Abstract:
PURPOSE:To improve the fitting to the wall face and the absorbing force, by dividing a magnetism delivery member into plural small pieces in forms to respond to the wall surface of a tube. CONSTITUTION:Inside the body 5 of an absorbing device, a permanent magnet 1 and a pole piece 3 are arranged from the upper side in this order. An electromagnetic coil 4 is formed in a ring in which the center of the pole piece 3 is inserted. A protection band 13 holds the peripheral edges of the permanent magnet 1 and the pole piece 3, and functions as a cushion between the body 5 and the both members while the both members are accomodated in the body 5.
