If the front cowling of the motorcycle is constructed as described in claim 1, it is not necessary to use a large number of screws or the like for fixing the windscreen, and the windscreen can be fixed with a very small number of parts. Since the fixed portion of the screen mounting member is invisible, the aesthetic appearance around the windscreen is greatly improved and the manufacturing cost is reduced.

When the front cowling of the motorcycle is constructed as described in claim 2, the shielding panel itself is also used as the screen mounting member described in claim 1. For this reason, the number of screen mounting members can be reduced accordingly, and the cushioning material between the shielding panel and the front panel can be eliminated, so that the number of parts around the windscreen can be reduced in these respects. Moreover,
Since the shielding panel is fixed to the front panel in advance, the shielding panel is fixed without distortion and deterioration of appearance is avoided,
It is not necessary to form a blackout portion for hiding the cushion material on the back side of the windscreen.

Further, when the front cowling of the motorcycle is constructed as described in claim 3, both ends of the windscreen are screwed to the front panel, so that the windscreen can be firmly fixed to the front panel, and Since the screw is exposed to the outside only at two points on both ends, there is little deterioration in appearance.

When the front cowling of the motorcycle is constructed as described in claim 4, the protrusion formed on the insertion flange is inserted into the recess formed in the insertion slit, whereby the windscreen and the front panel are separated from each other. Positioning is easy and the assemblability around the windscreen is improved.

Further, if the front cowling of the motorcycle is constructed as described in claim 5, the screen mounting member can be accurately and easily positioned at the screen mounting edge portion of the front panel by the positioning means, and in this respect also the window. The assemblability around the screen is improved.
