This member is manufactured by cutting an aluminum extruded material to a predetermined length in the extrusion direction.
Each support member (3) (3) has the same thickness as the width (A) of the fitting recess (22) so that it can be fitted into the fitting recess (22) of the bumper body (2) in a press-fit state. (B) is designed.

体化するものである。In this state, the ridges (21) and (21) of the bumper body (2) and the support member (3) are joined and integrated by friction stir welding. In this friction stir welding, when a probe (rod) made of a material harder than the workpiece is brought into sliding contact with the workpiece while rotating, the sliding contact portion of the workpiece with the probe is generated by frictional heat generated. A plasticized state is achieved, and the workpiece material in the plasticized state is stirred and kneaded by the probe, and by utilizing the fact that the probe is movable in the workpiece, the joining portions of the workpiece are joined to each other. It is integrated.

The probe (42) is connected to the bumper body (2) while rotating the rotor (41) and the probe (42) by using a joining device (40) provided integrally with the pin-shaped probe (42) protruding therefrom. The surface of one of the ridges (21) is brought into contact with the surface of the ridge (21) almost perpendicularly from outside. Then, the ridge (21) softens and plasticizes at the contact portion by sliding contact with the probe (42), and the probe (42) is inserted inside the ridge (21) in the thickness direction. The probe (42) is inserted by inserting the tip of the probe (42) into the support member (3) through one of the ridges (21), and the rotor (41) has a shoulder ( 41
The process is performed until a) comes into contact with the surface of the ridge (21). In addition,
The support member (3) is provided in the fitting recess (2) of the bumper body (2).

る。The probe (42) is slightly inclined backward in the traveling direction while the probe (42) is in the inserted state. ) To move relatively along the length direction. Then, frictional heat generated by the rotation of the probe (42),
Further, due to frictional heat generated due to sliding between the shoulder of the rotor (41) and the surface of the ridge (21), the ridge (21) and the support member (3) are brought close to contact with the probe (42). While being softened and plasticized and agitated, the softened portion receives the traveling pressure of the probe (42) and receives the probe (4).
After plastically flowing in such a manner as to go backward in the traveling direction of the probe (42) so as to fill the passage groove of (2), the frictional heat is rapidly lost, and the solidified material is cooled and solidified. This phenomenon is sequentially repeated with the movement of the probe (42), and by moving the probe (42) by a range substantially equal to the width of the support member (3), one end of the bumper main body (2) is finally formed. Of the ridge (21) and the support member (3) are joined and integrated.

に、合金の場合でも接合部の組成変化を生じない。According to such friction stir welding, the temperature at which the ridges (21) of the bumper body (2) and the support member (3) are plasticized is considerably lower than the melting points of these materials.
Therefore, since it belongs to the category of solid-phase bonding, the ridges (21) of the bumper main body (2) and the support members (3) throughout the bonding process.
The amount of heat input to the joint (5) is extremely small, and there is no fear of cracking or reduction in strength due to thermal distortion or thermal influence in the vicinity of the joint (5).

When the other ridge (21) and the support member (3) are friction stir welded in the same manner, one support member (3) is bonded to each of the two ridges (21). And if the other support member (3) is joined and integrated with the bumper main body (2) in the same manner as described above, as shown in FIG.
Can be obtained.

修復のための後加工も不要ないし簡単で済む。In the bumper (1) thus obtained, a decrease in strength and cracks due to the influence of heat are avoided, and the joint (5) is uniformly integrated by stirring and kneading the base material of both the bumper body and the support member. In this state, the composition and the composition do not change, so that the rigidity and strength of the joint (5) are excellent. Moreover, in this embodiment, since the support member (3) is fitted and fixed in the fitting recess (22) of the bumper body (2), mechanical strength acts in addition to the joining strength by friction stir welding. , Both are more firmly fixed. Furthermore, since the appearance of the joint is good, post-processing for surface repair as in the case of joining by ordinary welding or brazing is unnecessary or simple.

However, the probe (42) may be moved in a range narrower than the width of the support member (3), or one or a plurality of spot-like joints may be formed without moving the probe. Is also good. Furthermore, although the extruded shape is used as the bumper body and the support member, a die-cast material or a casting material may be used.
