Abstract:
1. A grip end bottom weighting structure, wherein: a grip end bottom weight is removably mounted on a grip end of a ball-hitting implement, said grip end bottom weight being characterized in that a soft material, capable of absorbing impact vibrations and in composite integration with a loading member composed of a high specific gravity substance, is integrally formed so as to have axially symmetric wall thickness in cross section and to be mounted by elastically deforming a body component thereof in a mounting hole formed in a grip end bottom of said ball-hitting implement, with at least half of said body component of said soft material protruding from said grip end bottom when mounted; a moment of inertia around center of gravity is increased at a time a ball is hit; and an impact vibration is suppressed, absorbed or attenuated.
