Description

Technical Field

[0001] The present invention relates to a sliding vehicle sun visor installed on a vehicle, wherein a sun visor main body is movable in the longitudinal direction of a support shaft. Background Art

[0002] The vehicle sun visor disclosed in Patent Documents 1 and 2 comprises a plate-shaped sun visor body and a support shaft that rotatably supports the sun visor body. The sun visor body rotates about the support shaft, thereby rotating between a use position along the front windshield and a storage position along the ceiling. A sliding mechanism is provided in the sun visor body, which is used to enable the sun visor body to slide along the support shaft. The sun visor body is able to slide relative to the support shaft in the longitudinal direction of the sun visor body by utilizing the sliding mechanism. The sun visor body disclosed in Patent Document 1 comprises a front shell and an inner shell. A bearing portion is slidably mounted on a sliding rail provided in the sun visor body. The end of the support shaft is mounted on the bearing portion. The sliding is maintained by being fixed to the inner shell by screws.

[0003] The sunshade body disclosed in Patent Document 2 is composed of two separate parts. A support member is slidably mounted on a guide rail formed in the sunshade body. The end of the support shaft is mounted on the support member. The guide rail protrudes from the inner wall of the two separate parts toward the other separate part, and each guide rail extends in the direction in which the support shaft extends. A snap-fitting piece serving as a spring piece is formed on the side wall of the support member. When the support member moves along the guide rail, the snap-fitting piece moves while contacting the guide rail, thereby maintaining the posture of the support member relative to the sunshade body.

[0007] Patent Document 2: Japanese Patent Application Laid-Open No. 2010-173385 Summary of the Invention

[0008] Problems to be solved by the invention

[0009] According to Patent Document 1, the sliding rail and the inner housing are fixed to the outer housing with screws. In other words, the sunshade body includes a separate sliding rail, which is fixed with screws. This increases the number of components and the assembly time, potentially increasing manufacturing costs.

[0010] According to Patent Document 2, the support member needs to be assembled in a fixed position at a predetermined position between the two split parts. However, when the split parts are molded, for example, the heat generated during molding can cause thermal deformation of the split parts, resulting in shape deviations between the split parts. This makes assembly of the support member difficult. Therefore, a sliding mechanism for the sunshade that requires fewer parts, requires fewer assembly steps, and is easy to assemble is needed.

[0011] Means for solving problems

[0012] According to one feature of the present disclosure, a vehicle sun visor has a sun visor body having a first structural member and a second structural member that overlap in the thickness direction. A support shaft is inserted into the sun visor body, and the support shaft supports the sun visor body in a manner that allows it to rotate between a use position and a storage position. A housing is provided in the sun visor body, and the housing supports the support shaft in a rotatable manner and is slidably mounted to the sun visor body. A clamp is provided on the housing, and the clamp applies a force to the support shaft, thereby applying a force to the sun visor body toward the storage position. A guide rail is also provided, and the guide rail prevents the housing from falling off in the thickness direction relative to the first structural member. The guide rail is formed integrally with the first structural member in a manner that supports the housing slidably relative to the first structural member.

[0013] Therefore, the shell is supported on the sunshade body only by the guide rail formed integrally with the first structural member. Therefore, there is no need for a separate rail or the like, and there is no need for a process of screwing the rail or the like to the sunshade body. In this way, the sunshade can be manufactured at a low cost. The guide rail prevents the shell from falling off relative to the first structural member in the thickness direction. Therefore, the shell is held in a fixed posture only by the first structural member. Therefore, it can be held in a stable posture compared to the shell held between the first structural member and the second structural member. For example, it is possible to avoid the posture of the shell being affected by assembly errors between the first structural member and the second structural member or deviations in the sizes of the components. Moreover, by making the second structural member a simple structure and concentrating the functions and structures on the first structural member, the rigidity of the first structural member is increased, thereby making it possible to simplify the structure of the sunshade body. As a result, the manufacturing cost of the sunshade can be reduced.

[0014] According to a feature of one embodiment of the present disclosure, the guide rail includes a first track and a second track. The first track slidably supports a first end edge portion of the housing. The second track slidably supports a second end edge portion of the housing located on the opposite side of the first end edge portion. The first track and the second track are integrally formed with the first structural component. Therefore, the upper and lower ends of the housing in the sliding direction are supported by the first structural component, and thus the sliding load is stably maintained in the first structural component.

[0015] According to a feature of one embodiment of the present disclosure, the shell has a first end edge portion that engages with the guide rail. The guide rail has at least one cutout portion that can be inserted into the first end edge portion in the thickness direction of the first structural member. The guide rail has a guide rail body that is longer in the sliding direction. On the guide rail body, the first end edge portion of the shell is engaged in a manner that is slidable and cannot fall off in the thickness direction of the visor body. Therefore, the shell is installed on the guide rail by inserting the first end edge portion into the at least one cutout portion of the guide rail. Therefore, the shell can be easily installed on the guide rail without deforming the guide rail.

[0016] According to a feature of the present disclosure, the second structural component has a stop plate, which projects from the second structural component toward the end of the guide rail of the first structural component when the second structural component is mounted on the first structural component, and restricts the first end edge from falling off from at least one cutout portion of the guide rail. Therefore, when the shell is mounted on the guide rail, first, the first end edge of the shell is inserted into the at least one cutout portion. The first end edge is removed from the at least one cutout portion by sliding the shell relative to the guide rail. In this state, the second structural component is mounted on the first structural component. The stop plate of the second structural component can restrict the first end edge of the shell from detaching from the at least one cutout portion of the guide rail. Therefore, it is possible to prevent the shell from falling off from the guide rail after the shell is assembled on the guide rail.

[0017] According to a feature of the present disclosure, the first end edge portion has a first engaging portion and a second engaging portion on a straight line parallel to the sliding direction of the shell. The first engaging portion is formed at the first end portion or near the first end portion in the sliding direction of the shell, and has a first width in the sliding direction. The second engaging portion is formed at the second end portion or near the second end portion as the other end side of the first end portion, and has a second width in the sliding direction that is narrower than the first width. At least one cutout portion of the guide rail has a first cutout portion and a second cutout portion. The width of the first cutout portion in the sliding direction is wider than the first width, so that the first engaging portion can be inserted in the thickness direction. The width of the second cutout portion in the sliding direction is narrower than the first width and wider than the second width, so that the second engaging portion can be inserted in the thickness direction.

[0018] Therefore, the housing can be mounted on the guide rail in an installation position where the first engaging portion can be inserted from the first notch and the second engaging portion can be inserted from the second notch. Because the first engaging portion is wider than the second notch, it does not disengage from the second notch. Therefore, even if the housing moves away from the installation position and the first engaging portion reaches the second notch, it will not disengage from the guide rail. Furthermore, because the assembly direction of the housing can be visually determined from the two notches of different widths, the housing cannot be installed in the reverse direction.

[0019] According to one feature of the present disclosure, a first notch is formed at an end portion in a first sliding direction within a sliding region of a guide rail in which the housing slides. A first engaging portion is formed at or near the first end portion in the first sliding direction of the housing. The second structural component includes a stop plate that, when the second structural component is mounted on the first structural component, protrudes from the second structural component toward the end portion of the guide rail of the first structural component, thereby preventing the first end edge from falling out of the notch portion of the guide rail.

[0020] Therefore, when the shell is mounted on the guide rail, the convex portion or concave portion of the second end edge of the shell is arranged on the concave portion or convex portion provided to the second track for slidably supporting it, and further, the first engaging portion and the second engaging portion formed on the first end edge of the shell are respectively inserted into the first cutout portion and the second cutout portion of the first track for slidably supporting it. The shell is slid relative to the guide rail in such a manner that the first engaging portion moves away from the first cutout portion. In this state, the second structural component is mounted on the first structural component. Thus, the stop plate can prevent the first engaging portion from returning to the position of the first cutout portion. In this way, it is possible to prevent the first end edge of the shell from falling off from the cutout portion after the second structural component is assembled to the first structural component.

[0032] use Figure 1 、 Figure 2 An embodiment of the present invention will be described below. Figure 1 As shown, a vehicle sun visor 1 is mounted on a ceiling surface 20 near a front windshield 21 within a vehicle cabin. The vehicle sun visor 1 includes a sun visor body 1a and a mirror unit 12 provided on one surface of the sun visor body 1a. A support shaft 7, which rotatably supports the sun visor body 1a, is attached to the sun visor body 1a via a clamp 6 assembled to a housing 5. The sun visor body 1a rotatably supports the support shaft 7. The housing 5 is slidably mounted relative to the vehicle sun visor body 1a.

[0033] like Figures 1 to 7 As shown, the sun visor body 1a has a roughly rectangular shape and includes a first structural member 2 and a second structural member 3 in the form of flat plates that overlap in the thickness direction. A surface covering 13 is provided on the surface of the sun visor body 1a. The support shaft 7 is a roughly L-shaped rod, with the longitudinal axis 7a extending upward from the top of the transverse axis 7b in a manner roughly perpendicular to the transverse axis 7b. A bracket 11 is attached to the top of the longitudinal axis 7a, and the bracket 11 is mounted on the roof surface 20 of the vehicle. The transverse axis 7b is inserted from the side of the sun visor body 1a along the upper edge of the sun visor body 1a. The notched surface 7h provided on the small-diameter portion 7d of the support shaft is inserted through the opening 5f of the housing 5 and the opening 6a of the clamp 6, thereby being assembled to the clamp pressing portion 6b.

[0034] like Figure 1 、 Figure 2 As shown, the shaft 9 is generally cylindrical and is detachably retained by a hook 10 fixed to the ceiling surface 20. With the shaft 9 attached to the hook 10, the sun visor body 1a can be rotated about the shaft 9 and the transverse axis 7b between a use position P along the front windshield 21 and a storage position K along the ceiling surface 20. Furthermore, by removing the shaft 9 from the hook 10, the sun visor body 1a can be rotated about the longitudinal axis 7a. This allows the sun visor body 1a to rotate between a use position P along the front windshield 21 and a side position S along the side window glass 22.

[0035] like Figure 2 、 Figure 3 As shown, in order to make the visor body 1a slide along the horizontal axis 7b, a guide rail 4 is provided on the inner surface 2b of the first structural member 2 to support the housing 5 in a slidable manner. The guide rail 4 is substantially rectangular in shape. Figure 3 、 Figure 4 As shown, the guide rail 4 has a first rail 4a that projects downward from the upper edge 4p of the light shielding plate of the first structural member 2. The guide rail 4 has a plate-shaped base 4q at a position corresponding to the bottom side of the rectangle. The base 4q projects in a substantially vertical direction from the inner surface 2b of the first structural member 2. Figure 4 、 Figure 9 As shown, a second rail 4b is formed on the upper surface 4r of the base 4q so as to protrude and extend in parallel with the first rail 4a. The housing 5 is slidably supported by the first rail 4a and the second rail 4b.

[0036] like Figure 4 、 Figure 7 、 Figure 9 As shown, the second rail 4b protrudes from the base 4q toward the first rail 4a. The region 4m between the visor's upper edge 4p and the base 4q is elongated in the longitudinal direction of the visor body 1a, allowing the housing 5 to slide in the left-right direction. Within this region 4m, a protrusion 4n extending longitudinally from the visor's upper edge 4p and a plurality of longitudinal reinforcements 4h are provided. A sliding support 4i is formed at the connection between the first structural component 2 and the base 4q, protruding inward from the first structural component 2. The sliding support 4i extends in the left-right direction parallel to the second rail 4b or the base 4q.

[0037] like Figure 4 、 Figure 7 As shown, the protrusion 4n is located on the inner side of the first end edge portion (the first engaging portion 5g and the second engaging portion 5h) of the housing 5 and extends in parallel with the first rail 4a. Figure 9As shown, the protrusion 4n cooperates with the first rail 4a to slidably support the first end edge. Specifically, the protrusion 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.

[0038] Figure 3 The small diameter portion 7d of the horizontal shaft 7b shown is held by a clamp 6 assembled to the housing 5 (see Figure 10 ), the housing 5 is mounted on the guide rail 4. The horizontal shaft 7b is slidably supported on an inlet receiving portion 4f formed at the right end 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 is inserted. In this manner, the horizontal shaft 7b is retained via the inlet receiving portion 4f provided on the first structural member 2 and the clamp 6 assembled to the housing 5.

[0039] like Figure 3 、 Figure 11 As shown, a depth wall portion 4k is provided at the left end of the guide rail 4. The depth wall portion 4k has an opening portion 41 having a diameter smaller than the small diameter portion 7d of the horizontal axis 7b. A plurality of terminals 2a are provided at the left side of the depth wall portion 4k. For example, two terminals 2a are arranged in a horizontal direction at a position on the upper side relative to the horizontal axis 7b. Two other terminals 2a are arranged in a horizontal direction at a position on the lower side relative to the horizontal axis 7b. As shown in FIG. Figure 10 As shown, when the tip portion 7e of the support shaft 7 is inserted into the position where the terminal 2a is provided and the sunshade body 1a is in the use position P, the terminal portions 7f and 7g of the support shaft 7 contact the terminal 2a of the sunshade body 1a. When the sunshade body 1a is in the storage position K, the terminal portions 7f and 7g are separated from the terminal 2a.

[0040] like Figure 4 、 Figure 5 As shown, the clip 6 is formed by bending an integral leaf spring and grips the small-diameter portion 7d of the support shaft 7 at three points in the circumferential direction. The clip 6 urges and maintains the sun visor body 1a from rotating between its use position P along the front windshield 21 and its storage position K along the ceiling surface 20, centered around the small-diameter portion 7d. After the clip 6 is fitted into the housing 5, the support shaft small-diameter portion 7d is inserted into the clip 6 for assembly.

[0041] like Figure 3 、 Figure 4As shown, the housing 5 houses the clip 6. The housing 5 is slidable relative to the guide rail 4. The housing 5 includes a left longitudinal wall 5a and a right longitudinal wall 5b, and a clip retaining portion 5c at the bottom that connects the two longitudinal walls 5a and 5b. The housing 5 is formed, for example, from a resin. The two longitudinal walls 5a and 5b are spaced apart in the longitudinal direction of the first structural member 2. The width of the longitudinal wall 5a in the sliding direction is greater than the width of the longitudinal wall 5b in the sliding direction.

[0042] like Figure 4 、 Figure 7 As shown in FIG, the heads of the vertical wall portions 5a and 5b provided at the left and right ends of the housing 5 are substantially cylindrical. Figure 4 As shown, the tops of the vertical walls 5a and 5b are provided with first and second engaging portions 5g and 5h that protrude upward. The top surfaces 5v of the first and second engaging portions 5g and 5h are formed into a conical shape along the inner surface 2b of the first structural member 2. The vertical walls 5a and 5b are formed with openings 5e and 5f, each having an inner circumferential surface 5m with a generally circular cross-section.

[0043] like Figure 4 、 Figure 8 As shown, an elastic piece 5d is formed on the bottom surface 5q of the housing 5. This elastic piece 5d elastically collides with the upper surface 4r of the base 4q, thereby exerting frictional resistance. The elastic piece 5d is formed, for example, from a resin. The elastic piece 5d has an arc shape when viewed from the front. Bottom surface 5q has protrusions 5j formed at the left and right ends, respectively.

[0044] like Figure 4 、 Figure 6 As shown, the first rail 4a is provided with a rear-end cutout 4c and an entrance-side cutout 4d to facilitate assembly of the housing 5 onto the guide rail 4. The rear-end cutout 4c is located at the left end of the guide rail 4, between the left end of the first rail 4a and the rear-end wall 4k. The rear-end cutout 4c is wider than the first engaging portion 5g formed at the first end edge of the housing 5, thereby allowing the first engaging portion 5g to be inserted into the guide rail 4.

[0045] like Figure 4 As shown, the entrance-side cutout 4d is located on the right side, spaced apart from the rear-side cutout 4c. The entrance-side cutout 4d is wider than the second engaging portion 5h formed at the first end edge of the vertical wall 5b of the housing 5, allowing the second engaging portion 5h to be inserted into the guide rail 4. The entrance-side cutout 4d is narrower than the first engaging portion 5g of the housing 5. This prevents the first engaging portion 5g from detaching from the entrance-side cutout 4d when the first engaging portion 5g is located within the entrance-side cutout 4d.

[0046] like Figure 4 As shown, a stopper plate receiving area 4e is formed at the left end portion of the guide rail 4. The stopper plate receiving area 4e is located below the deep side cutout 4c and is used to receive the stopper plate 8 (see FIG. 1 ) of the second structural member 3 when the first structural member 2 and the second structural member 3 are overlapped and assembled together in the thickness direction. Figure 10 ) for storage. Figure 10 As shown, the stopper plate 8 is provided on the second structural member 3 in order to restrict the leftward movement of the housing 5 to the guide rail 4. The stopper plate 8 is, for example, in the shape of a quadrangular prism and protrudes from the inner surface 3b of the second structural member 3. Figure 4 、 Figure 10 As shown, an anti-drop protrusion 4j is provided on the upper surface 4r of the base 4q, and the anti-drop protrusion 4j extends from a position near the left end 4s of the second rail 4b in a manner parallel to the second rail 4b. Figure 8 As shown in FIG. 4 , a plurality of anti-drop protrusions 4j are provided on the upper surface 4r. Figure 8 、 Figure 9 When the housing 5 is assembled on the guide rail 4 as shown, it abuts against the horizontal extension 5 n , thereby preventing the housing 5 from falling off the guide rail 4 .

[0047] When the housing 5 is mounted on the guide rail 4, first, Figure 4 、 Figure 6 、 Figure 10 As shown in the figure, the lower part (second end edge) of the shell 5 is engaged with the second track 4b of the guide rail 4. In detail, the elastic piece 5d, the lower track protrusion 5i and the bottom surface protrusions 5j of the shell 5 are placed so as to pass through the upper side of the anti-falling protrusion 4j and contact the upper surface 4r of the base 4q. Next, the upper part (first end edge) of the shell 5 is engaged with the first track 4a of the guide rail 4. In detail, as shown in the figure, the elastic piece 5d, the lower track protrusion 5i and the bottom surface protrusions 5j of the shell 5 are placed so as to pass through the upper side of the anti-falling protrusion 4j and contact the upper surface 4r of the base 4q. Figure 7 、 Figure 8 As shown, the first engaging portion 5g formed on the first end edge of the vertical wall portion 5a of the housing 5 is inserted into the rear-end cutout 4c. Simultaneously, the second engaging portion 5h formed on the first end edge is inserted into the entrance-side cutout 4d. Furthermore, the first and second engaging portions 5g, 5h of the housing 5 are brought into contact with the protruding strip 4n. In this manner, the housing 5 is mounted on the guide rail 4.

[0048] Next, if Figure 4 、 Figure 8 As shown, after the housing 5 is mounted on the guide rail 4, it is slid to the right. Figure 8 As shown, the first engaging portion 5g of the housing 5 is separated from the deep side cutout portion 4c of the guide rail 4. Figure 10As shown, the first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the housing 5 are held between the first rail 4a and the protruding strip 4n. Furthermore, the second rail 4b is held between the elastic piece 5d of the housing 5 and the lower rail protrusion 5i. In this manner, the housing 5 is mounted on the guide rail 4 without elastic deformation.

[0049] like Figure 8 、 Figure 9 As shown, the front surfaces 5x of the bottom protrusions 5j at one end or both ends of the housing 5 abut against the anti-drop protrusions 4j. This allows the housing 5 and the second rail 4b to work together to more securely hold the housing 5. The rear protrusions 5p of the housing 5 abut against the sliding support 4i. Therefore, when the sunshade body 1a rotates between the use position P and the storage position K, the rear protrusions 5p restrict movement of the housing 5 in the thickness direction relative to the second rail 4b.

[0050] Next, if Figure 3 、 Figure 10 As shown, the horizontal shaft 7b is inserted from the opening 4g of the inlet receiving portion 4f along the guide rail 4. The horizontal shaft 7b passes through the openings 5e and 5f of the housing 5 (see Figure 4 ), the opening 6a of the clamp 6 and the opening 41 of the deep wall portion 4k. Finally, as Figure 11 As shown, the second structural member 3 is attached so as to overlap in the thickness direction with the first structural member 2. The first structural member 2 and the second structural member 3 are connected to each other by, for example, a connecting pin or the like.

[0051] At this time, the stopper plate 8 provided on the inner surface 3b of the second structural member 3 abuts against the stopper plate storage area 4e of the first structural member 2. This prevents the vertical wall portion 5a of the housing 5 from reaching the deep side cutout portion 4c. Figure 10 、 Figure 11 As shown, the inner surface 3b is provided with a protrusion 3c that protrudes toward the housing 5. The protrusion 3c can restrict the movement of the housing 5 in the thickness direction and the vertical direction. In this way, after the second structural member 3 is assembled to the first structural member 2, the housing 5 can be prevented from falling out of the rear-side cutout 4c and the entrance-side cutout 4d.

[0052] As mentioned above, if Figure 1 、 Figure 2 、 Figure 10As shown, the vehicle sun visor 1 includes a sun visor body 1a having a first structural member 2 and a second structural member 3 stacked in the thickness direction. A support shaft 7 is inserted into the sun visor body 1a, and the support shaft 7 supports the sun visor body 1a in a manner such that it can rotate between a use position P and a storage position K. Figure 3 、 Figure 7 As shown, a housing 5 is disposed within the sunshade body 1a. This housing 5 rotatably supports a support shaft 7 and is slidably mounted on the sunshade body 1a. A clamp 6 is attached to the housing 5, which applies force to the support shaft 7, thereby urging the sunshade body 1a toward the storage position K. A guide rail 4 is also provided to prevent the housing 5 from falling out of the first structural member 2 in the thickness direction. The guide rail 4 is integrally formed with the first structural member 2, slidably supporting the housing 5 relative to the first structural member 2.

[0053] Therefore, the housing 5 is supported on the sunshade body 1a solely by the guide rails 4 integrally formed with the first structural component 2. This eliminates the need for separate rails or other components, nor does the process of screwing the rails or other components to the sunshade body 1a require them. This allows for cost-effective manufacturing of the sunshade 1. The guide rails 4 prevent the housing 5 from falling out of the first structural component 2 in the thickness direction. Consequently, the housing 5 is held in a fixed position solely by the first structural component 2. This allows for a more stable position than a housing 5 held between the first structural component 2 and the second structural component 3. For example, this prevents the housing 5's position from being affected by assembly errors between the first and second structural components 2, or by variations in the dimensions of the components. Furthermore, by simplifying the second structural component 3 and concentrating its functions and structures on the first structural component 2, the rigidity of the first structural component 2 is increased, simplifying the structure of the sunshade body 1a. Consequently, the manufacturing cost of the sunshade 1 can be reduced.

[0054] like Figure 3 、 Figure 4 As shown, the guide rail 4 has a first track 4a and a second track 4b. The first track 4a supports the first engaging portion 5g and the second engaging portion 5h formed at the first end edge of the shell 5 in a slidable manner. The second track 4b supports the second end edge (5i, 5k, 5j) located on the opposite side of the first end edge of the shell 5 in a slidable manner. The first track 4a and the second track 4b are formed integrally with the first structural component 2. Therefore, the upper and lower ends of the shell 5 in the sliding direction are supported by the first structural component 2, so that the sliding load is stably maintained in the first structural component 2.

[0055] like Figure 4 、 Figure 10As shown, the housing 5 has a first engaging portion 5g and a second engaging portion 5h formed on the first end edge, which engage with the guide rail 4, and a second end edge. The guide rail 4 has a guide rail body (4a, 4b) that is elongated in the sliding direction. The first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the housing 5 are engaged on the guide rail body in a manner that allows sliding and prevents them from falling out in the thickness direction of the sunshade body 1a. Furthermore, cutouts (4c, 4d) are formed in the guide rail 4 to 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 sunshade body 1a.

[0056] Therefore, the housing 5 is mounted on the guide rail 4 by inserting the first engaging portion 5g and the second engaging portion 5h formed on the first end edge portion through the cutout portions (4c, 4d) of the guide rail 4. Therefore, the housing 5 can be easily mounted on the guide rail 4 without deforming the guide rail 4.

[0057] like Figure 10 、 Figure 11 As shown, the second structural component 3 includes a stopper plate 8 that prevents the first engaging portion 5g and the second engaging portion 5h formed on the first end edge from reaching the cutouts (4c, 4d) of the guide rail 4 when the second structural component 3 is mounted on the first structural component 2. Therefore, when the housing 5 is assembled onto the guide rail 4, the first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the housing 5 are first inserted into the cutouts (4c, 4d). The housing 5 is slid relative to the guide rail 4, causing the first engaging portion 5g and the second engaging portion 5h formed on the first end edge to move away from the cutouts (4c, 4d). In this state, the second structural component 3 is mounted on the first structural component 2. The stopper plate 8 of the second structural component 3 prevents the first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the guide rail 4 from reaching the cutouts (4c, 4d). Therefore, it is possible to prevent the housing 5 from falling off the guide rail 4 after the housing 5 is assembled to the guide rail 4 .

[0058] like Figure 4As shown, the first end 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 housing 5. The first engaging portion 5g is formed at the first end portion or near the first end portion in the sliding direction of the housing 5, and has a first width in the sliding direction. The second engaging portion 5h is formed at the second end portion or near the second end portion on the other end side of the first end portion, and has a second width in the sliding direction that is narrower than the first width. The cutout portion of the guide rail 4 has a first cutout portion 4c and a second cutout portion 4d. The width of the first cutout portion 4c in the sliding direction is wider than the first width, so that the first engaging portion 5g can be inserted in the thickness direction. The width of the second cutout portion 4d in the sliding direction is narrower than the first width and wider than the second width, so that the second engaging portion 5h can be inserted in the thickness direction.

[0059] Therefore, the housing 5 can be mounted on the guide rail 4 at an installation position where the first engaging portion 5g can be inserted from the first notch 4c and the second engaging portion 5h can be inserted from the second notch 4d. Since the first engaging portion 5g is wider than the second notch 4d, it will not detach from the second notch 4d. Therefore, even if the housing 5 moves away from the installation position and the first engaging portion 5g reaches the second notch 4d, it will not detach from the guide rail 4. In addition, since the assembly direction of the housing 5 can be visually known from the two notches of different widths, the housing 5 will not be installed in reverse.

[0060] like Figure 4 、 Figure 10 As shown, the first notch 4c is formed at the end of the guide rail 4 in the first sliding direction within the sliding area 4m of the housing 5. A first engaging portion 5g is formed at or near the first end of the housing 5 in the first sliding direction. The second structural member 3 includes a stopper plate 8 that projects from the second structural member 3 toward the end of the guide rail 4 of the first structural member 2 when the second structural member 3 is attached to the first structural member 2, thereby preventing the first end edge from disengaging from the notch (4c, 4d) of the guide rail 4. The stopper plate 8 has, for example, a quadrangular prism shape.

[0061] Therefore, when the housing 5 is mounted on the guide rail 4, the convex or concave portion of the second end edge of the housing is positioned over the concave or convex portion provided on the second rail 4b, and the first engaging portion 5g and the second engaging portion 5h formed on the first end edge of the housing are further inserted into the first notch 4c and the second notch 4d of the first rail 4a. The housing 5 is slid relative to the guide rail 4 in such a manner that the first engaging portion 5g moves away from the first notch 4c. In this state, the second structural component 3 is mounted on the first structural component 2. Thus, the stop plate 8 prevents the first engaging portion 5g from returning to the position of the first notch 4c. This prevents the first end edge of the housing 5 from falling out of the notch (4c, 4d) of the guide rail 4 after the second structural component 3 is assembled to the first structural component 2.

[0062] The present disclosure is not limited to the appearance and structure described in the above embodiments, and various changes, additions, and deletions can be made without changing the main purpose. Figure 4 、 Figure 7 As shown, the first and second engaging portions 5g and 5h are formed into convex shapes. The convex first and second engaging portions 5g and 5h are retained by the cooperation of the protrusion 4n and the first rail 4a. Alternatively, the first engaging portion 5g of the housing 5 may be formed into a concave portion. Specifically, for example, a structure may be adopted in which the first engaging portion 5g of the housing 5 is formed into a concave portion, and a convex portion that engages with the concave portion is formed on the first rail 4a side.

[0063] like Figure 4 、 Figure 6 、 Figure 9 As shown, the housing 5 is mounted on the guide rail 4 by inserting the first engaging portion 5g and the second engaging portion 5h formed at the first end edge portion through the cutout portion (4c, 4d) of the guide rail 4. For example, in addition to the cutout portion (4c, 4d) of the first rail 4a, a cutout portion may be provided in the second rail 4b. In this case, the housing 5 can be mounted on the guide rail 4 by inserting the first engaging portion 5g and the second engaging portion 5h into the cutout portion (4c, 4d) of the first rail, and inserting the third engaging portion formed at the second end edge portion on the opposite side of the first end edge portion into the cutout portion of the second rail 4b. Furthermore, the widths of the cutout portions (4c, 4d) of the first rail and the cutout portion of the second rail 4b may be set to be cutout portions of different widths.

[0064] like Figure 4 、 Figure 8 、 Figure 9As shown, the housing 5 is mounted by fitting the recess 5k of the housing 5 with the convex second rail 4b. Alternatively, the second rail 4b may be formed into a mountain or trapezoidal shape, and the housing 5 may be mounted by setting the recess 5k corresponding thereto into a corresponding shape.

[0065] like Figure 4 、 Figure 7 As shown, the housing 5 has a first engaging portion 5g and a second engaging portion 5h at the top of the vertical walls 5a and 5b, respectively, and a lower rail protrusion 5i, a bottom surface protrusion 5j, and an elastic piece 5d on the bottom surface. Alternatively, for example, the first rail 4a can be positioned on the upper surface 4r of the base 4q, and the second rail 4b can be positioned at the upper edge of the light shield, thereby turning the housing 5 upside down. In this case, the top surface 5v of the first engaging portion 5g and the top surface 5w of the second engaging portion 5h can be formed parallel to the upper surface 4r.

[0066] For the first structural member 2 and the second structural member 3, for example, the two cores may be formed of a hard resin, and the second structural member 3 may be formed of a foamed resin. Figure 10 As shown, the first structural member 2 and the second structural member 3 are separate components. Alternatively, for example, the first structural member 2 and the second structural member 3 may be connected via a hinge formed of resin, thereby forming an integral body. In this case, the guide rail 4 may be provided on either the first structural member 2 or the second structural member 3 side.

[0067] like Figure 10 As shown, the stopper plate 8 is provided on the second structural member 3. Alternatively, the stopper plate 8 may be provided as a separate body. The shape of the stopper plate 8 may be adapted to the shape and size of the stopper plate storage area 4e, instead of a quadrangular prism.

[0068] like Figure 3 、 Figure 4 、 Figure 11 As shown, instead of the stop plate 8, an opening portion 41 having a smaller diameter than the top end portion 7e of the transverse axis 7b may be formed on the deep wall portion 4k, so that the top end portion 7e of the transverse axis 7b is not inserted into the opening portion 41 but is stopped at the opening portion 41 to function as the stop plate 8.
