Abstract

PURPOSE:To facilitate manual operation of a steering device even upon fault of motor or turning OFF of a key switch by arranging an electromagnetic clutch between the output side of a decelerator for decelerating the output of a steering assist motor and a steering device. CONSTITUTION:A rack 7 in a steering device is engaged with a pinion 4a of a pinion shaft 4 coupled through a torsion bar 2 with a steering shaft 1. A clutch plate 5 is fitted to the pinion shaft 4 and an armature 9 energized downward through a waved spring 8 is fixed to the plate 5. A gear 10 having a tooth 10a engagable with a tooth 9a provided on the armature 9 is fitted rotatably to the pinion shaft 4 so as to engage the gear 10 with a pinion 11 provided to the shaft 14 of a motor 13. A solenoid coil 12 arranged in a space 10a on the back of the gear 10, and upon excitation of the solenoid coil 12, the armature 9 is attracted and engaged with the gear 10 so as to transmit power of the motor 13 to the pinion shaft 4.
