Abstract
A roller skate includes a fixing seat, a plurality of wheels, and a safety device mounted on the wheel. The safety device includes a safety member mounted on the fixing seat and urged on the wheel, so as to adjust a rotation speed of the wheel. Thus, the roller skate can be fixed on the ground without rotation by the safety device, so that the learner can stand on the roller skate without movement so as to practice his/her balance. In addition, the safety member is slightly loosened from the wheels, so that the wheels are rotated at a lower speed, thereby facilitating the learner practicing the skating skill.
