PURPOSE:To accumulate a lot of power transmission rotors and to increase power transmission capacity by fixing two bearing rings of four bearing rings to a rotary shaft, using one of the other two bearing rings as an input shaft, and using the other thereof as an output shaft. CONSTITUTION:Fixed bearing rings 2, 3, an input bearing ring 4 and an output bearing ring 5 are pressed to a spherical rolling element 1. The fixed bearing rings 2, 3 respectively have projecting and recessed troidal contacting surfaces are moved in parallel to a rotary shaft by a sliding mechanism 32 and oil pressure of working fluid going in and out an oil chamber 33. The input bearing ring 4 having a recessed troidal contacting surface is connected to an input shaft 8 by a slide coupling 42, and moved in parallel to the rotary shaft by oil pressure to an oil chamber 43. The output bearing ring 5 having a projecting troidal connecting surface is also connected to an output shaft 9 by a slide coupling 52 and moved in parallel to the rotary shaft by oil pressure to an oil chamber 53.
