DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings by using embodiments. Example 1 The present example relates to each structure of a gutter cover and a gutter body, and a gutter structure obtained by combining both structures. (1) Structure of Gutter Cover FIG. 1 shows a lower cover surface portion, a lower cover curved surface portion extending continuously upward from the lower cover surface portion, and a lower cover curved surface portion continuously extended upward from the lower cover curved surface portion. FIG. 2 is a front view showing a gutter cover provided with a pair of concave lid grooves arranged along the longitudinal direction of the gutter cover, and FIG. 2 is a partially enlarged sectional view of a main part thereof.

As shown in FIG. 1, the gutter cover 110 has lower cover surface portions 115a and 115b and these lower cover surface portions 11a and 115b.
Lower cover curved surface portions 114a, 114b extending upward continuously from 5a, 115b, and extending upward continuously from the lower cover curved surface portions 114a, 114b, and extending in the longitudinal direction of the side groove cover. A pair of concave lid grooves 1 arranged along
13a, 113b and these concave lid grooves 113a,
Is extended upward continuously to 13b upper side cover Bay songs face 1
12a and 112b and the upper lid curved surface portion 112
The upper lid inclined surface portions 111a and 111b extend upward continuously from the upper and lower portions 112a and 112b. Then, as shown in FIG. 2, the lid lower surface portions 115a and 115b are
01 are opposed to each other at a small interval G2 with respect to the lower frame portions 106a and 106b of the main body 01.

As shown in FIG. 2, the gutter cover 1 having such a structure is used.
10 is placed on the gutter frame 101, the gutter lid 110
The lower lid curved surface portion 114a is supported in line contact with the corner P of the lower side frame curved surface portion 105a of the side groove frame 101 that is curved with a degree of curvature smaller than the degree of curvature (curvature). . Here, the effective thickness of the gutter cover 110 up to the above-mentioned corner portion P of the gutter frame body 101 with which the line contact is made is a thickness with which sufficient strength can be obtained.
Even if the vehicle runs on it, it can withstand sufficiently.

As described above, the lower side body curved surface portion 105a
Due to the above-mentioned line contact and the degree of curvature between the lower side lid curved surface portion 114a and the degree of curvature, the side groove lid slightly pushes open both side walls of the side groove body to the left and right, and the side groove lid sinks down, so that it looks like a crab pinch. Since the wedge effect is obtained, the gutter cover 110 does not rattle in the gutter body 101 at all, and the generation of noise pollution can be reliably avoided.

As shown in FIGS. 2 and 3, the lower cover surface portion 115a of the side groove cover 110 is located below the lower end P to be in contact with the lower groove surface portion 106a of the side groove body 101. Because the minute interval G2 is maintained,
Even if the wheel of the vehicle rides on the gutter lid 110 and a load is concentrated on a part of the gutter lid 110, the gutter lid 110 tends to jump up.
Will abut against the opposing lower body surface portion 106a, so that further upward movement is restricted.

As shown in FIG. 4, the lid lower surface portions 115a and 115b of the gutter cover 1 are connected to both end surfaces (end surfaces not in contact with the gutter body) 117a and 117b of the gutter cover 110.

Reinforcing bars are arranged at predetermined positions on the gutter 110 (not shown). And this rebar is arrange | positioned on the line contact point P, and it has a structure excellent in intensity | strength.

With such a gutter cover fitted into the gutter body, as shown in FIGS. 2, 5 and 6, the gutter cover 1 is formed.
The lower point (point P in FIG. 2) of the curved surface portion of the lid 10 is that the four corners of the expected contact line portion are in line contact with the curved surface portions (103a to 105a, 103b to 105b) of the side groove body or point-like. With the contact, the intermediate portion is farther away from the curved surface portions (103a to 105a, 103b to 105b). The gutter cover does not rattle because it is not supported at the first to third points but is supported at the corners and at the four points (line contact portions). Since the contact portion in this case shows line contact, the contact portion is excellent in the wedge effect. Furthermore, when a load is applied to the gutter cover when the vehicle travels on the gutter cover or the like, the load makes contact not only at the four corners but also on all or many contact lines. Also in this case, since line contact is made, the wedge effect is also excellent. As described above, in any case, no rattling sound is generated due to the wedge effect.

Further, the upper lid inclined surface portion 1 of the gutter lid 110
Since there is a gap G1 between 11a, 111b and the upper side frame inclined surfaces 102a, 102b of the side groove frame 101,

Line contact or surface contact on the frame lid mounting portion may be used.

As shown in FIG. 7, the gutter cover may be a gutter cover composed of a lower curved surface portion and / or an upper curved surface portion having an inclined surface portion and a concave lid groove, as shown in FIG. Thus, a gutter lid without a lid lower surface portion can be obtained.

In the case where the side groove cover is curved, FIG.
As shown in FIG. 17, since the U-shaped groove of the side groove body and the concave lid groove communicate with each other, it is possible to further increase the depression at least in the central portion caused by the curvature. as a result,
Rain water and sand accumulated in the concave lid groove can be washed out into the U-shaped groove.

The lid lower surface of the gutter cover and the frame lower surface of the gutter frame are not only a combination of vertical surfaces as shown in FIG. 2 but also both inclined surfaces as shown in FIG. Only the vertical plane and the other may be the inclined plane. Further, as shown in FIG. 26, the lid lower surface portion of the gutter lid may be configured to have a minute gap G3 with respect to the groove wall portion instead of the frame lower surface portion.

There is also no particular limitation on the vertical cross-sectional shape of the lid upper surface that is continuously extended upward from the concave lid groove. FIG.

As a result, line contact can be reliably achieved regardless of the accuracy of the mold, and rattling and noise prevention effects due to the wedge effect can be more reliably exerted. In addition, since the void has a concave groove, even if sand or the like enters the minute gap between the side groove cover and the side groove body, it is trapped in the concave groove. Furthermore, for those provided with a pair of lid lower surface portions extending downward continuously to the lower lid curved surface portion or the lower lid inclined surface portion, a minute gap is maintained between the lower surface portion and the lower surface portion of the gutter frame. And, since there is a corner at the corner of this lower surface, the wheel of the vehicle rides on the gutter lid,
Even if a load is concentrated on a part of it, the corners of the lower surface of the lid will abut against the lower surface of the opposite body,
Further bouncing can be prevented. Further, for the side groove cover and / or the side groove body provided with a curve, the line contact portions at the four corners are in line contact with the groove wall portion of the side groove, so that the side groove cover has a wedge effect and is supported at four points. No rattling. In addition, when a load is applied to the gutter lid, line contact occurs at all the expected contact line portions, so that rattling noise is not generated due to the wedge effect. Also,
In the case where this curvature is provided continuously with the concave lid groove and / or the concave skeleton groove, it is possible to prevent accumulation of rainwater in the groove portion, and to prevent sand accumulated in the concave lid groove and / or the concave skeleton groove. Can be washed into the U-shaped groove by rainwater or the like.

By using the gutters of the first to fifth inventions, the useful effects provided by the gutter structures of the sixth to sixteenth inventions can be secured.

According to the formwork of the seventeenth to twenty-first inventions, the side groove body and the side groove cover do not need to be closely adhered to each other with a large contact area between the curved surfaces. It is not necessary to form a curved surface or the like by cutting from a member such as by lathing, and it can be manufactured by bending and welding of an iron plate. Therefore, it is simple, inexpensive, and lightweight. Further, since there is a recess forming member, it is not necessary to form a shape for forming the recess in the inner mold. Therefore, regardless of the shape of the side groove body, the manufacture of the inner mold is facilitated. By using such a mold, as shown in the twenty-second to twenty-sixth inventions, it is possible to manufacture the respective side groove structures of the sixth to sixteenth inventions capable of securing the above-mentioned useful effects. it can.
