FIRE HYDRANT DEVICE

PROBLEM TO BE SOLVED: To provide a fire hydrant device capable of reducing a work load and capable of suppressing occurrence of damage caused by collision of a fire hydrant door with a front panel by providing a cylinder damper to a turning mechanism part of the fire hydrant door capable of rotatably moving in a forward-folding direction by about 180° to reduce a turning speed of the fire hydrant door.SOLUTION: The lower end of a fire hydrant door 12 is rotatably connected to a lower end edge part of an aperture 11a of a front panel 11 with a hinge 13, and the fire hydrant door 12 can rotatably move between an aperture closing position and an open position by about 180°. On end of a first link 20 is rotatably connected to the rear face of the fire hydrant door 12 around a first pin 22, one end of a second link 23 is rotatably connected to a lower part side of the aperture 11a of the rear face of the front panel 11 around a second pin 27, and the other end of the second link 23 is rotatably connected to the other end side of the first link 20 around a third pin 28. An oil damper 32 is disposed between the other end of the first link 20 and a rear face lower part of the front panel 11.
