The invention provides a lateral shake buffering structure for a drill bit. The lateral shake buffering structure comprises an annular plate, a plurality of supporting rods, a plurality of springs, aplurality of extruding plates, an inner ring and an outer ring. According to the lateral shake buffering structure for the drill bit, the springs apply acting force to the bit circumferentially, thus,in the working process of the bit, shake in the circular section direction of the bit can be buffered through the springs, and accordingly the risk of line deviation in the advancing process of the bit is lowered.
