PROBLEM TO BE SOLVED: To provide a joint structure of a molded member that can construct a cut-off line continued in a joint portion and further can improve workability at the time of joint.SOLUTION: A joint structure of a molded member joins an end surface of a sill 2 in a longitudinal direction to a joint surface of a jamb 3. A sheet-like sealing material 4 is interposed between the end surface of the sill 2 and the joint surface of the jamb 3. By pinching the sealing material 4 by a cut-off line forming section 240 on the end surface of the sill 2 and the joint surface of the jamb 3, a cut-off line continued in a depth direction is formed. On the sill 2, screw hole portions 28 and 29 are formed, and, on the jamb 3, protrusion portions 343 and 344 abutting against the screw hole portions 28 and 29 at positions different from the cut-off line forming portion 240 are provided. On the sealing material 4, hole portions 411 and 421 through which screws screwed into the screw hole portions 28 and 29 are inserted and insertion hole portions 412 and 422 through which the protrusion portions 343 and 344 are inserted are formed. |
