  • heat transfer to the stopper element 18 can be further suppressed.
  • first portion 73A and the second portion 73B are preferably arranged coaxially. If the central axis of the second portion 73B is positioned outside the cross section of the first portion 73A, the second portion 73B may come into contact with the inner surface of the through hole h1 formed in the stopper element 18 by the first portion 73A. .
  • first portion 73A and the second portion 73B are arranged coaxially, by adjusting the shape of the second portion 73B, the entire second portion 73B can be adjusted to the outer peripheral surface of the first portion 73A when viewed from the insertion direction. can be located inside the As a result, a gap S1 can be provided between the second portion 73B and the stopper element 18 over the entire circumference, so that heat transfer to the stopper element 18 can be further suppressed.
