A roller skate includes a wheel housing having two front and two rear panels each of which has one or more oblong holes. Two seats are secured to a shoe, and each has two plates slidably engaged onto the panels with one or more conduits or tubes which are slidably received in the oblong holes of the panels for preventing the seats from moving laterally relative to the panels. A barrel is disposed on the wheel housing, a sleeve is disposed on the rear seat and slidably engaged onto the barrel, and a spring member is stably received between the sleeve and the barrel.
