Claims

[Scope of utility model registration request]

(1) A pivot shaft that rotates back and forth, an arm head with one end fixed to the shaft, an arm with one end supported on the other end of the arm head via a pivot pin, and the other end of the arm A wiper device having a wiper blade provided at a portion thereof, the blade being pressed against a wiping surface by a tension spring, comprising: a movable member that engages with the arm head and is movable in the longitudinal direction of the arm head; a spring piece that is hinge-supported so as to rotate freely and has an engaging portion that engages with the movable member;
The tension spring is tensioned between the free end of the spring piece and the arm, and the length of a perpendicular drawn from the pivot pin to the tension spring is variable by movement of the movable member, and A wiper device, characterized in that the stationary member is provided with a cam that engages with the member and automatically moves the movable member in a direction to increase the length of the perpendicular line by the wiping movement of the wiper device.

(2) The wiper device according to claim 1, wherein the stationary member is a pivot holder that supports a pivot shaft that rotates back and forth.
