion 44 is displaced from the position of the engagement portion 15 in the state of being engaged with the engaged portion 33 in the direction parallel to the axis A. For this reason, even when an external force acts on the end portion 12 in the direction of pulling out from the insertion portion 31, the engagement portion 15 comes into contact with the edge of the opening 32, and it is possible to prevent the cylindrical long member from coming off the attachment target. Thereby, it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0076] In the mounting structure 8 of the present embodiment, the end portion 12 of the outer casing 7 transitions from the first state in which it is inserted into the insertion portion 31 of the drum housing 6 to the second state in which the engagement portion 15 is guided by the guide surface 51b and engaged with the engaged surface 51a by rotating the outer casing 7 by a predetermined amount with respect to the drum housing 6. For this reason, the outer casing 7 can be attached to the drum housing 6 with a simple operation.

[0077] In the window regulator 1 of the present embodiment, the rotation of the outer casing 7 about the axis A at the end 12 is restricted by the engagement with the engaged portion 33, and the movement in the direction along the axis A is restricted by the axial restriction portion 35. Therefore, it is possible to prevent the outer casing 7 from coming off the drum housing 6.

[0078] (Other embodiments) As described above, one embodiment of the present disclosure has been described. However, the present disclosure is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present disclosure.

[0081] (B) In the above embodiment, a pair of engaging portions 15 are provided at the end 12. However, only one engaging portion 15 may be provided. In that case, for the two second accommodating portions 42, it is sufficient that only the second accommodating portion 42 in which the engaged portion 33 is arranged is provided. Also, for the two second opening portions 44, it is sufficient that the second opening portion 44 is provided only on the first surface 6a side. Further, two or more engaging portions 15 may be provided. In that case, for the second accommodating portion 42, it is sufficient that it is provided at a position corresponding to the positional relationship of each engaging portion 15, and for the second opening portion 44, it is sufficient that it is provided at a position corresponding to the positional relationship of each engaging portion.

[0082] (C) In the above embodiment, the axial restraint portion 35 also serves as the inner wall of the second housing portion 42, but the axial restraint portion 35 may be arranged as a separate part inside the second housing portion 42. In short, the axial restraint portion 35 only needs to be able to restrict the movement of the end portion 12 along the axis A direction.

[0083] (D) In the above embodiment, the first convex portion 36 and the second convex portion 37 are arranged, but only the first convex portion 36 or the second convex portion 37 may be provided. Also, two first convex portions 36 and second convex portions 37 are provided, but only one may be provided.

[0084] (E) In the above embodiment, the end portion 12 is attached to the outer casing main body 11 by the attachment member 13, but the end portion 12 may be directly attached to the outer casing main body 11 by, for example, an adhesive or the like.

[0085] (F) In the window regulator 1 of the above embodiment, two carrier plates 2 were provided, but the present invention is not limited to such a configuration, and only one carrier plate 2 may be provided.
