Rotation transmission device

A rotation transmission device comprising:

• an input shaft having first and second opposite end portions;
• an output shaft arranged at the first end portion of the input shaft so as to be coaxial with the input shaft;
• opposed first and second bevel gears, said first bevel gear being rotationally fixed to the output shaft;
• an intermediate bevel gear meshing with the first and second bevel gears;
• a first one-way clutch operably coupled between the input shaft and the output shaft at the first end portion of the input shaft and configured such that rotation of the input shaft in the normal direction is transmitted to the output shaft or the first bevel gear through the first one-way clutch;
• and
• a second one-way clutch operably coupled between the input shaft and the second bevel gear at the second end portion of the input shaft and configured such that rotation of the input shaft in the reverse direction is transmitted to the second bevel gear through the second one-way clutch;
• wherein the first one-way clutch is operably coupled with the input shaft at a position such that the first end portion of the input shaft extends axially beyond the first one-way clutch in a direction away from the second end portion of the input shaft;
• and
• wherein the input shaft, the output shaft, the first and second bevel gears, the intermediate bevel gear, and the first and second one-way clutches are configured such that rotations of the input shaft in both a normal direction and a reverse direction are converted to rotation of the output shaft in one direction.
