An in-line skating device of a roller skate has a base which is fastened to the sole of a boot of the roller skate is fastened pivotally with a wheel carrier. The wheel carrier is provided with a plurality of wheels pivoted thereto in sequence. The carrier is formed of at least two pairs of carrying plates. Two carrying plates of each pair are connected in a parallel manner and are pivoted in the longitudinal direction. The wheels are respectively pivoted between the two carrying plates. The pivoting point of two adjoining carrying plates is located on the axle of one of the wheels. When the base turns in relation to the carrier, the carrying plates of one pair displace in relation to the carrying plates of other pair, thereby enabling the wheels pivoted to the carrying plates of one of the pairs to remain in contact with the ground surface so as to enable the roller skate to be started swiftly at a fast pace.
