PROBLEM TO BE SOLVED: To provide a motor which can suppress the deformation due to press-fitting of the inner circumference of a shaft within a storage range where a stored member is stored. SOLUTION: A motor is equipped with a rotor core 11 which has a center hole 11a, a roughly cylindrical shaft 7 which is press-fitted in the center hole 11a, and a rod member (stored member) which is arranged, in the storage range X2 lying axially upon the side of axial one end of the rotor core 11, within the shaft 7. Internal thread 7a is made in the storage range X2 within the shaft 7. The rod member is provided rotatably and axially shiftably to a stator, and it has external thread to be screwed in the internal thread 7a. The shaft 7 is press-fitted, within the press-fitting range X1 on the side of the other end excluding the storage range X2, into the center hole 11a of the rotor core 11. COPYRIGHT: (C)2006,JPO&NCIPI
