PROBLEM TO BE SOLVED: To provide an eddy current type electric dynamometer of simple structure improved in a response characteristic, in the eddy current type electric dynamometer. SOLUTION: An eddy current generating disc D is fixed onto a shaft 21 rotated by a motor (prime mover) 23, and permanent magnet attaching members 111, 112 attached with permanent magnets M1, M2 are attached oscillatably thereto. When the shaft 21 is rotated, the eddy current generating disc D is rotated to generate an eddy current in the eddy current generating disc D by the permanent magnets M1, M2, so as to absorb power. Torque arms 311, 312 are oscillated together with the permanent magnet attaching members 111, 112 to actuate load cells 331, 332. COPYRIGHT: (C)2005,JPO&NCIPI
