Description

The present invention relates to a foot-operated pedal device for vehicles. More specifically, the present invention relates to a foot-operated pedal device for a vehicle, which includes a stroke sensor for detecting the amount of rotation of the pedal arm, and is provided with a sensor mounting bracket for mounting the stroke sensor on the pedal support bracket.

Vehicles such as automobiles are equipped with various foot-operated pedal devices. One of them is a regular foot-operated brake pedal device. This type of foot-operated brake pedal device is equipped with a stroke sensor that detects the amount of rotation of the pedal arm, and various controls are performed based on the depression of the brake pedal (Patent Documents below). See 1 and 2).

The foot-operated brake pedal device is attached to a pedal support bracket attached to a vehicle by rotatably supporting the pedal arm. Then, the brake operation is performed by stepping on the foot-operated portion of the pedal arm with the foot and rotating the pedal arm. The stroke sensor provided in this foot-operated brake pedal device is assembled to the sensor mounting bracket fixedly installed on the side surface of the flat plate-shaped portion of the pedal support bracket.

When assembling the stroke sensor to the sensor mounting bracket, two assembly holes formed corresponding to the stroke sensor are fitted into a rod-shaped member such as two bolts installed at intervals from the sensor mounting bracket. By matching, it is assembled. The sensor mounting bracket is usually formed in an oval shape or a rectangular shape, and rod-shaped members such as two bolts are arranged at intervals in the longitudinal direction. A long hole for assembling is formed in the stroke sensor corresponding to the arrangement of the two rod-shaped members, and after assembling, the stroke sensor is fastened and fixed by a nut or the like.

Usually, the sensor mounting bracket to which the stroke sensor is assembled is arranged in parallel on the pedal support bracket so that the installation portion where the stroke sensor is installed is separated from the side surface of the flat plate-shaped portion of the pedal support bracket. Therefore, fixing flanges that support the assembling load when assembling the stroke sensor to the sensor mounting bracket are formed at both ends in the longitudinal direction of the sensor mounting bracket if there is no problem in arrangement. Then, the pedal support bracket is joined and fixed to the side surface of the flat plate-shaped portion by welding or the like to support the assembled load of the stroke sensor.

By the way, in the above-mentioned foot-operated brake pedal device, if the fixing flanges that support the assembly load in the assembly of the stroke sensor can be arranged at both ends in the longitudinal direction of the sensor mounting bracket, the assembly load has both sides. It becomes supportive and causes almost no problems. This is because the sensor mounting bracket does not bend and deform due to the pushing load on the rod-shaped members such as two bolts when assembling the stroke sensor, and the stroke sensor can be smoothly assembled to the sensor mounting bracket.

However, devices of various devices are arranged around the sensor mounting bracket to which the stroke sensor is assembled. Therefore, the fixing flange for welding the stroke sensor to the sensor mounting bracket may be set only on one end side in the longitudinal direction. In this case, the support form of the sensor mounting bracket by the fixing flange to the pedal support bracket is a so-called cantilever support form. Therefore, the pedal support bracket may be bent and deformed due to the pushing load when the stroke sensor is assembled to the sensor mounting bracket, and the assembly may not be performed smoothly.

The contents of the above problems will be described with reference to FIGS. 12 to 17. FIG. 12 shows a plan view of the sensor mounting bracket 124 alone, and FIG. 13 shows a perspective view. FIG. 14 shows a side view of the sensor mounting bracket mounted on the pedal support bracket 112. As shown in FIGS. 12 and 13, the installation portion 134 of the sensor mounting bracket 124 on which the stroke sensor 128 (see FIGS. 15 to 17) is installed is formed in a substantially oval shape of deformation, and is formed in FIGS. 12 and 13. Two fixing flanges 138A and 138B are formed on the left end side of the oval shape as viewed from No. 13. The two fixing flanges 138A and 138B are fixedly attached to the pedal support bracket 112 as shown in FIG. 14 by spot welding at the locations indicated by x in the figure. In the form shown in FIGS. 12 to 14, it is difficult to dispose the fixing flange 138 because other devices are arranged on the right side of the sensor mounting bracket 124 in the drawing.

As shown in FIGS. 12 and 13, a relatively large-diameter round hole 136 is formed at a substantially central position of the installation portion 134 in which the stroke sensor 128 (see FIGS. 15 to 17) of the sensor mounting bracket 124 is installed. It is installed. Two bolts 126 for assembling the stroke sensor 128 are fixedly set at positions on both sides of the round hole 136 in the longitudinal direction of the sensor mounting bracket 124 in a protruding form. Therefore, in this arrangement mode, as shown in FIG. 14, the sensor mounting bracket 124 is mounted on the pedal support bracket 112 in a cantilever support state by the fixing flange 138 arranged on one side.

15 to 17 show a state in which the stroke sensor 128 is assembled to the sensor mounting bracket 124 in the cantilever support state described above. FIG. 15 shows a state before assembling the stroke sensor 128. FIG. 16 shows a state when the stroke sensor 128 is normally assembled. FIG. 17 shows a state at the time of assembly deformation. Two assembly holes 146A and 146B into which two bolts 126A and 126B attached to the sensor mounting bracket 124 are fitted are formed on both sides of the stroke sensor 128. The stroke sensor 128 is shown with diagonal lines as an image of the outer shape of the entire configuration.

The stroke sensor 128 is assembled to the sensor mounting bracket 124 by fitting the two assembly holes 146A and 146B of the stroke sensor 128 into the two bolts 126A and 126B of the sensor mounting bracket 124. FIG. 15 shows the state before the fitting, and FIG. 16 shows the state in which the fitting is normally performed. However, if there is a misalignment between the bolt 126 and the assembly hole 146 during assembly, the sensor mounting bracket 124 bends and deforms as shown in FIG. 17 due to the pushing load of the stroke sensor 128 into the bolt 126. When the bolts are bent and deformed, the bolts 126B are arranged in an inclined manner, and the positions are further displaced, which makes fitting difficult and the assembly work cannot be performed smoothly.

Therefore, the present invention was devised in view of the above-mentioned problems, and the problem to be solved by the present invention is that the arrangement form of the fixing flange for joining and fixing the sensor mounting bracket to the pedal support bracket is one-sided. Even in the holding support state, when the stroke sensor is assembled to the sensor mounting bracket, the bending deformation of the sensor mounting bracket is prevented or suppressed, and the assembling is performed smoothly.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The foot-operated pedal device for vehicles of the present embodiment is a foot-operated brake pedal device for vehicles equipped as a regular braking device in a vehicle. In addition, the configuration of the device shown in the drawing may be drawn with a part of the basic configuration omitted, and the dimensional ratio and the like of each drawn portion are not always accurate. Further, the directions in FIGS. 1 and 2 are the left-right direction, the front-back direction, and the up-down direction described in the figure, and this direction display is shown with reference to the posture state in the normal traveling direction of a vehicle such as an automobile. There is.

First, the overall configuration of the foot-operated brake pedal device 10 for a vehicle according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 shows a plan view of the brake pedal device 10 of the present embodiment when viewed from the left side of the vehicle, and FIG. 2 shows a perspective view of the device 10 as viewed from the upper left of the vehicle. The foot-operated brake pedal device 10 for a vehicle is arranged and installed at a position below the front portion of the driver's seat that can be operated by the driver with his / her foot in a vehicle such as an automobile. The device 10 includes a pedal support bracket 12, a pedal arm 16, a stroke sensor 28 (see FIG. 11), and a sensor mounting bracket 24.

The pedal support bracket 12 is composed of a left side plate 12L, a right side plate 12R, and a rear connecting plate 12B. The left side plate 12L and the right side plate 12R are formed as substantially flat plate-shaped portions 12S, and are arranged at intervals in the left-right direction. A rear connecting plate 12B is arranged between the rear positions of the left side plate 12L and the right side plate 12R arranged at intervals, and the left side plate 12L and the right side plate 12R are integrally connected. The pedal support bracket 12 is attached and fixed to the dash panel 14 in the front position, and is attached and fixed to the instrument panel reinforcement (not shown) in the rear position.

That is, at the front position, the front end portions of the left side plate 12L and the right side plate 12R are bent to form the mounting flanges 12Lf and 12Rf, which are mounted and fixed to the dash panel 14 shown in FIG. 1 by bolts or the like. In the rear position, the rear connecting plate 12B is attached and fixed to the instrument panel reinforcement (not shown). The instrument panel reinforcement is a member that is arranged as a strength member in the left-right direction at the front position of the passenger compartment of the vehicle by bridging the body members on both the left and right sides. In this way, the pedal support bracket 12 is firmly attached to the vehicle at two positions, the front position and the rear position.

The pedal arm 16 is a member in which the driver of the vehicle performs a braking operation by stepping on the foot. Therefore, as seen in FIGS. 1 and 2, a stepping operation portion 18 is provided at the lower end portion of the pedal arm 16. The stepping operation unit 18 is commonly referred to as a pedal pad. The upper portion of the pedal arm 16 is inserted and arranged in the gap between the left side plate 12L and the right side plate 12R of the pedal support bracket 12, and is rotatably supported and attached to the pedal support bracket 12. Has been done. Specifically, the pedal support bracket 12 is pivotally supported by the shaft pin 20 at the flat plate-shaped portion 12S of the left side plate 12L and the right side plate 12R. As a result, the pedal arm 16 is configured to be rotatable around the shaft pin 20.

A return spring 22 is suspended from the pedal arm 16 with the rear connecting plate 12B of the pedal support bracket 12. The return spring 22 acts to return the pedal arm 16 rotated by the brake operation to the initial position after the brake operation is released. The member indicated by reference numeral 52 in FIGS. 1 and 2 is a rotating link lever linked to the pedal arm 16 and is rotated by a shaft pin 54 to the pedal support bracket 12 of the left side plate 12L and the right side plate 12R. It is supported as much as possible. By stepping on the pedal arm 16, the rotation link lever 52 rotates forward with the shaft pin 54 as the rotation axis. As a result, the brake operating rod mounting portion 56 set in the upper portion moves forward. As a result, a brake operating rod (not shown) is operated to generate a braking force by the brake master cylinder or the like to perform a braking action.

The sensor mounting bracket 24 is mounted in parallel on the left side surface of the flat plate-shaped portion 12S on the left side plate 12L of the pedal support bracket 12 in a separated arrangement state. Then, the stroke sensor 28 (not shown in FIGS. 1 and 2) shown in FIG. 11 is assembled and attached to the sensor mounting bracket 24. The stroke sensor 28 is a device for detecting the amount of rotation of the pedal arm 16. Since the configuration in which the sensor mounting bracket 24 is arranged on the pedal support bracket 12 is a feature of this embodiment, details will be described later.

3 to 5 are embodiments in the case where the stopper means 30 set on the sensor mounting bracket 24 characterized by the present embodiment is the stopper flange 32. 3 and 4 show a single product of the sensor mounting bracket 24, FIG. 3 is a plan view, and FIG. 4 is a perspective view. FIG. 5 shows a state in which the sensor mounting bracket 24 is mounted on the pedal support bracket 12. As shown in FIGS. 3 and 4, the sensor mounting bracket 24 has an oval shape in which the shape of the installation portion 34 on which the stroke sensor 28 is installed is deformed. Specifically, the shape is such that the central portion in the oval direction is bulged. A large-diameter round hole 36 is formed at the bulging position. The sensor mounting bracket 24 is made of steel plate.

Two bolts 26 are provided on both sides of the round hole 36 in the longitudinal direction of the sensor mounting bracket 24. The bolt 26 corresponds to the rod-shaped member of the present invention. When these two bolts 26 are individually designated, they are distinguished as one bolt 26A and the other bolt 26B. One bolt 26A and the other bolt 26B are symmetrically positioned with the round hole 36 in between, and are arranged at intervals. The bolt 26 includes a head H as shown in FIG. 5, and the head H is welded and fixed to the lower surface of the installation portion 34 of the sensor mounting bracket 24 as seen in FIG. As shown in FIG. 3, the center C of the round hole 36 is located on the connection line X connecting one bolt 26A and the other bolt 26B, and the center C of one bolt 26A and the other bolt 26B It is in the middle position.

The sensor mounting bracket 24 is provided with a fixing flange 38 similar to the conventional one. The fixing flange 38 is formed at a position close to one of the bolts 26A. In the present embodiment, the "close position" means a position closer to the one bolt 26A and the other bolt 26B when compared in a straight line distance. Two fixing flanges 38 are formed in this embodiment. As seen in FIG. 3, it is composed of a first fixing flange 38A formed in the direction of the connecting line X connecting the two bolts 26 and a second fixing flange 38B formed in the direction orthogonal to the connecting line X. Both the fixing flanges 38 are formed in an L-shaped cross section, and are composed of an upright portion 40 and a fixing surface portion 42 as shown well in FIG. Both of the two fixing flanges 38 are integrally formed with the installation portion 34 of the sensor mounting bracket 24.

The upright portion 40 of the fixing flange 38 is arranged so as to be separated from the flat plate-shaped portion 12S when the sensor mounting bracket 24 is arranged on the left side plate 12L of the pedal support bracket 12 as shown in FIG. It is a part for. The fixed surface portion 42 is a portion to be fixedly attached to the flat plate-shaped portion 12S of the pedal support bracket 12 by spot welding, whereby the sensor mounting bracket 24 is attached to the pedal support bracket 12 in a fixed state. In FIGS. 3 to 5, the spot welded portion on the fixed surface portion 42 is indicated by a cross. The same is shown in FIGS. 1 and 2.

Next, the sensor mounting bracket 24 is set with a stopper flange 32, which is a feature of the present embodiment. The stopper flange 32 is set at a position close to the other bolt 26B. The stopper flange 32 corresponds to the stopper means 30 of the present invention. In the embodiment shown in FIGS. 3 to 5, the stopper flange 32 is integrally formed with the installation portion 34 of the sensor mounting bracket 24. The position where the stopper flange 32 is formed is within the outer shape range of the installation portion 34 of the sensor mounting bracket 24. In the present embodiment, the term “within the outer shape range” means a shape in which the plate thickness is slightly projected when the outer surface of the installation portion 34 is bent and formed. However, although the stopper flange 32 shown in FIGS. 3 to 5 is formed so as to slightly protrude from the outer shape of the installation portion 34, it is considered to be within the outer shape range because it is a protrusion corresponding to the plate thickness of the installation portion 34. Is what is done.

As shown in FIG. 5, the stopper flange 32 is formed by bending the end surface portion of the installation portion 34 of the sensor mounting bracket 24 toward the flat plate-shaped portion 12S of the left side plate 12L of the pedal support bracket 12. The tip of the stopper flange 32 (lower end as seen in FIG. 5) is formed so as to be arranged in a non-fixed state on the flat plate-shaped portion 12S of the left side plate 12L of the pedal support bracket 12. Specifically, in the present embodiment, the distance between the pedal support bracket 12 and the sensor mounting bracket 24 by the upright portion 40 of the fixing flange 38 is set to 10 to 15 mm. On the other hand, the gap between the stopper flange 32 and the pedal support bracket 12 in which the tip is not fixed is set to 2 to 3 mm.

FIG. 11 shows an example of the stroke sensor 28 assembled to the sensor mounting bracket 24 described above. The stroke sensor 28 is a device for detecting the amount of rotation of the pedal arm 16. Two assembly holes 46 are provided on both sides of the device main body 44 of the stroke sensor 28, and are fitted into bolts 26 of the sensor mounting bracket 24 for mounting. Specifically, the two assembly holes 46 consist of a first assembly hole 46A and a second assembly hole 46B, the first assembly hole 46A is fitted into one of the bolts 26A, and the second assembly hole 46B. Is fitted into the other bolt 26B. The stroke sensor 28 is provided with a sensor lever 48. The sensor lever 48 is locked in a locking hole 60 formed in the bumper bracket 58 shown in FIGS. 1 and 2, and serves to transmit the rotation of the pedal arm 16 to the stroke sensor 28. The bumper bracket 58 is welded to the pedal arm 16 and integrally connected.

FIG. 6 shows a state in which the stroke sensor 28 is assembled to the sensor mounting bracket 24. In FIG. 6, the stroke sensor 28 is shown simplified as a shaded block diagram. The stroke sensor 28 is assembled by fitting the first assembly hole 46A into one bolt 26A and the second assembly hole 46B into the other bolt 26B. The load support at the time of this fitting is performed by the pedal support bracket 12 of the left side plate 12L via the sensor mounting bracket 24. Specifically, it is performed by the fixing flange 38 and the stopper flange 32 formed on the sensor mounting bracket 24.

Two fixing flanges 38 are arranged, but both are arranged at positions close to one of the bolts 26A. Therefore, in fitting the stroke sensor 28, the supporting load acting on one of the bolts 26A is supported exclusively via the fixing flange 38. Further, the stopper flange 32 is arranged at a position close to the other bolt 26B. Therefore, in fitting the stroke sensor 28, the supporting load acting on the other bolt 26B is supported exclusively via the stopper flange 32.

In addition, the support by the fixing flange 38 is supported by joining and fixing the fixing surface portion 42 to the left side plate 12L of the pedal support bracket 12 by spot welding as in the conventional case. The support by the stopper flange 32 having the configuration characterized by the present embodiment is supported by disposing the tip of the stopper flange 32 and the pedal support bracket 12 of the left side plate 12L in a non-fixed state. This non-fixed support is supported by preventing or suppressing substantial bending deformation of the sensor mounting bracket 24 when the stroke sensor 28 is assembled. Therefore, in the present embodiment, the gap interval for the non-fixed state is set to 2 to 3 mm as described above. In this embodiment, the gap spacing is formed in order to prevent abnormal noise caused by the tip of the stopper flange 32 hitting the pedal support bracket 12 while the vehicle is running. Therefore, if abnormal noise is not a problem, the gap interval may be set to 0 mm, that is, the contact state may be arranged as a non-fixed state.

Further, as a countermeasure against the above-mentioned impact noise, an elastic body such as rubber or a cushioning material (not shown) such as felt may be set at the tip of the stopper flange 32. Also in this case, the gap spacing at the tip of the stopper flange 32 can be set to 0 mm. However, if the bending deformation level does not hinder the assembly of the stroke sensor 28, a gap may be provided.

As described above, in the present embodiment, the supporting load generated when the stroke sensor 28 is assembled is supported by the fixing flange 38 and the stopper flange 32 which are arranged at intervals on the sensor mounting bracket 24. As a result, it is possible to prevent or suppress the bending deformation of the sensor mounting bracket 124 at the time of assembling as shown in FIG. Then, the stroke sensor 128 can be easily and surely assembled to the sensor mounting bracket 124.

FIG. 7 shows a modified example of the stopper flange 32 in the above embodiment. The stopper flange 32 is integrally formed with the installation portion 34 of the sensor mounting bracket 24, but the stopper flange 33 of this modified example is detachably configured. Therefore, the stopper flange 33 is formed with a holding portion 50 for sandwiching the edge portion of the installation portion 34. The sandwiching portion 50 enables the stopper flange 33 to be attached and detached.

In the detachable stopper flange 33 described above, the stopper flange 33 can be attached only when the stroke sensor 28 is assembled, and can be removed after the assembly. As a result, weight reduction in normal times can be achieved.

FIG. 8 shows a case where one fixing flange 38 is formed on the sensor mounting bracket 24. In the embodiment shown in FIG. 8, the fixing flange 38B is deleted from the two fixing flanges 38A and 38B in the embodiments shown in FIGS. 3 and 4. As a result, the number of welding points to be joined and fixed to the pedal support bracket 12 is one, and a simple structure can be obtained. As a result, the sensor mounting bracket 24 can be shared with other vehicle models, and versatility can be improved. Further, the weight can be reduced by the amount that the fixing flange 38B is deleted, and the weight increase due to the installation of the stopper flange 32 can be offset.

Further, the arrangement position of the fixing flange 38 and the arrangement position of the stopper flange 32 shown in FIG. 8 are opposite positions sandwiching the connection line X connecting one bolt 26A and the other bolt 26B. As a result, the arrangement of the sensor mounting bracket 24 becomes stable.

Next, another embodiment of the stopper means 30 shown in FIGS. 9 and 10 will be described. The stopper means 30 of the embodiment shown in FIGS. 9 and 10 is set by the head H of the other bolt 26B installed on the sensor mounting bracket 24. In the present embodiment, as shown in FIG. 10, the height of the head H of the other bolt 26B is set high so that the pedal support bracket 12 and the stopper flange 32 described above are arranged in the same non-fixed state. It is a thing. As a result, the head H of the other bolt 26B has the same effect as that of the stopper flange 32 described above, and acts to prevent or suppress the bending deformation of the sensor mounting bracket 24 when the stroke sensor 28 is assembled.

When the stopper means 30 is set on the other bolt 26B described above, the position of the stopper means 30 is the position closest to the other bolt 26B. A cushioning material may be provided at the tip of the head H of the other bolt 26B as a countermeasure against hitting noise as in the case of the stopper flange 32.

As another means of preventing or suppressing bending deformation during assembly of the stroke sensor 28 in a configuration in which the sensor mounting bracket 24 is cantilevered, a rib flange for reinforcement is provided around the installation portion 34 of the sensor mounting bracket 24. There is a way to form. However, since the reinforcing rib flange is formed over the entire circumference around the installation portion 34, there is a disadvantage that the weight of the sensor mounting bracket 24 is significantly increased by that amount.

Although the present invention has been described above with respect to specific embodiments, the present invention can also be implemented in various other embodiments.

For example, in the above embodiment, the foot pedal device for a vehicle is a place of a regular brake pedal device, but it is applied to various foot pedal devices such as a parking brake device and an accelerator pedal device used for a vehicle. Can be done.

Further, in the above embodiment, the fixing surface portion 42 of the fixing flange 38 is joined and fixed to the pedal support bracket 12 by spot welding, but other welding means may be used, and a joining means other than welding, for example, It may be by an adhesive means.

Further, in the above embodiment, the stopper means 30 is arranged within the outer shape range of the sensor mounting bracket 24, but may be arranged outside the outer shape range.

Further, although the stopper flange 32 as the stopper means 30 in the above embodiment is set at one place, it may be set at two or more places.

Further, although the stopper flange 32 in the above embodiment is formed at the outer peripheral end portion of the installation portion 34 in the sensor mounting bracket 24, the stopper flange 32 may be formed by a single portion obtained by cutting out the surface of the installation portion 34.

Further, the stopper means 30 by the stopper flange 32 in the above embodiment and the stopper means 30 set as the height of the head H in the other bolt 26B may be juxtaposed.

Finally, the action and effect of the above-described embodiment corresponding to each invention in the above-mentioned "means for solving the problem" will be added.

First, according to the first aspect of the present invention, a fixing flange and a stopper means are installed on a sensor mounting bracket provided with two rod-shaped members for assembling a stroke sensor. Then, the fixing flange is arranged at a position close to one of the two rod-shaped members arranged at intervals, and is joined and fixed to the side surface of the flat plate-shaped portion of the pedal support bracket. .. The stopper means is arranged at a position close to the other rod-shaped member, and is set in a non-fixed state with respect to the pedal support bracket so as to prevent or suppress bending deformation of the sensor mounting bracket. Therefore, the fixing flange and the stopper means are also arranged at intervals like the two rod-shaped members. As a result, the mounting load support when mounting the stroke sensor on the sensor mounting bracket becomes a support in the form of holding both the fixing flange and the stopper means arranged at intervals. Moreover, the stopper means is arranged so as to prevent or suppress the bending deformation of the sensor mounting bracket. As a result, the sensor mounting bracket can be reliably and easily mounted on the pedal support bracket.

Next, according to the second invention of the present invention, the stopper means in the first invention described above is a stopper flange arranged on the sensor mounting bracket. As a result, the stopper means can have a simple flange configuration, and an increase in weight can be suppressed.

Next, according to the third invention of the present invention, the stopper flange in the second invention described above is configured to be arranged within the outer shape range of the sensor mounting bracket. As a result, a space other than the outer shape range of the sensor mounting bracket is not required to dispose the stopper flange.

Next, according to the fourth invention of the present invention, the stopper flange in the second invention or the third invention described above is integrally formed with the sensor mounting bracket. As a result, the stopper flange can be configured without increasing the number of parts.

Next, according to the fifth invention of the present invention, the stopper flange in the second or third invention described above is detachably attached to the sensor mounting bracket. As a result, the stopper flange can be removed from the sensor mounting bracket after the stroke sensor is attached to the sensor mounting bracket, and when the stopper flange is removed, the weight can be reduced by that amount. When removed, the space for arranging the sensor mounting bracket and the pedal support bracket becomes wider. As a result, it is possible to prevent or suppress an abnormal impact noise that occurs when the stopper flange comes into contact with the pedal support bracket while the vehicle is running.

Next, according to the sixth invention of the present invention, the rod-shaped member in the first invention described above is a bolt having a head, and the stopper means is configured to be set by the height of the head of the bolt. As a result, the stopper means can be configured by the head of the bolt, so that the stopper means can be configured without increasing the number of parts.

Next, according to the seventh invention of the present invention, there is only one fixing flange in each of the above-mentioned inventions. As a result, the space for joining and fixing the fixing flange to the pedal support bracket can be minimized. Further, as a result, the fixing flange can be made to have a simple structure, and space restrictions are reduced. As a result, the versatility can be improved, and the sensor mounting bracket can be shared with other vehicle models.

Next, according to the eighth invention of the present invention, the position of the fixing flange and the arrangement position of the stopper means in each of the above-described inventions are opposite positions sandwiched on the connecting line connecting the two rod-shaped members. ing. As a result, the arrangement of the sensor mounting bracket is stable.
