The present invention relates to a kerf structure for a snow tire, including a wave-shaped straight portion and an expansion portion formed expanding from the straight portion, wherein the expansion portion includes unit structures, on each of which central semi-sphere holes and polygonal forms around the semi-sphere holes form protrusions in opposite directions are formed continuously. According to the present invention, the kerf structure for a snow tire provides a symmetric shape, thereby securing uniform block rigidity regardless of the direction of the kerf, and the interlocking effect can be maximized through the combination of the protrusion shape of the polygonal shape and the embossing of the semi-sphere hole. In addition, according to the present invention, the tire performance on dry roads can be ensured by optimizing the collapse of the tire tread portion and the uniform performance of the traction can be maintained until the last stages of tread wear since the polygonal shape is maintained until the last stage of the wear even though the tire is worn.
