<P>PROBLEM TO BE SOLVED: To provide a sprinkler head in which the exposed portion into a room at a non-actuation time is made few as far as possible, thereby the indoor fine sight is not damaged, and the outer diameter is small. <P>SOLUTION: The sprinkler head includes: a first rod L1 movably supporting a deflector 4; a relay ring 12A supporting the first rod L1; a second rod L2 movably supporting the relay ring 12A; and a lock ring 12B supporting the second rod L2. The rods L1 and L2 are arranged in parallel shifting the axes thereof. When a heat sensitive operation part 5 performs resolution/falling at the time of extinction actuation, the lock ring 12B moves the inside of a frame 2 downward to lock with a lock flange 11, and supports the relay ring 12A to be hung on the external of the frame 2 through the second rod L2. The relay ring 12A supports the deflector 4 to be hung further downward through the first rod L1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
