PURPOSE:To prevent surely a neutral holding tool from being broken during use by giving the structure, where a holding member consisting of an elastic member is stuck to cover collars of a sleeve, to the neutral holding tool which holds a lens holding cylinder. CONSTITUTION:A lens holding cylinder 8 which holds an objective lens 30 is press-fitted to a neutral holding tool 26. The neutral holding tool 26 is pierced by a fulcrum shaft 2, and its outside peripheral surface is supported by a base body, and the neutral holding tool is so provided that the objective lens 30 can be turned and moved vertically. With respect to the structure of this neutral holding tool 26, a primer liquid is applied to collars 27b of a sleeve 27, and a rubber solution is flowed to the sleeve 27 in a prescribed mold, and a holding member 28 consisting of an elastic member is stuck to cover collars 27b. Thus, the holding member 28 is stuck firmly, and the holding tool 26 is prevented surely from being broken during use. |
