PROBLEM TO BE SOLVED: To provide a support structure that is excellent in workability of a tilt adjustment with a simplified configuration regarding optical means to be inserted/detached to/from an optical axis of an imaging optical system.SOLUTION: An optical means support structure comprises: an insertion/detachment frame that is pivotally supported by a rotary shaft in parallel with an optical axis of the imaging optical system with respect to a base member and causes optical means to be inserted/detached/rotated on the optical axis; a first pressing member that presses the insertion/detachment frame to an insertion position; a stopper on the base member that determines the insertion position with the insertion/detachment frame brought into contact; a support ring that supports the base member inside tiltably to the optical axis; a second pressing member that presses the base member in the support ring in the optical direction; and a plurality of adjustment screws that is screwed to the support ring and supported advanceably and retreatably to and from the optical axis direction, comes into contact with the base member from an opposite side of an action direction of a pressing force of the second pressing member to cause the base member to advance/retreat to and from the optical direction, and thereby changes a tilt angle of the base member. The plurality of adjustment screws are arranged separately in one and the other of an area across a plane surface passing through the stopper and the rotary shaft of the insertion/detachment frame. |
