The invention provides a windshield controller for a motorcycle that can appropriately change the height of a windscreen at the time of parking or the like even without the provision of a windscreen operating switch or of a parking operation detecting component. A control section (CPU 220) which controllably drives a movable windscreen disposed on a front fairing for the front portion of a vehicle body judges whether or not a portable communication device (210) is away from the vehicle body on the basis of a signal received by a receiver section (225), and if it is judged that the portable communication device (210) is away from the vehicle body, a screen drive section (280) drives an electric motor to move the windscreen to a standby position.
