PURPOSE: To provide an in-line skate excellent in ornamental property by utilizing the rotation of the wheel of an inline skate to emit a light from a light emitting element attached on the wheel.

CONSTITUTION: A disc-like permanent magnet piece 5 is fixed to the shaft 31 of an in-line skate wheel, and a set of conductive plates 61, 62 are fixed to an internal case 33 rotatably fixed to the shaft 31 through a bearing 32. The conductive plates 61, 62 are arranged opposite to the permanent magnet piece 5, respectively, and a light emitting element 7 is connected thereto through a lead wire 8. The conductive plates 61, 62 are rotated opposite to the permanent magnet piece 5 by rotating a wheel 34 fixed to the internal case 33, whereby an electromotive force is generated to light the light emitting element 7.
