Claims

[Scope of utility model registration request]

A flange is integrally formed protruding at right angles to the plate surface of the outer circumferential surface of a rotating body having a substantially cylindrical outer shape and rotatable around an axis, and this flange is formed with a holding surface perpendicular to the plate surface of the outer circumferential surface. a polyhedral annular mirror body is fitted to the rotating body, and the mirror body is fixed to the rotating body with one surface perpendicular to the plate surface of the outer peripheral surface of the mirror body facing the holding surface, In the rotating mirror in which the mirror body rotates around the axis as the rotating body rotates, the rotating body includes a holding body that faces the flange and moves on the outer circumferential surface in parallel to the axis. A second holding surface is formed at a position opposite to the holding surface of the holding body and is perpendicular to the plate surface of the outer circumferential surface, and is arranged to freely fit on the outer circumferential surface of the rotating body. A clamping body is provided on a side opposite to the side on which the second holding surface of the holding body is formed, and is in pressure contact with the second holding surface of the holding body and the mirror body. A mirror body disposed to fit on the outer circumferential surface between the holding bodies has one surface perpendicular to the outer circumferential surface facing the holding surface, and the other surface perpendicular to the outer circumferential surface facing the second holding surface. A rotating mirror characterized in that the rotating mirror is configured to be elastically clamped by the flange and the holder in contact with each other.
