Fitting structure of gutter body and gutter lid

摘要

PPROBLEM TO BE SOLVED: To provide the fitting structure of a side ditch body and a side-ditch cover in which a tilting displacement in the breadthwise direction of the side-ditch cover and the danger of a falling and a movement displacement in the longitudinal direction are prevented surely, obviating the looseness of the side-ditch cover and the position of a fitting can be set properly. PSOLUTION: In the fitting structure of the side ditch bodies 1 and the side-ditch cover 2 constituted so that both left-right ends of the cover 2 are dropped into cover receiving sections 4 extended in the longitudinal direction recessed at the upper-end internal corners of the left-right side walls 3 of the side-ditch bodies 1 and projecting curved surfaces 6 extended in the longitudinal direction formed at both-end lower corner sections of the cover 2 are received on recessed curved surfaces 5 extended in the longitudinal direction formed on the internal surfaces of cover receiving sections 4, recessed notched sections 7 opened on the curved surfaces 5 are formed in the intermediate section of the extension lengths of the curved surfaces 5, projecting sections 8 projected from the curved surfaces 6 are formed in the intermediate section of the extension lengths of the curved surfaces 6 and the projecting sections 8 are received in the notched sections 7 and the breadthwise tilting displacement and longitudinal cover 2 are controlled when the curved surfaces 6 are received on the curved surfaces 5.
