Abstract
In an opposite arrangement-type wiper system, an operation range 5b of an assistant driver's seat-side wiper blade 1b is set in such a way as to be narrower than an operation range 5a of a driver's seat-side wiper blade 1a and to overlap with the operation range 5a only partially. A lower side turn point Lb of the wiper blade 1b is set near an outer periphery R of the operation range 5a and an overlapping operation range 6c is formed between the operation ranges 5a and 5b. A normal stop position of the wiper blade 1b at the time when the wiper system is not running is set on the side of an upper side turn point Ub. While being arranged opposite from each other, the wiper blades 1a and 1b operate in tandem in the same direction when moving back and forth for wiping.

A wiper system of an opposite arrangement type, comprising:
- wiper blades that are disposed on a to-be-wiped surface of a vehicle in such a way as to face each other and are designed to conduct a wiping operation back and forth between lower side turn points and upper side turn points that are set on the to-be-wiped surface;
- and
- electric motors that enable the wiper blades to move back and forth on the to-be-wiped surface, wherein
- the wiper blades comprise a first wiper blade, which is disposed at driver's seat side, and a second wiper blade, which is disposed at assistant driver's seat side,
- an operation range of the second wiper blade on the to-be-wiped surface is narrower than an operation range of the first wiper blade and is set in such a way as to only partially overlap with the operation range of the first wiper blade, and
- the first wiper blade and the second wiper blade move in the same direction when moving back and forth for wiping.
