PURPOSE: A wiper system for guiding bending is provided to prevent pedestrian injury against the wiper arm and the pivot shaft in bumping the pedestrian into the windshield glass of a vehicle, and to operate the wiper system actively by lifting up and down the pivot connecting part. CONSTITUTION: A wiper system is composed of a wiper arm(1) and a housing(2), and a first pivot shaft(10) and a second pivot shaft(20) are formed between the wiper arm and the housing with the double structure to transmit driving force of a motor to the wiper arm. The first pivot shaft is composed of a flexible shaft part(11) made of rubber to fit the second pivot shaft, and a shaft recessed part(12) guiding depression of the second pivot in reaching the critical impact point of the flexible shaft part in bumping a pedestrian into the windshield of a vehicle. A fitting groove(21) is formed in the second pivot shaft and inserted to the flexible shaft part.
