PURPOSE:To enable to finely adjust a coolant feed pipe by moving the pipe in a direction perpendicular to the axis by contacting the ends of a plurality of adjustment screws to be engaged radially with a cylindrical support to be fixed with the pipe. CONSTITUTION:The pipe 2 of a receiver of a line bayonet is provided perpendicularly to the axis at a cylindrical vacuum container 1 of fixed part, and an axial rotor bayonet 3 is externally protruded at one terminal board 1a. A coolant feed pipe 5 coated with a superinsulation 4 is bent in L shape and contained in the interior of the bayonet 3, the container 1 and the pipe 2. A supporting member 6 coated with superinsulation 4a is fixed into the container 1 of the terminal board 1a, adjustment screws 7 arranged radially at the end of the member 6 are engaged and the screws 7 are contacted at the ends via a ring 8 of small thermal conductivity to the pipe 5. |
