A power unit comprises: a wave gear speed reducer, a rotary shaft extending in the axial direction; a rotor unit that rotates integrally with the rotary shaft; a stator unit disposed facing the rotor unit; and a motor casing to which the stator unit is secured. The motor casing has a second cover that covers the rotor unit and the stator unit from the other side in the axial direction. The rotary shaft extends toward the other side in the axial direction, penetrates the second cover, and is connected to a cam. The second cover has a support part that extends toward the other side in the axial direction, supports the rotary shaft in a rotatable manner, and is positioned in a flexible cylindrical part of an external gear.

A continuously variable transmission includes an input rotor, an output rotor, a plurality of planetary rollers, a guide member, a movable ring, and an elastic member. The input rotor is arranged to rotate about a main axis at a rotation rate before a speed change. The output rotor is arranged to rotate about the main axis at a rotation rate resulting from the speed change. The planetary rollers are arranged around the main axis, and each planetary roller is capable of rotating about a rotation shaft. The guide member is arranged to restrict positions of both end portions of the rotation shaft. The movable ring is capable of rotating about the main axis between the main axis and the planetary rollers. The movable ring is annular, and is capable of moving in an axial direction. The elastic member is capable of expanding and contracting in the axial direction. Each planetary roller includes a first slanting surface, a second slanting surface, and an annular recessed portion or annular projecting portion. The guide member is arranged to hold the end portions of the rotation shaft at different circumferential positions such that each end portion of the rotation shaft is capable of shifting a position thereof in a radial direction with respect to the main axis. The elastic member is arranged to apply a pressure to the movable ring in the axial direction.

A friction-type continuously variable transmission includes first to third rolling elements of which are annular and is centered on a principal axis, planetary rollers arranged in a circumferential direction about the principal axis, support pins arranged to rotatably support the planetary rollers, and a planetary roller support portion arranged to support each support pin such that the support pin is capable of inclining in a section including the principal axis. Each planetary roller includes a recessed portion in the shape of a circular ring in an outer circumference thereof centered on the support pin. The first rolling element is arranged to make contact with a rolling contact surface of the planetary roller from one side in a radial direction axially below the recessed portion. The first rolling element is arranged to make contact with the rolling contact surface of the planetary roller from the one side in the radial direction axially above the recessed portion. The third rolling element is arranged to make contact with the recessed portion of the planetary roller from an opposite side in the radial direction, and is supported to be capable of moving in a vertical direction relative to the planetary roller support portion.

A molded polymer article comprises a main molded body having on the surface thereof a hydrophilic polymer layer, the article being obtained by polymerizing both a monomer having a hydrophilic group and coated on the surface of a hydrophilic mold, and a polymerizable composition consisting essentially of a monomer and/or oligomer and placed in the mold. The hydrophilic polymer layer has excellent adhesiveness to the main body of the molded polymer article and excellent durability, so that the high hydrophilic property can be maintained, even when the article is exposed to external forces such as friction, over a long period of time. The molded articles are therefore useful as, in particular, contact lenses.
