A spare tire carrier having a housing fixed to the automobile body, a roller assembly rotatably mounted at a rotary shaft of the housing and constructed with a plurality of closely-adhered roller plates to allow a wire to wind and unwind therebetween, and a gear plate fixed to one side of the roller assembly and formed with a first gear having a predetermined length of diameter, the carrier comprising: a plurality of split-constructed contact gears respectively meshed to a part of the first gear; an eccentric cam formed at the rotary shaft; and a resilient member mounted between the eccentric cam and the plurality of contact gears to apply a pressure to the plurality of contact gears towards the first gear, such that the wire is prevented from being squeezed in a gap of the roller assembly and the carrier is prevented from being inoperable, while the carrier swiftly operates to prevent the first and second gears from being broken down when an excessive force is applied and strength of an accommodation plate where the spare tire is seated is strengthened to thereby prevent its breakage even if frequent replacement of the spare tire occurs.
