(Summary of the first embodiment)
In the vehicle body side structure of the vehicle 10 of the present embodiment, a shutter door 26 that closes the entrance/exit 25 on the side of the vehicle and opens toward the upper side of the vehicle is provided. The shutter door 26 is not opened in the longitudinal direction of the vehicle where the steered wheels are located. Specifically, the front shutter door 26F does not slide open toward the front wheel 24A, which is the steering wheel.

Here, as shown in FIG. 5, in the vehicle 100 of the comparative example, when the slide door 126 is installed in the entrance/exit 25 provided between the rear end of the front wheel 24A and the front end of the rear wheel 24B. assume. Assuming that the width of the sliding door 126 (the length in the longitudinal direction of the vehicle) is A, and the distance in the longitudinal direction of the vehicle from the front wheels 24A to the sliding door 126 is B, the sliding door 126 is opened toward the front wheels 24A, which are steering wheels. In this case, it is desirable that the distance B is equal to or greater than the width A. That is, in the vehicle 100 of the comparative example, unless the slide door 126 is displaced outward in the vehicle width direction from the steered front wheels 24A, the fully opened slide door 126 interferes with the front wheels 24A.

In the comparative example, although there is room to prevent interference with the front wheels 24A by opening the slide door 126 toward the rear side of the vehicle, the vehicle 10 of the present embodiment also has the entrance/exit 25 on the rear side of the vehicle. , the front wheel 24A must be slid. Further, when the width A of the sliding door 126 is larger than half of the distance T between the rear end of the front wheel 24A and the front end of the rear wheel 24B, the sliding door 126 cannot be slid toward the front wheel 24A if there is a restriction that prevents it from sliding toward the rear wheel 24B. I can't help it. In this case, it is necessary to set the width A of the sliding door 126 narrower than the distance B from the front wheel 24A to the sliding door 126 in the longitudinal direction of the vehicle. Thus, in the comparative example, if the front wheels 24A are not oriented straight ahead, there is a risk of interference between the slide door 126 and the front wheels 24A.

Also, although not shown, in the case of a gull-wing type door, interference with the front wheels 24A can be avoided, but in this case, a space for deploying the door is required outside the door in the vehicle width direction. Here, the space is required as the height of the door (the length in the vertical direction of the vehicle) increases. In other words, the gull-wing type door that closes the entrance/exit 25 through which an adult passenger can walk to get in and out of the vehicle, as in the present embodiment, requires a large space on the outside in the vehicle width direction.

On the other hand, in the present embodiment, by providing the shutter door 26 that opens toward the upper side of the vehicle, the width A of the slide door 126 and the distance from the front wheels 24A to the slide door 126 are reduced as in the slide door 126 of the comparative example. No need to set B. That is, according to the present embodiment, the width of the shutter door 26 (length in the longitudinal direction of the vehicle) can be increased. Moreover, since the shutter door 26 of this embodiment does not slide toward the front wheels 24A, it naturally does not interfere with the front wheels 24A, which are the steering wheels. Further, unlike a gull-wing type door, it does not require a space for deploying the door outside in the vehicle width direction. Therefore, the door can be opened even in a narrow space around the vehicle 10.例文帳に追加

In addition, the vehicle body side structure of the present embodiment includes the environment sensor 44 at a location separate from the shutter door 26 in the longitudinal direction of the vehicle. Specifically, a side sensor 44B is provided on the vehicle front side of the front shutter door 26F, and a side sensor 44C is provided on the vehicle rear side of the rear shutter door 26R. According to this embodiment, the environment sensor 44 is not blocked when the shutter door 26 is opened and closed, and the surrounding conditions can be grasped. Therefore, while the vehicle 10 is stopped and the shutter door 26 is open, the surrounding conditions can be grasped, and the vehicle 10 can be started smoothly.

Further, in the vehicle body structure of the present embodiment, the shutter rail 50 for guiding the shutter door 26 is provided for the roof cross member 64 . That is, according to the present embodiment, the structure of the roof 20B can be used to dispose the shutter door 26, and the complexity of the structure of the roof 20B can be suppressed. Although the shutter rails 50 are fixed to the pillars 60 and the roof cross member 64 in this embodiment, the shutter rails 50 may be formed by the pillars 60 and the roof cross member 64 themselves. In this case, an increase in the number of parts when providing the shutter door 26 can be further suppressed.

Further, in the vehicle body side structure of the present embodiment, the display device 54 is provided on the outside of the shutter door 26 in the vehicle width direction, that is, on the outside of the vehicle. According to this embodiment, the display device 54 corresponding to the wide shutter door 26 can enhance the advertising effect when the vehicle 10 is running. The display device 54 may be provided inside the shutter door 26 in the vehicle width direction, that is, on the vehicle interior 20 side. For example, when the vehicle 10 is used to deliver packages, the display device 54 can display information such as delivery destinations, delivery items, delivery order, and the like. In other words, it is possible to provide necessary information to the person in charge of delivery and the recipient of the parcel. Further, for example, when the vehicle 10 is used to move passengers, the display device 54 can display destination guidance and advertisements. In other words, necessary information can be provided to passengers and advertisements can be made.
