Abstract
A rotation transmission device includes coaxial input and output shafts (and), a pair of opposed bevel gears (and) rotatably mounted around the input shaft (), and an intermediate bevel gear () meshing with the opposed bevel gears (and). The output shaft () and one of the opposed bevel gears () are rotationally fixed to each other. A first one-way clutch () is provided through which the rotation of the input shaft () is transmitted to the one of the opposed bevel gears (). A second one-way clutch () is provided through which the rotation of the input shaft () in the reverse direction is transmitted to the other of the opposed bevel gears (). Thus, the output shaft () can be rotated in the normal direction irrespective of whether the input shaft () is rotated in the normal direction or in the reverse direction.
