Claim 2:
3. A golf tee comprising:
a support inserted into the ground; and
a rotary portion rotatably coupled to the support and having an upper surface on which a golf ball rests,
wherein the support comprises a pointed insertion portion formed at a lower portion thereof and inserted into the ground, a hollow receiving portion formed at an upper portion thereof and protruding above the ground, the receiving portion having an insertion hole open at one side thereof, and a stepped portion protruding outside an upper surface of the receiving portion;
the rotary portion comprises a head formed at one side thereof and allowing a golf ball to rest thereon and a coupling portion formed at the other side thereof and coupled to the support;
the coupling portion of the rotary portion is inserted into and coupled to the receiving portion of the support; and
the coupling portion has a protrusion formed at a portion of an outer circumferential surface thereof and the receiving portion has a receiving groove receiving the protrusion therein such that the support and the rotary portion are vertically aligned with each other with the protrusion received in the receiving groove,
wherein the support further comprises:
multiple cutouts formed in the receiving portion to allow the receiving portion to be elastically deformable such that the coupling portion of the rotary portion is coupled to or separated from the receiving portion; and
