To favorably feed lubricating oil in sliding faces of a support pin, an inner roller, and planetary rollers.

In a planetary roller type friction gearing T/D provided with a sun roller 23, planetary rollers 24, a ring roller 25, and a carrier 26, rotatably fitting each planetary roller to the outer circumference of the support pin 27 cantilevered to the carrier, interposing an inner roller 28 promoting the rotation of the planetary roller between the internal circumference of each planetary roller and the outer circumference of the support pin, and providing a presser ring 29 regulating the axial movement of the inner roller and the planetary roller in the axial other side of the roller, the inside diameter R2 of the presser ring 29 is set to such a dimension as, at least, exposing parts of the internal/ outer circumferences of the inner roller 28.
