Abstract
A control wheel includes a casing, a wheel ring, a first magnetic element, a pivotal shaft and a second magnetic element. The casing includes an accommodation structure and a concave structure. The accommodation structure includes a base. The wheel ring is disposed within the accommodation structure. The wheel ring is exposed outside through the accommodation structure and the concave structure. The pivotal shaft is disposed within the wheel ring and connected with the base of the accommodation structure. The wheel ring is rotatable relative to the pivotal shaft. The first magnetic element is disposed within the wheel ring. The second magnetic element is disposed within the base of the accommodation structure. The first magnetic element of the wheel ring and the second magnetic element are magnetically attracted by each other. Consequently, a rotating speed of the wheel ring is decreased.
