ABSTRACT:
A ventilating skate including a skate body formed with several circular or polygonal through holes in which ventilating disks are disposed. One side of the ventilating disk is formed with a ventilating groove. A pivot plate formed with multiple through holes is rotatably connected with the ventilating disk to locate the same in the through hole of the skate body. The ventilating disk can be rotated to adjust the orientation of the ventilating groove and thus adjust the amount of incoming air. A whistling film is disposed in the ventilating groove, whereby when skating with the air passing through the ventilating groove, the whistling film is vibrated to emit a sound.
