INTAKE DUCT

An intake duct includes a duct body. The duct body includes an upstream opening and a downstream opening. The duct body includes a twisted and bent portion. The twisted and bent portion includes a first side section and a second side section. The upstream opening and the downstream opening respectively include first sections, which are on a first side in the height direction. The upstream opening and the downstream opening respectively include second sections, which are on a second side in the height direction. The twisted and bent portion is twisted and bent such that the first side section connects the first section of the upstream opening and the second section of the downstream opening to each other, and the second side section connects the second section of the upstream opening and the first section of the downstream opening to each other.
