LENS-GUIDING DEVICE, LENS-MOVING DEVICE, AND IMAGING DEVICE

Provided are a lens-guiding device, a lens-moving device, and an imaging device, capable of accurately positioning a lens frame regardless of the orientation of a photography direction or the like. According to the present invention, a first rail 41 supports a first rolling body 45 such that the first rolling body 45 can roll in a first direction that is parallel to the optical axis of a first focusing lens. A second rail 42 supports a second rolling body 46 such that the second rolling body 46 can roll in the first direction. An impelling mechanism 47 supports the first rolling body 45 such that the first rolling body 45 can move in the first direction and impels the first rolling body 45 toward the first rail 41. A third rail 43 is arranged parallel to the second rail 42. The third rail43 supports the second rolling body 46 such that the second rolling body 46 can move in the first direction. The first rolling body 45 and the second rolling body 46 move/guide the first rail 41 and the second rail 42 in the
