摘要： A tire uniformity measuring apparatus having: a drum for rotating a tire; an oscillating member disposed parallel to a drum rotating shaft and pivotally supported on a machine base through a fulcrum; a movable member disposed in parallel to the drum rotating shaft in the plane including the drum rotating shaft and a tire rotating shaft, the movable member being laterally movable in response to a load acting on the tire in a lateral direction perpendicular to the radial direction of the tire; a load applying member for applying in advance a predetermined load to the tire; and a displacement detecting member for detecting as a displacement of the movable member the displacement of the tire rotating shaft which is dependent on variation in the lateral load; thereby detecting a variation in the lateral load of the tire. The apparatus may comprise a further movable member which is a shaft member constituting the fulcrum, the movable member being slidably movable along the longitudinal axis only in response to a variation in the tangential load, and a further displacement detecting member for detecting a displacement of the movable member, thereby detecting a variation in the tangential load acting on the tire.
