Abstract
A helicoid ring and a focusing actuation ring are movably arranged on an inner periphery and an outer periphery of a stationary lens barrel which supports a focusing movable lens assembly, respectively. The helicoid ring and the focusing actuation ring have gears which are operatively connected to each other by means of a pinion which is rotatably supported by the stationary lens barrel and which extends through an opening formed in the stationary lens barrel so that the pinion comes into engagement with the gears of the helicoid ring and the gears of the focusing actuation ring on the inside and outside, of the stationary lens barrel.
