る可変速プーリー。A carrier rotatably supports a plurality of planetary gears at circumferentially spaced positions, and a sun gear and a ring gear that mesh with the planetary gears, one of the carrier, sun gear, and ring gear is used as an input member, and any other than the input member is provided. A one-way clutch is inserted between any two of the carrier, sun gear, and ring gear, and a one-way clutch is inserted between any two of the carrier, sun gear, and ring gear. In a variable speed pulley in which a space in which a meshing portion of a ring gear is located is hermetically filled with lubricant, a communication hole that communicates the inside of the sealed space to the outside of the sealed space extends in a radial direction to either the sun gear, the ring gear, or the carrier. The valve body is provided by being pressed by a spring against a valve seat formed at a radially inner end of the communication hole, so that the sealed space communicates with the outside through the communication hole at high rotation speeds. A variable speed pulley characterized by:
