摘要： The present invention relates to a movable magnet type bicycle pedal, and a shoe coupling device equipped with a means for preventing attachment of metal powder. More particularly, the present invention relates to a movable magnet type bicycle pedal and a shoe coupling device equipped with a means for preventing attachment of metal powder, wherein the shoe coupling device and the pedal are respectively provided with a magnet, and are coupled to each other by magnetic force only during pedaling, and, when the pedaling is stopped or the running of a bicycle is stopped, the coupling between the magnets is released through a magnetic separation means and at the same time metal powder attached to a shoe is caused to fall so as to prevent the metal powder from being attached to the shoe.
