A suspension system is provided to execute a control for avoiding a state in which an operation of an electric motor which is a power source of an electromagnetic actuator is kept halted at a certain operational position while the motor is generating a motor force. In some cases one or more of these genes are native to the host organism and the remainder are provided from transgenes. The braking force transmission means include two transfer levers, whose two ends are connected without play to the mount and the brake, respectively, by respective pivot points, which are radially spaced apart from their respective axes of rotation.
