Abstract

The present invention relates to a detachable type roller skate capable of preventing a backward motion which includes a front plate unit in which a slanted female threaded portion is formed in a plate-shaped upper center portion, a rear member in which a female threaded portion corresponding to the male threaded portion is formed in one side, a left and right fixing plate member in which a male threaded portion corresponding to the female threaded portion of the front member is formed in one side, a front roller portion in which a front roller is installed in both sides of a rotary shaft having a plurality of male threaded portions each having a certain slanted angle, a rear roller portion in which a rear roller is installed at both sides of the rotary shaft having a plurality of male threaded portions each slanted at a certain angle, a brake roller formed in the same circular shape as the front and rear rollers, in which a rubber braking portion is attached on an outer circumferential surface, an elongated hole is formed in the center portion of the side plate at a certain slanted angle, a shaft is inserted into the elongated hole, and the brake roller is installed just behind the rear roller for thereby providing a braking force; and a binding band formed of binding clips and having an adjustable length.
