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 to wipe the area with the wiper blade. a retainer mounted so as to be swingable in a plane substantially perpendicular to the windshield glass surface; 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 surface. a compression coil spring that is biased in a direction to press the spring guide; and a guide bar that is formed integrally with the spring guide, projects through the center of the compression coil spring in the longitudinal direction, and further projects through the stopper. In the wiper arm, a retainer side including the stopper;
The wiper arm is characterized in that the guide bar and the guide bar are configured so that when the retainer swings in the lock pack direction by a certain angle or more, they interfere with each other to restrict the swing in the lock back direction.

(2) Place the guide bar on the windshield glass surface side of the stopper with respect to the inner periphery of the through hole, and on the opposite side of the windshield glass surface with respect to the vicinity of the tip of the through protrusion from the stopper. The wiper arm according to claim 1, wherein the wiper arm is restrained from swinging by more than a certain angle in the lockback direction by contacting the wiper arm in the swinging direction.

(3) providing the retainer with a support portion that indirectly supports one end of the compression coil spring via the stopper, adjacent to the free end side of the retainer of the stopper;
The windshield glass surface side of the guide bar is brought into contact with the support part, and the end of the guide bar opposite to the windshield glass surface side is brought into contact with the retainer side, respectively, so that the rocking force is kept constant in the direction of the lock pack. The wiper arm according to claim 1 of the utility model registration, characterized in that the wiper arm is restricted from swinging beyond an angle.

(4) The guide bar engages with the penetrating protrusion of the guide bar from the stopper in the axial direction when the retainer force button swings in the pull-back direction for more than a certain angle, and engages in the proximal direction with respect to the retainer. The wiper arm according to claim 1, 2, or 3 of the utility model registration, characterized in that a retaining portion is provided to restrict relative movement.

(5) The wiper arm according to claim 4, wherein the retaining portion is a protrusion that is integrally formed with the guide bar and engages with the stopper.
