Claims

[Scope of utility model registration request]

In a push-out writing instrument in which a lead case provided in the barrel is always pressed in the retracting direction by a retraction spring, and a chuck and a chuck ring are arranged at the front of the lead case, the chuck is separated from the lead case and the chuck side of the lead case is The end portion and the end portion of the chuck ring on the side of the core case are slidably fitted into each other, and a compression spring with the weakest elastic force is interposed between the chuck and the chuck ring. An operating member for feeding the writing lead is provided in the tip which is brought into contact with the chuck side end of the lead case and is removably connected to the barrel, and the operating member is attached to the flange of the tube body having a lead holding ring. An operating member that has a protruding edge and an operating piece that can be operated from the barrel or tip, and has an elastic force intermediate between that of a retraction spring and a push spring. A mechanical pencil with a push-back spring interposed between the inside of the tip and the rim.゛
