ある。(Effects of the Invention) The present invention is configured as described above, in which a small diameter screw cylinder is formed at the tip of the rotary sleeve via a step, and the holder of the holder is fitted in the rotary sleeve to receive the holder. A tubular portion is formed at the tip of the portion to be threadedly engaged with and inserted into the screw cylinder, the rotary sleeve is rotatably attached to the rear end portion of the writing body, and the tubular portion of the holder is axially movable. Since it is prevented from rotating around the cursive body, when the rotating sleeve is rotated, the eraser or the like attached to the receiving portion of the holder can be used by protruding or retracting from the rotating sleeve.
At this time, the protruding position and the retracted position of the eraser are the position where the projection formed on the outer periphery of the tip of the cylindrical part of the holder engages with the end edge of the screw cylinder of the rotary sleeve and the receiving part of the holder is the step of the rotary sleeve. There is no fear that the holder will fall out of the rotary sleeve or sink deeply into the cursive body because it is regulated at the position where it is engaged with the end portion. Since a slit is provided in the holder so that the holder can be bent inward, even if a screw thread is formed on the inner surface of the small-diameter screw cylinder of the rotary sleeve when the holder is fitted to the rotary sleeve, the holder The cylindrical part of can be inserted into the screw party without any problem by bending the tip to reduce the outer diameter of the protruding part, and after the insertion, the protruding part spreads back to the original state. In retaining it can exhibit the effects as described can be assembled easily with the assembly robot or the like, configuration less fault easy, because parts is small,
It is easy to manufacture and assemble, and it can be assembled by attaching a connector to the barrel to support various barrels.
