PURPOSE: To allow injected hardening foam to completely adhere to the wall of a housing formed by external members by injecting the hardening foam components between the first and second members of a ski, and performing expansion and hardening processes. CONSTITUTION: During injection in an afterprocess, solid films 9, 90 having affinity, which are made from a polymer with a good adhesive property to hardening foam 15, are prepared. A ski comprises a main sub-assembly, i.e., an upper sub-assembly or a first member 1 and a lower sub-assembly, or a second member 2. The members are coupled together during an assembly operation by injection the hardening foam 15 into a closed space formed by the sub-assemblies 1, 2. |
