Abstract
An oil application roller unit including a holder having at least a shaft or bearings, an oil application roller rotatably supported by the holder, and an oil leakage prevention film closely wound around the oil application roller to pack the roller and capable of being pulled out. By pulling the oil leakage prevention film while the oil application roller remains installed in the holder, the oil application roller is rotated, and the oil leakage prevention film can be removed. Since the user is not required to make contact with the oil application roller at the time of unpacking, the hands of the user are not stained. Unpacking can thus be attained safely.
