PROBLEM TO BE SOLVED: To provide a lens barrel whose assembly man hour can be greatly reduced by eliminating the need for making the phase of a rotatory ring support means match the phase of rotatory ring and by fixing the rotary ring support means to an outer frame means in a unit form without using screws. SOLUTION: A protrusion 48 is formed on an outer frame 42 and engaged in the space 54 of a ring base 52. Further, a stopper protrusion 58 is formed on the ring base 52 and engaged in the stopper space 62 of a fixed frame 46. Thus, a focus ring unit 44 can be fixed by simply fixing the fixed frame 46 to the outer frame 42. COPYRIGHT: (C)2007,JPO&INPIT
