Since the cap must be removed before use, it is troublesome to have to remove the cap each time it is used, and it is easy to lose the cap. There are also known writing instruments in which the eraser stored in the barrel can be moved out and out of the barrel by rotating the barrel, but in order to draw out the eraser by rotating the barrel, a threaded groove or the like is formed on the inner surface of the barrel. Many of the formed products are troublesome and expensive to manufacture, have a large number of parts, are prone to failure, and are difficult to repair and adjust.

An example of application to a mechanical pencil is shown. In the figure, a ↓ sea urchin cap (3) protruding from the shaft tube (1) is fitted in front of the connector (2) which is press-fitted, screwed or otherwise fixed into the shaft tube (1). There is a lead core (4) inside the cap (3).
A breaker (5 pins) made of elastic material is provided to hold the lead core.A lead core feeding mechanism is attached to the connector (2).In other words, a chuck (7 pins) is installed in front of the stepped portion (6). ) and the fastener (8) are attached, and the chunk (
A core tank (9) is fixed to the rear of the connector (7), and a spring α is installed between the core tank (9) and the stepped portion (6) of the connector (2).
Q is provided. The core tank (9) has a polygonal outer shape as shown in Fig. 3, and is fitted into the polygonal mounting hole 0υ of the connector (2) so as to be movable in the axial direction. It is fitted.
なお、溝と突起その他適宜の構成により軸方向へ移動可

The rotating sleeve (to) with A) formed on its inner surface has a locking edge at the tip as shown in FIG. The receiving portion α1 of the holder is formed so that it can slide until the two come into contact with each other. As shown in FIG. 2, a ring piece is fitted to the rear end of the rotating sleeve.

えばよい。In use, when the above-mentioned structure is used, when the rotating sleeve is rotated, the holder is prevented from rotating, so it moves in the axial direction while being guided by the thread (a) and the thread groove (to). However, the eraser (A) protrudes from the rotating sleeve 4 and can be used. When turned in the opposite direction, the eraser (4) is stored in the rotating sleeve (a). Furthermore, the movement of the holder is limited because the protrusion Qal touches the front end of the rotating sleeve (O).Also, if you press the rotating sleeve (C), you can press the lead lead (4 ), or
It can be withdrawn. The lead core can be replenished by removing the eraser (1) from the receiving part α9 of the holder □□□.
