Abstract
A bearing member 13 is provided on a main body 12 of a motor 10 so as to support a base end portion of a driving shaft 11. A cylindrical holder 23 is integrally formed with the main body so as to surround the bearing member. A lateral bearing member 21 is disposed in the cylindrical holder so as to adjacent to the bearing member on a side of a distal end of the driving shaft to laterally support the driving shaft. A spring member 22 is disposed in the cylindrical holder so as to extend along an inner peripheral face of the cylindrical holder and such that one tip portion thereof urges a part of an outer peripheral face of the lateral bearing member in a direction perpendicular to the driving shaft.
