Abstract

PROBLEM TO BE SOLVED: To obtain a vehicle interior member that effectively prevents a desired pedal from being displaced backward.SOLUTION: When a brake pedal 49 in contact with an abutting part 48, while a clutch pedal 22 is in contact with a restriction part 20, presses the abutting part 48 with a predetermined force or more, stress is concentrated on a notch 86 set between the restriction part 20 and the abutting part 48 to cause a fracture, and, in addition, a fracture part 84 set behind the notch 86 is broken when the fracture generated in the notch 86 becomes larger. The fracture causes deformation on the abutting part 48 rather than the fracture part 84, thereby preventing deformation and displacement on the restriction part 20. Thus, the clutch pedal 22 can be properly supported by the restriction part 20, thereby preventing backward displacement of the clutch pedal 22.

Description

  The present invention relates to an interior member for a vehicle such as an under cover for a vehicle compartment provided on the lower side of an instrument panel in front of a driver seat or a passenger seat, for example.

  An interior material called an undercover or the like as disclosed in Patent Document 1 below may be provided below the instrument panel in front of the driver seat or the passenger seat, for example.

JP 2009-83828 A

  By the way, in the case of a driver's seat of a so-called “manual vehicle”, a clutch pedal is provided in front of the under cover. When the vehicle collides with an obstacle ahead and the vehicle body is deformed, the clutch pedal is displaced rearward together with the deformed vehicle body. If the above-mentioned under cover interferes with the clutch pedal that is displaced rearward in this way, the rearward displacement of the clutch pedal can be suppressed.

  However, a brake pedal is provided in front of the under cover in addition to the clutch pedal, and the brake pedal is also displaced rearward along with the deformed vehicle body. Since the brake pedal is structurally less displaced rearward than the clutch pedal, it is not necessary to suppress the rearward displacement of the brake pedal compared to the clutch pedal. However, when the brake pedal is displaced rearward and abuts against the under cover and presses the under cover, the portion of the under cover where the clutch pedal abuts may move, and the portion where the clutch pedal abuts moves. This makes it difficult to control the rearward displacement of the clutch pedal.

  An object of the present invention is to obtain an interior member for a vehicle that can effectively suppress a rearward displacement of a desired pedal in consideration of the above fact.

  The vehicle interior member according to the first aspect of the present invention includes at least one first pedal and at least one second pedal different from the first pedal, each of which is a vehicle occupant. An interior member body provided on the rear side of the plurality of pedals operated by stepping on and below the instrument panel of the vehicle, and so as to face the first pedal behind the first pedal. A regulating portion that is set in the interior member main body and that abuts against the first pedal when the first pedal is displaced rearward and suppresses rearward displacement of the first pedal; and A contact portion that is set on the interior member body on the rear side and contacts the second pedal when the second pedal is displaced rearward, and the second pedal contacts the contact portion. The abutting portion with the second Pedal is broken by stress concentration when the pressed, and a, and a stress concentration portion to generate at the abutment side of the regulation portion deformed by pressing from the second pedal.

  The vehicle interior member according to the first aspect of the present invention is provided on the rear side of a plurality of pedals in which the interior member main body is provided side by side in the vehicle width direction and below the instrument panel of the vehicle. The interior member body has a restriction portion and a contact portion, and the restriction portion is located behind the first pedal which is at least one of the plurality of pedals. An abutting portion is located behind the second pedal, which is at least one excluding the first pedal.

  When a load from the front of the vehicle is applied to the vehicle and thereby the vehicle body is deformed, the plurality of pedals may be displaced rearward along with the deformation. When such a displacement of the pedal occurs, the first pedal comes into contact with the restricting portion, and the restricting portion suppresses the rearward displacement of the first pedal.

  On the other hand, when the second pedal is displaced rearward along with the deformation of the vehicle body, the second pedal contacts the contact portion and presses the contact portion rearward. Here, the stress concentration part is set in the interior member main body, and when the second pedal presses the contact part backward, the stress based on the pressing force is concentrated on the stress concentration part, and the stress concentration part has the interior. Breakage occurs in the member body.

  When breakage occurs in the stress concentration portion in this way, deformation occurs on the contact portion side in the interior member body due to the pressing force from the second pedal. For this reason, when a break occurs at the stress concentration portion, the state where the restriction portion is attached to the instrument panel or the vehicle body at least partially separated from the contact portion side is maintained, and the break occurs at the stress concentration portion. After this, the displacement of the first pedal can be effectively suppressed.

  As described above, the vehicle interior member according to the present invention is configured so that when the vehicle body is deformed by a load from the front, the restriction portion is configured such that the pedal that is desired to suppress the rearward displacement is the first pedal. By setting the contact portion and the stress concentration portion, the backward displacement of the pedal can be effectively suppressed.

  In the present invention, examples of the pedal provided in front of the interior member body include a brake pedal, a clutch pedal, and an accelerator pedal. However, the pedal according to the present invention is not limited to its use and the like as long as the pedal is operated by being depressed. Therefore, the use of this pedal may be, for example, a parking brake pedal that operates the parking brake by depressing it.

  A vehicle interior member according to a second aspect of the present invention is the vehicle interior member according to the first aspect of the present invention, wherein the vehicle interior member is formed on a flat plate portion and at least a front end of the plate portion, and upward from the plate portion. The interior member main body is configured including the wall portion erected.

  In the vehicle interior member according to the second aspect of the present invention, the interior member main body has a flat plate portion, and the wall portion is erected from at least the front end portion of the plate portion. This increases the rigidity of the vehicle interior member.

  The vehicle interior member according to a third aspect of the present invention is the vehicle interior member according to the first or second aspect of the present invention, wherein the vehicle interior member is formed at a front end of the interior member main body on the contact portion side with respect to the restriction portion. The stress concentration portion includes a wedge-shaped notch whose opening width decreases toward the rear.

  In the interior member for a vehicle according to the third aspect of the present invention, the abutting portion with which the second pedal displaced backward is in contact with the regulating portion with which the first pedal displaced backward is brought into contact with the front end of the interior member main body. A notch-like notch is formed on this side. The notch is formed in a wedge shape whose opening width decreases toward the rear. For this reason, when the second pedal presses the contact portion backward, stress concentrates on the bottom portion of the notch (the portion located most rearward in the notch), and the interior member main body breaks. As the breakage generated at the bottom of the notch progresses in this way, the contact portion side of the interior member body is deformed by the pressure from the second pedal rather than the regulating portion.

  In the present invention according to claim 3, the notch may be formed at the front end of the interior member main body. Therefore, for example, when the present invention described in claim 3 is dependent on the present invention described in claim 2, the notch is formed only in the front end of the plate portion and the notch is not formed in the wall portion. Alternatively, the notch may be formed only on the wall portion and not on the plate portion. Furthermore, you may form a notch continuously from a wall part to a plate part.

  The vehicle interior member according to a fourth aspect of the present invention is the vehicle interior member according to the third aspect of the present invention, wherein the plate portion is positioned on the contact portion side with respect to the restricting portion and on the rear side with respect to the notch. And a breakage portion that is formed continuously or intermittently from the front end side to the rear end side of the interior member main body and that breaks when the breakage caused by the notch reaches.

  In the vehicle interior member according to the fourth aspect of the present invention, the fracture portion is formed closer to the contact portion than the restriction portion in the interior member body. The fracture portion is formed on the rear side of the notch, and the second pedal presses the contact portion to cause the fracture in the notch. When the fracture at the notch progresses, the fracture starts at the fracture portion, thereby The inner member main body is deformed on the contact portion side of the restricting portion.

  An interior member for a vehicle according to a fifth aspect of the present invention is the vehicle interior member according to the fourth aspect of the present invention, wherein the direction from the front end to the rear end of the fracture portion is changed from the predetermined portion of the second pedal to the notch. The vehicle is inclined at an acute angle toward the center in the vehicle width direction with respect to the direction toward.

  In the vehicle interior member according to the fifth aspect of the present invention, the direction from the front end to the rear end of the fracture portion is inclined at an acute angle with respect to the direction from the predetermined portion to the notch in the second pedal. For this reason, when breakage proceeds from the notch and breakage of the front end of the breakage portion starts, the pressing force from the second pedal applied to the support portion effectively contributes to breakage at the breakage portion, and the breakage portion Can be advanced from the front end to the rear end side.

  The vehicle interior member according to a sixth aspect of the present invention is the vehicle interior member according to the fourth or fifth aspect of the present invention, wherein the rear end of the fracture portion is positioned closer to the center in the vehicle width direction than the front end. The direction from the front end to the rear end of the fracture portion is inclined toward the center in the vehicle width direction with respect to the direction from the front to the rear of the vehicle.

  In the vehicle interior member according to the sixth aspect of the present invention, the direction from the front end to the rear end of the broken portion is from the front to the rear so that the rear end of the broken portion is located on the center side in the vehicle width direction from the front end. Inclined toward the center in the vehicle width direction. For this reason, even if the inclination of the direction of the pressing force applied from the second pedal to the abutting portion is small in the vehicle width direction or there is no inclination in the vehicle width direction, it is applied to the support portion. The pressing force from the second pedal effectively contributes to the fracture at the fracture portion, and the fracture at the fracture portion can be advanced from the front end to the rear end side.

  The vehicle interior member according to a seventh aspect of the present invention is the vehicle interior member according to any one of the fourth to sixth aspects, wherein the interior member main body is closer to the contact portion than the restriction portion. The rib is erected from the front end side to the rear end side, and the corner portion on the contact portion side at the base end portion of the rib is used as the fracture portion.

  In the interior member for a vehicle according to the seventh aspect of the present invention, a rib is erected from the front end side to the rear end side of the interior member main body on the contact portion side of the regulation member in the interior member main body, Further, the corner on the contact portion side at the base end portion of the rib is a broken portion. When breakage (cracking, etc.) caused in the notch progresses, the interior member body breaks along the rib at the corner on the abutment side at the base end of the rib, and the interior member on the abutment side of the rib Deformation occurs in the main body.

  In addition, even when a breakage occurs at the corner on the abutting portion side at the base end portion of the rib in this way, and the interior member main body is deformed on the abutting portion side with respect to the rib, the rib causes the regulating portion side from the rib Increased rigidity. Thereby, a deformation | transformation of the interior member main body by the side of a control part can be suppressed, and the movement of a control part (especially part which opposes a 1st pedal) can be suppressed. For this reason, the backward displacement of the first pedal can be effectively suppressed by the restricting portion.

  As described above, the vehicle interior member according to claim 1 is less affected by the restricting portion even when the rearwardly displaced second pedal comes into contact with the contact portion and presses the contact portion. The restricting portion can effectively suppress the rearward displacement of the first pedal.

  The vehicle interior member according to the second aspect of the present invention has a high rigidity because the interior member body includes the plate portion and the wall portion standing from at least the front end of the plate portion. it can.

  The vehicle interior member according to the third aspect of the present invention can be deformed by pressing by the second pedal on the contact portion side of the interior member main body with respect to the restricting portion, and the contact portion in the restricting portion is received. Further, the influence of the pressing force from the second pedal can be reduced.

  According to a fourth aspect of the present invention, the interior member for a vehicle according to the present invention can cause breakage due to the pressing force from the second pedal on the contact portion side with respect to the restricting portion in the interior member body. The deformation can be caused on the contact portion side with respect to the restriction portion.

  The vehicle interior member according to the fifth aspect of the present invention can effectively cause the pressing force from the second pedal to contribute to the breakage at the breakage portion, and the breakage occurring at the breakage portion can be efficiently performed on the front end side. It can be made to break up from the rear end side.

  In the vehicle interior member according to the sixth aspect of the present invention, there is little inclination in the vehicle width direction of the direction of the pressing force applied from the second pedal to the contact portion, or in the vehicle width direction. Even when there is no inclination, the pressing force from the second pedal can effectively contribute to the fracture at the fracture portion, and the fracture occurring at the fracture portion proceeds efficiently from the front end side to the rear end side. Can be made.

  The interior member for a vehicle according to the seventh aspect of the present invention can be broken on the contact portion side with respect to the rib, and can suppress deformation of the interior member main body on the regulating portion side with respect to the rib.

The third plate portion 46 has a dimension along the vehicle front-rear direction shorter than the first plate portion 14 and the second plate portion 44, and the first plate portion 14 and the second plate portion 44 are behind the vehicle front-rear direction intermediate portion. It is connected by the third plate part 46 on the side.

  For this reason, the first plate portion 14 and the second plate portion 44 are separated in the vehicle width direction on the front side of the third plate portion 46. The front end of the third plate portion 46 is a contact portion 48. Between the first plate portion 14 and the second plate portion 44 on the front side of the contact portion 48, the “plural pedals” of the present invention. Among them, a brake pedal 49 as a “second pedal” is provided, and the brake pedal 49 and the contact portion 48 face each other in the front-rear direction of the vehicle.

  In addition, a bulging portion 50 is formed in the second plate portion 44. The bulging portion 50 bulges upward and curves so as to open downward, and is formed along the outer peripheral portion of the second plate portion 44. Further, a slope portion 52 is continuously formed from the rear end portion of the second plate portion 44. The slope portion 52 is a slope whose rear end is positioned below the front end where at least the upper surface is connected to the second plate portion 44. A plate portion 54 is continuously formed from the rear end of the slope portion 52.

  A peripheral wall 58 as a wall portion is erected upward on the outer peripheral portion of the first cover main body 12 and the second cover main body 42 that are integrally connected to each other by the third plate portion 46. The peripheral wall 58 is formed so as to protrude upward in a direction (vertical direction) intersecting the plate portions such as the first plate portion 14 and the second plate portion 44. A mounting portion 62 is formed on the peripheral wall 58 on the rear end side of the first cover body 12. A through-hole 64 penetrating in the front-rear direction is formed in the mounting portion 62, and a bolt (not shown) that passes through the through-hole 64 is a through-hole in a mounting portion (not shown) formed in the instrument panel 66 shown in FIG. When the nut passes through and the nut is screwed together, the mounting portion 62, and hence the under cover 10, is fixed to the instrument panel 66.

  Further, as shown in FIGS. 1 and 2, a mounting portion 68 is formed on the first plate portion 14 in the vicinity of the peripheral wall 58 on the rear side of the restricting portion 20 described above. A through hole 70 penetrating in the front-rear direction is formed in the mounting portion 68, and a bolt (not shown) that passes through the through hole 70 passes through a through hole of the mounting portion (not shown) formed in the instrument panel 66 shown in FIG. When the nut passes and is screwed together, the attachment portion 68, and hence the under cover 10, is fixed to the instrument panel 66.

  On the other hand, as shown in FIGS. 1 and 2, a mounting portion 72 is formed on the peripheral wall 58 on the rear end side of the second cover main body 42. A through hole 74 penetrating in the front-rear direction is formed in the mounting portion 72, and a bolt (not shown) that passes through the through hole 74 passes through a through hole of the mounting portion (not shown) formed in the instrument panel 66 shown in FIG. When the nut passes and is screwed together, the mounting portion 72, and thus the under cover 10, is fixed to the instrument panel 66 and covers the column of the steering device from below.

  As shown in FIGS. 1 and 2, a plurality of ribs 76 each extending substantially in the vehicle front-rear direction are provided between the peripheral wall 58 and the switch mounting portion 18 in the restricting portion 20. The mechanical strength with respect to the load from the front in 20 is supplemented. Further, as shown in FIGS. 1 and 6, ribs 82 stand up from the outer end of the third plate portion 46 in the vehicle width direction (that is, the boundary portion between the third plate portion 46 and the first plate portion 14). It is installed. The rib 82 is formed in a narrow plate shape whose width direction extends in the vertical direction, and as shown in FIG. 2, the longitudinal direction is such that the rear end is located closer to the center side in the vehicle width direction than the front end. Therefore, the rib 82 is arranged along the direction inclined in the vehicle width direction with respect to the vehicle longitudinal direction.

  A corner portion on the third plate portion 46 side at the base end portion of the rib 82 is a broken portion 84. As shown in FIGS. 1 and 3 and more specifically in FIG. 5, a notch 86 as a stress concentration portion is set in the second plate portion 44 in front of the fracture portion 84. The notch 86 is a wedge-shaped notch that opens substantially forward at the end of the second plate portion 44 on the vehicle front side. Further, the notch 86 is continuously formed up to the upper end portion of the peripheral wall 58 (in other words, the notch 86 is formed in both the second plate portion 44 and the peripheral wall 58).

  Further, the notch 86 is located on the vehicle rear side with respect to the pedal arm 49A of the brake pedal 49 described above and on the outer side in the vehicle width direction (that is, the direction tilted outward in the vehicle width direction with respect to the vehicle rear). Is formed. In addition, the direction from the front end to the rear end of the fracture portion 84 with respect to the direction from the center of the pedal arm 49A to the notch 86 in the plan view (direction from the vehicle front side to the rear side in the alternate long and short dash line A in FIG. 2). The formation positions of the ribs 82 and the notches 86 are set so that the angle θ formed by is an acute angle.

  By forming such a notch 86, the thickness of the peripheral wall 58 becomes thinner at the bottom of the notch 86 (the end of the notch 86 on the vehicle rear side) than other portions of the peripheral wall 58. For this reason, the mechanical strength of the peripheral wall 58 is weaker than other parts of the peripheral wall 58 at the bottom of the notch 86, and stress tends to concentrate.

<Operation and effect of the present embodiment>
Next, the operation and effect of the present embodiment will be described.

  For example, when the vehicle collides with an obstacle on the front side of the vehicle width direction center of the vehicle and the vehicle body is deformed by a load from the front due to this, the clutch pedal 22 whose upper end side is connected to the vehicle body is deformed. The vehicle body and the vehicle body are displaced in a direction inclined outward in the vehicle width direction with respect to the vehicle rear (hereinafter, this direction is referred to as “vehicle outer rear” for convenience). Here, the restricting portion 20 of the under cover 10 faces the clutch pedal 22 on the rear side of the clutch pedal 22.

  Therefore, as shown in FIG. 3, the restricting portion 20 abuts on and interferes with the clutch pedal 22 displaced rearward of the vehicle. In this state, when the clutch pedal 22 further presses the restricting portion 20 in an attempt to displace to the rear side of the vehicle, the clutch pedal 22 rotates forward around the connecting portion with the vehicle body on the upper end side by the pressing reaction force from the restricting portion 20. (I.e., a state similar to a state where the clutch pedal 22 is depressed by an occupant). Thereby, the displacement of the clutch pedal 22 to the rear side outside the vehicle is restricted.

  On the other hand, when the vehicle body is deformed by the load from the front as described above, the brake pedal 49 whose upper end is connected to the vehicle body is also displaced rearward of the vehicle together with the deformed vehicle body. However, in general, the brake pedal 49 is displaced rearwardly outside the vehicle as compared with the clutch pedal 22 even when the vehicle body is deformed as described above due to the connection structure with the vehicle body or the structure of the brake pedal 49 itself. The amount is small. However, the brake pedal 49 is also displaced rearward although it is smaller than the clutch pedal 22, and as shown in FIG. 3, it abuts against the abutting portion 48 of the under cover 10 located behind the brake pedal 49. .

  When the brake pedal 49 further presses the abutting portion 48 toward the vehicle outer rear side in a state where the brake pedal 49 abuts on the abutting portion 48, a portion of the rib 82 in the vicinity of the abutting portion 48 is partially pressed. In particular, stress concentrates on the bottom (corner) of the notch 86 where the rib 82 is thin. Thus, when stress concentrates on the rib 82 at the bottom of the notch 86, the rib 82 breaks at the bottom of the notch 86.

  As described above, since the notch 86 is formed so as to be aligned in the front-rear direction with respect to the front end of the breakage portion 84, when a crack (one aspect of breakage) generated in the notch 86 proceeds, the base end portion of the rib 82 The crack reaches the vicinity of the front end of the breakage portion 84, which is the corner on the second cover main body 42 side. When the crack reaches the vicinity of the front end of the fracture portion 84 in this way, the crack progresses from the front end side to the rear end side of the fracture portion 84, and as shown in FIG. A portion on the rear side of 48, that is, the third plate portion 46 is deformed.

  As described above, when the pressing force from the brake pedal 49 is applied to the contact portion 48, a crack is generated at the breaking portion 84, and the third plate portion 46 on the side opposite to the regulating portion 20 via the breaking portion 84. (That is, the second cover main body 42) is deformed, so that the first cover main body 12 side where the restricting portion 20 is set is less affected by the pressing force from the brake pedal 49 received by the contact portion 48, and the contact Even if the portion 48 is pressed by the brake pedal 49, the first cover body 12 does not displace, or the displacement of the first cover body 12 due to the contact portion 48 being pressed by the brake pedal 49 is small. Thereby, the regulation part 20 set to the 1st cover main body 12 can interfere appropriately with respect to the clutch pedal 22, and can regulate the displacement to the vehicle outer back of the clutch pedal 22. FIG.

  Here, in the under cover 10, as described above, the notch 86 is provided at the front end of the boundary portion between the first cover body 12 in which the restricting portion 20 is set and the second cover body 42 in which the contact portion 48 is set. It is set. For this reason, stress is concentrated on the boundary portion between the first cover main body 12 and the second cover main body 42 by the pressing force applied from the brake pedal 49 to the contact portion 48 to generate a crack which is one mode of fracture. Can do. In addition, since the fracture portion 84 is set behind the notch 86, when the fracture caused by the notch 86 proceeds, the fracture portion 84 is continuously cracked and deformed on the second cover body 42 side with respect to the fracture portion 84. Can be generated.

  Further, the breaking portion 84 has a rear end side inclined more toward the vehicle width direction center side than the front end side, and the front end of the breaking portion 84 with respect to the direction of the pressing force applied from the brake pedal 49 to the contact portion 48. The direction from to the rear end is inclined at an acute angle. Thereby, after the breakage generated at the notch 86 proceeds to the vicinity of the front end of the breakage portion 84, the breakage portion 84 is broken from the front end side without any pressing force (load) from the brake pedal 49.

  In addition, the breaking portion 84 is a corner portion on the second cover main body 42 side at the proximal end portion of the rib 82. For this reason, even if a fracture occurs in the fracture portion 84 and deformation occurs on the second cover main body 42 side, rigidity is compensated for by the rib 82 on the first cover main body 12 side, and the contact portion 48 is received from the brake pedal 49. The shape of the first cover body 12 can be maintained, and the displacement of the first cover body 12 can be effectively suppressed.

  Thereby, the displacement to the vehicle outer back of the clutch pedal 22 by the control part 20 interfering with the clutch pedal 22 can be controlled effectively.

  In the above description, the direction of the pressing force applied to the contact portion 48 by the brake pedal 49 has been described as the rear side outside the vehicle (the direction tilted outward in the vehicle width direction with respect to the rear side of the vehicle). There is also a possibility that the direction of the vehicle is rearward of the vehicle without being inclined in the vehicle width direction. Here, as described above, the direction from the front end to the rear end of the fracture portion 84 is inclined toward the center in the vehicle width direction with respect to the rear of the vehicle. For this reason, even if the direction of the above-mentioned pressing force is not inclined in the vehicle width direction but behind the vehicle, the direction from the front end to the rear end of the fracture portion 84 is inclined at an acute angle with respect to the direction of the pressing force. Therefore, even when such a pressing force is applied to the contact portion 48, the same effect as described above can be obtained.

  In the present embodiment, the present invention is applied to the under cover 10 for a left-hand drive vehicle. However, the under cover for a so-called right-hand drive vehicle in which the driver's seat is on the right side of the passenger seat or for vehicles other than the under cover. You may apply this invention to an interior member.

  In the present embodiment, a rib 82 is formed at the boundary between the first cover main body 12 and the second cover main body 42, and the corner on the second cover main body 42 side at the base end portion of the rib 82 is a broken portion. 84. However, the aspect of the “breaking portion” referred to in the claims is not limited to such an aspect. For example, as shown in FIG. 8, the rib 82 is not formed at the boundary portion between the first cover body 12 and the second cover body 42, and the boundary portion between the first cover body 12 and the second cover body 42 is formed. A notch 94 may be formed as a “breaking portion”. In such a configuration, when a crack that has progressed from the notch 86 progresses to the notch 94, a crack (break) that occurs in the fracture portion 84 also occurs in the notch 94.

  Further, in the present embodiment, the fracture portion 84 is configured to be continuous from the front end to the rear end. For example, as described above, the boundary portion between the first cover main body 12 and the second cover main body 42 is thin. As long as the “breaking portion” is formed, the “breaking portion” may be intermittently formed in a dotted line without forming the “breaking portion” in a continuous linear shape.

  Further, in the present embodiment, the “first pedal” is the clutch pedal 22 and the “second pedal” is the brake pedal 49, but the “first pedal” or the “second pedal” is used. ”Is not limited to the clutch pedal 22 or the brake pedal 49, as long as the pedal is provided in front of the feet of the driver's seat and passenger seat, regardless of its function or use, Recognized as “multiple pedals” including “two pedals”.

  For example, the so-called “automatic vehicle” is not provided with the clutch pedal 22, but there is a vehicle type provided with a parking brake pedal that can operate the parking brake by depressing instead of the clutch pedal 22. The present invention may be applied by using the parking brake pedal as a “first pedal”.

  Further, in the present embodiment, only the clutch pedal 22 is received by the restricting portion 20 and the displacement to the rear side of the vehicle is restricted, and the subject that contacts the contact portion 48 and presses the contact portion 48 is the brake. Only pedal 49. That is, in the present embodiment, there is one “first pedal” and one “second pedal”. However, each of the “first pedal” and the “second pedal” may be at least one of “a plurality of pedals”, and a plurality of “first pedals” and “second pedals” are set. It may be.

  Further, in the present embodiment, the under cover 10 for covering the steering column from the lower side is the “vehicle interior member” according to the present invention, but the “vehicle interior member” according to the present invention is used. However, the present invention is not limited to the under cover 10 and can be applied to any “vehicle interior member” provided behind a pedal such as the clutch pedal 22 or the brake pedal 49. Therefore, for example, even if the instrument panel 66 is extended so as to cover the steering column from the lower side and the restricting portion 22, the abutting portion 48, the notch 86 and the fracture portion 84 are formed on the instrument panel 66, The same operations and effects as those of the under cover 10 can be obtained.
