Claim Text:
1. A vibration absorbing apparatus comprising: a first member that is a vibration source; a second member; and a vibration absorbing mechanism which works to absorb vibration, as transmitted from the first member to the second member, the vibration absorbing mechanism including a spring mechanism and an elastic member, the spring mechanism including a tapered spring body and a cylindrical protrusion, the spring body having a central hole formed therein and being elastically deformable in an axial direction thereof, the cylindrical protrusion extending in the axial direction of the spring body from at least one of an inner periphery and an outer periphery of the spring body, the elastic member being made of a non-metallic material and of a cylindrical shape, the elastic member being arranged coaxially with the spring mechanism, the elastic member having a spring constant in a radial direction thereof which is lower than that in an axial direction thereof; wherein the vibration absorbing mechanism also includes a bar-shaped fastener which joints the second member, the spring mechanism, and the elastic member together, the spring mechanism consisting of a first spring and a second spring, at least the first spring having the tapered spring body and the cylindrical protrusion, the second member having formed therein a hole through which the fastener passes, the elastic member having formed therein a hole into which the fastener is inserted, wherein the first spring is retained between the second member and the elastic member, the second member being held between the first spring and the second spring, and wherein the fastener passes through the hole of the second member and the central hole of the spring body and is disposed in the hole of the elastic member to make a joint of the second member, the first spring, and the second spring, and wherein the elastic member is secured to the first member.
