A support device for supporting a supported structure above a supporting structure, in which a ball (2) is rotatably held at the top of a first component (A) disposed on the side of either one of the supporting structure and the supported structure, and a second component (B) is so supported that this ball can be in rolling contact with a concave surface (3) of the second component, which is disposed in contact with the side of the other of supported structure and the supporting structure. On the outer side of the first component (A), a support cylinder (11) is slidably fitted, and this support cylinder (11) and the second component (B) are hinge-coupled by a parallel-linkage mechanism. The support cylinder (11) is pulled toward one of the sides by a pulling mechanism, the ball (2) and the concave surface (3) of the second component being pressed into contact, and the centripetal force acting between the ball and the concave surface is utilized to stably hold the supported structure in a normal position on the supporting structure. This support device can be used as a support device of bodies of transportation facilities and architectural structures.
A support device constituted by having a first component disposed on the side of either one of a supporting structure and a supported structure, a second component disposed on the side of the other and provided with a concave surface, a spherical structure held by said first component and being in rollable contact with the concave surface of the second component, an elastic support mechanism elastically supporting either one of said first component and second component on a confronting support surface, a holding mechanism of the second component held in a manner to be slidable along the outer side of said first component and hinge-coupled to said second component, and a pulling mechanism for pulling said second component in one direction so that said concave surface and spherical structure will be in pressing contact.
