The exhaust gas recirculation valve device of the present invention is provided with a motor main body which drives a valve by a valve rod in direction of opening or closing, and a motor holder which covers the lower opening of the motor main body . A circular groove is formed on one of the upper section of the motor holder and the lower opening of the motor main body and a protrusion which fits into the circular groove is formed on the other of the upper section of the motor holder and the lower opening of the motor main body . A liquid sealant layer is disposed between upper face which is the top of the protrusion and the lower face which is the bottom of the circular groove facing the upper face

Exhaust gas recirculating valve device

An exhaust gas recirculation valve device is provided with a motor shaft, a stepping motor main body driving the motor shaft, a valve shaft having a tip functioning as a proximal end which faces one end of the motor shaft and a distal end provided with a valve, a spring pushing the valve shaft in a closing direction, and a spring holder retaining the spring. In the case that the valve is cloned, the tip of the valve shaft and the spring holder are caulked together at a distance between the tip of the valve shaft and the one end of the motor shaft so that a distance between the facing ends of the motor shaft and the valve shaft is equivalent to a difference between a stroke of the motor shaft of the stepping motor main body and a stroke of the valve on opening.
