PROBLEM TO BE SOLVED: To provide a joint structure of an extrusion mold material which can easily and quickly perform a strong joint of the extrusion mold material and does not cause loosening and coming off of the joint due to the vibration or shock. SOLUTION: In the joint structure of an extrusion mold material, the extrusion mold material 1 and the extrusion mold material 1 are jointed by holding a projection edge 2 provided one side extrusion mold material 1 and a holding groove 3 provided on the other side extrusion mold material 1. The projection edge 2 is continued to a side edge of the one side extrusion mold material 1 with a hook part 4 provided on a base part, a recessed stripe part 11 is formed on the inner side. The holding groove 3 is formed so as to make the form where the insertion of the projection edge 2 into the inner side is possible when a suppressing wall 8 is opened, and to make the form where the projection edge 2 and its hook part 4 are held by the suppressing wall 8 and a receiving wall 6 when caulking the suppressing wall 8 with the receiving wall 6 continued to the side edge of the other extrusion mold material 1 by the hook part 5 provided on the base part and the suppressing wall 8 corresponding to the receiving wall 6. The projection stripe part 10 engaging with the recessed stripe part 11 of the projection edge 2 is formed on the outside surface of the suppressing wall 8. COPYRIGHT: (C)2009,JPO&INPIT
