To practice a shot at a slope which is set at an optional inclination, i.e., an upslope or a downward slope.

A leg 12 which can control movement toward right and left directions is provided at a lower face of one side of right and left of the first stand 10 having an area enough to have a stance when people mounts on the stand. A leg 12 which can control movement toward right and left directions is provided at a lower face of one side of right and left of the second stand 30 which can set up a dummy golf ball 40. The first stand 10 and the second stand 30 are connected by a joint member 52 so as not to be gotten out of position to right and left directions mutually. An inclination of a slope of shot which is going to be practiced is controlled optionally by changing height of one side of the first stand 10 and the second stand 30 by dint of being moved each leg 12 suitably.
