Movable magnet bicycle pedal, and shoe coupling device equipped with means for preventing attachment of metal powder

A shoe coupling device provided with a mobile magnet bicycle pedal and a metal powder attachment preventing means, comprising:

• a shoe coupling device which is coupled to the sole of a shoe and includes a magnetic separation means configured to weaken or reduce magnetic force and separate metal debris or powder;
• a plurality of magnet guide members, each of which includes a first magnetic body built therein in such a way that coupling or decoupling is implemented by repulsive force or attraction between the magnetic separation means and the magnetic body, and which is connected to one another to move upward and downward;
• an operation support housing to which opposite ends of the plurality of magnet guide members are coupled to enable vertical movement, and to which a pedal shaft is further coupled;
• and
• a pedal frame to which the operation support housing is coupled, wherein each magnet guide member has vertical movement when pedaling while improving contact force to the sole of the shoe.
