[Technical Field]
[0001] The present invention relates to an accelerator device. [Background technology]
[0002] 2. Description of the Related Art Conventionally, a reaction force applying device is known that can apply a reaction force to a pedal of an accelerator device that has a pedal that is depressed by a driver, in response to the depression force of the pedal by the driver.
[0003] For example, the accelerator device described in Patent Document 1 includes an arm to which a reaction force is applied from a reaction force application device. The arm has an end opposite to the end to which the reaction force from the reaction force application device is applied, and the end of the arm is fixed to the pedal of the accelerator device by two fastening members. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 6325094 Summary of the Invention [Problem to be solved by the invention]
[0005] In the accelerator device described in Patent Document 1, a through-hole through which a fastening member can be inserted is formed in the arm. To ensure assembly compatibility with variations in the shapes of the arm and pedal, a predetermined gap is formed between the through-hole and the fastening member. This gap may result in variations in the assembly position of the arm relative to the pedal. This may result in variations in the reaction force applied to the arm by the reaction force applying device.
[0006] An object of the present invention is to provide an accelerator device that can suppress variations in assembly position while ensuring ease of assembly of members. [Means for solving the problem]
[0007] The accelerator device according to the present invention includes a pedal (70), an arm (80), a fastening member (62), and a positioning portion (90). The pedal is operated by a driver by depressing the pedal. The arm is connected to the pedal and receives a reaction force from a reaction force applying device that is capable of applying a reaction force to the pedal force applied by the driver.
[0008] The fastening member can fix the arm to the pedal. The positioning portion can restrict relative movement between the arm and the pedal. The arm has a connection portion (82) that connects to the pedal and a through-hole portion (84) provided in the connection portion so that the fastening member can be inserted therethrough.
[0009] The positioning portion has two parallel positioning flat portions (91, 911, 912, 941, 942, 951, 952) that can engage with other components. Therefore, engagement between the two positioning flat portions and other components allows relative movement between the arm and the pedal in a direction parallel to the positioning flat portions, while restricting relative movement between the arm and the pedal in a direction perpendicular to the positioning flat portions. This ensures ease of assembly by allowing relative movement between the arm and the pedal in a direction parallel to the positioning flat portions, while restricting relative movement between the arm and the pedal in a direction perpendicular to the positioning flat portions can suppress variation in assembly position. Therefore, it is possible to both ensure ease of assembly of components and reduce variation in assembly position. In a first aspect of the present invention, a plurality of fastening members are provided, and the positioning plane portion is parallel to a straight line (L1) connecting two of the plurality of fastening members. In a second aspect of the present invention, the arm has a reaction force receiving abutment surface (83) that is capable of abutting against a lever (40) of a reaction force applying device that applies a reaction force to the arm, and that receives the reaction force. The positioning flat portion is parallel to the reaction force receiving abutment surface. In a third aspect of the present invention, the positioning portion has a positioning recess (92, 921, 922, 94) provided on one of the pedal or the connecting portion, and a positioning protrusion (93, 931, 932, 95, 961) provided on the other of the pedal or the connecting portion and capable of fitting into the positioning recess. The positioning flat portion is provided on at least the positioning recess of the positioning recess or the positioning protrusion. [Brief explanation of the drawings]

[0011] Hereinafter, accelerator devices and reaction force application devices to which the accelerator devices are applied according to several embodiments will be described with reference to the drawings. Note that substantially the same components in several embodiments will be given the same reference numerals, and descriptions thereof will be omitted.
[0012] (First embodiment) An accelerator device according to a first embodiment and a reaction force applying device to which the accelerator device is applied are shown in FIGS.
[0013] The accelerator device 60 is mounted on the vehicle 1 and is used to detect the accelerator opening corresponding to the rotation angle of a pedal 70 depressed by the driver, and to control the driving state of the vehicle 1. The accelerator device 60 employs an accelerator-by-wire system and is not mechanically connected to the throttle device of the vehicle 1. The accelerator device 60 transmits information relating to the accelerator opening corresponding to the rotation angle of the pedal 70 to an electronic control unit (hereinafter referred to as "ECU"), not shown. The ECU controls the throttle device based on the accelerator opening transmitted from the accelerator device 60. In this way, the driving state of the vehicle 1 is controlled.
[0014] The reaction force applying device 10 is mounted on the vehicle 1 together with the accelerator device 60, and is capable of applying a reaction force F2 to the pedal 70 of the accelerator device 60 in response to a depression force F1 by the driver. By applying a reaction force to the pedal 70 of the accelerator device 60, the reaction force applying device 10 can provide the driver with notifications such as danger notices and fuel efficiency improvement notices. Furthermore, by restricting the rotation of the pedal 70, the reaction force applying device 10 can turn the pedal 70 into a footrest.
[0015] In Figure 1, the x-axis indicates the direction of travel of the vehicle 1, the y-axis indicates the vehicle width direction, and the z-axis indicates the vertically upward direction. Unless otherwise specified, the following describes the shape or configuration of the accelerator device 60 and the reaction force applying device 10 when attached to the vehicle 1. For example, "above" or "upper side" means above or on the upper side when the accelerator device 60 or the reaction force applying device 10 is attached to the vehicle 1. In addition, in this embodiment, the floor panel 2 has a wall surface 7 that is parallel to the yz plane.
[0016] As shown in Figures 1-4, <1> The accelerator device 60 includes a pedal 70, an arm 80, a fastening member 62, and a positioning portion 90. The pedal 70 is operated by the driver by depressing it. The arm 80 is provided to be connected to the pedal 70, and receives a reaction force from a reaction force application device 10 that is capable of applying a reaction force to the pedaling force of the driver.
[0017] The fastening member 62 can fix the arm 80 to the pedal 70. The positioning portion 90 can restrict relative movement between the arm 80 and the pedal 70. The arm 80 has a connection portion 82 that connects to the pedal 70, and a through-hole portion 84 provided in the connection portion 82 so that the fastening member 62 can be inserted therethrough.
[0018] The positioning portion 90 has two positioning flat portions 91 that are parallel to each other and can be engaged with another member.
[0019] More specifically, the accelerator device 60 includes a pedal housing 61. The pedal housing 61 is attached to the floor panel 2 by being fixed to the wall surface 7 of the floor panel 2 of the vehicle 1 with, for example, mounting bolts (not shown).
[0020] The pedal 70 is rotatably supported by the pedal housing 61 so as to rotate around a rotation axis Ax1. The pedal 70 is provided with a pad 71 that is depressed by the driver. An accelerator opening sensor (not shown) is provided on the rotation axis Ax1 inside the pedal housing 61. The accelerator opening sensor detects the accelerator opening corresponding to the rotation angle of the pedal 70, which rotates when the driver depresses it, and transmits this to the ECU. The rotation axis Ax1 is set to be perpendicular to the z-axis and x-axis and parallel to the y-axis.
[0021] A pedal biasing member (not shown) is provided inside the pedal housing 61. The pedal 70 is biased in the accelerator closing direction by the pedal biasing member. The pedal housing 61 has a stopper that restricts rotation of the pedal 70 in the accelerator closing direction, and a stopper that restricts rotation in the accelerator opening direction. The pedal 70 is rotatable within a range in which it abuts against both stoppers. Figure 1 shows a state in which the pedal 70 abuts against the stopper in the accelerator closing direction, i.e., the accelerator is fully closed.
[0022] The pedal 70 has a pad 71, a pedal base 72, and a pedal connection portion 73. The pedal connection portion 73 is formed of, for example, metal, and connects the pad 71 and the pedal base 72 such that one end is connected to the pad 71 and the other end is connected to the pedal base 72. The pedal base 72 is rotatably supported by the pedal housing 61 so as to rotate around the rotation axis Ax1. This allows the pedal 70 to rotate around the rotation axis Ax1.
[0023] The arm 80 is formed in the shape of a long plate, and is attached to the pedal 70 so that a connection portion 82 at one end thereof is connected to the pedal base portion 72. This allows the arm 80 to rotate together with the pedal 70 around the rotation axis Ax1.
[0024] 1 and 2, the reaction force application device 10 includes an actuator 20 and a lever 40. The actuator 20 generates a driving force when energized. The lever 40 rotates due to the driving force from the actuator 20, and can apply a reaction force to the pedal 70 in response to the driver's depression force.
[0025] More specifically, the reaction force applying device 10 includes an actuator housing 11. The actuator housing 11 is attached to the floor panel 2 via the pedestal 9 by being fixed to the floor panel 2 by, for example, a mounting bolt (not shown) on a pedestal 9 provided on a wall surface 7 of the floor panel 2 of the vehicle 1.
[0026] The actuator 20 is, for example, an electric motor, and is accommodated in the actuator housing 11. The actuator 20 is capable of outputting torque as a driving force when energized. The ECU controls the energization of the actuator 20 and controls the operation of the actuator 20. The actuator housing 11 is provided with a reducer made up of a plurality of gears (not shown). The reducer is capable of reducing the torque of the actuator 20 and outputting it from a shaft member 36. The shaft member 36 is provided on a rotation axis Ax2 and is supported by the actuator housing 11 so as to be rotatable about the rotation axis Ax2.
[0027] The lever 40 has a lever main body 41, a lever one end 42, a lever other end 43, etc. The lever main body 41 is formed in a rod shape from, for example, metal, etc. The lever one end 42 is connected to one end of the lever main body 41 and is formed integrally with the lever main body 41. The lever other end 43 is connected to the other end of the lever main body 41 and is formed integrally with the lever main body 41. The lever other end 43 is formed to be approximately perpendicular to the lever main body 41. The lever other end 43 is provided to be parallel to the y-axis.
[0028] The lever 40 is provided such that one end 42 of the lever is connected to the shaft member 36. As a result, the lever 40 is rotatably supported by the actuator housing 11 so as to rotate around the rotation axis Ax2 together with the shaft member 36. The lever 40 rotates around the rotation axis Ax2 by the driving force from the actuator 20 output from the shaft member 36.
[0029] 1, reaction force applying device 10 is provided so that the outer peripheral wall of lever other end 43 can abut against the surface of arm 80 of accelerator device 60 on the side opposite floor panel 2, and can be separated from the surface of arm 80 on the side opposite floor panel 2. As a result, reaction force applying device 10 can apply reaction force F2 in response to a driver's depression force F1 to pedal 70 from lever 40, which rotates by a driving force from actuator 20, via arm 80.
[0030] Next, the configuration of the accelerator device 60 will be described in detail.
[0031] As shown in FIG. 4, the pedal 70 has a pedal hole 74 and a nut 75. The pedal base 72 is made of, for example, resin. Two pedal holes 74 are formed as hole-like recesses in the outer wall of the pedal base 72. The nut 75 is made of, for example, metal and is cylindrical, with a threaded groove formed in its inner peripheral wall. The nut 75 is provided in each of the two pedal holes 74 by, for example, heat press fitting. Here, the nut 75 is a component that constitutes a part of the pedal 70.
[0032] The arm 80 has an arm body 81, a connection portion 82, a reaction force receiving abutment surface 83, and a through-hole portion 84. The arm body 81 is formed by bending a long metal plate-shaped member at a predetermined location (see FIGS. 2 and 3). The connection portion 82 is formed at one end of the arm body 81. The reaction force receiving abutment surface 83 is formed in a flat shape on the side surface of the other end of the arm body 81 in the plate surface direction (see FIGS. 1 to 3 and 5).
[0033] Two through-holes 84 are provided in the connecting portion 82. The through-holes 84 are formed to penetrate the connecting portion 82 in the plate thickness direction. One of the two through-holes 84, that is, through-hole 841, is formed in an elongated hole shape (see FIG. 5). The other of the two through-holes 84, that is, through-hole 842, is formed in a cylindrical shape.
[0034] The fastening member 62 is a so-called screw made of, for example, metal. The fastening member 62 has a head 621 and a shaft 622 (see FIG. 4). The head 621 is formed in a substantially circular plate shape. The shaft 622 is formed to extend in the axial direction from the center of the head 621. A thread that can be screwed into the thread groove of the nut 75 is formed on the outer peripheral wall of the shaft 622.
[0035] This embodiment includes two fastening members 62. One of the two fastening members 62 passes through the through-hole portion 841 and is adapted to be screwed into one of the two nuts 75. The other of the two fastening members 62 passes through the through-hole portion 842 and is adapted to be screwed into the other of the two nuts 75.
[0036] The fastening member 62 can fix the arm 80 to the pedal 70 by sandwiching the connection portion 82 between the head portion 621 and the nut 75. The connection portion 82 is connected to the nut 75, which is part of the pedal 70.
[0037] <4> The positioning flat portion 91 is provided in the through-hole portion 841 .
[0038] The positioning flat portions 91 are formed in two on the inner wall of the through-hole portion 841 (see FIGS. 5 and 6). One of the two positioning flat portions 91, the positioning flat portion 911, is formed on one of the two opposing planar inner walls of the through-hole portion 841. The other of the two positioning flat portions 91, the positioning flat portion 912, is formed on the other of the two opposing planar inner walls of the through-hole portion 841. The positioning flat portion 911 and the positioning flat portion 912 are parallel to each other.
[0039] <2>The positioning flat portion 911 and the positioning flat portion 912 are parallel to the straight line L1 connecting the centers of two of the plurality of fastening members 62 (see FIG. 6).
[0040] As shown in FIG. 6, when the outer diameter of the shaft portion 622 of the fastening member 62 is R1, the inner diameter of the through-hole portion 84 is R2, the width in the short direction of the through-hole portion 841 is W1, and the width in the longitudinal direction of the through-hole portion 841 is W2, the fastening member 62 and the through-hole portion 842 are formed to satisfy, for example, the relationship of 1.001 < R2 / R1 < 1.1. Also, the fastening member 62 and the through-hole portion 841 are formed to satisfy, for example, the relationships of 1.001 < W1 / R1 < 1.1 and 1.01 < W2 / R1. Here, R2 = W1. Also, W1 is equal to the distance between the positioning flat portion 911 and the positioning flat portion 912.
[0041] Note that W2 is set to a size such that the shaft portion 622 can move relatively in the longitudinal direction of the through-hole portion 841 inside the through-hole portion 841.
[0042] The positioning flat portion 911 and the positioning flat portion 912 are parallel planes that can engage with the fastening member 62 as another member.
[0043] In this embodiment, when assembling the arm 80 to the pedal 70, the shaft portions 622 of the two fastening members 62 are inserted into the through-hole portions 841 and 842, and a portion of the shaft portion 622 is screwed into the nut 75. In this state, relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning plane portion 91 is restricted, while relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning plane portion 91 is permitted, making it possible to adjust the assembly position of the arm 80 relative to the pedal 70.
[0044] <3> The reaction force receiving abutment surface 83 is provided so as to be able to abut against the lever 40 of the reaction force applying device 10, and receives a reaction force from the lever 40 in response to the pedaling force of the driver. More specifically, the reaction force receiving abutment surface 83 is able to abut against the outer peripheral wall of the other end 43 of the lever 40.
[0045] The positioning flat surface portion 911 and the positioning flat surface portion 912 are parallel to the reaction force receiving contact surface 83 (see FIGS. 5 and 6).
[0046] Therefore, when assembling the arm 80 to the pedal 70, even if the assembly position of the arm 80 relative to the pedal 70 shifts in a direction parallel to the positioning plane portion 91, variation in the relative position between the other end portion 43 of the lever and the reaction force receiving abutment surface 83 can be suppressed.
[0047] As explained above, <1> In this embodiment, the fastening member 62 can fix the arm 80 to the pedal 70. The positioning portion 90 can restrict relative movement between the arm 80 and the pedal 70. The arm 80 has a connection portion 82 that connects to the pedal 70, and a through-hole portion 84 provided in the connection portion 82 so that the fastening member 62 can be inserted therethrough.
[0048] The positioning portion 90 has two parallel positioning flat portions 91 that can engage with the fastening member 62, which serves as another member. Therefore, engagement between the two positioning flat portions 91 and the fastening member 62 allows relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning flat portions 91, while restricting relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning flat portions 91. This ensures ease of assembly by allowing relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning flat portions 91, while restricting relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning flat portions 91, thereby reducing variation in assembly position. This makes it possible to both ensure ease of assembly of the components and reduce variation in assembly position. This reduces variation in the reaction force imparted to the arm 80 by the reaction force imparting device 10.
[0049] Also, <2> In this embodiment, the positioning flat surface portion 911 and the positioning flat surface portion 912 are parallel to a straight line L1 that connects the centers of two of the multiple fastening members 62.
[0050] Therefore, the fastening member 62 can be used as another member that is an engagement target of the positioning flat portion 91. This makes it possible to reduce the number of parts compared to when another member that is an engagement target of the positioning flat portion 91 is separately provided.
[0051] Also, <3> In this embodiment, the reaction force receiving abutment surface 83 is provided so as to be able to abut against the lever 40 of the reaction force application device 10, and receives a reaction force against the pedaling force of the driver from the lever 40. The positioning flat portion 91 is parallel to the reaction force receiving abutment surface 83.
[0052] Therefore, even if the assembly position of the arm 80 relative to the pedal 70 is shifted in a direction parallel to the positioning flat surface 91 when the arm 80 is assembled to the pedal 70, it is possible to prevent variation in the relative position between the other end portion 43 of the lever and the reaction force receiving abutment surface 83. This makes it possible to prevent variation in the reaction force applied to the arm 80 from the reaction force applying device 10.
[0053] Also, <4> In this embodiment, the positioning flat portion 91 is provided in the through-hole portion 841 .
[0054] Therefore, the fastening member 62 can be used as another member to be engaged by the positioning flat portion 91 .
[0055] (Second embodiment) An accelerator device according to a second embodiment and a part thereof are shown in Figures 7 to 9. The second embodiment differs from the first embodiment in the configurations of a pedal 70 and an arm 80.
[0056] <5> In this embodiment, the positioning portion 90 has a positioning recess 92 provided in the pedal 70 and a positioning protrusion 93 provided in the connection portion 82 and capable of fitting into the positioning recess 92. The positioning flat portion 91 is provided in the positioning recess 92.
[0057] More specifically, two positioning recesses 92 are provided in the pedal base 72. One of the two positioning recesses 92, a positioning recess 921, is formed so as to be recessed in a hole-like shape from the outer wall of the pedal base 72 on one side in the direction perpendicular to a line L2 that passes through the centers of the two pedal holes 74 (see FIG. 8). The other of the two positioning recesses 92, a positioning recess 922, is formed so as to be recessed in a hole-like shape from the outer wall of the pedal base 72 on the other side in the direction perpendicular to the line L2.
[0058] The positioning recess 921 is formed in the shape of an elongated hole. The positioning recess 922 is formed in the shape of a cylinder. Two positioning flat surfaces 91 are formed on the inner wall of the positioning recess 921 (see FIG. 8). One of the two positioning flat surfaces 91, namely, positioning flat surface 911, is formed on one of the two opposing planar inner walls of the positioning recess 921. The other of the two positioning flat surfaces 91, namely, positioning flat surface 912, is formed on the other of the two opposing planar inner walls of the positioning recess 921. The positioning flat surface 911 and the positioning flat surface 912 are parallel to each other.
[0059] Two positioning protrusions 93 are provided on the connecting portion 82 (see FIG. 9). One of the two positioning protrusions 93, a positioning protrusion 931, is formed so as to protrude in a cylindrical shape from the end face of the connecting portion 82 on one side in the direction perpendicular to a line L3 that passes through the centers of the through-holes 841 and 842. The other of the two positioning protrusions 93, a positioning protrusion 932, is formed so as to protrude in a cylindrical shape from the end face of the connecting portion 82 on the other side in the direction perpendicular to the line L3.
[0060] In addition, at positions corresponding to the positioning protrusions 931 and 932 on the end face opposite the positioning protrusion 93 of the connecting portion 82, recesses 933 and 934 are formed that are recessed to correspond to the shapes of the positioning protrusions 931 and 932 (see Figure 8).
[0061] The positioning protrusions 931 and 932 are formed so as to be able to fit into the positioning recesses 921 and 922, respectively. Here, the positioning flat surface 911 and the positioning flat surface 912 are able to engage with the outer peripheral wall of the positioning protrusion 931 formed on the arm 80, which is another member.
[0062] In this embodiment, the through-hole portion 841 is formed in a cylindrical shape. The positioning flat portion 911 and the positioning flat portion 912 are not parallel to the reaction force receiving contact surface 83.
[0063] In this embodiment, when assembling the arm 80 to the pedal 70, with the positioning protrusions 931 and 932 inserted into the positioning recesses 921 and 922, respectively, the relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning flat surface 91 is restricted, while the relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning flat surface 91 is permitted, making it possible to adjust the assembly position of the arm 80 relative to the pedal 70.
[0064] As explained above, <5> In this embodiment, the positioning portion 90 has a positioning recess 92 provided in the pedal 70 and a positioning protrusion 93 provided in the connection portion 82 and capable of fitting into the positioning recess 92. The positioning flat portion 91 is provided in the positioning recess 92.
[0065] Therefore, the arm 80 can be fixed to the pedal 70 by the fastening member 62 while the positioning portion 90 restricts the relative movement between the arm 80 and the pedal 70 .
[0066] (Third embodiment) An accelerator device according to a third embodiment and a part thereof are shown in Figures 10 to 12. The third embodiment differs from the first embodiment in the configurations of a pedal 70 and an arm 80.
[0067] <5> In this embodiment, the positioning portion 90 has a positioning recess 94 provided in the pedal 70 and a positioning protrusion 95 provided in the connection portion 82 and capable of fitting into the positioning recess 94. The positioning flat portion 941 and the positioning flat portion 942 are provided in the positioning recess 94. The positioning flat portion 951 and the positioning flat portion 952 are provided in the positioning protrusion 95.
[0068] More specifically, one positioning recess 94 is provided in the pedal base 72. The positioning recess 94 is formed so as to recess like a hole from the outer wall of the pedal base 72. The positioning recess 94 is formed in the shape of an elongated hole.
[0069] The positioning flat surface 941 is formed on one of two opposing planar inner walls of the positioning recess 94. The positioning flat surface 942 is formed on the other of the two opposing planar inner walls of the positioning recess 94. The positioning flat surface 941 and the positioning flat surface 942 are parallel to each other.
[0070] The two pedal holes 74 are formed in the bottom surface of the positioning recess 94. The nuts 75 are provided in the pedal holes 74.
[0071] One positioning protrusion 95 is provided on the connecting portion 82 (see FIG. 12). The positioning protrusion 95 is formed so as to protrude from the end face of the connecting portion 82. The positioning protrusion 95 is formed in an oval shape so that the cross-sectional shape perpendicular to the protruding direction corresponds to the cross-sectional shape perpendicular to the recessed direction of the positioning recess 94.
[0072] The positioning flat portion 951 is formed on one of two parallel planar outer walls of the positioning protrusion 95. The positioning flat portion 952 is formed on the other of the two parallel planar outer walls of the positioning protrusion 95.
[0073] Incidentally, a recess 953 that is recessed to correspond to the shape of the positioning protrusion 95 is formed at a position corresponding to the positioning protrusion 95 on the end face of the connecting portion 82 opposite to the positioning protrusion 95 .
[0074] The through-holes 841 and 842 are formed to connect the bottom surface of the recess 953 and the end surface of the positioning protrusion 95 .
[0075] The positioning protrusion 95 is formed so that it can fit into the positioning recess 94. Here, the positioning flat surface 941 and the positioning flat surface 951 can face each other and come into contact with each other. Furthermore, the positioning flat surface 942 and the positioning flat surface 952 can face each other and come into contact with each other. In other words, the positioning flat surface 941 and the positioning flat surface 942 can engage with the positioning flat surface 951 and the positioning flat surface 952 formed on the arm 80, which is another member.
[0076] The longitudinal width of the positioning recess 94 is greater than the longitudinal width of the positioning protrusion 95. Therefore, the positioning protrusion 95 is movable relative to the positioning recess 94 in a direction parallel to the positioning flat portion 941 and the positioning flat portion 942.
[0077] In this embodiment, the through-hole 841 is formed in a cylindrical shape. The positioning flat surface 941, the positioning flat surface 942, the positioning flat surface 951, and the positioning flat surface 952 are not parallel to the reaction force receiving contact surface 83.
[0078] In this embodiment, when assembling the arm 80 to the pedal 70, with the positioning protrusion 95 inserted into the positioning recess 94, relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning flat portions 941, 942, 951, and 952 is restricted, while relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning flat portions 941, 942, 951, and 952 is permitted, making it possible to adjust the assembly position of the arm 80 relative to the pedal 70.
[0079] As explained above, <5> In this embodiment, the positioning portion 90 has a positioning recess 94 provided in the pedal 70 and a positioning protrusion 95 provided in the connection portion 82 and capable of fitting into the positioning recess 94. The positioning flat portion 941 and the positioning flat portion 942 are provided in the positioning recess 94. The positioning flat portion 951 and the positioning flat portion 952 are provided in the positioning protrusion 95.
[0080] Therefore, the arm 80 can be fixed to the pedal 70 by the fastening member 62 while the positioning portion 90 restricts the relative movement between the arm 80 and the pedal 70 .
[0081] (Fourth embodiment) A part of an accelerator device according to the fourth embodiment is shown in Figures 13 and 14. The fourth embodiment differs from the second embodiment in the configuration of the arm 80 and the like.
[0082] In this embodiment, through-holes 843 and 844 are formed in the connecting portion 82 at the positions of the positioning protrusions 931, 932, recesses 933, and recesses 934 shown in the fourth embodiment. The through-holes 843 and 844 are formed in a cylindrical shape so as to penetrate the connecting portion 82 in the plate thickness direction.
[0083] In this embodiment, when assembling the arm 80 to the pedal 70, the two cylindrical positioning members 96 are inserted into the through-holes 843 and 844, respectively, and the positioning protrusions 961 formed on one end of the positioning members 96 are fitted into the positioning recesses 921 and 922 (see FIG. 14). Here, the positioning flat surfaces 911 and 912 are engageable with the outer peripheral wall of the positioning protrusions 961 formed on the positioning member 96, which is another member.
[0084] In this embodiment, when assembling the arm 80 to the pedal 70, with the positioning protrusions 961 of the two positioning members 96 inserted into the positioning recesses 921 and 922, respectively, relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning flat surface 91 is restricted, while relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning flat surface 91 is permitted, making it possible to adjust the assembly position of the arm 80 relative to the pedal 70.
[0085] After the arm 80 is attached to the pedal 70 , the positioning member 96 may be left inserted in the positioning recesses 921 and 922 , or may be removed from the positioning recesses 921 and 922 .
[0086] (Fifth embodiment) A part of an accelerator device according to a fifth embodiment is shown in Figures 15 and 16. The fifth embodiment differs from the first embodiment in the configuration of a pedal 70 and the like.
[0087] In this embodiment, the nut 75 has a nut body 751 and a nut extension tubular portion 752. The nut body 751 is formed in a cylindrical shape. The nut extension tubular portion 752 is formed integrally with the nut body 751 so as to protrude in a cylindrical shape from the inner edge portion of one axial end face of the nut body 751. The outer diameter of the nut extension tubular portion 752 is smaller than the outer diameter of the nut body 751.
[0088] The outer diameter of the nut extension tube portion 752 is slightly smaller than the width of the through hole portion 841 in the short direction and smaller than the width of the through hole portion 841 in the long direction.
[0089] The positioning flat surface portion 911 and the positioning flat surface portion 912 are engageable with the outer peripheral wall of the nut extension tube portion 752 of the nut 75 as another member.
[0090] In this embodiment, when assembling the arm 80 to the pedal 70, with the nut extension tube portions 752 of the two nuts 75 inserted into the through-hole portions 841 and 842, respectively, the relative movement between the arm 80 and the pedal 70 in a direction perpendicular to the positioning flat surface 91 is restricted, while the relative movement between the arm 80 and the pedal 70 in a direction parallel to the positioning flat surface 91 is permitted, making it possible to adjust the assembly position of the arm 80 relative to the pedal 70.
[0091] (Other embodiments) In the above-described embodiment, the arm is fixed to the pedal by two fastening members, but in other embodiments, the arm may be fixed to the pedal by one or three or more fastening members.
