A wiper device equipped with a rise up mechanism, including a motor, a blade, a wiper pivot, a motor arm which rotates in one direction during the starting and wiping operations of the blade and which rotates in a reverse direction during the parking and stopping operations of the blade, a connecting rod reciprocating in response to the rotation of the motor arm to swing the wiper pivot, a retainer for retaining the connecting rod, an eccentric member for rotating together with or relative to the retainer, a friction spring disposed between the eccentric member and the retainer for permitting the rotation of the eccentric member relative to the retainer only just after the starting of the blade or just before the parking and stopping of the blade, and a cam mechanism for rotating the eccentric member together with the retainer during all operations except the operation during which the eccentric member rotates relative to the retainer just after the starting of the blade or just before the parking and stopping thereof so as to change the effective length of the connecting rod to the eccentric degree of the eccentric member. |
