ABSTRACT:
A ratchet wheel, connected to a motor through a worm gear and a worm wheel, is supported on a pedal shaft which pivotally supports a brake pedal. The ratchet wheel engages a ratchet member mounted on the brake pedal. When the brake pedal is depressed, the ratchet member rotates on the pedal shaft so that the brake pedal is turned with the ratchet wheel remaining stationary. When the motor is driven, the ratchet member is brought into engagement, so that the brake pedal is turned along with the ratchet wheel. When the ratchet member is operated by a release arm, the brake pedal is released from the ratchet wheel and returned to an original position.
