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.

Wiper blade

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

A wiper blade includes a blade rubber and a rubber holder. In the rubber holder, a water channel through which a washing liquid flows along a longitudinal direction is provided. In the rubber holder, an injection port that communicates with the water channel and is configured to be opened by water pressure and inject the washing liquid is provided. The injection port is formed into a slit shape, and a plurality of injection ports are provided in the longitudinal direction. A width of the injection ports varies along the longitudinal direction, and the injection port closer to an outer end side has a larger slit width. A larger amount of the washing liquid is injected from the injection port having a larger slit width, and the injection amount of the washing liquid becomes larger toward the outer end side at which more washing liquid is required.
