<p>An elastic wheel comprising a disk (1), a rim (3) supporting a tire (20), a pair of guides (4) annularly fixed on the inner peripheral surface of the rim (3), a pair of walls (5) annularly fixed in two regions axially of a wheel shaft on the outer peripheral surface of a base rim (2) disposed on the disk (1) or the outer peripheral surface of the disk (1), and rubber elastic bodies (6) each annularly interposed between the lateral surface of the guide (4) and the lateral surface of the wall (5), wherein at least one belt (8) is annularly arranged on each rubber elastic body (6). The shear deformation of the installed rubber elastic bodies (6) absorbs vibration and particularly riding quality associated with low input, vibration prevention performance and sound insulation performance can be improved and so can steering stability. As for sound insulation performance, the elastic wheel is very effective for sound insulation in high frequency regions of 100 Hz or more.</p> |
