The cuts 4 are provided with a spiral-like twist in the depth direction, centered on the imaginary axis 2, and a twist angle ¸ thereof is not less than 10° and less than 135°. Additionally, a length in the radiation direction of the cuts 4 or a width of the cuts is formed larger at a tread surface 1 side than at a bottom surface side.",
