Electrical – How is ground wire handled on 240V outlet

240velectricalwiring

I'm in the process of moving 240V outlet. The outlet has three wires connected.

See the image:
outlet with 3 wires and ground missing

In the junction box I can see the ground coming out of the outlet.

So where is the ground wire inside the outlet? I'd like to know how this is handled.
Update: for some reason I didn't notice ground attached to the neutral. But it is there

Then I noticed a orange label and found the instruction:

So I wired the stove cord according to the code:

Measured all the connections with the voltmeter and all is now set up correctly. Thanks to everyone!

That outlet looks like a NEMA 10-20 or 10-50 and is an ungrounded outlet. There are two 120V hot lines and one neutral.

This is an old outlet type and is no longer permitted in new installations.
