Abstract
There is provided a surgical microscope having a horizontal movement arm portion which moves a microscope portion in a substantially horizontal direction, and a vertical movement arm portion which moves the microscope portion in a substantially vertical direction. A first elastic force generation mechanism connected with a base bottom portion and the horizontal movement arm portion generates an elastic force which offsets a rotation moment around a first horizontal rotation axis produced when the horizontal movement arm portion revolves around the first horizontal rotation axis arranged in the base bottom portion. Further, a second elastic force generation mechanism connected with the base bottom portion and the vertical movement arm portion generates an elastic force which offsets a rotation moment around a second horizontal rotation axis produced when the vertical movement arm portion revolves around the second horizontal rotation axis arranged in the horizontal movement arm portion.
