Abstract

PURPOSE:To surely prevent a vehicle from reversing, when it is started on a sloping road, by locking a parking gear, arranged in a transfer axle case, when a side brake is applied, and releasing the parking gear from its lock when an accelerator pedal obtains its step-in distance to a predetermined value or more. CONSTITUTION:A parking gear 7 is fixed to an output shaft rotatably supported in a transfer axle case, and by engaging a stopper protrusive part 15A of a lock means 15 with a toothed part 7A of the gear 7, the output shaft 6 can be inhibited from its turning. Forming an attracting surface 15B in an end part in an opposite side to the stopper protrusive part 15A of the lock means 15, it is swiveled against a spring 15C by excitation of an electromagnet 16, engaging the stopper protrusive part 15A with the toothed part 7A. And energizing the electromagnet 16 by a control means C, when a hand brake is detected in its action by a hand brake detecting means A, the electromagnet 16 is controlled so as to be deenergized when a pedal step in distance of predetermined value or more is detected by an accelerator pedal step-in distance detecting means B.
