Lens barrel structure and image capture apparatus

An image capture apparatus comprising a lens barrel structure that includes a lens, and an image capture device that captures a subject image having led by the lens, the lens barrel structure including:

• a base;
• a lens barrel provided on the base;
• a lens moving mechanism provided in the lens barrel, the lens moving mechanism supporting a lens movably in an optical axis direction thereof and being supplied with a rotational drive force thereby to move the lens in the optical axis direction;
• a lens drive mechanism provided to the base, the lens drive mechanism supplying the lens moving mechanism with the rotational drive force, and including a motor including an output shaft, a drive gear provided to the output shaft, and a gear train that meshes with the drive gear to supply motive power of the motor to the lens moving mechanism;
• and
• a detecting mechanism that detects a rotation speed of the motor,
• wherein
• the detecting mechanism includes a sensing plate that is provided to the output shaft and that rotates integrally with the output shaft, and a detector that detects rotation of the sensing plate;
• and
• of gears included in the gear train, a first gear to mesh with the drive gear is supported in a cantilever support manner on the side of the base.
