<p>One differential-pressure detecting conduit (71) and the other differential-pressure detecting conduit (72) are so formed as are juxtaposed at a predetermined spacing in the longitudinal direction. Moreover, the one differential-pressure detecting conduit (71) continues upstream of a continuing center position (70) between a second inflow passage (67) and a first inflow passage (43). Still moreover, the other differential-pressure detecting conduit (72) continues downstream of a continuing center position (69) between a second outflow passage (66) and a first outflow passage (44).</p> |
