Claims

[Scope of utility model registration request]

In a wiper device in which a wiper blade is attached to a wiper arm and a wiper lift-preventing fin is provided on the wiper arm, the wiper lift-preventing fin includes a wind receiver that presses the wiper arm toward the windshield surface by airflow flowing toward the windshield surface. A fin main body having a surface is provided to be tiltable, and a fin is provided between the fin main body and the wiper arm in order to reduce the pushing force against the wiper arm when the wind pressure of the air flow exceeds a predetermined value. A wiper device characterized in that a spring is provided with a rotation torque that allows the main body to be tilted by wind pressure in a direction opposite to the direction in which the main body is tilted by the spring.
