  "textContent": "An exhaust gas recirculation valve device is prvided with a motor shaft 32, a stepping motor main body 20 driving the motor shaft 32, a valve shaft 6 having a tip 6a functioning as a proximal end which faces one end of the motor shaft 32 and a distal end provided with a valve 8, a spring 10 pushing the valve shaft 6 in a closing direction, and a spring holder 9 retaining the spring 10. In the case that the valve 8 is closed, the tip 6a of the valve shaft 6 and the spring holder 9 are caulked together at a distance between the tip 6a of the valve shaft 6 and the one end of the motor shaft 32 so that a distance L between the facing ends of the motor shaft 32 and the valve shaft 6 is equivalent to a difference between a stroke of the motor shaft 32 of the stepping motor main body 20 and a stroke of the valve on opening.",
