Is required. The positional relationship among the golf club, stance, and golf ball used varies from person to person depending on height, flexibility, arm length, and the like. By the way, for beginners and intermediate golfers with inexperienced swing forms, the positional relationship of the golf club, stance, and golf ball used varies from shot to shot, so each shot cannot be impacted with confidence. The trajectory is different and the golf ball cannot be hit at a desired position.

Therefore, various types of golf stance correctors and golf stance indicating instruments used in golf driving ranges have been conventionally proposed. In such a golf stance corrector and a golf stance indicator, a flight direction indicator of a golf ball and a set position indicator of a golf ball are fixed in a state of being orthogonal to each other (for example, Japanese Patent Laid-Open No. Hei 7 (1999) -107242). No. 100237), a device which is made to be in an orthogonal state at the time of use and is maintained in the orthogonal state using a fixing metal fitting (Japanese Patent Laid-Open No. 9-248359), and an orthogonal setting mechanism that rotates in an orthogonal portion.
