PURPOSE:To surely detect air leakage of a tire or puncture by connecting one end of an air supplying pipe which comprises a flow rate detector and a solenoid valve etc. to respective tires of a vehicle, and providing an air tank which comprises a pressure switch in the other end. CONSTITUTION:When causing air leakage in any one of horizontal tires 4 of a captioned monorail vehicle, pressure air in an air tank 16 is supplied to leaked horizontal tires 4 through a solenoid valve 21 and a flow rate detector 20 until the pressure difference will become zero. When the pressure difference has become zero, the air supplying is stopped, and a display lamp for alarming is turned off by a flow rate detector 20. On the other hand, when any one of the horizontal tires 4 is punctured, the pressure air is simultaneously supplied to the horizontal tires 4. When the air pressure in the air tank 16 lowers below given value, a pressure switch 15 is turned on to burn the display lamp for alarming and the solenoid valve 21 is turned on to close the connecting pipe 18 of the air tank 16. |
