Abstract: PURPOSE:To prevent a cam from being used in the case of focusing and to use the cam only in the case of zooming by moving 1st and 2nd moving frames in an optical axis direction in the case of zooming, and locking the 2nd moving frame and moving only the 1st moving frame in the case of focusing. CONSTITUTION:In the case of zooming; when a movable barrel 4 is turned, the front group moving frame 2 which is prevented from being turned by an arm part 11a is extended. On the other hand, the rear group moving frame 3 coupled with the movable barrel 4 through a cam is not turned, and since a cam surface 4d keeps level at the time of collapsing, the moving frame 3 is not moved. Thus, a focal distance for wide angle is set. When the movable barrel 4 is turned further, the moving frames 2 and 3 are respectively extended by a helicoid and the cam, thereby performing zooming. The focal distance for telephoto is set. In the case of focusing; when the movable barrel 4 is turned, the moving frame 3 is not moved and only the moving frame 2 is extended by specified amount, thereby performing focusing.

Abstract: PURPOSE:To spread the usable range by providing an auxiliary spring which energizes a disk in a direction against a flow in only a region of displacing the disk corresponding to the range where an opening area of a contraction flow part is in a specific value or less. CONSTITUTION:An auxiliary spring 8, formed of a coil spring with an axial length shorter than a spring 3, is arranged concentrically to the spring 3.
