- the ejection port 34 when the ejection port 34 is inclined with the tip side directed toward the center, the cleaning liquid ejected from the ejection port 34 gathers on the blade center side. Thereby, scattering of the cleaning liquid is suppressed, and an appropriate injection position is secured even at high speed.
- the wiper blade 31 there is a difference in the discharge pressure of the cleaning liquid between the outward wiping and the backward wiping (outward ⁇ return). As described above, the scattering of the cleaning liquid tends to increase when the return path is wiped. Therefore, in the wiper blade 31, the spraying pressure (spraying speed) of the cleaning liquid at the time of wiping the return path is increased to suppress the scattering of the cleaning liquid. If the jetting pressure of the cleaning liquid is increased, the cleaning liquid reaches the glass surface without being greatly scattered even when the traveling wind is large. Therefore, even when the return path is wiped off, where the cleaning liquid is more likely to scatter, the scattering of the cleaning liquid is suppressed, and an appropriate injection position is ensured even at high speeds.
- the form of the injection port 34 is not limited to the configuration in which the angle ⁇ p is larger on the outer side of the blade as shown in FIG. FIG. 11 shows a modification of the third embodiment.

- the inside of the protrusion receiving member 122 is hollow.
- An internal space 126 communicating with the protrusion connection hole 125 is formed in the protrusion receiving member 122.
- the protrusion receiving member 122 is connected to the water channel connector 123.
- the internal space 126 of the protrusion receiving member 122 communicates with the water supply path 127 in the water channel connector 123.
- the water supply channel 127 extends in the longitudinal direction of the water channel connector 123 and opens at the tip of a water channel connection portion 128 that protrudes from both ends.
- a water channel 129 is provided in the rubber holder 103.
- the water supply channel 127 is in communication with the water channel 129 via the water channel connection unit 128.
- the water channel connecting portion 128 is provided with a spherical joint portion 127a.
- the spherical joint portion 127a can absorb the coaxial displacement of the water channel 129.
