Sorry, but there have been no correct guesses yet. I really thought the little chain would have helped to give it away.
Ok, another hint: It is part of a wheeled vehicle. (And remember, I already said it wasn't a car part.)
Other than the comment that it spins, which it does, all guesses to this point are incorrect. I really thought this wouldn't be all that difficult.
Here's a hint: It's not a car part.
The place where I work distributed a memo indicating we can get discounted admissions to CGA and Gilroy Gardens. After having not visited CGA last season at all, I was considering a visit tomorrow or Sunday. Reading packfanlv's comments reminds me why I haven't been there in a while, and why I'll go to GG instead.
I did google for verification, but I was fairly certain I knew what it was.
Ok, what's this? This one could be too easy.
Note. This is a cutaway example. Ordinarily, you would only see the metal outer shell and not the internal components.
That's why I love this site. At least daily I see something that just totally cracks me up.
P.S. Don't feel bad, I drew a blank when I first saw the picture as well. I knew that I knew her name, but it just wouldn't come to mind.
