Claims

[Scope of utility model registration request]

(1) An arm head whose base end is attached to a swingable pivot shaft, a wiper blade supported on the tip side, and a swing shaft at the tip of the arm head at the base end, which wipes with a front wiper blade. a retainer mounted so as to be swingable in a plane substantially perpendicular to the windshield glass surface, and at a position offset in a direction away from the windshield glass surface with respect to the swing axis of the arm head; A spring guide is pivotably supported by a swing shaft so as to be able to swing freely in substantially the same plane as the retainer, and the spring guide is mounted between the spring guide and a stopper on the retainer side, and the tip side of the retainer is connected to the windshield glass. a compression coil spring biased in a direction to press against a surface; and a guide bar formed integrally with the spring guide and projecting through the center of the compression coil spring in the longitudinal direction, and further projecting through the stopper. In the wiper arm, the stopper is swingably supported at one end on the retainer via a support shaft parallel to the swing axis at a position closer to the free end of the retainer than the tip of the guide bar, and A through hole is formed on the side, through which the tip of the guide bar is inserted; When the spring guide comes into contact with the spring guide, the sum of the distance between the swing axis of the spring guide and the tip of the stopper and the length of the stopper is larger than the distance between the swing axis and the support axis of the stopper. wiper arm.

(2) Utility model registration claim 1, characterized in that a locking mechanism is provided between the side surface of the stopper and the inner side surface of the retainer opposing the stopper to restrict the rise of the stopper. Wiper arm as described in section.

(3) The point of contact between the tip of the compression coil spring and the stopper can be crossed over to a position farther from the windshield glass surface than a straight line passing through the swing axis of the spring guide and the support axis of the stopper. The wiper arm according to claim 1 or 2 of the utility model registration claim, characterized in that:
