In a wing of an airplane, a front spar having a C-shape in section includes a web, flanges, and a reinforcing partition wall. An intermediate spar having an I-shape in section includes a web, flanges, and a reinforcing partition wall. Ribs can be positioned in a span direction by coupling front and rear portions of the ribs to the reinforcing partition wall of the front spar and the reinforcing partition wall of the intermediate spar, without the provision of an assembling jig having a positioning function and without the use of a special positioning member. In addition, the ribs can be positioned in a cord direction by bringing rear ends of the ribs into abutment against a front surface of the web of the intermediate spar. Thus, it is possible to assemble the wing of the airplane using an inexpensive assembling jig having no rib-positioning function.
