CUT-OFF MEMBER, AND CUT-OFF STRUCTURE OF ROOF PLATE USING THE SAME

PROBLEM TO BE SOLVED: To provide a cut-off member and a cut-off structure of a roof plate using the cut-off member capable of improving sealing performance against water. SOLUTION: A cut-off member body 27 constituting the cut-off member 24 is formed in approximately T-shaped cross section with an upright part 25 of plate shape and projecting parts 26 extending orthogonally to both sides from the upper end of the upright part 25. Both ends of the projecting parts 26 are protrusively provided with pairs of cut-off protrusions 28 extending obliquely downward while opening in approximately V-shaped cross section. The proximal end side inner surfaces rather than the cut-off protrusions 28 of the projecting parts 26 are protrusively provided with auxiliary cut-off protrusions 29. The lower end of the upright part 25 is protrusively provided with a pair of guide protrusions 30 inclining so that the tips approach the projecting parts 26 side. COPYRIGHT: (C)2005,JPO&NCIPI
