ている。2. Description of the Related Art FIGS. 5 and 6 show the structure of a rear waist portion of a conventional automobile. In the figure, reference numeral 1 is a rear parcel panel, and a rear waist panel 2 having a substantially L-shaped cross section is joined to a lower surface of a rear end portion thereof. A closed cross section 3 is formed. A ventilation port 4 is formed which penetrates the upper wall and the lower wall of the closed cross-section portion 3 and connects the vehicle compartment R and the trunk room T to each other. The upper edge of the rear portion of the closed cross section 3 is a rear window panel mounting surface 5 that is inclined and formed in a forward tilted state, and the lower edge of the rear window panel 6 is bonded and fixed to the rear window panel mounting surface 5. Then, the drip channel 7 is formed. The trim 8 arranged on the rear parcel panel 1 is divided into a main trim 8a and a rear trim 8b, and a rear end portion of the main trim 8a is disposed above the rear trim 8b so as to communicate with the ventilation port 4. The inside air introducing portion 9 is formed. This similar structure is shown, for example, in Japanese Utility Model Publication No. 61-122108.

両立が行われない。Problems to be Solved by the Invention In order to secure ventilation capacity, it is necessary to raise the position where the main trim 8a is arranged and set the gap δ of the inside air introducing portion 9 to be relatively large, and the rigidity of the rear waist portion. In order to increase the height of the closed cross section 3, it is necessary to increase the height dimension h of the closed cross section 3 to secure a sufficient closed cross section, and the height dimension H from the bottom wall of the closed cross section 3 to the trim 8 is compared. It becomes big. Therefore, it becomes difficult to secure the rear view and the trunk capacity. That is, when the height of the rear waist portion having the height H is increased to increase the trunk capacity,
As a result, the rear view is narrowed, and conversely, if the ground clearance of the rear waist portion is lowered and an attempt is made to expand the rear view, the trunk capacity is narrowed and the rear view and the trunk capacity are not secured at the same time.
そこで、本発明はリヤウエスト部の剛性および換気性
能を損なわずに、後方視界の確保とトランク容積の確保
の両立を図ることができる自動車のリヤウエスト部構造
を提供するものである。Therefore, the present invention provides a rear waist portion structure of an automobile capable of ensuring both rear visibility and trunk volume without impairing the rigidity and ventilation performance of the rear waist portion.

に、前記換気口に連絡する内気導入部を形成してある。Means for Solving the Problems A rear waist panel is joined to a rear end portion of a rear parcel panel to form a closed cross section, and a ventilation port that penetrates the closed cross section and connects a vehicle compartment and a trunk room is formed. In the above structure, a vertical wall portion is formed on the upper wall of the closed cross-section portion so as to separate the closed cross-section portion into front and rear portions, and a ventilation port is formed in the front closed cross-section portion. Between the rear end portion of the trim disposed in and the recessed portion of the vertical wall portion, an inside air introduction portion communicating with the ventilation port is formed.

ことなく可及的に小さくすることができる。Since two closed cross sections before and after operation are formed, the total closed cross section area can be sufficiently secured even if the height dimension of each closed cross section is narrowed, and the trim installation position is not increased. Also, since the inside air introducing portion with a sufficient gap is formed between the end portion after the trim and the recessed portion of the vertical wall portion, the height dimension from the loss wall of the closed cross section portion to the trim is reduced in rigidity and ventilation. It can be made as small as possible without degrading the performance.

を形成してある。In FIGS. 1 to 4, 11 is a rear parcel panel formed in a flat plate shape, and a rear waist panel 12 having a substantially hat-shaped cross section is joined to the upper surface of the rear end portion. A vertical wall portion 13 having a substantially V-shaped cross-section extending to the vicinity of both left and right ends is provided in a substantially central portion of the upper surface of the rear waist panel 12, and the rear window panel 23 is joined to the upper edge of the rear portion. A front window mounting surface 14 which is inclined forward, and a drip channel portion 15 following the rear window panel mounting surface 14 are formed.
17, the lower surface of the vertical wall portion 13 and the drip channel portion 15 are respectively joined to the upper surface of the rear end portion of the rear parcel panel 11 to form two front and rear closed cross-section portions 18 and 19 separated by the vertical wall portion 13.

示す。In the present embodiment, the closed cross section of the rear parcel panel 11
Recesses 11a, 11a that slightly bulge toward the trunk room T side are formed at positions corresponding to 18, 19 to secure the area of the closed cross-sections 18, 19 and ensure the surface rigidity of the rear parcel panel 11 itself. I am trying to Also, at both ends of the rear parcel panel 11,
The rear waist panel 12 and the parcel side panel 24 that is spot-joined are arranged.
Is connected to the rear pillar inner 27 through the parcel side panel 24. The parcel side panel 24 is formed with a recessed portion 24a which forms a closed cross-section portion 25 communicating with the closed cross-section portions 18 and 19 with the rear waist panel 12.
Since the recessed portion 24a is located just above the rear wheel house 26 and does not affect the effective volume of the luggage compartment T, the recessed portion 24a is gradually deep-drawn to increase the area of the closed cross section 25. The rigidity of the joint between the rear parcel panel 11 and the rear pillar inner 27 can be increased. In FIG. 3, 28 is a trunk floor and 29 is a rear fender.

Since the rear two closed cross-sections 18 and 19 are formed, each closed cross-section 1
Even if the height dimensions of 8, 19 are narrowed as indicated by h 1 and h 2 , the total closed cross-sectional area can be sufficiently secured, so that the rigidity of the rear waist portion is not impaired. Also, the main trim 21
Even if the installation position of a is not raised, the inside air introduction part 22
Since the gap δ can be secured, the ventilation performance is not impaired. As described above, the height dimension of the closed cross-sections 18 and 19 is narrowed and the height of the main trim 21a is lowered, so that the height from the bottom of the closed cross-sections 18 and 19 to the main trim 21a is reduced to H. Since it can be narrowed as indicated by 1 , it is possible to achieve both the expansion of the rear field of view and the expansion of the trunk capacity.

の両立を図ることができる利点がある。EFFECTS OF THE INVENTION As described above, according to the present invention, since the vertical wall portion recessed in the upper wall of the closed cross-section portion separates the front and rear closed cross-section portions, the height of each closed cross-section portion is increased. It is possible to secure a sufficient total closed cross-sectional area even if the dimensions are reduced, and even if the trim installation position is not raised, the inside air with a sufficient gap between the end portion after trimming and the recessed portion of the vertical wall portion can be obtained. Since the introduction part can be formed, the height dimension from the bottom wall of the closed section to the trim can be made as small as possible without lowering the rigidity and the ventilation performance. As a result, the rear view can be expanded. Also, there is an advantage that the trunk volume can be increased at the same time.
