A wiper rubber (8), comprising, in cross sectional shape, a head part (9) held by a wiper blade (3), at least two edge parts (18) projected downward and coming into elastic contact with a wiped surface (10) through a specified clearance under the head part (9), and a body part (16) integrally formed between the head part (9) and the edge parts (18), wherein a support part (23) coming into contact with the inner surfaces of the edge parts (18) swinging diagonal inward to support the inclined and curved attitude of the edge parts (18) when a wiper is operated is projectedly provided in a clearance (19) between the edge parts (18), whereby, by the cross sectional shape, intervals between the plurality of edge parts (18) can be reduced, the contact of the edge parts (18) on the wiped surface (10) under proper contact pressure and elasticity and the sufficiently compatible contact thereof on a curved glass surface can be realized and, as a result, the excellent wiping of rain water can be performed.
