PROBLEM TO BE SOLVED: To provide a sprinkler head achieving an excellent appearance by minimizing its exposure from a ceiling surface while maintaining sensitivity of a glass valve. SOLUTION: A cylindrical deflector is arranged to cover the circumference of the upper half of the glass valve. A plurality of openings are formed at regular intervals on the circumference of the deflector. A valve body support section is formed inside of the deflector for receiving and supporting a valve body when the glass valve is broken and the valve body is dropped. A glass valve supporting frame is arranged downward on the bottom of the deflector. With such a configuration, a lower central part of the glass valve supporting frame supports the lower end of the glass valve on the underside of the deflector. COPYRIGHT: (C)2008,JPO&INPIT
