A linear-rotary actuator includes a base, a first linear motor, a second linear motor, a linear rail, and a ball screw. The first and second linear motors are disposed on the base and respectively have a coil assembly and a magnet backplane. The linear rail is located on the base. The ball screw includes a screw and a nut, wherein the screw is connected to the first linear motor, and the nut is connected to the second linear motor. When the screw and the nut are driven by the first and second linear motors to move along the linear rail in a synchronized manner, the linear-rotary actuator provides linear motion output. When the nut is driven by the second linear motor to move along the linear rail in an asynchronous manner with respect to the screw, the linear-rotary actuator provides rotary motion output.

To provide a rotary actuator vibration control mechanism that both reduces vibration during operation and contributes to simplifying the overall structure. In this rotary actuator vibration control mechanism, a continuous shock absorbing member that is integrally formed together with a stopper and an engagement means is laid out in a rotary actuator comprising the following: a case; a rotor that is disposed inside said case and swings back and forth; an output shaft that supports said rotor and outputs the force of the swinging thereof to the outside; the aforementioned stopper, which prescribes the movement path of the rotor inside the case; and the aforementioned engagement means, which engages with an externally attached device disposed outside the case. The shock absorbing member is designed such that the stopper is formed by the molded body that forms the shock absorbing member, and is also designed so as to cover the entire engagement means. The shock absorbing member may be designed such that an integral molded body covers contact parts of both the stopper and the engagement means in a continuous manner, or may be changed to a design in which both are integrally formed by the shock absorbing member.
