PROBLEM TO BE SOLVED: To provide a lens feed mechanism which is advantageous for achieving downsizing, and to provide a lens barrel and an imaging apparatus. SOLUTION: An internal thread member 1506 is moved across an external thread section 1502A of an external thread member 1502 and a point 1502C of a shank 1502B adjacent to an external thread member 1502A. A movable lens moves back and forth linearly in an optical axis direction following the movement of the internal thread member 1506. The shank 1502B is provided with a slant suppressing section 1510. The slant suppressing section 1510 suppresses the slant of the internal thread member 1506 on the point 1502C of the shank 1502B adjacent to the external thread section 1502A within the range where the external thread section 1502A and the internal thread section 1506A can be screwed again by the rotation of the external thread member 1502 in a state in which the internal thread member 1506A released of screwing to the external thread section 1502A exists on the point 1502C.
