PURPOSE:To reducing the quantity of operating force of the focusing device of a microscope by applying an elastic member with an angular moment in the opposite direction of an angular moment originating from the load on a mirror body, and balancing both moments with each other. CONSTITUTION:The focusing device of the microscope is provided with the 1st link 20 which constitutes a rotary member supported pivotally on a link support member 21 fitted at one terminal fixedly to a focusing part body 3 and the 2nd link 22 which is supported at one terminal pivotally on a link support member 23 arranged fixedly to the mirror body and further supported at the other terminal pivotally and closely to the free end of the 1st link 20. Further, the elastic member 24 such as a spring is extended between the free end of the 1st link 20 and the focusing part body 3 and the 1st link 20 is applied with the angular moment in the opposite direction of the angular moment applied to the 1st link 20 through the 2nd link 22 owing to the load on the mirror body 5. |
