Only a front end part 16 of a surgical microscope 15 is turned in a left-right direction X around a main axis S, so that an observation angle of a surgical site T is freely changed in the left-right direction. Even if the observation angle is changed, the orientation of eyepieces 22 is unchanged, and therefore, an operator does not need to bend his or her neck and no burden is imposed on the neck of the operator even if the operator must conduct an operation that takes a long time.
