PROBLEM TO BE SOLVED: To provide an engine torque control device capable of accurately establishing target torque close to actual torque by converting air quantity for maintaining idling speed which has not been considered at a time of establishment of the target torque into torque and adding the same to the target torque determined by demand of an operator and engine load. SOLUTION: This device is provided with a target torque establishing means S1 establishing the target torque of the engine according to demand of the operator and engine load, an idling speed maintaining means establishing air quantity necessary for maintaining engine idling speed, a target torque compensation means S3 compensating the target torque by converting air quantity increased by the idling speed maintaining means when an automatic transmission is switched from a neutral range to another range into torque and adding the same to the target torque, a transmission demand torque establishing means S4 establishing demand torque of the engine according to the target torque before the compensation and demand from the automatic transmission, and a torque control means selecting either of the target torque establishing means S1 or the transmission demand torque establishing means S4 and controlling to generate selected torque.
