キ装置。 The base ends of the left and right side arms of the gate-shaped brake arm are pivotally attached to the left and right truck frames that rotatably support the axles of the wheels, and the friction shoe installed between the tips of the side arms is attached to the outer periphery of the wheel. When the friction shoe is rotated in the backward rotation direction of the wheel about the pivot point at the base end of the brake arm, the brake arm pivots so that its rotation locus cuts inward from the outer periphery of the wheel. An automatic one-way brake device for a carrier car, wherein a landing point is set, and a spring is attached to the brake arm to provide elasticity so as to rotate the brake arm in a backward rotation direction of the wheel.
