Abstract

PURPOSE:To decrease the number of constituting parts, and also, to make the titled device small in size and light in weight, by providing a power transfer member between one and the other lens frames, so that it can be displaced and moved together with these lens frames. CONSTITUTION:When one lens frame 50 is rotated in one direction, the left end part of a power transfer member 54 is transferred out in the direction of the other lens frame 52 from the lens frame 50, while being supported by a guide part 68, and by accompanying it, the left end part of the power transfer member 54 winds round the other lens frame 52, while being supported by a guide part 70. In such a case, the power transfer member 54 which is supported by not only the guide parts 68, 70 but guide parts 64, 66 executes efficiently a transfer of turning force from one lens frame 50 to the other lens frame 52. In such a way, the power transfer mechanism is simplified, the number of constituting parts is decreased, and the device can be made light in weight and/or small in size.
