Abstract

A lens barrel includes: a first ring; a second ring that switches between a first position and a second position by sliding in an optical axis direction; a plurality of biasing mechanisms that are provided on one of the first ring and the second ring, and providing adjustable biasing force in a radial direction; and a locking portion provided on the other of the first ring and the second ring on which the plurality of biasing mechanisms are not provided. The plurality of biasing mechanisms each include an elastic component having a contact portion and a biasing component that biases the elastic component. The first ring and the second ring are integrally rotatable when the contact portion contacts the locking portion which opposes the contact portion when the second ring is at the second position.
