Abstract
An electric rotating machine does not require management of the gap between a fan guide at a small-diameter portion and a fan fixing portion and can suppress the manufacturing and maintenance costs from increasing. An electric rotating machine is provided with a small-diameter portion fan guide that extends both in a circumferential direction and in an axial direction in such a way as to be provided a space in the radial-direction outer side of a small-diameter portion that is a portion of an extending axle portion, of a rotation axle, that extends in the axial direction from a rotor, the portion being at an axial-direction departing side than a fan fixing portion to which an axial-flow fan is fixed and in such a way that the small-diameter portion fan guide is disposed to be provided a space with the fan fixing portion in the axial direction.
