ABSTRACT:
A viewing tube for a microscope has an optical deflecting element such as a mirror for deflecting light from an objective, a supporting member for supporting the optical deflecting element and an eyepiece portion into which the light deflected by the optical deflecting element enters. The supporting member is rotatable around a first shaft and the eyepiece portion is rotatable around a second shaft. An engaging member is mounted on the eyepiece portion in a position whose distance from the second shaft is equal to the distance between the first shaft and the second shaft. Guiding members are provided on the supporting member for engaging with the engaging member and restricting the engaging member in the circumferential direction around the first shaft, so that the supporting member and the optical deflecting element are rotated around the first shaft in accordance with rotation of the eyepiece portion around the second shaft.
