Wire harness

A wire harness comprising:

• a flat wiring member formed in a U shape, the flat wiring member including a first portion having a straight line shape, a second portion having a straight line shape, and an intermediate portion connecting an end of the first portion and an end of the second portion to each other;
• a first case that holds the first portion;
• a second case that holds the second portion;
• a rotating structure that couples the first case and the second case to each other so as to be able to rotate relative to each other;
• and
• a space portion provided in the second case, wherein
• the first case and the second case can be engaged with each other in a state where the flat wiring member has a straight line shape,
• the flat wiring member having a straight line shape has a configuration in which the second portion extends on an extension line of the first portion in plan view,
• the flat wiring member having a straight line shape includes a first folded portion and a second folded portion,
• the intermediate portion is folded along a folding line in the first folded portion, the folding line extending in an extending direction in which the first portion extends,
• the second portion is folded, in the second folded portion, along a folding line orthogonal to the extending direction so as to allow a part of the second portion to overlap with the intermediate portion,
• the rotating structure is configured to form the second folded portion in the second portion by rotating the first case and the second case relative to each other, and
• the space portion accommodates an extra length that occurs in the second portion when the first case and the second case rotate relative to each other while forming the second folded portion.
