The front unit 42 may include a light shield provided between the headlamp 44 , which is an example of a light, and the windshield 60 . Here, the front portion of the projecting edge portion 55 is a light shielding portion provided between the headlamp 44 and the windshield 60 . Since the windshield 60 is made of transparent or translucent resin or the like, light may propagate inside the windshield 60 . On the other hand, since the front unit 42, particularly the meter visor 50, blocks light, it is made of a light-blocking resin or the like. A protruding edge 55 that is part of the meter visor 50 can block light from the headlamp 44 to the windshield 60 as a light shield. Therefore, the light from the headlamp 44 is prevented from propagating through the windshield 60 and being observed by the driver.

The protruding edge as the light shielding part may be interposed between another lamp, for example, a position lamp (also called a small lamp) and the windshield 60 . The light shielding portion may be formed in a portion other than the meter visor 50, for example, another cover such as the center cowl, or may exist as a single component.

According to the fixing structure 40 for the windshield 60 in the straddle-type vehicle configured as described above, at least a part of the center portion in the width direction of the windshield 60 is covered with the center cowl 70 and fixed to the front unit 42 .

Therefore, the windshield 60 can be positioned on the front unit 42 by using the fastening and fixing force of the fastening and fixing portion 66 .

A front portion of the projecting edge portion 55 of the front unit 42 serves as a light shielding portion provided between the headlamp 44 and the windshield 60 . Therefore, light directed from the headlamp 44 toward the windshield 60 is blocked by the projecting edge portion 55 as a light blocking portion. This suppresses the driver from seeing the rear edge of the windshield 60 brightly.

The center cowl 70 also has an opposite side portion 76 , and the opposite side portion 76 is attached to the front unit 42 on the opposite side of the cover portion 72 covering the windshield 60 with the front unit 42 interposed therebetween. Therefore, the cover portion 72 of the center cowl 70 can firmly press the center cowl 70 toward the front unit 42 , and the center cowl 70 is firmly fixed to the front unit 42 .

Further, since the opening 62h is formed in the portion of the windshield 60 covered by the center cowl 70, the weight can be reduced while hiding the opening 62h from the outside.

Further, since the gate marks 60T are present in the portion of the windshield 60 covered by the center cowl 70, the gate marks 60T can be made inconspicuous.

A fixing projection 69 is formed on the windshield 60 , and a fixing recess 49 is formed on the front unit 42 . Therefore, the portion of the windshield 60 covered by the center cowl 70 is fixed to the front unit 42 without external screwing or the like.
