A rotor for a reluctance type rotating machine includes a rotor core formed by stacking a number of annular core materials each of which includes magnetic concave and convex portions alternately formed on an outer circumference thereof and a central through hole, the rotor core having a key axially extending on an outer circumference, the rotor core being divided into a plurality of blocks, the core materials constituting one of at least three blocks having the magnetic concave and convex portions shifted by a predetermined angle in one of a rotating direction of the rotor and a direction opposite the rotating direction of the rotor relative to a center line passing the key, the core materials constituting each one of the blocks located at both ends of the one block having the magnetic concave and convex portions shifted by a predetermined angle in the other of the rotating direction of the rotor and the direction opposite the rotating direction of the rotor relative to a center line passing the key, and a rotational shaft inserted through the central hole of the rotor core, the shaft having a key groove engaging the key of the rotor core.
