PROBLEM TO BE SOLVED: To provide a running test device for a vehicle for carrying out travelling testing in an environment near to the state of a practical road surface. SOLUTION: The running test device comprises: a pair of first rollers; a first bearing part having a pair of bearings rotatably supporting each of the pair of the first rollers respectively; and a first endless belt stretched to the pair of the rollers, and includes a flat belt mechanism where at least one of tires of the vehicle is contacted on the first endless belt, and the first endless belt is rotated around the pair of the rollers by following rotation of the tire. The tires are supported by the flat belt mechanism. The tires and the first endless belt are brought into contact with each other at an intermediate position between the two rollers constituting the pair of the rollers. In addition, a pair of bearing housings are fixed on a bearing support member, and a load sensor for measuring force transmitted from the tires of the vehicle to the flat belt mechanism is arranged between a base of the travelling testing device for the vehicle and the bearing support member.
