Claims

[Claims for Utility Model Registration] (1) A mirror holder for holding the mirror is provided with a frame along the outer peripheral edge of the substrate located on the back side of the mirror, and a clamp protruding inward at the tip of the frame. and a step-shaped mirror abutting surface is provided on the substrate near the outer periphery, and the mirror is held between the mirror abutting surface and the holding part, wherein the mirror holder is integrally made of synthetic resin. A plurality of elastic protrusions are formed at intervals on the mirror abutting surface, and the elastic protrusions are brought into contact with the back surface of the mirror with elastic displacement, so that the elastic protrusions and the tip of the frame A mirror holding structure characterized by elastically holding a mirror between a holding part. (2) In the mirror holding structure described in claim (1) of the above utility model registration, the elastic protrusion is a disk-shaped flexible portion that projects toward the rear surface of the mirror in a substantially disk shape, and the circular A mirror holding structure characterized in that the center of the plate-like flexible part is in contact with the back surface of the mirror. (3) In the mirror holding structure described in claim (1) of the above-mentioned utility model registration, a both-end fixed beam feature is formed as the elastic protrusion, and the both-end fixed beam feature comes into contact with the back surface of the mirror approximately at the center thereof. A mirror holding structure characterized by: (4) In the mirror holding structure described in claim (1) of the above-mentioned utility model registration, a disc spring feature with a hole is formed in the center as the elastic protrusion, and the hole edge of the disc spring feature is used to hold the mirror. A mirror holding structure characterized by being in contact with the back surface.
