摘要： Construction of a friction roller reducer is achieved wherein displacement of intermediate rollers due to the change in thickness in the axial direction of loading cam apparatuses can be performed smoothly, and excellent transmission efficiency can be obtained. Long guide holes that are long in the radial direction of a sun roller and ring-shaped roller are provided in guide blocks that are fastened to a support frame for supporting the end sections of rotation shafts of intermediate rollers. The outer rings of ball bearings, of which the inner rings are fitted around and fastened to the outside of the end sections of the rotation shafts, engage with the long guide holes so as to be able to displace in the radial direction of the sun roller and the ring-shaped roller.
