PROBLEM TO BE SOLVED: To provide a focus position adjusting mechanism for a camera provided with a lens shutter, capable of adjusting the initial position of a focusing lens causing a solid difference in manufacture with a simple configuration. SOLUTION: The screw part 11a of a lens frame 11 is screwed in the screw part 12b of a guide barrel 12, this guide barrel 12 is pressed by a pressing plate 13 from above and the lens frame 11 is pressed by coil springs 9 and 10 from below, so that when the rotation of a motor 16 is transmitted with a gear 17 and the tooth part 12a of the guide part 12, the lens frame 11 is guided by columns 1b and 1c, to be vertically moved for focusing. The solid difference at the initial position of the lens frame 11 is adjusted in such a manner that a base plate 1 is rotated and moved in an optical axis direction by the screwing relation between screw parts 18a and 1d. |
