<p>PROBLEM TO BE SOLVED: To provide a servo motor device for use in a radio control system, which can fit a servo horn to an output shaft in a unique position without a fitting error, and can also use a conventional servo horn fitted at an optional angular position of the output shaft.SOLUTION: An output shaft 3 of a servo motor device is provided with a sawtooth-like part 4 and a partially missing tooth part 5. The sawtooth-like part 4 is provided with projecting and recessed parts in a fixed period. The partially missing tooth part 5 is formed inside of a root circle 4a of the sawtooth-like part 4 around the rotation axis 3a. By this configuration, both a dedicated servo horn having a fitting part fitted to the output shaft 3 in a unique position and a conventional servo horn fitted to an optional angular position of the output shaft 3 can be fitted to the output shaft 3.</p> |
