Abstract
An electromagnetic drive device includes a coil frame with a hollow tubular shape, a magnet rotor disposed in the coil frame to be rotatable through a rotational shaft, a transmission arm attached to the rotational shaft for outputting a rotation of the magnet rotor to an outside, and a coil wound around an outer periphery of the coil frame. The tubular coil frame is divided laterally in a direction perpendicular to the rotational shaft, and is formed of two bobbin members. The transmission arm is attached to the rotational shaft in a state approximately perpendicular to the rotational shaft. An opening is provided in one of the bobbin members in a peripheral side surface at a location different from a connection surface contacting the other of the bobbin members, so that the transmission arm protrudes to an outside of the coil frame through the opening.
