Abstract
A wiper device is provided with a wiper arm including an arm head, a retainer and a coil spring, and with a lock-back detecting device which detects whether or not the wiper arm is in a 'lock-back' state and shuts off a power supply to the motor in case of detecting the wiper arm to be in the 'lock-back' state. This device makes it possible to prevent a vehicle hood from being hit by the wiper arm or the wiper blade.
