Abstract: An actuator includes drive magnets (first drive magnet and second drive magnet) and back yokes (first magnetic back yoke and second magnetic back yoke). The back yokes are each provided one to one for an associated one of the drive magnets. The associated one of the drive magnets is attached to each of the back yokes. The back yokes include at least one pair of back yokes facing each other with respect to an optical axis. Each of the at least one pair of back yokes includes a base and a yoke protrusion. An associated one of the drive magnets is attached to the base. The yoke protrusion is coupled to the base and arranged to face at least one out of two ends of the associated drive magnet in a rolling direction of a movable holder.

Abstract: In an actuator (camera driver) according to the present invention, when a movable unit is in a neutral position in which the movable unit has rotated around neither an axis nor an axis, a first synthetic vector and a second synthetic vector are directed toward an object to be driven with respect to a plane including the both axes. The first synthetic vector is defined by synthesizing together two first vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of first driving magnets and the pair of magnetic yokes. The second synthetic vector is defined by synthesizing together two second vectors, pointing toward a pair of magnetic yokes, of magnetic attraction forces between a pair of second driving magnets and the pair of magnetic yokes.

Abstract: An electromagnetic relay includes a fixed contact, a movable contact, a movable contactor, a shaft, first and second excitation coils, a fixed element, and first and second movable elements. The movable contact is movable from a closed position to an open position. The movable contact contacts to the fixed contact when the movable contact is positioned at the closed position. The movable contact is away from the fixed contact when the movable contact is positioned at the open position. The movable contactor includes the movable contact. The shaft is configured to move the movable contactor in one direction. The first movable element is movable to a first position and a second position. The first movable element is positioned at the first position when the first movable element is attracted by the fixed element due to the first excitation coil.
