A motor having a motor casing rotatably supporting a motor shaft is mounted in respect to a base so as to permit adjustment of the angular relation of the axis of the motor shaft in respect to the base by providing first and second spaced apart fulcrum-defining abutments extending from the motor casing and engageable with the base along a first straight line which is spaced from the axis of the motor shaft, coil springs urging the fulcrum-defining abutments against the base so that the motor casing and shaft are angularly displaceable about the first straight line in respect to the base, a leaf spring disposed between the motor casing and base and having an angled portion for urging the motor casing and shaft angularly relative to the base in one direction, a pin with a threaded bore extending from the motor casing at a location which is spaced, in a direction opposite to the first straight line, from a second straight line passing through the axis of the motor shaft parallel to the first straight line, and an adjusting screw received in the threaded bore and engaging the base for adjustably determining the angular position relative to the base to which the motor casing and shaft are urged by the leaf spring.
