Description

[Technical Field]

[0001] The present invention relates to a sun visor for a vehicle. [Background technology]

[0002] Some vehicle sun visors include a resin body and a plate-shaped mirror attached to the body. For example, in Patent Document 1, a surrounding wall is formed on the body to limit the area where the mirror is to be placed, and a receiving edge is formed at the front end of the surrounding wall to receive the periphery of the mirror. The front side of the periphery of the mirror is abutted against the receiving edge, and the rear side of the periphery of the mirror is held by a fixed claw and a movable claw. The fixed claw and the movable claw are formed on the body so as to face each other, and the movable claw is designed to be elastically deflectable in the plane direction of the mirror.

[0003] When attaching a mirror to a body, first insert the mirror into the area surrounded by the surrounding wall from the rear of the body, and insert the lower edge of the mirror between the lower receiving edge and the fixed claw. Then, move the upper edge of the mirror forward while pressing the movable claw. This causes the movable claw to elastically bend in the direction of the mirror's surface. This causes the upper edge of the mirror to move over the movable claw and be inserted between the upper receiving edge and the movable claw. In this way, the mirror is attached to the body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 3074553 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, there is a risk that the mirror may rattle relative to the body depending on the thickness of the mirror and the dimensions between the receiving edge and the fixed and movable claws. Therefore, in vehicle sun visors, it is desired to improve productivity while suppressing the occurrence of rattle of the mirror relative to the body. [Means for solving the problem]

[0006] Various aspects for solving the above problems will be described below. [Aspect 1] With a resin body, a plate-shaped mirror provided on the body, the mirror has a mirror periphery; The body is a holder for holding the peripheral edge of the mirror; a rib that holds the mirror peripheral edge portion together with the holding portion, The rib is an extension portion extending in a thickness direction of the mirror outside the peripheral edge portion of the mirror; a contact portion bent relative to the extension portion and contacting a portion of the mirror peripheral edge portion opposite to the holding portion, The sun visor for a vehicle, wherein the abutting portion is fixed to the extending portion via a welding portion in a state where the abutting portion is bent relative to the extending portion.

[0007] According to this, the abutment portion of the rib abuts against a portion of the mirror peripheral edge that is located opposite the holding portion. The extension portion and the abutment portion are fixed via a welded portion, so the position of the abutment portion is maintained. Therefore, the rib, together with the holding portion, can stably hold the mirror peripheral edge, thereby preventing the mirror from rattling relative to the body. The abutment portion is welded to the extension portion while being bent relative to the extension portion. This makes it easier to automate the process of fixing the abutment portion to the extension portion compared to, for example, bonding the abutment portion to the extension portion using an adhesive. As a result, it is possible to improve the productivity of vehicle sun visors while preventing the mirror from rattling relative to the body.

[0008] [Aspect 2] The vehicle sun visor described in [Aspect 1] is characterized in that, before the abutment portion is bent toward the extension portion, the surface of the abutment portion located on the mirror side does not protrude toward the mirror side more than the surface of the extension portion located on the mirror side.

[0009] According to this, before the abutment portion is bent relative to the extension portion, the surface of the abutment portion facing the mirror does not protrude further toward the mirror than the surface of the extension portion facing the mirror. Therefore, before the abutment portion is bent relative to the extension portion, when placing the mirror on the holder portion, even if the mirror is placed from above the holder portion, the peripheral edge of the mirror does not interfere with the abutment portion. Therefore, the mirror can be placed on the holder portion from one direction, making it easier to automate the assembly of the vehicle sun visor.

[0010] [Aspect 3] the rib has a notch formed between the extension portion and the abutment portion, The vehicle sun visor according to [Aspect 1] or [Aspect 2], wherein the abutment portion is bent relative to the extension portion using the notch as a base point.

[0011] This makes it easier for the abutment portion bent relative to the extension portion to abut against the portion of the mirror peripheral edge opposite the holding portion, compared to when the rib does not have a notch, and as a result, the rib can hold the mirror peripheral edge together with the holding portion more stably.

[0012] [Aspect 4] The notch is a first surface extending from the extension portion toward the abutment portion; a second surface extending from the contact portion and continuing to an end of the first surface located on the contact portion side, The vehicle sun visor according to [Aspect 3], wherein the angle formed between the first surface and the second surface before the contact portion is bent relative to the extension portion is an acute angle.

[0013] According to this, the angle formed between the first surface and the second surface before the abutting portion is bent relative to the extending portion is an acute angle, so that the abutting portion can be easily bent relative to the extending portion.

[0014] [Aspect 5] The vehicle sun visor according to [Aspect 4], wherein the welded portion welds the first surface and the second surface together when the abutting portion is bent relative to the extending portion.

[0015] This allows the extension portion and the abutting portion to be stably fixed together via the welded portion. [Aspect 6] A vehicle sun visor described in any one of [Aspect 1] to [Aspect 5], characterized in that the end of the abutment portion located opposite the extension portion and the surface located on the mirror side are tapered so as to gradually move away from the mirror as they approach the tip of the abutment portion.

[0016] According to this, when placing the mirror on the holder from above before the abutting portion is bent relative to the extension portion, the peripheral edge of the mirror is less likely to interfere with the tip of the abutting portion, making it easier to place the mirror on the holder from one direction, further facilitating automation of the assembly of the vehicle sun visor. [Effects of the Invention]

[0017] According to the present invention, it is possible to improve the productivity of vehicle sun visors while suppressing the occurrence of rattle of the mirror relative to the body. [Brief explanation of the drawings]

[0019] Hereinafter, a specific embodiment of a vehicle sun visor will be described with reference to FIGS. <General configuration of a vehicle sun visor> As shown in Fig. 1, the vehicle sun visor 10 includes a resin body 11, a plate-shaped mirror 30, and a mirror cover 40. The body 11 includes a visor main body 12 and a mirror trim 13. The vehicle sun visor 10 is attached, for example, to the front portion of the ceiling of the vehicle. The vehicle sun visor 10 is used to prevent light from outside the vehicle from shining directly into the eyes of passengers inside the vehicle.

[0020] The visor body 12 is formed by assembling two shell-shaped halves together. The visor body 12 is hollow. The visor body 12 is flat and plate-shaped. When viewed from above, the visor body 12 has a rectangular shape. The visor body 12 is disposed relative to the vehicle so that the longitudinal direction of the visor body 12 coincides with the vehicle width direction.

[0021] The vehicle sun visor 10 has an arm 14. The arm 14 is cylindrical and bent into a substantially L-shape. A first end of the arm 14 is supported, for example, on the ceiling of the vehicle via a bracket 15. A second end of the arm 14 is inserted into a bearing portion (not shown) of the visor body 12.

[0022] The visor body 12 is rotatable relative to the vehicle ceiling around the arm 14 as a rotation center. The visor body 12 is rotatable relative to the vehicle ceiling between a use position and a storage position. When the visor body 12 is positioned at the use position, it is disposed facing the windshield. When the visor body 12 is positioned at the use position, it prevents light from outside the vehicle from directly shining into the eyes of passengers inside the vehicle. When the visor body 12 is positioned at the use position, one of the two half bodies constituting the visor body 12 is positioned on the passenger side, and the other of the two half bodies is positioned on the windshield side of the vehicle. When the visor body 12 is positioned at the storage position, it is disposed along the vehicle ceiling. When the visor body 12 is positioned at the storage position, one of the two half bodies constituting the visor body 12 is positioned on the vehicle ceiling side, and the other of the two half bodies is positioned on the opposite side from the ceiling.

[0023] A recess 16 is formed on the edge of the visor body 12. The vehicle sun visor 10 also has a cylindrical support shaft 17. The support shaft 17 is provided on the visor body 12 so as to cross the recess 16 in the longitudinal direction of the visor body 12. The support shaft 17 can be engaged with a hook (not shown) provided on the ceiling of the vehicle. With the support shaft 17 engaged with the hook, the visor body 12 can rotate relative to the ceiling of the vehicle around the arm 14 as the rotation center.

[0024] The visor body 12 has a mounting opening 18. The mounting opening 18 is formed in one of the two half bodies that make up the visor body 12. The mounting opening 18 has a rectangular hole shape in a plan view. The longitudinal direction of the mounting opening 18 coincides with the longitudinal direction of the visor body 12. The mirror trim 13 is mounted in the mounting opening 18.

[0025] The visor body 12 has a pair of body rails 19. The pair of body rails 19 are continuous with the mounting opening 18. The extending direction of the pair of body rails 19 coincides with the longitudinal direction of the mounting opening 18. The pair of body rails 19 extend parallel to each other from the mounting opening 18 in the longitudinal direction of the visor body 12. The pair of body rails 19 are arranged inside the visor body 12. The pair of body rails 19 are a slide mechanism that slidably supports the mirror cover 40.

[0026] <Mirror trim 13> 2 and 3, the mirror trim 13 has a rectangular frame shape in a plan view. The mirror trim 13 has a flange wall 21, a pair of side walls 22, a slide opening 23, and a stopper portion 24. For ease of explanation, the mirror 30 is shown in FIG. 2 by a two-dot chain line.

[0027] The flange wall 21 has a rectangular frame shape. The flange wall 21 has a first flange plate 211, a second flange plate 212, a third flange plate 213, and a fourth flange plate 214. The first flange plate 211, the second flange plate 212, the third flange plate 213, and the fourth flange plate 214 are each shaped like a long, narrow plate. The first flange plate 211 and the second flange plate 212 extend parallel to each other in the longitudinal direction of the mirror trim 13. The third flange plate 213 and the fourth flange plate 214 extend parallel to each other in the lateral direction of the mirror trim 13. The third flange plate 213 connects a first longitudinal end of the first flange plate 211 to a first longitudinal end of the second flange plate 212. The fourth flange plate 214 connects a second longitudinal end of the first flange plate 211 to a second longitudinal end of the second flange plate 212. The first flange plate 211, the second flange plate 212, the third flange plate 213, and the fourth flange plate 214 are connected to one another with their thickness directions aligned with one another. The first flange plate 211, the second flange plate 212, the third flange plate 213, and the fourth flange plate 214 define an opening 25 in the mirror trim 13. The opening 25 in the mirror trim 13 is in the shape of a rectangular hole. The opening 25 in the mirror trim 13 exposes the mirror 30.

[0028] The pair of side walls 22 are shaped like elongated plates. The pair of side walls 22 are shaped like thin, flat plates. The pair of side walls 22 stand up from the flange wall 21. The pair of side walls 22 extend parallel to each other in the longitudinal direction of the mirror trim 13. The longitudinal direction of each side wall 22 coincides with the longitudinal direction of the mirror trim 13. One of the pair of side walls 22 stands up from a portion of the first flange plate 211 that is located on one side in the thickness direction. The other of the pair of side walls 22 stands up from a portion of the second flange plate 212 that is located on one side in the thickness direction. The pair of side walls 22 stand up from the flange wall 21 with the thickness directions of the side walls 22 coinciding with each other. In the following description, the side wall 22 standing from the first flange plate 211 may be referred to as the "first side wall 221," and the side wall 22 standing from the second flange plate 212 may be referred to as the "second side wall 222."

[0029] The slide opening 23 is open between the pair of side walls 22 on one side in the longitudinal direction of the mirror trim 13. Specifically, the slide opening 23 is a space defined by a first end in the longitudinal direction of the first side wall 221, a first end in the longitudinal direction of the second side wall 222, and the third flange plate 213.

[0030] The stopper portion 24 has a narrow plate shape. The stopper portion 24 has a thin, flat plate shape. The stopper portion 24 stands up from the flange wall 21. The stopper portion 24 stands up from a portion of the fourth flange plate 214 that is located on one side in the thickness direction. The longitudinal direction of the stopper portion 24 coincides with the lateral direction of the mirror trim 13. A first lateral end of the stopper portion 24 is connected to a second lateral end of the first side wall 221. A second lateral end of the stopper portion 24 is connected to a second lateral end of the second side wall 222. Therefore, the stopper portion 24 blocks the space between the pair of side walls 22 on the other longitudinal side of the mirror trim 13.

[0031] <Holding part> The mirror trim 13 has a pair of retaining portions 50. Therefore, the body 11 has the retaining portions 50. The pair of retaining portions 50 are shaped like elongated plates. The pair of retaining portions 50 stand upright from each of the pair of side walls 22. Specifically, one of the pair of retaining portions 50 stands upright from the first side wall 221. The other of the pair of retaining portions 50 stands upright from the second side wall 222. The pair of retaining portions 50 extend parallel to each other in the longitudinal direction of the mirror trim 13. The longitudinal direction of each retaining portion 50 coincides with the longitudinal direction of the mirror trim 13. The pair of retaining portions 50 face each other in the lateral direction of the mirror trim 13. The pair of retaining portions 50 stand upright from each of the side walls 22 with the thickness directions of each retaining portion 50 coinciding with each other. The thickness direction of each retaining portion 50 is perpendicular to the thickness direction of each of the side walls 22. In the following description, the holding portion 50 standing from the first side wall 221 may be referred to as the "first holding portion 51," and the holding portion 50 standing from the second side wall 222 may be referred to as the "second holding portion 52."

[0032] The first retaining portion 51 stands upright from the first side wall 221 toward the second side wall 222. The first retaining portion 51 is spaced apart from the end of the first side wall 221 opposite to the first flange plate 211. Therefore, a portion of the first side wall 221 extends further away from the first flange plate 211 than the first retaining portion 51.

[0033] The second retaining portion 52 stands upright from the second side wall 222 toward the first side wall 221. The second retaining portion 52 is spaced apart from the end of the second side wall 222 opposite the second flange plate 212. Therefore, a portion of the second side wall 222 extends further away from the second flange plate 212 than the second retaining portion 52.

[0034] <Mirror> As shown in FIG. 3 , the mirror 30 is flat. In a plan view, the mirror 30 is rectangular. The mirror 30 has a mirror peripheral edge 31. The mirror peripheral edge 31 has a first peripheral edge 311, a second peripheral edge 312, a third peripheral edge 313, and a fourth peripheral edge 314. The first peripheral edge 311 and the second peripheral edge 312 extend parallel to each other in the longitudinal direction of the mirror 30. The third peripheral edge 313 and the fourth peripheral edge 314 extend parallel to each other in the lateral direction of the mirror 30. The third peripheral edge 313 connects a first longitudinal end of the first peripheral edge 311 to a first longitudinal end of the second peripheral edge 312. The fourth peripheral edge 314 connects a second longitudinal end of the first peripheral edge 311 to a second longitudinal end of the second peripheral edge 312.

[0035] The mirror 30 is disposed relative to each holding portion 50 with the thickness direction of the mirror 30 coinciding with the thickness direction of each holding portion 50. Specifically, the mirror 30 is disposed relative to each holding portion 50 with the first peripheral portion 311 overlapping the first holding portion 51 in the thickness direction of the first holding portion 51 and the second peripheral portion 312 overlapping the second holding portion 52 in the thickness direction of the second holding portion 52.

[0036] <Mirror cover> As shown in Fig. 1 , the mirror cover 40 is in the shape of a rectangular plate. The mirror cover 40 is slidable relative to the mirror trim 13 between a closed position where it covers the mirror 30 and an open position where it exposes the mirror 30. The mirror cover 40 covers the mirror 30 by protruding from the inside of the visor body 12 into the opening 25 of the mirror trim 13. The mirror cover 40 exposes the mirror 30 by retracting from the opening 25 of the mirror trim 13 into the inside of the visor body 12. When the mirror cover 40 retracts from the opening 25 of the mirror trim 13 into the inside of the visor body 12, the mirror cover 40 is guided inside the visor body 12 by a pair of body rails 19.

[0037] The mirror cover 40 is configured to be slidable in and out of the mirror trim 13 through the slide opening 23. The opening direction and closing direction of the mirror cover 40 coincide with the longitudinal direction of the visor body 12. The third flange plate 213 is a portion of the mirror trim 13 located on the side of the mirror cover 40 in the opening direction. The fourth flange plate 214 is a portion of the mirror trim 13 located on the side of the mirror cover 40 in the closing direction.

[0038] <Rib> As shown in FIGS. 2, 3, and 4, the mirror trim 13 has a rib 60. Therefore, the body 11 has the rib 60. The rib 60 has an extending portion 61 and an abutting portion 62. The mirror trim 13 has four abutting portions 62. Each abutting portion 62 has an elongated plate shape. Each abutting portion 62 has a thin, flat plate shape. Two of the four abutting portions 62 protrude from an end of the first side wall 221 located opposite the first flange plate 211. The remaining two of the four abutting portions 62 protrude from an end of the second side wall 222 located opposite the second flange plate 212. In the following description, the abutting portion 62 protruding from the first side wall 221 may be referred to as a "first abutting portion 621," and the abutting portion 62 protruding from the second side wall 222 may be referred to as a "second abutting portion 622."

[0039] The longitudinal direction of each first abutment portion 621 coincides with the longitudinal direction of the first side wall 221. The first abutment portions 621 are arranged at predetermined intervals in the longitudinal direction of the first side wall 221. Each first abutment portion 621 is bent toward the second side wall 222 from an end portion of the first side wall 221 located opposite the first flange plate 211. Each first abutment portion 621 abuts against a portion of the first peripheral portion 311 of the mirror 30 located opposite the first holding portion 51. As a result, each first abutment portion 621 holds the first peripheral portion 311 together with the first holding portion 51.

[0040] The portions of the first side wall 221 that overlap with the first contact portions 621 in the standing direction relative to the first flange plate 211 are extending portions 61 that extend in the thickness direction of the mirror 30 outside the first peripheral edge portion 311. Therefore, the first side wall 221 has two extending portions 61. Each first contact portion 621 is bent at an end of each extending portion 61 located opposite the first holding portion 51, and comes into contact with a portion of the first peripheral edge portion 311 located opposite the first holding portion 51.

[0041] The longitudinal direction of each second abutment portion 622 coincides with the longitudinal direction of the second side wall 222. The second abutment portions 622 are arranged at predetermined intervals in the longitudinal direction of the second side wall 222. Each second abutment portion 622 faces each first abutment portion 621 in the short direction of the mirror trim 13. Each second abutment portion 622 is bent toward the first side wall 221 from an end portion of the second side wall 222 opposite the second flange plate 212. Each second abutment portion 622 abuts against a portion of the second peripheral edge portion 312 of the mirror 30 opposite the second holding portion 52. As a result, each second abutment portion 622 holds the second peripheral edge portion 312 together with the second holding portion 52.

[0042] The portions of the second side wall 222 that overlap with the second contact portions 622 in the standing direction relative to the second flange plate 212 are extending portions 61 that extend in the thickness direction of the mirror 30 outside the second peripheral edge portion 312. Therefore, the second side wall 222 has two extending portions 61. Each second contact portion 622 is bent at an end of each extending portion 61 located opposite the second holding portion 52, and comes into contact with a portion of the second peripheral edge portion 312 located opposite the second holding portion 52.

[0043] As described above, the mirror trim 13 has four ribs 60. Each rib 60 has an extending portion 61 and an abutting portion 62. The extending portion 61 extends in the thickness direction of the mirror 30 outside the mirror peripheral portion 31. The abutting portion 62 is bent relative to the extending portion 61 and abuts against a portion of the mirror peripheral portion 31 that is located on the opposite side from the holding portion 50.

[0044] As shown in Fig. 4, the extending portion 61 has an extending surface 61a. The extending surface 61a is a surface of the extending portion 61 that faces the mirror 30. The extending surface 61a is flat. The abutting portion 62 has an abutting surface 62a. The abutting surface 62a is a surface of the abutting portion 62 that faces the mirror 30. The abutting surface 62a is flat.

[0045] 5 and 6 show the state before the abutment portion 62 is bent relative to the extending portion 61. As shown in FIGS. 5 and 6, before the abutment portion 62 is bent relative to the extending portion 61, the abutment surface 62a and the extending surface 61a extend parallel to each other. The abutment surface 62a is disposed at a position farther away from the mirror 30 in the short direction of the mirror trim 13 than the extending surface 61a. Therefore, before the abutment portion 62 is bent relative to the extending portion 61, the abutment surface 62a does not protrude further toward the mirror 30 than the extending surface 61a. In this way, before the abutment portion 62 is bent relative to the extending portion 61, the surface of the abutment portion 62 facing the mirror 30 does not protrude further toward the mirror 30 than the surface of the extending portion 61 facing the mirror.

[0046] As shown in Figure 5, in the first abutment portion 621 and the second abutment portion 622 that face each other in the short-side direction of the mirror trim 13, the distance L1 between the abutment surface 62a of the first abutment portion 621 and the abutment surface 62a of the second abutment portion 622 is longer than the length L2 of the mirror 30 in the short-side direction.

[0047] As shown in FIG. 6 , the abutment portion 62 has a tapered surface 62b. The tapered surface 62b is a surface located on the mirror 30 side and closer to the tip of the abutment portion 62 than the abutment surface 62a. Therefore, the tapered surface 62b is an end portion of the abutment portion 62 located opposite the extending portion 61 and is a surface located on the mirror 30 side. The tapered surface 62b gradually moves away from the mirror 30 from the abutment surface 62a toward the tip of the abutment portion 62. Therefore, the tip of the abutment portion 62 has a tapered shape. In this way, the end portion of the abutment portion 62 located opposite the extending portion 61 and the surface located on the mirror 30 side has a tapered shape that gradually moves away from the mirror 30 toward the tip of the abutment portion 62.

[0048] The rib 60 has a notch 70. The notch 70 is formed between the extending portion 61 and the abutting portion 62. The notch 70 has a first surface 71 and a second surface 72. The first surface 71 is continuous with the extending surface 61a. The first surface 71 extends from the extending surface 61a toward the abutting portion 62. Therefore, the first surface 71 extends from the extending portion 61 toward the abutting portion 62. The first surface 71 extends obliquely with respect to the extending direction of the extending surface 61a. The first surface 71 extends in a direction away from the mirror 30 as it moves away from the extending surface 61a.

[0049] The second surface 72 is continuous with the end of the first surface 71 located on the abutment portion 62 side. The second surface 72 is continuous with the abutment surface 62a. The second surface 72 extends from the abutment surface 62a toward the extending portion 61. Therefore, the second surface 72 extends from the abutment portion 62 and is continuous with the end of the first surface 71 located on the abutment portion 62 side. The second surface 72 extends obliquely with respect to the extending direction of the abutment surface 62a. The second surface 72 extends in a direction away from the mirror 30 as it moves away from the abutment surface 62a. The second surface 72 extends obliquely with respect to the extending direction of the first surface 71. The extending direction of the first surface 71 and the extending direction of the second surface 72 intersect with each other. Before the abutting portion 62 is bent relative to the extending portion 61, the angle θ1 formed between the first surface 71 and the second surface 72 is an acute angle.

[0050] As shown in FIG. 7 , the abutment portion 62 is bent relative to the extending portion 61, using the notch 70 as a base point. The abutment portion 62 is fixed to the extending portion 61 via the welding portion 80 when bent relative to the extending portion 61. The welding portion 80 welds the first surface 71 and the second surface 72 together when the abutment portion 62 is bent relative to the extending portion 61. In this manner, the extending portion 61 and the abutment portion 62 are fixed via the welding portion 80. The rib 60, together with the retaining portion 50, holds the mirror peripheral portion 31. Therefore, the retaining portion 50 holds the mirror peripheral portion 31. In this manner, the mirror 30 is provided on the mirror trim 13. Therefore, the mirror 30 is provided on the body 11.

[0051] <Mirror assembly procedure> Next, a description will be given of the procedure for assembling the mirror 30. Figures 8, 9, 10 and 11 show the assembly procedure for assembling the mirror 30 to the mirror trim 13 in order.

[0052] 8, when assembling the mirror 30 to the mirror trim 13, first, the mirror trim 13, before the abutment portion 62 is bent relative to the extension portion 61, is positioned so that the abutment portion 62 faces upward. Then, the mirror 30 is moved from above the holding portion 50 toward the holding portion 50. At this time, because the abutment surface 62a does not protrude further toward the mirror 30 than the extension surface 61a, the mirror peripheral portion 31 does not interfere with the abutment portion 62 even when the mirror 30 is positioned from above the holding portion 50.

[0053] 9, the mirror 30 that has passed inside the abutment portion 62 and the extension portion 61 is placed relative to the holder 50. Specifically, the mirror 30 is placed relative to the holder 50 in a state in which the first peripheral portion 311 of the mirror 30 is placed on the first holder 51 and the second peripheral portion 312 of the mirror 30 is placed on the second holder 52.

[0054] 10, the abutment portion 62 is then bent relative to the extension portion 61, using the notch 70 as a base point. As a result, the abutment portion 62 bent relative to the extension portion 61 comes into contact with a portion of the mirror peripheral portion 31 that is located on the opposite side from the holding portion 50.

[0055] As shown in FIG. 11 , a welding jig 81 is then pressed against the upper part of the abutment portion 62. Examples of welding methods include ultrasonic welding, heat welding, and high-frequency welding. As a result, a welded portion 80 is formed between the first surface 71 and the second surface 72, and the first surface 71 and the second surface 72 are welded via the welded portion 80. In this way, the extension portion 61 and the abutment portion 62 are fixed via the welded portion 80. As a result, the rib 60 holds the mirror peripheral portion 31 together with the holding portion 50. In this way, the mirror 30 is assembled to the mirror trim 13.

[0056] [Operation of the embodiment] Next, the operation of this embodiment will be described. The contact portion 62 of the rib 60 contacts a portion of the mirror peripheral edge 31 that is located on the opposite side from the retaining portion 50. The extending portion 61 and the contact portion 62 are fixed together via the welding portion 80, so the posture of the contact portion 62 is maintained. Therefore, the rib 60 stably holds the mirror peripheral edge 31 together with the retaining portion 50, thereby suppressing rattle of the mirror 30 relative to the mirror trim 13.

[0057] [Effects of the embodiment] The above embodiment can provide the following effects. (1) The body 11 has a holder 50 that holds the mirror peripheral edge 31, and a rib 60 that holds the mirror peripheral edge 31 together with the holder 50. The rib 60 has an extending portion 61 that extends in the thickness direction of the mirror 30 outside the mirror peripheral edge 31, and a contact portion 62 that is bent relative to the extending portion 61 and abuts against a portion of the mirror peripheral edge 31 that is located on the opposite side from the holder 50. The abutting portion 62 is fixed to the extending portion 61 via a welding portion 80 in a state where it is bent relative to the extending portion 61. As a result, the abutting portion 62 of the rib 60 abuts against a portion of the mirror peripheral edge 31 that is located on the opposite side from the holder 50. Since the extending portion 61 and the abutting portion 62 are fixed via the welding portion 80, the orientation of the abutting portion 62 is maintained. Therefore, the rib 60, together with the holding portion 50, can stably hold the mirror peripheral portion 31, thereby preventing the mirror 30 from rattling relative to the body 11. Then, with the abutting portion 62 bent relative to the extending portion 61, the abutting portion 62 is welded to the extending portion 61. This makes it easier to automate the process of fixing the abutting portion 62 to the extending portion 61 compared to, for example, using an adhesive. As a result, it is possible to prevent the mirror 30 from rattling relative to the body 11 while improving the productivity of the vehicle sun visor 10.

[0058] (2) Before the abutting portion 62 is bent relative to the extending portion 61, the surface of the abutting portion 62 facing the mirror 30 does not protrude further toward the mirror 30 than the surface of the extending portion 61 facing the mirror 30. Therefore, before the abutting portion 62 is bent relative to the extending portion 61, the mirror peripheral portion 31 does not interfere with the abutting portion 62 even if the mirror 30 is placed on the holding portion 50 from above. Therefore, the mirror 30 can be placed on the holding portion 50 from one direction, which makes it easier to automate the assembly of the vehicle sun visor 10.

[0059] (3) The rib 60 has a notch 70 formed between the extending portion 61 and the abutting portion 62. The abutting portion 62 is bent relative to the extending portion 61 using the notch 70 as a base point. This makes it easier to bring the abutting portion 62, bent relative to the extending portion 61, into abutment with a portion of the mirror peripheral portion 31 located on the opposite side from the holding portion 50, compared to when the rib 60 does not have the notch 70. As a result, the rib 60 can hold the mirror peripheral portion 31 together with the holding portion 50 more stably.

[0060] (4) Before the contact portion 62 is bent relative to the extending portion 61, the angle θ1 formed between the first surface 71 and the second surface 72 is an acute angle. This makes it easy to bend the contact portion 62 relative to the extending portion 61.

[0061] (5) The welded portion 80 welds the first surface 71 and the second surface 72 together when the abutting portion 62 is bent relative to the extending portion 61. This allows the extending portion 61 and the abutting portion 62 to be stably fixed together via the welded portion 80.

[0062] (6) The end of the abutting portion 62 opposite the extending portion 61 and facing the mirror 30 is tapered so as to gradually move away from the mirror 30 toward the tip of the abutting portion 62. As a result, before the abutting portion 62 is bent relative to the extending portion 61, when the mirror 30 is placed on the holding portion 50, the mirror peripheral portion 31 is less likely to interfere with the tip of the abutting portion 62 even if the mirror 30 is placed from above the holding portion 50. Therefore, the mirror 30 can be easily placed on the holding portion 50 from one direction, which further facilitates automation of the assembly of the vehicle sun visor 10.

[0063] (7) Because the rib 60 holds the mirror peripheral portion 31 together with the retaining portion 50, there is no need for a separate member for holding the mirror peripheral portion 31 together with the retaining portion 50. This reduces the number of parts in the vehicle sun visor 10.

[0064] (8) In order for the rib 60 to stably hold the mirror peripheral portion 31 together with the holding portion 50, the extension portion 61 and the abutment portion 62 are fixed together with the welding portion 80. This allows the rib 60 to stably hold the mirror peripheral portion 31 together with the holding portion 50 without applying an excessive load to the mirror peripheral portion 31.

[0065] (9) The abutting portion 62 is bent relative to the extending portion 61, and the abutting portion 62 is brought into abutment with a portion of the mirror peripheral portion 31 located on the opposite side from the retaining portion 50, and the abutting portion 62 is fixed to the extending portion 61 via the welding portion 80. Therefore, since there is no need to perform special processing on the mirror 30 in order to assemble the mirror 30 to the mirror trim 13, the assembly work of the mirror 30 to the mirror trim 13 can be easily performed.

[0066] [Example of change] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0067] In the embodiment, before the abutment portion 62 is bent relative to the extension portion 61, the surface of the abutment portion 62 facing the mirror 30 may be flush with the surface of the extension portion 61 facing the mirror 30.

[0068] In the embodiment, before the abutment portion 62 is bent relative to the extension portion 61, the surface of the abutment portion 62 facing the mirror 30 may protrude further toward the mirror 30 than the surface of the extension portion 61 facing the mirror 30.

[0069] In the embodiment, the angle θ1 between the first surface 71 and the second surface 72 before the contact portion 62 is bent relative to the extension portion 61 may be a right angle. In the embodiment, the angle θ1 formed between the first surface 71 and the second surface 72 before the contact portion 62 is bent relative to the extension portion 61 may be an obtuse angle.

[0070] In the embodiment, the rib 60 may be configured such that the notch 70 is not formed between the extending portion 61 and the abutting portion 62. In this case, the welded portion 80 only needs to weld the abutting portion 62 and the extending portion 61 together in a state in which the abutting portion 62 is bent relative to the extending portion 61.

[0071] In the embodiment, the contact portion 62 may not have the tapered surface 62 b. In other words, the end of the contact portion 62 located on the opposite side to the extending portion 61 and facing the mirror 30 may not be tapered so as to gradually move away from the mirror 30 toward the tip of the contact portion 62.

[0072] In the embodiment, the portions of the first side wall 221 that overlap with the first abutment portions 621 in the standing direction relative to the first flange plate 211 are the extending portions 61, but this is not limited to this. For example, a portion of the first side wall 221 does not have to extend beyond the first retaining portion 51 toward the opposite side of the first flange plate 211. The first retaining portion 51 may also stand up from the end of the first side wall 221 on the opposite side of the first flange plate 211. Even in this case, it is sufficient that the extending portions 61 that constitute the ribs 60 extend outside the mirror peripheral portion 31 in the thickness direction of the mirror 30.

[0073] In the embodiment, the portions of the second side wall 222 that overlap with the second abutment portions 622 in the standing direction relative to the second flange plate 212 are the extending portions 61, but this is not limited to this. For example, a portion of the second side wall 222 does not have to extend further away from the second flange plate 212 than the second retaining portion 52. The second retaining portion 52 may stand up from the end of the second side wall 222 on the side opposite to the second flange plate 212. Even in this case, it is sufficient that the extending portions 61 that constitute the rib 60 extend in the thickness direction of the mirror 30 outside the mirror peripheral edge portion 31.

[0074] In the embodiment, the mirror trim 13 has a pair of elongated plate-shaped retaining portions 50, but this is not limiting and, for example, the mirror trim 13 may have a frame-shaped retaining portion 50. In short, the shape and configuration of the retaining portion 50 are not particularly limited as long as it is capable of holding the mirror peripheral portion 31 together with the rib 60.

[0075] In the embodiment, the mirror trim 13 may have, for example, one or three or more abutment portions 62 protruding from the first side wall 221. The mirror trim 13 may also have, for example, one or three or more abutment portions 62 protruding from the second side wall 222. In short, the number of ribs 60 may be changed as appropriate.

[0076] In the embodiment, the body 11 does not have to have the mirror trim 13. For example, one of the two half bodies constituting the visor main body 12 may have the retaining portion 50 and the rib 60. In short, it is sufficient that the body 11 has the retaining portion 50 and the rib 60.

[0077] In the embodiment, the shape of the mirror 30 may be changed as appropriate. In this case, the shapes of the mirror trim 13 and the mirror cover 40 may also be changed as appropriate according to the shape of the mirror 30. In the embodiment, the shape of the visor body 12 may be changed as appropriate. [Explanation of symbols]
