PURPOSE:To improve rotation precision of a driven shaft, by a method wherein a one-way clutch is mounted in the one coupling on the driving mechanism side or the driven unit side, and by mounting a driven unit to a vehicle body, a rotation force can be transmitted through the clutch. CONSTITUTION:A coupling 25 is secured on the output side of a driving shaft 16, and a coupling 26 is secured to the coupling 25 by means of a screw. A one-way clutch 27 is securely pressure-fitted in the coupling 26, and the tip part of a driven shaft 19 is inserted in the inner wheel of the one-way clutch 27 in a state in that a driven unit is mounted in a device body. This constitution enables the rotation force of the driving shaft 16 to be transmitted to the driven shaft 19 through the one-way clutch 27, rotation precision of the driving shaft 16 to be transmitted to the driven shaft 19 as it is, and improvement of rotation precision of the driven shaft 19.
