A compaction roller comprises a vibration device 3 for generating vibrations when driven by a vibration motor 2; a pair of right and left traveling drive shafts 4, while traveling driving outside tires T1, T4 and their adjoining inside tires T2, T3 synchronously, for transmitting the vibrations of the vibration device 3 to the outside tires T1, T4 and inside tires T2, T3; a pair of right and left traveling motors 5 respectively for driving their associated traveling drive shafts 4; and, a pair of right and left first support brackets 8 mounted through a first vibration proof device 6 on a vehicle body and interposed between the outside tires T1, T4 and inside tires T2, T3 for supporting the traveling drive shafts 4 through bearings 7, wherein the vibration device 3 includes a vibration source disposed within the traveling drive shafts 4. According to the compaction roller, a side overhang can be eliminated or reduced, and enabling prevention of the lowered vibration compacting function of the tires.
