JP 2008-213520 A

  On the other hand, in a vehicle in which a fuel tank is arranged below the seat, since a large vehicle part is not arranged in the space between the driver's left and right feet, a flat floor is adopted, and the driver gets on and off. It was easy to configure. Also in this case, it has been desired to be able to hold the vehicle body with legs.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible for a saddle-ride type vehicle to sandwich a vehicle body with a driver's legs even when the fuel tank is disposed below the seat and the driver can easily get on and off. And

As a means for solving the above-mentioned problems, the invention described in claim 1 includes a seat (5) on which a driver is seated, a fuel tank (51) disposed below a rear portion of the seat (5), and the seat (5). A leg shield (22) formed to extend up and down in front of the seat) and left and right step floors (28L, 28R) formed to extend back and forth below the seat (5). The vehicle (1) includes a floor center cover (30) that covers the space between the left and right step floors (28L, 28R), and the floor center cover (30) has a lower end (22d) of the leg shield (22) in a side view. ), And a bulging portion (31) that forms an upper edge (30u) that slopes rearwardly upward.
The invention described in claim 2 is characterized in that the floor center cover (30) is formed to extend rearward from the front end (5f) of the seat (5).
The invention described in claim 3 is characterized in that the left and right step floors (28L, 28R) are formed so as to incline backward.
According to a fourth aspect of the present invention, the floor center cover (30) has rear extension portions (32) extending rearward on both lower sides of the seat (5), and on both lower sides of the seat (5). Is provided with a rear side cover (25) covering the upper and lower sides of the rear extension part (32), and the rear side cover (25) is an upper extension part (25a) located above the rear extension part (32). ), A storage box (50) is disposed below the seat (5) and in front of the fuel tank (51), and the upper extension part (25a) is formed in the storage box ( 50) and extending to the front.

According to the first aspect of the present invention, the floor center cover that covers the space between the left and right step floors is provided, and the bulging portion that forms the upper edge that slopes upward from the lower end of the leg shield in a side view is provided on the floor center cover. By providing, the front part of the bulging part is lowered to such an extent that it can be lightly sandwiched between both legs of the driver, and the bulging part gradually increases as the position of the leg is shifted backward. Therefore, the driver can pinch the vehicle body (the bulging portion) with legs such as a heel and a calf without greatly affecting the getting on and off of the driver. That is, when the driver straddles the vehicle body, the toe is usually lowered, so that the stride property is secured by lowering the toe side portion in the bulging portion.
According to the invention described in claim 2, even when the driver shifts the leg rearward from the front end of the seat by forming the floor center cover so as to extend rearward from the front end of the seat, The bulge can be sandwiched between legs.
According to the invention described in claim 3, by forming the left and right step floors so as to incline backward, it becomes easy to take a forward leaning posture when the driver shifts the leg to the rear of the vehicle.
According to the fourth aspect of the present invention, the rear side cover that covers the upper and lower sides of the rear extension portion of the floor center cover is provided on both lower sides of the seat, and the storage box is disposed in front of the fuel tank below the seat. By forming the upper extension portion of the rear side cover located above the rear extension portion of the cover so as to extend to the front of the storage box in a side view, the rigidity of the front portion of the storage box can be improved.

It is formed to have a sharp shape.

  The floor center cover 30 is inclined rearwardly and more steeply than the step floor 28 in a side view of FIG. 1 so that the height from the step floor 28 increases toward the rear side with respect to the lower end 22d of the leg shield 22. It is formed.

  As shown in FIG. 1, the left and right rear side covers 25 are formed so as to cover the upper and lower sides of the left and right rear extending portions 32. The left and right rear side covers 25 are located above the left and right rear extension portions 32 and have an upper extension portion 25a extending forward and upward, and located below the left and right rear extension portions 32 in a side view of FIG. And has a lower extension 25b extending forward and downward. Upper extending portions 25 a of the left and right rear side covers 25 are formed so as to extend to the front of the storage box 50 disposed below the front portion of the seat 5.

  The lower extension 25b of the left and right rear side covers 25 bulges outward in the vehicle width direction and is disposed below the rear left and right extension 32 of the floor center cover 30. Accordingly, even when the driver shifts the legs rearward and downward from the left and right rear extending portions 32 of the floor center cover 30, the lower extending portions 25b of the left and right rear side covers 25 can be sandwiched between the legs. This has the effect of improving the holdability of the vehicle body.

As described above, in the present embodiment, the seat 5 on which the driver is seated, the fuel tank 51 disposed below the rear portion of the seat 5, and the leg shield 22 formed to extend vertically in front of the seat 5. And the left and right step floors 28L, 28R formed to extend forward and backward below the seat 5, the floor center cover 30 covering the space between the left and right step floors 28L, 28R is provided. 30 includes a bulging portion 31 that forms an upper edge 30u that inclines rearwardly from the lower end 22d of the leg shield 22 in a side view of FIG.
According to this configuration, the floor center cover 30 covering the space between the left and right step floors 28L and 28R is provided, and the floor center cover 30 is provided with the upper edge 30u that inclines backward from the lower end 22d of the leg shield 22 in a side view of FIG. By providing the bulging part 31 to be formed, the front part of the bulging part 31 is lowered to such an extent that it can be lightly sandwiched between both legs of the driver, and the bulging part 31 gradually increases as the position of the leg is shifted backward. Therefore, the driver can pinch the vehicle body (the bulging portion 31) with legs such as a heel and a calf without greatly affecting the getting on and off of the driver. That is, when the driver straddles the vehicle body, the toe is usually lowered, and thus the toe side portion of the bulging portion 31 is lowered to ensure the stride property.

  Further, by extending the floor center cover 30 rearward from the front end 5f of the seat 5, the bulging portion 31 is sandwiched between the legs even when the driver shifts the leg rearward from the front end 5f of the seat 5. be able to.

  Further, by forming the left and right step floors 28L and 28R so as to incline rearward, it becomes easy to take a forward leaning posture when the driver shifts his / her leg to the rear of the vehicle.

  Further, rear side covers 25 are provided on both sides below the seat 5 so as to cover the upper and lower sides of the rear extension 32 of the floor center cover 30, and a storage box 50 is disposed below the seat 5 and in front of the fuel tank 51. The upper extension 25a of the rear side cover 25 located above the rear extension 32 is formed so as to extend to the front of the storage box 50 in a side view of FIG. 1, thereby improving the rigidity of the front part of the storage box 50. can do.

The present invention is not limited to the above-described embodiment. For example, the saddle riding type vehicle includes all vehicles on which a driver rides across a vehicle body, and includes motorcycles (motorbikes and scooter type vehicles). As well as three-wheel vehicles (including one front wheel and two rear wheels as well as two front wheels and one rear wheel vehicle) or four-wheel vehicles.
The configuration in the above embodiment is an example of the present invention, and various modifications can be made without departing from the gist of the present invention, such as replacing the component of the embodiment with a known component.
