A roller skate with a micro adjustment device includes a wheel frame, a quarter and a vamp. Two side boards of the wheel frame have a first chain and a slot. Two side boards of the vamp has a third chain and a guiding hole. The top end of the wheel frame is formed with a second chain. A quick release device is inserted with its shaft through the guiding hole of the vamp and the slot of the wheel frame, the first chain corresponding to the third chain. The shaft has a gear corresponding to the second chain. By tightening and loosening of the quick release device, the gear is adjustable with respect to the second chain, thus the third chain of the vamp is adjustable along the first chain of the wheel frame.
