Further, when the wind direction deflecting device 12 is attached to the air passage component body 8 together with the air passage tip component 9, the vertical wall 8a of the air passage component body 8 is provided with a mounting plate attachment claw shaping hole 8c. Since a mounting claw shaping hole closing member 15 for closing the mounting plate mounting claw shaping hole 8c is projected at the tip of the panel locking member 22 of the road leading edge component 9, the vertical wall of the air passage component main body 8 is projected. The mounting claw shaping hole closing member 15 protruding from the front end of the panel locking member 22 of the air passage tip component 9 is inserted into the mounting plate mounting claw shaping hole 8c of 8a, and the installation plate attachment of the air passage component main body 8 is performed. By closing the claw shaping hole 8c, the flow of air to the back side of the air path component main body 8 can be stopped, and the dew condensation on the back surface of the air path component main body 8 can be prevented.
If the attachment claw shaping hole closing member 15 is not provided in the air passage tip component 9, the installation plate attachment claw formation hole 8c of the air passage component main body 8 must be further closed by another component.

  As described above, according to the first embodiment, the air path 6 in which the air heat-exchanged by the heat exchanger 4 is sent out from the blower outlet 7 by the blower 5 is used as the air from the blower 5. Formed by an air passage component main body 8 that guides to the front of the air outlet and an air passage tip component 9 that can be attached to the air passage component main body 8 and guides the air guided by the air passage component main body 8 to the air outlet 7. Then, a wind direction deflecting device 12 in which a left and right wind direction plate 10 that changes air flow left and right, an up and down air direction plate 11 that changes air flow up and down, and an air path tip component 9 are integrally attached to the air outlet 7. As a result, the movable diffuser is eliminated and a separate member for moving the movable diffuser becomes unnecessary, the mounting structure is simplified, and material costs and processing costs can be suppressed.

  In addition, the air passage 6 that guides air from the blower 5 to the air outlet 7 can be attached to the air passage component main body 8 that guides the air from the air blower 5 to the front of the air outlet 7, and the air passage component main body 8. Since the air guided to the air outlet part body 8 is formed by the air path tip part 9 that guides the air to the air outlet 7, the front end of the air path part body 8 is shortened to the rear side. When the wind direction deflecting device 12 having the air path is attached to the air path component body 8 together with the air path tip component 9, the right and left wind direction plates 10 are prevented from interfering with the air path tip of the air path component body 8 and the wind direction deflecting device 12 is provided. Therefore, the left and right wind direction plates 10 can be enlarged, and the amount of air blown by the left and right wind direction plates 10 can be increased.
