Racket frame |
摘要 |
A frame body (2) is formed separately from a yoke (10) connecting right and left parts of the frame body (2) to each other. The yoke (10) and the frame body (2) are connected to each other by a mechanical connection means, with both ends of the yoke (10) in contact with the right and left parts of the frame body (2) in an area of not less than 10 cm2. A shear force generated when the racket frame (1) deforms is collectively applied to a connection surface of the frame body (2) and that of the yoke (10) to increase a vibration-damping performance of the racket frame (1).
