Abstract: PROBLEM TO BE SOLVED: To provide a lens barrel and an imaging apparatus that are advantageous to securely preventing an abnormal sound and vibrations from being generated while smoothly moving a movable lens along an optical axis.
SOLUTION: A coil spring 2808 is wound around a guide shaft 28A and has its one end engaged with a large-diameter part 5402 of a 1st guide shaft insertion part 50 to be locked to a 3-group lens frame 1802. The large-diameter part 5402 is formed to an external diameter corresponding to the internal diameter of the coil spring 2808 and a small-diameter part 5404 is formed having a smaller external diameter than the large-diameter part 5402, so its one end is never displaced at right angles to the axis because of the large-diameter part 5402 and a gap is therefore secured between an inner peripheral part of the coil spring 2808 and an outer peripheral surface of the small-diameter part 5404.

Abstract: PROBLEM TO BE SOLVED: To protect a movement of a part in the specified direction in fixing it with a screw. SOLUTION: A rectangular shaped projection 3c of a rear mirror tube 3 is equipped in both sides of a through hole 3b opposing to the vertical direction (X direction). When a screw 4 is inserted into this through hole 3b and a fixed hole (not shown in the figure) of an intermediate mirror tube passing through this and made to rotate, a take around force F1 caused by a rotation of the screw 4 works against the projection 3c by the initial contact of the lower part of a head 4a of the screw 4 with the projection 3c. The take around force F1 works strongly in the vertical direction to the opposite direction, that is Y direction, of the projection 3c and hardly works to the X direction because the projection 3c is formed opposite to the through hole 3b. By this reason, it becomes possible to fix both mirror cylinders with the screw 4 without changing a position of the rear mirror cylinder 3 in the X direction to the middle mirror cylinder 2.
