Abstract
A power steering driving deviceincludes an input shaftprovided with a serrationand connected to an input mechanismlinked to a steering handle, an output shaftprovided with a serrationand connected to an output mechanismlinked to a vehicle wheel, and a torsion barthat connects the input shaftand the output shaftcoaxially. The serrationof the input shaftand the serrationof the output shaftare formed such that a ratio between the respective numbers of teeth thereof is a decimal, and to specify a relative rotation position of the input shaftand the output shaftrelative to the input mechanismand the output mechanism, a tooth on the serrationof the input shaftand a tooth on the serrationof the output shafthaving a relative position deviation angle about an identical central axis which is equal to or smaller than an allowable value are selected as reference teeth.
