Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the attachment structure of the side visor of Patent Document 1, since the edge portion of the sheet metal hole bites into the boss, when an external force is applied to the side visor, the boss may be scraped at the edge portion of the sheet metal hole, etc., and the assembled state of the side visor and the bracket may become unstable.

[0005] Therefore, an object of the present invention is to provide an attachment structure of a side visor that can stably maintain the assembled state with an attachment member even when an external force is applied to the side visor.

[0006] To achieve the above objective, the invention described in claim 1 is a mounting structure for a side visor that includes a side visor comprising a long, strip-shaped flange and a canopy formed in a long, strip shape along the flange, and a mounting member used when attaching the side visor to the window frame of an automobile, wherein the side visor is provided with a projection that protrudes toward the window frame when attached to the window frame, and the base end of the projection is such that, when viewed from the window frame side when attached to the automobile, Diamond shape It has, and as it moves toward the tip of the projection It tapers and widens. The mounting member is equipped with a retaining part, resin The plate-shaped member has a window frame hook portion formed at one end for hooking onto a window frame, and an engagement portion formed at the other end for engaging with a side visor. The engagement portion has a hole through which a projection including a retaining portion can be inserted when the mounting member is in a first orientation relative to the projection, and a hole through which a projection cannot be inserted when the mounting member is in a second orientation relative to the projection. The hole is defined as having an arbitrary point in its inner diameter as the first hole reference point, and the distance between the first hole reference point and the second hole reference point, which is a point in the inner diameter of the hole to which a line segment parallel to the tangent at the first hole reference point becomes tangent, is defined as an arbitrary point on the outer surface of the projection, within a range from the boundary with the awning to the thickness of the mounting member, and less than or equal to the thickness of the mounting member, as the first projection reference point. The mounting member is formed such that the distance between the first projection reference point and the second projection reference point, which is a point on the outer surface of the projection whose height from the boundary between the projection and the eaves body, where a line segment parallel to the tangent to the first projection reference point is tangent, is the same as that of the first projection reference point, is the maximum distance between the two points. The mounting member is positioned in a first orientation relative to the projection, and the projection is inserted into the hole. Subsequently, by rotating the projection around the projection's protruding direction as an axis, the mounting member is rotated in a second orientation, transitioning from the first orientation. In this second orientation, the mounting member's rotation is suppressed by pressure from the inner surface of the hole against both end faces of the projection where the distance between the first projection reference point and the second projection reference point is maximum, and it is also prevented from coming out of the hole by a retaining portion.

Subsequently, by rotation around the projection's protruding direction as an axis, in the second orientation, which is the transition from the first orientation, the mounting member's rotation is suppressed by pressure from the inner surface of the hole against both end faces of the projection where the distance between the first projection reference point and the second projection reference point is maximum, and it is also prevented from coming out of the hole by the retaining portion. It is characterized by the following: [Effects of the Invention]

[0007] Claim 1 , and claim 2According to the invention described above, after inserting the projection provided on the side visor into the hole of the mounting member which is oriented in the first direction, the mounting member is prevented from coming off simply by changing the orientation from the first to the second direction, thus making it easy to assemble the side visor and the mounting member. Furthermore, since the assembled state of the side visor and the mounting member is not such that the periphery of the hole is bitten into the projection as in the conventional method, the projection will not be scraped by the mounting member even if an external force is applied to the side visor, and a stable assembled state of the side visor and the mounting member can be maintained. Also, When rotating the mounting member from the first orientation to the second orientation, the inclination of the retaining portion guides the mounting member closer to the inner surface of the canopy, allowing the mounting member to be assembled closer to the inner surface of the canopy and thus making the assembled state more stable.

Figure 6(a) is an explanatory diagram showing the area around the protrusion of the side visor with the mounting member assembled, and Figure 6(b) is an explanatory diagram showing the range in which a pressing force is generated from the mounting member to the protrusion. Note that the directions shown in the figures indicate the direction when the visor is mounted on a vehicle.

[0010] As shown in Figure 1(a), the side visor 1 is attached to the window frame 2 of the automobile and functions as a sunshade and rain shield. The side visor 1 includes a long, strip-shaped flange portion 3 and a long, strip-shaped canopy body 4 formed along the flange portion 3. As shown in Figures 1(b) and 2(a), the canopy body 4 on the window frame 2 side when attached to the automobile is provided with a projection 5 that is integrally provided with the side visor 1 and protrudes toward the window frame 2. The side visor 1 is attached to the projection 5 by assembling the mounting member 6 (described later) and is fixed to the window frame 2 by the mounting member 6 and fixing means such as double-sided tape T.

[0011] As shown in Figures 2(a), 4(a) and 5(a) and 5(b), the base end of the projection 5 of the side visor 1 is formed in a roughly diamond shape when viewed from the window frame 2 side when the projection 5 is attached to the automobile. The projection 5 also has retaining portions 7 on the front and rear sides that are tapered and inclined so as to widen towards the tip.

[0012] The attachment member 6 is, for example, a plate-like member formed by bending a material having elasticity such as polyamide resin, polypropylene resin, polyethylene resin, acrylonitrile butadiene styrene resin, or acrylate styrene acrylonitrile resin. As shown in FIGS. 1(b) and 2(c), a window frame engaging portion 8 that is hooked on the window frame 2 is formed at one end, and an engaging portion 9 with which the side visor 1 can be engaged is formed at the other end. As shown in FIGS. 4(a), (b) and FIGS. 5(a), (b), a substantially rhombic hole portion 10 is formed in the engaging portion 9.

[0013] Subsequently, the dimensional relationship between the protrusion 5 and the hole 10 when viewed from the window frame 2 side in the state of being attached to the vehicle will be described. For this purpose, as shown in FIG. 3(a), on the outer surface of the protrusion 5, an arbitrary point within a range not exceeding the plate thickness of the attachment member 6 from the boundary with the shield 4 is defined as the first protrusion reference point A1. Further, a point on the outer surface of the protrusion 5 where a line segment AL2 parallel to the tangent line AL1 at the first protrusion reference point A1 serves as the tangent line is defined as the second protrusion reference point A2. And the distance between the first protrusion reference point A1 and the second protrusion reference point A2 is defined as the distance a. Also, as shown in FIG. 3(b), an arbitrary point on the inner diameter of the hole 10 is defined as the first hole reference point B1. Further, a point on the inner diameter of the hole 10 where a line segment BL2 parallel to the tangent line BL1 at the first hole reference point B1 serves as the tangent line is defined as the second hole reference point B2. And the distance between the first hole reference point B1 and the second hole reference point B2 is defined as the distance b.

[0014] As shown in Figure 4(a), if the distance between the front end of the front retaining portion 7 on the front side of the projection 5 and the rear end of the rear retaining portion 7 on the rear side is defined as line segment L1, and the distance b when the front end of the hole 10 is defined as the first hole reference point B1 and the rear end as the second hole reference point B2 is defined as line segment D1, then the projection 5 and the hole 10 are formed such that line segment L1 is shorter than line segment D1. In addition, if the distance b when the upper end of the hole 10 is defined as the first hole reference point B1 and the lower end as the second hole reference point B2 is defined as line segment D2, then the projection 5 and the hole 10 are formed such that line segment L1 is longer than line segment D2. On the other hand, if the distance between the upper end and lower end of the projection 5 is defined as line segment L2, then the projection 5 and the hole 10 are formed such that line segment L2 is shorter than line segment D2. By giving the projection 5 and the hole 10 such a dimensional relationship, the projection 5 can be inserted into the hole 10 in the first orientation described later, and the projection 5 cannot be inserted into the hole 10 in the second orientation.

[0015] Furthermore, the first projection reference point A1 is defined as the point on the outer surface of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4 at the front retaining portion 7 of the projection 5. The second projection reference point A2 is defined as the point on the outer surface of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4, where the line segment AL2, which is parallel to the tangent line AL1 at the first projection reference point A1, is tangent to the point on the outer surface of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4 at the rear retaining portion 7 of the projection 5. The distance a between the first projection reference point A1 and the second projection reference point A2 is defined as line segment L3. At this time, line segment L3 is the maximum of any distance a on the outer surface of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4. The projection 5 and the hole 10 are formed such that line segment D2 is shorter than line segment L3. Furthermore, the hole 10 is provided in a orientation such that the line segment D1 is parallel to the longitudinal direction of the mounting member 6.

[0016] The specific dimensions of the projection 5 are as follows: The protruding width of the projection 5 from the inner surface of the eaves body 4 is set within the range of 1 to 10 mm, preferably 4 mm. The line segment L1 is set within the range of 3 ≤ L1 < 13 (mm), preferably 8 mm. The line segment L2 is set within the range of 2 ≤ L3 ≤ 8 (mm), preferably 5 mm. The line segment L3 is set within the range of 3.5 ≤ L2 ≤ 8.5 (mm), preferably 5.5 mm. Also, the dimensions of each part in the engaging part 9 of the mounting member 6 are as follows. The plate thickness of the mounting member 6 is set within the range of 0.5 to 2 mm, preferably 0.5 mm. The line segment D1 of the hole 10 is set within the range of 3 < D1 ≤ 13 (mm), preferably more than 8 mm. The line segment D2 is set within the range of 3 ≤ D2 ≤ 8 (mm), preferably 5 mm.

[0017] Also, as shown in Fig. 2(b), the projection 5 is formed such that the tip side of the projection 5 has a dome shape in the cross-sectional shape with the central longitudinal section line in the state of being attached to the automobile, that is, the line segment L2 as the cross-section line. By adopting such a shape with a narrowed tip, when inserting the projection 5 into the hole 10 of the mounting member 6, even if the alignment is ambiguous, the insertion can be started, so the insertion can be easily performed.

[0018] Subsequently, a method of attaching the side visor 1 to the window frame 2 will be described. First, the side visor 1 and the mounting member 6 are assembled. As shown in Fig. 4(a), the projection 5 is inserted from the outside of the mounting member 6 toward the window frame side into the hole 10 formed in the engaging part 9 of the mounting member 6. At this time, the mounting member 6 is oriented such that the line segment D1 of the hole 10 is parallel to the line segment L1. This orientation is the first orientation in this embodiment. In Fig. 4 of the embodiment, the orientation in which the window frame hook part 8 is located behind the engaging part 9 is shown as the first orientation, but the orientation in which the window frame hook part 8 is located in front of the engaging part 9 may also be regarded as the first orientation. That is, the orientation obtained by rotating the mounting member 6 shown in Fig. 4 by 180 degrees along the inner surface of the eaves body 4 of the side visor 1 with the protruding direction of the projection 5 as the axis may also be regarded as the first orientation.

[0019] Next, with the projection 5 still inserted through the hole 10 of the mounting member 6 in the first orientation, the mounting member 6 is rotated 90 degrees along the inner surface of the canopy 4 of the side visor 1, with the projection 5 as the axis, so that the window frame hook portion 8 is above the engaging portion 9. As a result, the mounting member 6 engages with and is assembled to the side visor 1, as shown in Figure 6(a).

[0020] At this time, as the mounting member 6 rotates, the inclined surface of the retaining portion 7 comes into contact with the inner surface of the hole portion 10, as shown in Figure 5(b). The tapered inclination guides the mounting member 6 toward the inner surface of the awning 4, allowing the side visor 1 and the mounting member 6 to be assembled at a position closer to the inner surface of the awning 4. Furthermore, the inclination of the retaining portion 7 widens towards the tip of the projection 5, causing a force to be exerted on the mounting member 6 toward the base end of the projection 5, i.e., toward the inner surface of the awning 4. As a result, the mounting member 6 is prevented from moving toward the window, thus preventing it from coming off, and rattling relative to the side visor 1 is suppressed.

[0021] Furthermore, since line segment D2 is shorter than line segment L3, from the first orientation, after the inclined surface of the retaining portion 7 comes into contact with the inner surface of the hole 10, the hole 10 is pushed open by the outer surface of the projection 5, i.e., both end faces of line segment L2, until the mounting member 6 is assembled with the side visor 1 rotated 90 degrees, as shown in Figures 5(a) and 6(a). At this time, since the mounting member 6 is made of an elastic material, a pressing force is applied to the projection 5 from the hole 10. Therefore, rotation is suppressed by the pressing force from the inner surface of the hole 10 against both end faces of the projection 5, i.e., the end faces of line segment L3, where the distance a between an arbitrary first projection reference point A1 and a second projection reference point A2 at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the visor 4 is maximized. Furthermore, even without rotating the mounting member 6 by 90 degrees, in the range where the distance b between any first hole reference point B1 and the second hole reference point B2 of the hole 10 is shorter than the line segment L3, a pressing force is generated by the hole 10 against the projection 5, thus suppressing the rotation of the mounting member 6. In Figure 6(b), the range in which the distance b between any first hole reference point B1 and the second hole reference point B2 of the hole 10 is shorter than the line segment L2, in other words, the range in which a circle with line segment L2 as its diameter overlaps with the engagement portion 9 around the hole 10 is indicated by a diagonal line. Therefore, if both end faces of line segment L2 are located within the range indicated by the diagonal line in Figure 6(b), a pressing force will be generated from the mounting member 6 against the projection 5. The orientation of the mounting member 6 in this state in which a pressing force is generated from the mounting member 6 against the projection 5 is the second orientation in this embodiment. However, in this embodiment, the state in which the mounting member 6 is rotated 90 degrees from the first orientation is preferred because it provides the greatest stability. In this way, the side visor 1 and the mounting member 6 can be easily assembled by simply inserting the projection 5 through the hole 10 of the mounting member 6 in the first orientation and changing the mounting member 6 from the first orientation to the second orientation.

[0022] After assembling the side visor 1 and the mounting member 6, the window frame hook portion 8 of the mounting member 6 is hooked onto the window frame 2, and the side visor 1 is fixed to the window frame 2 using a fixing means such as double-sided tape T. In this way, the side visor 1 is attached to the window frame 2. In this case, since the mounting member 6 is not biting into the projection 5, even if an external force is applied to the side visor 1, the projection 5 will not be scraped by the periphery of the hole 10, and a stable assembled state between the side visor 1 and the mounting member 6 can be maintained.

[0023] The mounting structure of the side visor 1 in the above form includes a side visor 1 including a long, strip-shaped flange portion 3 and a long, strip-shaped visor body 4 formed along the flange portion 3, and a mounting member 6 used when attaching the side visor 1 to the window frame 2 of an automobile, the side visor 1 is provided with a projection 5 that protrudes toward the window frame 2 when attached to the window frame 2, the projection 5 has a base end that is substantially diamond-shaped when viewed from the window frame 2 side when attached to an automobile, and a retaining portion 7 that tapers and inclins to widen toward the tip of the projection 5, the mounting member 6 is a plate-shaped member molded from an elastic material, with a window frame hook portion 8 formed at one end that can be hooked onto the window frame 2, and an engaging portion 9 formed at the other end for engaging with the side visor 1, the projection 5 including the retaining portion 7 can be inserted into the engaging portion 9 when the mounting member 6 is in a first orientation relative to the projection 5, and when the mounting member 6 is in a second orientation relative to the projection 5 A hole 10 is formed through which 5 cannot be inserted, and the line segment D2, which is the interval b when the upper end of the hole 10 is taken as the first hole reference point B1 and the lower end as the second hole reference point B2, is less than or equal to the line segment L3, which is the interval a when the first projection reference point A1 is taken at the point on the front side of the retaining portion 7 of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4 and the second projection reference point A2 is taken at the point on the rear side of the retaining portion 7 of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4. Formed to a certain length, the mounting member 6 is positioned in a first orientation relative to the projection 5. The projection 5 is then inserted through the hole 10, and subsequently, by rotation around the projection direction of the projection 5, in the second orientation transitioned from the first orientation, the mounting member 6 is prevented from rotating by pressure from the inner surface of the hole 10 against both end faces of the projection 5 where the distance a between the first projection reference point A1 and the second projection reference point A2 is maximum, and is also prevented from coming out of the hole 10 by the retaining portion 7.

[0024] With the mounting structure of the side visor 1 configured in this way, after inserting the projection 5 provided on the side visor 1 into the hole 10 of the mounting member 6 which is in the first orientation, the projection 5 is prevented from coming off simply by turning the mounting member 6 to the second orientation, thus making it easy to assemble the side visor 1 and the mounting member 6. Furthermore, since the assembled state of the side visor 1 and the mounting member 6 is not such that the periphery of the hole 10 bites into the projection 5 as in the conventional method, the projection 5 will not be scraped by the mounting member 6 even if an external force is applied to the side visor 1, and a stable assembled state of the side visor 1 and the mounting member 6 can be maintained. Furthermore, when rotating the mounting member 6 from the first orientation to the second orientation, the inclination of the retaining portion 7 guides the mounting member 6 to the inner surface of the canopy body 4, allowing the mounting member 6 to be assembled closer to the inner surface of the canopy body 4, thus making the assembled state more stable.

[0025] Figure 7(a) is an explanatory diagram showing the area around the protrusion of the side visor of Modified Example 1, and Figure 7(b) is an explanatory diagram showing the area around the protrusion of the side visor of Modified Example 1 with the mounting member assembled. Figure 8(a) is an explanatory diagram showing the area around the protrusion of the side visor when the mounting member is assembled to the side visor of Modified Example 1 in the second orientation, and Figure 8(b) is a line DD end view of Figure 8(a). Configurations that show the same effect as those shown in Figures 1 to 5 are denoted by the same reference numerals as in Figures 1 to 5, and their explanations are omitted. The directions shown in the figures indicate the direction when the component is mounted on an automobile.

[0026] As shown in Figures 7(a), (b) and 8(a), (b), the side visor 1a is provided with a projection 5a that has a circular shape with protrusions at the front and rear when viewed from the window frame 2 side when installed on the vehicle. On both the front and rear sides of the cylindrical portion of the projection 5a, there are protrusions that serve as retaining portions 7a, which taper and widen towards the tip of the projection 5a. The retaining portions 7a also function as ribs that reinforce the projection 5a. The line segment L4 connecting the front end of the front retaining portion 7a and the rear end of the rear retaining portion 7a of the projection 5a is shorter than the line segment D1 of the hole 10 of the mounting member 6, and longer than the short line segment D2 of the hole 10. Furthermore, on the outer surface of the projection 5a, the line segment L5 is formed such that, when the distance a between any first projection reference point A1 and second projection reference point A2 at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is set to the maximum length, the front end of the front retaining portion 7a at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4 and the rear end of the rear retaining portion 7a at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is set to the first projection reference point A1 and the second projection reference point A2, respectively, and the distance a is set to the maximum length, the line segment L5 is formed such that it is slightly longer than the line segment D2 of the hole 10.

[0027] The assembly of the side visor 1a and the mounting member 6, and the attachment to the window frame 2, are carried out in the same manner as in the embodiment described above. Therefore, after inserting the projection 5a provided on the side visor 1a into the hole 10 of the mounting member 6 which is in the first orientation, the mounting member 6 is simply rotated to the second orientation to prevent it from coming off, thus making it easy to assemble the side visor 1a and the mounting member 6. Furthermore, since the assembled state of the side visor 1a and the mounting member 6 is not such that the periphery of the hole 10 bites into the projection 5a as in the conventional method, the projection 5a will not be scraped by the mounting member 6 even if an external force is applied to the side visor 1, and a stable assembled state of the side visor 1a and the mounting member 6 can be maintained. Furthermore, even without rotating the mounting member 6 by 90 degrees, in the above embodiment, as shown by the diagonal lines in Figure 6(b), in the range where the distance b between any first hole reference point B1 and the second hole reference point B2 of the hole 10 is shorter than the line segment L5, a pressing force is generated by the hole 10 on the projection 5a, thus suppressing the rotation of the mounting member 6. Therefore, the orientation of the mounting member 6 in the state where a pressing force is generated from the mounting member 6 on the projection 5a is the second orientation in Modified Example 1. However, in Modified Example 1, the state in which the mounting member 6 is rotated 90 degrees from the first orientation is preferable because it provides the greatest stability.

[0028] Figure 9(a) is an explanatory diagram showing the area around the protrusion of the side visor of Modified Example 2, and Figure 9(b) is an explanatory diagram showing the area around the protrusion of the side visor of Modified Example 2 with the mounting member assembled. Figure 10(a) is an explanatory diagram showing the area around the protrusion of the side visor when the mounting member is assembled to the side visor of Modified Example 2 in the second orientation, and Figure 10(b) is an EE line end view of Figure 10(a). Figure 11 is an FF line end view of Figure 10, and is an explanatory diagram showing the movement of the mounting member when attaching the mounting member to the protrusion of Modified Example 2. Configurations that show the same effect as the configurations shown in Figures 1 to 5 are denoted by the same reference numerals as in Figures 1 to 5, and their explanations are omitted. The directions shown in the figures indicate the direction when the component is mounted on an automobile.

[0029] As shown in Figures 9(a), (b), 10(a), (b), and 11, the side visor 1b is provided with a projection 5b having a roughly diamond-shaped base end 11 with vertices on the top, bottom, left, and right when viewed from the window frame 2 side when installed on a vehicle. Furthermore, an extended portion 12, which is circular when viewed from the window frame 2 side when installed on a vehicle, extends downward from the tip side of the base end 11 of the projection 5b, with the upper vertex of the projection 5b as its upper end. In addition, the projection 5b has an inclined surface that tapers and widens towards the tip side of the extended portion 12. This inclined surface is the retaining portion 7b in the modified example 2. The line segment L6 connecting the front and rear ends of the extended portion 12 of the projection 5b is formed to be shorter than the line segment D1 of the hole 10 of the mounting member 6. On the other hand, if the distance between the upper and lower ends of the projection 5 at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is defined as line segment L7, then line segment L7 is formed to be shorter than line segment D2. Furthermore, on the outer surface of the projection 5b, if the distance a between any first projection reference point A1 and second projection reference point A2 at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is defined as the front end of the front retaining portion 7b at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4, and the rear end of the rear retaining portion 7b at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4, is defined as the first projection reference point A1 and the second projection reference point A2, where the distance a is the maximum length, then line segment L6 is formed to be slightly longer than the line segment D2 of the hole 10.

[0030] Next, we will explain how to assemble the side visor 1b and the mounting member 6. First, the mounting member 6 is oriented so that the line segment D1 of the hole 10 is parallel to the line segment L6. This orientation is the first orientation in the modified example 2. Then, while maintaining the first orientation, as shown in Figure 11, the mounting member 6 is tilted toward the window side and moved to slide upward from below relative to the expanded portion 12 of the projection 5b (arrow A), so that the expanded portion 12 fits into the hole 10.

[0031] Next, the mounting member 6 is returned to its original position (arrow B) so that it is in contact with the inner surface of the canopy 4 of the side visor 1b. Then, as shown in Figure 9(b), the mounting member 6 is rotated 90 degrees along the inner surface of the canopy 4 of the side visor 1b, with the projection direction of the projection 5b as the axis, so that the window frame hook portion 8 is above the engagement portion 9, thus adopting the second orientation. As a result, the mounting member 6 engages with and is assembled to the side visor 1. Therefore, after inserting the projection 5b provided on the side visor 1b through the hole 10 of the mounting member 6 in the first orientation, the mounting member 6 is simply rotated to the second orientation to prevent it from coming loose, making it easy to assemble the side visor 1b and the mounting member 6. Furthermore, since the assembly state between the side visor 1b and the mounting member 6 is not such that the periphery of the hole 10 bites into the projection 5b as in the conventional design, the projection 5b will not be scraped by the mounting member 6 even when an external force is applied to the side visor 1, and a stable assembly state between the side visor 1b and the mounting member 6 can be maintained.

[0032] The subsequent attachment to the window frame 2 is carried out in the same manner as in the embodiment described above. Furthermore, even without rotating the mounting member 6 by 90 degrees, in the above embodiment, as shown by the diagonal lines in Figure 6(b), in the range where the distance b between any first hole reference point B1 and the second hole reference point B2 of the hole 10 is shorter than the line segment L6, a pressing force is generated by the hole 10 on the projection 5b, thus suppressing the rotation of the mounting member 6. Therefore, the orientation of the mounting member 6 in the state where a pressing force is generated from the mounting member 6 on the projection 5b is the second orientation in Modified Example 2. However, in Modified Example 2, the state in which the mounting member 6 is rotated 90 degrees from the first orientation is preferable because it provides the greatest stability.

[0033] The present invention has been described above based on illustrated examples, and its technical scope is not limited thereto. For example, although the embodiment describes installation on the window frame of the left front door of an automobile, the mounting structure for the side visor of the present invention is applicable to both the left and right front side visors and the left and right rear side visors. Furthermore, the projection may be provided integrally with the side visor as described above, or it may be provided as a separate part. Also, the projection may be provided anywhere on the inside of the side visor when it is mounted on the vehicle, and there may be one or multiple projections. In addition, the shape of the projection can be arbitrarily designed, except for the base end being a perfect circle, as long as the side visor and mounting member can be assembled by changing the orientation of the mounting member from a first orientation to a second orientation. Moreover, the projection may be provided with reinforcing means such as ribs, and the ribs may also function as retaining parts. Furthermore, the inclined shape of the retaining portion may be flat, curved, or a combination of flat and curved surfaces, or it may have irregularities such as protrusions, and three or more retaining portions may be provided as long as they are provided on the outer circumference of the protrusion. Furthermore, the shape of the base end of the projection and the shape of the extension can be arbitrarily designed, as shown in the modified example 2 above, as long as the mounting member and the side visor can be assembled in such a way that after the mounting member passes through the extension, the extension restricts the mounting member in the first orientation from moving in the direction of projection. Furthermore, the shape of the hole only needs to be such that a projection including a retaining portion can be inserted in the first orientation, but the projection cannot be inserted in the second orientation, and can be arbitrarily designed as an ellipse, polygon, etc. In addition, means to prevent over-rotation of the mounting member may be provided on at least one of the projection, visor, or mounting member, separate from the hole. Furthermore, the rotation angle between the first orientation and the second orientation can be arbitrarily set to the optimal angle based on the combination of shapes of the projection, the retaining part, and the hole. Furthermore, the second orientation only needs to be within the range where a pressing force is generated on the projection by the hole, and it is not necessarily required that the positions of the concave part, such as the apex of the hole, and the convex part, such as the apex of the projection, coincide. Furthermore, the material of the mounting member can be selected from materials other than resin, as long as it has sufficient rigidity for mounting the side visor to the window frame, as well as elasticity that allows the hole to expand and contract with rotation between the first and second orientations, that is, a material that can generate a pressing force on the protrusion due to the inner surface of the hole. In addition, the entire mounting member may be formed from an elastic material, or only the engaging portion or the periphery of the hole may be molded from an elastic material.
