Abstract

The present invention relates to an anti-skid device for a tire, comprising: fixed plates fixed to a wheel of the tire, the fixed plates each having a cylindrical nut-type fastening means with a thread formed on the inner circumferential surface in the center thereof; a supporting plate having a body part with an insertion hole formed in the center thereof and a plurality of connecting plates which are formed to radially protrude on the outer circumferential surface of the body part; anti-skid arms fixed to the connecting plates; and a locking plate for fixing the supporting plate between the fixed plates. The locking plate has a disc-shaped body between which and the fixed plates the body part of the supporting plate is interposed, and a bolt-type fastening means which is formed to protrude on the lower surface of the disc-shaped body and which has a thread formed on the outer circumferential surface so that the bolt-type fastening means can be coupled to the nut-type fastening means in a screw fastening manner.
