An air suction device for a toilet drain passage, which can, independently of the place of installation of a toilet body and conditions of use, constantly generate a siphon effect to perform excellent toilet flushing. The air suction device (20) sucks air from a toilet drain passage (5) connected to the downstream side of a water containing section (4) of a toilet body (1). A first diaphragm (31) is placed in a housing (30H) so as to be movable in the vertical direction in an installed position of the first diaphragm (31). The first diaphragm (31) partitions the housing (30H) into a first chamber (32) on the upper side and a second chamber (33) on the lower side. The second chamber (33) has a suction tank communicating with the toilet drain passage (5). The first diaphragm (31) can be moved upward by an electromagnetic drive device (40). |
