摘要:To hinder a phase difference around a fan axis, which is caused in mutualarrangement of a plurality of air flows due to rotation of a blowing fan between aplurality of upstream-side ventilation paths and a plurality of downstream-side

ventilation paths.SOLUTION: An upstream-side guide member 26 has a shape in which,with respect to one side of the upstream-side guide member 26 in a fan-axis directionDRa, the other side thereof is twisted around a fan axis in a reverse direction to a fanrotating direction RTf. The upstream-side guide member 26 causes air to flow along thetwisted shape, thereby guiding the air to a blowing fan 201. Consequently, an air flowfrom each of first and second upstream-side ventilation paths is caused to move in thereverse direction to the fan rotating direction RTf in advance and then move into theblowing fan. This acts in a direction in which a phase difference around the fan axis, causedby rotation of the blower fan, is nullified in mutual arrangement of a plurality of air flowsmoving from the first and second upstream-side ventilation paths to first and seconddownstream-side ventilation paths. Accordingly, the phase difference can behindered.SELECTED DRAWING: Figure 2
