PROBLEM TO BE SOLVED: To provide a belt tension regulating device of an engine for improving durability of components of a supporting point and reliability of the belt tension regulating device, by reducing an action force of a connection arm which is connected with an automatic tensioner and bending moment generated by the action force. SOLUTION: The belt tension regulating device of an engine comprises: an auxiliaries driving pulley rotary-driving auxiliaries by torque of a crank pulley; an actuator connected, through the connection arm, with the tension pulley wound in the middle of a belt; and having the automatic tensioner changing a rotation center position of a tension pulley by movement of the actuator to regulate tension of the belt. A reinforcement member for supporting a force acting on the vicinity of the supporting point is suspended between either of a fixed end of the actuator or an engine main body part and the supporting point of the connection arm, so that the reinforcement member cancels out the force acting on the vicinity of the supporting part.
