摘要： PROBLEM TO BE SOLVED: To detect braking torque more accurately in a disc brake device for rolling stock. SOLUTION: A strain gauge 30 is fitted to a brake caliper of a disc brake device. In a braking torque computing means 40, a detection signal from the strain gauge 30 is multiplied by a proportional coefficient to compute brake torque, and the proportional coefficient is corrected by a proportional coefficient correcting means 41 according to the grade of braking pressure. A correcting strain gauge 35 is provided on the curved part inner peripheral side of the base end of an arm of the brake caliper, and the detection signal from the strain gauge 30 is corrected on the basis of a detection signal from the correcting strain gauge 35 so as to eliminate the influence of strain to the direction to tend to open the arm.
