The discloure relates to a roller-skate with improved brake device. A guidance slanting upwards is disposed at a first through hole of the skate body for the mounting of a first rolling axle having a first wheel member rotatably engaged therewith. A spring mount fixed with a brake plate having brake lining underside both its ends is mounted between the first and the second wheel members. When the wheel support lurches forwards, the first wheel member will move upwards through the guidance, urging against the brake lining fixed under brake plate fixed to the spring mount to achieve the effect of braking the skate. Moreover, when pressed at one end, the brake plate, by leverage, will bend at the other end to limit the motion of the second wheel member and thus further contributes to the effectivity of the brake device.

A roller-skate with improved brake device, comprising a skate body, a skate sleeve, a wheel support, and wheel members; said skate sleeve made of sponge and fitted in the skate body to separate a user\s foot from the skate body for protection of a user\s foot; said skate body molded in the shape of a man\s foot and provided with lace holes for passage of a shoelace therethrough and ventilating through holes of various shapes to keep the interior of the shoe body ventilated; said wheel support mounted under said skate body, forming a longitudinal groove at a center of wheel support, both sides of wheel support having several through holes at equal intervals for the mounting of rolling axles, and by way of spindle bearings, fixing the wheel members inside of the longitudinal groove in a row at equal intervals; a spring mount engaged to said wheel support, a guidance slot slanting upwards on said wheel support to allow the upward movement of a first rolling axle within the guidance slot; and a brake plate engaged within the spring mount, the brake plate having a brake lining fixed in place between a first wheel member and a second wheel member; wherein when a skater lurches forward, the first rolling axle moves upwards through the guidance slot against a first end of the brake plate and the brake lining and through leverage, bends the brake plate downward so that a second end of the brake plate and brake lining engages against the second wheel member to further limit motion of the second wheel member, thereby effecting braking of both the first wheel and the second wheel member.
