PROBLEM TO BE SOLVED: To steadily perform power transmission by friction between a drive roller D and a driven roller S, and to achieve miniaturization of a power transmission mechanism.SOLUTION: A power transmission roller is configured by including: a roller body 2 for coming into contact with a drive roller D and a driven roller S; a swing shaft 3 fixed on a vehicle body side; a swing arm 4 arranged on the inner diameter side of the roller body 2, and provided swingably at the swing shaft 3; a roller bearing 5 for allowing the roller body 2 to rotate freely; and a pair of energization members 6, 6 provided at the swing arm 4, and for energizing the roller bearing 5 so that a contact force with both rollers D, S becomes balanced at a predetermined position between the drive roller D and the driven roller S.SELECTED DRAWING: Figure 1 |
