Abstract
An electric motor used in an electric type power steering apparatus and the like, wherein a magnetic field unit outer casing 14 for encasing a magnetic field unit 7 comprising magnets 5 and an armature 6, is formed integral and concentric with a motor yoke 3, and a power supply unit outer casing 15 for encasing a commutator 22 and brushes 27 of a power supply unit 8, having a protruding portion 15a protruding from an axially concentric outer peripheral face thereof arranged eccentric to the magnetic field unit outer casing 14, is formed integral with the motor yoke 3. As a result, the influence of shock from the outside is suppressed, and accommodating space for the power supply unit ensured, so that long motor life is possible.
