  • Publication number: 20210291675
    Abstract: A vehicle may include an inlet provided in a vehicle body and through which energy is supplied to the vehicle; a lid covering the inlet; and a garnish constituted of resin. The garnish may cover at least a part of the vehicle body and at least a part of the lid. Arranging the lid within a range of the garnish increases a degree of freedom in layout of the inlet. The increase in the degree of freedom in the layout of the inlet means an increase in a degree of freedom in component arrangement within the vehicle body. Therefore, spatial efficiency inside the vehicle body may be improved.
