Abstract: A roller supporting structure has a shaft having first grooves for generating a dynamic pressure, and first and second retaining plates placed opposite both ends of a roller when the roller is mounted around the shaft. The first and second retaining plates have second grooves for generating a dynamic pressure on their roller-facing end faces.
