An electrode unit configuring a resistance welding device is provided with a first chassis section and a second chassis section. A plurality of stepped hole sections are formed in the first chassis section, and an electrode pin is slidably provided in each stepped hole section. On the head section of the electrode pin, a resin ball configuring a welding pressure adjusting mechanism is disposed. In the second chassis section, a screw hole is formed coaxially with each stepped hole section, and a setscrew configuring an extrusion output adjusting mechanism for adjusting an extrusion output of the electrode pin is screwed into each screw hole.

A rib of an airplane wing is prevented from deforming due to a machining load when machining a rivet hole in parts where the rib and a skin are joined. With regard to a rib that provides a connection between first and second spars of the airplane wing, the rib is formed with mounting flanges secured to a skin via a rivet, a stringer through hole for a stringer to be positioned through, and first and second cutouts facing parts where the first and second spars and the skin are connected. Since reinforcing beads are formed along the mounting flanges and reinforcing flanges are formed so as to extend in the span direction from the edges of the stringer through hole and the first and second cutouts and be connected integrally to the mounting flanges, the stiffness of the rib toward a load in the vertical direction when drilling a rivet hole can be enhanced.

A plate material is formed into a height difference adjusting member having a J-shape such that its shim portion and resilient support portion are opposed to each other. The height difference adjusting member is mounted on a spar such that the shim portion and the resilient support portion are resiliently mounted to a flange of the spar. A rear end of a leading edge skin is fixed to the flange by a fastener in a state where the shim portion of the height difference adjusting member is interposed between the leading edge skin and the flange. The shim portion adjusts a difference in height between a front end of a main body skin and the rear end of the leading edge skin. Even if a large number of height difference adjusting members are mounted on the spar, the height difference adjusting members do not fall off and are not displaced.

A drill guide jig for guiding a drill orthogonally to a curved surface of a workpiece is disclosed. The jig is provided with a guide member having a guide hole for passing a drill and a holding member for holding the guide member. The holding member has a contact part for making contact with a curved surface of the workpiece on the lower side. The contact part has two contact points for making contact with the curved surface. The two contact points are symmetrical in relation to a center axis orthogonal to a midpoint of a line segment that connects the contact points. The drill is perpendicular in relation to the curved surface of the workpiece because the guide hole is disposed along the center axis.
