The present driving apparatus comprises a torque motor 10 as a driving source, and a gear train which transmits rotation of a motor shaft 1 of the torque motor 10 to a driven shaft 13, wherein the gear train comprises a non-circular driving gear 11 which is attached to the motor shaft 1 and a non-circular driven gear 12 which is attached to the driven shaft 13 and engaged with the non-circular driving gear 11. When the motor shaft 1 rotates by supplying electric power to the torque motor 10, the rotation is transmitted to the non-circular driven gear 12 via the non-circular driving gear 11, so that the driven shaft rotates. Here, the torque of the torque motor 10 is transmitted to the driven gear while it is increased or decreased in accordance with rotating positions. In this manner, the driving apparatus with a torque motor can provide desired torque at any rotating positions.
