A roller 26 for applying a load to a tire 44 of a rear wheel as a drive wheel is rotatably supported by support frames 30 through a roller shaft 24. The support frames 30 are rotatable about a fixing shaft 28 penetrating their ends. A support portion 29 supporting the fixing shaft 28 is fixed to a load applying device stand 2 to be inserted in a rear frame 22. A coil spring 34 is provided between a fixing plate 32 fixed to the load applying device stand 2 and a transverse plate 31 of the support frames 30. A pedal clamp 38 to be engaged with the plate 31 in a state of the coil spring 34 being compressed is rotatably provided on the load applying device stand 2. When a load applying device is to be used, the position of the load applying device stand 2 is adjusted so that the roller 26 slightly contacts the rear wheel tire 44 with the pedal clamp 38 being engaged with the plate 31. Then, the pedal clamp 38 is disengaged therefrom and the roller 26 applies a predetermined contact force as a load to the rear wheel tire 44.
