To provide a traction transmitting device in which planet shafts are supported by a carrier at one end and the movement of a bushing in the axial direction is restricted.
A traction transmitting device includes a planetary gearing mechanism 6 which has a carrier 12 to transmit the revolving motions of a plurality of planet rollers 9, and flat surface 23 are parallel formed on the peripheral surface of the planet shafts 11 in such a way as extending in the radial direction of a sun roller 7, and a columnar surface 33 capable of being in slide contact with the columnar surface 31 on the bore of a cylindrical hole 16 in the planet roller 9 is formed on the peripheral surface of each bushing 10, while a flat surface 24 capable of being in slide contact with each of the above-mentioned flat surfaces 23 is parallel formed on the bore of each groove hole 15 provided in the bushing 10 in such a way as extending in the radial direction of the sun roller 7. The planet shafts 11 are supported by the carrier 12 at one end, and a flange 19 is installed protrusively on each bushing 10 as stretching in the radial direction in the gap between the carrier 12 and planet roller 9 in such a way as slidable with the planet roller 9.
