Sun visor for vehicle

Abstract

To suppress application of a predetermined external force, which has acted on a sun visor body, to a vehicle body side fixation part via a support shaft even when the external force acts on the sun visor body.SOLUTION: A cylindrical core 31 includes a fragile part 50. A coating resin 41 is formed with a slit 49 through which the fragile part 50 is exposed to the outside. Since the fragile part 50 is exposed to the outside via the slit 49, for example, as compared to a case where the fragile part 50 is coated with the coating resin 41, when a predetermined external force acts on a support shaft 30 and a stress applied to the cylindrical core 31 is applied to the fragile part 50, the cylindrical core 31 is easy to break with the fragile part 50 as a start point. At the same time as when the cylindrical core 31 breaks with the fragile part 50 as a start point, the coating resin 41 is also easy to break with the slit 49 as a start point. In this manner, the cylindrical core 31 and the coating resin 41 are simultaneously made to be broken.SELECTED DRAWING: Figure 2

Description

[Technical field]

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

[0002] For example, as disclosed in Patent Document 1, a sun visor for a vehicle includes a sun visor body, a vehicle body side fixing part, and a support shaft. The support shaft supports the sun visor body relative to the vehicle body side fixing part. The vehicle body side fixing part is made of resin from the viewpoint of appearance from inside the vehicle cabin.

[0003] In such a vehicle sun visor, for example, when a lighting device is provided on the sun visor body, wiring for supplying power to the lighting device needs to be routed inside the support shaft, so a cylindrical support shaft is sometimes used for the vehicle sun visor.

[0004] Here, for example, if the cylindrical support shaft is made of metal, the support shaft can be shaped into a desired shape simply by bending the cylindrical support shaft. On the other hand, when a metallic support shaft is used, there is a problem that the external appearance from inside the vehicle cabin is deteriorated. Therefore, it is conceivable to use a resin support shaft, but when the cylindrical support shaft is made of resin, it is difficult to form the support shaft into a desired shape.

[0005] In view of this, it is conceivable to form the spindle from a metallic cylindrical core and a resin coating that covers the outer circumferential surface of the cylindrical core. By using such a spindle, it is possible to easily form the cylindrical spindle into a desired shape and to improve the external appearance of the spindle from inside the vehicle cabin. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 4693600 Summary of the Invention [Problem to be solved by the invention]

[0007] However, when a predetermined external force acts on the sun visor body, the external force acting on the sun visor body may be applied to the vehicle body side fixing part via the support shaft. In this case, the vehicle body side fixing part may break, and the broken part of the vehicle body side fixing part may be exposed in the vehicle cabin or may be scattered in the vehicle cabin. Therefore, it is desired to prevent the external force acting on the sun visor body from being applied to the vehicle body side fixing part via the support shaft even if a predetermined external force acts on the sun visor body. [Means for solving the problem]

[0008] Various aspects for solving the above problems will be described below. [Aspect 1] A sun visor body, A resin fixed part on the vehicle body side; a cylindrical support shaft that supports the sun visor body relative to the vehicle body side fixing portion, The support shaft is A metal cylinder and A sun visor for a vehicle having a coating resin that covers an outer peripheral surface of the cylindrical core, The cylindrical core has a fragile portion, The sun visor for a vehicle, wherein the coating resin has a slit for exposing the fragile portion to the outside.

[0009] According to this, since the fragile portion is exposed to the outside through the slit, when a predetermined external force acts on the support shaft and stress is applied to the cylindrical core, the cylindrical core is more likely to break from the fragile portion as a starting point, compared to when the fragile portion is covered with a coating resin, for example. And, at the same time that the cylindrical core breaks from the fragile portion as a starting point, the coating resin is also likely to break from the slit as a starting point. Therefore, by simultaneously breaking the cylindrical core and the coating resin, even if a predetermined external force acts on the sun visor body, it is possible to prevent the external force acting on the sun visor body from being applied to the vehicle body side fixing portion via the support shaft.

[0010] [Aspect 2] an insertion hole into which the support shaft is inserted is formed in the vehicle body side fixing portion, The insertion hole is open to a vehicle interior side surface of the vehicle body side fixing portion, The vehicle sun visor according to [Aspect 1], wherein the support shaft is inserted into the insertion hole with the weak portion and the slit positioned on the same plane as the passenger compartment side surface.

[0011] This allows the damaged portions of the core and the coating resin to be positioned on the same plane as the vehicle interior side surface of the vehicle body side fixing part, which makes it easier to prevent the damaged portions of the core and the coating resin from protruding from the vehicle interior side surface of the vehicle body side fixing part into the vehicle cabin.

[0012] [Aspect 3] an insertion hole into which the support shaft is inserted is formed in the vehicle body side fixing portion, The insertion hole is open to a vehicle interior side surface of the vehicle body side fixing portion, The vehicle sun visor described in [Aspect 1] is characterized in that the support shaft is inserted into the insertion hole with the weak portion and the slit positioned in a position inserted inside the insertion hole relative to the vehicle interior side surface.

[0013] According to this, the location where the core and the coating resin are damaged can be located at a position where they are inserted inside the insertion hole with respect to the vehicle interior side surface of the vehicle body side fixing part. As a result, the location where the core and the coating resin are damaged does not protrude into the vehicle interior from the vehicle interior side surface of the vehicle body side fixing part, making it easier to prevent the damaged parts of the core and the coating resin from protruding from the vehicle interior side surface of the vehicle body side fixing part.

[0014] [Aspect 4] the weakened portion is an edge formed by crushing a part of the cylindrical core, The sun visor for a vehicle according to any one of [Aspect 1] to [Aspect 3], wherein the edge extends in a direction intersecting with the axial direction of the cylindrical core.

[0015] In this way, the edge formed by crushing a part of the cylindrical core so as to extend in a direction intersecting the axial direction of the cylindrical core is suitable as a weak part. In addition, since the weak part can be formed in the cylindrical core by simply crushing a part of the cylindrical core, the structure of the cylindrical core can be simplified.

[0016] [Aspect 5] A sun visor for a vehicle according to any one of [Aspect 1] to [Aspect 4], characterized in that a locking portion is provided in a portion of the cylindrical core located on the opposite side of the sun visor body from the fragile portion, the locking portion being engaged with the coating resin to prevent axial movement of the cylindrical core relative to the coating resin.

[0017] According to this, for example, when the cylindrical core breaks starting from the weak portion, the locking portion can prevent the cylindrical core from moving in the axial direction relative to the coating resin. As a result, for example, when the cylindrical core breaks starting from the weak portion, it is possible to prevent the broken portion of the cylindrical core from protruding farther into the vehicle cabin than the broken portion of the coating resin. Effect of the Invention

[0018] According to this invention, even if a predetermined external force acts on the sun visor body, the external force acting on the sun visor body can be prevented from being applied to the vehicle body side fixed portion via the support shaft. [Brief description of the drawings]

[0020] Hereinafter, a specific embodiment of a sun visor for a vehicle will be described with reference to Figs. <Outline of vehicle sun visor configuration> 1, the vehicle sun visor 10 includes a sun visor body 11, a vehicle body side fixing part 20, and a support shaft 30. The vehicle sun visor 10 is attached, for example, to the front of the ceiling of the vehicle. The vehicle sun visor 10 is used to prevent light from outside the vehicle from directly shining on the eyes of passengers in the vehicle cabin.

[0021] <Sun visor body> The sun visor body 11 is made of a resin material. The sun visor body 11 has a first half body 12 and a second half body 13. The first half body 12 and the second half body 13 are shell-shaped. The sun visor body 11 is configured by assembling the first half body 12 and the second half body 13 to each other. The first half body 12 and the second half body 13 are overlapped and joined to each other. The sun visor body 11 is hollow. The sun visor body 11 is flat plate-shaped. The sun visor body 11 is rectangular in plan view. The sun visor body 11 is disposed with respect to the vehicle so that the longitudinal direction of the sun visor body 11 coincides with the vehicle width direction.

[0022] The sun visor body 11 has a notch 16. The notch 16 is formed in the long side edge portion 11a of the sun visor body 11. The vehicle sun visor 10 also has a cylindrical support shaft 17. The support shaft 17 is provided to the sun visor body 11 so as to bridge over portions located on both sides in the longitudinal direction of the sun visor body 11 at the inner edge of the notch 16. The support shaft 17 can be engaged with a hook (not shown) provided on the ceiling of the vehicle.

[0023] A bearing portion 18 is provided inside the sun visor body 11. The bearing portion 18 is located inside the sun visor body 11, closer to the long side edge portion 11a. The bearing portion 18 is disposed at a position overlapping the notch 16 in the longitudinal direction of the sun visor body 11. The bearing portion 18 is configured to rotatably support a support shaft 30 inserted into the sun visor body 11 from a side edge 11b located in the longitudinal direction of the sun visor body 11. Since such a bearing portion 18 is already known, a detailed description of its configuration will be omitted.

[0024] <Fixed to vehicle body> The vehicle body side fixing part 20 is provided on the ceiling of the vehicle. The vehicle body side fixing part 20 is made of resin. The vehicle body side fixing part 20 is a resin bracket. By using a resin material for the vehicle body side fixing part 20 in this manner, the external appearance of the vehicle body side fixing part 20 from inside the vehicle compartment is improved. The vehicle body side fixing part 20 has a vehicle compartment side surface 20a located on the vehicle compartment side.

[0025] 2, an insertion hole 21 is formed in the vehicle body side fixing part 20. The support shaft 30 is inserted into the insertion hole 21. The insertion hole 21 opens to a vehicle interior side surface 20a of the vehicle body side fixing part 20. The vehicle interior side surface 20a is, for example, a curved surface that is convex toward the vehicle interior.

[0026] The vehicle body side fixing part 20 has a plurality of locking claws 22. Each locking claw 22 is provided in an opening located on the opposite side of the insertion hole 21 from the vehicle interior side surface 20a in the vehicle body side fixing part 20. Each locking claw 22 protrudes from an opening edge located on the opposite side of the insertion hole 21 from the vehicle interior side surface 20a toward the axis of the insertion hole 21. Each locking claw 22 is elastically deformable in a direction approaching and receding from the axis of the insertion hole 21. Each locking claw 22 is configured by forming, for example, a four-part split groove in the opening located on the opposite side of the insertion hole 21 from the vehicle interior side surface 20a in the vehicle body side fixing part 20.

[0027] <Spindle> As shown in FIG. 1, the support shaft 30 is cylindrical. The support shaft 30 supports the sun visor body 11 relative to the vehicle body side fixing part 20. The support shaft 30 is bent in a substantially L-shape. A first end of the support shaft 30 is supported by the vehicle body side fixing part 20. A second end of the support shaft 30 is supported by the bearing part 18. The support shaft 30 supports the sun visor body 11 relative to the vehicle body side fixing part 20. The sun visor body 11 is provided with a lighting device (not shown). Wiring for supplying power to the lighting device is arranged inside the support shaft 30.

[0028] <Usage and storage locations> The sun visor body 11 is rotatable with respect to the vehicle body side fixed part 20 around the support shaft 30. With the support shaft 17 engaged with the hook, the sun visor body 11 is rotatable with respect to the vehicle body side fixed part 20 around a part supported by the bearing part 18 of the support shaft 30 as the rotation center. The sun visor body 11 is rotatable with respect to the vehicle body side fixed part 20 between a use position and a storage position. When the sun visor body 11 is located at the use position, it is disposed facing the windshield. When the sun visor body 11 is located at the use position, it prevents light from outside the vehicle from directly hitting the eyes of the passenger in the vehicle cabin. When the sun visor body 11 is located at the use position, the first half body 12 is located on the passenger side, and the second half body 13 is located on the vehicle windshield side. When the sun visor body 11 is located at the storage position, it is disposed along the ceiling of the vehicle. When the sun visor body 11 is in the storage position, the first half body 12 is located on the ceiling side of the vehicle, and the second half body 13 is located on the opposite side to the ceiling.

[0029] <Details of shaft structure> As shown in Fig. 3 and Fig. 4, the spindle 30 has a cylindrical core 31 and a coating resin 41. In Fig. 3, the coating resin 41 is indicated by a two-dot chain line. The cylindrical core 31 is made of metal. The coating resin 41 covers the outer peripheral surface of the cylindrical core 31. The coating resin 41 is integrated with the cylindrical core 31 by being insert molded with the cylindrical core 31. Since the coating resin 41 covers the outer peripheral surface of the cylindrical core 31 in this way, the appearance of the spindle 30 from inside the vehicle cabin is improved.

[0030] <Cylinder core> As shown in FIG. 3, the cylindrical core 31 is bent in a substantially L-shape. The cylindrical core 31 is hollow. The cylindrical core 31 is formed by bending a cylindrical metal tube. The cylindrical core 31 has a first extending portion 32, a second extending portion 33, and a bending portion 34. The first extending portion 32 is a portion of the cylindrical core 31 that is located on the side that is inserted into the insertion hole 21 of the vehicle body side fixing portion 20. The second extending portion 33 is a portion of the cylindrical core 31 that is located on the side that is supported by the bearing portion 18. The bending portion 34 is a portion that connects the first extending portion 32 and the second extending portion 33 of the cylindrical core 31.

[0031] <Edge> 5, 6, 7, and 8, the cylindrical core 31 has recesses 35. The recesses 35 are formed on the outer peripheral surface of the first extension portion 32. Two recesses 35 are provided on each of the outer peripheral surface of the first extension portion 32 at positions spaced 180 degrees apart in the circumferential direction of the first extension portion 32.

[0032] 5, each recess 35 has a rectangular shape in a plan view. Each recess 35 is formed on the outer circumferential surface of the first extension portion 32 with the longitudinal direction of the recess 35 coinciding with the axial direction of the first extension portion 32. Each recess 35 is formed by crushing a portion of the first extension portion 32.

[0033] Both edges 36 located in the longitudinal direction of each recess 35 extend in a direction perpendicular to the axis of the first extension portion 32. The edge 36 located on one side of the longitudinal direction of each recess 35 is located on a straight line extending in a direction perpendicular to the axis of the first extension portion 32 when each recess 35 is viewed in a plane. The edge 36 located on the other side of the longitudinal direction of each recess 35 is located on a straight line extending in a direction perpendicular to the axis of the first extension portion 32 when each recess 35 is viewed in a plane. In this way, each edge 36 extends in a direction intersecting with the axial direction of the first extension portion 32 of the cylindrical core 31. Both edges 36 located in the longitudinal direction of each recess 35 are formed by crushing a part of the first extension portion 32.

[0034] <Latching part> As shown in Figs. 3 and 9, the cylindrical core 31 has a locking portion 37. The locking portion 37 is provided at the end of the first extending portion 32 opposite to the bent portion 34. The locking portion 37 has a trumpet shape that increases in diameter toward the end of the first extending portion 32 opposite to the bent portion 34. The locking portion 37 is formed by flaring the end of the first extending portion 32 opposite to the bent portion 34. In this way, the locking portion 37 is provided at a portion of the cylindrical core 31 located on the opposite side to the sun visor body 11 with respect to the edge 36.

[0035] <Coating resin> As shown in FIG. 3 and FIG. 4, the coating resin 41 has a first resin portion 42, a second resin portion 43, and a third resin portion 44. The first resin portion 42 covers the outer peripheral surface of the first extending portion 32 of the cylindrical core 31. The second resin portion 43 covers the outer peripheral surface of the second extending portion 33 of the cylindrical core 31. The third resin portion 44 covers the outer peripheral surface of the bent portion 34 of the cylindrical core 31. The first resin portion 42 is cylindrical and extends along the outer peripheral surface of the first extending portion 32. The second resin portion 43 is cylindrical and extends along the outer peripheral surface of the second extending portion 33. The third resin portion 44 is cylindrical and extends along the outer peripheral surface of the bent portion 34. The third resin portion 44 is a portion that connects the first resin portion 42 and the second resin portion 43 in the coating resin 41.

[0036] As shown in FIG. 4, the first resin part 42 has a large diameter part 45, a small diameter part 46, and a locking head 47. The large diameter part 45 is continuous with the third resin part 44. The small diameter part 46 is continuous with an end part of the large diameter part 45 opposite the third resin part 44. The outer diameter of the small diameter part 46 is smaller than the outer diameter of the large diameter part 45. The locking head 47 is continuous with an end part of the small diameter part 46 opposite the large diameter part 45. The outer diameter of the locking head 47 is larger than the outer diameter of the small diameter part 46 and smaller than the outer diameter of the large diameter part 45.

[0037] 9, the end of the locking head 47 opposite the small diameter portion 46 covers the tip of the locking portion 37 of the cylindrical core 31. An opening hole 47h is formed in the end of the locking head 47 opposite the small diameter portion 46. The opening hole 47h communicates with the inside of the first extending portion 32 of the cylindrical core 31. The axis of the opening hole 47h coincides with the axis of the first extending portion 32.

[0038] The first resin part 42 has a locked part 48 with which the locking part 37 of the cylindrical core 31 is locked. The locked part 48 is formed on the inner surface of the locking head 47. The locked part 48 is an annular recess with which the locking part 37 is locked. The locking part 37 is locked to the locked part 48, thereby preventing the first extending part 32 from moving in the axial direction relative to the first resin part 42. Therefore, the locking part 37 is locked to the coating resin 41 and prevents the cylindrical core 31 from moving in the axial direction relative to the coating resin 41.

[0039] <Slit> As shown in Figs. 4, 6 and 7, slits 49 are formed in the coating resin 41. The slits 49 are formed in the large diameter portion 45 of the first resin part 42. The slits 49 are formed one by one at portions 180 degrees apart in the circumferential direction of the large diameter portion 45 of the first resin part 42. Each slit 49 has an elongated hole shape. Each slit 49 is formed in the large diameter portion 45 of the first resin part 42 with the longitudinal direction of each slit 49 extending in a direction perpendicular to the axial direction of the first resin part 42.

[0040] The slits 49 expose to the outside the edge 36 located farther from the bent portion 34, of both edges 36 located in the longitudinal direction of each recess 35. Therefore, of both edges 36 located in the longitudinal direction of each recess 35, the edge 36 located closer to the bent portion 34 is not exposed to the outside and is covered by the covering resin 41.

[0041] <Weakened Part> When a predetermined external force acts on the support shaft 30 and stress is applied to the cylindrical core 31, the cylindrical core 31 is easily broken starting from each edge 36 exposed to the outside from the slit 49. Therefore, of both edges 36 located in the longitudinal direction of each recess 35, the edge 36 exposed to the outside from the slit 49 is a weak portion 50. Therefore, the cylindrical core 31 has a weak portion 50. In this manner, the weak portion 50 in this embodiment is the edge 36 formed by crushing a part of the cylindrical core 31. The slit 49 exposes the weak portion 50 to the outside.

[0042] <Positional relationship between the fragile parts and slits and the cabin side surface> As shown in FIG. 2, the support shaft 30 is inserted into the insertion hole 21 until the locking head 47 climbs over each of the locking claws 22 and protrudes from an opening of the insertion hole 21 located on the opposite side to the vehicle interior surface 20a. When the locking head 47 passes through, each of the locking claws 22 elastically deforms in a direction away from the axis of the insertion hole 21. Then, when the locking head 47 climbs over each of the locking claws 22, each of the locking claws 22 returns to its original shape. As a result, the step surface 42e between the small diameter portion 46 and the locking head 47 in the first resin portion 42 is locked by each of the locking claws 22. In this manner, the first end of the support shaft 30 is supported by the vehicle body side fixing portion 20.

[0043] With the support shaft 30 supported by the vehicle body side fixed part 20, the weak part 50 and the slit 49 are located on the same plane as the vehicle interior side surface 20a. The weak part 50 and the slit 49 are located on an imaginary plane 51 that passes over the vehicle interior side surface 20a and crosses the opening of the insertion hole 21 on the vehicle interior side surface 20a side. Therefore, the support shaft 30 is inserted into the insertion hole 21 with the weak part 50 and the slit 49 located on the same plane as the vehicle interior side surface 20a.

[0044] [Operation of the embodiment] Next, the operation of this embodiment will be described. Incidentally, when a predetermined external force acts on the sun visor body 11, the external force acting on the sun visor body 11 may act on the support shaft 30. At this time, the fragile portion 50 is exposed to the outside through the slit 49. For this reason, compared to the case where the fragile portion 50 is covered by the coating resin 41, for example, when a predetermined external force acts on the support shaft 30 and the stress applied to the cylindrical core 31 is applied to the fragile portion 50, the cylindrical core 31 is more likely to break starting from the fragile portion 50. And, at the same time that the cylindrical core 31 breaks starting from the fragile portion 50, the coating resin 41 is also likely to break starting from the slit 49. And, depending on the predetermined external force acting on the support shaft 30, the cylindrical core 31 breaks starting from the fragile portion 50, and at the same time, the coating resin 41 also breaks starting from the slit 49. In this way, the cylindrical core 31 and the coating resin 41 are broken at the same time. Therefore, the fragile portion 50 becomes the starting point of the breakage of the cylindrical core 31.

[0045] 10, the broken portions of the core 31 and the coating resin 41 are located on the same plane as the vehicle interior side surface 20a of the vehicle body side fixing part 20. Therefore, the broken portions of the core 31 and the coating resin 41 are prevented from protruding from the vehicle interior side surface 20a of the vehicle body side fixing part 20. In addition, when the core 31 is broken starting from the fragile part 50, the locking part 37 prevents the core 31 from moving in the axial direction relative to the coating resin 41.

[0046] [Effects of the embodiment] The above embodiment can provide the following effects. (1) The fragile portion 50 is exposed to the outside through the slit 49. For this reason, for example, compared to a case where the fragile portion 50 is covered with the coating resin 41, when a predetermined external force acts on the support shaft 30 and a stress is applied to the cylindrical core 31, the cylindrical core 31 is more likely to break from the fragile portion 50 as a starting point. And, at the same time that the cylindrical core 31 is broken from the fragile portion 50 as a starting point, the coating resin 41 is also likely to break from the slit 49 as a starting point. Therefore, by simultaneously breaking the cylindrical core 31 and the coating resin 41, even if a predetermined external force acts on the sun visor body 11, it is possible to suppress the external force acting on the sun visor body 11 from being applied to the vehicle body side fixing part 20 through the support shaft 30.

[0047] (2) The support shaft 30 is inserted into the insertion hole 21 with the fragile portion 50 and the slit 49 positioned on the same plane as the vehicle interior side surface 20a. This allows the damaged portions of the cylindrical core 31 and the covering resin 41 to be positioned on the same plane as the vehicle interior side surface 20a of the vehicle body side fixing part 20. As a result, the damaged portions of the cylindrical core 31 and the covering resin 41 do not protrude into the vehicle cabin from the vehicle interior side surface 20a of the vehicle body side fixing part 20. This makes it easier to prevent the damaged portions of the cylindrical core 31 and the covering resin 41 from protruding from the vehicle interior side surface 20a of the vehicle body side fixing part 20.

[0048] (3) The edge 36 formed by crushing a part of the cylindrical core 31 so as to extend in a direction intersecting the axial direction of the cylindrical core 31 is suitable as the weak part 50. Moreover, since the weak part 50 can be formed in the cylindrical core 31 simply by crushing a part of the cylindrical core 31, the configuration of the cylindrical core 31 can be simplified.

[0049] (4) A locking portion 37 that is locked to the coating resin 41 and prevents the axial movement of the core 31 relative to the coating resin 41 is provided in a portion of the core 31 that is located on the opposite side to the sun visor body 11 from the fragile portion 50. With this, for example, when the core 31 breaks starting from the fragile portion 50, the locking portion 37 can prevent the core 31 from moving in the axial direction relative to the coating resin 41. As a result, for example, when the core 31 breaks starting from the fragile portion 50, it is possible to prevent the broken portion of the core 31 from protruding farther into the vehicle cabin than the broken portion of the coating resin 41.

[0050] (5) Even if a predetermined external force acts on the sun visor body 11, the external force acting on the sun visor body 11 can be prevented from being applied to the vehicle body side fixing part 20 via the support shaft 30. As a result, it becomes easier to avoid problems such as the vehicle body side fixing part 20 breaking and the broken part of the vehicle body side fixing part 20 being exposed inside the vehicle cabin or the broken part of the vehicle body side fixing part 20 being scattered inside the vehicle cabin.

[0051] (6) Depending on a predetermined external force acting on the support shaft 30, the cylindrical core 31 breaks starting from the fragile portion 50, and at the same time, the coating resin 41 also breaks starting from the slit 49. Therefore, since the sun visor body 11 and the vehicle body side fixing part 20 can be separated, even if a predetermined external force acts on the sun visor body 11, it is possible to prevent the external force acting on the sun visor body 11 from being applied to the vehicle body side fixing part 20 via the support shaft 30.

[0052] [Example of change] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0053] As shown in Figs. 11 and 12, the support shaft 30 may be inserted into the insertion hole 21 with the weak portion 50 and the slit 49 disposed at a position where they are inserted inside the insertion hole 21 with respect to the vehicle interior side surface 20a. As shown in Fig. 11, the weak portion 50 and the slit 49 are disposed at a position where they are inserted inside the insertion hole 21 with respect to the vehicle interior side surface 20a and an imaginary plane 51 that passes over the vehicle interior side surface 20a and crosses the opening of the insertion hole 21 on the vehicle interior side surface 20a side. According to this, as shown in Fig. 12, the portion where the cylindrical core 31 and the coating resin 41 are broken can be located at a position where they are inserted inside the insertion hole 21 with respect to the vehicle interior side surface 20a of the vehicle body side fixing part 20. As a result, the portion where the cylindrical core 31 and the coating resin 41 are broken does not protrude from the vehicle interior side surface 20a of the vehicle body side fixing part 20 into the vehicle interior. Therefore, it is possible to easily prevent the broken portions of the cylindrical core 31 and the coating resin 41 from protruding from the vehicle interior side surface 20a of the vehicle body side fixing part 20.

[0054] In the embodiment, when the cylindrical core 31 breaks starting from the fragile portion 50, the covering resin 41 also breaks starting from the slit 49, but this is not limiting, and the cylindrical core 31 and the covering resin 41 do not have to break. Even if the cylindrical core 31 breaks starting from the fragile portion 50, the covering resin 41 does not have to break. In short, when a predetermined external force acts on the support shaft 30 and the stress applied to the cylindrical core 31 is applied to the fragile portion 50, it is sufficient that the cylindrical core 31 at least breaks starting from the fragile portion 50. And, it is sufficient that the covering resin 41 also breaks at least starting from the slit 49 at the same time that the cylindrical core 31 breaks starting from the fragile portion 50.

[0055] In the embodiment, the edge 36 extends in a direction perpendicular to the axis of the first extension portion 32, but this is not limiting, and for example, the edge 36 may extend obliquely to the axis of the first extension portion 32. In short, it is sufficient that the edge 36 extends in a direction intersecting the axial direction of the first extension portion 32 of the cylindrical core 31.

[0056] In the embodiment, the support shaft 30 may be configured such that the slit 49 exposes to the outside the edge 36 located closer to the bent portion 34, of both edges 36 located in the longitudinal direction of each recess 35. In this case, of both edges 36 located in the longitudinal direction of each recess 35, the edge 36 located closer to the bent portion 34 functions as the weakened portion 50.

[0057] In the embodiment, the fragile portion 50 is not limited to the edge 36 formed by crushing a part of the cylindrical core 31 so as to extend in a direction intersecting the axial direction of the cylindrical core 31. The fragile portion 50 may be, for example, an edge of a through hole formed in a part of the cylindrical core 31, or an edge formed by making a cut in a part of the cylindrical core 31. In short, the configuration of the fragile portion 50 is not particularly limited.

[0058] In the embodiment, the cylindrical core 31 does not necessarily have to be provided with the locking portion 37 . In the embodiment, only one recess 35 may be provided on the outer circumferential surface of the first extension portion 32. In short, the number of edges 36 formed on the cylindrical core 31 is not particularly limited. The number of slits 49 may also be appropriately changed according to the number of edges 36.

[0059] In the embodiment, the vehicle compartment side surface 20a of the vehicle body side fixing part 20 may be, for example, a flat surface. In the embodiment, the outer diameter of the locking head 47 is larger than the outer diameter of the small diameter portion 46 and smaller than the outer diameter of the large diameter portion 45, but this is not limited to this. In short, the shape of the portion of the first end of the spindle 30 that is supported by the vehicle body side fixed portion 20 is not particularly limited. In other words, the first resin part 42 is not limited to a configuration having the large diameter portion 45, the small diameter portion 46, and the locking head 47.

[0060] In the embodiment, the vehicle body side fixing part 20 does not have to have the locking claw 22. In this case, for example, a locking member may be separately provided at an opening of the insertion hole 21 located on the opposite side to the vehicle interior side surface 20a, and the first end of the support shaft 30 may be locked to the locking member, thereby supporting the support shaft 30 on the vehicle body side fixing part 20.

[0061] In the embodiment, the sun visor body 11 may be solid. In other words, the sun visor body 11 is not limited to being hollow. In the embodiment, the shape of the sun visor body 11 may be changed as appropriate.

[0062] In the embodiment, the material of the sun visor body 11 can be changed as appropriate. [Explanation of symbols]
