PURPOSE:To comfortably train a golf by switching blow-off of cold air from one spot room cooler and feeding it to a hitting area or a rest area. CONSTITUTION:Chilled air fed into an air flow chamber 1c is alternately blocked at a chilled air blow-off port 12 for training hit and a chilled air floating port 13 for rest by a switching damper 11 which is rotated around a supporting shaft 20 and a pin 21 by the operation of a solenoid 10 to be switched. Then, the damper 11 is rotated, the chilled air flows to an air flow duct 14 for training hot or an air flow duct 16F for rest which is not closed, and the chilled air is discharged to a hitting area A or a rest area B. That is, when a changeover switch is switched to the rest area side, a coil 22 is energized, a plunger 23 is attracted to the coil 22, and reciprocated at a predetermined stroke. It is transmitted to the damper 11 by a shaft 25 to be rotated at the shaft 20 and the pin 21 as a center to block the port 12 and to discharge the chilled air to the area B. |
