<p><P>PROBLEM TO BE SOLVED: To provide a sheet material locking mechanism capable of reliably locking an end part of a sheet material, and reducing the man-hour during the assembling and disassembling operations. <P>SOLUTION: When assembling a corrugated fiberboard spacer 1, a second supporting surface 4b of a supporting part 4 is folded at a right angle along folding lines L9 and L10. The supporting part 4 is turned to a bottom surface part 3 side along a folding line L2, and the second supporting surface 4b is inserted from a lower end part into slits 7a and 7b. In this condition, a flap 17 of the second supporting surface 4b is folded along a folding line L11 by a finger inwardly (the direction of an arrow Y) by about 180°, and inserted in engagement holes 9a and 9b in this condition. When releasing the finger holding the flap 17 after the flap 17 is passed through the engagement holes 9a and 9b, the flap 17 is turned by the restoration force close to a substantially horizontal point, and engaged with opening edges of the engagement holes 9a and 9b. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
