Abstract: A vehicular air conditioning device includes an air conditioning case having first, second case introduction ports and first, second case discharge ports, and a fan. The first, second case discharge ports are offset upward and downward in an up-down direction relative to a rotation axis, respectively. A first inner guide surface of an inner guide plate is located on the one side of a second inner guide surface in the left-right direction. Air introduced through the first case introduction port is guided by the first inner guide surface to be drawn from a first passage into the fan, the air being blown upward to flow through the first case discharge port. Air introduced through the second case introduction port is guided by the second inner guide surface to be drawn from a second passage into the fan, the air being blown upward to flow through the second case discharge port.

Abstract: A blower includes a centrifugal fan and a partition wall disposed in a suction space in the centrifugal fan. The partition wall has a base portion extending along a fan central axis to partition the suction space into a first space for a first fluid and a second space for a second fluid. The partition wall has an enlarged portion connected to an end of the base portion on another side of the fan central axis. The enlarged portion covers a part of a fan boss. A clearance passage is defined between the enlarged portion and the fan boss and has a first space side opening and a second space side opening. The enlarged portion is biased in the suction space to the second space such that a pressure at the second space side opening is less than a pressure at the first space side opening.
