PURPOSE: To guarantee excellent sound insulating performance by forming a resilient body having a wound body comprising a plurality of concentric fiber wound layers and a fiber layer extended at an angle relative to the concentric layers, forming fixed parts by force-inducing elements formed of arcuate pieces, through rubber layers, and surrounding the wound body partially with the arcuate pieces. CONSTITUTION: A wound body 1 comprises plural layers of fibers mainly wound annularly at a right angle to a load direction. One layer, particularly the center layer 3, out of the layers of the wound body 1 comprises woven fabric provided with laterally extended fibers or fibers wound at a different angle from the outer layer 2. The wound body finished with winding, impregnated and hardened is fixed to a suitable point through suitable force-inducing elements disposed at two opposed side faces. The force-inducing element is formed of arcuate pieces of two joint plates 6, 7 of U-shape tightened to each other through side face bars 8, 9, and elastic intermediate layers 10, 11 formed of rubber are arranged between the joint plates 6, 7 and the wound body 1. |
