Abstract

PURPOSE: To reduce overall height of a sprinkler head by securing thermo- sensitive plates fast to the bottom edge of a rod, and embodying the sprinkler head in a link mechanism. CONSTITUTION: A link mechanism constituting a thermo-sensitive disassembling part is configured so that a disc-shaped link piston 13 is formed in a single piece over a rod 11, where a link holding plate 14 to support the shoulders 12b of a pair of arms 12 is screwed fast. When the leg part 12c of an arm 12 is disengaged from an arm supporting plate 17, the link mechanism is disassembled and falls down. At this time, a pinching plate 15 and the arm supporting plate 17 slide the rod 11 and move upward, while thermo-sensitive plates 18 and 19 secured to the rod 11 remain out of moving upward. This liberates necessity for installing a spacer otherwise required to generate arm movement between the arm supporting plate and thermo-sensitive plates 18 and 19, which enables suppressing the overall height of sprinkler head, and there is no risk of impairing fine appearance.
