This transmission comprises: a sun roller (14A) which rotates about the center axis; a plurality of planetary rollers (26A, 26C) which are located in the periphery of the sun roller (14A); an annular internal ring (32A) which is located further toward the outside in the radial direction with respect to the center axis than the plurality of planetary rollers (26A, 26C) and which makes contact with the plurality of planetary rollers (26A, 26C); and a carrier which has a plurality of carrier pins (35A) that support the plurality of planetary rollers (26A, 26C) so that the planetary rollers can turn on their respective axes around the center axis. The plurality of planetary rollers (26A, 26C) each have: an annular outside member (261A, 261C) which has an outer peripheral surface that makes contact with the internal ring (32A) and the sun roller (14A); and an annular inside member (262A) which is located on the inside of the outside member (261A, 261C) and has an inner peripheral surface that is at least partially supported directly or indirectly by the carrier pin (35A). The outside member (261A, 261C) and the inside member (262A) are directly or indirectly fixed to each other, and part of the inner peripheral surface of the outside member (261A, 261C) and part of the outer peripheral surface of the inside member (262A) face each other across a gap.
