  • the connecting base end corresponds to the lower connecting portion 214
  • this invention is not limited to the configuration of the above-mentioned embodiment, but can be applied based on the technical ideas shown in the claims, and many embodiments can be obtained.
  • the spring plate materials 30, 30A-30K are attached to both inner surfaces of the side walls 213 facing each other in the width direction W, but the spring plate materials 30, 30A-30K may be provided on only the inner surface of one of the side walls 213.
  • the attachment state of the contact portion 34 is managed by the distance between the inner surface of the side wall 213 on which the spring plate materials 30, 30A-30K are not provided and the contact portion 34 (34a, 34b).
  • the contact portions 34 (34a, 34b) of the arm springs 31 (31a, 31b) of the spring plate materials 30, 30A to 30K provided on both inner surfaces of the side walls 213 facing each other in the width direction W are configured to face each other in the width direction W without being misaligned in the height direction H, but the contact portions 34 (34a, 34b) of the arm springs 31 (31a, 31b) may be configured to be misaligned in the height direction H.
  • the position in the height direction H of the arm spring 31 having the contact portion 34 at a predetermined position is shifted, and the positions in the height direction H of the opening side contact portion 34a of the opening side arm spring 31a and the connecting side contact portion 34b of the connecting side arm spring 31b are shifted.
  • the positions in the height direction H of the opening side arm spring 31a and the connecting side arm spring 31b are not shifted, but the positions in the height direction H of the contact portion 34 in each arm spring 31 are shifted, thereby shifting the positions in the height direction H of the opening side contact portion 34a of the opening side arm spring 31a and the connecting side contact portion 34b of the connecting side arm spring 31b.
  • the height direction H position of the opening side contact portion 34a in the opening side arm spring 31a and the height direction H position of the connecting side contact portion 34b in the connecting side arm spring 31b may be offset, and the height direction H positions of the opening side arm spring 31a and the connecting side arm spring 31b may be offset.
  • the same configuration as the spring plate material 30 described above can be achieved, and since the arm springs 31 (31a, 31b) arranged in multiple positions in the depth direction D and the contact portions 34 (34a, 34b) provided on the arm springs 31 (31a, 31b) are arranged offset from each other in the height direction H, the contact portions 34 (34a, 34b) on the arm springs 31 (31a, 31b) arranged in multiple positions in the depth direction D can be reliably arranged offset from each other in the height direction H.
  • the number of contact portions 34 in the arm spring 31 is not limited to the above number, and may be any appropriate number.
  • the spring plate material 30 is fixed to the inner surface of the side wall 213 by the welded portion 33, but the fixing method is not limited to the above-described method, and any appropriate method may be used for fixing.
  • the pillar portion 148 of the extension body 147 is formed to be thicker than the plate-shaped connection portion 111, but the thickness of the pillar portion 148 may be formed to be approximately the same as the thickness of the plate-shaped connection portion 111.
