Claims

[Claims for Utility Model Registration] 1. An arm head attached to a drive means so as to be swingable around a swing axis, and an arm head attached to the arm head via the pivot shaft so as to be pivotable within a plane substantially including the swing axis. a retainer attached to the wiper blade to support the wiper blade; a link having one end connected to the arm head via a link shaft substantially parallel to the pivot axis and the other end extending in the direction of the swing axis; and the other end of the link and the retainer. an arm spring tensioned between the retainers to urge the retainer in a predetermined direction; an adjusting means for adjusting the angular position of the link around the link axis; and a link that acts on the link by the spring force of the arm spring. A wiper device comprising: spring means for resisting torque about an axis. 2. The wiper device according to claim 1, wherein the spring means is a leaf spring acting between the arm head and the link. 3. Claim characterized in that the adjusting means includes a slider slidably provided on the arm head while supporting a link pin connecting the other end of the link and the arm spring, and a motor for slidingly moving the slider. The wiper device according to claim 1 or claim 2. 4. The wiper device according to claim 3, wherein the adjusting means includes a motor and a mechanism connecting the motor and a link.
