[Problems to be solved by the invention]
However, in the above, when one or both of the upper panel (41) and the lower panel (42) are bent in the pushing direction, the tip of the protruding wall (48) of the lower panel (42) and the upper panel (41) A conspicuous gap (S) tends to occur between the substantially inverted V-shaped groove (52). This gap (S) is not preferable because it deteriorates the appearance of the joined panels and foreign matter enters the gap (S).
[0004]
Therefore, in order to eliminate the gap (S), even when a short coupling pin (43) may be press-fitted only at both ends of the pin hole (47) in terms of the coupling strength between the panels (41) and (42). is forced to be pressed pin hole (47) of the coupling pin of the long in the same length as the length (43) over the entire length of the pin hole (47), press-fitting of the coupling pin of such a long (43) is very Therefore, there is a problem that it takes a lot of time and labor to join the panels (41) and (42).
[0005]
An object of the present invention, even if there is the extrusion direction of the bend in the extruded profile, without press fitting the coupling pin of the long entire length of the pin hole, between the bending of the extruded profile are easily corrected extruded profile in conspicuous binding extruded profile which gap is to prevent the resulting, to provide a method for manufacturing a coupling for the extruded profile and the binding extruded material.
