PURPOSE:To obtain an efficiently moldable loop-shaped armrest having appearance and touch same as those of a thick-walled molded product and having no sink or swirl mark. CONSTITUTION:A hollow part 5 is formed to a loop part 3 constituted of an armrest part 1 and a support part 2. By the presence of the hollow part 3, appearance is same to that of a thick-walled molded product but a substantial wall thickness can be reduced and touch and a surface state are improved and the cooling time at the time of molding is reduced. |
