I have a used one, but just go to CT or napa, they are not alot of money.
we’ll i dont know if this is “correct”, but i usually refer to that as the “Belt tension pulley”
just a little to help ya out in your search 
It is called the accessory belt, but just go to canadian tire and tell the guy what car you have and if it has A/C or not and he will have one for you. They are only about 30 bucks. Just make sure you get proper instructions on how to install it. You can cause yourself alot of unneeded problems if it is too tight or too loose.
