  • the support base portion 62 can slide in the forward direction D11 or the backward direction D12 relative to the machine base 10, so the nozzle touch force P2 is generated mainly in the connecting pin 84 of the connecting member 34.

  • a position at which one or a pair of the second linear guide members are provided may be lower than a position at which a pair of the first linear guide members are provided.
  • Appendix 3 In the injection molding machine described in Appendix 1 or 2, when a nozzle (46) of the injection machine is in contact with the mold pieces, a portion of the first support member and a portion of the second support member may overlap in a plan view.
  • a portion of the structure may be positioned between a portion of the first support member and a portion of the second support member when a nozzle of the injection machine is in contact with the mold pieces.
  • the pair of first linear guide members may be arranged symmetrically with respect to an axis of a nozzle of the injector, and the pair of second linear guide members may be arranged symmetrically with respect to an axis of the nozzle of the injector.
  • the second support member may have a plurality of guide blocks (114) each moving on the second linear guide member, and the structure may be supported by the plurality of guide blocks.
  • Appendix 8 An injection molding machine according to any one of Appendices 1 to 7, comprising a machine base (10) having a first mounting surface (10F2) on which the first linear guide member is mounted and a second mounting surface (10F1) on which the second linear guide member is mounted, and the second mounting surface may be lower than the first mounting surface.
  • the structure may be a connecting member (34) that connects the fixed platen and the injection machine.
