Provided is a washer liquid supply system in a simple structure and capable of improving the capacity of washing an object of a vehicle. A washer liquid supply system includes: a washer tank mounted on a vehicle to store washer liquid; a supply section mounted on the vehicle to supply the washer liquid in the washer tank to a window shield of the vehicle; and a connecting member being a bubbling section mounted on the vehicle to make the washer liquid contain bubbles, wherein the supply section supplies the washer liquid containing the bubbles to the window shield.

Washer liquid supply system

A washer liquid supply system is disclosed which includes: a washer tank mounted on a vehicle to store washer liquid; a supply section mounted on the vehicle to supply the washer liquid in the washer tank to an object of the vehicle; a heat-retaining tank mounted on the vehicle and disposed between the washer tank and the supply section to temporarily store the washer liquid supplied from the washer tank to the supply section; a delivering section mounted on the vehicle to deliver the washer liquid stored in the washer tank to the supply section through the heat-retaining tank; and a control section that controls the delivering section, wherein the control section controls the delivering section to temporarily increase a delivering amount of the washer liquid at an initial time of supplying the washer liquid.

injection positions (A, B, and C) toward which washer liquids (W) are injected from the forward-side injection nozzles (A, B, and C) and injection positions (Dand E) which washer liquids (W) are injected from the backward-side injection nozzles (Dand E) are alternatively shifted in the longitudinal direction of the blade rubber. Therefore, in wiping-out motion of the blade rubber for one reciprocation, the front glass () can uniformly get wet, the total number of injection nozzles can be made less than ever, the consumption amount of washer liquid (W) at the time of reciprocating wiping-out motion of the blade rubber can be reduced, power consumption of the washer pump can be reduced, and the size of the washer pump can be decreased.

Wiper blade

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

A nozzle unitwhich jets washer fluid toward a windshield is fixed to an arm piecewhose front end side is fitted to a hook fixing member. As a result, the nozzle unitcan be fixed without using the fitting member adopted in the conventional case, and located closer to the hook fixing member. This reduces a positional shift of the nozzle unitrelative to the wiper bladeto the minimum, thus stabilizing the injection-target locations of washer fluid on the windshield.

Wiper apparatus and nozzle unit

A washer apparatusis provided to a coupling portion CN between a blade rubberand a holder member, and has a length in a longitudinal direction of the blade rubber, which is set to be shorter than that of the blade rubberin the longitudinal direction, and inner-peripheral-side-oriented injection nozzlesandand an outer-peripheral-side-oriented injection nozzlehave openings oriented to respective ends of the blade rubberin the longitudinal direction.

A wiper apparatus is improved in wiping performance, and can suppress a disturbance due to cleaning liquid in a driver's field of view. Each cleaning liquid Wand Wis jetted from four forward-side injection nozzles and four backward-side injection nozzles in a direction opposite to the wiper blade, and toward injection-target locations, and a distance between the wiper bladeand an injection-target location for cleaning liquid Wand Won the opposite side from a center of a swinging motion of the wiper bladein a wiping direction of the wiper bladeis larger than a distance between the wiper bladeand an injection-target location for cleaning liquid Wand Won the same side as the center of the swinging motion of the wiper blade in the wiping direction of the wiper blade. Therefore, on the same side as the center of the swinging motion of the wiper blade, it is possible to suppress a disturbance due to cleaning liquid in the driver's field of view, and on the opposite side from the center of the swinging motion of the wiper blade, it is possible to enhance the wiping performance of the wiper apparatus by sufficiently wetting dust and the like.

Wiper apparatus

In a vehicle with a tailgate, a rear opening is formed in a rear surface of a vehicle body, a tailgate that is provided to open and close the rear opening, a sub-door opening that is formed in a portion of the tailgate in a width direction, and a sub-door that is provided to open and close the sub-door opening. The vehicle includes a tailgate latch device that locks the tailgate with the vehicle body, a sub-door latch device that locks the sub-door with the vehicle body, and a control unit that controls the tailgate latch device and the sub-door latch device. The control unit controls the sub-door latch device so as to prohibit the sub-door from being opened when determining that the tailgate is opened.

Vehicle with tailgate

A wheeled vehicle includes a rear opening that is formed in a rear surface of a vehicle body, a tailgate that is provided to open and close the rear opening, a sub door opening that is formed in a transverse portion of the tailgate, and a sub door that is provided to open and close the sub door opening. In the tailgate, a tailgate side window panel is provided on the tailgate, and a sub door side window panel is provided on the sub door. These tailgate side window panel and the sub door side window panel are made substantially level with each other while being disposed continuously in a transverse direction. The control unit prohibits the operation of a wiper device that moves over the individual window panels so as to clean and remove water therefrom, with the sub door left open.
