  • Wiper device
    Patent number: 10625714
    Abstract: Base end sides of washer tubes 44, 45 are arranged in an axial direction of a swinging shaft PS at one end portion of an arm head 40, and they are drawn out from a head side pipe housing portion 41a so as to curve toward a side opposite to a shaft fixing portion 42 side. Each of the washer tubes 44, 45 is wound around the shaft fixing portion 42 during swinging of the arm head 40 without applying any load to the swinging shaft PS. No tension acts on each of the washer tubes 44, 45, and each of the washer tubes 44, 45 is not rubbed against the shaft fixing portion 42. Therefore, deterioration of the washer tubes 44, 45 can be suppressed. When the washer tubes 44, 45 are wound around the shaft fixing portion 42, a periphery of the shaft fixing portion 42 is suppressed from swelling outward in a radial direction thereof. This makes it possible to prevent the arm head 40 around the swinging shaft PS from increasing in size.
