Vehicle underbody structure

A vehicle underbody structure comprising:

• an exhaust pipe connected to an engine housed within an engine compartment in a front of a vehicle, the exhaust pipe extending toward a rear of the vehicle;
• a unit component positioned adjacent to the exhaust pipe below a floor panel of the vehicle and rearward of the engine compartment;
• an insulator configured to protect the unit component from heat of the exhaust pipe;
• a protective plate mounted to a front of the unit component and configured to protect the unit component from road surface interference;
• an undercover configured to cover an underside of the vehicle;
• and
• an insulator cover member positioned forward of the unit component and configured to cover the insulator by covering a lower portion of the exhaust pipe, wherein
• the undercover includes a first opening exposing a portion of the insulator cover member,
• an outer peripheral surface of the exhaust pipe is covered by the insulator cover member and the insulator at the front of the unit component,
• the insulator cover member includes
• a shielding wall portion configured to shield a space between the exhaust pipe and the protective plate, the shielding wall portion extending downward along the exhaust pipe from the engine compartment toward the undercover, and
• a second opening that opens toward the underside of the vehicle, the second opening communicating with an underside space of the vehicle via the first opening.
