Definitions
- the present invention relates to a vehicle including an inclinable body frame and two front wheels arranged side by side in the left-right direction of the body frame.
- a vehicle having a body frame that tilts in the left-right direction of the vehicle when turning left and right and two front wheels that are arranged side by side in the left-right direction of the body frame is known (see, for example, Patent Document 1).
- This type of vehicle is a vehicle that can turn with the body frame tilted with respect to the vertical direction. More specifically, the body frame tilts to the right of the vehicle when turning right, and leans to the left of the vehicle when turning left.
- the distance between two front wheels arranged side by side in the left-right direction of the body frame is very narrow compared to that of a general four-wheel vehicle. . Therefore, this type of vehicle is compact in the left-right direction of the body frame.
- the present invention reduces the size of a vehicle including a tiltable body frame and two front wheels arranged side by side in the left-right direction of the body frame, and water splashed by the two front wheels is seated on the seat.
- the purpose is to suppress the occurrence of phenomena on the legs of passengers.
- One aspect that the present invention can take in order to achieve the above object is a vehicle, A body frame that leans to the left of the vehicle when turning left and leans to the right of the vehicle when turning right; A seat supported by the body frame; A front left wheel and a front right wheel arranged side by side in the left-right direction of the vehicle body frame in front of the vehicle body frame in the front-rear direction; A steering device for rotating the left front wheel and the right front wheel; A left front fender that is rotatably provided with the left front wheel and covers at least a part of an upper surface of the left front wheel; A right front fender that is rotatably provided with the right front wheel and covers at least a part of the upper surface of the right front wheel; With The left front fender and the right front fender are arranged side by side in the left-right direction, The left front fender is An upper left wall forming an upper left inner surface facing at least a part of the upper surface of the left front wheel; A left lateral wall portion that extends downward from
- the inventors of the present application have verified in detail the mechanism of the phenomenon in which the water splashed by the two front wheels is applied to the legs of the occupant seated on the seat. As a result, the following phenomenon was confirmed.
- the adhered water falls as water droplets from the lower edge of the inner surface of the left front fender to the left of the left front wheel.
- the dropped water droplets are accelerated rearward by air flowing at a high speed toward the rear left of the left front wheel, and are applied to a leg portion of an occupant seated on a seat provided behind the left front wheel.
- the water that the right front wheel jumps up while driving is attached to the inner surface of the right front fender.
- the adhered water falls as water droplets from the lower edge of the inner surface of the right front fender to the right of the right front wheel.
- the dropped water droplets are accelerated rearward by air flowing at a high speed toward the rear right of the right front wheel, and are applied to a leg portion of an occupant sitting on a seat provided behind the right front wheel.
- the above phenomenon is caused by a vehicle having a leanable vehicle body frame and two front wheels arranged side by side in the left-right direction of the vehicle body frame. This is due to the generation of a high-speed air flow toward the rear of the direction.
- the above phenomenon is a phenomenon peculiar to a vehicle including a body frame that can be tilted and two front wheels arranged side by side in the body frame.
- the inventors examined a configuration capable of suppressing the amount of water flowing to the rear of the vehicle while reducing the size of the vehicle. Specifically, the velocity of air flowing around the vehicle during traveling was analyzed in detail. As a result, it has been found that a space where air flows slowly is formed at positions near the left side surface of the left front wheel and the right side surface of the right front wheel. And based on the knowledge obtained by this analysis, the shape of the left and right front fenders was devised, and a structure for controlling water dripped from the inner surface of the front fender was found.

- the left guide part of the left front fender has a left guide surface extending rightward in the left-right direction from the left lateral inner surface toward the left side surface of the left front wheel.
- the right guide part of the right front fender has a right guide surface extending leftward in the left-right direction from the right lateral inner surface toward the right side surface of the right front wheel. Since the left guide portion and the right guide portion are provided using the space between the left front fender and the left front wheel and between the right front fender and the right front wheel, the vehicle can be reduced in size.
- the size of the vehicle including the body frame that can be tilted and the two front wheels arranged side by side in the left-right direction of the body frame is reduced, and the water splashed by the two front wheels is seated on the seat of the passenger Occurrence of a phenomenon related to a part or the like can be suppressed.
- At least a part of the left guide part may be provided at a lower part of the left lateral wall part, and at least a part of the right guide part may be provided at a lower part of the right lateral wall part.
- water can be dropped from the left guide portion and the right guide portion at a lower position.
- the size of the vehicle including the body frame that can be tilted and the two front wheels arranged side by side in the left-right direction of the body frame is reduced, and the water splashed by the two front wheels is seated on the seat of the passenger Occurrence of a phenomenon related to a part can be further suppressed.
- Each of the left guide portion and the right guide portion may have a portion extending in the front-rear direction.

It is good also as a structure which has a shape.
- the water splashed up by the left front wheel is prevented from splashing backward by the left lateral wall part and the left guide part provided to the left of the left side surface of the left front wheel. Since the necessity to provide a similar structure on the right side of the right side surface of the left front wheel is reduced, the degree of design freedom for downsizing can be increased with respect to the shape of the left front fender at that location. Similarly, the water splashed up by the right front wheel is prevented from splashing backward by the right lateral wall portion and the right guide portion provided to the right of the right side surface of the right front wheel.
- the degree of design freedom for miniaturization can be increased with respect to the shape of the right front fender at that location. Therefore, while further downsizing a vehicle including a leanable vehicle body frame and two front wheels arranged side by side in the left-right direction of the vehicle body, the water splashed by the two front wheels of the occupant seated on the seat Occurrence of a phenomenon related to the leg can be suppressed.
