Yeah looks like you are missing your torque arm.. one end bolts to that location the other to your swingarm pivot bolt. If it not there there would have to be a spacer of some sort on that swingarm bolt (hopefully someone can confirm this). Have a good look around as you may have just lost the bolt and your torque arm may be hanging and hiding behind the frame.
This is a photo of the torque arm. With the bolt missing obviously.
