Further, the first bent portion 141 is inclined in the vehicle front-rear direction away from the connector portion 222 of the retractor 22 and downward in the vehicle. As a result, the first bent portion 141 forms a gutter that adheres to the main surface 13A of the upper pillar garnish 13 and allows water droplets entering from the belt outlet 10A to flow down. The direction in which the water droplets flow down the first bent portion 141 is the direction away from the connector portion 222 . At the same time, water droplets adhering to the rear surface 13B of the upper pillar garnish 13 flow down to the second bent portion 142, and the Coanda effect acts on the water droplets. Therefore, the water droplets are attracted to the lower edge 14A of the water guide portion 14. As shown in FIG. Therefore, according to the water guide portion 14 having this configuration, the water droplets that have flowed down to the water guide portion 14 can be more effectively guided to the belt belt 21 . Furthermore, according to the water guide portion 14 having this configuration, the effect of suppressing water droplets dripping onto the connector portion 222 can be particularly improved. In addition, in the storage structure A11, the Coanda effect acts on water droplets that flow down to the first bent portion 141, and the second bent portion 142 forms a gutter.

A lower edge 14A of the water guide portion 14 has a sharp shape when viewed along the vehicle width direction. The first bent portion 141 and the second bent portion 142 are connected to the lower edge 14A. The first bent portion 141 forms a concave curved surface with a radius of curvature r1 (centered at point O1). The second bent portion 142 forms a convex curved surface with a radius of curvature r2 (centered at point O2). Accordingly, the Coanda effect acts on the water droplets that have flowed down to the first bent portion 141 and the water droplets that have flowed down to the second bent portion 142 . These water droplets are therefore attracted to the lower edge 14A. Furthermore, the radius of curvature r2 is greater than the radius of curvature r1. As a result, it is possible to suppress the water droplets that have flowed down to the first bent portion 141 from reaching the second bent portion 142 across the lower edge 14A due to the Coanda effect. Furthermore, since the water guide portion 14 is bent toward the belt belt 21 , water droplets attracted to the lower edge 14</b>A can be effectively guided to the belt belt 21 .

[Third Embodiment]
A seat belt storage structure A30 (hereinafter referred to as "storage structure A30") according to the third embodiment of the present invention will be described with reference to FIG. In this figure, the same reference numerals are given to the elements that are the same as or similar to those of the storage structure A10 described above, and overlapping descriptions are omitted. The cross-sectional position of FIG. 6 is the same as the cross-sectional position of FIG.

In the storage structure A30, the configuration of the water guide portion 14 is different from the configuration of the storage structure A10 described above. The main purpose of the water guide part 14 of the storage structure A30 is to guide water droplets adhering to the main surface 13A of the upper pillar garnish 13 among the water droplets that have entered the storage space for the seat belt 20 provided in the vehicle side member 10. and

The water guide surface 143 is a curved surface that bulges inward of the vehicle in the vehicle width direction. The groove portion 144 is connected to the lower end of the water guiding surface 143 and extends in the direction indicated by the arrow in FIG. The groove portion 144 is recessed in the vehicle width direction from the main surface 13</b>A and faces the belt belt 21 . The direction in which the groove portion 144 is recessed is opposite to the direction in which the water guiding surface 143 protrudes in the vehicle width direction. The groove portion 144 forms a gutter. In the storage structure A30, the cross-sectional shape of the groove 144 in the direction perpendicular to the direction in which the groove 144 extends is V-shaped. The cross-sectional shape may be rectangular, for example. The lower edge 14A is included in the groove portion 144. As shown in FIG.

Next, the effects of the storage structure A30 will be described.

In the storage structure A30, the vehicle side member 10 (upper pillar garnish 13) is provided with a water guide portion 14 positioned below the vehicle from the belt outlet 10A. The water guide portion 14 is positioned further outward of the vehicle in the vehicle width direction than the belt belt 21 and extends continuously in the vehicle front-rear direction. Furthermore, at least a portion of the belt band 21 overlaps the water guide portion 14 when viewed along the vehicle width direction. Therefore, the storage structure A30 can also prevent water droplets that have entered the storage space for the seat belt 20 provided in the vehicle side member 10 from dripping onto the retractor 22 or the like.

In the housing structure A30 , the water guide portion 14 has a water guide surface 143 and grooves 144 . Water droplets adhering to the main surface 13A of the upper pillar garnish 13 flow down to the water conveying portion 14 along the water conveying surface 143 . The water guide surface 143 is a curved surface that bulges inward of the vehicle in the vehicle width direction. As a result, the Coanda effect acts on the water droplets traveling along the water guide surface 143 , so that more water droplets can flow down to the groove portion 144 while suppressing the separation of the water droplets from the water guide surface 143 . Furthermore, surface tension acts on the water droplets that have flowed down into the grooves 144 . Accordingly, the groove portion 144 can hold the water droplets and allow the water droplets to flow down toward the end of the water guide portion 14 (the vehicle rear end of the water guide portion 14 in the storage structure A30). Therefore, according to the housing structure A30, it is possible to reduce the number of water droplets guided from the lower edge 14A of the water guide portion 14 to the belt belt 21 while allowing more water droplets to flow down to a position away from the retractor 22 and the like.

The main purpose is to conduct water droplets adhering to the

As shown in FIGS. 7 and 8, the groove portion 144 includes a first groove portion 144A and a second groove portion 144B. The first groove portion 144A is connected to the lower end of the water guiding surface 143. As shown in FIG. The second groove portion 144B is positioned below the vehicle relative to the first groove portion 144A. The upper end of the second groove portion 144B is connected to the lower end of the first groove portion 144A via a ridge portion 144C shown in FIG. Each of the first groove portion 144A and the second groove portion 144B together form a gutter. The cross-sectional shape of each of the first groove portion 144A and the second groove portion 144B in the direction orthogonal to the direction in which the groove portion 144 extends is both V-shaped. The cross-sectional shape of each of the first groove portion 144A and the second groove portion 144B may be rectangular, for example. When the cross-sectional shapes of the first groove portion 144A and the second groove portion 144B are both V-shaped, the opening angle α1 of the first groove portion 144A shown in FIG. 9 is less than the opening angle α2 of the second groove portion 144B shown in FIG. is also large.

As shown in FIG. 9, an extended portion 145 is provided in the second groove portion 144B. The extended portion 145 is a portion extending toward the inside of the upper pillar garnish 13 from the surface of the upper pillar garnish 13 that defines the second groove portion 144B. This enlarges the area of the surface. The extension portion 145 may also be provided in the first groove portion 144A.

As shown in FIG. 9, the second groove portion 144B has an overhang d. The protrusion d protrudes inward of the vehicle in the vehicle width direction from the ridge 144C.

Next, the effects of the storage structure A40 will be described.

In the storage structure A40, the vehicle side member 10 (upper pillar garnish 13) is provided with a water guide portion 14 positioned below the vehicle from the belt outlet 10A. The water guide portion 14 is positioned further outward of the vehicle in the vehicle width direction than the belt belt 21 and extends continuously in the vehicle front-rear direction. Furthermore, at least a portion of the belt band 21 overlaps the water guide portion 14 when viewed along the vehicle width direction. Therefore, the storage structure A40 can also prevent water droplets that have entered the storage space for the seat belt 20 provided in the vehicle side member 10 from dripping onto the retractor 22 or the like.

In the storage structure A40, the water guide portion 14 includes a first groove portion 144A and a second groove portion 144B. Surface tension acts on water droplets that have flowed down the first groove portion 144A along the water guiding surface 143 . As a result, the first groove portion 144A can hold the water droplets and allow the water droplets to flow down toward the end of the water guide portion 14 (the vehicle rear end of the water guide portion 14 in the storage structure A40). Further, water droplets overflowing from the first groove portion 144A toward the vehicle downward direction flow down along the ridge portion 144C shown in FIG. 9 to the second groove portion 144B. Surface tension also acts on water droplets that have flowed down into the second groove portion 144B. As a result, the second groove portion 144</b>B can also hold the water droplets and allow the water droplets to flow down toward the flow end of the water guide portion 14 . Therefore, according to the storage structure A40, more water droplets than the storage structure A30 flow down to a position away from the retractor 22, and the water droplets guided from the lower edge 14A of the water guide portion 14 to the belt belt 21 are stored. It can be further reduced than structure A30.

An extension portion 145 is provided in the second groove portion 144B. As a result, in addition to the surface tension acting on the water droplets that have flowed down into the second groove portion 144B, capillary action appears. This increases the force of the second groove portion 144B to hold the water droplets, so that the water droplets guided from the lower edge 14A of the water guide portion 14 to the belt belt 21 can be more effectively reduced.

The second groove portion 144B has an overhang d. As a result, water droplets overflowing downward from the first groove portion 144A can be more reliably received by the protrusion d.

In the storage structures A10 to A40, the interior member covering the center pillar 11 is composed of two members, the lower pillar garnish 12 and the upper pillar garnish 13, but they may be integrated into a single member. .
