御装置。(2) Control the irradiation direction of a headlight that consists of a reflector fixed to the front of the motorcycle, a lens that covers the front of the reflector, and a light bulb disposed between the reflector and the lens. In the headlight irradiation direction control device for motorcycles, the light bulb is placed between the reflector and the lens so that it can be rotated in the left and right directions, and the support section attached to the front fork has a headlight that can be rotated in the forward and reverse directions. A drive motor and a drive mechanism connecting the drive motor and the light bulb to convert the forward/reverse motion of the drive motor into left/right rotation of the light bulb are provided, and the drive mechanism connects the drive motor and the light bulb to rotate the light bulb when turning based on the vehicle speed and steering angle. A control circuit that calculates the radius and outputs an operation control value for changing the irradiation direction according to the calculated value is connected to the drive motor, and a vehicle speed detector and a steering angle detector are connected to the control circuit. A headlight irradiation direction control device for a motorcycle, characterized by the following.
