PURPOSE: To electrically connect a motor to a printed board stably and accurately and secure a case body stably and accurately by projecting an outside connection terminal which is formed on a terminal holding section which is integrally formed with a flange of a coil-wound resin-made bobbin and a fixation piece which is formed by cutting up a part of the case body, in the axial direction outside of the body case.

CONSTITUTION: Integrally with downside outer parts of flange sections 2A, 2B of resin-made bobbins 1A, 1B around which coils to allow an exciting signal to run in are to be wound, terminal holding sections 3A, 3b are formed. Then, terminals 4A, 4B are secured to the terminal holding sections 3A, 3B and coil terminal connecting sections are bent outward and the other ends are projected downward and thereby outside connection terminals 41A, 41B are formed. In a cover 9B of a case body, a fixation piece 93 is integrally formed with the cover 9B by cutting up a part of the cover 9B. By this method, a stepping motor 10 can be secured on a printed board stably with the fixation piece 93 and can be surely connected electrically by means of the outside terminals 41A, 41B.
