Claims

[Scope of utility model registration request]

A bending part main body consisting of inner and outer walls and a bottom wall and having a U-shaped cross section with an open top surface and having a bent part in the middle, and a flat plate-shaped bending part lid that is fitted into the upper opening of the bending part main body and has a bending part in the middle. a pair of first longitudinal protrusions are formed in the height direction with a small gap between the outer wall bending portion and the inner wall bending portion of the bending portion main body; second longitudinal protrusions are formed in the height direction opposite to the inner surfaces of both ends of the inner and outer walls of A third longitudinal protrusion is formed in parallel, and the duct body is internally fitted in such a way that it is slightly inside from both end faces of the bending part main body relative to the thickness of the inner and outer walls and the bottom wall of both end faces. A fitting part having a U-shaped cross section with an open upper surface is formed protrudingly, and is fitted into the gap between the first longitudinal protrusions of the bending part main body facing the back surface in the width direction of the bending part of the bending part cover plate. a second protrusion fitted between the second and third longitudinal protrusions of the bending part main body facing the back surface near both ends of the bending part cover plate; and extending both ends of the bent part cover plate to the outer end positions of the fitting parts at both ends of the bent part main body to form extension parts, and facing each other in the longitudinal direction of the back surface of the extension parts. A bent portion of a wiring duct, characterized in that horizontal protrusions are formed into which the upper end portion of the duct body is internally fitted.
