A three-wheel roller skate comprises a sole plate and a connecting member mounted in the sole plate. An inner rod is extended through the connecting member. A wheel rod is integrally formed with an end of the inner end and provides an axle for mounting a rear wheel. The connecting member comprises a longitudinal through-slot and a groove in an end face thereof. A pin extends through a transverse hole in an end of the inner rod that extends through a longitudinal hole of the connecting member. The pin is turned through an angle so as to place the pin into the groove of the connecting member. A nut engaged on a threaded section of the inner rod is then turned to move the rear wheel away from the sole plate to a locked state.
