Disclosed is an anti-skid device attached to a wheel of a vehicle, including a body (2) detachably mounted to the side of a tire wheel (1), a plurality of spike supports (21) with spikes (20) separately fixed thereto and a plurality of springs (22) arranged in a radial direction on the body (2) and being stored in the body to be movable, and an air tube (30) mounted on the body. When the air tube (30) is expanded by putting air into the tube, the springs (22) are forcibly contracted, and all the spike supports (21) are moved to each direction, so that the spikes (20) protrude to the position which comes into contact with the ground to prevent the slip of the vehicle. By contrast, When the air tube (30) is contracted by discharging the air from the tube, the springs (22) are returned, and all the spikes (20) are returned together with the spike supports (21). Since the air tube (30) is light and occupies a small space, the device is preferably designed to have a light-weight and a compact structure. Also, the device is not expensive and economical, and a lot of spikes can be arranged to improve an anti-skid effect. |
