Base end sides of washer tubesare arranged in an axial direction of a swinging shaft PS at one end portion of an arm head, and they are drawn out from a head side pipe housing portionso as to curve toward a side opposite to a shaft fixing portionside. Each of the washer tubesis wound around the shaft fixing portionduring swinging of the arm headwithout applying any load to the swinging shaft PS. No tension acts on each of the washer tubes, and each of the washer tubesis not rubbed against the shaft fixing portion. Therefore, deterioration of the washer tubescan be suppressed. When the washer tubesare wound around the shaft fixing portion, a periphery of the shaft fixing portionis suppressed from swelling outward in a radial direction thereof. This makes it possible to prevent the arm headaround the swinging shaft PS from increasing in size.

Wiper device

In a wiper apparatus, a gear case of a gear part is provided with a first frame fixing part which is fixed to a frame member by fastening volts and fastening nuts. An attachment bracket has a second frame fixing part which is fixed to the frame member together with the first frame fixing part by the fastening volts and the fastening nuts, and has an insertion pin which is fixed to a rear-side vehicle-body panel. A wiper motor can be fixed to the frame member together with the attachment bracket by the same fastening members, and it is possible to reduce the weight of the wiper apparatus by reducing the number of the fastening members. It is possible to enhance the productivity of the wiper apparatus by reducing the size of the attachment bracket separated as a dedicated part from the gear case.
