パネル。 It is a housing panel constructed by blow molding a thermoplastic plastic material into a hollow double wall structure, and includes a weld rib that compresses a part of the plasticized and molten parison during blow molding to integrally connect the double walls. A housing having a hollow double wall structure made of plastic, characterized in that the weld rib is formed linearly along the longitudinal direction of the panel, and the inner width of the weld rib is sequentially reduced to form a narrow end. panel.
