ABSTRACT:
A wiper linkage of the cross arm type is provided with a driving rod, an oscillation arm, two cross arms interlinking the driving rod and the oscillation arm, and restrictive alignment-free couplings connecting the cross arms between the driving rod and oscillation arm. In this linkage, it is possible to connect the coupling parts easily and to absorb dimensional errors in the coupling parts, and to also make the coupling waterproof by a sealing member. Furthermore, a smooth and noiseless action of the linkage can be obtained.
