  In this case, the portion between the second movable portion 54 and the contact portion 51, the portion between the first movable portion 53 and the second movable portion 54, the first movable portion 53 and the third movable portion. 55 and the portion between the third movable portion 55 and the fixed portion 52a are bent together with the first extending portion 56b. The part which becomes 55 can be reinforced by the 1st extension part 56b, and the deformation | transformation of the part which becomes each movable part 53-55 can be prevented more effectively.

  In addition, since the first extending portion 56b is formed integrally with the carrier 56 in the punching process, the first extending portion 56b can be cut out together with the carrier 56, and the first extending portion 56b can be removed. It can be easily removed.
