ABSTRACT:
This invention is directed to a magnet-retaining structure for a motor, which comprises a cylindrical casing, two semicircular magnets inserted in the cylinderical casing, a resilient retainer whose resilient force fixes the semicircular magnets to the inner surface of the casing, and a coupler provided with brushes. Owing to the construction, the magnet-retaining structure permits simplification of the manufacture of component parts of the motor, facilitates the work of final assembly of the motor, and prevents the resilient retainer from dislocation and the magnets from displacement in the axial direction.
