LoopUp (rc2 or earlier) dedicated accelerator
It is an asymmetric accelerator only for LoopUp.
It is not a mistake to say that it is the most important part in LoopUp.
We are strengthening, but if you tighten it too strongly, the screw part will lick
If you feel that the fixing force during use has decreased, replace the shaft.
※ There is no need to replace first if you get used to it, but it is easy to damage the inside of the beginning
Please use it carefully in the state of the axis.
