In a cross-sectional structure of an existing blade rubber having a non-hollow cross-section, only elasticity of a material of the blade rubber is used for pressure to wipe a windshield. Therefore, it is difficult for the blade rubber to flexibly follow change of a surface shape of the windshield, and sufficient wiping performance is not obtainable. A blade rubber to be attached to a frame of a vehicle wiper and to wipe the windshield according to the present invention includes a wing portion extending in a lateral direction to fix the blade rubber to the frame, a neck portion perpendicularly coupled to the wing portion, a deformation portion elastically deformable and coupled to a lower side of the neck portion, and a contact portion provided on a side of the deformation portion opposite to a side provided with the neck portion, and configured to abut on the windshield. The deformation portion internally includes a cavity portion having a heart-shaped cross-section. The neck portion is coupled to an upper intersection of two curved portions surrounded by an outside of the deformation portion and the heart-shaped cavity. The contact portion is coupled to a lower intersection.
