  Moreover, 2nd invention can be set as the structure which the said 1st air derivation | leading-out part has an inclined wall (49, 50) which deflects the direction of the flow of the said air.

  According to a third aspect of the present invention, the first outlet has a flat fixed fin (41), and the second outlet defines the air flow path and is disposed substantially parallel to the fixed fin. It can be set as the structure which has a pair of wall (56a, 56b).

  According to the first aspect, by integrally forming the first outlet and the second outlet arranged in the vicinity of each other, the number of parts can be reduced and the manufacture of the outlet is facilitated. Further, the direction of the air blown out from the first outlet (for example, the side of the vehicle) is made to coincide with the direction of the air blown out from the second outlet (for example, the rear of the vehicle) while matching the die-cutting directions of the first outlet and the second outlet. Can be set in different orientations. Therefore, the degree of freedom in design can be increased without complicating the structure of the mold for molding the first and second outlets. In addition, according to the second invention, it is possible to form the air flow path of the first outlet in a different direction from the air flow path of the second outlet with a simple configuration. Further, according to the third invention, it is possible to guide the air discharged from the first outlet in a desired direction by the fixed fin while matching the die-cutting directions of the first outlet and the second outlet.

Function. As shown also in FIG. 2, a fixed lateral fin 41 is provided in the rear (vehicle compartment side) outlet opening 14a exposed from the instrument panel 2 so as to divide it into two vertically. Further, the front end of the air outlet 13 of the first duct 11 is inserted into the introduction opening 14 b in front of the first outlet 14.

  The air flow path of the first outlet 14 is defined by inner surfaces of an upper wall 45a, a lower wall 45b, a left wall 45c, and a right wall 45d that are substantially flat. The inner surface of the upper wall 45a has a rear side (blowing side) inclined upward as shown by line A in FIG. 4 with respect to the horizontal direction shown by line H, and the horizontal fin 41 has substantially the same inclination. (That is, substantially parallel to the inner surface of the upper wall 45a). As for the inner surface of the lower wall 45b, the front side is inclined slightly upward from the upper wall 45a, whereby the air flow path of the first outlet 14 is formed to be slightly tapered toward the rear. The inner surfaces of the left wall 45c and the right wall 45d are formed so as to be substantially parallel to each other. Note that the air blown from the blowout opening portion 14 a of the first outlet 14 is directed obliquely upward along the upper wall 45 a, the lower wall 45 b, and the lateral fins 41 that are inclined upward.

  Here, as shown in FIG. 3, the air flow path of the air outlet 13 of the first duct 11 is defined by the inner surfaces of the upper wall 46a, the lower wall 46b, the left wall 46c, and the right wall 46d. As shown in FIG. 5, the left wall 46 c and the right wall 46 d of the air outlet portion 13 of the first duct 11 have straight portions 47 and 48 that extend substantially forward and rearward and upper portions 47 and 48, respectively. And inclined portions (inclined walls) 49 and 50 that are inclined to the right and are connected to the first outlet 14. In this case, the center in the left-right direction of the air flow path defined by the straight portions 47 and 48 is offset to the left side (vehicle interior side) with respect to the center in the left-right direction of the air flow path in the first outlet 14. Is in a state. Thereby, as shown by the arrow in FIG. 5, the air introduce | transduced from the introduction opening part 14b of the 1st outlet 14 is guide | induced to the right (direction of a side window) along the inclination parts 49 and 50, and the As a result, air is blown out to the right rear from the blowing opening 14a of the first outlet 14.

  The second outlet 16 is made of a synthetic resin cylindrical member having a substantially rectangular cross section, and functions as a blowing device that blows air toward the rear of the vehicle compartment. As shown also in FIG. 2, a synthetic resin fin assembly 54 in which a plurality of movable horizontal fins 51 and vertical fins 52 are attached to a frame 53 in the rear blowing opening 16 a exposed from the instrument panel 2.
