Zusammenfassung:	PURPOSE:To detect torque with simple structure by fixing plural permanent magnets on torque transmission flanges respectively fixed on the facing end parts of a driving shaft and a driven shaft and connecting the driving shaft and the driven shaft with magnetic force. CONSTITUTION:Torque transmission flanges 25, 24 are fixed respectively to the mutually facing end parts of the driven shaft 11 and the driving shaft 16 of a drilling machine. Plural permanent magnets 27, 26 are fixed on each of these flanges 25, 24, and transfer torque between the driving shaft 16 and the driven shaft 11 is changed by detecting each phase of these permanent magnets 26, 27 with magnetic sensors 31, 32.
