パー装置。[Claims for Utility Model Registration] It has a motor arm that is rotationally driven around its base end by a wiper motor, and one end of a link member is rotatably connected to the distal end of the motor arm via a shaft. In a wiper device that swings a wiper arm via a link member by rotation of a motor arm, an eccentric disc is interposed at a connection between the tip end of the motor arm and one end of the link member, and the rotation of the eccentric disc is A counter is provided on the eccentric disc so that the effective length of the motor arm is expanded or contracted by the rotation of the motor arm, and the eccentric disc is set to rotate by centrifugal force when the motor arm rotates at high speed, thereby shortening the effective length. A wiper device characterized by having a weight attached to it.
