PURPOSE: A swing practice device for golf is provided to obtain a practice effect by allowing a user to recognize and correct his or her swing posture. CONSTITUTION: A swing practice device (100) for golf comprises a grip (101), a tubular outer bar (102), and an inner bar. The inner bar is combined with the inner side of the outer bar to be withdrawn by centrifugal force generated by a correct swing. A hanging protrusion for preventing the inner bar from being separated from the outer bar is formed on the front and inside of the inner bar and outer bar. A centrifugal force modulator (105) is installed on the front of the outer bar and inner bar and controls power for withdrawing the inner bar corresponding to centrifugal force according to the swing speed of a user.
