An output shaft support structure comprising:
- an output shaft;
- and
- a supporting body configured to support the output shaft, wherein
- the output shaft includes:
- a rotating shaft;
- a first rolling bearing fixed to one end section of the rotating shaft;
- a second rolling bearing fixed to another end section of the rotating shaft;
- and
- a gear including a boss section fixed to the rotating shaft, and wherein
- for a predetermined period, the boss section of the gear contacts the second rolling bearing, and a lower end of the rotating shaft is always separated from the supporting body.
