摘要： A vibration apparatus, which is provided with vibration actuators with which a moving body elastically supported on a fixed body can be vibrated linearly with respect to the fixed body at a resonance frequency, has a mounting case in which multiple vibration actuators are mounted. The multiple vibration actuators oscillate at roughly the same resonance frequency, and in a manner such that the respective oscillation axis lines along the oscillation directions of the moving bodies are parallel to each other and that the center of gravity of the mounting case is interposed between the oscillation axis lines, the vibration actuators are disposed in orientations according to which the actuators excite oscillations in mutually opposite directions on the respective oscillation axis lines.

摘要： A vibration actuator includes: a fixing part including one of a coil and a magnet; a movable part including the other one of the coil and the magnet; and an elastic supporting part configured to support the movable part movably with respect to the fixing part. The movable part is configured to reciprocate with respect to the fixing part in a vibration direction through cooperation between the powered coil and the magnet. The magnet is disposed away from and radially inside the coil. The elastic supporting part has a plate-like shape in which one end of the elastic supporting part is fixed to the fixing part at the side of the movable part and the other end is fixed to the movable part, and cantilevers the movable part in such a manner that the movable part can reciprocate in the vibration direction.

摘要： An actuator includes a movable body including a cylindrical magnet portion, an immovable body including pole tooth faces and a coil, and a torsion coil spring supporting a movable body to the immovable body. The coil receives an alternating current of a frequency substantially equal to a resonance frequency of the movable body and excites the pole tooth faces to have alternately different polarities in the circumferential direction. One end of the torsion coil spring is fixed to one end of a rotary shaft of the movable body and other end is fixed to the immovable body. The torsion direction of the torsion coil spring is arranged to be coaxial with the rotary shaft. The torsion coil spring supports the movable body to enable the movable body to vibrate at the resonance frequency of the movable body.

摘要： A rotor includes a rotor core comprised of magnetic steel sheets laminated in the axial direction and a pair of end plates that are respectively provided on the axial end faces of the rotor core so as to together sandwich the rotor core in the axial direction. The rotor is rotatably disposed in an electric rotating machine with a circumferential surface of the rotor core facing a stator. At least one of the end plates is configured to have through-holes, each of which is formed so as to axially penetrate the end plate, and a pressing portion that is radially positioned on the stator side of the through-holes. The pressing portion abuts a corresponding one of the axial end faces of the rotor core and exerts an axial load on the corresponding axial end face of the rotor core by an elastic force of the end plate.

摘要： Disclosed is an actuator that realizes reciprocal rotational motion of an electric toothbrush, for example, without utilizing a drive transmission mechanism that is separate from the drive source. In the actuator, a fixed body (120) has a coil (128) that is disposed around a magnet (160) and faces the magnetic planes with different polarities within the magnet (160) at individual prescribed distances, and an outer yoke (150) that covers the outer periphery of the coil (128). The fixed body (120) rotatably supports a movable body (110), which holds the magnet (160), via a coil spring that is an elastic member (130) made from a wire. An alternating current supplying part (140) supplies an alternating current having roughly the same resonance frequency as that of the fixed body (120) to the coil (128) to cause the movable body (110) to vibrate in a reciprocal rotational motion. The coil spring that is the elastic member (130) uniformly disperses stress generated by the vibration.
