This invention is a brake for a baby's walker. The brake's friction with the floor is increased by a slide-resisting piece attached to the braking support. It prevents the walker from sliding when the brake is against the ground. The supporting pole of the brake is extended in and out by a spring and slide mechanism. The spring and slide mechanism is located within a revolving casing. A horizontal piece on the slide is adapted to smoothly traverse the inner periphery of the casing along a helical guide. The guide forces the slide, and the brake attached to it, to move up and down as a revolving switch is turned. The guide also has a locking portion to hold the slide, and the brake, in extended position.
