  Here, FIG. 4A shows the case where the roof metal roof materials B1 and B2 are contracted, and FIG. 4C shows the expanded state.

  That is, when the horizontal metal roof materials B1 and B2 are cooled and shrunk from the time of construction, these horizontal metal roof materials B1 and B2 are all deformed to have a short length in the horizontal direction. Since the length of the fitting insertion piece 2 is longer than the contracting length, the side edge C of the roof metal metal roofing material B1, B2 is not detached from the fitting insertion piece 2, It can cope with shrinkage due to temperature changes of metal roofing materials.

  On the other hand, when the horizontal metal roof materials B1 and B2 are heated and expanded from the time of construction, the horizontal metal roof materials B1 and B2 are both deformed to have a long length in the horizontal direction.

  However, when inflating, the side edge portions C of the roof metal metal roofing materials B1 and B2 press the fitting insertion piece 2, so that the sliding piece 3 also depends on the pressing force (or expansion force). Therefore, it is possible to cope with the expansion due to the temperature change of the horizontal metal roofing materials B1 and B2 without bending the horizontal metal roofing materials B1 and B2.

  Thus, according to the connector R of the present invention, the side edge C of the side wall metal roofing material B1, B2 is not inserted into the insertion receiving piece 2 with a gap in advance, It is possible to reliably prevent rattling when the horizontal metal roof materials B1 and B2 are inserted into the insertion and reception pieces 2.

  Moreover, even if the horizontal metal roof materials B1 and B2 contract due to a temperature change, the expansion and contraction can be accommodated by the fitting insertion piece 2 formed integrally with the sliding piece 3.

  INDUSTRIAL APPLICABILITY The present invention can be effectively used as a connector for a horizontal metal roof material that can cope with expansion and contraction due to a temperature change and can prevent backlash of the horizontal metal roof material.
