PROBLEM TO BE SOLVED: To provide a gripping part deforming to the shape of the finger tips gripping and providing gripping feeling with sturdiness to solve the problems wherein a gripping part constituted by sealing a flexible material, a gel-like material, or gas inside of the same arbitrarily deforms thereby is not sturdy and too soft and gives poor writing feeling, the touch feeling of the inside barrel is transmitted to the finger tips by deforming even in the case of arranging fine solid bodies in the space and forms sturdy gripping part, causing pain and unpleasant feeling.SOLUTION: In the barrel 1 in which the space is formed inside of the same by arranging at least an inner layer 3 and an outer layer 4 and arranging and/or integrally forming the gripping portion 2 arranging fine solid bodies 5 in the space, the thicknesses of the inner layer and/or the outer layer of the gripping part are changed.COPYRIGHT: (C)2009,JPO&INPIT【課題】内部に可撓性材料、ゲル状物質や気体を封入した把持部は任意に変形してしまうため腰がなく柔らかすぎて筆記感が悪いという欠点があった。また、空間に微細な固体を配し腰がある把持部とした場合でも、変形によって内部の軸体の触感が指先に伝わってしまい、痛みや違和感につながっていた。そこで、握った指先の形状に変形すると共に、腰のある把持感が得られる軸体の把持部を提供する。【解決手段】少なくとも内層3と外層4を設けることで内部に空間を設け、この空間に微細な固体5を配した把持部2を配置及び/または一体に設けた軸体1において、把持部の内層及び/または外層の厚さを変化させた軸体。【選択図】図1
