Description

[Technical Field]

[0001] The present invention relates to a side structure of a vehicle that is provided with a deflector that prevents wind from hitting a rear wheel while the vehicle is running. [Background technology]

[0002] Generally, in a vehicle side structure, a rear deflector 80 is attached to the rear end of a side sill garnish 81 as shown in Fig. 13 (see Patent Document 1). This rear deflector 80 prevents underfloor running wind from directly hitting rear wheels 82, and deflects the underfloor running wind to the outside of the rear wheels 82.

[0003] In this case, as shown in Figure 13, a portion of the side sill garnish 81 attached to the outside of the side sill 83 is protruded outward in the vehicle width direction to form a protruding portion 81a, thereby providing a seating surface for attaching the rear deflector 80 that protrudes outward in the vehicle width direction.

[0004] The vehicle must satisfy the requirement for ease of entry and exit that rear seat occupants must be able to exit the rear seat cushion even when the rear door 84 is half-open. Taking this requirement into consideration, it is preferable to eliminate the side sill garnish 81 that protrudes outward from the vehicle.

[0005] In the case of a side sill garnish 81 that does not have the above-mentioned protrusion 81a, a mounting seat surface for the rear deflector 80 cannot be ensured, and therefore, conventionally, a side structure shown in FIG. 14 has been adopted.

[0006] That is, in the conventional structure shown in FIG. 14, the outer end 81b of the side sill garnish 81 provided on the underside of the side sill 83 protrudes outward in the vehicle width direction to a position inside the lower end 84a of the hemmed portion between the door outer panel 85 and the door inner panel 86, and therefore, the mounting surface for the rear deflector 80 cannot be secured.

[0007] For this reason, in the conventional structure of Figure 14, an overfender 87 equivalent to a door garnish is attached to a vehicle body 88 located behind the rear door, as shown by the dotted line in Figure 15, and a rear deflector 80 is attached to the back of the lower end of this overfender 87.

[0008] In the case of a relatively small vehicle, as shown by the dotted line in FIG. 15, a rear seat occupant X (however, FIG. 15 shows the position of the pelvis of the rear seat occupant X) can get out of the vehicle by slipping through the gap between the door trim 90 and the over-fender 89 on the inside of the partially open rear door 84.

[0009] On the other hand, in the case of a large-sized vehicle shown by the solid line in Figure 15, the over-fender 89 is at position α in the figure, and when a rear seat occupant Y (however, Figure 15 shows the position of the pelvis of the rear seat occupant Y) slips through between the door trim 90 and the over-fender 89 of the partially open rear door 84 to get out of the vehicle, there is significant interference with the over-fender 89 at position α. ​​The vehicle shown by the solid line in Figure 15 is a relatively large-sized vehicle with a long door length and a wide body width. In Figure 15, 91 is a first pillar.

[0010] As described above, in the case of a large vehicle shown by the solid line in Figure 15, the over-fender 89 is at the position α shown in the figure, and when rear seat occupant Y (however, Figure 15 shows the position of the pelvis of rear seat occupant Y) slips through between the door trim 90 and the over-fender 89 of the partially open rear door 84 to get out of the vehicle, there is significant interference with the over-fender 89 at position α.

[0011] To solve this problem, even if the over-fender 89 at position α and the second pillar 88 (the pillar located further rearward than the first pillar) are moved to a position inward in the vehicle width direction as shown by position β, the over-fender 89 at position β will interfere with the rear seat occupant Y when the rear seat occupant Y gets out of the vehicle, so the over-fender 89 will have to be eliminated. If the over-fender 89 is eliminated, there will be no place to attach the rear deflector 80.

[0012] On the other hand, it is also possible to fix the rear deflector 80 directly to the body frame, but in this case, the amount of protrusion (protrusion) of the rear deflector 80 outward in the vehicle width direction relative to the fixing part of the rear deflector 80 becomes large, making it difficult to ensure sufficient rigidity of the rear deflector 80 against the wind generated when traveling under the floor, and there is a concern that the wind generated when traveling under the floor will directly hit the rear wheels 82, thereby deteriorating aerodynamic performance.

[0029] A structure for fixing a deflector to a large vehicle, which aims to achieve both ease of entry and exit for rear seat occupants and ensuring rigidity of the deflector against underfloor running wind, comprises a side sill extending in the front-rear direction of the vehicle at the lower outer side of the vehicle body in the vehicle width direction, an outer plate panel covering the outer side of the side sill, an attachment member provided at a predetermined position of the outer plate panel facing the rear wheel, and a deflector fixed to the attachment member, the region of which in the vehicle width direction outer than the outer end of the side sill overlaps with the rear wheel in a front view of the vehicle, and the attachment member is located below the rear seat surface and has a closed cross-sectional portion extending in the vertical direction in cooperation with the outer plate panel. The closed cross-sectional portion has a deflector mounting surface facing the rear wheel, and an outer end portion of the deflector mounting surface in the vehicle width direction is located outside an imaginary line passing through the center of the rear wheel in the vehicle width direction. This was achieved through the following configuration. [Example]

[0030] An embodiment of the present invention will be described in detail below with reference to the drawings. The drawings show the side structure of a vehicle, with Fig. 1 being a side view of the side structure of the vehicle with the side sill garnish attached, Fig. 2 being a perspective view of the side structure of the vehicle with the side sill garnish removed from Fig. 1, and Fig. 3 being a perspective view of the side structure of the vehicle with the cover of the mounting member removed from Fig. 2.

[0034] As shown in Figure 7, a floor panel 2 is provided to form the floor surface of the passenger compartment 1, and side sills 3 extending in the fore-and-aft direction of the vehicle are provided at both left and right ends of the floor panel 2 (however, only the end on the left side of the vehicle is shown in the drawing) on ​​the lower outside of the vehicle width direction.

[0035] This side sill 3 is a vehicle body rigidity member in which a side sill inner 4 and a side sill outer 5 are joined and fixed, and which has a side sill closed cross-sectional portion 6 extending in the fore-and-aft direction of the vehicle, and if necessary, a side sill reinforcement is provided between the side sill inner 4 and the side sill outer 5.

[0036] A floor frame 7 having an L-shaped cross section when viewed from the front of the vehicle is joined and fixed between the underside of the floor panel 2 and the vehicle width direction inner surface of the side sill inner panel 4 of the side sill 3. The floor panel 2, side sill inner panel 4, and floor frame 7 cooperate to form a floor frame closed cross section 8 that extends in the fore-and-aft direction of the vehicle, thereby improving the rigidity of the lower vehicle body.

[0037] 1, a rear seat 9 serving as a rear seat is mounted above the floor panel 2. The rear seat 9 includes a seat cushion 10 that forms a seating surface (rear seat surface) 9a for the rear seat passenger, a seat back 11 that forms a backrest surface for the rear seat passenger, and a headrest (not shown) that supports the head of the rear seat passenger.

[0038] As shown in Figures 4 to 7, a wheel house 13 (more specifically, a rear wheel house) is provided on the outer side of the floor panel 2 in the vehicle width direction and at the rear of the above-mentioned side sill 3, spaced apart from the rear wheel 12 and covering the upper majority of the rear wheel 12.

[0039] As shown in Figures 4, 5 and 6, the wheel house 13 is formed by joining and fixing a wheel house inner 14 located on the inside in the vehicle width direction and a wheel house outer 15 located on the outside in the vehicle width direction. As shown in FIGS. 1 to 7, an outer panel (so-called cab side outer) 20 is provided to cover at least the side sill 3 on the outer side of the vehicle.

[0040] As shown in FIG. 1, the above-mentioned outer plate panel 20 is integrally formed with at least a side sill portion 21 that covers the vehicle exterior side of the side sill outer 5, a wheel house portion 22 that covers the vehicle exterior side of the wheel house outer 15, a second pillar portion that covers the vehicle exterior side of the second pillar (see second pillar 88 shown by solid lines in FIG. 15), and a rear fender panel portion 23.

[0041] As shown in Figures 1 and 7, a first weather strip WS1 that seals between the body side and the rear door side (see rear door 84 shown by solid lines in Figure 15) is fitted and fixed along the edge of the rear door opening 16 to the flange portions of the side sill inner 4, side sill outer 5, and exterior panel 20, which form the rear door opening 16 through which rear seat passengers get in and out.

[0042] Although the drawings only show the flange portions of the side sill inner 4, side sill outer 5, and exterior panel 20, the rear door opening 16 is formed in conjunction with the flange portions (not shown) of the second pillar, roof side rail, and first pillar.

[0043] 1 and 7, a second weatherstrip WS2 that seals the gap between the body side and the rear door side is provided on the outer surface of the outer panel 20, on the outer peripheral side of the first weatherstrip WS1. This second weatherstrip WS2 is provided along the first weatherstrip WS1.

[0044] 1, 2, and 4 to 6, a third weatherstrip WS3 is provided along the wheel arch in the wheelhouse portion 22 of the outer panel 20, and a front lower portion of this third weatherstrip WS3 is located on the outer surface side in the vehicle width direction of a cover 33 of the mounting member 30, which will be described later. This third weatherstrip WS3 also seals between the body side and the rear door side, and is formed by molding.

[0045] 1, 2, and 8(a), a recess 22b is formed in a predetermined position of the outer plate panel 20 facing the rear wheel 12, i.e., at the rear end position of the side sill portion 21 of the outer plate panel 20 and at a lower front position of the wheel house portion 22. The recess 22b is curved inward in the vehicle width direction relative to the base surface 22a of the wheel house portion 22. As shown in FIGS. 4 and 10, a mounting member 30 is provided in the recess 22b using a plurality of fixing members 24.

[0046] As shown in Fig. 8, a deflector (more specifically, a rear deflector) 50 is attached to the mounting member 30. The region of this deflector 50 that is outward in the vehicle width direction from the outer end of the side sill 3 in the vehicle width direction overlaps with the rear wheel 12 in a front view of the vehicle, as shown in Fig. 7.

[0047] 1, the mounting member 30 is positioned below the rear seat surface 9a, and as shown in FIGS. 4 and 5, has a closed cross-sectional portion S1 that extends in the vertical direction in cooperation with the outer panel 20. However, the closed cross-sectional portion S1 allows for an interference prevention gap for assembly.

[0048] 4 and 5, an interference prevention gap g is formed between the outer rear end 15a in the vehicle width direction of the wheel house outer 15 and a rear wall 32c of a second member 32 (described later) of the mounting member 30 in order to allow the mounting member 30 to be assembled to the body. The closed cross-sectional portion S1 described above allows for this interference prevention gap g.

[0049] In this way, by positioning the mounting member 30 below the rear seat surface 9a (see Figure 1), it does not hinder rear seat passengers from getting in and out when the rear door (see rear door 84 shown by solid lines in Figure 15) is half open.

[0050] Furthermore, the deflector 50, which prevents underfloor traveling wind from hitting the rear wheels 12, extends outward in the vehicle width direction from the outer panel 20 to a position that overlaps with the rear wheels 12 in a front view of the vehicle. Even when such a deflector 50 is used, by attaching the deflector 50 to the closed cross-sectional portion S1 (see Figures 4 and 5) that extends in the vertical direction, the deflector 50 is configured to ensure rigidity against underfloor traveling wind even in the case of a deflector 50 whose area outside the outer panel 20 overlaps with the rear wheels 12.

[0051] 4 to 6 and 10, the mounting member 30 includes the outer plate panel 20, in particular a first member 31 provided along the recess 22b thereof, a second member 32 positioned outside the first member 31, and a cover 33 that closes an opening 32a formed in the outer surface of the second member 32 in the vehicle width direction. The first member 31, the second member 32, and the outer plate panel 20 cooperate to form the closed cross-sectional portion S1 extending in the vertical direction of the vehicle.

[0052] As a result, compared to a mounting member 30 configured from a single member, the mounting member 30 is configured to improve the rigidity of the entire mounting member 30 while ensuring the rigidity of the mounting portion at each location.

[0053] As shown in FIG. 10, the first member 31 of the mounting member 30 has an outer wall 31a extending vertically on the outer side in the vehicle width direction, and a rear wall 31b extending from the rear end of the outer wall 31a toward the inner side in the vehicle width direction.

[0054] As shown in Figures 10 and 11, the second member 32 of the mounting member 30 has an outer wall 32b extending in the vertical direction on the outer side of the vehicle width direction, a rear wall 32c extending from the rear end of the outer wall 32b toward the inner side of the vehicle width direction, and a bottom wall 32d connecting the lower part of the outer wall 32b and the lower part of the rear wall 32c.

[0055] As is clear from FIG. 10, the vertical length of the outer wall 32b of the second member 32 is longer than the vertical length of the outer wall 31a of the first member 31. Also, as shown in the same figure, the vertical length and the vehicle width length of the rear wall 32c of the second member 32 are both larger than the vertical length and the vehicle width length of the rear wall 31b of the first member 31.

[0056] 8(b), the rear wall 32c of the second member 32 is formed in a substantially right-angled triangle shape when viewed from the rear of the vehicle. Specifically, the right-angled triangle is configured in such a shape that the base is located at the bottom, the hypotenuse is located on the inside in the vehicle width direction, and the opposite side is located on the outside in the vehicle width direction.

[0057] Furthermore, as shown in FIG. 4, at the position where the above-mentioned fixing member 24 is provided, the first member 31 is formed with a recess 31c recessed inward in the vehicle width direction, and the second member 32 is formed with a protrusion 32e that fits into the recess 31c, so that when the mounting member 30 is fixed to the outer panel 20, the protrusion 32e fits into the recess 31c, thereby positioning the members 31, 32.

[0058] As shown in FIGS. 10 and 11, the recessed portions 31c and the protruding portions 32e are provided in plural on the outer wall 31a of the first member 31 and the outer wall 32b of the second member 32, spaced apart in the vertical direction.

[0059] 10 and 11, lower rear wall 32f, which is a lower part of rear wall 32c of second member 32, extends downward via step portion 32g toward the front of the vehicle relative to rear wall 32c. As a result, when deflector 50 is fixed to mounting member 30, rear wall 32c of second member 32 and the back side of deflector 50 are formed flush with each other, as shown in FIGS.

[0060] 10, an upper wall 31d extending in the vehicle width direction to face the bottom wall 32d of the second member 32, and a front wall 31e extending downward from the front end of the upper wall 31d are integrally formed at the lower part of the rear wall 31b of the first member 31. The upper wall 31d and the front wall 31e of the first member 31 and the lower rear wall 32f and the bottom wall 32d of the second member 32 form a second closed cross-sectional portion S2 extending in the vehicle width direction.

[0061] That is, the first member 31 and the second member 32 cooperate with each other to form a second closed cross-sectional portion S2 at the lower portion of the mounting member 30, extending in the vehicle width direction. The second closed cross-sectional portion S2 is configured to improve the rigidity of the mounting member 30, particularly the rigidity of the lower portion of the mounting member 30.

[0062] As shown in FIG. 10, the first member 31 is provided with an inner wall 31f that connects the inner end in the vehicle width direction of the upper wall 31d and the inner end in the vehicle width direction of the front wall 31e. As shown in Figures 10 and 11, an engagement protrusion 34 is formed on one of the first member 31 and the second member 32 that form the second closed cross-sectional portion S2, specifically on the bottom wall 32d of the second member 32.

[0063] Further, the other of the first member 31 and the second member 32, specifically the inner wall 31f of the first member 31, is formed with an engagement hole 35 that engages with the engagement protrusion 34. As a result, the engagement structure between the engagement projections 34 and the engagement holes 35 described above is configured to suppress so-called rattle, which is the undesired behavior of the first member 31 and the second member 32 when the vehicle is running.

[0064] Here, the lower rear wall 32f of the second member 32 described above constitutes the deflector rear mounting surface 36 as the deflector mounting surface facing the rear wheel 12, and the bottom wall 32d constitutes the deflector lower mounting surface 37.

[0065] As shown in Figure 9, the deflector 50 is integrally formed with a deflector body 51, an upper mounting portion 52 extending upward from the deflector body 51, and a front mounting portion 53 extending forward of the vehicle from the lower end of the upper mounting portion 52 (in other words, the boundary between the upper end of the deflector body 51 and the lower end of the upper mounting portion 52).

[0066] As shown in Figure 9(b), a rib 54 extending a predetermined length from the entire peripheral edge of the deflector body 51 toward the rear of the vehicle is integrally formed on the rear side of the deflector body 51, thereby improving the rigidity of the deflector 50.

[0067] As shown in Figures 8(b) and 11, the upper mounting portion 52 of the deflector 50 is fixed to the deflector rear mounting surface 36 of the second member 32 of the mounting member 30 using multiple fixing members 55 spaced apart in the vehicle width direction.

[0068] As shown in Figures 8(a) and 11, the front mounting portion 53 of the deflector 50 is fixed to the deflector lower mounting surface 37 of the second member 32 of the mounting member 30 using multiple fixing members 56 spaced apart in the vehicle width direction. In other words, the deflector 50 is attached to the outer panel 20 via the attachment member 30 .

[0069] As shown in Figures 4 to 8, the closed cross-sectional portion S1 has a deflector rear mounting surface 36 facing the rear wheel 12, and the vehicle width direction outer end portion 36a (see Figure 7) of the deflector rear mounting surface 36 is located outside the vehicle width direction of an imaginary line CL that passes through the vehicle width center of the rear wheel 12 and extends in the fore-and-aft direction of the vehicle. This ensures a sufficient length of the deflector rear mounting surface 36 in the vehicle width direction, while restricting the amount of protrusion of the deflector 50 outward from the vehicle.

[0070] As shown in FIGS. 4 and 5, the closed cross-sectional portion S1 is formed so that the vehicle width direction dimension of its rear end is larger than the vehicle width direction dimension of its front end. This allows the vehicle width direction dimension of the deflector rear mounting surface 36 located on the rear surface of the mounting member 30 to be increased, ensuring the mounting rigidity of the deflector 50 while suppressing the amount of protrusion of the deflector 50 outward from the deflector rear mounting surface 36.

[0071] 4 and 5, the mounting member 30 described above cooperates with the outer plate panel 20 to form a space SP that is substantially triangular in plan view of the vehicle. This space SP coincides with the closed cross-sectional portion S1. The second member 32 of the mounting member 30 that forms the substantially triangular space SP in a plan view of the vehicle described above has an obtuse corner OA on the front side of the second member 32 and on the outer side in the vehicle width direction.

[0072] In this way, the mounting member 30 cooperates with the outer panel 20 to form a space SP that is approximately triangular in shape when viewed from above the vehicle, thereby improving the rigidity of the mounting member 30 through a truss structure.

[0073] As shown in Figures 1, 11, and 12, a side sill garnish 40 extending in the fore-and-aft direction of the vehicle along the side sill outer 5 is provided on the vehicle width outer side of the side sill portion 21 of the outer panel 20 corresponding to the side sill 3. As shown in FIG. 11, the side sill garnish 40 includes an outer wall 41 located on the outer side in the vehicle width direction, and a bottom wall 42 extending from the lower end of the outer wall 41 toward the inner side in the vehicle width direction.

[0074] Furthermore, the rear portion of the side sill garnish 40 overlaps a portion of the bottom wall 32d of the second member 32 of the mounting member 30 in the vehicle vertical direction. The overlapping portion of both the side sill garnish 40 and the side sill garnish 40 is attached to the bottom wall 32d of the second member 32 by a fixing member 43. The fixing member 43 forms a garnish mounting portion 44 between the side sill garnish 40 and the mounting member 30.

[0075] Furthermore, as shown in FIG. 12, the rear end 41a of the outer wall 41 of the side sill garnish 40 is configured to be located more inward in the vehicle width direction than the front end 32b1 of the outer wall 32b of the second member 32 and further rearward of the vehicle.

[0076] 11, the deflector rear mounting surface 36 is located near the garnish mounting portion 44 that mounts the side sill garnish 40 and the mounting member 30. This allows the load input from the deflector 50 to the mounting member 30 to be transmitted to the side sill garnish 40 via the garnish mounting portion 44, thereby dispersing the load.

[0077] 11, the above-mentioned deflector rear mounting surface 36 is located at approximately the same height as the garnish mounting portion 44 that mounts the side sill garnish 40 and the mounting member 30. As a result, the load input from the deflector 50 to the mounting member 30 is transmitted to the side sill garnish 40 via the garnish mounting portion 44, dispersing the load and improving the durability of the mounting member 30.

[0078] 11, the deflector rear mounting surface 36 serving as the deflector mounting surface is provided to overlap, in a rear view of the vehicle, with the garnish mounting portion 44 that mounts the side sill garnish 40 and the mounting member 30. This allows the load input from the deflector 50 to the mounting member 30 to be transmitted to the side sill garnish 40 via the garnish mounting portion 44, dispersing the load and improving the durability of the mounting member 30.

[0079] The first member 31 of the above-described mounting member 30 is formed, for example, by a TOM (Three Dimension Overlay Method) molded product, that is, a molded product in which a film is tightly fixed to the surface of a substrate.

[0080] The second member 32 of the above-described mounting member 30 is formed of, for example, EPDM (ethylene-propylene-diene-methylene rubber, an ethylene-propylene copolymer).

[0081] Furthermore, the above-mentioned deflector 50 is formed of, for example, TPE (thermoplastic elastomer). Note that the TOM molded product, EPDM, and TPE that form the first member 31, the second member 32, and the deflector 50 are merely examples, and the present invention is not limited to these.

[0082] In this embodiment, the configurations of the first pillar, second pillar, and rear door are the same as those shown by the solid lines in Fig. 15. Furthermore, in the figure, arrow F indicates the front of the vehicle, arrow R indicates the rear of the vehicle, arrow IN indicates the inside in the vehicle width direction, arrow OUT indicates the outside in the vehicle width direction, and arrow UP indicates the top of the vehicle.

[0083] As described above, the vehicle side structure according to this embodiment comprises the side sill 3 extending in the longitudinal direction of the vehicle at the lower outer side of the vehicle body in the vehicle width direction, the outer panel 20 covering the outer side of the side sill 3, the mounting member 30 provided at a predetermined position of the outer panel 20 facing the rear wheel 12, and the deflector 50 fixed to the mounting member 30, the region of the deflector 50 that is outward in the vehicle width direction from the outer end of the side sill 3 in the vehicle width direction overlapping with the rear wheel 12 in a front view of the vehicle, and the mounting member 30 is located below the rear seat cushion 9a and is characterized by comprising a closed cross-sectional portion S1 that extends in the vertical direction in cooperation with the outer panel 20 (see FIGS. 1, 4, and 7).

[0084] According to such a vehicle side structure, the mounting member 30 is positioned below the rear seat surface 9a, and therefore does not impede the rear seat passengers from getting in and out when the rear door is half-open.

[0085] Furthermore, even if a deflector 50 is employed that extends outward in the vehicle width direction from the outer panel 20 to a position that overlaps with the rear wheel 12 when viewed from the front of the vehicle, and that prevents underfloor traveling wind from hitting the rear wheel 12, by attaching the deflector 50 to the closed cross-sectional portion S1 that extends in the vertical direction, rigidity against underfloor traveling wind can be ensured even in the case of a deflector 50 whose area outside the outer panel 20 overlaps with the rear wheel 12.

[0086] In addition, in such a vehicle side structure, the closed cross-sectional portion S1 has a deflector mounting surface (deflector rear mounting surface 36) facing the rear wheel 12, and the vehicle width direction outer end portion of the deflector mounting surface (deflector rear mounting surface 36) is located outside an imaginary line CL passing through the vehicle width direction center of the rear wheel 12 (see Figures 4 to 6 and Figure 8).

[0087] According to such a vehicle side structure, it is possible to suppress the amount of protrusion of the deflector 50 outward from the vehicle while ensuring a sufficient length in the vehicle width direction of the deflector mounting surface (deflector rear mounting surface 36).

[0088] Furthermore, in this vehicle side structure, the closed cross-sectional portion S1 has a rear end portion whose vehicle width dimension is larger than the front end portion (see FIGS. 4 and 5).

[0089] According to this type of vehicle side structure, the vehicle width dimension of the deflector mounting surface (deflector rear mounting surface 36) can be increased, thereby ensuring the mounting rigidity of the deflector 50 and reducing the amount of protrusion of the deflector 50 from the deflector mounting surface (deflector rear mounting surface 36).

[0090] Furthermore, in this vehicle side structure, the mounting member 30 cooperates with the outer plate panel 20 to form a space SP that is substantially triangular in plan view of the vehicle (see FIGS. 4 and 5).

[0091] According to such a vehicle side structure, the mounting member 30 cooperates with the outer plate panel 20 to form a space SP that is substantially triangular in plan view of the vehicle, so that the rigidity of the mounting member 30 can be improved.

[0092] Additionally, in such a vehicle side structure, the mounting member 30 comprises a first member 31 provided along the outer plate panel 20 and a second member 32 positioned outside the first member 31, and the first member 31, the second member 32, and the outer plate panel 20 cooperate to form the closed cross-sectional portion S1 (see Figures 4 to 6).

[0093] According to such a vehicle side structure, compared to a mounting member made of a single member, it is possible to improve the rigidity of the mounting member 30 while ensuring the rigidity of the mounting portion at each location.

[0094] In addition, in such a vehicle side structure, the deflector mounting surface (deflector rear mounting surface 36) is located near the garnish mounting portion 44 that mounts the side sill garnish 40 and the mounting member 30 (see Figures 1, 11, and 12). According to such a vehicle side structure, the load input from the deflector 50 can be transmitted to the side sill garnish 40, thereby dispersing the load.

[0095] Furthermore, in such a vehicle side structure, the deflector mounting surface (deflector rear mounting surface 36) is located at approximately the same height as the garnish mounting portion 44 to which the side sill garnish 40 and the mounting member 30 are attached (see Figures 1, 11, and 12). According to such a vehicle side structure, the load input from the deflector 50 can be transmitted to the side sill garnish 40, thereby dispersing the load.

[0096] Furthermore, in such a vehicle side structure, the deflector mounting surface (deflector rear mounting surface 36) is provided so as to overlap, when viewed from the rear of the vehicle, with the garnish mounting portion 44 that mounts the side sill garnish 40 and the mounting member 30 (see Figures 1, 11, and 12). According to such a vehicle side structure, the load input from the deflector 50 can be transmitted to the side sill garnish 40, thereby dispersing the load.

[0097] In addition, in such a vehicle side structure, a second closed cross-sectional portion S2 is formed at the lower part of the mounting member 30, extending in the vehicle width direction in cooperation with the first member 31 and the second member 32 (see Figure 10). According to such a vehicle side structure, the rigidity of the lower part of the mounting member 30 can be improved by the second closed cross-sectional portion S2.

[0098] Furthermore, in such a vehicle side structure, an engagement protrusion 34 is formed on one of the first member 31 and the second member 32 that form the second closed cross-sectional portion S2, and an engagement hole 35 that engages with the engagement protrusion 34 is formed on the other of the first member 31 and the second member 32 (see Figures 10 and 11).

[0099] According to such a vehicle side structure, the engagement structure between the engagement projections 34 and engagement holes 35 can suppress so-called rattle, which is undesired behavior of the first member 31 and the second member 32 when the vehicle is traveling.
