Abstract: A thermal insulating structure of a fuel tank for a motor vehicle, which is readily produced and attached without using any protector for a thermal insulating member. In the thermal insulating structure of the fuel tank mounted under a floor panel of the motor vehicle, at least an entire side surface and an entire bottom surface of the fuel tank are covered with a thermal insulating member that is formed previously. The thermal insulating member includes a foamed layer on an interior side thereof, and an outer layer made of a solid material. The thermal insulating member is attached to the floor panel along with the fuel tank by means of a tank attaching member.

Abstract: A vehicle body structure having a lock device for use of a package tray installed in a vehicle. A package tray is provided within a luggage compartment to conceal a luggage from the outside. In a two box car, a luggage compartment is communicated with a passenger compartment. Hence, even if a hatch back door is closed and locked, a luggage put in a luggage compartment might be stolen if a front or rear door is opened. The lock device makes the package tray locked, thereby disconnecting the communication between the passenger compartment and the luggage compartment.
