PROBLEM TO BE SOLVED: To provide a size-reduced and structure-simplified motor which performs rotating action and axial shifting action. SOLUTION: A first coil 2 and a first permanent magnet 3 are fixed to a magnetic material 1 on a fixing side, and a second coil 5 and a second permanent magnet 6 are fixed to a magnetic material 4 on the shifting side, and between a first constitution composed of the first coil 2 and a second constitution composed of the second coil 5 and the first permanent magnet 3, a rotary synchronous motor is constituted in the first constitution and the magnetic material 4 on the shifting side is rotated, and a linear synchronous motor is constituted in the second constitution and the magnetic material 4 on shifting side is linearly shifted in its axial direction.
