<p>A sucking mechanism and a sucking device. The sucking device capable of sucking a sucked object by a large suction force only when the sucked object is present without being arrested by the positioning order of a suction pump and the sucked object, comprising a suction port (110) sucking the sucked object (3) and a connection hole (120) to which a branch tube (21) branched from the suction pump (2) is connected and which sucks a gas in an indoor space (15). The device also comprises a flow passage switching mechanism (1a) which, when the sucked object (3) is not present at the suction port (110), sucks the minute amount of gas through a first flow passage (4) with a slight clearance between a through hole (134) and a guide member (112) reduced by covering a connection hole (120) by a shield member (13) and, when the sucked object (3) is present at the suction port (110), releases the shield member (13) from the connection hole (120) and sucks the gas through a second flow passage (5) larger in the minimum flow passage width than the first flow passage (4).</p> |
