Abstract

PURPOSE: To make a ball holding state satisfactory and to improve controllability by forming left and right symmetric ball holders, which have inclined elements opened toward the outside, for width having a gap so that the left and right inclined elements can not touch a ball stopper. CONSTITUTION: A ball holding hand 1 is composed of left and right symmetric ball holding hand constitutive members 8, and the ball holding hand constitutive member 8 is composed of an inclined element 7 opened toward the outside and a link element 9 vertically formed downward. The link elements 9 of the left and right ball holding hand constitutive members 8 are mutually linked in the state of securing the hollow part of suitable gap, and the left and right inclined elements 7 of the ball holding hand 1 are formed for the width at a degree not to touch ball stoppers 3 and 3'. Even when the outside rather than the ball stoppers 3 and 3' is wider, pitching action is not affected. Namely, since the ball holding hand 1 does not have notched parts 5 and 5' on the sides of a plane, pitching control is not disordered.
