Abstract
A rotor of the present invention includes: a tube-shaped rotor core which is formed by stacking disc-shaped electromagnetic steel plates in layers, which is fixed to a rotary axis and which includes a plurality of through holes that are spaced in a circumferential direction of the rotor core and that penetrate along an axis direction of the rotary axis; and tie rods which are respectively press-fitted into the through holes, where the tie rods are formed with a plurality of rod-shaped members which are arranged in series along the axis direction, and there is no possibility that the positions of slits in the axis direction between the rod-shaped members adjacent in the axis direction coincide with each other in all the tie rods.
