Fixing wheels on my cooler box

[winnets]

So one of the wheels on my cooler box broke off so im looking to fix it. However I'm trying to find a similar nut/wheel cap tto fit on the end of the axel. What is the technical term for one of these!?

See the photo for what I mean on the working side of the box
