(57) [Summary] [PROBLEMS] Even if a finger holding a barrel of a writing instrument has a reduced gripping force, the user holds the writing instrument as desired so that the finger does not slide toward the distal end of the barrel. An object of the present invention is to provide a cap-type writing instrument to which means for preventing a finger from slipping toward the distal end side of a shaft cylinder can be attached. The present invention relates to a cap-type writing instrument in which a cap is detachably mounted on a shaft cylinder having a grip portion provided with a non-slip irregularity portion or an elastic body, wherein the cap portion is detachably mounted. An outwardly protruding convex portion is formed on the outer peripheral surface of the shaft cylinder behind the elastic body, and the cap is engaged with the shaft tube by engaging a tip opening for mounting the cap shaft tube on the convex portion. It can be detachably mounted in a substantially vertical shape.

As described above, the fingers holding the barrel of the writing instrument should be prevented from slipping toward the tip of the barrel.
Even if the writing implement has an uneven portion for slip prevention formed on the grip portion of the shaft cylinder, or an elastic body is attached, when writing with high writing pressure for a long time, the writing implement is proportional to the writing pressure. Since it is necessary to firmly grip the gripping portion of the writing instrument, the gripping force of the finger holding the writing instrument may be reduced due to fatigue and the finger may slip.

In order to solve such a problem, a concave portion corresponding to a finger to be clamped is formed in the grip portion, or an elastic body provided with the concave portion is attached to the grip portion, or No. 7-26180. As described in the publication,
Attach the "writing aid lever" to the writing instrument, and touch or pinch the tip of the handle of the writing assistance lever to the part other than the fingertip that holds the writing instrument so that the force of the fingertip holding the writing instrument is applied to the tip of the writing assistance lever. To reduce the fatigue of the fingertips that have writing implements, and registered utility model No. 30
A holder member that comes into contact with a finger or a palm is proposed, as in "Grip-holding auxiliary stationery for calligraphy" described in Japanese Patent No. 17630. However, in such a case, the shortcoming is that it is rather difficult to write when writing in a short time such as writing a memo.
