发明名称 ROD-LIKE OBJECT FOR BALL GAMES AND METHOD FOR USING THE SAME
摘要 A rod-like object for ball games 1 usable for a ball games or practice thereof, the rod-like object 1 comprising a grip 20 on a proximal end side of an elongated main body 10, the main body 10 comprising a first flexible part 12 in which primary deflective deformation occurs along a first imaginary plane, a second flexible part 14 that is provided more toward the proximal end side than the first flexible part 12 is and in which principal deflective deformation occurs along a second imaginary plane, and a highly rigid part 19 interposed between the first flexible part 12 and the second flexible part 14, the first imaginary plane and the second imaginary plane intersecting each other, and the highly rigid part 19 having a flexural rigidity in a direction of the first imaginary plane that is equal to or greater than a flexural rigidity of the second flexible part 14 in the same direction and a flexural rigidity in a direction of the second imaginary plane that is equal to or greater than a flexural rigidity of the first flexible part 12 in the same direction.
