Abstract:
An actuator has a first yoke plate, a second yoke plate, magnets, coils, a haptic feel providing member, and a coil fixing member. The first yoke plate and the second yoke plate each assume a plate-like shape having a generally square outline, and are provided approximately parallel with each other. The magnets are fixed to that surface of the first yoke plate which is opposed to the second yoke plate. The coils are provided movably between the magnets and the second yoke and are fixed to the coil fixing member so as to form a unitary body together. Electromagnetic forces that are generated in magnetic fields of the magnets act on the coils, whereby the haptic feel providing member that is supported by the coil fixing member is moved.
