PROBLEM TO BE SOLVED: To solve problems in a conventional golf practice device in which there is such inconvenience as to change mounting of a practice ball with an arm to a rotating shaft each time when shifting from practice with an iron shape golf club to practice with a wood shape golf club, and also a limited range of installation conditions is narrowed from factors such as selection of installation location, and strength and sizes of a fixing device so that a practice device does not move against hitting vibration and impact with respect to fixation of the golf practice device.SOLUTION: A practice device includes a structure of a shape for connecting multiple golf practice balls with arms at a rotating shaft position, and the golf practice balls with arms are connected at different positions mainly on the rotating shaft. At least two balls can be connected centering on the rotating shaft, if in a balanced arrangement and the practice using golf clubs of different shapes can be performed. The multiple practice balls with arms are connected mainly on the rotating shaft, and thereby the vibration impact acting on the device in the hitting practice is mitigated and the movement and slippage of the practice device when in use can be prevented. |
