<p>An elastic wheel, comprising a disk (1) having a base rim (2) and a rim (3) pivotally supporting a tire (10), wherein a projected part (5) with a generally trapezoidal cross-section in the wheel axis direction is formed in a well of the rim (3), and a pair of elastic rubber bodies (6) are provided annually between the outer surfaces of a pair of wall parts (4a, 4b) formed by bending the both sides of the base rim (2) at a sharp angle and the rim inner peripheral surface of the generally trapezoidal projected part (5), whereby vibration can be absorbed by both the shearing deformation and compressive deformation of the installed elastic rubber bodies (6) so as to increase riding comfort, vibration proofing, and sound proofing performances in the area ranging from small input to large input, the sound proofing performance being very effective for sound in a high frequency area of 100 Hz or higher.</p> |
