Claim:
A wiper system comprising: first and second wiper arms; and first and second wiper blades that are connected to the first and second wiper arms, respectively, to wipe a wiping surface, wherein the first wiper arm includes a cover portion, which at least partially covers at least one of the second wiper arm and the second wiper blade to continuously arrange the first and the second wiper arms one after the other along a lower edge of the wiping surface when each of the first and second wiper blades is placed in a corresponding stop position thereof, wherein the first and second wiper arms are respectively swung from the stop position of the corresponding wiper blade in a common direction, the cover portion of the first wiper arm forms a distal end portion of the first wiper arm, which is overlapped with a base end portion of the second wiper arm in a height direction of the cover portion of the first wiper arm to form an overlapped section when each of the first and second wiper blades is placed in the corresponding stop position, the overlapped section is configured such that a top surface of the first wiper arm is generally flush with a top surface of the second wiper arm in the overlapped section when each of the first and second wiper blades is placed in the corresponding stop position, the first and second wiper arms have opposed surfaces, respectively, which are opposed to each other in the longitudinal direction and are tilted relative to the longitudinal direction of each of the first and second wiper arms when each of the first and second wiper blades is placed in the corresponding stop position, the opposed surface of the first wiper arm has an undercut shape, which is undercut in a wiping movement start direction of each of the first and second wiper arms, and the opposed surface of the second wiper arm has an uppercut shape, which is uppercut in the wiping movement start direction of each of the first and second wiper arms.
