Abstract

See full text

A lens barrel enables to improve the optical performance thereof while realizing size reduction, structure simplification, and cost reduction in the lens barrel. A second group holding frame 21, in a collapsed state, is rotated with respect to the second group base plate 22 in a direction retracting from the optical axis A, and in a photographing state, is rotated toward the optical axis A. A compression spring 23 regulates an optical axis A direction position of the second group holding frame 21 with respect to the second group base plate 22 by urging, in the optical axis A direction, a portion of the second group holding frame 21. An engaging pin 22d and an engaging groove 21e, in the photographing state, regulate the optical axis A direction position of the second group holding frame 21 with respect to the second group base plate 22.
