A chassis dynamometer includes a flat-belt mechanism configured such that a drive wheel of a vehicle is placed thereon, which includes a rotating member configured to be rotated by rotation of the drive wheel, a bearing portion configured to rotatably support the rotating member, a motor configured to apply a resistance to the rotation of the rotating member, and a bearing supporting member to which a housing of the bearing portion and the motor are fixed, a base configured to support the bearing supporting member from beneath the bearing supporting member, a plurality of three-component force sensors arranged between the bearing supporting member and the base to measure a force transmitted from the drive wheel to the flat-belt mechanism, and a computing unit configured to compute moments with respect to three axes based on measurement results of the plurality of three-component force sensors.
