PURPOSE:To enhance the allowable load of a support structure and as well to enhance the reliability thereof, by disposing a laminated structure which is formed by laminating rubber-like resilient members and rigid members, alternately one upon another, between a spherical member supporting a suspending rod and a spherical seat. CONSTITUTION:A support device is composed of a spherical seat 1 formed therein with a spherical concave surface, a spherical member 2 formed thereon with a spherical convex surface, and a resilient member 3 held between the former two. Holes through which a suspending rod 4 is made to pierce, are formed in the spherical seat 1, the spherical member 2 and the resilient member 3 at the center thereof. The resilient member 3 has structure such that rubber- like resilient materials 7 and rigid materials 8 are laminated alternately one upon another, and accordingly, have a high strength capable of bearing against a high load. |
