PROBLEM TO BE SOLVED: To release ions from a back surface of a second chair when it is determined that a first chair is faced to the back surface of the second chair. SOLUTION: The ion control vehicle includes a plurality of chairs 70; an ion generator 40 for releasing ions from any one of back surface of the plurality of chairs 70; a rotation shaft 52 for changing the direction of any one chair of the plurality of chairs 70; a direction sensor 50 for detecting the direction of the chair 70 changed by the rotation shaft 52; a control part 20 for determining whether or not the first chair, i.e., any one of the plurality of chairs 70 is faced to the back surface of the second chair positioned in a front of the first chair and generating the ions by the ion generator 40 by comparing the directions of the chairs 70 with each other and controlling the ion generator 40 such that the ions are released from the back surface of the second chair when it determines that the first chair is faced to the back surface of the second chair; and a running traveling part 80.
