A planetary friction gear continuously variable transmission comprising: an input shaft which is rotatably supported in a case; a carrier formed in a hollow cone-like-shape with a trapezoid cross section in which an outer diameter in an output side is smaller than an outer diameter in an input side, an opening is formed in an outer periphery of the cone, and an output-side end portion of the input shaft is fixed to an outer side surface of a bottom section of the carrier; a planetary friction gear which is rotatably arranged in an opening of the carrier including, in an order from an input side, a first tapered roller, a second tapered roller, and a third tapered roller on a rotating shaft inclined against an axis of the input shaft so as to integrally rotate with the rotating shaft; a sun roller, provided on a same line as the input shaft, which is in contact with the first tapered roller and the third tapered roller, and thereby rotates; a ring roller, provided on a same line as the input shaft, of which inner circumferential surface is in contact with the third tapered roller, and thereby rotates; an output shaft, provided spaced from an output-side end portion of the ring roller on a same line as the input shaft, which is rotatably supported in the case; a loading section including a rolling body, the rolling body pressing the ring roller and the output shaft in an axial direction when a torque differential arises between the ring roller and the output shaft and being provided in a tapered-shape groove formed between the ring roller and the output shaft; and a transmission ring, provided movable in an axial direction of the input shaft, of which inner circumferential surface is in contact with at least a portion of an outer periphery surface of the second tapered roller, thereby allowing the planetary friction gear to spin, characterized in that the planetary friction gear continuously variable transmission further comprises: an input-side support section formed by notching a portion of an outer periphery of a bottom section of the carrier, which rotatably supports an input-side end portion of the rotating shaft of the planetary friction gear. an input shaft which is rotatably supported in a case; a carrier formed in a hollow cone-like-shape with a trapezoid cross section in which an outer diameter in an output side is smaller than an outer diameter in an input side, an opening is formed in an outer periphery of the cone, and an output-side end portion of the input shaft is fixed to an outer side surface of a bottom section of the carrier; a planetary friction gear which is rotatably arranged in an opening of the carrier including, in an order from an input side, a first tapered roller, a second tapered roller, and a third tapered roller on a rotating shaft inclined against an axis of the input shaft so as to integrally rotate with the rotating shaft; a sun roller, provided on a same line as the input shaft, which is in contact with the first tapered roller and the third tapered roller, and thereby rotates; a ring roller, provided on a same line as the input shaft, of which inner circumferential surface is in contact with the third tapered roller, and thereby rotates; an output shaft, provided spaced from an output-side end portion of the ring roller on a same line as the input shaft, which is rotatably supported in the case; a loading section including a rolling body, the rolling body pressing the ring roller and the output shaft in an axial direction when a torque differential arises between the ring roller and the output shaft and being provided in a tapered-shape groove formed between the ring roller and the output shaft; and a transmission ring, provided movable in an axial direction of the input shaft, of which inner circumferential surface is in contact with at least a portion of an outer periphery surface of the second tapered roller, thereby allowing the planetary friction gear to spin, characterized in that the planetary friction gear continuously variable transmission further comprises: an input-side support section formed by notching a portion of an outer periphery of a bottom section of the carrier, which rotatably supports an input-side end portion of the rotating shaft of the planetary friction gear.
