You should see G-PULLEY. The exact details may depend on the generation of 105 derailleur you've got, assuming it actually is a 105. The important thing is that it has side-to-side float, because the bushing is wider than the journal it rides in. That's simple to confirm by hand.
edit: pic of the 10-speed 105 RD pulleys. The one at the right is the upper pulley.
