That may not be the stock idler pulley, I have never heard of Toyota dealer supplying this kit before, perhaps they made a few revisions to try to help solve any belt issues. Especially since they said they had issues before, the normal stock idler is 70mm daim 27mm wide, the dorman i listed before is 76mm diam and 33mm wide. but your measurement in the picture shows it is 27mm wide? as you are starting on the 5mm?
That cover looks like a pulley bearing cover used to keep sand/dirt out of the bearings in the pulley, it does not go to the normal sprintex kit, although again may be supplied by Toyota with that new pulley to try to solve some sort of issue. It would typically go just as the picture illustrates in between bolt and pulley.
