Abstract
A magnetic geared rotating machine includes: a stator; a rotor including a plurality of rotor magnets; and a magnetic pole piece rotor including a plurality of magnetic pole pieces each disposed at a radial position between the stator and the rotor. Each of the magnetic pole pieces has a magnetic pole piece end face facing one side in an axial direction. Each of the rotor magnets has a rotor magnet end face facing the one side. At least part of the magnetic pole piece end face is located on the other side in the axial direction relative to the rotor magnet end face, or a finger end face, of each of a plurality of fingers, facing the one side is located on the other side relative to a tooth end face, of a tooth of the stator, facing the one side, the plurality of fingers being configured to hold therebetween a stator magnet disposed on the tooth from both sides in a circumferential direction.
