In order to provide a multi-degree-of-freedom drive mechanism which is capable of preventing a malfunction with a simple structure, the multi-degree-of-freedom drive mechanism includes at least two first and second actuators which generate lengthwise resonance in drive shafts by means of electro-mechanical transducers in a state that driven members are frictionally engaged with the drive shafts to which the electro-mechanical transducers are fixed at its one end, respectively, so as to be capable of moving the driven members along the drive shafts. The other end of the drive shaft of the second actuator is fixed to the driven member of the first actuator 10 directly or via another actuator, and the first and second actuators are composed so that resonating frequencies of their drive shafts are different from each other.
