Abstract
A shock absorber and a metal cover reduce contact noise generated as a shock absorbing member hits a collar and have higher vibration damping performance. A shock absorber absorbing vibration to a heat insulator covering an exhaust manifold as a vibration source includes a collar, a grommet, an annular compression mesh including a shock absorbing material, and a spiral spring overlaid on a compression mesh. The compression mesh has a center hole loosely receiving a collar shaft. The spiral spring spiral in a plan view has a spring constant equal to or smaller than that of the compression mesh. The compression mesh includes a restriction ridge along a lower large-diameter portion to restrict radial movement of the spiral spring relative to the compression mesh. The circumferential contact area X of the lower large-diameter portion with the restriction ridge ranges between 40% and 55%.
