supercharger belt

The belt to my supercharger broke the other day. I was wondering if there is soppost to be a pulley where the idler thing is at. The part that im talking about is the wheel looking thing that is closest to the front of the car. Is there a pulley that is soppost to be connected to that. I have a 98 pontiac grand prix gtp. thanks

Hope this helps.....
