とを特徴とする遊星ローラ式動力伝達装置。[Scope of Claim for Utility Model Registration] A cylindrical unit case having a through hole, and a unit case that is inserted into the through hole of the unit case from both left and right open ends in abutting state, and the outer ends of each are supported via rolling bearings. The high-speed shaft and low-speed shaft are press-fitted so as to be able to frictionally roll between the inner peripheral surface of the area between the rolling bearings on both sides of the unit case and the inner end of the high-speed shaft, and are rotatable on the inner end of the low-speed shaft. In a planetary roller type power transmission device having a configuration including a plurality of planetary rollers freely held on a circumference, an end surface of the unit case is caulked to an outer end surface of the rolling bearings on both sides, so that the rolling bearings is positioned and held in the unit case, and a chamfered portion for absorbing plastic strain caused by the caulking is provided at an end of an outer peripheral surface of the unit case.
