BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle duct fixing structure for guiding air to an air outlet for blowing air into a vehicle compartment.

[0002]

2. Description of the Related Art Conventionally, a vehicle such as an automobile is equipped with an air conditioner (air conditioner), and air such as warm air or cold air conditioned by this air conditioner is delivered to an air outlet by an air conditioning duct. It is designed to be blown out into the passenger compartment from the air outlet.

Further, the duct is fixed to the inner surface of the interior material so as not to be exposed in the passenger compartment, and a duct fixing device for fixing the duct to the inner surface of the interior material is described in, for example, Japanese Patent Application Laid-Open No. 7-179117. Those that have been made are known.

The duct fixing device disclosed in the above publication is provided with a projecting piece having a semicircular cross section at a predetermined position of the duct so as to project to the outer peripheral side. Since it is inserted while elastically deforming between the contact parts, and the mounting piece protruding on the opposite side of the protruding piece is fixed to the front cluster housing with a screw, it is sufficient to simply insert the protruding piece. The workability is greatly improved.

However, in the duct fixing device disclosed in the above publication,
The structure in which the projecting piece of the duct is sandwiched between the two members, the front cluster housing and the rear cluster housing, makes it necessary to divide the interior material into two when fixing the duct inside the interior material such as the center pillar for interior of the vehicle interior. Therefore, there is a problem that the number of parts increases and the cost increases.

On the other hand, when fixing a duct to the inner surface of an interior material such as a center pillar, conventionally, a plurality of clip seats are provided on the inner surface of the interior material having a substantially U-shaped cross section,
The clip seat is utilized to fix the duct to the inner surface of the interior material, and the clip attached to the tip of the clip seat is press-fitted into the attachment hole of the vehicle body panel to attach the interior material to the vehicle body panel.

In the above conventional duct mounting structure, a clip seat is provided so as to project on the inner surface of the connecting portion between the flat plate portion and the side plate portion of the interior material having a substantially U-shaped cross section.
The duct is fixed to this clip seat.

However, since the interior material such as the center pillar is elastically sandwiched and fixed between the open edge of the side plate portion and the vehicle body panel, the welt for preventing the intrusion of rainwater and the like is fixed. The part side is elastic and has low rigidity.

Therefore, in the conventional duct fixing structure in which the duct is fixed to the clip seat protruding near the side plate portion having low rigidity, the duct cannot be surely fixed, and in order to securely fix the duct, the duct is fixed. Since it is necessary to provide a large number of fixing means for fixing the inner member, there are problems that the mold for molding the interior material becomes complicated, the mold cost becomes high, and it takes time to assemble the duct.

The present invention has been made to solve the above-mentioned conventional problems, and provides a vehicle duct fixing structure in which the duct is fixed by a duct locking means provided in a highly rigid portion of the interior material. The purpose of the present invention is to provide a duct that can be reliably fixed to the inner surface of the interior material.

Can be fixed to
Since the rigidity of the flat plate portion is improved by the duct locking means, it is possible to prevent the interior material from bending.

In order to achieve the above object, the vehicle duct fixing structure according to the present invention has a pedestal provided with a duct locking means projecting from an inner surface of a flat plate portion of an interior material, and a duct assembly formed at a tip portion of the pedestal. The duct is fixed to the interior material by locking an elastic fixing piece formed of a stop portion and protruding from the duct to the duct locking portion.

With the above structure, the duct can be easily fixed to the interior material in a short time, so that the number of assembling steps can be reduced.

In order to achieve the above object, the fixing structure for a vehicle duct according to the present invention is such that the duct locking means serves as a clip seat by attaching a clip for attaching the interior material to the vehicle body panel at the tip of the pedestal of the duct locking means. It is also used.

With the above construction, since the number of clip seats protruding from the interior material can be reduced, the die for molding the interior material can be simplified and the die cost can be reduced.

In order to achieve the above object, the fixing structure for a vehicle duct according to the present invention is such that a plurality of bosses are provided on the inner surface of the interior material so as to be spaced apart in the longitudinal direction of the interior material, and the boss is fitted to the duct side. A positioning hole is provided.

With the above construction, when the positioning hole of the duct is fitted in one of the bosses, by rotating the duct around this boss, another positioning hole can be fitted in the other boss. Since the positioning of the boss and the positioning hole becomes easy, the fixing piece of the duct and the duct locking portion are positioned by fitting the positioning hole to each boss,
The fixed piece can be easily locked to the duct locking portion.
