PROBLEM TO BE SOLVED: To solve problems that a desired excellent feel of holding and a property of preventing slippage in writing are not obtained in some cases and that it is rather difficult to attain the required property of preventing the slippage and to maintain the excellent feel of holding at the same time, in a prior art wherein projecting portions are provided in a holder tube and these portions are fitted in through holes formed in a grip and are exposed outside so as to fix the grip of a soft material surely on the holder tube and to make the external appearance decorative. SOLUTION: The projecting portions lower in height than the outer surface of the grip are provided in the outer peripheral part of a holder tube, while hole portions in the same shape as the projecting portions are formed in the grip and fitted on the projecting portions, and recessed penetrating portions having a depth reaching the top faces of the projecting portions from the outer surface of the grip are formed in the grip, whereby a holding part is formed. In another way, second non-penetrating recessed portions are formed further at positions adjacent to the recessed penetrating portions of the grip, so as to form the holding part. |
