Abstract:
A one-way rotational transfer mechanism comprising:a rotary input shaft having an orthogonal surface lying in a plane orthogonal to an axis of said rotary input shaft; a hollow-cylindrical rotary output shaft positioned around said rotary input shaft to be freely rotatable relative to said rotary input shaft about said axis thereof, said hollow-cylindrical rotary output shaft having a cylindrical inner peripheral surface about said axis of said rotary input shaft; a circumferentially-uneven-width-space forming portion formed on said rotary input shaft to be adjacent to said orthogonal surface to form at least one accommodation space between said rotary input shaft and said cylindrical inner peripheral surface; at least one rotatable member installed in said accommodation space; and a biasing device for making said orthogonal surface and said rotatable member come into pressing contact with each other, wherein said circumferentially-uneven-width-space forming portion is shaped so that a rotation of said rotary input shaft is transferred to said hollow-cylindrical rotary output shaft via said rotatable member to which said rotation is given from said orthogonal surface when said rotary input shaft is driven to rotate.
