PROBLEM TO BE SOLVED: To reduce the number of knockdowns to reduce manufacturing costs and to improve appearance by simplifying a connecting and oscillating mechanism for panels such as ceiling panels, eliminating the need for conventional steel hinges, reducing panel assembling man-hours, ensuring the accuracy of connecting the panels, maintaining the airtightness of the connections of the panels, and omitting conventional mounting of gaskets. SOLUTION: The second hinge component part 22 of a second panel 2 is fitted into the recessed part 19 of the first hinge component part 12 of a first panel 1 and the projecting surface part 24 of the right overhanging part 23 of the second hinge component part 22 is made to abut along the guide surface 14a of a left projecting part 14, the guide surface 14a having an arcuate cross section. The end face 27 of the end of a lower projecting part 26 having an arcuate cross section is locked to the upper projecting part 16 of the first hinge component part 12. When the second panel 2 oscillates downward almost 120 deg., the projecting surface part 24 of the right overhanging part 23 of the second hinge component part 22 moves along the guide surface 14a of the left projecting part 14 of the first hinge component part 12 and the second panel 2 oscillates about the end of the lower projecting part 26 of the second hinge component part 22. |
