CONSTITUTION: A snow chain comprises a first outer wire(21), a second outer wire(22), inner wires(25), cross wires(30), and hooks. The outer wires are formed along the circumferential direction of a tire and arranged in the outmost edges of the chain. The inner wires are arranged with constant space between the outer wires. The cross wires are formed to cover the width direction of a tire and the both ends are connected with outer wires respectively. The hooks are formed in the outer wires and inner wires.
