In a classic sense, the B737, doesn't have a real "Elephant Ear" like the DC-9 does, I believe they are mistaken. The elephant ear is more or less a fairing connected to the inner most portion of the inboard flap. This fairing (elephant ear), when flaps are retracted, fairs with the aircraft lower wing to body fairing, creating an aerodynamic fit with the flap and aircraft fairing.
This parts looks like a portion of the lower wing to body fairing. Elephant ears are classic back bruisers when flaps are down. Often a mechanic will hit his/her back on it doing inspections in that area looking for flap damage from the main tires.
If you look very close at this DC-9, at the left inboard flap, you will notice what is called an elephant ear, hanging down slightly. You have to actually rig this in C Check and a gap check is required to the aircraft body.
Now look at the B737 here same place no fairing on the flap. If I am not mistaken this is the panel that gets crunched sometimes when flaps are extended/retracted and it catches the flap in transit. You can see it on the aircraft side in this picture clearly.
