Abstract

본 발명은 투사렌즈에 나사결합되어 있는 포커싱 렌즈가 투사렌즈에 형성되어 있는 나사부로 부터 이탈되는 것을 방지할 수 있는 포커싱 렌즈의 이탈방지장치가 제공하기 위하여 투사렌즈(20)에 형성되어 있는 나사부(22)에 나사결합되는 포커싱 렌즈(24)가 상기 나사부(22)로 부터 이탈되는 것을 방지할 수 있는 포커싱 렌즈의 이탈방지장치에 있어서, 상기 나사부(22)의 뿌리부분에 형성되어 있는 불완전나사부(22a)에 삽입되어 상기 나사부(22)에 이르면 걸리는 이탈방지 링(30)을 상기 포커싱 렌즈(24)의 선단부에 결합하여 구성한 것이다.The present invention provides a screw portion formed in the projection lens 20 to provide a focusing lens separation prevention device capable of preventing the focusing lens screwed to the projection lens is separated from the screw portion formed in the projection lens ( In the focusing lens departure preventing device that can prevent the focusing lens 24 is screwed to the screw 22 to be separated from the screw 22, an incomplete screw portion formed in the root portion of the screw 22 ( 22a) is coupled to the distal end of the focusing lens 24 is coupled to the separation preventing ring 30 is inserted when the screw 22 is reached.
