。[Claims for Utility Model Registration] (1) A pseudo ball having substantially the same characteristics as a golf ball, a means for restricting the trajectory of the pseudo ball, and a means for directly controlling the initial velocity of the pseudo ball when the pseudo ball is hit. Alternatively, an impact tester for golf balls, etc., comprising a detection means for indirect detection and a speed indicator for displaying the detection result. (2) The detection means for indirectly detecting the initial velocity of the pseudo ball is fitted into a cylindrical cylinder with closed ends on both sides so as to be movable along the cylindrical cylinder, and has a diameter slightly smaller than the diameter of the cylinder. A speed switch according to claim (1), comprising a spherical sensing mass, means for restraining the sensing mass to the end of the cylinder, and a contact that operates when the sensing mass overcomes the restraining force and moves. Simulated ball impact tester. (3) The detection means that indirectly detects the initial velocity of the pseudo ball includes an acceleration detector installed in the pseudo ball and an integrator that calculates the velocity by time-integrating the acceleration measured by the detector. The simulated ball impact tester according to claim (1), comprising:
