To provide a link contrivance that can be assembled without using different components, and have different wiping range angles.
A wiping angle of a wiper driving mechanism of a front glass is decided by a pivoting range of a pivot 16, and the pivot 16 is driven by a motor 1 through a gear box 13, a crank 15, a connecting link 17, and a lever 18. The connecting link 17 can make one and more connection, and the lever can do so. Though two drivers 19 connect the connecting link 17 respectively to the crank 15 and the lever 18, the drivers are eccentrically attached. The wiping angle of the pivot 16 can be changed in a wide range by changing orientation of the drivers 19 and/or an attaching point between the connecting link 17 and the lever 18, and an attaching point between the connecting link 17 and the crank 15.
