Description
This application claims priority based on Japanese patent application No. 2021-036243 filed on 8/3/2021, the contents of which are incorporated herein by reference.
Technical Field
The present invention relates to a vehicle body structure.
Background
As a rear wheel house of a vehicle body structure, a structure is known in which respective flanges of a wheel house inner panel and a wheel house outer panel are joined, and the wheel house inner panel and the wheel house outer panel are joined by an extension plate. Here, the respective flanges of the wheel house inner panel and the wheel house outer panel are joined by so-called "butt joint".
With this vehicle body structure, for example, a load in the vehicle width direction is likely to be input to the rear wheel house due to twisting of the vehicle body or the like during traveling of the vehicle. In this case, the extension plate can suppress the separation of the flanges of the wheel house inner panel and the wheel house outer panel (see, for example, japanese patent No. 4368300).
Disclosure of Invention
In the vehicle body structure of japanese patent No. 4368300, only a part of the wheel house inner panel and the wheel house outer panel is joined by the extension panel. Therefore, in order to ensure the strength and rigidity of the vehicle body, it is necessary to suppress the peeling over the entire periphery of each flange of the wheel house inner panel and the wheel house outer panel.
However, in order to suppress the separation of the flanges of the wheel house inner panel and the wheel house outer panel over the entire periphery thereof, it is necessary to apply the joining by the extension plate (reinforcing member) over the entire periphery of the flanges. Therefore, assembly of the vehicle body becomes very complicated, and the vehicle body weight increases.
The invention provides a vehicle body structure which can simplify assembly and reduce the weight of a vehicle body and can improve the strength and rigidity of the vehicle body.
The present invention proposes the following.
(1) The vehicle body structure according to the present invention includes: a first member formed in a U-shaped cross section having a first opening; a second member formed in a U-shaped cross section having a second opening, the second member being disposed opposite to the first member such that the first opening and the second opening face each other, one of the first member and the second member including: a flared portion that is inclined so that an opening thereof increases toward one of the first opening and the second opening; and an inclined flange inclined in a direction opposite to the expanded portion such that an opening decreases from the expanded portion to the one opening portion, wherein the other of the first member and the second member has an inclined side wall inclined to the other of the first opening portion and the second opening portion along the inclined flange, and the inclined flange and the inclined side wall are joined in a fitted state.
According to the configuration of the aspect (1), the first member and the second member are formed to have U-shaped cross sections, respectively, and one member has the expanded portion and the inclined flange, and the other member has the inclined side wall. The inclined flange of one member is joined to the inclined side wall of the other member in a fitted state.
Here, when the first member and the second member are joined, for example, the first opening and the second opening may be displaced. In this case, a portion of the inclined flange is in contact with a portion of the inclined sidewall. In this state, the engagement of the first member with the second member is continued. Thus, the portion of the inclined flange and the portion of the inclined side wall that are in contact with each other serve as guides, and can be positioned so as to approach each other in a direction in which the other portion of the inclined flange and the other portion of the inclined side wall are in contact with each other.
This makes it possible to bring both the inclined flange and the inclined side wall into contact over the entire area, and to join the inclined flange and the inclined side wall at the correct position. Therefore, simplification of assembly of the first member and the second member can be achieved.
However, a case where a load is input in the joining direction of the first member and the second member is conceivable. In this case, the inclined flange and the inclined side wall are joined in the direction of receiving the shear load. Thus, the inclined flange and the inclined side wall can be firmly joined without using, for example, a reinforcing member, so that the inclined flange and the inclined side wall can be prevented from being peeled off by a load input in the joining direction of the first member and the second member. Thus, by using the first member and the second member in the vehicle body, the vehicle body can be reduced in weight, and the strength and rigidity of the vehicle body can be improved.
Hereinafter, the joining of the inclined flange and the inclined side wall in the direction receiving the shear load may be referred to as "shear-mating" joining.
(2) In the aspect (1), the one member may have a ridge portion formed at an intersection of the inclined flange and the expanded portion, and the other member may have a reinforcing flange formed at a portion corresponding to the ridge portion and protruding in a direction away from the ridge portion.
According to the structure of the aspect (2), the ridge line portion is formed at the intersection of the inclined flange and the expanded portion of one member. The other member is formed with a reinforcing flange projecting in a direction away from the ridge portion at a portion corresponding to the ridge portion. Thus, the inclined side wall is reinforced by the reinforcing flange, and the inclined side wall can be firmly joined to the inclined flange. Thus, the strength and rigidity of the vehicle body can be easily improved with a simple structure by using the first member and the second member in the vehicle body.
(3) In the aspect (2), the other member may have another ridge line portion formed at an intersection of the inclined side wall and the reinforcing flange, the other ridge line portion being provided at a position overlapping the ridge line portion in a joining direction of the first member and the second member.
According to the structure of the aspect (3), another ridge line portion is formed at the intersection of the inclined side wall of the other member and the reinforcing flange. The first member and the second member are disposed at positions overlapping the ridge portions in the joining direction. Thus, by using the first member and the second member in the vehicle body, for example, the other ridge line portion can be arranged at a position overlapping with the ridge line portion in the vehicle width direction. This makes it possible to suppress vibration in the vehicle width direction received (input) during traveling of the vehicle at both the other ridge line portion and the ridge line portion, and to improve the strength and rigidity of the vehicle body.
(4) In the aspect (1), the one member may be a wheel house inner panel forming an inner portion in the vehicle width direction in the wheel house, the other member may be a wheel house outer panel forming an outer portion in the vehicle width direction in the wheel house, and the inclined flange may be provided over an entire circumference of the wheel house.
According to the structure of the aspect (4), the inclined flange is provided over the entire periphery of the wheel house. This enables the inclined flange to be joined to the inclined side wall over the entire periphery of the wheel house. Thus, when vibration in the vehicle width direction is input from the suspension during traveling of the vehicle, vibration of the wheel house can be suppressed by the joint portion of the inclined flange and the inclined side wall, and the strength and rigidity of the vehicle body can be improved.
(5) In the aspect (4), the wheel house may be provided on the left and right sides in the vehicle width direction with a space therebetween, and the vehicle body structure may include a small article cross member connected to the left and right wheel houses, the small article cross member being joined to the inclined flange and the inclined side wall in a state of being overlapped with each other at an upper portion of the wheel house.
According to the structure of the aspect (5), the small article cross member is connected to the left and right wheel houses. In addition, the small article cross member is overlapped with the inclined flange and the inclined side wall at the upper part of the wheel cover, and the overlapped three members (three pieces) are jointed. Thus, the small article beam can be firmly joined to the inclined flange and the inclined side wall. Further, the left and right wheel houses are joined by, for example, shearing engagement between the inclined flange and the inclined side wall, and the strength and rigidity can be improved against vibration in the vehicle width direction.
Accordingly, the small member cross member can be firmly joined to the upper portions of the left and right wheel houses, and the upper portions of the left and right wheel houses can be firmly connected by the small member cross member, whereby the strength and rigidity of the vehicle body can be further improved.
According to the present invention, the assembly can be simplified and the vehicle body can be reduced in weight, and the strength and rigidity of the vehicle body can be improved.

< vehicle body Structure >
As shown in fig. 1 and 2, the vehicle body structure 10 includes, for example, left and right rear frames 12, left and right rear wheel houses (wheel houses) 14, and a rear partition wall 15.
The left and right rear frames 12, 12 extend rearward of the vehicle body from rear end portions of the left and right rocker 17 (see fig. 10). The left and right rocker 17 extends in the vehicle longitudinal direction along both vehicle width direction side portions of a floor 22 forming a floor portion of the vehicle compartment 21, and constitutes a part of the vehicle body frame. The left and right rear frames 12, 12 extend in the vehicle body front-rear direction along both vehicle width direction side portions of a rear floor 25 forming a floor portion of the luggage compartment 24, and constitute a part of the vehicle body frame.
The left and right rear wheel houses 14, 14 are disposed at a distance from each other on the left and right sides in the vehicle width direction by the left and right rear frames 12, 12 and the rear partition wall 15. In this state, the left and right rear wheel houses 14, 14 are disposed on the vehicle width direction outer sides of the left and right rear frames 12, and the lower end portions 14a, 14a are provided on the left and right rear frames 12, respectively.
The left and right rear wheel houses 14, 14 are substantially bilaterally symmetrical members, and hereinafter, the left rear wheel house 14 will be described in detail, and the detailed description of the right rear wheel house 14 will be omitted. The constituent members of the left and right rear wheel housings 14, 14 are denoted by the same reference numerals, and the left rear wheel housing 14 is simply referred to as "rear wheel housing 14". The rear wheel house 14 will be described in detail later.
The rear bulkhead 15 is provided between the rear floor 25 and the left and right rear frames 12, 12 and the left and right rear wheel houses 14, 14. The rear partition wall 15 is formed in a downward ring shape in a front view, and constitutes a part of the vehicle body frame.
The rear bulkhead 15 includes left and right side members (legs) 31, a lower cross member (cross member) 32, and an upper cross member (small article cross member, cross member) 33.
The left and right side members 31, 31 rise from the left and right rear frames 12, 12 to the left and right end portions of the upper cross member 33 so as to be inclined upward toward the rear of the vehicle body. The lower cross member 32 extends along the rear floor 25 and in the vehicle width direction between lower end portions of the left and right side members 31, 31. The upper cross member 33 extends in the vehicle width direction along the front end portion of the small article frame 35 between the upper end portions of the left and right side members 31, 31.
< rear wheel house >
As shown in fig. 3 to 5, the rear wheel house 14 includes a wheel house inner panel (one of the first member and the second member, the inner member) 41 and a wheel house outer panel (the other of the first member and the second member, the outer member) 42.
The wheel house inner panel 41 is a panel that forms an inner portion in the vehicle width direction of the rear wheel house 14. The wheel house inner panel 41 is formed in a substantially U-shaped cross section (including a U-shaped cross section), and has an inner opening portion (one of the first opening portion and the second opening portion) 43, an expanded portion 44, an inclined flange 45, and an inner ridge portion (ridge portion) 46.
The inner opening portion 43 is formed at an outer end portion in the vehicle width direction of the wheel house inner panel 41, and opens outward in the vehicle width direction. The inner opening portion 43 is formed over the entire periphery of the wheel house inner panel 41 (i.e., the rear wheel house 14).
The expanding portion 44 is inclined so that the opening gradually expands toward the inner opening portion 43 at a portion close to the inner opening portion 43.
The inclined flange 45 is inclined in the opposite direction with respect to the flared portion 44 so that the opening thereof gradually decreases from the outer end of the flared portion 44 to the inner opening portion 43. The flared portion 44 and the inclined flange 45 are bent in a V-shape in cross section so as to project outward of the wheel house inner panel 41.
The inner ridge line portion 46 is formed in a ridge line shape protruding outward of the wheel house inner panel 41 at the intersection of the inclined flange 45 and the expanded portion 44.
Here, the expanded portion 44, the inclined flange 45, and the inner ridge portion 46 are provided over the entire circumference of the wheel house inner panel 41 (i.e., the rear wheel house 14), for example, from the front end portion 41a to the rear end portion 41b of the wheel house inner panel 41.
The wheel house outer panel 42 is a panel that forms an outer portion in the vehicle width direction in the rear wheel house 14. The wheel house outer panel 42 is formed in a substantially U-shaped cross section (including a U-shaped cross section), and has an outer opening portion (the other of the first opening portion and the second opening portion) 51, an inclined side wall 52, a reinforcing flange 53, and an outer ridge portion (the other ridge portion) 54.
The outer opening 51 is formed at an end portion of the wheel house outer panel 42 on the inner side in the vehicle width direction. The outer opening 51 is formed in the entire periphery of the wheel house outer panel 42 (i.e., the rear wheel house 14). The outer opening 51 is open inward in the vehicle width direction so as to face the inner opening 43. Specifically, the wheel house outer panel 42 is disposed with respect to the wheel house inner panel 41 so as to face the inner opening 43 and the outer opening 51. The outer opening 51 is larger than the inner opening 43 so that the inner opening 43 can be inserted therein.
The inclined side wall 52 is formed so as to cover the inclined flange 45 from the outside. Specifically, the inclined side wall 52 is inclined along the inclined flange 45 at a portion near the outer opening 51 so that the opening gradually expands to the outer opening 51. That is, the inclined side wall 52 is inclined in parallel with respect to the inclined flange 45.
The inclined flange 45 of the wheel house inner panel 41 is inserted into the inclined side wall 52 by inserting the inner opening 43 (i.e., the inclined flange 45) of the wheel house inner panel 41 from the outer opening 51. The outer peripheral surface of the inclined flange 45 is in contact with the inner peripheral surface of the inclined side wall 52, and in this state, the outer peripheral surface of the inclined flange 45 is joined to the inner peripheral surface of the inclined side wall 52. In other words, the inclined flange 45 and the inclined side wall 52 are joined by "shear alignment" described later in a state of being fitted.
Here, during traveling of the vehicle, for example, a load due to vibration in the vehicle width direction is input from a suspension (not shown) to the rear wheel house 14. The suspension supports the upper end portion, for example, on the upper portion 14b of the rear wheel house 14. Thereby, the load generated by the vibration is input substantially in the joining direction (X direction) of the inclined flange 45 and the inclined side wall 52. That is, the inclined flange 45 and the inclined side wall 52 are joined in the direction of receiving the shear load. Hereinafter, the joining of the inclined flange 45 and the inclined side wall 52 in the direction of receiving the shear load may be referred to as "joining by shear mating". The vehicle width direction substantially coincides with the joining direction of the wheel house inner panel 41 and the wheel house outer panel 42.
Hereinafter, for convenience of understanding the structure, the vehicle width direction will be described as being aligned with the joining direction of the wheel house inner panel 41 and the wheel house outer panel 42.
As shown in fig. 4 to 6, the reinforcing flange 53 is formed by bending at a portion corresponding to the inner ridge line portion 46 or the vicinity of the inner ridge line portion 46 so as to intersect with the inclined side wall 52. The reinforcing flange 53 extends to protrude in a direction away from the inner ridge line portion 46 toward the outside of the rear wheel house 14. The reinforcing flange 53 and the inclined side wall 52 are bent in a V-shape in cross section.
The outer ridge portion 54 is formed in a ridge shape by an intersection of the inclined side wall 52 and the reinforcing flange 53. The outer ridge line portion 54 is provided at a position overlapping the inner ridge line portion 46 in the joining direction (i.e., the vehicle width direction) of the wheel house inner panel 41 and the wheel house outer panel 42.
Here, the inclined side walls 52, the reinforcing flanges 53, and the outer ridge line portion 54 are provided over the entire circumference of the wheel house outer panel 42 (i.e., the rear wheel house 14), for example, from the front end portion 42a to the rear end portion 42b of the wheel house outer panel 42.
As shown in fig. 1 and 7, the left and right rear wheel houses 14 and 14 are connected to the upper cross member 33. Specifically, the upper cross member 33 is provided with left and right corner plates 61 at the left and right ends, respectively. The left and right gussets 61, 61 receive loads input from the left and right suspensions, transmit the loads to the upper cross member 33 connecting the left and right sides of the vehicle, and ensure rigidity of the entire vehicle.
Specifically, the left gusset 61 is joined to the upper end portion 31a of the left side member 31. The left gusset 61 is provided at the upper portion 14b of the left rear wheel house 14 so as to sandwich the left end portion 61a between the inclined flange 45 and the inclined side wall 52. The left end portion 61a of the left gusset 61, the inclined flange 45, and the inclined side wall 52 are joined to the upper portion 14b of the left rear wheel house 14 in a state in which three members (three sheets) are superposed on each other.
The right gusset 61 is a member substantially bilaterally symmetrical to the left gusset 61. The right gusset 61 is joined to the upper end portion 31a of the right side member 31. Similarly to the left gusset 61, the right gusset 61 sandwiches a right end portion (not shown) of the upper portion 14b of the right rear wheel house 14 between the inclined flange 45 and the inclined side wall 52. The right end portion of the right gusset 61, the inclined flange 45, and the inclined side wall 52 are joined to the upper portion 14b of the right rear wheel house 14 in a state where three members (three sheets) are superposed on each other.
Next, a procedure of assembling the rear wheel house 14 will be described with reference to fig. 8 and 9. As shown in fig. 8, when the wheel house inner panel 41 and the wheel house outer panel 42 are assembled (joined), for example, the inner opening portion 43 and the outer opening portion 51 may be displaced in the vehicle body front-rear direction or the vertical direction.
In this case, a part (one side) 45a of the inclined flange 45 of the wheel house inner panel 41 contacts a part (one side) 52a of the inclined side wall 52 of the wheel house outer panel 42. In this state, the joining of the wheel house inner panel 41 and the wheel house outer panel 42 is continued.
As shown in fig. 9, the inclined flange 45 is inclined such that the opening is gradually reduced from the outer end of the flared portion 44 to the inner opening portion 43. The inclined side wall 52 is inclined along the inclined flange 45 so that the opening gradually widens to the outer opening 51. Thus, the portion 45a of the inclined flange 45 and the portion 52a of the inclined side wall 52 that are in contact with each other serve as guides, and can be positioned so as to approach each other along the direction in which the other portion 45b of the inclined flange 45 and the other portion 52b of the inclined side wall 52 are in contact with each other.
Accordingly, both the inclined flange 45 and the inclined side wall 52 can be brought into contact over the entire area, and the inclined flange 45 and the inclined side wall 52 can be joined at the correct positions. Therefore, the assembly of the wheel house inner panel 41 and the wheel house outer panel 42 can be simplified.
As described above, according to the vehicle body structure 10 of the embodiment, as shown in fig. 3 and 4, the wheel house inner panel 41 and the wheel house outer panel 42 are formed in the U-shaped cross section, respectively. The enlarged portion 44 and the inclined flange 45 are formed on the wheel house inner panel 41, and the inclined side wall 52 is formed on the wheel house outer panel 42. The inclined flange 45 of the wheel house inner panel 41 is joined to the inclined side wall 52 of the wheel house outer panel 42 by so-called "shear mating".
Here, for example, a load due to vibration in the vehicle width direction is input to the rear wheel house 14 from a suspension (not shown) during traveling of the vehicle. Thereby, the load is input in the joining direction of the inclined flange 45 and the inclined side wall 52. That is, the inclined flange 45 and the inclined side wall 52 are joined in the direction of receiving the shear load.
Thus, the inclined flange 45 and the inclined side wall 52 can be firmly joined without using, for example, a reinforcing member, so that the inclined flange 45 and the inclined side wall 52 can be prevented from being peeled off by a load input by vibration in the vehicle width direction. Therefore, the vehicle body can be reduced in weight, and the strength and rigidity of the vehicle body can be improved.
Further, an inner ridge portion 46 is formed at an intersection of the inclined flange 45 and the expanded portion 44 of the wheel house inner panel 41. A reinforcing flange 53 is formed on the wheel house outer panel 42, and the reinforcing flange 53 projects outward of the rear wheel house 14 in a direction away from the inner ridge line portion 46 at a portion corresponding to the inner ridge line portion 46. As a result, the inclined side wall 52 is reinforced by the reinforcing flange 53, and the inclined side wall 52 can be firmly joined to the inclined flange 45. This makes it possible to easily improve the strength and rigidity of the vehicle body with a simple structure.
As shown in fig. 6, an outer ridge portion 54 is formed at an intersection of the inclined side wall 52 and the reinforcing flange 53 of the wheel house outer panel 42. The outer ridge line portion 54 is disposed at a position overlapping the inner ridge line portion 46 in the joining direction (i.e., the vehicle width direction) of the wheel house inner panel 41 and the wheel house outer panel 42. Thus, for example, the vibration in the vehicle width direction received (input) during traveling of the vehicle can be suppressed at both the outer edge line portion 54 and the inner edge line portion 46, and the strength and rigidity of the vehicle body can be improved.
As shown in fig. 5, the inclined flange 45 is provided over the entire circumference of the rear wheel house 14. This enables the inclined flange 45 to be joined to the inclined side wall 52 over the entire circumference of the rear wheel house 14. Thus, for example, when vibration in the vehicle width direction is input from the suspension during traveling of the vehicle, the vibration of the rear wheel house 14 can be suppressed by the joint portion of the inclined flange 45 and the inclined side wall 52, and the strength and rigidity of the vehicle body can be improved.
As shown in fig. 1 and 7, the left and right corner plates 61, 61 of the upper cross member 33 are connected to the left and right rear wheel houses 14, 14.
Here, the left end portion 61a of the left gusset 61 is overlapped on the upper portion 14b of the left rear wheel house 14 in a state of being sandwiched by the inclined flange 45 and the inclined side wall 52, and the overlapped three members are joined. Thereby, the left gusset 61 of the upper cross member 33 is firmly joined to the inclined flange 45 and the inclined side wall 52. The left rear wheel house 14 is joined by, for example, shear mating the inclined flange 45 and the inclined side wall 52.
Further, the right end portion 61a of the right gusset 61 is joined to the upper portion 14b of the right rear wheel house 14, similarly to the left end portion 61a of the left gusset 61.
This improves the strength and rigidity of the left and right rear wheel houses 14, 14 against vibration in the vehicle width direction. As a result, the upper portions 14b, 14b of the left and right rear wheel houses 14, 14 can be firmly coupled by the upper cross member 33, and the strength and rigidity of the vehicle body can be further improved.
The technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
For example, in the above-described embodiment, the example in which the expanded portion 44, the inclined flange 45, and the like are formed in the wheel house inner panel 41, and the inclined side wall 52, the reinforcing flange 53, and the like are formed in the wheel house outer panel 42 has been described, but the present invention is not limited thereto. As another example, the enlarged portion 44 and the inclined flange 45 may be formed on the wheel house outer panel 42, and the inclined side wall 52 and the reinforcing flange 53 may be formed on the wheel house inner panel 41.
In the above embodiment, the example has been described in which the present invention is applied to the rear wheel house 14, but the present invention is not limited to this. As another example, the present invention may be applied to the rocker 17 as shown in fig. 10.
Since the rocker 17 is formed substantially vertically symmetrically, the same reference numerals are assigned to the upper and lower portions, and only the upper portion will be described, and the description of the lower portion will be omitted.
That is, the rocker 17 includes a rocker inner panel (one of the first member and the second member, the inner member) 71 and a rocker outer panel (the other of the first member and the second member, the outer member) 72. The rocker inner panel 71 has an expanded portion 74, an inclined flange 75, and an inner ridge portion (ridge portion) 76 in the upper wall portion 71 a. The rocker outer panel 72 has an inclined side wall 81, a reinforcing flange 82, and an outer ridge portion (other ridge portion) 83 in the upper wall portion 72 a.
The inclined flange 75 of the rocker inner panel 71 is joined to the inclined side wall 81 of the rocker outer panel 72 in a fitted state.
Here, for example, during traveling of the vehicle, a load due to vibration in the vehicle width direction is input to the rocker 17. That is, the load is input in the joining direction of the inclined flange 75 and the inclined side wall 81. Thereby, the inclined flange 75 and the inclined side wall 81 are joined by so-called "shear mating" in the direction receiving the shear load.
Thus, the inclined flange 75 and the inclined side wall 81 can be firmly joined without using, for example, a reinforcing member, so that the inclined flange 75 and the inclined side wall 81 are prevented from being peeled off by a load input by vibration in the vehicle width direction. Therefore, the vehicle body can be reduced in weight, and the strength and rigidity of the vehicle body can be improved.
Further, when the rocker inner panel 71 and the rocker outer panel 72 are assembled, for example, the inclined flange 75 of the upper wall portion 71a and the inclined side wall 81 of the upper wall portion 72a serve as guides. This allows the lower wall portion 71b and the inclined side wall 81 of the lower wall portion 72b to be positioned so as to approach each other in the direction in which they contact each other.
This enables the inclined flange 75 of the upper wall portion 71a and the inclined side wall 81 of the upper wall portion 72a to be joined at the correct positions, and enables the inclined flange 75 of the lower wall portion 71b and the inclined side wall 81 of the lower wall portion 72b to be joined at the correct positions. Therefore, the assembly of the rocker inner panel 71 and the rocker outer panel 72 can be simplified.
Further, the present invention may be applied to the cowl structure 18 as shown in fig. 11. The cowl structure 18 includes a dash panel (the other of the first member and the second member, the outer member) 91, an dash panel upper panel (the one of the first member and the second member, the inner member) 92, and a windshield lower support 93. The dash upper panel 92 has an inclined flange 95. The dash lower panel 91 has inclined side walls 96, a reinforcing flange 97, and an outer ridge portion (other ridge portion) 98.
The inclined flange 95 of the dash upper panel 92 is joined to the inclined side wall 96 of the dash lower panel 91.
Here, for example, during traveling of the vehicle, a load generated by vibration in the vertical direction is input to the front surrounding structure 18. That is, the load is input in the joining direction of the inclined flange 95 and the inclined side wall 96. Thereby, the inclined flange 95 and the inclined side wall 96 are joined by so-called "shear mating" in the direction receiving the shear load.
This enables the inclined flange 95 and the inclined side wall 96 to be firmly joined without using, for example, a reinforcing member, so that the inclined flange 95 and the inclined side wall 96 can be prevented from being peeled off by a load input by vertical vibration. Therefore, the vehicle body can be reduced in weight, and the strength and rigidity of the vehicle body can be improved.
When the instrument panel upper plate 92 and the instrument panel lower plate 91 are assembled, for example, the inclined side wall 96 of the instrument panel lower plate 91 serves as a guide. This enables the inclined flange 95 of the dash upper panel 92 to be joined at a correct position. This can simplify assembly of the instrument panel upper panel 92 and the instrument panel lower panel 91.
In addition, the components in the above embodiments may be replaced with known components as appropriate without departing from the scope of the present invention, and the above modifications may be combined as appropriate.
