To provide a drive device capable of suppressing vibration caused by the driving of a drive shaft.

This drive device 10 comprises the drive shaft 1 rotated by a prime mover, a pair of pinions 2 and 3 fixed to both end parts of the drive shaft 1, and a pair of fixed racks 4 and 5 engaged with the pair of pinions 2 and 3. From the position of the teeth T2 of one pinion, the position of the teeth T3 of the other pinion 3 is differentiated by an amount of 1/2 pitch (θ/2) in the circumferential direction. Also, from the position of the teeth T4 of one fixed rack 4, the position of the teeth T5 of the other fixed rack 5 is differentiated by an amount equivalent to the 1/2 pitch in the longitudinal direction.
