Utility vehicle

1. A utility vehicle comprising:

a main frame;

a bottom plate below the main frame and attached to the main frame; and

a slide member attached to a lower surface of the bottom plate;

wherein the main frame includes a pair of left and right center frames extending obliquely outward in a vehicle width direction from a vicinity of a front end of a seat of the utility vehicle toward a vicinity of a rear end of the seat, and

wherein the slide member includes:

a pair of left and right main members extending obliquely outward in a vehicle width direction from a vicinity of a front end of a seat of the utility vehicle toward a vicinity of a rear end of the seat, and

a pair of outer members positioned outwardly of the pair of left and right main members with respect to the vehicle width direction, the pair of outer members extending rearward in parallel with a longitudinal axis of a vehicle body of the utility vehicle.

2. The utility vehicle of claim 1 , wherein the slide member is made of plastic.

3. The utility vehicle of claim 1 , wherein each of the pair of left and right main members and each of the pair of outer members has:

chamfered bottom outer edges with respect to the vehicle width direction, the chamfered bottom outer edges extending in parallel to a longitudinal axis of a corresponding one of the pair of left and right center frames, and

inclined outer surfaces with respect to the vehicle width direction, the outer surfaces being inclined inwardly from an upper surface to a lower surface.

4. The utility vehicle of claim 1 , wherein each of the pair of left and right main members and each of the pair of outer members has a recess extending along a longitudinal axis thereof, the recess having a width in a direction orthogonal to the longitudinal axis.

5. The utility vehicle of claim 4 , wherein the recess is located at a center with respect to a width of each respective one of the pair of left and right main members and the pair of outer members, and a width of the recess is less than a width of each of side portions of the recess extending along the recess.

6. The utility vehicle of claim 1 , wherein each of the pair of left and right main members and each of the pair of outer members has a uniform cross-sectional shape along a longitudinal axis thereof.

7. The utility vehicle of claim 1 , wherein the slide member is located between outer edges of a vehicle body of the utility vehicle.

8. The utility vehicle of claim 7 , wherein the main frame is located between the outer edges of the vehicle body, and the slide member is located below and along the main frame.

9. The utility vehicle of claim 1 , wherein the pair of left and right main members extend along the pair of left and right center frames on opposite sides of the bottom plate.

10. The utility vehicle of claim 1 , wherein the slide member is positioned in the middle in a vehicle width direction of the pair of left and right main members, and the slide member includes an intermediate member extending rearward in parallel with a front-rear direction of the vehicle body.

11. The utility vehicle of claim 10 , wherein a front end position of each of the main members and a front end position of the intermediate member are aligned with respect to the front-rear direction of the vehicle body, and a rear end position of each of the main members and a rear end position of the intermediate member are aligned with respect to the front-rear direction of the vehicle body, and

a width of each of the main members and a width of the intermediate member are equal.

12. The utility vehicle of claim 7 , wherein the slide member has an outer edge and an outer surface with respect to the vehicle width direction, a bottom surface of the outer edge being chamfered, and the outer surface being inclined inwardly with respect to the vehicle width direction from an upper surface toward the bottom surface.
