Drive disks are configured to rotate a main wheel by applying a frictional force thereto. Each of the drive disks includes a base and a plurality of rollers. The base includes a first sheet metal member and a second sheet metal member. The first sheet metal member includes a first central part and a plurality of first arm parts. The second sheet metal member includes a second central part and a plurality of second arm parts. Each of the rollers has a first end and a second end. Each of the first arm parts includes a first supporting part and a second supporting part. Each of the second arm parts includes a third supporting part and a fourth supporting part. The first supporting part and the second supporting part are inclined to each other. The third supporting part and the fourth supporting part are inclined to each other.

An automatic guided vehicle according to one aspect of the present invention moves a trolley including a trolley body, wheels attached to the trolley body, and a section to be connected which is provided on the lower surface of the trolley body. The automatic guided vehicle is provided with: a vehicle body; drive wheels attached to the vehicle body; and a connection mechanism which is connected to the trolley, wherein the connection mechanism includes a connecting section disposed on an upper side of the upper surface of the vehicle body so as to be movable horizontally in a first direction, and includes a drive apparatus which moves the connecting section in the first direction and connects the connecting section to the section to be connected.

Automatic guided vehicle and method for controlling automatic guided vehicle

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.

Continuously variable transmission and bicycle

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.
