<p>PURPOSE:To nullify a load on a handle to facilitate operation of a car with the same sense as ordinary steering sense by releasing a locking action carried out by means of the lever of a ring gear when a mechanism including an electric motor has been locked. CONSTITUTION:A herical gear 12a is rotated through a torsion bar 4c and a cylinder 12 by operating a handle shaft 4a to move a herical rack gear 13 right and left for driving a steering mechanism B-1, B-2. A gear 17 is fixed to the upper end of the cylinder 12, and meshes with a gear 22 to which the torque of an electric motor M is transmitted through a planetary gears H. Recesses 3a, 3b, etc., are externally provided on the circumferential face outside a ring gear 3 in the planetary gears H, and a lever 47 driven by an electromagnetic plunger G has been disengaged, and the plunger G is excited by turning on a transistor 23 through the output of an operation amplifier 12c during low speed operation quickly press the lever 47 against the recess 3a, etc.</p> |
