Patent ID: 7958964

Claim:
A power steering system for a vehicle, comprising: a steering shaft, said steering shaft having a rear end connected with a steering handle and an axis that is inclined forwardly downwards; and an electric motor, said electric motor being disposed with an axis orthogonal to a plane containing the axis of said steering shaft, said electric motor applying a steering force to a steering wheel or wheels according to an operational torque exerted on the steering handle, wherein said steering shaft is rotatably supported on a support case, a straight line extending vertically upward from a rear end in a non-operative state of an operating pedal disposed on a lower side of the steering handle, tangent to a rear of said electric motor and intersects with a rotational locus of the steering handle at the rear end of the steering shaft, wherein a vertical line tangent to the rear of said electric motor passes in front of the rear end of the steering shaft, wherein at least a part of said electric motor is disposed on an inner side of a constant projection of said rotational locus of the steering handle, wherein said rotational locus is the outer circumference of the steering handle and the projection of the rotational locus is coaxial with the steering axis so as to project onto a plane orthogonal to the axis of said steering shaft, and wherein the rear end in a non-operative state of the operating pedal disposed on the lower side of the steering handle is disposed on an outer side of the projection of the rotational locus of the steering handle, and a lower end of said electric motor is disposed above said operating pedal.
