を特徴とするレンズ固定装置。 The lens barrel or holding frame that holds the lens has a locking part for the lens holding ring on the outer periphery near one end, and the lens barrel or holding frame is inserted from one end of the lens barrel or the holding frame to connect with the locking part. In a lens fixing device comprising a retaining ring made of a flexible elastic member having an engageable locking piece at one end and a pressing part for pressing the lens at the other end, the lens is attached to the lens barrel or holding frame. A lens fixing device characterized in that after insertion, an elastic force generated by engaging a retaining ring with a locking portion acts on the lens to fix it to a lens barrel or a holding frame.
