Abstract: A lens barrel includes: a variable-power optical system including a focus lens group; a focus actuator configured to move the focus lens group supported by a support forward or backward in a direction of the optical axis to change a shooting distance; and a moving unit configured to, in response to receiving a driving force for changing a zoom magnification, move a position of the focus lens group in the direction of the optical axis to a position corresponding to the changed zoom magnification. The moving unit is configured to move the focus lens group in the direction of the optical axis by the driving force such that a change in a shooting distance due to a change in the zoom magnification is within a predetermined tolerance when the focus lens group is at a position corresponding to the minimum shooting distance, at every zoom magnification.

Abstract: In an embedded magnet motor, radial magnets and first inclined magnets form north poles. The radial magnets and second inclined magnets form south poles. Core sheets each include preformed radial accommodating slots the number of which is expressed by P/2. Some of the preformed radial accommodating slots are short slots and the rest are long slots. The short slots are located at some parts of each radial accommodating slot along the axial direction. Radially inner ends of the short slots restrict the radial magnets from moving radially inward.
