That is, the auxiliary reinforcing portions 62a, 62b are connected at one end to the vicinity of the central portion in the vertical direction of the both side plate portions 65a, 65b, and at the other end, lower inner wall portions 36a of the inner wall portions 27a, 27b of the upper nozzle portions 21a, 21b, The upper end portion of 36b is connected to a continuous position (corner portion) between the lower inner wall portions 36a and 36b and the upper inner wall portions 37a and 37b. Therefore, the reinforcing portion 17 is separated from the connecting portion 16 by the connecting portion main body 51 and the auxiliary reinforcing portion 62a, the upper plate portion 66, and the auxiliary reinforcing portion 62b that are spaced upward with respect to the connecting portion main body 51. The other nozzle portions 15a and 15b are connected. The auxiliary reinforcing portions 62a and 62b are substantially parallel to the upper plate portion 66. That is, the auxiliary reinforcing portions 62a and 62b are substantially horizontal when the defroster nozzle 10 is attached to the instrument panel 12. Further, the front end portions of the auxiliary reinforcing portions 62a and 62b are connected to the connecting reinforcing portion 52 at a continuous position (corner portion) between the connecting portion main body 51 and the connecting reinforcing portion 52 or at a position near the continuous position. Therefore, the auxiliary reinforcing portions 62a and 62b are formed so as to be gradually separated from the front portion to the rear portion with respect to the connecting portion main body 51.

  The defroster nozzle 10 is connected and fixed to the air conditioning device or the lower nozzle communicating with the air conditioning device at the mounting bracket portions 31a and 31b, and fixed inside the instrument panel 12 at the mounting portions 42a and 42b. Side nozzle portions 22a and 22b are each connected to a side defroster. In this mounted state, the defroster nozzle 10 is positioned at a substantially central portion in the vehicle width direction of the instrument panel 12, and the first outflow openings 29 a and 29 b exposed at the upper portion of the instrument panel 12 face upward, and the windshield 13 It faces the surface of the passenger compartment 11 side. At this time, the reinforcing part 17 is provided along the both sides in the connecting part 16 that connects the one and the other nozzle parts 15a, 15b, so that the load F1 that breaks in the both sides (width direction) (FIG. 4). (The required minimum rigidity is ensured), and even when fixed to the instrument panel 12 with the mounting portions 42a and 42b on both sides, the first side with respect to the windshield 13 is not bent. The blowout angle of the conditioned air from the outlet openings 29a and 29b can be set with high accuracy. Then, the conditioned air from the air conditioner that has flowed into the upper nozzle portions 21a, 21b and the side nozzle portions 22a, 22b from the first and second inflow openings 28a, 28b, 47a, 47b passes through the upper nozzle portions 21a, 21b. While being diffused in the vehicle width direction, it is sprayed from the slit-like first outflow openings 29a, 29b to the windshield 13, and is supplied to the side defroster at the side nozzle portions 22a, 22b, from the side defroster to the door glass. Sprayed to eliminate fogging of windshield 13 and door glass caused by water vapor.

  Further, for example, when the collision load F2 when the colliding body collides with the windshield 13 is input from above (at the time of impact input), the defroster nozzle 10 has the mounting portions 42a and 42b on both sides of the instrument panel 12. Since the center portion (opening portion 18) is not fixed to the instrument panel 12, the position of the opening portion 18 easily moves downward, and when this movement proceeds, the collision load F2 Stress concentrates on the connecting part between the auxiliary reinforcing parts 62a, 62b along the intersecting (orthogonal) direction and both side plate parts 65a, 65b of the main reinforcing part 61, and it is easy to form a trapezoid with a low load starting from these connecting parts. (FIG. 4). As a result, the deformation amount (displacement amount) of the windshield 13 is ensured, the impact is effectively absorbed, the reaction force against the collision body is relaxed, and the collision body protection performance is improved.

  As described above, according to the present embodiment, it is possible to provide the defroster nozzle 10 that can be easily deformed at the time of impact input to alleviate the impact while ensuring the rigidity and accuracy of the single unit.

  In particular, the reinforcing portion 17 has a simple structure by providing the connecting portion 16 with the main reinforcing portion 61 with a predetermined width L along both sides and providing the auxiliary reinforcing portions 62a and 62b on both sides of the main reinforcing portion 61. As a result, the connecting part 16 can be reinforced more reliably, and the rigidity and accuracy of the unit can be secured more easily, and stress is concentrated on the connecting part between the main reinforcing part 61 and the auxiliary reinforcing parts 62a and 62b when an external impact is input. As a result, the first and other nozzle portions 15a and 15b are more easily deformed, and the impact can be more reliably mitigated.

  Further, the main reinforcing part 61 is formed in a box shape, and one and other nozzles facing both sides (both side plate parts 65a and 65b) of the main reinforcing part 61 and both sides of the main reinforcing part 61 by the auxiliary reinforcing parts 62a and 62b. By connecting the portions 15a and 15b (inner wall portions 27a and 27b (lower inner wall portions 36a and 36b)), one and other nozzle portions 15a and 15b are connected by the connecting portion 16 (connecting portion main body 51) and the reinforcing portion 17. Since the two upper and lower positions are connected, the rigidity with respect to the load that is bent in both directions and the rigidity in the front-rear direction can be further improved, and the sub-reinforcement portions 62a and 62b are formed in a plate shape along both directions. And the sub-reinforcement portions 62a and 62b are easily weakened against an external impact, and can be more easily deformed when an external impact is input.

  The reinforcing portion 17 has a relatively simple shape including a box-like main reinforcing portion 61 and plate-like sub-reinforcing portions 62a and 62b, so that it is not affected by the layout of the vehicle or the structure of the mold. The reinforcing portion 17 can be easily set.

  Moreover, since the main reinforcing portion 61 and the auxiliary reinforcing portions 62a and 62b of the reinforcing portion 17 are formed along the front-rear direction, which is the mold opening direction of the mold of the defroster nozzle 10, respectively, It is not necessary to provide a slide core or the like, and can be manufactured at low cost.

  The present invention can be suitably used, for example, as a defroster nozzle that blows conditioned air on a front windshield.
