PROBLEM TO BE SOLVED: To provide a movable spectator stand, without wholly impairing soundness of a uniform and seamless athletic sports track. SOLUTION: This movable spectator stand 1 is arranged in an athletic sports field with a plurality of seats 2 and a base part 3 supporting these seats, and can move in the inside-outside directions, and is switched between a retreat state of placing the whole on the outside of the track B and an advance state of grounding a rear part on the outside of the track B and grounding a front part on the inside of the track B by the movement, and is constituted so that the base part 3 is not contacted with both a surface of the track B and any object on the track B in both states of including moving time.
