To reduce energy loss to increase power transmission efficiency, as well as to suppress unusual sound resulting from whirling vibration. A driving force transmission mechanism 20 includes a drive unit 220 that generates a rotation force and consists of a motor, as well as an independent rotating mechanism 230 that is disposed between the drive unit 220 and one of a pair of left and right gear mechanisms 210, 210 so as to be connected to the output shaft of the drive unit 220 and has greater kinetic energy than the rotating parts of the gear mechanisms 210, 210. Flexible shafts 233, 234, 235 that rotate by smaller kinetic energy than any of the kinetic energy of the drive unit 220, the kinetic energy of the rotating mechanism 230, and the friction forces and damping forces of the rotating parts of the gear mechanisms 210, 210 connect between the drive unit 220 and rotating mechanism 230, between the rotating mechanism 230 and one gear mechanism 210, and between the drive unit 220 and the other gear mechanism 210.
