PURPOSE: An upper hinge structure of a wing-body truck is provided to reduce the cost of maintenance by improving the durability and strength of a hinge, with forming a body and turning pieces integrally. CONSTITUTION: An upper hinge, installed to a ceiling frame and a cover frame of a wing-body, for rotatable coupling, comprises turning pieces(2), a body(4), a turning shaft pin(10), and a non-return pin(16). Male fitting members(8) having insertion holes(12) within are formed at an end of the turning pieces. The turning pieces are bent downward at fixed positions, and coupling portions(14) are formed at the end. Female fitting members(6), having the insertion holes within to be coupled correspondingly to the male fitting member, are formed at both ends of the upper end portion of the body. The turning shaft pin is installed, with passing through the male and female fitting members. The non-return pin is fit into the end portion of the turning shaft pin. The body and turning pieces are integrally formed and therefore, the durability and strength of the hinge is improved.
