Problems to be solved by the invention

However, since the outer diameter of the spring is smaller than the outer diameter of the flange portion of the end portion, a gap is generated between the inner wall of the end accommodating portion and the outer peripheral surface of the spring. Due to this gap, there is a case where a shaft offset occurs between the spring and the end portion, and the spring collides with the inner wall of the housing portion, thereby generating abnormal noise.

The purpose of the present disclosure is to provide a cable attachment structure and a window opening/closing regulator that can reduce the occurrence of abnormal noise by suppressing the axial displacement of a spring.

As shown in fig. 7 and 9, the end member 42 of the cable 7 and the spring 9 are accommodated in the lowering cable end accommodating portion 22. As shown in fig. 8A, 8B and 9, the inner space of the lowering cable end housing portion 22 is formed in a polygonal prism shape. The inner space of the lowering cable end housing portion 22 is formed in a polygonal shape in cross section perpendicular to the axis P as the center axis. The inner space of the lowering cable end housing 22 is preferably formed in an octagon shape, for example. In addition, octagons in this specification are intended to include not only complete octagons but also general octagons that appear to be reminiscent of octagons.

As shown in fig. 8B, the lowering cable end housing portion 22 includes an end surface 61, an inner side surface 62, an opening 63, and a penetration portion 64. As shown in fig. 7, the cable 7 extends from the end surface 61 in the downward direction A2. The end surface 61 is disposed on the downward A2 side. The end surface 61 is disposed perpendicularly to the vertical direction a.

The inner surface 62 is disposed to extend from the periphery of the end surface 61 in the upward direction A1. The inner side 62 has a side portion 621 forming sides of a polygon in cross-section. In the present embodiment, since it is formed in an octagon shape, eight side portions 621 are provided. Eight side portions 621 are arranged parallel to the axis P. In addition, only a part of the eight side portions 621 is denoted by a reference numeral. The opening 63 is provided at an end of the inner surface 62 opposite to the end surface 61. The penetrating portion 64 penetrates the wall of the lowering cable end accommodating portion 22. The through portion 64 is formed to the outer edge of the end face 61 through the center of the end face 61, and is formed to the opening 63 from the outer edge through one side face portion 621 of the inner side face 62 along the up-down direction a. The side surface portion of the side surface portion 621, which will be described later, on which the through portion 64 is formed is denoted as a side surface portion 621a. The side surface portion 621a is a surface on the inner direction C1 side of the inner side surface 62. The side surface portion 621a is arranged perpendicularly with respect to the width direction C.

The cable 7 is mounted in the lowering cable end housing 22 by inserting the end member 42 and the spring 9 from the opening 63 while passing the cable body 41 through the through portion 64.

(Cable end housing portion for raising 21)

Next, the raising cable end housing portion 21 for mounting the cable 6 will be described. Fig. 10A is an enlarged view of the vicinity of the raising cable end housing portion 21 in fig. 4C. Fig. 10B is a perspective view of the raising cable end housing portion 21 viewed from the inner direction C1 side. Fig. 10C is a perspective view of the raising cable end housing portion 21 viewed from the outer direction C2 side. Fig. 10D is a cross-sectional view perpendicular to the front-rear direction B. The position of the cross section of fig. 10D is the same as the three-dimensional cross section between EEs of fig. 4A. Fig. 11 is a perspective sectional view of EE of fig. 4A. Fig. 11 is a view in which the end member 32 and the spring 8 are added to fig. 10D.

As shown in fig. 7, the raising cable end housing 21 houses the end member 32 of the cable 6 and the spring 8. As shown in fig. 10A to 10C, the inner space of the raising cable end housing portion 21 is formed in a polygonal shape in cross section perpendicular to the axis Q as the center axis thereof. The section of the raising cable end housing portion 21 is preferably formed in an octagon shape, for example. In addition, octagons in this specification are intended to include not only complete octagons but also general octagons that appear to be reminiscent of octagons.

As shown in fig. 10B, the raising cable end housing portion 21 has an end surface 71, an inner side surface 72, an opening 73, and a penetration portion 74. As shown in fig. 11, the cable 6 extends from the end face 71 in the upward direction A1. The end face 71 is disposed on the upward A1 side. The end surface 71 is disposed perpendicularly to the vertical direction a.

The inner surface 72 is disposed to extend from the periphery of the end surface 71 in the downward direction A2. The opening 73 is provided at an end of the inner surface 72 opposite to the end surface 71. The penetrating portion 74 penetrates the wall of the raising cable end housing portion 21. The through portion 74 is formed to the outer edge of the end surface 61 through the center of the end surface 71, and is formed to the opening 63 from the outer edge through the inner side surface 72 along the vertical direction a.

The cable body 31 is inserted into the distal member 32 and the spring 8 through the through portion 74 from the opening 73, whereby the cable 6 is mounted in the raising cable end housing portion 21.

As shown in fig. 10B and 10C, the raising cable end housing portion 21 has a first housing portion 51 and a second housing portion 52. As shown in fig. 11, the first housing portion 51 is slidable with respect to the seat portion 34. The first housing portion 51 is a portion on the downward A2 side of the raising cable end housing portion 21. The cross-sectional area of the first housing portion 51 along the up-down direction a is constant. The center axis of the first housing portion 51 coincides with the center axis of the end member 32 in the state where the cable 6 is attached to the first housing portion 51. This coincident axis is denoted as axis Q. The outer peripheral edge of the seat 34 slides on the inner surface 75 of the first housing 51.

The first housing portion 51 has a polygonal cross-sectional shape perpendicular to the axis Q. As shown in fig. 10B and 10C, the inner side 75 has side portions 751 forming a plurality of sides of a polygonal column. In the present embodiment, since it is formed in an octagon shape, eight side portions 751 are provided. Eight side portions 751 are arranged parallel to axis Q. In addition, only a part of the eight side portions 751 is denoted by a reference numeral. An opening 73 is formed in an end portion of the first housing portion 51 on the opposite side from the second housing portion 52.

As shown in fig. 10B and 10C, the second housing portion 52 is disposed on the side (upward A1 side) of the first housing portion 51 from which the cable 6 extends. As shown in fig. 11, the second housing portion 52 restricts movement of the spring 8 in a direction perpendicular to the axis Q, and has a smaller cross-sectional area perpendicular to the axis Q than the first housing portion 51.

As shown in fig. 10B and 10C, the second housing portion 52 has an end surface 71 and an inner side surface 76. The end surface 71 is formed with a first through portion 77 through which the cable 6 is inserted. The first through portion 77 penetrates the end surface 71 in the up-down direction a. The first through portion 77 is formed to the outer edge of the end surface 71 through the center of the end surface 71. The first through portion 77 is formed in a groove shape. In the present embodiment, the first through portion 77 is formed from the vicinity of the center of the end surface 71 toward the inner direction C1. The end surface 71 restricts movement of the end member 32 to a predetermined or more side (upward A1 side) connected to the cable 6. The end surface 71 is disposed perpendicularly to the vertical direction a.

The inner side 76 is formed along the axis o from the outer edge of the end face 71. As shown in fig. 11, the inner surface 76 is disposed around the spring 8 in a state where the cable 6 is attached to the raising cable end housing portion 21. The inner surface 76 of the second housing portion 52 and the inner surface 75 of the first housing portion 51 constitute the inner surface 72 of the raising cable end housing portion 21.

The second housing portion 52 has a polygonal cross-sectional shape perpendicular to the axis o. As shown in fig. 10B and 10C, the inner side 76 has a side portion 761 forming sides of a cross-sectional polygon. Side portion 761 forms a plurality of sides of the polygon prism. In the present embodiment, since it is formed in an octagon shape, eight side portions 761 are provided. In addition, only some of the eight side portions 761 are denoted by reference numerals.

As shown in fig. 10A to 10D, the inner surface 76 has an inclined portion 78. The inclined portion 78 is formed at one side portion 761a of the plurality of side portions 761. As shown in fig. 11, the inclined portion 78 is inclined so as to approach the axis Q toward the end face 71 on the end face 71 side of the side face portion 761a (one example of the face) of the inner side face 76 to which the end member 32 approaches when tension is generated in the cable 6.

The side surface portion 761a formed with the inclined portion 78 is a surface on the inner direction C1 side of the plurality of side surface portions 761. All side portions 761 except the side portion 761a are formed parallel to the axis Q. Each of the side portions 751 of the first housing portion 51 is provided with a respective side portion 751 on the end face 71 side of each of the side portions 761 in a corresponding manner to each of the side portions 761. Each of the side portions 761 other than the side portion 761a is arranged in parallel with each of the side portions 751. Side portion 761 is disposed closer to axis Q than side portion 751. Accordingly, as shown in fig. 10A to 10C, a step 771 is formed between the side portion 761 and the side portion 751.

As shown in fig. 10B, a second through portion 79 is formed in the side portion 761a. The second through portion 79 penetrates the side surface portion 761a in the width direction C. The second through portion 79 is connected to the first through portion 77 and is formed in a groove shape along the axis Q. The second through portion 79 is disposed at the center of the side portion 761a in the front-rear direction B. As shown in fig. 10A and 10C, the inclined portion 78 is disposed so as to sandwich the second through portion 79. The inclined portions 78 are disposed on both sides of the second through portion 79 in the front-rear direction B.

As shown in fig. 10C, the second through portion 79 is formed from the side surface portion 761a to a side surface portion 751a disposed on the opposite side of the side surface portion 761a from the end surface 61. The second through portion 79 communicates with the opening 73. The first through portion 77 and the second through portion 79 constitute the above-described through portion 74.

As shown in fig. 11, when tension is generated in the cable 6, the seat 8a of the end portion on the end face 71 side of the spring 8 comes into contact with the inclined portion 78 as the end member 32 moves. When tension is applied to the cable 6, the spring 8 is also likely to move in the arrow G direction side (the direction side between the arrow A1 and the arrow C1) in which the through portion 74 is formed along with the bending of the rail 2, but the movement of the spring 8 is restricted because the spring 8 is in contact with the inclined portion 78. This suppresses the inclination of the spring 8 and thus the rotation of the spring 8, and thus the occurrence of a collision sound by which the seat 8a of the spring 8 collides with the end surface 71 can be reduced.

(characteristics, etc.)

In the window regulator 1 of the present embodiment, since the second housing portion 52 is provided in the raising cable end housing portion 21, the axial displacement of the spring 8 can be suppressed, and thus the occurrence of abnormal noise can be reduced. Further, by providing the inclined portion 78 in the second housing portion 52, a part of the seat 8a at one end of the spring 8 is in contact with the inclined portion 78, and thus the inclination of the spring 8 and the rotation of the spring 8 can be suppressed. Therefore, the occurrence of collision noise between the end surface 71 of the raising cable end housing portion 21 and the seat 8a of the spring 8 can be reduced.

In the window regulator 1 of the present embodiment, the second housing portion 52 is formed in a polygonal cross-sectional shape perpendicular to the axis Q. This suppresses the rotation of the spring 8, and further reduces the occurrence of collision noise.

In the window regulator 1 of the present embodiment, by providing the inclined portion 78 at the side portion 761a where the second through portion 79 is formed, movement of the spring 8 in the direction in which the cable 6 is pulled can be suppressed, and therefore, occurrence of axial misalignment can be reduced.
