Abstract: A mounting equipment for mounting an object on a mount base component having a hollow portion of approximately circular cross section, which is less susceptible to damage and requires smaller number of parts, includes a expandable nut, a shaft portion to be engaged with the object, and a nut and a screw for drawing the expandable nut and shaft portion close to each other. When the screw is turned with the equipment inserted to the inside of the cylindrical component, the expandable nut and the shaft portion are drawn close to each other, and the shaft portion is inserted to expandable nut so that expandable nut is expanded outward. Thus, part of the expandable nut is brought into pressure contact with an inner wall of the cylindrical component, and hence object is mounted onto the cylindrical component.

Abstract: 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.
