Abstract
A frame body ( ) is formed separately from a yoke ( ) connecting right and left parts of the frame body ( ) to each other. The yoke ( ) and the frame body ( ) are connected to each other by a mechanical connection means, with both ends of the yoke ( ) in contact with the right and left parts of the frame body ( ) in an area of not less than 10 cm (1.6 in ). A shear force generated when the racket frame ( ) deforms is collectively applied to a connection surface of the frame body ( ) and that of the yoke ( ) to increase a vibration-damping performance of the racket frame ( ).
