Abstract
A lens barrel includes: a fixed frame; a zoom ring rotatably held around an outer periphery of the fixed frame; a contact member; and a biasing member. The zoom ring has a first sliding surface to a fourth sliding surface. When the contact member moves on the first sliding surface, a first load is applied to the biasing member; when the contact member moves on the second sliding surface, a second load greater than the first load is applied to the biasing member; and when the contact member moves on the third sliding surface, a load which varies in a range from the first load to the second load is applied to the biasing member.
