Claims

[Scope of utility model registration request]

(1) A wiper arm that moves while pressing the wiper blade against the wiping surface, a lift detector that detects the state quantity related to the lift of the wiper arm, a pressure control circuit that generates a pressure control signal based on the detected lift value, and a wiper of the wiper arm. A wiper device comprising: a pressing force adjustment mechanism that adjusts and controls blade presser pressure in accordance with a pressing control signal.

(2) Utility Model Registration In the device described in claim (1), the wiper arm includes an arm head connected to the wiper shaft, and a wiper arm driven by 5 to the wiper shaft via the arm head and attached to the tip. The pressing force adjustment mechanism includes a retainer that moves the blade along the wiping surface, and a spring that has one end attached to the retainer and presses the wiper blade against the wiping surface via the retainer. a driven motor; a drive mechanism that drives the other end of the spring in an expansion/contraction direction by the driving force of the motor;
A wiper device comprising:

(3) Utility model registration In the device described in claim (2), the spring consists of a coil spring, the motor consists of a DC motor attached to the arm head, and the drive mechanism is attached to the drive shaft of the DC motor. The worm gear that was
A wiper device comprising: a wheel gear that is rotatably supported by an arm head and meshes with a worm gear; and an eccentric shaft that is provided eccentrically on the wheel gear and drives the other end of a coil spring in an expansion/contraction direction.
