PURPOSE:To simplify the driving structure of a wiper by making the actuation speed of the wiper variable responding to the travelling speed of a vehicle in a wiper device of a wind shield mounted on the handle part of a motor cycle. CONSTITUTION:When a wiper 17 is attached on a wind shield 2 mounted on the handle 1 part of a motorcycle, this wiper 17 is actuated for wiping by a wiper unit 3 connected to and driven by an engine assembly 20. Namely, a worm 22 is formed on the prescribed position of a final shaft 21 of transmission in the assembly 20, and a pick-up shaft 24 provided with a worm wheel 25 engaging with said worm 22 in an appropriate reduction ratio on the top of said wheel is rotatably supported on an assembly case 23. And a crank 26 is fixed, on the end part of the shaft 24 and one end of a driving cable 31 for transmitting power to the wiper unit 3 is connected its free end. |
