[0001] The present invention relates to a sun visor provided in a vehicle, and the sun visor body is a slide-type vehicle sun visor that can move in the longitudinal axis direction of the support shaft.

[0002] The vehicle sun visors disclosed in Patent Documents 1 and 2 have a plate-shaped visor body and a support shaft that rotatably supports the visor body. The visor body rotates about the support shaft to rotate between a use position along the front glass and a storage position along the ceiling. A slide mechanism for sliding the visor body along the support shaft is provided inside the visor body. The visor body can be slid with respect to the support shaft in the longitudinal direction of the visor body by using the slide mechanism. The visor body disclosed in Patent Document 1 has a front shell and a back shell. A bearing portion is slidably attached to a slide rail provided inside the visor body. An end portion of the support shaft is attached to the bearing portion. The slide rail is held by being screwed to the back shell.

[0003] The visor body disclosed in Patent Document 2 is composed of two split bodies. A support is slidably attached to a guide rail formed inside the visor body. An end portion of the support shaft is attached to the support. The guide rail protrudes from the inner walls of the two split bodies toward the other split body, and each guide rail extends in the extending direction of the support shaft. An engaging piece, which is a spring piece, is formed on the side wall of the support. When the support moves along the guide rail, the engaging piece moves while abutting against the guide rail, so that the posture of the support with respect to the visor body is maintained.

[0004] Japanese Unexamined Patent Application Publication No. 2013 - 252739, Japanese Unexamined Patent Application Publication No. 2010 - 173385

[0005] According to Patent Document 1, the slide rail and the back shell are screwed to the front shell. That is, the visor body includes a separately provided slide rail, and the slide rail is screwed. Therefore, the number of parts is large and the assembly work takes time, so the manufacturing cost may increase.

[0006] According to Patent Document 2, the support needs to be assembled in a fixed position and orientation between two divided parts. However, when the divided parts are molded, for example, the heat generated during molding can cause thermal deformation, resulting in variations in shape between the divided parts. In such cases, assembly of the support and other components is not easy. Therefore, there is a need for a sliding mechanism for a sun visor that has fewer parts and assembly steps, and is easy to assemble.

[0007] According to one feature of this disclosure, a vehicle sun visor has a visor body comprising a first component and a second component stacked in the thickness direction. A support shaft is inserted into the visor body, and the support shaft rotatably supports the visor body between an operational position and a retracted position. Inside the visor body is provided a case that rotatably supports the support shaft and is slidably mounted relative to the visor body. The case is provided with a clip that biases the visor body to the retracted position by biasing the support shaft. A guide rail is provided to prevent the case from falling off relative to the first component in the thickness direction. The guide rail is integrally formed with the first component so as to slidably support the case relative to the first component.

[0008] Therefore, the case is supported by the visor body only by guide rails integrally formed with the first component. As a result, separate rails are unnecessary, and the process of screwing rails to the visor body is also unnecessary. Thus, the sun visor can be manufactured at a low cost. The guide rails prevent the case from falling off the first component in the thickness direction. As a result, the case is held in a constant position by the first component alone. Therefore, it can be held in a more stable position compared to a case held between the first and second components. For example, it is possible to avoid the case's position being affected by assembly errors between the first and second components or variations in the size of each part. Moreover, by making the second component have a simple structure and concentrating the function and structure in the first component, the rigidity of the first component is increased, and the structure of the visor body can be simplified. As a result, the manufacturing cost of the sun visor can be reduced.

[0009] According to one feature of this disclosure, the guide rail has a first rail and a second rail. The first rail slidably supports a first end edge of the case. The second rail slidably supports a second end edge of the case located opposite the first end edge. The first rail and the second rail are integrally formed with a first component. Therefore, since both the upper and lower ends of the case in the sliding direction are supported by the first component, the sliding load is stably held by the first component.

[0010] According to one feature of this disclosure, the case has a first end edge that engages with a guide rail. The guide rail has at least one notch into which the first end edge can be inserted in the thickness direction of the first component. The guide rail has a guide rail body that is elongated in the sliding direction. The first end edge of the case is engageable with the guide rail body in such a way that it slides and cannot fall out in the thickness direction of the visor body. Therefore, the case is attached to the guide rail by inserting the first end edge into the notch of the guide rail. Thus, the case can be easily attached to the guide rail without deforming the guide rail.

[0011] According to one feature of this disclosure, the second component, when attached to the first component, has a stopper that protrudes from the second component toward the end of the guide rail of the first component and prevents the first edge from coming out of the notch of the guide rail. Therefore, when assembling the case to the guide rail, first insert the first edge of the case into the notch. Slide the case against the guide rail to separate the first edge from the notch. In this state, attach the second component to the first component. The stopper of the second component prevents the first edge of the case from coming out of the notch of the guide rail. Therefore, after assembling the case to the guide rail, it is prevented from falling off the guide rail.

[0012] According to one feature of the present disclosure, the first edge portion has a first engaging portion and a second engaging portion on a straight line parallel to the sliding direction of the case. The first engaging portion is formed at or near the first end of the case in the sliding direction and has a first width in the sliding direction. The second engaging portion is formed at or near the second end, which is the other end of the first end, and has a second width that is narrower than the first width in the sliding direction. The notch portion of the guide rail has a first notch portion and a second notch portion. The first notch portion has a width in the sliding direction that is wider than the first width and into which the first engaging portion can be inserted in the thickness direction. The second notch portion has a width in the sliding direction that is narrower than the first width and wider than the second width and into which the second engaging portion can be inserted in the thickness direction.

[0013] Therefore, the case can be attached to the guide rail at a mounting position where the first engaging portion can be inserted through the first notch and the second engaging portion can be inserted through the second notch. The first engaging portion is wider than the second notch and therefore does not come off the second notch. Thus, even when the case moves away from the mounting position and the first engaging portion reaches the second notch, it does not come off the guide rail. In addition, the assembly direction of the case is visually determined from the two notches of different widths, so the case is not assembled in the wrong direction.

[0014] According to one feature of the present disclosure, the first notch is formed at the end of the sliding region of the guide rail on which the case slides, in the first sliding direction. A first engagement portion is formed at or near the first end of the case in the first sliding direction. The second component, when attached to the first component, has a stopper that protrudes from the second component toward the end of the guide rail of the first component and restricts the first end edge from coming out of the notch of the guide rail.

[0015] Therefore, when attaching the case to the guide rail, the case is positioned in the recess or protrusion provided on the second rail, which slidably supports the protrusion or recess on the second edge of the case, and is then inserted into the first and second notches of the first rail, which slidably support the first and second engaging portions formed on the first edge of the case. The case is slid relative to the guide rail so that the first engaging portion moves away from the first notch. In this state, the second component is attached to the first component. This prevents the first engaging portion from returning to the position of the first notch by the stopper. Thus, it is possible to prevent the first edge of the case from falling out of the notch after the second component is assembled to the first component.

This is an exploded front view of the sliding structure of the sun visor. This is an exploded front view of the clip, case, and a part of the guide rail of the visor body. This is a perspective view of the clip as seen from the back. This is a front view of the first component of the sun visor and the case and clip inserted into the guide rail. This is a cross-sectional view taken along the line VII-VII in Figure 6. This is an enlarged front view of the case slid to the right from the position in Figure 6. This is a cross-sectional view taken along the line IX-IX in Figure 8. This is an exploded view of the vehicle sun visor showing the embodiment of Figure 9. This is a partially enlarged cross-sectional view of the sun visor in the assembled state.

[0017] One embodiment of the present invention will be described with reference to Figures 1 and 2. As shown in Figure 1, the vehicle sun visor 1 is mounted on the ceiling surface 20 near the windshield 21 inside the vehicle. The vehicle sun visor 1 comprises a visor body 1a and a mirror unit 12 provided on one side of the visor body 1a. A support shaft 7 that rotatably supports the visor body 1a is attached to the visor body 1a via a clip 6 assembled to the case 5. The visor body 1a rotatably supports the support shaft 7. The case 5 is slidably mounted on the vehicle sun visor body 1a.

[0018] As shown in Figures 1 to 7, the visor body 1a has a roughly rectangular shape and comprises a first component 2 and a second component 3, which are flat plates stacked in the thickness direction. A skin 13 is placed over the surface of the visor body 1a. The support shaft 7 is a roughly L-shaped rod, with the vertical shaft 7a extending upward from the tip of the horizontal shaft 7b, substantially perpendicular to the horizontal shaft 7b. A bracket 11 is attached to the tip of the vertical shaft 7a, and the bracket 11 is attached to the ceiling surface 20 of the vehicle interior. The horizontal shaft 7b is inserted from the side of the visor body 1a along the upper edge of the visor body 1a. A slotted surface 7h provided on the small diameter portion 7d of the support shaft is inserted through the opening 5f of the case 5 and the opening 6a of the clip 6, and assembled to the clip pressing portion 6b.

[0019] As shown in Figures 1 and 2, the shaft 9 is substantially cylindrical and is detachably held by a hook 10 fixed to the ceiling surface 20. When the shaft 9 is attached to the hook 10, the visor body 1a rotates between a usage position P along the windshield 21 and a storage position K along the ceiling surface 20, with the shaft 9 and the horizontal axis 7b as the axis. By removing the shaft 9 from the hook 10, the visor body 1a becomes rotatable around the vertical axis 7a. This allows the visor body 1a to rotate between a usage position P along the windshield 21 and a side position S along the side window 22.

[0020] As shown in Figures 2 and 3, a guide rail 4 is provided on the inner surface 2b of the first component 2 to slide the visor body 1a along the horizontal axis 7b, thereby supporting the case 5 in a slidable manner. The guide rail 4 is substantially rectangular in shape. As shown in Figures 3 and 4, the guide rail 4 has a first rail 4a that protrudes downward from the upper edge 4p of the visor of the first component 2. The guide rail 4 has a plate-shaped base 4q at a position corresponding to the bottom of the rectangle. The base 4q protrudes substantially vertically from the inner surface 2b of the first component 2. As shown in Figures 4 and 9, a second rail 4b is formed protruding from the upper surface 4r of the base 4q, extending parallel to the first rail 4a. The case 5 is slidably supported by the first rail 4a and the second rail 4b.

[0021] As shown in Figures 4, 7, and 9, the second rail 4b protrudes from the base 4q toward the first rail 4a. The region 4m between the upper edge 4p of the visor and the base 4q is elongated in the longitudinal direction of the visor body 1a and allows the case 5 to slide in the left-right direction. The region 4m is provided with a protruding ridge 4n that protrudes from the upper edge 4p of the visor and extends in the longitudinal direction, and a plurality of vertical reinforcing portions 4h. At the connection portion between the first component 2 and the base 4q, a slide support portion 4i is formed that protrudes inward from the first component 2. The slide support portion 4i extends in the left-right direction parallel to the second rail 4b or the base 4q.

[0022] As shown in Figures 4 and 7, the protruding portion 4n is located on the back side of the first end edge (first engaging portion 5g and second engaging portion 5h) of the case 5 and extends parallel to the first rail 4a. As shown in Figure 9, the protruding portion 4n cooperates with the first rail 4a to slidably support the first end edge. Specifically, the protruding portion 4n supports the back surface 5z of the first end edge, and the first rail 4a supports the front surface 5y of the first end edge.

[0023] The small-diameter portion 7d of the horizontal shaft 7b shown in Figure 3 is held via a clip 6 attached to a case 5 provided on the guide rail 4 (see Figure 10). The horizontal shaft 7b is slidably supported by an inlet receiving portion 4f formed at the right end position of the guide rail 4. The inlet receiving portion 4f has an opening 4g into which the large-diameter portion 7c of the horizontal shaft 7b can be inserted. Thus, the horizontal shaft 7b is held via the inlet receiving portion 4f provided on the first component 2 and the clip 6 attached to the case 5.

[0024] As shown in Figures 3 and 11, a back wall portion 4k is provided at the left end of the guide rail 4. The back wall portion 4k has an opening 4l with a diameter smaller than the small diameter portion 7d of the horizontal axis 7b. Multiple terminals 2a are provided at the left side of the back wall portion 4k. For example, two terminals 2a are arranged side by side in the horizontal direction at a position above the horizontal axis 7b. Two other terminals 2a are arranged side by side in the horizontal direction at a position below the horizontal axis 7b. As shown in Figure 10, the tip portion 7e of the support shaft 7 is inserted into the position where the terminals 2a are provided, and in this state, when the visor body 1a is in the usage position P, the terminal portions 7f and 7g of the support shaft 7 come into contact with the terminals 2a of the visor body 1a. When the visor body 1a is in the storage position K, the terminal portions 7f and 7g move away from the terminals 2a.

[0025] As shown in Figures 4 and 5, the clip 6 is formed by bending a single-piece leaf spring and grips the small-diameter portion 7d of the support shaft 7 at three points in the circumferential direction. The clip biases and holds the rotation of the visor body 1a between the usage position P along the windshield 21 and the storage position K along the ceiling surface 20, with the small-diameter portion 7d as the center. After the clip 6 is fitted into the case 5, the small-diameter portion 7d of the support shaft is inserted into the clip 6 and assembled.

[0026] As shown in Figures 3 and 4, the case 5 houses the clip 6. The case 5 is slidable relative to the guide rail 4. The case 5 has a left vertical wall portion 5a and a right vertical wall portion 5b, and a clip holding portion 5c that connects the two vertical wall portions 5a and 5b at the bottom. The case 5 is made of, for example, resin. The two vertical wall portions 5a and 5b are spaced apart in the longitudinal direction of the first component member 2. The width of the vertical wall portion 5a in the sliding direction is greater than the width of the vertical wall portion 5b in the sliding direction.

[0027] As shown in Figures 4 and 7, the heads of the vertical wall portions 5a and 5b provided at both the left and right ends of the case 5 are substantially cylindrical. As shown in Figure 4, the heads of the vertical wall portions 5a and 5b are provided with first and second engaging portions 5g and 5h that protrude upward. The tip surfaces 5v of the first and second engaging portions 5g and 5h are tapered along the inner surface 2b of the first component member 2. The vertical wall portions 5a and 5b are formed with openings 5e and 5f having an inner circumferential surface 5m with a substantially circular cross-section.

[0028] As shown in Figures 4 and 8, an elastic piece 5d is formed on the bottom surface 5q of the case 5, which elastically contacts the upper surface 4r of the base 4q to provide frictional resistance. The elastic piece 5d is made of, for example, resin. The elastic piece 5d has an arc shape when viewed from the front. Bottom protrusions 5j are formed on both the left and right ends of the bottom surface 5q.

[0029] As shown in Figures 4 and 6, the first rail 4a is provided with a rear notch 4c and an entrance notch 4d so that the case 5 can be assembled to the guide rail 4. The rear notch 4c is located at the left end of the guide rail 4 and is situated between the left end of the first rail 4a and the rear wall 4k. The rear notch 4c is wider than the first engaging portion 5g formed on the first end edge of the case 5, allowing the first engaging portion 5g to be inserted into the guide rail 4.

[0030] As shown in Figure 4, the entrance-side notch 4d is located to the right of the rear-side notch 4c, with a gap between them. The entrance-side notch 4d is wider than the second engaging portion 5h formed on the first end edge of the vertical wall portion 5b of the case 5, allowing the second engaging portion 5h to be inserted into the guide rail 4. The entrance-side notch 4d is narrower than the first engaging portion 5g of the case 5. Therefore, when the first engaging portion 5g is positioned in the entrance-side notch 4d, it is prevented from coming out of the entrance-side notch 4d.

[0031] As shown in Figure 4, a stopper housing area 4e is formed at the left end of the guide rail 4. The stopper housing area 4e is located below the rear notch 4c and accommodates the stopper 8 (see Figure 10) of the second component 3 when the first component 2 and the second component 3 are stacked in the thickness direction. As shown in Figure 10, the stopper 8 is provided on the second component 3 to restrict the movement of the case 5 to the left of the guide rail 4. The stopper 8 is, for example, rectangular prism-shaped and protrudes from the inner surface 3b of the second component 3. As shown in Figures 4 and 10, a fall prevention projection 4j is provided on the upper surface 4r of the base 4q, extending parallel to the second rail 4b from a position near the left end 4s of the second rail 4b. Note that, as shown in Figure 8, multiple fall prevention projections 4j may be provided on the upper surface 4r. As shown in Figures 8 and 9, the anti-detachment projection 4j contacts the horizontal overhang 5n when the case 5 is assembled to the guide rail 4, preventing the case 5 from falling off the guide rail 4.

[0032] To attach case 5 to guide rail 4, first, as shown in Figures 4, 6, and 10, the lower part (second end edge) of case 5 is engaged with the second rail 4b of guide rail 4. Specifically, the elastic piece 5d of case 5, the lower rail protrusion 5i, and each bottom surface protrusion 5j are placed so that they pass over the anti-detachment projection 4j and come into contact with the upper surface 4r of base 4q. Next, the upper part (first end edge) of case 5 is engaged with the first rail 4a of guide rail 4. Specifically, as shown in Figures 7 and 8, the first engaging part 5g formed on the first end edge of the vertical wall portion 5a of case 5 is inserted into the rear notch 4c. At the same time, the second engaging part 5h formed on the first end edge is inserted into the entrance side notch 4d. Then, the first engaging part 5g and the second engaging part 5h of case 5 are brought into contact with the protruding portion 4n. Thus, case 5 is attached to guide rail 4.

[0033] Next, as shown in Figures 4 and 8, the case 5 is attached to the guide rail 4 and then slid to the right. As a result, as shown in Figure 8, the first engaging portion 5g of the case 5 separates from the rear notch 4c of the guide rail 4. Furthermore, as shown in Figure 10, the first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the case 5 are held between the first rail 4a and the protruding portion 4n. The second rail 4b is then held between the elastic piece 5d of the case 5 and the lower rail protrusion 5i. Thus, the case 5 is attached to the guide rail 4 without elastic deformation.

[0034] As shown in Figures 8 and 9, the front surface 5x of the bottom protrusion 5j at one end or both ends of the case 5 abuts against the fall prevention projection 4j. This allows the case 5 to cooperate with the second rail 4b to hold the case 5 more firmly. The back surface protrusion 5p of the case 5 abuts against the slide support part 4i. Therefore, when the visor body 1a rotates between the usage position P and the storage position K, the back surface protrusion 5p restricts the case 5 from moving in the thickness direction relative to the second rail 4b.

[0035] Next, as shown in Figures 3 and 10, the horizontal shaft 7b is inserted through the opening 4g of the entrance receiving portion 4f along the guide rail 4. The horizontal shaft 7b passes through the openings 5e and 5f of the case 5 (see Figure 4), the opening 6a of the clip 6, and the opening 4l of the back wall portion 4k. Finally, as shown in Figure 11, the second component 3 is attached to the first component 2 by overlapping it in the thickness direction. The first component 2 and the second component 3 are connected to each other, for example, by connecting pins.

[0036] At this time, the stopper 8 provided on the inner surface 3b of the second component 3 comes into contact with the stopper housing area 4e of the first component 2. This prevents the vertical wall portion 5a of the case 5 from reaching the rear notch portion 4c. Also, as shown in Figures 10 and 11, the inner surface 3b is provided with a protruding ridge portion 3c that projects toward the case 5. The protruding ridge portion 3c can restrict the movement of the case 5 in the thickness direction and the vertical direction. Thus, after assembling the second component 3 to the first component 2, it is possible to prevent the case 5 from falling out of the rear notch portion 4c and the entrance side notch portion 4d.

[0037] As described above, as shown in Figures 1, 2, and 10, the vehicle sun visor 1 has a visor body 1a comprising a first component 2 and a second component 3 stacked in the thickness direction. A support shaft 7 is inserted into the visor body 1a, and the support shaft 7 supports the visor body 1a so that it can rotate between a usage position P and a storage position K. As shown in Figures 3 and 7, a case 5 is provided inside the visor body 1a that rotatably supports the support shaft 7 and is slidably mounted on the visor body 1a. The case 5 is provided with a clip 6 that biases the visor body 1a to the storage position K by biasing the support shaft 7. A guide rail 4 is provided to prevent the case 5 from falling off the first component 2 in the thickness direction. The guide rail 4 is integrally formed with the first component 2 so as to support the case 5 so that it can slide relative to the first component 2.

[0038] Therefore, case 5 is supported by the visor body 1a only by the guide rail 4 which is integrally formed with the first component 2. As a result, a separate rail or the like is unnecessary, and the process of screwing the rail or the like to the visor body 1a is also unnecessary. Thus, the sun visor 1 can be manufactured at low cost. The guide rail 4 prevents case 5 from falling off the first component 2 in the thickness direction. As a result, case 5 is held in a constant position by the first component 2 alone. Therefore, it can be held in a more stable position compared to case 5 held between the first component 2 and the second component 3. For example, it is possible to avoid the position of case 5 being affected by assembly errors between the first component 2 and the second component 3 or variations in the size of each part. Moreover, by making the second component 3 have a simple structure and concentrating the function and structure in the first component 2, the rigidity of the first component 2 is increased, and the structure of the visor body 1a can be simplified. As a result, the manufacturing cost of the sun visor 1 can be reduced.

[0039] As shown in Figures 3 and 4, the guide rail 4 has a first rail 4a and a second rail 4b. The first rail 4a slidably supports the first engagement portion 5g and the second engagement portion 5h formed on the first end edge of the case 5. The second rail 4b slidably supports the second end edges (5i, 5k, 5j) located on the opposite side of the first end edge of the case 5. The first rail 4a and the second rail 4b are integrally formed with the first component 2. Therefore, since both the upper and lower ends of the case 5 in the sliding direction are supported by the first component 2, the sliding load is stably held by the first component 2.

[0040] As shown in Figures 4 and 10, the case 5 has a first engaging portion 5g and a second engaging portion 5h formed on the first end edge that engages with the guide rail 4, and a second end edge. The guide rail 4 has a guide rail body (4a, 4b) that is long in the sliding direction. The first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the case 5 can engage with the guide rail body in such a way that they can slide and cannot fall out in the thickness direction of the visor body 1a. Furthermore, the guide rail 4 has notches (4c, 4d) formed on the first end edge that allow the first engaging portion 5g and the second engaging portion 5h formed on the first end edge to be inserted in the thickness direction of the visor body 1a.

[0041] Therefore, case 5 is attached to the guide rail 4 by inserting the first engaging portion 5g and the second engaging portion 5h, which are formed on the first end edge, through the notches (4c, 4d) of the guide rail 4. As a result, case 5 can be easily attached to the guide rail 4 without deforming the guide rail 4.

[0042] As shown in Figures 10 and 11, the second component 3 has a stopper 8 that prevents the first engaging portion 5g and the second engaging portion 5h formed on the first edge of the second component 3 from reaching the notches (4c, 4d) of the guide rail 4 when it is attached to the first component 2. Therefore, when assembling the case 5 to the guide rail 4, first insert the first engaging portion 5g and the second engaging portion 5h formed on the first edge of the case 5 into the notches (4c, 4d). Slide the case 5 against the guide rail 4 to separate the first engaging portion 5g and the second engaging portion 5h formed on the first edge from the notches (4c, 4d). In this state, attach the second component 3 to the first component 2. The stopper 8 of the second component 3 prevents the first engaging portion 5g and the second engaging portion 5h formed on the first edge of the guide rail 4 from reaching the notches (4c, 4d). Therefore, the case 5 is prevented from falling off the guide rail 4 after it has been assembled to the guide rail 4.

[0043] As shown in Figure 4, the first edge portion has a first engaging portion 5g and a second engaging portion 5h on a straight line parallel to the sliding direction of the case 5. The first engaging portion 5g is formed at or near the first end of the case 5 in the sliding direction and has a first width in the sliding direction. The second engaging portion 5h is formed at or near the second end, which is the other end of the first end, and has a second width that is narrower than the first width in the sliding direction. The notch portion of the guide rail 4 has a first notch portion 4c and a second notch portion 4d. The first notch portion 4c has a width in the sliding direction that is wider than the first width and allows the first engaging portion 5g to be inserted in the thickness direction. The second notch portion 4d has a width in the sliding direction that is narrower than the first width and wider than the second width and allows the second engaging portion 5h to be inserted in the thickness direction.

[0044] Therefore, the case 5 can be attached to the guide rail 4 at an attachment position where the first engaging portion 5g can be inserted through the first notch portion 4c and the second engaging portion 5h can be inserted through the second notch portion 4d. Since the width of the first engaging portion 5g is wider than that of the second notch portion 4d, the first engaging portion 5g cannot come out of the second notch portion 4d. Therefore, even if the case 5 moves away from the attachment position and the first engaging portion 5g reaches the second notch portion 4d, the case 5 does not come off the guide rail 4. Also, since the assembling direction of the case 5 can be visually recognized from the two notch portions with different widths, the case 5 cannot be assembled in the reverse direction.

[0045] As shown in FIGS. 4 and 10, the first notch portion 4c is formed at an end portion in the first sliding direction of the sliding region 4m of the guide rail 4 along which the case 5 slides. A first engaging portion 5g is formed at or near the first end portion of the case 5 in the first sliding direction. The second component 3 has a stopper 8 that protrudes from the second component 3 toward the end portion of the guide rail 4 of the first component 2 in a state where the second component 3 is attached to the first component 2, and restricts the first edge portion from coming out of the notch portions (4c, 4d) of the guide rail 4. The stopper 8 has, for example, a quadrangular prism shape.

[0046] Therefore, when attaching the case 5 to the guide rail 4, the convex portion or concave portion of the second edge portion of the case is arranged in the concave portion or convex portion provided on the second rail 4b, and further, the first engaging portion 5g and the second engaging portion 5h formed on the first edge portion of the case are inserted into the first notch portion 4c and the second notch portion 4d of the first rail 4a. The case 5 is slid with respect to the guide rail 4 so that the first engaging portion 5g moves to a position away from the first notch portion 4c. In this state, the second component 3 is attached to the first component 2. Thereby, the stopper 8 can prevent the first engaging portion 5g from returning to the position of the first notch portion 4c. Thus, it is possible to prevent the first edge portion of the case 5 from falling off from the notch portions (4c, 4d) of the guide rail 4 after the second component 3 is assembled to the first component 2.

[0047] The present disclosure is not limited to the appearance and configuration described in the above-described embodiments, and various modifications, additions, and deletions are possible without changing the gist. For example, as shown in FIGS. 4 and 7, the first and second engaging portions 5g and 5h of the case 5 are formed in a convex shape. The convex first and second engaging portions 5g and 5h are held by the cooperation of the protrusion 4n and the first rail 4a. Instead of this, the first engaging portion 5g of the case 5 may be a concave portion. Specifically, for example, the first engaging portion 5g of the case 5 may be a concave portion, and a convex portion that fits into the concave portion may be formed on the side of the first rail 4a.

[0048] As shown in FIGS. 4, 6, and 9, the case 5 is attached to the guide rail 4 by inserting the first engaging portion 5g and the second engaging portion 5h formed from the notch portions (4c, 4d) of the guide rail 4 to the first edge portion. For example, in addition to the notch portions (4c, 4d) of the first rail 4a, notch portions may be provided on the second rail 4b. At this time, the first engaging portion 5g and the second engaging portion 5h are inserted into the notch portions (4c, 4d) of the first rail, and the third engaging portion formed on the second edge portion opposite to the first edge portion is inserted into the notch portion of the second rail 4b, whereby the case 5 may be attached to the guide rail 4. Further, the widths of the notch portions (4c, 4d) of the first rail and the notch portions of the second rail 4b may be notch portions having different widths.

[0049] As shown in FIGS. 4, 8, and 9, the concave portion 5k of the case 5 is attached to the convex second rail 4b so as to fit. Instead of this, for example, the second rail 4b may be formed in a mountain shape or a trapezoidal shape, and the case 5 may be attached with the corresponding concave portion 5k of the case 5 having a corresponding shape.

[0050] As shown in FIGS. 4 and 7, the case 5 has the first engaging portion 5g and the second engaging portion 5h at the heads of the vertical wall portions 5a and 5b, respectively, and has a lower rail convex portion 5i, a bottom surface convex portion 5j, and an elastic piece 5d on the bottom surface. Instead of this, for example, the first rail 4a may be provided on the upper surface 4r of the base portion 4q, the second rail 4b may be provided on the upper edge of the visor, and the case 5 may be used upside down. At this time, the tip surface 5v of the first engaging portion 5g and the tip surface 5w of the second engaging portion 5h may be formed parallel to the upper surface 4r.

[0051] The first component 2 and the second component 3 may, for example, both cores may be molded from a hard resin, or the second component 3 may be formed from foamed resin. As shown in Figure 10, the first component 2 and the second component 3 are separate parts. Alternatively, for example, the first component 2 and the second component 3 may be integrally formed by connecting them via a hinge made of resin. In this case, the guide rail 4 may be provided on either the first component 2 side or the second component 3 side.

[0052] As shown in Figure 10, the stopper 8 is provided on the second component 3. Alternatively, the stopper 8 may be a separate component. The shape of the stopper 8 may be formed to match the shape and size of the stopper housing area 4e, instead of, for example, a rectangular prism shape.

[0053] As shown in Figures 3, 4, and 11, instead of the stopper 8, an opening 4l with a smaller diameter than the tip 7e of the horizontal shaft 7b may be formed in the back wall portion 4k, so that the tip 7e of the horizontal shaft 7b is not inserted into the opening 4l and is stopped at the opening 4l, thus functioning as a stopper 8.
