Elastic wheel
An elastic wheel having a disk 1 equipped with a base rim 2 and a rim 3 for supporting a tire includes a pair of guides 4 fixed annularly on the inner peripheral surface of the rim 3 and a pair of wall portions 5 fixed annularly on the both side areas in the axial direction of the wheel on the outer peripheral surface of the base rim 2, where rubber elastic bodies 6 are fitted annularly between the side surfaces of the guides 4 and the side surfaces of the wall portions, respectively. The elastic bodies 6 being installed are able to absorb vibrations by their shearing deformations, so that especially the riding comfortableness performance, the vibrationproof performance, and the soundproof performance can be improved against the small input load. Regarding the soundproof performance, furthermore, it is extremely effective on a high frequency area of 100 Hz or higher.
