ABSTRACT:
A steering control apparatus in which a steering shaft coupled to a steering wheel is mechanically separated from a turning mechanism to turn a turning wheel, a steering angle of the steering wheel is detected, and the turning mechanism turns the turning wheel by a turning angle corresponding to the steering angle, includes a hypercycloidal mechanism including an external tooth gear revolving in a housing according to rotation of the steering wheel, an Oldham coupling mechanism to extract only a self-rotating movement in a rotation movement of the external tooth gear as a self-rotating movement of a rotation disk, and a rotation regulating mechanism by engagement between a groove formed in the rotation disk and a projection projecting from the housing. Then, a compact mechanical steering angle regulating mechanism is provided in which an allowable rotation range of the steering wheel is made ±180 degrees or more, and a low output and low capacity motor is used, and reduction in size and in cost of the apparatus is realized.
