    • Provided is a vehicle seat, including: a frame; a rod of which ends are held by the frame; and a pad of which back side is supported by the rod. The rod has: a the metal core; and a resin member that is injection molded under a state where the core is set in a forming mold and the core is positioned with respect to the forming mold by projections of the forming mold and covers the ends of the core. The resin member is locked on hooks that are formed on the frame, and recesses of the resin member, which are formed by the projections of the forming mold, are disposed in a position that is spaced from the hooks.
    • 提供一种车座,包括:一框架; 其端部的杆由框架保持; 并且其后侧的垫被杆支撑。 杆具有:金属芯; 以及树脂构件,其在芯设置在成形模具中并且芯通过成形模具的突起相对于成形模具定位并覆盖芯的端部的状态下注塑成型。 树脂构件被锁定在形成在框架上的钩上,并且由成形模的突起形成的树脂构件的凹部设置在与钩间隔开的位置。
