クラー装置。 A cylindrical device body 1 vertically connected to the water supply port side of a water distribution pipe, a frame-shaped sprinkler head 9 attached to the lower part of the device body 1, and a device body 1 connected to the water distribution pipe. A main rod 15 is vertically installed in the porridge body 1 on the side of the upper opening 14 to close the upper opening 14 of the sprinkler through the valve cap 13, and there is mutual contact between the lower surface of the main rod 15 and the upper surface of the sprinkler head 9. It consists of a plurality of sub-rods 17a, which are shorter than the length of the sprinkler head 9 and are interposed vertically in combination while being in contact with the sprinkler head 9, and the sub-rods 17a are
, ... and a plurality of sub-rods 17a, ... interposed between the main rod 15 and the sprinkler head 9 in a dry sprinkler system configured such that the main rod 15 falls and the upper opening 14 of the device body 1 is opened. A dry sprinkler device characterized in that the outer peripheral surface of at least the uppermost sub-rod 17a is tapered.
