A base is mounted and rotated with the axle. A plurality of slide members are respectively and movably received in the slide paths in the base. A disk has a flange extending from a periphery of a front side of the body and a neck extends from a rear side of the body. A plurality of air holes are defined through the neck. The disk is movably mounted on the axle and rotated with the axle. The flange covers the outside of the base. The air holes are located in alignment with the apertures when in normal condition. The air holes are located off alignment with the apertures when the disk is pushed backward by the slide members affected by centrifugal force.
