おりとすることが望ましい。FIG. 2 is a sectional view showing a pedestal and a sliding member, which are constituent members of the present invention, and FIG. 3 is a sectional view showing a state where the sliding member is being joined to the pedestal part. As shown in FIG. 2', the sliding member 1 is a flat plate made of a wear-resistant metal such as stainless steel, which has a plurality of grooves formed inside both ends, and is processed into a zero shape by roll forming. - On the other hand, it is made of a highly conductive metal such as copper or aluminum as a body through which a large current flows, and has a pair of protrusions 4.4 bent outward on both sides of the head 31, and a pair of protrusions 4.4 on the lower side thereof. Recess 5
, 5 is manufactured by extrusion molding or the like. In this case, the width dimension W1 between the left and right inner surfaces of the sliding member 1 and the mount 3
It is desirable that the relationship between the width dimension W2 between the left and right outer surfaces of the head 31 is as follows.

Apply the protruding roll 6.6 to the pair of recesses 5, 5 provided on the lower side of the head 31 of the W4 roll 7 and the roll 6.
6 to form the concave portion 5.5 into a V-shape, thereby expanding it to a width W3 larger than the width W1 between the left and right inner surfaces of the sliding member 1. At this time, since the upper surface of the sliding member 1 is restrained by the grooved roll 7, the compressed metal parts around the recesses 5, 5 fill the inner surface of the sliding member 1 and the groove 2 due to the deformed flow E.

るものである。Next, the protrusions 3 are installed on both sides of the head 31 of the pedestal 3.
The protrusions 4, 4 are brought into close contact with the outer end of the sliding member 1 by compressing the portions 4, 4 so that the opening outer width dimension W4 of the sliding member 1 does not become smaller than the non-opening outer width dimension WO. Expanding the opening width of the sliding member 10 within the range of elastic deformation in this way improves the adhesion with the pedestal portion 31.
