PROBLEM TO BE SOLVED: To solve the problem in regard to a shaft body provided with a grip part that almost the whole inside of the grip part contacts with the shaft body and this causes a feel of hardness of the shaft body and that even when a space is interposed between the shaft body and the grip part, the grip part contacts partially with the shaft body and therefore the feel of the hardness is brought about only in a portion, on the contrary, and this causes an uncomfortable feeling.SOLUTION: In the shaft body having the grip part formed on the outer periphery of the shaft tube, the grip part is formed of two members of an inner grip member 2 and an annular outer grip member 3 covering the member 2. A space is interposed between the two members by establishing the relation of A<；C<；B when the outer diameter of the inner grip member 2 is defined as A, the outer diameter of an outer peripheral projection 4 of the inner grip member 2 as B and the inner diameter of the annular outer grip member 3 as C, and also the projections 4 are provided at least at two places of the outer periphery of the inner grip member 2 so that they hold the annular outer grip member 3 in between.COPYRIGHT: (C)2008,JPO&INPIT【課題】把持部を設けた軸体では、把持部は把持部内面のほとんどの箇所が軸体に接しており、軸体の硬さを感じるものであった。また、軸体との間に空間を設けた場合にも一部が軸体と接しているため、逆に一部分だけ硬い触感となり違和感が生じるといった問題があった。【解決手段】軸筒の外周に把持部を形成した軸体において、把持部を内部把持部材２とこれを覆う環状外部把持部材３の２部材で形成し、内部把持部材２の外径をＡ、内部把持部材２の外周凸部４の外径をＢ、環状外部把持部材３の内径をＣとした時、Ａ＜Ｃ＜Ｂの関係が成り立つようにすることにより２部材間に空間を設けると共に、内部把持部材２の外周の少なくとも２箇所に凸部４を環状外部把持部材３を挟むように設けた軸体。【選択図】図１
