PROBLEM TO BE SOLVED: To provide a friction roller type transmission which inhibits increase of an outer diameter dimension and contributes to weight reduction.SOLUTION: A friction roller type transmission includes: an input shaft 10; a sun roller 20 comprising a pair of sun roller elements 20A, 20B; an annular roller 40; an intermediate roller 30; an output shaft 50 which is connected with the annular roller through a connection bracket 70 so as to transmit torque thereto; and a loading cam mechanism 60 which changes rolling contact surface pressures between the respective rollers. An engagement protruding part 110, which is a torque transmission part TB of the annular roller and the connection bracket, and an engagement recessed part 130, which engages with the engagement protruding part 110, are provided at a side surface part of the annular roller 40. |
