A synthetic resin windscreen for motorcycles, motor tricycles, etc. comprises a fitting edge portion which is fixed to the body of a motorcycle or a motor tricycle, a screen surface main portion, and a screen surface peripheral edge portion, which are all integrally formed in one piece by means of injection molding, for instance. The above three portions have different thicknesses from each other, which are individually sufficient for ensuring respective required values of mechanical strength. At least part of the screen surface main portion is smaller in thickness than the fitting edge portion. Preferably, the screen surface main portion has its thickness gradually decreasing from a location adjacent the fitting edge portion to a location adjacent the screen surface peripheral edge portion.
