PROBLEM TO BE SOLVED: To provide a support and drive structure of a rolling compaction tyre eliminating a necessity of support of an axial load of a vehicle by a hydraulic motor driving the rolling compaction tyre. SOLUTION: A tyre support member 3 is provided in a central part of vehicle width of a rear part vehicle body 2. A central part in the direction of vehicle width of an axle 4 is rotatably supported on a bearing 6 attached to the tyre support member 3. The bearing 4 has the specifications sufficient for supporting an axial load. A pair of rolling compaction tyres 17 are integrally connected with hubs 8 on both sides of the axle 4, respectively, to support the axial load by the bearing 6 exclusively. A drive motor support member 20 is provided by corresponding to the rolling compaction tyre 17 on one end side in the direction of vehicle width in the vehicle body, the hydraulic motor 30 is attached to the drive motor support member 20 coaxially with the axle 4, and a drive plate 33 integral with a rotary output body 32 of the hydraulic motor 35 is connected with an opposing disc wheel 15 of the rolling compaction tyre 17.
