  • the plate 40' is provided with a plurality of small slits in addition to the slit 42 connecting the insertion hole 41 and one side (downward side) of the plate 40'.
  • the small slit extends from the insertion hole 41 to the left, right, or up, but is not connected to any side of the plate 40'.
  • the small slit is provided to further reduce the press-fitting stress when the second connection component 32 is press-fitted into the insertion hole 41.
