PROBLEM TO BE SOLVED: To provide a microscope by which plural constituting elements with optical parts respectively attached can be combined with sure positional reproducibility. SOLUTION: The cylindrical part 71 of a second housing 3 is inserted in the through hole 72 of a first housing 2 and a ring 73, the part 71 is pressed toward a positioning protruding part 74 by a pressing means while the outer periphery of the part 71 is made to abut on the part 74, so that the housing 2 is combined to the housing 3. The part 71 is positioned by the part 71 and the two parts 74 abutting on the outer peripheral surface of the part 71, so that play caused by process common difference can be minimized in comparison with the conventional fitting structure of a recessed line part and a projected line part. Thus, the constituting elements can be combined with each other with high positional reproducibility.
