Claims

[Scope of utility model registration request]

The end cylinder has a locking step formed in a hole penetrating in the axial direction, and the clutch cylinder has a center hole in the shaft cylinder connected to the tip. A clamping head that can be expanded and contracted to engage with the receiving member/clutch cylinder that comes into contact with it, a tubular part that is inserted into the center hole of the clutch cylinder and the receiving member, and a collar part that is connected to the end of the tubular part. In a mechanical pencil, a mechanical pencil is equipped with a chuck and a feeding member consisting of a spring that is inserted into the tubular part of the chuck and stretched between the receiving member and the flange, so that the lead is fed out by the forward expansion of the chuck. The feeding member is urged toward the tip by a buffer spring whose one end is in contact with the distal end of the receiving member, and the tip of the receiving member is brought into contact with the end of the inner protruding edge formed on the inner peripheral surface of the shaft cylinder. A flange is formed on the outer periphery of the gripping head of the chuck, and a plate-shaped disengagement member is tilted on the gripping head located between the end of the flange and the tip of the clutch cylinder. The release member has an insertion hole in the center that is smaller than the outer diameter of the clutch cylinder and has an inner diameter that is approximately equal to or larger than the outer diameter when the clamping head is expanded. The part is provided with a locking part protruding outwardly that abuts against the locking step at the tip of the inner projecting edge and the locking step on the end tube, and at the diametrical position of the insertion hole. A mechanical pencil characterized by having a protruding fulcrum part that comes into contact with the end surface.
