Title:
WIPER BLADE
Document Type and Number:
Japanese Patent JP2010083471
Kind Code:
A
Abstract:

To enhance wiping-out performance of a wiper blade when a vehicle travels, by restraining a water pulling phenomenon after reversal operation.

An interval between an inner surface 31c1 of a rear wall 31c of a rubber holder 31 and blade rubber 32 is formed so as to gradually become wider toward a central part from both end parts in the longitudinal direction of the rubber holder 31 than an interval between an inner surface 31b1 of a front wall 31b and the blade rubber 32. An interval between an inner surface of a rear wall of a pair of covers connected to both end parts in the longitudinal direction of the rubber holder 31, and the blade rubber is also formed so as to gradually become wider toward the central part from both end parts in the longitudinal direction of the covers than an interval between the inner surface of the front wall and the blade rubber. Thus, when the vehicle travels, a traveling wind is made to easily flow between the rubber holder 31 and the blade rubber 32 and between the covers and the blade rubber 32.
