。[Claims for Utility Model Registration] (1) A gear train including a drive gear, an output shaft, and a running gear that meshes only during running rotation and transmits the rotation of the drive gear to the output shaft side; In a drive unit comprising a supporting gearbox and a power spring installed between the drive gear and the gearbox and storing spring force by rotation of the drive gear, the output shaft is meshed with a coaxial driven pinion. A long hole is provided so that the mating gear can be moved in the vertical direction around it, and supported by a gearbox, and the driving gear is engaged with the output shaft in its movement direction, so that the driving gear is moved by the vertical movement of the output shaft. A drive unit that rotates. (2) The drive unit according to claim 1, wherein the power spring is a torsion coil spring.
