PURPOSE: To make possible to master an ideal swing locus, by holding a soft rail in a loop shape by plural adjustable support element, mounting slidably a carriage to the rail, and settling a golf club shaft to the carriage. CONSTITUTION: A soft rail 10 is supported in a loop shape by plural supports 11∼17, and upper part of the support is extendable against under part 22. The soft rail 10 can be fixed to a rod 41 on the support 13∼17 with nut 43. A carriage 50 is freely slidable mounted on the rail 10, and a device 60 to settle a golf club shaft 70 is fixed at middle portion in the lengthwise direction of connecting bar of the carriage 50. Guides 80, 82 are fixed by elements 76, 78 and positions of and distance between the guides 80, 82 can be changed by a golfer's frame. When the golfer 90 swings at the center of the supports 11∼17 and between the guides 80, 82, the carriage 50 freely slides along the rail 10, and an ideal locus is determined automatically.
