PROBLEM TO BE SOLVED: To provide a drive device capable of eliminating the necessity of putting the tooth flanks of two gears together with high precision and keeping the position relation of the tooth flanks ready for the wear of the gears with age. SOLUTION: In the drive device provided with the two helical gears 2 and 3 coaxially 1, a helical gear 2 is fixed to the axis 1, and the other gear 3 is restrained in its rotation direction. The helical gear 3 whose rotation direction is restrained is provided slidably in the thrust direction. The helical gear 3 is pressurized in the thrust direction. The direction of the pressurization is opposite to the direction of the driving force applied to the helical gear 3. COPYRIGHT: (C)2004,JPO
