PURPOSE:To facilitate a connecting operation, by providing the coupling of a tester with a pair of driving pins which correspond to a connecting projection on the front end of the rotor of a tested machine and are urged by springs so as to project to pinch the connecting projection on both the sides thereof in the circumferential direction of the rotor. CONSTITUTION:A plurality of connecting projections 21 are secured on the rotor 1 of a tested machine near the periphery of the front end of the rotor and located at equal intervals in the circumferential direction of the rotor. A coupling 24, which is connected to the tested machine, is fitted with a pair of guide bushes 25 near the periphery of the coupling. The guide bushes 25 are located in positions to pinch the connecting projection 21 on both the sides thereof in the circumferential direction. Driving pins 26, 27 are supported in the guide bushes 25, respectively, so that the driving pins can be protruded and retracted in the axial directions thereof. A receiving surface 26a, an inclination pushing surface 27a and sloping surfaces 26b, 27b are provided on the front ends of the driving pins 26, 27. |
