ABSTRACT:
A weight that is composed of a composite of a soft material and a loading member which is a high specific gravity substance and that is mounted on a grip end bottom of a ball-hitting implement, allowing the loading member to be divided into an internal weighting element and an external weighting element; and a grip end bottom weighting structure that uses this weight, in which the center of gravity is shifted closer to the portion grasped by hand, and the node of vibration on the grip is shifted to the grip fulcrum. When mounted, the loading member is disposed on either side of the grip end member, with soft material region interposed therebetween. The weight is at least flexible enough to be easily mounted and to be adjusted in balance, and it will not come off during play. This makes the ball-hitting implement head-light (grip-heavy) just prior to impact, which improves the player's swing or stroke, and also increases the moment of inertia around the center of gravity at the instant of impact and further suppresses or absorbs (attenuates) the vibration caused by impact.
