A training machine for golf swing includes a plurality of magnets provided in the opposite position to the grip; a collision device attachable to the magnets, and adapted to be separated from the magnets and collided with other objects by the centrifugal force more than a prescribed intensity and the instant swing speed upon swing; a magnetic force control device associated with the magnets and for controlling the intensity of magnetic force affecting the magnetic body from the magnets; an announcement mechanism positioned apart with the magnetic body, and for announcing the separation of the magnetic body and the magnets to contact the magnetic body when the magnetic body is separated from the magnets; and whereby a user can easily confirm by the announcement whether a swing more than a prescribed intensity was made to correspond to the intensity of magnetic force controlled by the magnetic force control device.
