PROBLEM TO BE SOLVED: To provide a T-shape joint into which a sheet fastening material is inserted to connect in a T-shape crossing form. SOLUTION: This T-shape joint is formed in an almost T-shape when being viewed in a plane direction, by a T-shape leg connecting part 1 into which a sheet fastening material k can be inserted to be connected in the same direction as a T-shape leg, and a T-shape head connecting part 2 into which the sheet fastening material k can be inserted to be connected in a penetration condition in the same direction as a T shape head. The T-shape leg connecting part 1 has holding sides 3 which are formed on both the edge parts and hold the outer surfaces of both the side wall lower parts of the sheet fastening material k. The T-shape head connecting part 2 is formed with holding sides which hold the outer surface of both the side wall lower parts of the sheet fastening material k, each on an upper side crossing the T-shape leg connecting part 1 at right angles, and lower sides divided into right and left. The upper side is formed with a holding side 5 which extends over the total length, and the two lower sides divided into right and left are each formed with holding sides 6 and 6. The upper half of the holding sides 6 and 6 of the lower sides is formed in an outward curved invitation part 9. COPYRIGHT: (C)2009,JPO&INPIT
