ABSTRACT:
In a wiper of the present invention of a telescopic construction, a wiper arm is divided into two, namely, upper and lower arm parts. The upper arm is arranged to be slid in relation to the lower arm which is a housing for the upper arm. In the above construction, since the upper arm is driven by a compact double mechanism which comprises a crank, a pinion and a pair of racks, the upper arm can be slid by large degrees without requiring a large space. Therefore, the wiping area is advantageously enlarged according to the present invention.
