Abstract

A straddle-type vehicle comprises a radiator through which air flowing from a front flows in a forward and rearward direction of a vehicle body; an engine which generates driving power for allowing the straddle-type vehicle to travel, the engine being disposed rearward of the radiator; and a cover unit covering from above a space formed between the radiator and the engine, and the engine, wherein the cover unit includes: a hard cover which is located at a front side of the cover unit, extends rearward from the radiator, and covers the space formed between the radiator and the engine; and a soft cover which is located at a rear side of the cover unit, extends rearward from the hard cover, and covers the engine.

First claim

The invention claimed is:

1. A straddle vehicle comprising:
a radiator through which air flowing from a front flows in a forward and rearward direction of a vehicle body;
an engine which generates driving power for allowing the straddle vehicle to travel, the engine being disposed rearward of the radiator; and
a cover unit covering from above a space formed between the radiator and the engine, and the engine,
wherein the cover unit includes:
a hard cover which is located at a front side of the cover unit, extends rearward from the radiator, and covers the space formed between the radiator and the engine; and
a soft cover which is located at a rear side of the cover unit, extends rearward from the hard cover, and covers the engine.

2. The straddle vehicle according to claim 1 , further comprising:
a fan which is disposed in such a manner that an axial direction of a rotary shaft of the fan conforms to the forward and rearward direction, and forcibly flows the air through the radiator,
wherein the hard cover includes a side wall extending in a vertical direction, on at least a first side in a vehicle width direction of the vehicle body.

3. The straddle vehicle according to claim 2 ,
wherein the first side in the vehicle width direction is a side where the fan is rotatable in a downward direction in a front view, of both sides in the vehicle width direction, and
wherein a lower end portion of at least a portion of the side wall of the hard cover is located above the rotary shaft of the fan.

4. The straddle vehicle according to claim 2 ,
wherein the hard cover further includes a body extending rearward from the radiator, and a rear wall extending in the vehicle width direction and in the vertical direction, from the body, and
wherein a lower end portion of the rear wall of the hard cover is located above a center of the radiator in the vertical direction.

5. The straddle vehicle according to claim 2 ,
wherein the hard cover further includes a guide side wall which is located on a second side in the vehicle width direction, is curved along a circumferential direction of the fan, and guides the air along the circumferential direction of the fan, in a front view.

6. The straddle vehicle according to claim 1 ,
wherein the radiator includes an inlet which is disposed on a third side in a direction perpendicular to the forward and rearward direction and through which a coolant which has cooled the engine flows into the radiator, and
wherein in a front view, a center of the hard cover in the direction perpendicular to the forward and rearward direction is located on a fourth side in the direction perpendicular to the forward and rearward direction, relative to a center of the radiator in the direction perpendicular to the forward and rearward direction.

7. The straddle vehicle according to claim 1 , further comprising:
a retaining member which is provided at the hard cover and secures a harness disposed inside the vehicle body to the hard cover.

8. The straddle vehicle according to claim 1 , further comprising:
a regulator which controls a voltage value of electric power output from a power generator which generates electric power by the driving power generated by the engine,
wherein when viewed from above, the regulator is disposed at a location that overlaps with the hard cover.

9. The straddle vehicle according to claim 1 ,
wherein the soft cover covers a head cover of the engine, and is engaged with a portion of the engine which is rearward of the head cover.

10. The straddle vehicle according to claim 1 ,
wherein at least one of an electric component of the engine and an engine component included in the engine is provided at the engine and protrudes upward from the engine, and at least one air-intake system member is connected to the engine,
wherein the soft cover includes an opening into which at least one of the electric component and the engine component is inserted, and is connected to a rear portion or an upper portion of the hard cover, and
wherein a rear portion of the soft cover is retained by a connection section of the engine which is connected to the at least one air-intake system member.

11. The straddle vehicle according to claim 1 ,
wherein when viewed from above, a dimension in a vehicle width direction of the soft cover is set smaller than a dimension in the vehicle width direction of a cylinder head of the engine.

12. The straddle vehicle according to claim 1 ,
wherein the soft cover is disposed inward relative to both sides of the radiator in a vehicle width direction, and
wherein when viewed from above, a dimension in the vehicle width direction of the soft cover is set smaller than a dimension in the vehicle width direction of a cylinder head of the engine.

13. The straddle vehicle according to claim 1 ,
wherein the hard cover includes a plurality of engagement portions which are arranged side by side in a vehicle width direction and have tip end portions extending downward, and
wherein each of the plurality of engagement portions extends forward and is engaged with an upper end portion of the radiator.
