A tilting device for surgical microscopes comprising: a supporting apparatus composed of a parallelogram link mounted to be movable three-dimensionally on a frame through a mounting member; and a spring connected between another end portion distant from one end portion of a supporting member to support a microscope and the mounting member, in which rotation moment caused by the weight of the microscope with rotation of the center of gravity of the microscope attached to one end portion of the supporting apparatus is adapted to be offset by reverse rotation moment relying on the elasticity of the spring, in order to make it possible to secure a wide working space for operations in spite of a small size, simplify the structure, reduce the cost of manufacture, and perform smooth operation in the best balance. |
