COMPONENT FIXING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a component fixing structure which has a simple and inexpensive configuration to allow a component to be easily and reliably fixed in a short time.SOLUTION: A fixing structure for an optical member includes: a coil spring 82 having a shaft part insertion hole; a clip member 81 including a shaft part 83 freely slidably placed in the shaft part insertion hole, a first convex portion 84 provided on the shaft part 83 and having a first contact surface 84a with which the coil spring 82 is brought into contact, a second convex portion 85 having a second contact surface 85a facing the first contact surface 84a, and a slit 86 making the second convex portion 85 elastically deformable into a large-diameter shape and a small-diameter shape; a lens holder 51 which includes a clip insertion hole 51h which includes a placement surface having a lens 52 placed thereon and a support surface having the second contact surface 85a placed thereon and allows the second convex portion 85 to pass therethrough with the small-diameter shape; and a lens retainer 53 which includes a clip insertion hole 53h which includes an urging surface having the coil spring 82 placed thereon and a pressing surface being in contact with the lens 52 placed on the lens holder 51 and allows the second convex portion 85 to pass therethrough.
