The method fixing the drive shaft to the proximal end of the hub or to the opening of the interlocking member by frictional force, and applying a coating solution containing the drug to the outer surface of the balloon from a dispensing tube while gradually moving the dispensing tube in the axial direction and simultaneously rotating the drive shaft to rotate the balloon catheter around the axis of the balloon catheter.
