Abstract
A compaction roller comprises a vibration device for generating vibrations when driven by a vibration motor; a pair of right and left traveling drive shafts, while traveling driving outside tires and their adjoining inside tires synchronously, for transmitting the vibrations of the vibration device to the outside tires and inside tires; a pair of right and left traveling motors respectively for driving their associated traveling drive shafts; and, a pair of right and left first support brackets mounted through a first vibration proof device 6 on a vehicle body and interposed between the outside tires and inside tires for supporting the traveling drive shafts through bearings, wherein the vibration device includes a vibration source disposed within the traveling drive shafts. 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.
