To provide a suspension line magnetic operation motion controller that transmits a required braking force in a highly effective method.
The controller includes: (a) a non-magnetic cylindrical casing 5 having an end connected to either of a trolley line T or a suspension line M and having a housing opening 5d on a housing end on the opposite side; (b) a housing 6 composed of a magnetic material and positioned inside the casing 5 so that the casing 5 meets a vertical axis of the housing 6; and (c) a piston 7 formed integrally with a rod 7b linearly moving inside the housing 6. The piston 7 is positioned inside the housing 6 so that one piston end is placed on one end of the housing 6 and the other piston end is abutted on a compression spring 8. The piston 7 is composed of a combination of a permanent magnet for generating a magnetic field, a magnetic piece 7a excited thereby and a first moving member. The magnetic field is generated so as to give a required braking force by grasping the piston and pulling at least one member 6 to the piston 7.
