- 1 - Abstract: A plurality of permanent magnets are disposed with gaps between adjacent magnets along the inner peripheral surface of a yoke of a stator for a magneto D.C. motor. In gaps between adjacent magnets there are provided retainers each of which is made of an elastic material and consists of one surface fixed on the yoke, two surfaces extending in the central axial direction of the D.C. motor along side surfaces of the magnets opposite each other on the inner peripheral surface of the yoke and two end portions connecting these two surfaces. Those two surfaces and end portions are kept in contact with the permanent magnet from three directions, namely from each of the side surfaces of the permanent magnet and from each of the end surfaces of the magnets adjacent each side surface extending in the central axial direction whereby the permanent magnets are pressed and clamped to be secured to the yoke.
