Abstract
Performance of a racket can be adjusted. A racket includes a grip, an annular frame that is provided with a plurality of through holes that penetrate from an inner circumferential face to an outer circumferential face, and a shaft that connects the grip and the frame in a shaft axis direction, the frame having a rear end side attachment part, on the outer circumferential face of the frame and on a side closer to the shaft in the shaft axis direction, where there is mounted a rear end side attachment to which a string tensely provided to the frame is routed, and the rear end side attachment being made of a material different from the frame.
Claims6
A racket comprising:
- a grip;
- an annular frame that is provided with a plurality of through holes that penetrate from an inner circumferential face to an outer circumferential face;
- and
- a shaft that connects the grip and the frame in a shaft axis direction,
- the frame having:
- two rear end side weight variable component attachment parts, disposed on the outer circumferential face of the frame and on a side closer to the shaft in the shaft axis direction, where there are respectively mounted at different positions on the outer circumferential face two rear end side weight variable component attachments through which a tensioned string is routed, and where the two rear end side weight variable component attachments are made of a material different from the frame, and
- two tip end side weight variable component attachment parts, disposed on the outer circumferential face of the frame and one a side opposite the side closer to the shaft in the shaft axis direction, where there are respectively mounted at different positions on the outer circumferential face two tip end side weight variable components through which a tensioned string is routed, and where the two tip end side weight variable components are made of a material different from the frame,
- wherein a shortest distance to each of the rear end side weight variable component attachment parts from a center line of the racket being shorter than a shortest distance to each of the tip end side weight variable component attachment parts from the center line, the center line extending along the shaft axis direction.
