PROBLEM TO BE SOLVED: To provide a method of assembling a stepping motor and a method of assembling a train wheel for a pointer that accurately half-rotates a rotor at a first drive pulse, and accurately detects the rotation position of a pointer wheel. SOLUTION: Corresponding to a position to which the rotor 17c is attached and the direction of the magnetic pole of the rotor 17c, a bottom board 14 as a holding member having a coil 17a and stator 17b is mounted to an assembling fixture 50 having a previously magnetized magnet 53 for position regulation, and the rotor 17c is arranged in a rotor hole 17g of the stator 17b mounted to the bottom board 14. At this time, the magnetism of the rotor 17c can be kept at an attaching position corresponding to the magnetism of the magnet 53 for position regulation by the magnetic force of the magnet 53 for position regulation disposed in the assembling fixture 50.
