The collar 112 is fixed with its rear end fitted into the lower end 40 </ b> A of the pair of support members 40. The front end of the collar 112 in such a state protrudes toward the dash panel 100. Hereinafter, the position where the front end of the collar 112 contacts the dash panel 100 is referred to as a lower end fixing position LP.

  The same applies to the upper end portions 40B of the pair of support members 40. That is, at the upper end portions 40 </ b> B of the pair of support members 40, the pair of stud bolts 120 protruding rearward from the dash panel 100 penetrates while passing through the collar 122. By screwing the nut 124 into such a penetrating portion, the upper end portions 40B of the pair of support members 40 are fixed to the dash panel 100. The pair of stud bolts 120 are provided side by side in the vehicle width direction. The collar 122 is fixed with its rear end fitted to the upper end 40 </ b> B of the pair of support members 40. The front end of the collar 122 in such a state protrudes toward the dash panel 100. Hereinafter, the position where the front end of the collar 122 contacts the dash panel 100 is referred to as an upper end fixed position UP.

  However, the pair of stud bolts 120 are disposed below the master cylinder 104 provided in the brake booster 102 in the brake booster 102 abutting on the dash panel 100 from the front side of the vehicle. , And protrudes rearward from the dash panel 100.

  Further, the brake booster 102 is provided with a pair of stud bolts 130 above the master cylinder 104. The pair of stud bolts 130 are provided side by side in the vehicle width direction, and protrude rearward from the dash panel 100 while penetrating the dash panel 100. A nut 132 is screwed into the pair of stud bolts 130.

  Thus, the pair of support members 40 are fixed to the dash panel 100 from the vehicle rear side. Further, the brake booster 102 is fixed to the dash panel 100 from the front side of the vehicle, so that the master cylinder 104 projects rearward from the dash panel 100. The dash panel 100 constitutes a vehicle together with the brake booster 102 and the master cylinder 104.

  At the rear end of the master cylinder 104, the operating rod R projects rearward. The rear end of the operating rod R is rotatably held with respect to the upper end of the second pedal 30 via the clevis C and the connecting pin P. The upper end of the second pedal 30 is provided with a mounting hole H for receiving the connecting pin P.

  As described above, in the vehicle operation pedal device 10 of the present embodiment, a pair of dash panels 100 disposed on the vehicle front side with respect to the first pedal 20 and the second pedal 30 connected by the link member LM are provided. The support member 40 is fixed. In the pair of support members 40, the first pedal 20 and the second pedal 30 connected by the link member LM are rotatably supported by the first pedal support portion 60 and the second pedal support portion 80. A tread portion 22 provided at the lower end of one pedal 20 is suspended. Thus, among the members constituting the vehicle, only the dash panel 100 supports the vehicle operation pedal device 10 of the present embodiment.

  Therefore, the vehicle operation pedal device 10 of the present embodiment includes a pair of support members for the dash panel 100 disposed on the vehicle front side with respect to the first pedal 20 and the second pedal 30 connected by the link member LM. By fixing 40, the attachment to the vehicle is completed.

(2) Configuration of First Pedal Support and Second Pedal Support Next, the configuration of the first pedal support 60 will be described. As shown in FIG. 3, in the first pedal support portion 60, the boss 24 is welded to the first pedal 20 with the boss 24 penetrating the first pedal 20 in the left-right direction between the pair of support members 40. Fixed.

  A collar CO is fitted into the boss 24 with a pair of bushes BU fitted from the left and right ends thereof. Thereby, the cylindrical portion of each bush BU is provided between the boss 24 and the collar CO.

  A support hole 42 is provided in the pair of support members 40. Each support hole 42 has a circular shape in a side view, and is in a state of communicating in the left-right direction via a collar CO. In such a state, the bolt B is passed from the support hole 42 of the left support member 40 to the support hole 42 of the right support member 40.

  The head of the bolt B is abutted on the left support member 40. On the other hand, in the right support member 40, the tip of the bolt B protrudes rightward, and the nut N is screwed into the protruding portion. Thereby, since both ends of the collar CO are sandwiched between the pair of support members 40, the length of the first pedal support portion 60 in the left-right direction is kept constant. Further, at the left and right ends of the collar CO, the circular flange portions of each bush BU are provided between the collar CO and the support member 40.

  In this way, the first pedal 20 is rotatably supported by the first pedal support portion 60. The same applies to the second pedal support section 80. That is, in a case where FIG. 3 shows a cross section of the vehicle operation pedal device 10 of the present embodiment taken along line A2-A2 in FIG. 2, if the first pedal 20 is regarded as the second pedal 30 in FIG. , The first pedal support 60 represents the second pedal support 80. Therefore, description of the second pedal support 80 will be omitted. In this manner, the second pedal 30 is rotatably supported by the second pedal support 80.

  Therefore, when the driver of the vehicle depresses the tread portion 22 of the first pedal 20 toward the front side of the vehicle to perform a depressing operation on the tread portion 22 of the first pedal 20, the tread portion 22 of the first pedal 20 is moved to the second position. It makes a circular motion around the one pedal support 60 toward the front of the vehicle. On the other hand, when the stepping operation of the first pedal 20 with respect to the tread portion 22 is released, the tread portion 22 of the first pedal 20 is centered on the first pedal support portion 60 by the urging force of the urging member (not shown). And make a circular motion toward the rear of the vehicle. Such rotation of the first pedal 20 is transmitted to the second pedal 30 via the link member LM. Thereby, the second pedal 30 rotates around the second pedal support 80. Further, when the second pedal 30 rotates, the operating rod R moves in the front-back direction.

  When the operating rod R is displaced toward the front of the vehicle in accordance with the stepping operation of the first pedal 20 with respect to the tread portion 22, the operating force at the time of the stepping operation is changed through the hydraulic circuit or the electronic circuit to change the driving state of the vehicle. It is transmitted to the controlling braking device or control device.

(3) Positions of First Pedal Support and Second Pedal Support Next, the positions of the first pedal support 60 and the second pedal support 80 will be described. As shown in FIG. 1, when the tread portion 22 of the first pedal 20 is depressed toward the front of the vehicle, and a tread load FP acts on the tread portion 22 of the first pedal 20, the first pedal support portion 60 The first load F1 acts on the pair of support members 40 via the bolts B (see FIG. 3). The lower end fixed position LP exists at the start point of the vector representing the first load F1, that is, on the first straight line L1 extending from the rotation center point of the first pedal support portion 60 toward the direction of the vector. .

  That is, the first straight line L1 is a line connecting the rotation center point of the first pedal support portion 60 and the lower end fixed position LP when viewed from a direction perpendicular to the paper surface of FIG. . The lower end fixing position LP is a position where the front end of the collar 112 contacts the dash panel 100 as described above, but is also a position where the lower ends 40A of the pair of support members 40 are fixed to the dash panel 100. .

  Similarly, when the depression load FP acts on the tread portion 22 of the first pedal 20, the second load F2 acts on the pair of support members 40 via the bolts of the second pedal support portion 80. The start point of the vector representing the second load F2, that is, on the second straight line L2 extending from the rotation center point of the second pedal support 80 to the side opposite to the direction of the vector, the upper end fixed position UP Exists.

  That is, the second straight line L2 is a line connecting the rotation center point of the second pedal support portion 80 and the upper end fixed position UP when viewed from a direction perpendicular to the paper surface of FIG. . The upper end fixing position UP is a position where the front end of the collar 122 contacts the dash panel 100 as described above, but is also a position where the upper ends 40B of the pair of support members 40 are fixed to the dash panel 100. .

  In this manner, the first pedal support portion 60 is provided at a position closer to the lower end fixing position LP than the upper end fixing position UP. On the other hand, the second pedal support portion 80 is provided at a position closer to the upper end fixed position UP than the lower end fixed position LP.

(4) Conclusion As described in detail above, in the vehicle operation pedal device 10 of the present embodiment, the positions where the lower end portions 40A of the pair of support members 40 are fixed to the dash panel 100 (that is, the lower end fixing position LP). And the direction of the first straight line L1 connecting the rotation center point of the first pedal support portion 60 is the same as the direction of the first load F1. Therefore, at the time of the stepping operation, the first load F1 acting on the pair of support members 40 via the bolts B of the first pedal support portion 60 does not cause a rotational moment to act on the pair of support members 40. , Are received by the pair of support members 40. Therefore, in the vehicle operation pedal device 10 of the present embodiment, each cross section of the pair of support members 40 for receiving the first load F1 at the time of the stepping operation is minimized, thereby achieving weight reduction and cost reduction. It is possible.

  Further, in the vehicle operation pedal device 10 of the present embodiment, the position where the upper end portions 40B of the pair of support members 40 are fixed to the dash panel 100 (that is, the upper end fixing position UP), and the rotation of the second pedal support portion 80. The direction of the second straight line L2 connecting the moving center point is the same as the direction of the second load F2. Therefore, at the time of the stepping operation, the second load F2 acting on the pair of support members 40 via the bolts of the second pedal support portion 80 does not cause a rotational moment to act on the pair of support members 40, It is received by a pair of support members 40. Therefore, in the vehicle operation pedal device 10 of the present embodiment, each cross section of the pair of support members 40 for receiving the second load F2 at the time of the stepping operation is minimized, thereby further reducing the weight and cost. It is possible to achieve.

  In the vehicle operation pedal device 10 of the present embodiment, the first pedal 20 has a shape bent rightward in the vehicle width direction from between the pair of support members 40. In the first pedal 20 having such a shape, when the tread portion 22 located on the right side in the vehicle width direction with respect to the right support member 40 is stepped on, the torsional moment is applied via the bolt B of the first pedal support portion 60. And acts on the pair of support members 40. However, as described above, since no rotational moment is generated in the pair of support members 40, it is ensured that the weight and cost can be reduced even under the condition where the torsional moment acts.

  Incidentally, in the present embodiment, the dash panel 100 is an example of a “vehicle constituent member”. The first straight line L1 is an example of a “straight line connecting the lower end fixed position and the first pedal support portion”. The second straight line L2 is an example of “a straight line connecting the upper end fixed position and the second pedal support portion”. The first load F1 is an example of “a load that acts on the first pedal support portion when the first pedal is depressed”. The second load F2 is an example of “a load that acts on the second pedal support when the first pedal is depressed”.

(5) Others The present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the present invention.

  For example, when viewed from a direction perpendicular to the paper surface of FIG. 1 (that is, the left-right direction), even if the rotation center point of the first pedal support unit 60 is not on the first straight line L1, it may be on the second straight line L2. If there is a rotation center point of the second pedal support 80, the weight and cost of the pair of support members 40 can be reduced. Further, even if there is no center of rotation of the second pedal support 80 on the second straight line L2, if there is a center of rotation of the first pedal support 60 on the first straight line L1, a pair of support members 40 may be provided. Can be reduced in weight and cost.

  Further, the pair of support members 40 may be fixed in contact with the dash panel 100 without the collar 112 and the collar 122 interposed therebetween.

  Further, the first pedal 20 may be configured by an upper member 20A, a lower member 20B, and a boss 26 as shown in FIG. In such a case, the upper end of the upper member 20A is connected to the lower end of the second pedal 30 by a link member LM. The lower member 20B is provided with a tread portion 22 at the lower end. The boss 26 penetrates the lower end of the upper member 20A and the upper end of the lower member 20B in the left-right direction between the pair of support members 40, and the lower end of the upper member 20A and the upper end of the lower member 20B. Is fixed by welding. Thus, the lower member 20B is disposed via the boss 26 on the right side in the vehicle width direction with respect to the upper member 20A. In addition, about the other structure, the detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol to the part substantially common to the said embodiment.

  The first pedal 20 in FIG. 4 is rotatably supported by the first pedal support portion 60 in FIG. 3 with the boss 24 changed to the boss 26. Accordingly, the upper member 20A and the lower member 20B rotate integrally with the pair of support members 40 via the boss 26. Accordingly, even when the tread portion 22 is stepped on the upper member 20A and the lower member 20B, no torsional moment is generated, so that it is further ensured that the pair of support members 40 are reduced in weight and cost.

  Further, in the first pedal support portion 60, for example, as shown in FIG. 5, a rotating shaft RS may be used instead of the bolt B and the nut N in FIG. In such a case, the left and right ends of the rotation shaft RS protrude from the pair of support members 40 in the left and right direction, and caulking is performed on those protruding portions. This is the same for the second pedal support portion 80.

  Further, in the present embodiment, the present invention is applied with the first pedal 20 as a brake pedal, but the present invention may be applied as each pedal (for example, an accelerator pedal or a clutch pedal) used in a vehicle. .
