PURPOSE:To use muscles for various types of robots by disposing many connected coil magnets in a rubber tube, and bonding them so that, when a current flows, they attract each other. CONSTITUTION:When a current flows in coil magnets 1, the magnets attract each other, and a rubber tube 2 is contracted. When the current is interrupted, the tube is returned to its original length. When a muscle having a force is provided, an iron rods are filled in the magnets. When the light weight is important, the iron rods are not filled in the magnets. In order to accelerate the movement, a vent port is opened at the coil in which the iron rod is filled to form an air exhaust passage between the magnets, thereby accelerating the movement of the magnetic force muscle.
