Electrical servo steering device for moving in compliance with steering force includes a rack-and-pinion mechanism, a ball-and-nut spindle mechanism and an electric motor.

摘要

A rack-and-pinion mechanism (5) moves in compliance with steering force. A ball-and-nut spindle mechanism has a ball nut coaxial to the rack-and-pinion mechanism. A first cogwheel (21) is attached to an output shaft on an electric motor (6). A second cogwheel (22) is fitted coaxially to the axial line of the rack-and-pinion mechanism that inclines to the axial line of the electric motor.
