PROBLEM TO BE SOLVED: To pressure a tee device for golf practice which has high reliability of ball detection in a technique of automatically detecting the presence of a ball on the tee device for golf practice used in a golf range etc., without a malfunction of ball detection by disturbing factors such as light. SOLUTION: This tee device 1 for golf practicing comprises the cylindrical tee 10 which is disposed upright and has a vertical hole 13 which is opened at its top end 11 and is closed by a lower tee supporting device 12, an air supplying section 20 which supplies air flow from a fan 21 through a pipeline 22 into the vertical hole 13 of the tee, a ball supplying path 30 which places the golf ball B at the top end 11 of the tee, a pressure detector 40 which detects the increase of the air pressure in the air flow supplying pipeline 22 by the placement of the golf ball B on the top end 11 of the tee and a CPU 50 which receives the detection signal of the pressure increase from the pressure detector 40. The supplying of the balls and the lifting of the tee are controlled by the CPU 50.
