1. A unit with shake correction function comprising:
a movable body, provided with a disposition space for an optical module;
a fixed body;
a rolling support mechanism, configured to support the movable body to be rotatable about an optical axis of the optical module relative to the fixed body; and
a rolling drive mechanism, configured to revolve the movable body about the optical axis,
wherein the rolling drive mechanism comprises:
a driving coil, mounted on one of the movable body and the fixed body; and
a driving magnet, mounted on the other of the movable body and the fixed body; and
wherein the driving coil and the driving magnet face each other in a direction of the optical axis, and are arranged on an outer side of a radial direction with the optical axis at a center, relative to the disposition space;
wherein the rolling drive mechanism overlaps the movable body when viewed from the radial direction;
wherein
the optical module comprises a magnet and a coil; and
a center of the magnet in the direction of the optical axis and a center of the driving magnet in the direction of the optical axis overlap one another when viewed from the radial direction.
