<p><P>PROBLEM TO BE SOLVED: To provide a table tennis racket which is excellent both in repulsion performance and in spin performance. <P>SOLUTION: The solid rubber 11 of the table tennis racket 1 has an area A and an area B. The area A is formed from a rubber composition including natural rubber or polyisoprene of more than 70 percent by mass in a base polymer. The area B is formed from a rubber composition including polybutadiene of more than 40 percent by mass in the base polymer. The area B contains a point in which a length direction distance from a tip is Lb and a width direction distance from a center line CL is Wb. Values of the Lb is 0.40 times the face length L. Values of the Wb is 0.12 times the width W. The area contains a point in which the length direction distance from the tip is La. Values of the La is 0.25 times the face length L. The area of the area A is 10% or more of the whole area of the solid rubber. The area of the area B is 5% or more of the whole area of the solid rubber. <P>COPYRIGHT: (C)2004,JPO</p> |
