Claims

[Scope of utility model registration request]

A wiper capable of operating along the outer surface of a window glass of a vehicle and an electric mechanism for driving the wiper are provided, and an electric heating element for defrosting is attached to the window glass at a retracted position of the wiper,
a changeover switch capable of turning on only one of the electric heating element and the electric mechanism;
A freeze detector capable of detecting the frozen state of the outer surface of the window glass of the wiper in the retracted position at the initial stage of transition of the electric mechanism to the on state, and a freeze detection signal from the detector to switch the changeover switch to the electric A wiper device for a vehicle with a defrosting mechanism, characterized in that the wiper device for a vehicle with a defrosting mechanism is provided with a control means capable of switching the mechanism from an on state to an on state of the electric heating element.
