Is fixed. Therefore, the relative movement of the instrument panel body and the air conditioning duct can be suppressed until the curing of the adhesive that joins the back surface of the instrument panel body and the joint portion of the air conditioning duct is completed. This eliminates the need for a jig or the like for holding the instrument panel main body and the air conditioning duct, thereby reducing the cost.

  A vehicle instrument panel according to a second aspect is the vehicle instrument panel according to the first aspect, wherein a fitting portion having a fitting groove fitted to the body panel is formed in the duct fixing portion. It has been configured.

  If the fitting part to be fitted to the body panel is formed on the instrument panel body, when the instrument panel body is resin-molded using a mold, the die-cutting direction of the instrument panel body is fitted. It is necessary to match the depth direction of the fitting groove formed in the joint. Therefore, the direction in which the instrument panel body is cut out is restricted, and the degree of freedom of design of the instrument panel body may be reduced.

  On the other hand, according to this instrument panel for vehicles, the fitting part is formed in the duct fixing part formed integrally with the end side part of the instrument panel main body via the integral hinge. Therefore, when the instrument panel body and the duct fixing part are integrally molded with resin using a mold, the duct is fixed so that the mold drawing direction of the instrument panel body matches the depth direction of the fitting groove. What is necessary is just to adjust the rotation angle with respect to the instrument panel main body of a part. Thereby, since the die cutting direction of the instrument panel main body can be set freely, the degree of freedom of the design of the instrument panel main body can be improved.

  A vehicle instrument panel according to a third aspect is the vehicle instrument panel according to the first or second aspect, wherein a pair of ribs protruding downward in the vehicle vertical direction is formed on the end side portion. The duct fixing portion is formed with an insertion portion inserted between the pair of ribs, and one of the rib and the insertion portion is formed with a locking claw protruding to the other side of the rib and the insertion portion. The instrument panel main body is locked to the other of the rib and the insertion portion with the locking claw and restricts relative movement of the insertion portion relative to the pair of ribs in the vehicle vertical direction. When the instrument panel body is bent so that a load acts on the upper and lower sides of the vehicle and the distal ends of the pair of ribs are separated from each other, the locked state with the locking claw is released. Stop There has been a formed configuration.

  According to this instrument panel for a vehicle, when the instrument panel body is bent so that a load acts on the instrument panel body from the upper side in the vehicle vertical direction and the distal ends of the pair of ribs are separated from each other, The locked state between the pawl and the locked portion is released. Thereby, since a duct fixing | fixed part will be in a free state with respect to an instrument panel main body, and the load absorption stroke of an instrument panel main body is ensured, a pedestrian protection performance can be improved.

  As described above in detail, according to the present invention, a jig or the like for holding the instrument panel main body and the air-conditioning duct becomes unnecessary, so that the cost can be reduced.
