To obtain a motor in which lubricant is secured permanently and smooth rotation is guaranteed for a long term while reducing the rotation sound over a long term.

A boss 28 is formed on the bottom face of a case body 12 and the forward end part of a supporting shaft 16 is press fitted in a recess existing in the center of the boss 28 thus securing the supporting shaft 16. An annular wall part 30 is formed to project upward at the outer circumferential part of the boss 28. An oil storing part exists in the wall part 30 and lubricant is stored therein. A rotor 18 having permanent magnets 20 arranged on the outer circumferential side is supported by the supporting shaft 16 while engaging with the supporting shaft 16 rotatably.
