Abstract
A lens barrel includes a lens frame, a guide shaft, a lead screw, a nut, and a biasing spring. The guide shaft is inserted into the lens frame. The nut is threaded onto the lead screw. The biasing member biases the lens frame toward the nut. The lens frame includes a first bearing component having a first insertion hole and a second bearing component having a second insertion hole. The guide shaft hits an inner peripheral face of the first insertion hole at a first and second contact point, and hits an inner peripheral face of the second insertion hole at a third and fourth contact point. The first and second contact points are disposed on opposing side of the third and fourth contact points using as a reference a parallel plane which extends along the direction of an optical axis and passes through a guide axis.
