じさせるおそれがあり、強度的に問題がある。However, in the structure in which the cross fitting portions are joined by friction stir welding as described above, the joining tool cannot be operated on the corner portion, which is unique to the friction stir welding method. For this reason, as described above, the joining is performed only to the part (53) in the butted state in the boundary between the meats of the two frame members (51) and (52). The butted portion (53) is a place where a large stress is applied when a force such as torsion or pulling is applied. Therefore, there is a possibility that the friction stir welding portion may be broken, and there is a problem in strength.

There is also a problem that high precision is required for the processing of 2a).

The problem is solved by the fitting connection structure.

も可能となる。That is, since the core is arranged in such a manner as to fill the gap between the two members in the fitting portion, it is possible to perform a strong joining utilizing the core. For example, in the case of the friction stir welding method, the first member and the core, and the second member and the core can be friction stir welded in the form of a lap joint, respectively. It becomes difficult to join both members firmly and firmly. In addition, since it is not necessary to perform joining at the butted portion, high precision is not required for processing the notched portion. Further, in the case of mechanical joining using bolts, rivets, or the like, the core supports the force in the collapsing direction due to the tightening, and it is possible to join firmly without causing the members to collapse. Furthermore, the use of the core increases the bonding area, and enables bonding with an adhesive.

Abut against the outer surface of Thereafter, the rotor (3) is moved while maintaining the rotating state. In the portion where the rotor (3) passes, the surrounding material is softened and stirred by the frictional heat generated by the rotation of the rotor (3), and the scattering is restricted by the shoulder (6) of the rotor body (9). While plastically flowing so as to fill the passage groove of the probe (4), heat is rapidly lost and solidified by cooling. Thus,
The softening, close contact deformation, agitation, and cooling and solidification of the meat of the wall (2b) and the core (8) of the second frame (2) are sequentially repeated with the movement of the rotor (3). The wall (2b) of the frame material (2) and the core (8) are joined to each other (7)

I will do it. As described above, the cross portion between the first frame member (1) and the second frame member (2) is joined as shown in FIG. Thus, this friction stir welding method is to join in a softened state without melting the material,
There is no problem in quality due to the influence of heat or the like as in the case of welding, and high quality joints (7) (7) are formed.

During the rotational insertion of the probe (4) into the meat of the member, the probe (4) is moved to the workpiece. Bias in the direction opposite to the insertion direction,
The meat softened by the reaction force of the urging force is effectively stirred. Instead of the screw (5), various grooves and irregularities may be formed on the outer peripheral surface of the probe (4). By using the probe (4) having such a configuration, the joining in the lap joint type as described above can be further firmly performed.

Since the core (8) is arranged in the mode (2) of filling the gap (10) in the fitting portion of the cross portion, as described above, the first frame is formed by using the core (8). The material (1) and the core (8), and the second frame material (2) and the core (8) can be friction stir welded in the form of a lap joint, respectively, and a large joint area can be ensured. )
(2) can be firmly joined. In addition, this lap joint type joining can eliminate the joining at the butted portion of the frame members (1) and (2), and a slight dimensional error occurs in the processing of the notched portions (1a) and (2a). Is acceptable. Further, since the frame members having a rectangular cross section can be joined by performing friction stir welding at the center portions of the walls (1b) and (2b) of the frame members (1) and (2), the frame members (1) and (2) can be used. Even if a force such as torsion or tension acts on 2), it is possible to avoid that a large stress acts on these joints (7) and (7), and it is possible to reduce the possibility of occurrence of troubles such as breakage. Note that the friction stir welding may be performed without moving the welding tool (3) to form a point-like welded portion.
