Description

Vehicle body front structure

Technical Field

The present invention relates to a vehicle body front structure.

This application claims priority based on Japanese patent application No. 2016-.

Background

As a vehicle body front portion structure, a structure is known in which a brake pedal (hereinafter, referred to as a pedal assembly) is twisted by an impact load input from a vehicle body front side, and a mounting bracket is deformed to interfere with the pedal assembly. By twisting the pedal assembly and deforming the mounting bracket to interfere with the pedal assembly, movement of the pedal portion toward the rear of the vehicle body can be suppressed.

By suppressing the movement of the step portion toward the rear of the vehicle body, when an impact load is input from the front of the vehicle body, it is possible to avoid interference between the foot of the passenger and the step (see, for example, patent document 1).

Problems to be solved by the invention

However, in the vehicle body front portion structure of patent document 1, in order to avoid interference between the feet of the passenger and the pedal portion, it is necessary to twist the pedal assembly and deform the mounting bracket. Therefore, the structure of the vehicle body front portion structure becomes complicated, and there is room for improvement from this viewpoint.

The present invention has been made in view of such circumstances, and an object thereof is to provide a vehicle body front structure that can avoid interference between a passenger's foot and a step portion with a simple configuration.

Means for solving the problems

In order to solve the above problems, the present invention adopts the following aspects.

(1) A vehicle body front structure according to an aspect of the present invention includes: a cowl lower panel that partitions a vehicle compartment from an engine compartment; a floor tunnel extending from the cowl lower panel toward a rear of a vehicle body; a pedal assembly that is located on a vehicle-width-direction outer side of the floor tunnel and has a mounting bracket mounted to the cowl top panel; and a reinforcement member that has an end portion overlapping with the mounting bracket and is mounted to the cowl lower panel from the engine compartment side, the cowl lower panel having: a vertical wall to which the mounting bracket is attached, a vertical corner portion being formed at an intersection of the vertical wall and the floor tunnel; and an inclined wall extending from the vertical wall toward the cabin side, and having a lateral corner portion formed at an intersection of the inclined wall and the vertical wall, wherein the reinforcing member has a corner portion provided along the vertical corner portion and the lateral corner portion and bent in an L-shape.

Thus, the corner portions of the reinforcing member are provided at the longitudinal corner portion and the lateral corner portion. Thus, when the power unit (e.g., transmission) of the engine room is moved rearward of the vehicle body and pressed against the dash lower panel, the reinforcement member can be deformed so as to fall down rearward of the vehicle body around the corner portion. This enables the end portion of the reinforcing member to move toward the rear of the vehicle body.

Further, the end of the reinforcing member is mounted so as to overlap the mounting bracket. This enables the mounting bracket to move toward the rear of the vehicle body together with the end portion of the reinforcement member. By moving the mounting bracket rearward of the vehicle body, the step portion of the step assembly can be moved forward of the vehicle body. Thus, the step portion can be separated from the passenger's foot, and the passenger's foot can be prevented from interfering with the step portion.

Further, interference between the passenger's foot and the pedal portion can be avoided by a simple structure in which the end portion of the reinforcement member is overlapped with the mounting bracket and the reinforcement member is provided with a corner portion.

(2) In the aspect (1), the vehicle body front portion structure may further include a cowl cross member provided to the vertical wall so as to overlap the one end portion of the reinforcement member, and the attachment bracket may include an upper fixing portion attached to the cowl cross member and a lower fixing portion located below the cowl cross member.

In this way, the cowl cross member is disposed so as to overlap with the end portion of the reinforcement member. The upper fixing portion is attached to the front cross member, and the lower fixing portion is disposed below the front cross member. Here, the reinforcement member and the cowl cross member have higher strength than the cowl lower panel.

Thus, when the power unit moves rearward of the vehicle body and is pressed against the dash lower panel, the upper fixing portion can be moved rearward of the vehicle body relative to the lower fixing portion together with the reinforcement member and the dash cross-member.

This allows the step portion to move toward the front of the vehicle body. Therefore, the step portion can be more favorably separated from the feet of the passenger.

(3) In the aspect (1), the reinforcement member may be formed in a top hat shape in cross section by a bottom portion, an inner wall, an outer wall, an inner flange, and an outer flange, and the inner flange and the outer flange may be attached to the cowl panel.

In this way, the reinforcing member is formed in a hat-shaped cross section and attached to the cowl bottom panel, whereby a closed cross section can be formed by the reinforcing member and the cowl bottom panel. This can improve the strength and rigidity of the reinforcing member.

Further, the inner flange of the reinforcement member can be extended from the vertical wall to the floor tunnel across the vertical corner portion. Further, the inner flange can be extended from the vertical wall to the inclined wall across the lateral corner portion. Thus, the vertical wall and the floor tunnel can be firmly connected, and the vertical wall and the lateral corner portion can be firmly connected.

(4) In the aspect of (2) above, the vehicle body front portion structure may further include a cowl cross member provided to the cowl bottom panel below the cowl cross member, the one end portion of the reinforcement member may overlap the cowl cross member, and another end portion of the reinforcement member below the one end portion may overlap the cowl cross member.

Thus, the end portion of the reinforcement member is overlapped with the cowl cross member, and the lower end portion of the reinforcement member is overlapped with the cowl cross member. Thus, when the power unit is moved rearward of the vehicle body and pressed against the dash lower panel, the end portion of the reinforcement member can be moved rearward of the vehicle body about the lower end portion of the reinforcement member.

This enables the step portion to be moved well toward the front of the vehicle body.

(5) In the aspect (1), the vehicle body front portion structure may further include a plug member provided at a steering shaft opening portion of the cowl top panel, and the reinforcing member may be formed to be curved along the plug member.

In this way, the reinforcing member is formed to be bent along the plugging member. This allows the position of the end of the reinforcing member to be relatively freely selected. The mounting bracket of the pedal assembly overlaps the end of the reinforcement member. This allows the mounting position of the mounting bracket to be selected relatively freely. Therefore, the pedal assembly can be mounted at an optimum position.

(6) In the aspect (1) described above, the cowl bottom panel may have a bead portion that faces the reinforcement member.

Thus, the cowl lower panel can be reinforced along the reinforcing member by the bead portion. Thus, when the power unit is moved rearward of the vehicle body and pressed against the dash lower panel, the end portion of the reinforcement member can be moved rearward of the vehicle body satisfactorily. Therefore, the step portion can be moved more favorably toward the front of the vehicle body.

(7) In the aspect (5) described above, the opposite side of the corner portion of the reinforcement member may overlap the blocking member and be fixed to the cowl lower panel together with the blocking member.

This enables the opposite side of the corner portion to be firmly fixed to the dash lower panel. Thus, when the power unit is moved rearward of the vehicle body and pressed against the dash lower panel, the reinforcement member can be deformed well so as to fall down rearward of the vehicle body around the corner portion.

(8) In the aspect (2) described above, the cowl cross member may include an extension portion that extends downward and is provided to the cowl lower panel, and the lower fixing portion may be attached to the extension portion.

In this way, the extension portion is extended downward from the cowl cross member, and the extension portion is provided to the cowl lower panel. The lower fixing portion is attached to the extension portion. The cowl cross member is higher in strength than the cowl lower panel.

Thus, when the power unit moves rearward of the vehicle body and is pressed against the dash lower panel, the upper fixing portion can be moved rearward of the vehicle body relative to the lower fixing portion together with the reinforcement member and the dash cross-member. This enables the step portion to be moved well toward the front of the vehicle body.

(9) In the aspect (4), the vehicle body front portion structure may further include a stopper that receives a pedal portion of the pedal assembly, and the stopper may be attached to the cowl bottom panel so as to straddle the cowl cross member.

Thus, the stopper is attached to the cowl lower panel so as to straddle the cowl cross member. Thus, the stopper can be separated from the lower cowl cross member. Thus, when the power unit is pressed against the cowl lower panel and the cowl cross member moves toward the rear of the vehicle body, the stopper can be prevented from retreating so as to approach the feet (i.e., the pedal portion) of the passenger.

Therefore, the step portion can be moved well toward the front of the vehicle body.

Effects of the invention

According to an aspect of the present invention, the corner portions of the reinforcing member are provided at the longitudinal corner portion and the lateral corner portion. Further, the end portion of the reinforcement member is mounted so as to overlap with the mounting bracket of the pedal assembly. Thus, when the power unit of the engine room is pressed against the dash lower panel, the end portion of the reinforcement member can be moved toward the rear of the vehicle body about the corner portion. Thus, the step portion can be separated from the passenger's foot, and the passenger's foot can be prevented from interfering with the step portion.

Detailed Description

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, arrow FR indicates the front of the vehicle, arrow UP indicates the upper side of the vehicle, and arrow LH indicates the left side of the vehicle.

As shown in fig. 1, the vehicle body front portion structure 10 includes a cowl lower panel 12, a floor tunnel 13, a cowl cross member 14, a cowl cross member 15, a pedal assembly 16, a reinforcing member 18 (see also fig. 4), a stopper 21, and a blocking member 22.

The dash lower panel 12 is disposed between the left and right front pillars and extends in the vehicle width direction. The dash lower panel 12 partitions the vehicle compartment 24 from the engine compartment 25. The dash lower panel 12 includes a vertical wall 27 that rises substantially vertically and an inclined wall 28 connected to a lower end portion 27a of the vertical wall 27. The inclined wall 28 extends in a downward gradient from the lower end portion 27a of the vertical wall 27 toward the cabin 24 (see also fig. 3).

The cowl lower 12 has a bead portion 29 bulging toward the vehicle cabin 24. The bead portion 29 extends downward from the upper cowl cross member 14 to the lower cowl cross member 15. Specifically, the upper end portion 29a of the bead portion 29 is connected to the cowl cross member 14. Further, the lower end portion 29b of the bead portion 29 extends to the vicinity of the cowl cross member 15.

The bead 29 is disposed between the floor tunnel 13 and the pedal assembly 16 in the vehicle width direction. The bead 29 is formed so as to face the reinforcing member 18 (see also fig. 5).

The floor tunnel 13 extends rearward of the vehicle body from the center of the lower portion of the vertical wall 27 and the center of the inclined wall 28. A floor is provided on the left side in the vehicle width direction and the right side in the vehicle width direction of the floor tunnel 13. The floor forms a floor portion of the vehicle compartment 24.

The left and

right beams

31, 32 extend upward from the front upper end 13a of the floor tunnel 13 along the vertical wall 27.

A vertical corner portion 34 (see fig. 6) is formed at the intersection of the front left portion 13b of the floor tunnel 13 and the vertical wall 27. Further, a lateral corner portion 35 (see fig. 6) is formed at the intersection of the lower end portion 27a of the vertical wall 27 and the distal end portion 28a of the inclined wall 28.

The longitudinal corner portion 34 and the lateral corner portion 35 will be described in detail later.

As shown in fig. 2 and 3, the cowl cross member 14 extends along the vertical wall 27 from the left side member 31 to the left front pillar toward the vehicle width direction outer side. The upper cowl cross member 14 is formed in a top hat shape in cross section by a rear portion 41, an upper portion 42, a lower portion 43, an upper flange 44, and a lower flange 45. The upper flange 44 and the lower flange 45 are joined to the vertical wall 27, whereby a closed cross section is formed by the upper cowl cross member 14 and the vertical wall 27.

The cowl cross member 14 has an extension portion 47 at a mounting portion 14a where the pedal assembly 16 is disposed. Specifically, the extension portion 47 extends downward from the lower flange 45 at the mounting portion 14 a. The extension portion 47 is disposed substantially coplanar with the rear portion 41 with a space from the vertical wall 27 toward the rear of the vehicle body. The lower end 47a of the extension 47 is joined to the vertical wall 27.

A lower cowl cross member 15 is provided below the cowl cross member 14 (i.e., the inclined wall 28). The lower cowl cross member 15 extends from the floor tunnel 13 toward the vehicle width direction outer side to the left front pillar. Specifically, the lower cowl cross member 15 is formed in a V-shape in cross section by the upper portion 51, the lower portion 52, the upper flange 53, and the lower flange 54. By joining the upper flange 53 and the lower flange 54 to the inclined wall 28, a closed cross section is formed by the cowl cross member 15 and the inclined wall 28.

The pedal assembly 16 is mounted to the mounting portion 14a and the extension portion 47 of the cowl cross member 14. In this state, the pedal assembly 16 is positioned on the vehicle width direction outer side of the floor tunnel 13. The pedal assembly 16 is an accelerator pedal, and includes a mounting bracket 56, a pedal arm 57, and a pedal portion 58.

The upper end portion 57a of the pedal arm 57 is rotatably supported by the mounting bracket 56 via a support shaft 61. The mounting bracket 56 has an upper fixing portion 56a mounted to the cowl cross member 14 and a lower fixing portion 56b located below the cowl cross member 14.

The upper fixing portion 56a is attached to the attachment portion 14a of the cowl cross member 14 by a pair of bolts 63 and nuts 64. The lower fixing portion 56b is attached to the extension portion 47 by a bolt 65 and a nut 66. That is, the attachment bracket 56 is attached to the vertical wall 27 via the cowl cross member 14 and the extension portion 47.

Thus, the pedal assembly 16 is attached to the attachment portion 14a and the extension portion 47 of the cowl cross member 14 via the attachment bracket 56.

The pedal arm 57 extends downward from the mounting bracket 56 toward the cabin 24 side. A pedal portion 58 is fixed to a lower end portion 57b of the pedal arm 57.

As shown in fig. 4, a steering shaft opening 68 is formed in the front lower panel 12. The closing flange 71 of the closing member 22 is coupled to the steering shaft opening portion 68. The seal flange 71 is formed in an annular shape along the steering shaft opening portion 68.

Thereby, the steering shaft opening portion 68 is closed by the closing member 22. The blocking member 22 is located on the vehicle width direction outer side of the pedal assembly 16 (see fig. 1). The steering shaft passes through the through hole 72 of the blocking member 22.

The reinforcement member 18 is mounted to the dash lower panel 12 from the side of the engine room 25. Specifically, the reinforcing member 18 is formed in a top hat shape in cross section by the bottom portion 74, the inner wall 75, the outer wall 76, the inner flange 77, and the outer flange 78 (see also fig. 5).

As shown in fig. 5, the bottom portion 74 is disposed at a distance from the vertical wall 27 toward the front of the vehicle body. The inner wall 75 extends from the vehicle width direction inner end 74a of the bottom portion 74 toward the vertical wall 27.

The outer wall 76 extends from the vehicle width direction outer end 74b of the bottom portion 74 toward the vertical wall 27. The inner flange 77 projects from the rear end 75a of the inner wall 75 toward the vehicle width direction inner side along the dash lower panel 12. The outer flange 78 projects outward in the vehicle width direction along the dash lower panel 12 from the rear end 76a of the outer wall 76.

The inner flange 77 and the outer flange 78 are attached to the dash lower panel 12. Thereby, the closed cross section is formed by the reinforcement member 18 and the cowl lower panel 12. This improves the strength and rigidity of the reinforcing member 18.

As shown in fig. 4 and 6, the reinforcing member 18 includes a lower reinforcing portion 81 joined to the vertical corner portion 34, the horizontal corner portion 35, and the blocking flange 71 of the blocking member 22, and an upper reinforcing portion 82 extending upward from the lower reinforcing portion 81.

The longitudinal corner portion 34 is formed in a protruding angle shape at the intersection of the front left portion 13b of the floor tunnel 13 and the longitudinal wall 27 and extends in the vertical direction. The lateral corner portion 35 is formed at the intersection of the lower end portion 27a of the vertical wall 27 and the front end portion 28a of the inclined wall 28 and extends in the vehicle width direction.

The upper reinforcement portion 82 extends upward from the lower reinforcement portion 81 along the plugging member 22. That is, the upper reinforcing portion 82 is formed to be curved along the plugging member 22. This allows the location of the upper end portion 18a of the reinforcing member 18 to be relatively freely selected in the vehicle width direction.

As shown in fig. 7, the upper end portion 18a of the reinforcement member 18 overlaps the upper cowl cross member 14. The upper end portion 18a of the reinforcement member 18 overlaps the mounting bracket 56 of the pedal assembly 16 via the cowl cross member 14.

Thus, the mounting position P1 of the mounting bracket 56 can be selected relatively freely in the vehicle width direction, as with the upper end portion 18a of the reinforcement member 18.

By selecting the mounting position P1 of the mounting bracket 56 relatively freely in the vehicle width direction, the pedal portion 58 of the pedal assembly 16 is mounted at an optimum position. That is, the attachment position P1 (see also fig. 1) of the pedal portion 58 is disposed at a position spaced apart from the inner end portion 93a of the stopper 21 (specifically, the stopper portion 93) by a distance L1.

Thereby, the pedal portion 58 is disposed at an optimum position with respect to the stopper portion 93 of the stopper 21. That is, the step portion 58 is disposed at a position most suitable for the passenger to operate.

As shown in fig. 5 and 6, the lower reinforcing portion 81 has a corner portion 84, an opposite side joint portion 85, and a reinforcing lower portion 86. The corner portion 84 has a first corner portion 84a provided along the longitudinal corner portion 34 and a second corner portion 84b provided along the lateral corner portion 35.

Thereby, the corner portion 84 is formed in a state of being bent into an L shape at the first corner portion 84a and the second corner portion 84b.

Here, in order to form the first corner portion 84a, the inner flange 77 of the reinforcing member 18 greatly projects inward in the vehicle width direction at the lower reinforcing portion 81. Thus, the inner flange 77 of the lower reinforcing portion 81 extends from the vertical wall 27 to the front left portion 13b of the floor tunnel 13 across the vertical corner portion 34, and is bent in a V-shape in cross section at the first corner portion 84a. The first corner portion 84a extends in the up-down direction along the longitudinal corner portion 34.

In this state, the inner flange 77 is joined to the vertical wall 27 and the front left side portion 13b of the floor tunnel 13 by spot welding. Thereby, the vertical wall 27 and the floor tunnel 13 are firmly connected by the inner flange 77 of the lower reinforcement portion 81.

The reinforcing lower portion 86 extends from the vertical wall 27 to the inclined wall 28 across the lateral corner portion 35, and is bent in a V-shape in cross section at the second corner portion 84b. The second corner portion 84b extends in the vehicle width direction along the lateral corner portion 35.

In this state, the reinforcing lower portion 86 is joined to the vertical wall 27 and the inclined wall 28 by spot welding. Thus, the vertical wall 27 and the inclined wall 28 are firmly connected by the reinforcing lower portion 86 of the lower reinforcing portion 81.

Thus, the vertical wall 27 and the floor tunnel 13 are firmly joined by the inner flange 77, and the vertical wall 27 and the inclined wall 28 are firmly joined by the reinforcing lower portion 86.

Thereby, the corner portions 84 of the lower reinforcing portion 81 are firmly connected to the vertical corner portions 34 and the horizontal corner portions 35.

As shown in fig. 7, the upper end portion 18a of the reinforcement member 18 overlaps the attachment bracket 56 of the pedal assembly 16 via the cowl cross member 14.

As shown in fig. 4 and 8, a power unit (e.g., a transmission) 91 of the engine room 25 moves rearward of the vehicle body and is pressed against the dash lower panel 12. Thereby, the impact load F1 is input from the engine room 25 side to the reinforcement member 18.

In this state, the reinforcing member 18 can be deformed so as to fall down toward the vehicle body rear side as indicated by arrow a, centering around the corner portion 84 (specifically, the second corner portion 84 b). This enables the upper end portion 18a of the reinforcing member 18 to move toward the rear of the vehicle body.

Here, the upper end portion 18a of the reinforcement member 18 overlaps the mounting bracket 56 of the pedal assembly 16 with the cowl cross member 14 interposed therebetween. This allows the mounting bracket 56 to move toward the rear of the vehicle body as indicated by arrow a together with the upper end portion 18a of the reinforcement member 18. This allows the pedal portion 58 of the pedal unit 16 to move toward the front of the vehicle body as indicated by arrow B. Therefore, the step portion 58 can be separated from the passenger's foot, and interference between the passenger's foot and the step portion 58 can be avoided.

In this way, interference between the passenger's foot and the pedal portion 58 can be avoided by a simple configuration in which the reinforcement member 18 is provided with the corner portion 84 and the upper end portion 18a of the reinforcement member 18 is overlapped with the mounting bracket 56.

Returning to fig. 5 and 6, the opposite-side coupling portion 85 is located on the opposite side of the corner portion 84 (specifically, the first corner portion 84 a). The opposite-side coupling portion 85 overlaps the inner portion 71a of the closing flange 71 from the engine room 25 side. In this state, the opposite side joint portion 85 is joined to the dash lower panel 12 (particularly, the vertical wall 27) together with the inner portion 71a of the blocking flange 71.

Thereby, the opposite-side joint portion 85 (i.e., the opposite side of the first corner portion 84a) is firmly fixed to the dash lower panel 12.

As a result, as shown in fig. 8, when an impact load F1 is input from the power unit 91 to the reinforcing member 18, the upper end portion 18a of the reinforcing member 18 can be caused to fall down more favorably as indicated by arrow a around the second corner portion 84b. Therefore, the step portion 58 can be separated from the passenger's foot, and interference between the passenger's foot and the step portion 58 can be more favorably avoided.

The extension portion 47 extends downward from the attachment portion 14a of the cowl cross member 14, and a lower end portion 47a of the extension portion 47 is attached to the cowl lower panel 12. The upper fixing portion 56a is attached to the attachment portion 14a of the cowl cross member 14, and the lower fixing portion 56b is attached to the extension portion 47. Here, the reinforcement member 18 and the upper cowl cross member 14 are higher in strength than the cowl lower panel 12.

When an impact load F1 is input from the power unit 91 to the reinforcement member 18, the upper fixing portion 56a moves toward the rear of the vehicle body as indicated by arrow C together with the reinforcement member 18 and the cowl cross member 14 with respect to the lower fixing portion 56b. This enables the step portion 58 to be moved more favorably toward the front of the vehicle body, and thus interference between the passenger's foot and the step portion 58 can be more favorably avoided.

Returning to fig. 3, the lower end portion 18b of the lower reinforcing portion 81 is located below the upper end portion 18a. The lower end portion 18b of the lower reinforcement portion 81 overlaps the upper flange 53 of the lower cowl cross member 15 with the cowl lower panel 12 interposed therebetween.

Here, the lower end portion 18b of the lower reinforcing portion 81 is disposed in the vicinity of the second corner portion 84b. Further, the upper end portion 18a of the reinforcement member 18 overlaps the cowl cross member 14.

As a result, as shown in fig. 8, when an impact load F1 is input from the power unit 91 to the reinforcing member 18, the upper end portion 18a of the reinforcing member 18 can be lowered more favorably as indicated by arrow a around the lower end portion 18b of the lower reinforcing portion 81. Therefore, the step portion 58 can be separated from the passenger's foot, and interference between the passenger's foot and the step portion 58 can be more favorably avoided.

Returning to fig. 5, the reinforcement member 18 is disposed so as to face the bead portion 29 of the dash lower panel 12. Thereby, the cowl lower 12 is reinforced by the bead portion 29 along the reinforcement member 18.

As a result, as shown in fig. 8, when an impact load F1 is input from the power unit 91 to the reinforcing member 18, the upper end portion 18a of the reinforcing member 18 can be moved more favorably toward the vehicle body rear side as indicated by arrow a. Therefore, the step portion 58 can be separated from the passenger's foot, and interference between the passenger's foot and the step portion 58 can be more favorably avoided.

Returning again to fig. 3, a stopper 21 is provided so as to straddle the cowl cross member 15. The stopper 21 has a stopper portion 93, an upper leg portion 94, a lower leg portion 95, an upper joint portion 96, and a lower joint portion 97.

The stopper portion 93 is disposed at a space rearward of the vehicle body with respect to the lower portion 52 of the cowl cross member 15. The upper leg 94 extends from the upper end of the stopper 93 toward the front of the vehicle body to the inclined wall 28. The upper leg portion 94 is disposed above the upper portion 51 and the upper flange 53 of the lower cowl cross member 15.

The lower leg 95 extends from the lower end of the stopper 93 toward the front of the vehicle body to the inclined wall 28. The lower leg portion 95 is disposed below the lower flange 54 of the lower cowl cross member 15.

The upper joint 96 extends from the front end of the upper leg 94 along the inclined wall 28 in an upward gradient. The lower engaging portion 97 extends from the front end of the lower leg portion 95 along the inclined wall 28 in a downward gradient. The upper joint portion 96 and the lower joint portion 97 are joined to the inclined wall 28. Thus, the stopper 21 is attached to the inclined wall 28 so as to straddle the cowl cross member 15.

When the pedal portion 58 of the pedal unit 16 is depressed a predetermined distance in the arrow direction toward the front of the vehicle body, the pedal portion 58 is received by the stopper portion 93.

As shown in fig. 8, when an impact load F2 is input to the cowl cross member 15 from the power unit 91, the cowl cross member 15 moves toward the vehicle body rear side.

Here, the stopper 21 is disposed so as to straddle the cowl cross member 15 up and down, and is disposed apart from the cowl cross member 15.

This can prevent the stopper 21 from moving backward so as to approach the foot (i.e., the pedal portion 58) of the passenger. This can sufficiently ensure the amount of movement of the pedal portion 58 of the pedal assembly 16 toward the front of the vehicle body.

That is, when the pedal portion 58 moves toward the front of the vehicle body as indicated by arrow B due to the impact load F1 input from the power unit 91, the amount of movement of the pedal portion 58 in the direction indicated by arrow B can be sufficiently ensured. Therefore, the step portion 58 can be separated from the passenger's foot, and interference between the passenger's foot and the step portion 58 can be avoided.

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 embodiment, an accelerator pedal is exemplified as the pedal assembly, but not limited thereto. As another example, the pedal unit may be a pedal such as a brake pedal.

In the above embodiment, the example in which the end portion of the reinforcing member 18 is the upper end portion 18a is described, but the present invention is not limited thereto. The other portion may be an end portion of the reinforcing member 18.
