PROBLEM TO BE SOLVED: To provide a water droplet removing mechanism that can remove a water droplet and mud obstructing imaging from a lens surface of a rearview imaging device without using electricity, and to provide an on-board camera including the same.SOLUTION: The water droplet removing mechanism includes a compressed air injection part 20 for injecting compressed air to the lens surface 13 of the rearview imaging device 10 for imaging a vehicle rear side to clean the lens surface. The compressed air injection part 20 includes: a heavy bob 22 movable during travelling of a vehicle; a volume changing part 23 where a volume changes in accordance with the movement of the heavy bob; and an injection nozzle 24 communicated to the volume changing part to inject compressed air to the lens surface of the rearview imaging device.SELECTED DRAWING: Figure 1
