Abstract:
1. A lens barrel unit, comprising: a photographic optical system; a drive force generating unit that generates a drive force with which the photographic optical system is caused to move along a direction of an optical axis of the photographic optical system; a drive mechanism that moves the photographic optical system with the drive force received from the drive force generating unit; an image-capturing element mounting portion on which an image-capturing element that captures an image obtained through the photographic optical system is mounted; a vibration detection device that detects vibration, and is disposed in a space defined between an outer perimeter of the lens barrel unit and an outer perimeter of the image-capturing element mounting portion in a direction perpendicular to the optical axis, with the outer perimeter of the lens barrel unit being larger than the outer perimeter of the image-capturing element mounting portion; and an end member that is provided transverse to the optical axis at an end of the lens barrel unit toward the image-capturing element, the end member having a portion with a flat plate shape with a surface of the portion with the flat plate shape facing toward the image-capturing element, wherein
