Claims

[Scope of utility model registration request]

(1) In a knock-type mechanical pencil in which a lead storage tube is slidably mounted inside the barrel, and an eraser is removably fitted to the end opening of the lead storage tube, A bullet piece is formed on the inner wall surface, which gradually inclines toward the axis in the distal direction, and a locking protrusion is formed on the inner mortar of the bullet piece, and a guide part that expands for observation in the distal direction is formed at the distal end. A locking member is fixed, and the distal end of the elastic piece is brought into contact with or close to the outer circumferential surface of the distal end of the lead storage cylinder, and a locking part is provided on the outer circumferential surface of the lead storage cylinder to which the locking protrusion is engaged. It is formed on the distal side of the locking protrusion so that when the knock tube is fitted onto the end of the core storage cylinder, the locking between the locking protrusion of the locking member and the locking part of the core storage cylinder is released. A knock-type mechanical pencil.

(2) The knock-type mechanical pencil according to claim 1 of the utility model registration claim, wherein the locking portion of the lead storage cylinder is an annular protrusion.

(3) A narrowed portion is formed on the distal side of the locking portion of the lead storage cylinder, and the tip of the elastic piece of the locking member is brought into contact with or close to the narrowed portion. Item 2 knock type mechanical pencil.
