<P>PROBLEM TO BE SOLVED: To provide a sprinkler head in which solder is sufficiently heated by suppressing deformation of a heat-sensitive plate even if the solder spreads laterally by a load always applied to the solder and the force of the solder acts on the heat-sensitive plate. <P>SOLUTION: The sprinkler head 1 includes a heat-sensitive section 51 comprising a plunger 52 having a flange 52a formed thereon, a solder 55 formed on the flange 52a of the plunger 52 and a heat-sensitive plate 53 attached to the upper part of the solder 55 and forming a cylinder. The sprinkler head 1 further includes a cylindrical reinforcing member 80 formed on the outer periphery of a vertical section 53a of the heat-sensitive plate 53 and used to suppress the radial spread of the vertical section 53a of the heat-sensitive plate 53. <P>COPYRIGHT: (C)2013,JPO&INPIT |
