Abstract
A long synthetic resin foam body composed of a thermoplastic resin expanded beads-molded substrate and a frame having displacement regulating sections provided at both ends in the longitudinal or lateral direction of the substrate and a connecting section that connects the displacement regulating sections to each other. The substrate has at least one joint forming portion that divides the substrate in a direction intersecting the connecting section into two or more substrate parts. The joint forming portion has a joint that connects the adjacent two substrate parts to each other and is deformable to permit a relative displacement between the adjacent two substrate parts when the substrate contracts or expands.

A long synthetic resin foam body comprising:
- a thermoplastic resin expanded beads-molded substrate that has a longitudinal direction, a lateral direction and a thickness direction, and
- a frame that has a pair of displacement regulating sections which are longitudinally or laterally spaced apart from each other and provided in said substrate at positions spaced inward from opposing longitudinal or lateral ends of said substrate and at least one connecting section which connects the paired displacement regulating sections to each other,
- said substrate having at least one joint forming portion that divides said substrate in a direction intersecting the connecting section into two or more substrate parts, said joint forming portion having at least one joint that connects adjacent two substrate parts to each other, and
- said joint being deformable to permit a relative displacement between the adjacent two substrate parts when said substrate contracts or expands.
