  Then, the operator brings the direction of the shaft 21 b of the fan 21 closer to the rectification direction of the wind direction adjusting member 8. FIG. 7 is a cross-sectional view for explaining a state where the direction of the fan 21 is tilted upward. For example, as shown in FIG. 7, when the rectification direction by the wind direction adjusting member 8 is obliquely upward, the movable portion 22b is rotated about the rotation shaft portion 22a as a central axis (in FIG. And the direction of the fan 21 fixed to the movable portion 22b is tilted upward by an angle α. At this time, the worker tilts the fan 21 with the scale displayed on the side plate 23b2 of the fixing portion 23b as a mark.

  Next, the worker again mounts the bolt 22c1 and the nut 22c2 of the posture holding means 22c while the direction of the fan 21 is inclined upward by the angle α. That is, the operator passes the bolt 22c1 of the posture holding means 22c through the second shaft hole C formed in the movable portion 22b, and is one of the angle adjustment holes A formed in the fixed portion 23b. Then, before the posture holding means 22c is removed, the posture holding means 22c is passed through the angle adjustment hole A positioned above the angle adjustment hole A into which the posture holding means 22c was inserted. Then, the angle adjustment plate 22b2 of the movable portion 22b and the side plate 23b2 of the fixed portion 23b are tightened by the nut 22c2. In this way, the posture holding means 22c maintains the state where the direction of the shaft 21b of the fan 21 is inclined upward by the angle α.

  Next, the operator closes the opened part of the casing 3.

  Finally, the operator attaches the wind direction adjusting member 8 to the casing 3 so that the rectifying direction is upward so as to cover the outlet 3b.

  According to the above embodiment, the fan 21 is attached to the support portion 23 via the angle adjusting mechanism 22 that can adjust the direction of the shaft 21 b of the fan 21.

  Moreover, since the rotating shaft part 22a is provided so that the axial direction may become horizontal, the direction of a shaft can be adjusted to an up-down direction.

  Further, the posture of the movable portion 22b can be easily held by simply passing the bolt 22c1 of the posture holding means 22c through the angle adjusting hole A formed in the fixed portion 23b of the support portion 23.

  Further, the angle adjusting hole A formed in the support portion 23 is a plurality of holes, and the bolts 22c1 of the posture holding means 22c are passed through the respective holes to hold the posture of the fan 21, so that the shaft 21b of the fan 21 It is possible to reliably hold the state in which the axial direction is inclined by a predetermined angle.
