Abstract
Two axle-side linking portions and two wheel-side linking portions are included in a rotation body. They are alternately arranged in four positions that are disposed, with equal intervals, along a circumference of a coaxial circle within the rotation body. Four regions located between the axle-side linking portions and the wheel-side linking portions are formed by an elastically deformable member. Further, four ceramic load sensors are arranged respectively in middle positions of the four regions along the coaxial circle. Force acting on a tire is thereby detected only from detection values by a load sensor group of the four load sensors.
