The invention discloses a brushing mechanism for a windshield wiper. The brushing mechanism comprises a longitudinally arranged soft adhesive tape, wherein a longitudinal groove is arranged in the soft adhesive tape and a sponge strip fills the groove. According to the invention, the groove for accommodating the sponge strip is arranged in the middle of the traditional soft adhesive tape, so that the brush has a water-absorbing function; when the glass is cleaned, water on the glass is not directly scraped off but is absorbed by the sponge strip; under an extruding effect of the soft adhesive tape, the glass is gradually wetted, so that a better cleaning effect is achieved.
