Document Type and Number:
Japanese Patent JP7077438
Kind Code:
B2
Abstract:
To make it easy to take out a nozzle without depending on a position to operate even when the nozzle is freely removably engaged with a reverse surface of an upper door.SOLUTION: A housing is buried and installed in an observer passage along a tunnel wall face and stores a hose 76 with a foam nozzle 78 inside. An upper door is composed of a first upper door 34 and a second upper door 36. The first upper door 34 is freely openably/closably pivotally supported vertically together with the second upper door 36 with a front edge part as an axis at an upper surface door opening of the housing on a road side of the observer passage, and the second upper door 36 is freely openably/closably pivotally supported vertically with a rear edge part as an axis at a second upper surface door opening of the first upper door 34. A nozzle holder 86C is freely removably engaged with the foam nozzle 78, and is fitted to a reverse surface of the second upper door 36 so that an exposure position of the foam nozzle 78 when the first upper door 34 is opened together with the second upper door 36 with the front edge part as an axis becomes higher than when the second upper door 36 is opened with the rear edge part as an axis.SELECTED DRAWING: Figure 14
