PROBLEM TO BE SOLVED: To attach and detach an inner drive wheel and outer drive wheel separately to or from a driving shaft by fastening or unfastening wheel nuts from outside a compacting equipment, in the compacting equipment for fixing the inner and outer drive wheels to a wheel hub unitized as a unit with the driving shaft by fastening wheel nuts and hub bolts. SOLUTION: A wheel hub 42 is fixedly mounted or integrally formed at the end of a driving shaft 16 of a compacting equipment 40. Wheel discs 51, 52 respectively of an inner drive wheel 43 and outer drive wheel 44 are abutted and fitted at the periphery of the wheel hub 42. Furthermore, bolt insertion holes are formed in the wheel hub 42 and the wheel discs 51, 52 respectively of the inner drive wheel 43 and the outer drive wheel 44. After inserting hub bolts 9 through the bolt insertion holes from inside to outside, a first wheel nut 59 is screwed on each hub bolt 9 so as to fix the inner drive wheel 43 to the wheel hub 42. Then a second wheel nut 60 is screwed on the outer peripheral face of the first wheel nut 59 so as to fix the outer drive wheel 44 to the wheel hub 42.
