| Zusammenfassung: | PROBLEM TO BE SOLVED: To easily attach and detach a turn slide eye cover member to/from an eye-piece lens holding member. SOLUTION: The eye-piece lens holding member 202 has a cam groove 203 that guides the movement of the turn slide eye cover member 300 along the outer peripheral surface of the member 300. The turn slide eye cover member 300 includes a cam follower 302 with a projection 304 that slidably enters the cam groove 203. The cam groove 203 is connected to an introduction groove 204 that has an introduction opening 206 used for the projection 304 to enter the cam groove 203 in the process of moving the turn slide eye cover member in the direction of an optical axis, thereby attaching the member to the eyeglass lens holding member 202.
