PROBLEM TO BE SOLVED: To increase a rotation accuracy by preventing a radial component of force from acting on a ratchet wheel when the ratchet wheel is driven by a drive claw fitted to a swing member in a one-way intermittent feeding unit in which a one-way torque limiter is assembled in the ratchet wheel and the inner ring of the torque limiter is secured to the housing. SOLUTION: The ratchet 8 is fitted to the axial end face of the ratchet wheel 1. A drive claw 40 is fitted into a window hole in the swing member 21 facing the ratchet to be moved in the axial direction. A plate spring piece formed by cutting and erecting is formed on a plate spring material formed integrally with the surface of the swing member 21. The plate spring piece is pressed against the rear surface of the drive claw 40 to engage the drive claw 40 with the ratchet 8. COPYRIGHT: (C)2007,JPO&INPIT
