In a secondary air supply device for an engine that supplies secondary air to the exhaust system through the communication passage during idle, the control valve is controlled by exhaust pressure introduced into the control valve through the exhaust pressure passage communicating with the exhaust system. A secondary air supply device for an engine, characterized in that it is provided with an exhaust pressure operating chamber that biases the valve in the valve closing direction.
