<P>PROBLEM TO BE SOLVED: To attain further stabilization of vibration proofing effect by preventing defective operations of vibration proofing materials and to achieve the reduction of component cost and the improvement of maintainability by reducing the number of parts. <P>SOLUTION: A vibration isolator of a tractor includes a vibration isolating unit 27 composed of a front component member 28 connected to one of facing V-shape links, a rear component member 29 connected to the other, and compression springs 49, 50 or the like disposed between the component members 28, 29. At least one of a reverse flexible structure 53, in which the approach of the component members 28, 29 expands the vibration proofing materials and the separation of the component members 28, 29 shortens the vibration proofing materials, and a covering structure 54, which covers and protects a damper 48 and the compression springs 49, 50 with the component members 28, 29, is provided in the vibration isolating unit 27. <P>COPYRIGHT: (C)2013,JPO&INPIT |
