Abstract
A structure reliably secures a stepping motor to a circuit board. The stepping motor has an axially protruding boss portion accommodating a shaft in the inside, which boss portion is provided to be snapped into a circuit board, axially protruding current conducting terminal pins that are made so as to be soldered to the circuit board, and securing pins not functioning as electrodes, which securing pins are made so as to be soldered to the circuit board and are arranged in a position whereby they sandwich the boss portion between themselves and the current conducting terminal pins.

A stepping motor comprising:
- an axially protruding boss portion accommodating a rotation shaft in the inside, which boss portion is provided to be snapped into a circuit board;
- axially protruding current conducting terminal pins that are made so as to be soldered to the circuit board;
- securing pins that do not function as electrodes, are made so as to be soldered to the circuit board and are arranged at positions whereby they sandwich the boss portion between themselves and the current conducting terminal pins;
- a front plate facing the circuit board;
- and
- a stator disposed behind the front plate,
- wherein the front plate is equipped with the current conducting terminal pins, the boss portion, and the securing pins.
