And a ball receiving member having a ball receiving portion formed at one end and having an axial hole that engages with the supporting shaft portion of the tee body, the supporting shaft of the tee body. A male screw is formed on the outer surface of the part, and a female screw is formed in the axial hole of the ball receiving member to engage with the male screw of the support shaft part of the tee body. Accordingly, the tee body can be held at different positions in an axial direction with respect to the support shaft portion of the tee body.

However, the golf tee disclosed in the above-mentioned Patent Document 1 has a problem that the structure for adjusting the height of the tee is complicated, the manufacturing process is large, and the cost is increased. Also, when hitting a ball, there is a concern that the tee body may be blown off from the leg depending on the hit of the club head. In that case, the tee body must be searched and reattached to the leg portion, so that It could be a loss of time.

As a tee that can solve such a problem, the present applicant has previously proposed a golf tee that does not break or lose a tee during a tee shot (Patent Document 2).

The golf tee described in the above-mentioned Patent Document 2 is a golf tee including an insertion portion that is inserted into the ground and a placement portion on which a golf ball is placed. The insertion portion is a hard member, and the placement portion is flexible. The insertion portion is preferably made of a hard resin, and the mounting portion is preferably made of a soft resin having flexibility.
