[jQuery] parent of "this"

[Lourenço]

Hello,

i need get the this's parent div, something like this:

<div>
  <a href="#" class="close">Close</a>
</div>

and in code..
$(".class a").click(function(){
  $(this < div).slideUp(); //here
});

that way many buttons will work with no ids and with the same code!
how can i do it?
i don't wanna use ids...
