PURPOSE: To provide an inexpensive optical component connecting device by which the fixing of the positional relation of two optical parts is easily and also accurately performed by a simple constitution. CONSTITUTION: A positioning projected part 14 is provided together with a screw part 13 at the outer peripheral part of a lens barrel part 10 to hold a lens 11. A screw part 22 capable of being screwed with the screw part 13 on the side of the lens barrel part 10 is provided on the inner wall surface of a holding part 20 at which a CCD package 21 is attached, and plural positioning recessed parts 23 are provided at the top part of the screw part 22. After the lens barrel part 10 is connected with the holding part 20 by the screw parts 13 and 22 by rotating and operating the clamping part 12 of the lens barrel 10, it is gradually rotated, so that the projected part 14 is positioned to the recessed part 23 so as to be deviated one by one. When rotating operation is stopped at an optimum focusing position, the projected part 14 is made in an engaged state with the recessed part 23. The projected part 14 does not fall off from the recessed part 23 in this state unless strong force is applied, so that the engaged state is held. |
