Abstract:
An object is to provide a badminton racket capable of easily achieving different performance properties on both sides of the hitting surface easily. A racket includes a frame which extends annularly, a grip, and a string which is stretched across the frame to form a hitting surface on both sides of the frame. The frame is formed to make the front surface portion and the back surface portion thereof asymmetrical in shape in a cross sectional view taken along a plane orthogonal to the extension direction of the frame. The formation of the frame into such an asymmetrical shape makes it possible to change performance properties on shuttlecock hitting between the front and back sides of the hitting surface at the time of hitting the shuttlecock, thus making it possible for the player to obtain two difference capabilities with the single racket simply by changing his or her grip.
