PROBLEM TO BE SOLVED: To prevent the increase in the size of an electric drive assembly constituting the tee device and to enable a golfer to tee up balls at all times even in long use. SOLUTION: The electric drive assembly constituting the tee device is formed by installing a tee adjuster which stops a tee height adjusting motor m1 constituting the same at a desired height position of the tee and a tee lifting device to be located to the uppermost position and the lowermost position with the revolution of a tee lifting motor m2 by the actuation of optical sensors in superposition in a vertical direction. The taking out of the driving power by the two motors described above is executed by a transmission member (j) from the bottom end of a grooved lever g via this lever engaging with respective guide rollers 5 and 6 arranged at the eccentric positions of the adjusting disk n1 and lifting disk n2 of the respective motors from these rollers. The lifting tee of the tee lifting device operated by this transmission member is constituted by elastically disposing a spring between the same and a protector (v) inserted onto the same.
