ンスの調節に工数がかかる。[Problems to be Solved by the Invention] Conventional wiper blade rubbers have a substantially symmetrical cross-sectional shape and are therefore prone to deformation during vulcanization, and efforts have been made to prevent this. Furthermore, during molding, the center of the extruded lip part is cut with a knife in a symmetrical shape with respect to the lip part. The tip of the lip part needs to have a sharp shape, but if the blade is inserted from one side, there is a problem that the side where the blade comes out is likely to be damaged. For this reason, cutting is done from both sides, but adjusting the clearance between the cutting edges takes a lot of man-hours.

ないからである。The first side portion is one leg portion of a substantially U-shape, and the angle defined by the outer side surface and the lower end surface is the wiping angle. This wiping angle has a sharp shape and slides on the glass surface to remove adhering water droplets and the like. The wiping corner requires a sharp shape and can be formed by cutting with a blade. In this case, it is preferable to use the front side of the blade cut from the front side to the back side for the blade input during cutting. That is, the surface of the blade that can be handled during cutting tends to have burrs, which is not preferable for forming a wiping angle.

第２側部は略Ｕ字形状の他方の脚部で、外側の側面と下
端面とで規定される角が拭き角となる。The second side portion is the other substantially U-shaped leg, and the angle defined by the outer side surface and the lower end surface is the wiping angle.
