Vehicle imaging unit

A vehicle imaging unit comprising:

• a rearward imaging apparatus that is configured to capture an image of a side rear direction of a vehicle;
• and
• a housing that houses the rearward imaging apparatus and that is attached to a side part of a vehicle body,
• wherein
• a first imaging lens of the rearward imaging apparatus is arranged on a rear end part of the housing,
• a protrusion part that extends substantially in a vehicle front-to-rear direction is provided on a lower surface of the housing,
• the housing further houses a downward imaging apparatus that is configured to capture an image of a side lower direction of the vehicle,
• a second imaging lens of the downward imaging apparatus penetrates through a lower surface in a middle region in the vehicle front-to-rear direction of the housing and is arranged on the protrusion part,
• the protrusion part has a region that extends in a vehicle rearward direction further than the second imaging lens of the downward imaging apparatus,
• a leading edge of the protrusion part is distant from a leading edge of the housing by a same amount as a trailing edge of the protrusion part is distant from a trailing edge of the housing,
• the protrusion part includes a narrowing region of which a separation width with respect to a side surface of the vehicle body becomes narrower in the vehicle rearward direction such that, at a time of the vehicle traveling frontward, a flow rate of a first travel wind passing between the side surface of the vehicle body and the protrusion part becomes faster than a flow rate of a second travel wind passing at an outer side in a vehicle width direction of the protrusion part and the second travel wind is attracted by the first travel wind, and
• the first imaging lens of the rearward imaging apparatus is exposed toward the rearward direction of the vehicle at the outer side in the vehicle width direction of the protrusion part and at a rear side of the vehicle from the narrowing region.
