Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a vehicular wiper capable of preventing generation of a whistling sound even when a travel speed increases. SOLUTION: A wind bleeding hole 47 is arranged in a retainer front face 44 or a rear face 45 as a vertical wall part of a wiper arm of a vehicular wiper 1, and generation of the whistling sound is prevented by disturbing wind W1 flowing to a blade part 6. The wind bleeding hole 47 is desirably set to 75 mm2or more in its area. A vortex of a stable air current is not generated by generating turbulence in the wind flowing in a wiper blade by arranging the wind bleeding hole. COPYRIGHT: (C)2009,JPO&INPIT |
