Abstract: The present invention provides a durable golf tee capable of conserving as much as possible the impact energy transmitted to the golf tee and preventing possible flight thereof from the ground. The golf tee comprises a stick pin, the lower end of which is formed in a tapered shape, to stick into the ground, a ball-holding member placed on the top of the stick pin and provided with a small hole at the bottom of a hollow part, and a flexible connecting member, the lower end of which is fixed on the stick pin. The connecting member is provided with a flange on the upper end for binding slidably the ball-holding member to the stick pin and inserted into a hollow part H through a small hole perforated at the bottom of the ball-holding member. Notches 4b1 are formed between the flange of the connecting member and the ball-holding member to let air escape upward.
