Training machine for golf swing

A training machine for golf swing including a club shaft having a grip at a top end thereof, and a club head engaged with a lower end of the club shaft, comprising:

• a plurality of magnets provided in an opposite position relative to a grip end of a shaft;
• a collision means attachable to the magnets, and adapted to be separated from the magnets and collided with other objects by a centrifugal force of more than a prescribed amount and an instant swing speed upon swinging the shaft;
• a magnetic force control means associated with the magnets and for controlling the intensity of magnetic force affecting the collision means from the magnets;
• and
• an announcement means positioned apart from the collision means, and for announcing the separation of the collision means and the magnets to contact the collision means when the collision means is separated from the magnets,
• whereby a user easily confirms by the announcement means whether a swing more than the prescribed intensity was made to correspond to the intensity of magnetic force controlled by the magnetic force control means.
