A rotary support structure for a surgical microscope is provided in which the surgical microscope can be rotated for more than one turn and can still be stopped within a number of turns to have no adverse effect on internal wirings. Since a first groove 11 and a second groove 12 in the shape of a partial arc are formed respectively on the front and back of a rotary plate 9 disposed between an end member 3 and a rotary body 6, and further a first protrusion 13 and a second protrusion 14 being formed on the end member 3 and the rotary body 6 respectively are movably linked with the first groove 11 and the second groove 12, a maximum rotated angle of the rotary body 6 (the surgical microscope M) can be enlarged up to the sum of rotatable angles of the first groove 11 and the second groove 12. <IMAGE> |
