You might be getting different part numbers because they don't make the 2.0 liter engine in the U.S.
My parts manual just happens to cover both the 2.0 and 2.4 but my picture of the 2.0 looks different than yours. (see picture below). If your talking about the part in my picture with the No #2 pointing to it, it's labeled as
COVER, Timing Belt ...Part Number 4777 463
