Abstract: An electrical rotating machine is provided with a salient-pole rotor, which is composed of magnetic field pole bodies integrally formed with a shaft and pole shoes constituting magnetic field pole heads. Each pole shoe is fixedly joined on the corresponding one of the magnetic field pole bodies with a plurality of bolts. Each pole shoe or its corresponding magnetic field pole body is provided with at least one protrusion or recess for restricting a conically-shaped compression domain in a compression domain that occurs in the pole shoe when the pole shoe is joined on the corresponding magnetic field pole body with the bolts.
