PROBLEM TO BE SOLVED: To provide a stepping motor so constructed that short circuiting does not occur between terminal pins even if the motor is reduced in size. SOLUTION: Two pairs of terminal pins (18 and 19, and 25 and 26) shifted by 90 degrees from each other are protruded to the outside of a case 20 through two cut portions 20a and 20b formed in the case 20. An end of a coil 17 or 24 wound around a coil bobbin is wound on and soldered to each of these terminal pins. The terminal pin pairs are both so constructed that they are integrally formed on two stators disposed at a distance from each other and a wide distance is provided between terminal pins in the direction of rotor shaft. The pairs of the terminal pins are protruded to the outside of the case 20 so that they are shifted by a certain angle. Therefore, the terminal pins can be so disposed that a wide distance is provided between them even if the stepping motor is reduced in size. As a result, short-circuiting can be prevented when coil ends are soldered to these terminal pins and the soldering workability is enhanced. COPYRIGHT: (C)2006,JPO&NCIPI
