FIG. 8 is a plan view showing an example, and FIG.

In the drawing, reference numeral 1 denotes a fire hydrant box, in which a base end is connected to a fire hydrant valve 2 communicating with a fire hydrant pump, and a nozzle 3 such as a water discharge nozzle or a spray nozzle is provided at the tip. With the fire-fighting hose 4 attached to the fire hydrant box 1,
It is wound around a hose hook 5 fixed to the back plate 1a of the fire hydrant box 1 and housed, and the tip of the wound shape retaining hose 4 wound and housed is wound back into the opening 1b of the fire hydrant box 1. A door 6 is provided which is opened and closed by a hinged portion 6b provided in an azimuth direction. In addition, a rear surface 6a of the door 6 is opposed to a position where the nozzle 3 of the shape retaining hose 4 fits along a winding circle in a closed state. A support 7 for supporting the nozzle 3 is provided at the site.

The support 7 comprises a rotating member 8 and a universal piece 9
The turning member 8 is rotatably mounted on the door 6 with a horizontal shaft 10 made of a screw, and the turning member 8 is provided with a vertical shaft 11 to turn the universal piece member 9. A stopper that is attached to the end of the universal piece member 9 so as to be able to hold the nozzle 3 at the tip of the universal piece member 9 and that suppresses the rotation angle of the universal piece member 9 to approximately 90 ° with respect to the back surface 6a of the door 6. 8 a is provided on the rotating member 8.

FIGS. 7 and 8 show another example of the support member 7. The support member 7 'shown in FIG. 7 is formed by twisting the base of the universal piece member 9' by 90.degree. A stopper 8a 'rotatably mounted on the shaft 11' and abutting on the rotating member 8 '.
