- the rear surface 10a faces the core 3, and the rear surface 10a of the core 3 is inserted so that the projections 20, 30 enter the large holes 12, 12. Lay on the surface.
- the integral molding member 10 is slid in the direction of arrow A until the mark 73 matches the concave portion 81A, and the protrusions 20, 30 are guided to the narrow portion 13 and the wide portion 14, respectively.
- the root portions 21 and 31 are arranged in the narrow portions 13 and 13
- the head portions 22 and 32 are arranged in the wide portions 14 and 14, and the end of the integral molding member 10 is To fit.
- the width of the heads 22, 32 (the width in the width direction of the narrow portion 13) is larger than the width of the narrow portion 13, and the depth of the narrow portion 13 is equal to the roots 21, 31, respectively. Identical or only slightly larger.
- the pocket portion 40 is slightly larger than the end of the integral molding member 10. Thereby, the integrally molded member 10 is firmly attached to the core 3 via the pocket portion 40 and the projections 20 and 30.
- the sheet pad is subjected to foam molding in the same manner as described above, and after the foam is cured, the mold is opened and the mold is released. As a result, a sheet pad 90 in which the sheet pad main body 91 made of a foam and the integral molding member 10 are integrated is molded.
- the seat pad body 91 is provided with marks 81 and 82 formed of convex portions formed by the concave portions 81A and 82A.
- the mark 82 may be arranged on the side opposite to the position shown in FIG.
- the marks 81 and 82 may be provided on three or four sides of the integrally molded member 10, respectively.
- the marks 81 and 82 may be recesses recessed from the surface of the seat pad body 91.
- the marks 71 and 72 are narrow lines and the widths of the marks 81 and 82 are large, but conversely, the marks 81 and 82 may be narrow and the marks 71 and 72 may be wide. .
- the fifth aspect it is possible to accurately check whether or not the position of the body molding member of the resin foam having the integrally molded member is within the allowable range.
