  In the armrest through fixing structure of the embodiment thus configured, as shown in FIG. 1 or FIG. 3, the armrest through member 25 is mounted on the passenger cabin side surface 19a of the seat back panel member 19. The room side armrest through 26 and the trunk room side armrest through 27 attached from the trunk room side 19b of the seat back panel member 19 are divided into two.

  For this reason, each of the passenger compartment side armrest through 26 and the trunk room side armrest through 27 can set the vehicle front-rear direction dimensions D1 and D2 to be shorter than those having the conventional dimension D, for example.

  Therefore, even if the draft angle α required for molding the passenger compartment side armrest through 26 and the trunk room side armrest through 27 as a resin molded product is provided, the desired dimension can be obtained without reducing the opening dimension L4. The practical opening area can be easily secured.

  Therefore, the armrest through member 25 can be configured using a resin molded product that is relatively inexpensive to manufacture.

  Next, the mounting of the armrest through member 25 on the vehicle body will be described along the mounting order. First, in this embodiment, while the trunk front side trim member 11 is attached to the trunk room side surface 19 b of the seat back panel member 19, the trunk room side armrest through 27 is connected to the peripheral edge 21 of the trunk through opening 20.
