PROBLEM TO BE SOLVED: To apply uniform pressure onto fingers by furnishing a fluid storage part capable of being elastically deformed through finger force supporting the writing implements on the outer surface of a cylindrical main body fixed on the grip member of writing implements. SOLUTION: The grip member 10 includes a substantially cylindrical main body 11 formed into a plural structure and a fluid storage part 20 capable of being elastically deformed through finger force supporting the writing implement 30 on the outer surface thereof. The main body 11 is formed by the use of flexible vinylchloride or synthetic rubber and by sealing air between the outer surface and the inner surface. Also, a crumbling preventive functioning part 21 is provided at the fluid storage part 20 for preventing the partial elastic deformation of the fluid storage part 20 by controlling the movement of air. The fluid storage part 20 contacts fingers holding the writing implements 30 so that air in the interior moves and is deformed, and an area in the part contacting fingers adds to. Also, even in a deformed state, since the inner pressure of the fluid storage part 20 becomes equal, uniform pressure is applied on the entirety of one finger contacting the fluid storage part 20. |
