Wheel assembly for roller skate
A wheel assembly mainly comprises a pivotal seat, a locking device, a singular elastic member and a wheel. The pivotal seat includes a first end pivotally connected to a base by a mounting member for moving between an extended position and an stowed position and a second end rotatably connected to the wheel for skating. The locking device is combined with the singular elastic member as a unit, which is adapted to optionally lock the pivotal seat either in the extended position or in the extracted position by the bias force of the singular elastic member. The singular elastic member is further adapted to bias the pivotal seat for facilitating its movement between the extended position and the stowed position.
