Abstract
Abstract A golf swing training device actuated by golf club back swing and down swing by the golfer and comprising arm angle detecting means which includes a support member mounted on a golfer's arm for movement therewith as the golfer makes a swing, a direction indicator mounted on the support member and for indicating a direction in a plane including the gravitational direction or a direction at a fixed angle to the gravitational direction, and a direction indicator detecting means for detecting the direction indicator when an angular position set as desired with respect to the direction indicator is reached by the support member, and a means for informing the golfer of the arm angle detected by the arm angle detecting means through the controller. The informing means including means for initiating a signal and transmitting such signal to the golfer or knee, waist and/or ankle of the golfer for causing slight twisting of the golfer's body in a down-swing start direction and starting down swing.
