Claims

[Scope of utility model registration request]

An arm shank having a substantially U-shaped cross-section; an arm fixed to the distal end of the arm shank to support the wiper blade; and one end of the arm being inserted into the base end of the arm shank to extend the arm shank within a certain range. In the wiper arm device, the wiper arm device includes a support rotatably supported within the wiper arm, and a spring tensioned between the base end of the arm and the support so as to bias the wiper arm in the direction of the windshield. A long hole is formed in the wall near the support so as to extend in the longitudinal direction of the arm shank, and a stopper is provided inside the arm shank near the support, and when the arm shank is locked back, a stopper is provided to connect the support to the ceiling wall of the arm shank. The stopper is arranged so as to be inserted into the gap formed between the stopper and the top surface, and is configured to be moved forward and backward by a slider that is slidably fitted into the elongated hole. Features a wiper arm device.
