  • Mechanism for converting rotational motion into linear motion
    Patent number: 8162794
    Abstract: A rotation/linear motion conversion mechanism provided with an annular shaft, a sun shaft arranged inside the annular shaft, planetary shafts arranged around the sun shaft, and a first gear mechanism and a second gear mechanism, which transmit force between the annular shaft and the planetary shafts. Each planetary shaft includes a first planetary gear, which configures part of the first gear mechanism, and a second gear, which configures part of the second gear mechanism. The planetary shaft is configured to permit relative rotation between the first planetary gear and the second planetary gear.
