Abstract
An elastic wheel, comprising a disk ( ) having a base rim ( ) and a rim ( ) pivotally supporting a tire ( ), wherein a projected part ( ) with a generally trapezoidal cross-section in the wheel axis direction is formed in a well of the rim ( ), and a pair of elastic rubber bodies ( ) are provided annually between the outer surfaces of a pair of wall parts ( ) formed by bending the both sides of the base rim ( ) at a sharp angle and the rim inner peripheral surface of the generally trapezoidal projected part ( ), whereby vibration can be absorbed by both the shearing deformation and compressive deformation of the installed elastic rubber bodies ( ) 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.
