<p><P>PROBLEM TO BE SOLVED: To propose an alarm having a guide wall installed therein through which fluid from the outside of a housing can flow efficiently to a detection unit in the housing. <P>SOLUTION: As a vertical crosspiece section 113 is installed at an opening 111 through which fluid flows from the outside, a plurality of guide walls 51 are extended from the vertical crosspiece part 113 toward a detection unit 3 installed in a body part 11. Thus, the vertical crosspiece section 113 functions as a part of the guide walls 51, and fluid flowing from the opening 111 to the inside of the housing 1 at the outer circumferential side of the detection unit 3 is guided through a guide path 52 configured between the guide walls 51 to the detection unit 3. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
