In addition, the present invention minimizes the transmission of vibration and noise generated during transportation of the fuel to other devices through the combination of the structure of the inner cover member and the outer cover member and the reservoir.

The foregoing detailed description is illustrative of the present invention. In addition, the foregoing is intended to illustrate and explain the preferred embodiments of the present invention, and the present invention may be used in various other combinations, modifications, and environments. That is, it is possible to make changes or modifications within the scope of the concept of the invention disclosed in this specification, within the scope of the disclosure, and / or within the skill and knowledge of the art. The above-described embodiments illustrate the best mode for carrying out the technical idea of the present invention, and various modifications required for specific application fields and uses of the present invention are also possible. Accordingly, the detailed description of the invention is not intended to limit the invention to the disclosed embodiments. It is also to be understood that the appended claims are intended to cover such other embodiments.
