That is, the upper end portion 201 of the vehicle body and the inclined portion 202 of the vehicle body are always visible to the outside of the vehicle regardless of whether the door 100 is opened or closed, and are exposed from the outside of the vehicle when the door 100 is open but the door 100 is closed. It has an unexposed surface (a surface recessed toward the passenger compartment with respect to the exposed surface). The bellows upper portion 37 of the bellows portion 31 is provided so as to be sandwiched between the inner surface of the door upper end portion 102c (the surface facing the vehicle body side) and the unexposed surface of the vehicle body upper end portion 201. The bellows inclined portion 36 and the water receiving portion 32 of the bellows portion 31 are provided so as to be sandwiched between the inner surface of the door inclined portion 102d and the unexposed surface of the vehicle body inclined portion 202. At this time, one end of the bellows portion 31 in the deployment direction is attached directly to the inner surface of the door upper end portion 102c and the door inclined portion 102d or indirectly via an attachment member, and the other end portion is attached. It is attached directly to the non-exposed surfaces of the vehicle body upper end portion 201 and the vehicle body inclined portion 202 or indirectly via a mounting member. The bellows portion 31 can be attached to the door 100 and the vehicle body by any method such as hooking by a claw portion.

The above is the configuration of the rainproof device 1. Next, the action and effect of the rainproof device 1 will be described. When the door 100 is opened, the bellows type cover 30 is deployed on the front end side of the door 100 by widening the distance between the mountain fold portions 33a and 34a and the valley fold portions 33b and 34b, and the rear end side of the door 100 is wound up. The curtain 3 of the formula curtain unit 2 unfolds (see FIG. 1). As a result, it is possible to prevent rain from entering the space formed between the door 100 and the front seat entrance / exit, and it is possible to prevent the occupants from getting wet when getting on / off the vehicle. Further, when the door 100 is closed, the distance between the mountain fold portions 33a and 34a and the valley fold portions 33b and 34b is shortened, so that the bellows type cover 30 is folded and the curtain 3 is wound around the take-up shaft 5.

Further, since the rear end portion 3d of the curtain 3 is formed in a straight line, it is possible to prevent the rear end portion 3d from hanging down when the curtain 3 is unfolded. As a result, it is possible to prevent the rain incident on the curtain 3 from flowing backward and hitting the occupants.

Further, since the take-up shaft 5 of the take-up type curtain portion 2 is provided in a forward tilted state with respect to the horizontal line, it is possible to give the curtain 3 at the time of deployment a gradient that becomes lower toward the front. As a result, it is possible to prevent the rain incident on the curtain 3 from flowing backward and hitting the occupants.

Further, since the bellows type cover 30 is provided on the inclined portions 102d and 202, which is difficult to provide the retractable curtain portion 2, it is possible to prevent rain from entering from the inclined portions 102d and 202.

Further, since the bellows type cover 30 is provided only in front of the door 100, the length in the deployment direction on the rear end side of the bellows type cover 30 can be shortened as compared with the case where the bellows type cover 30 is provided on the entire door 100. As a result, it is possible to prevent the rear end side of the bellows type cover 30 from hanging down due to its own weight. Further, as compared with the case where the bellows type cover 30 is provided on the entire door 100, the number of bellows can be reduced by the amount that the length in the deployment direction on the rear end side can be shortened. As a result, it is possible to prevent the door 100 from becoming difficult to close due to the bellows type cover 30.

Further, there may be no space for sandwiching the bellows type cover 30 around the door rotation axis L1, but the front portion 34 of the bellows type cover 30 provided around the door rotation axis L1 is bellows as compared with the rear portion 33. Since the number of sheets is small, it is possible to prevent the door 100 from becoming difficult to close. The distance between the door 100 and the vehicle body when the door 100 is opened at the position where the bellows front portion 34 is provided is compared with the distance between the door 100 and the vehicle body when the door 100 is opened at the position where the bellows rear portion 33 is provided. Since it is narrow, even if the number of bellows in the bellows front portion 34 is reduced, there is no problem that the bellows front portion 34 becomes difficult to deploy.

Conversely, since the bellows rear portion 33 has a larger number of bellows than the bellows front portion 34, it is possible to prevent the bellows rear portion 33 from becoming difficult to open. Further, if the number of bellows is too small, the angle of the mountain fold portion and the valley fold portion becomes large when opened, and if the angle is too large, the rear end side hangs down due to its own weight. In this respect, since the bellows rear portion 33 has a larger number of bellows than the bellows front portion 34, it is possible to prevent the rear end side from hanging due to its own weight.

Further, since the number of bellows of the bellows type cover 30 is gradually reduced by the diagonal portion 35 (see FIG. 6), the appearance at the time of deployment can be improved and the bellows type can be improved as compared with the case where the number of bellows is suddenly reduced. It is possible to prevent a sudden change in rigidity between the front and the rear of the cover 30. As a result, it is possible to prevent twisting and sagging during deployment.

Further, as shown in FIG. 6, since the mountain fold portion 33d having the diagonal portion 35 and the mountain fold portion 33c having no diagonal portion 35 are alternately provided, the number of bellows in the bellows front portion 34 can be set to the bellows rear portion. The number of bellows in the portion 33 can be halved. As a result, the bellows front portion 34 can be easily installed in a narrow space close to the door rotation axis L1. In addition, the appearance at the time of deployment can be improved, and the bias of the rigidity can be suppressed at the boundary position between the bellows rear portion 33 and the front portion 34. As a result, it is possible to prevent twisting and sagging during deployment.

Further, since the valley fold portion 37a (see FIG. 7) on the rear end side of the bellows type cover 30 is given a gradient that tilts forward with respect to the horizon, the rain incident on the bellows type cover 30 flows backward. It is possible to prevent the occupant from getting caught.

Further, since the bellows type cover 30 has the water receiving portion 32 at the tip, it is possible to prevent the rain incident on the bellows portion 31 from falling down while being dispersed over a wide range.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the description of the scope of claims. For example, in the above embodiment, in the take-up curtain portion, an example in which the take-up mechanism is attached to the vehicle body side has been described, but the take-up mechanism may be provided on the door side.

Further, in the above embodiment, the number of bellows in the front portion of the bellows type cover is set to half of the number of bellows in the rear portion, but the number may be reduced by any other number. In other words, in the above embodiment, every other mountain fold portion of the bellows portion is connected to the front valley fold portion, but every other mountain fold portion may be connected to the front valley fold portion.

If there is enough space to install the bellows cover, the bellows cover does not reduce the number of bellows on the front side (that is, the number of bellows on the rear side and the number of bellows on the front side are the same). May be used.

Further, in the above embodiment, an example in which the rainproof device is attached to the front seat door of the vehicle is shown, but a door having the same shape as the front seat door (that is, a shape having an inclined portion from the front end of the upper end portion) is provided. It may be attached to other provided objects (moving objects other than vehicles (vehicles in amusement parks, ships, etc.) or objects other than moving objects).
