PROBLEM TO BE SOLVED: To provide a grip which fits well to the hands by deformation on the side slightly inner than the surface while the touch is improved by lessening the deformation of the parts to be directly touched by the hands. SOLUTION: Many long grooves 3b are formed axially on the outside surface 3a of the grip 3. These long grooves 3b are formed of respectively straight opening side grooves 3c and grooves 3d, 3d divided on the inside front end side to an inverted Y shape. The grooves 3d, 3d on the inside front end side inner than the grooves 3c on the opening side of the outside surface 3a are made wider by a spacing (a) in the direction proximate to the grooves 3d on the inside front end side of the other adjacent grooves 3b on both right and left side. Namely, the grooves expanded respectively on the slightly inner layer side of the grooves 3b in both directions proximate to the grooves 3d on the inside front ends side of the right and left grooves 3b are formed. The peripheral walls of the grooves 3c on the opening side of the grooves 3b are formed in proximity to each other in such a manner that these walls are pressed to each other in the state after molding. |
