<p>PROBLEM TO BE SOLVED: To provide a magnetic floating type coil for railroad, capable of preventing lowering in the fastening strength of an insulating coil and shortening time for attachment as well. SOLUTION: At molding, a bush 1A, which is produced from stainless steel in a shape of drum, is provided through the bolt fastening part of a monolayer propelling coil 6A. On an insert 3A for fixing of a coil-attaching track 15A, the hole of a large diameter is worked for forming a gap 3A with a rod part 2b of a bolt 2A on the side of the monolayer propelling coil 6A, and on the bottom side of this hole, a female hole is worked for screwing a male screw part 2a of the bolt 2A. The monolayer propeller coil 6A is expanded by temperature during summer season and electrification, the head is pressed with a flat washer 4A and a spring washer 5, and even when a bending force is applied to the rod part 2b, stress is decreased by bending the long rod part.</p> |
