  • the yoke 65 of the electromagnet block 3 is press-fitted into the second space 8 of the base 1, but parts other than the yoke 65 may be press-fitted.
  • a part of the spool 60 of the electromagnet block 3 (such as a press-fitting part formed by extending a part of the flange part 59) may be press-fitted.
  • the base 1 is formed with a plurality of protrusions having an arcuate cross section extending from one end side to the other end side.
  • the base 1 is not limited to the protrusions, and may be composed of a plurality of protrusions. It is. In short, any structure that can obtain a reference position for supporting the contact mechanism portion 2 and the electromagnet block 3 may be used.
