Although it passes through the side wall and passes over the luggage compartment, conventionally, the portion of the wire harness that passes over the luggage compartment is attached to the lower surface of the floor member and both ends extend through the side wall of the luggage compartment. It is housed in a gutter-shaped harness duct that penetrates and projects outward, and rainwater or water from a car wash that has been jumped up by tires adheres to the wire harness and travels along the wire harness. Even if it falls on the luggage compartment, the harness duct receives the fallen rainwater or the like and discharges it to the outside of the luggage compartment, so that rainwater or the like does not enter the luggage compartment.

[0003]

However, in the conventional structure as described above, since the harness duct is installed above the luggage compartment in the front-rear direction, the harness duct is a long member. There is a problem that the cost rises.

The present invention has been made in view of the above circumstances, and has as its object to provide an inexpensive harness duct structure that can prevent rainwater or the like transmitted through a wire harness from entering a luggage compartment.

[0005]
