An attenuation power control mechanism which changes opening of orifices 46, 47 of a piston 25 fitted into a cylinder 22 includes first and second valve plates 37, 38, and first and second coils 44, 45 which generate magnetic fields, whereby the first and second valve plates 37, 38 are deformed by the magnetic fields generated by the first and second coils 44, 45 to change the opening of the orifices 46, 47, so that the attenuation power of the damper can be controlled arbitrarily. At this time, the first valve plate 37 is deformed by the corresponding first coil 44, and the second valve plate 38 is deformed by the corresponding second coil 45.
