Abstract:
A lens driving device includes a lens, a moving member that supports the lens, a stationary member that movably supports the moving member, a pitch drive mechanism that drives the moving member in the pitch correction direction, and a yaw drive mechanism that drives in the yaw correction direction. The pitch drive mechanism has first and second magnets provided to the stationary member, and first and second coils provided to the moving member. The yaw drive mechanism has a third magnet provided to the stationary member, and a third coil provided to the moving member. The first and second coils are arranged on opposite sides of the lens when viewed in a third direction that is perpendicular to the pitch and yaw correction directions, and the third coil is arranged on the same side as the first coil with respect to the lens when viewed in the third direction.
