Claims

[Claims for Utility Model Registration] 1. An arm connected to a wiper blade is swingably supported on an arm head as a main arm,
The arm supporting the wing is used as a sub-arm, and the base of the sub-arm is arranged in a groove shape with a downward opening so as to cover the base of the main arm, and both sides of the base of the sub-arm swing to both sides of the arm head. What is claimed is: 1. A wiper device characterized in that a pivot portion is provided to support the main arm, and an axis passing through both pivot portions is inclined with respect to a plane including a swing axis of the main arm. 2. A wiper device according to claim 1, wherein both pivot portions each include a substantially hemispherical recess and a protrusion that engage each other. 3. The wiper device according to claim 2, wherein the lower pivot portion includes a substantially hemispherical convex portion provided on the sub-arm, a substantially hemispherical concave portion provided on the arm head, and an arcuate groove extending from the concave portion.
