REACTOR
Ring-shaped moving holes ( 2 a to 2 d ) are formed on a first supporting member ( 2 ), and holes ( 4 a to 4 d ) are formed on a second supporting member ( 4 ). A first coil ( 1 ) is rotated along the moving holes ( 2 a to 2 d ) in a state where supports ( 5 a to 5 d ) and bolts ( 6 a to 6 d ) are inserted in the moving holes ( 2 a to 2 d ) and the holes ( 4 a to 4 d ). The first coil ( 1 ) and a second coil ( 3 ) are fixed so that coil surfaces of the first coil ( 1 ) and the second coil ( 3 ) become parallel by using the supports ( 5 a to 5 d ), the bolts ( 6 a to 6 d ), and nuts ( 7 a to 7 d ).
