An oil supply structure may be provided in a main frame such that lubrication is smoothly performed. Additionally, at least one key may be provided protruding from the lower surface of the Oldham ring. Further, the main frame may include at least one key groove configured to receive the at least one key of the Oldham ring. Additionally, the oil supply groove may be provided separately from and in communication with the at least one key groove.
