  "textContent": "An electric vehicle includes a non-drive wheel, a pair of right and left drive wheels 35R and 35L provided separately from the non-drive wheel, a support mechanism for supporting the pair of drive wheels to be vertically movable, a pair of motors 33R and 33L corresponding to the pair of drive wheels, respectively, and a controller 81 for varying a difference between motor currents IMR and IML led to the pair of motors 33R and 33L, respectively. With this construction, the controller 81 varies an output difference between the motors 33R and 33L, thereby to be able to rotate each of the wheels 35R and 35L with appropriate torque. Therefore, even when the vehicle body is leaned, a lean angle of the vehicle body can be stabilized.",
