A device for detecting load torque on an electric motor, adapted for use for a device for rotating a predetermined load by the motor. The device for detecting load torque can appropriately and highly accurately detect reaction of such a load, or load torque, acting on the drive output shaft of the motor. The motor is fixed to an external casing, which is a specific holding section or a stationary section, to facilitate production of the device, and a support structure is stably placed. The drive output shaft (14) is projected from one end of a housing of the motor (10), a sleeve body (16) is placed so as to surround the drive output shaft, a flange (18) is formed at one end of the sleeve body, and the flange is fixed to the one end of the housing. The other end of the sleeve body is integrally formed as an internal gear section (22) of a reduction mechanism (20) having a planetary gear (21). A strain gauge (24) is attached to the outer periphery of the sleeve body. |
