- the ring 14 is made of Teflon. (Registered trademark) or an insulating resin such as a glass epoxy resin is preferably used, but it may be made of metal. Moreover, what coated the insulating resin on the surface of the metal ring may be used. When using a metal ring, attention must be paid to the generation of arcs due to local heat during energization and shunt current shunting during an accident.

- the width dimension Wc of the outer circumference of the long axis portion of the gradient coil spring 13 is smaller than the width dimension Wa of the upper edge portion of the annular groove 12b and larger than the width dimension Wb of the bottom portion. Due to the shape and dimensional relationship between the inclined coil spring 13 and the annular groove 12b and the rigidity of the insulating ring 14, the inclined coil spring 13 is moved into the annular groove 12b depending on the assembly of the contactor 10 or the behavior due to electromagnetic force when energized. It is possible to prevent the electrical resistance from increasing or becoming unstable by twisting and contacting the bottom surface 12c of the annular groove 12b.
