ABSTRACT:
The tire for automobiles being measured is loaded in advance by the load applying means and the drum is driven to rotate the tire. A displacement of the rotatable shaft produced in response to a variation in the radial force acting between the tire and the drum is detected as a displacement of the movable member. The movable member is movable with respect to the drum about a fulcrum which lies in or is located in the vicinity of a plane including a surface in which the drum and the tire are held against each other. Thus any influence by a moment due to a lateral force imposed on the tire can be eliminated, and the apparatus can measure a radial force variation with precision.
