  • Patent number: 9046065
    Abstract: A vehicle air intake mechanism comprises an air intake duct having an inlet end opening which opens in an axial direction, and a flow-guiding member having an outer surrounding wall that defines a flow channel in fluid communication with the inlet end opening. The outer surrounding wall has first and second end portions that extend in the axial direction. The first end portion of the outer surrounding wall surrounds an inlet end portion of the air intake duct. The first axial end of the outer surrounding wall defines a first end opening that is in fluid communication with the flow channel and that opens in the axial direction. The inlet end opening is disposed between and is spaced apart from first and second axial ends of the outer surrounding wall in the axial direction.
