In a folding mobile phone (folding portable electronic device), a cam mechanism (support mechanism) includes a first guide groove, a second guide groove, a first guide pin engaged into the first guide groove, a second guide pin engaged into the second guide groove, and a link member connecting the first and second guide pins. The cam mechanism supports a liquid crystal display part to allow the liquid crystal display part to turn clockwise and counterclockwise as viewed from the front, thereby allowing the liquid crystal display part to be changed between a vertical position and a horizontal position. Furthermore, the cam mechanism includes an urging mechanism urging the second guide pin to allow the liquid crystal display part to reach the vertical or horizontal position in either turning direction.

摘要:
An input shaft that transmits torque to rear wheels is formed integrally with a first roller. An output shaft that directs torque to front wheels is formed integrally with a second roller. An inter-roller-axis distance is set smaller than a sum of semidiameters of the rollers, so as to press the rollers 31, 32 in a radial direction into pressing contact with one another, so that a part of torque from the input shaft to the rear wheels is directed through the rollers and the output shaft to the front wheels. The inter-roller-axis distance is set so as to set an inter-roller radial pressing force so that a maximum distribution condition maximum roller-transmitted torque under a front wheel torque maximum distribution condition, which is determined by the radial pressing force, is below a front wheel maximum distribution torque based on an assumption that a maximum torque is transmitted to the input shaft under the front wheel torque maximum distribution condition.
