Abstract

PURPOSE:To provide a small motor in which the number of components is reduced and whose bearings are stably pressed in and held. CONSTITUTION:A frame main part 10 made of resin is attached to a stator 9, a shaft 12 is inserted into a through-hole at the center of a rotor 11 and, bearings 13 which support the rotation of the shaft 14 and an oil-impregnated felt 14 for supplying oil to the bearings 13 are provided. A protrusion 16 which is composed of a hollow cylinder is provided on an annular frame cover 15 made of resin so as to press and hold the bearings 13. In order to give the protrusion 16 elastisity, a slit is formed in the protrusion 16.
