PURPOSE: To make the power transmission in the title have a long life and function without trouble even under high a temperature condition by constituting a fixed ring and a sun ring with ceramics and reinforced carbon material containing heat resisting high strength fiber, in a case of constituting said both rings with the same material and rolling members with different material from said both rings.
CONSTITUTION: A rolling body 30 is constituted of a material of different property from its counterpart of combined materials for constituting a fixed ring 10 and a sum ring 20. Also, as reinforced carbon containing heat resisting high strength fiber has a deformability, assembling is easily carried out. Further, as a result of an object having deformability combined with an object relatively high hardness, a rolling element can be assembled in a state having sufficient pressed force, to the fixed ring 10 and the sun ring 20, therefore the prescribed frictional force can be attained. As reinforced carbon material containing heat resisting high strength fiber has solid lubricity together with respective superiority in heat resistance of ceramics and reinforced carbon material containing heat resisting high strength fiber, the abutting parts of the rolling element 30 to said both ring 10, 20 don't seize easily even if lubricating oil isn't used.
