Japanese Patent JP7401226
Kind Code:
B2
Abstract:
To provide a lens barrel that can be easily assembled and has a high optical performance.SOLUTION: A lens barrel 10 comprises: a main guide bar 130 that guides a focus lens frame 220 in an optical axis direction; a first stationary lens frame 120 that holds one end of the main guide bar 130; a bearing 400 that holds the other end of the main guide bar 130; and a second stationary lens frame 320 that holds the bearing 400 movably between a first position and a second position. When the bearing 400 is at the first position, the same is regulated by the second stationary lens frame 320 from moving in a plane direction orthogonal to the optical axis direction, and when the bearing is at the second position, the same is held by the second stationary lens frame 320 movably in the plane direction orthogonal to the optical axis direction.SELECTED DRAWING: Figure 5
