The lens barrel includes a first motor (56) that drives a third front lens group-holding frame (24B) by first magnets (56A) provided on the third front lens group-holding frame (24B) and a first coil (56C), and a second motor (58) that drives a fourth lens group-movable holding frame (26B) by second coils (58A) provided on the fourth lens group-movable holding frame (26B) and second magnets (58B) provided on a fourth lens group base-holding frame (26A) fixed to the stationary barrel (12) and the cam barrel (14). The third front lens group-holding frame (24B) is fixed by a magnetic force between the first magnets (56A) and inner and outer yokes (58C, 58D) provided on the fourth lens group base-holding frame (26A) in a case where the application of current to the first coil (56C) is stopped."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lens barrel and imaging device","description":"There are provided a lens barrel and an imaging device that can fix a movable member to a stationary frame without providing a member for fixing the movable member.
