Description

Technical Field

[0001] The present disclosure relates to a pedal device for a vehicle. Background Art

[0002] The pedal device for a vehicle disclosed in Japanese Patent Publication No. 2015-33925 includes a brake pedal and an accelerator pedal. The brake pedal is rotatably supported on a dash panel. The brake pedal has a brake pedal pad stepped on by a driver. A base member is fixed to a bracket fixed to a floor, and the lower end of the accelerator pedal pad is rotatably supported on the base member. That is, the accelerator pedal is an organ-type accelerator pedal.

[0003] When fixing the base member to the bracket, usually, the base member is first temporarily fixed to the bracket using two bolts inserted into two through holes formed in the base member. That is, the threaded portions of the two bolts are inserted into the female threaded holes of the bracket and the heads of the bolts are separated from the base member. Next, the insertion amount of each bolt into the female threaded hole is increased, and the heads of the bolts are pressed against the base member. Thus, the base member is fixed to the bracket by the two bolts.

[0004] In the technology described in Japanese Patent Application Publication No. 2015-33925, a gap is formed between the two through holes and each bolt. Therefore, when the base member is temporarily fixed to the bracket, the base member can move relative to the bracket within the range of the above gap. Therefore, when the base member is fixed to the bracket, the relative positions of the base member and the accelerator pedal pad with respect to the bracket may deviate from the designed position. Summary of the invention

[0005] The present disclosure takes the above-mentioned facts into consideration and aims to provide a vehicle pedal device capable of fixing a base member rotatably supporting an accelerator pedal pad to a supporting member in a manner that prevents a predetermined portion of an accelerator pedal pad of an organ-type accelerator pedal from greatly deviating from a designed position.

[0006] The pedal device for a vehicle of the first scheme of the present disclosure comprises: a base member supported by a supporting member, the supporting member being at least one of a panel constituting an inner wall of an interior space of a vehicle and a bracket fixed to the panel; and an accelerator pedal pad of an organ-type accelerator pedal supported by the base member in a rotatable manner, a reference hole being formed in a member of one of the supporting member and the base member, at least one fixing through-hole being formed in the base member, a reference shaft member being inserted into the reference hole while forming a specified first gap with an inner circumferential surface of the reference hole and intersecting the accelerator pedal pad along an extension line of its own extension direction, being supported by a member of the other of the supporting member and the base member, a fixing shaft member being inserted into the fixing through-hole while forming a second gap larger than the first gap with the inner circumferential surface of the fixing through-hole, thereby fixing the base member to the supporting member.

[0007] In a vehicle pedal device of a first embodiment of the present disclosure, a reference hole is formed in one of a supporting member and a base member that rotatably supports an accelerator pedal pad, and the supporting member is at least one of a panel that constitutes an inner wall of an interior space of a vehicle and a bracket fixed to the panel. Furthermore, a reference shaft member is supported by the other of the supporting member and the base member. The reference shaft member is inserted into the reference hole while forming a first gap with the inner peripheral surface of the reference hole.

[0008] The first gap is smaller than the second gap formed between at least one fixing through hole formed in the base member and the fixing shaft member. Therefore, when the base member is not fixed to the support member by the fixing shaft member, the base member can rotate relative to the support member within the range of the second gap with the reference shaft member inserted into the reference hole as the rotation center. Therefore, when a plurality of base members are fixed to a plurality of support members respectively by using the fixing shaft member, there is a possibility that the relative positions of the accelerator pedal pads relative to the support members may be uneven.

[0009] However, the extension line along the axis of the reference shaft member intersects the accelerator pedal pad. Therefore, even if the base member is relatively rotated relative to the support member within the range of the second gap, the position of the portion of the accelerator pedal pad that intersects the extension line does not substantially change. Therefore, as long as the reference shaft member is supported on the other member in such a manner that the specified portion of the accelerator pedal pad intersects the extension line, the position of the specified portion will not deviate significantly from the designed position. Therefore, the base member can be fixed to the support member in such a manner that the driver can easily operate the accelerator pedal.

[0010] A vehicle pedal device according to a second aspect of the present disclosure includes a suspended brake pedal having a brake pedal pad rotatably supported by the panel, wherein the extension line overlaps the brake pedal pad when viewed in the vehicle width direction.

[0011] In the second aspect of the present disclosure, when viewed in the vehicle width direction, the extension line of the reference shaft member overlaps with the brake pedal pad. Therefore, the driver can easily operate the accelerator pedal pad and the brake pedal pad with one foot.

[0012] In the vehicle pedal device according to the third aspect of the present disclosure, the reference shaft member is a reference pin inserted into the reference hole.

[0013] In the third aspect of the present disclosure, compared with a case where the reference axis member is a bolt or a rivet, the mounting operation of the base member to the support member using the reference axis member can be performed more easily.

[0014] In the vehicle pedal device according to the fourth aspect of the present disclosure, the other member and the reference pin are fixed to each other.

[0015] In the fourth aspect of the present disclosure, the work of supporting the reference pin on the other member is not required, so the work of fixing the base member to the support member becomes easy.

[0016] In the vehicle pedal device according to a fifth aspect of the present disclosure, the other member is the base member, and the base member and the reference pin are integrally molded products made of resin.

[0017] In the fifth aspect of the present disclosure, since the base member and the reference pin are integrally molded products made of resin, the number of components of the vehicle pedal device can be reduced.

[0018] In the vehicle pedal device of the sixth scheme of the present disclosure, the reference pin is supported on the base member, the reference hole formed in the supporting member is a through hole, the reference pin can penetrate the reference hole from the base member side and has an anti-slip claw located on the outer peripheral side of the reference hole and opposite to the base member when the reference hole is penetrated.

[0019] In the sixth aspect of the present disclosure, when the reference pin passes through the reference hole from the base member side, the anti-dropout claw is located at the outer peripheral side of the reference hole and opposite to the base member. Therefore, the reference pin supported by the base member can be easily inserted into the reference hole in a manner that does not fall out of the reference hole formed in the supporting member.

[0020] In the vehicle pedal device according to a seventh aspect of the present disclosure, the fixing through hole is an elongated hole, and a longitudinal direction of the elongated hole is a direction along a circumferential direction centered on the reference shaft member.

[0021] In the seventh scheme of the present disclosure, a second gap along the circumferential direction centered on the reference shaft member can be formed between the fixed through hole as a long hole and the fixed shaft member. When such a second gap is formed, it is not necessary to set the gap formed between the fixed through hole and the fixed shaft member in the direction orthogonal to the circumferential direction to the same size as the second gap. That is, the gap in the direction orthogonal to the circumferential direction can be made smaller than the second gap. Therefore, the area of ​​the fixed through hole as a long hole can be made smaller than the area of ​​the fixed through hole as a circular hole. Therefore, compared with the case where the fixed through hole is circular, the mechanical strength of the base member can be improved.

[0022] In the vehicle pedal device of the eighth scheme of the present disclosure, it has: a movable body, which controls the working state of the driving source of the vehicle by moving; and a pressing member, which is arranged on the surface of the base member side at a specified position of the accelerator pedal pad in a manner extending toward the base member side, and is linked with the rotation of the accelerator pedal pad to move the movable body, and the extension line intersects the specified position.

[0023] In the eighth aspect of the present disclosure, since the predetermined portion of the accelerator pedal pad where the pressing member is provided intersects with the extension line of the reference shaft member, the position of the predetermined portion does not deviate significantly from the designed position.

[0024] Furthermore, if the driver applies force to a predetermined portion of the accelerator pedal pad with his foot, the force is efficiently transmitted from the predetermined portion to the moving body. Therefore, the driver can control the operating state of the drive source with a small force by pressing the predetermined portion with his foot.

[0025] As described above, the vehicle pedal device of the present disclosure has an excellent effect of being able to fix the base member that rotatably supports the accelerator pedal pad to the support member so as to prevent the position of a predetermined portion of the accelerator pedal pad of the organ-type accelerator pedal from greatly deviating from the designed position.

[0047] Below, while referring to the attached Figure 1 The embodiment of the vehicle pedal device 10 disclosed in the present invention is described. It should be noted that the arrow UP recorded in each figure indicates the upper side of the vehicle vertical direction, the arrow FR indicates the front side of the vehicle front-back direction, and the arrow LH indicates the left side of the vehicle left-right direction (vehicle width direction). The up-down direction, front-back direction, and left-right direction in the following description respectively mean the vehicle up-down direction, the vehicle front-back direction, and the vehicle left-right direction.

[0048] like Figure 1 As shown, a part of the metal body shell constituting the vehicle body of the vehicle equipped with the vehicle pedal device 10 (hereinafter referred to as the pedal device 10) is constituted by a dash panel (panel) 14 made of a metal plate. An engine room (not shown) is formed in front of the dash panel 14, and a vehicle compartment 16 is formed behind the dash panel 14. A pedal bracket 18 is fixed to the dash panel 14.

[0049] A suspended brake pedal 20 is supported on the pedal bracket 18. The brake pedal 20 includes an elongated arm 22 and a brake pedal pad 24 provided at the lower end of the arm 22. The upper end of the arm 22 is rotatably supported on the pedal bracket 18 via a rotation shaft 26 extending in the vehicle width direction. The brake pedal 20 is moved by a force applying unit (not shown) to the brake pedal 20. Figure 1 The vehicle is provided with a brake pedal 20 which is rotated counterclockwise to apply force. Figure 1 The brake pedal 20 is located at the initial position shown in the figure. Therefore, if the driver removes his foot from the brake pedal pad 24, the brake pedal 20 is located at the initial position. It should be noted that in this specification, "foot" refers to a part of the body located at the front end side of the ankle. In addition, when the driver wears shoes, "foot" refers to the shoes.

[0050] When the driver steps forward on the brake pedal pad 24 with his foot, the brake booster (not shown) works, and braking force is applied to each wheel (not shown) from each brake device (not shown) provided on the vehicle. When the driver removes his foot from the brake pedal pad 24, the brake pedal 20 moves back to the initial position, and the braking force applied to each wheel from each brake device disappears.

[0051] A portion of the vehicle body shell is formed by a floor (panel) 30 formed of a metal plate. The front end of the floor 30 is connected to the lower end of the dash panel 14. Figure 1 As shown, the floor panel 30 has a base portion 30A having a substantially trapezoidal cross-sectional shape perpendicular to the vehicle width direction. Figure 1 , Figure 6 and Figure 7 As shown, a circular reference hole 30A2 is formed in an upper plate portion 30A1 constituting an upper end portion of the base portion 30A.

[0052] like Figure 1 As shown in FIG. 1 , a metal bracket 34 is fixed to the upper surface of the floor 30. The bracket 34 is not a flat plate, but has a plurality of steps. The front end of the bracket 34 is fixed to the upper plate portion 30A1, and the rear end of the bracket 34 is fixed to a portion of the floor 30 located further back than the pedestal portion 30A. Figure 1 , Figure 6 and Figure 7 As shown, a reference hole 34A is formed at the front end of the bracket 34. The reference hole 34A is a circular hole having the same diameter and the same axis as the reference hole 30A2 of the base portion 30A. The inner diameter of the reference hole 30A2 and the reference hole 34A is D1.

[0053] like Figure 1 , Fig. 9 and Fig.10As shown in FIG. 1 , two through holes 34B and 34C arranged in the front-rear direction are formed at the left edge of the bracket 34. The through holes 34B and 34C are located on the left side and rear side (lower side) of the reference hole 34A. In addition, two weld nuts 38 and 40 coaxial with the through holes 34B and 34C are fixed to the lower surface of the bracket 34. The floor 30, the bracket 34, and the weld nuts 38 and 40 are components of the support member 36.

[0054] An organ-type accelerator pedal device 50 is mounted on the bracket 34. Figure 1 to Figure 5 As shown, the accelerator pedal device 50 includes a base member 52 , a reference pin (reference shaft member) 60 , an accelerator pedal pad 68 (hereinafter referred to as the pedal pad 68 ), a fixing bolt 78 , and a fixing bolt 80 .

[0055] The base member 52 is an integrally molded product made of resin and includes a support portion 54 , a fixed portion 58 , a housing portion 59 , and a reference pin 60 .

[0056] A support portion 54 is provided at a rear end portion (lower end portion) of the base member 52. A lower end portion of a pedal pad 68 is connected to the support portion 54 so as to be rotatable about an axis in the left-right direction.

[0057] A fixed portion 58 is provided on the left side of the base member 52. Figure 4 As shown in FIG. 1 , two protrusions 58A and 58B are provided on the lower surface of the fixed portion 58 and are arranged in the front-rear direction. Figure 2 As shown, two recesses 62A and 64A are formed at positions corresponding to the protrusions 58A and 58B on the upper surface of the fixed portion 58. The cross-sectional shape of the recesses 62A and 64A is circular. The bottom surfaces of the recesses 62A and 64A are provided with fixing through holes 62B and 64B that penetrate the bottoms of the protrusions 58A and 58B. Figure 2 to Figure 5 As shown, the fixing through holes 62B and 64B are both circular, and the inner diameters of the fixing through holes 62B and 64B are the same. Fig. 9 As shown, the inner diameter D2 of the fixing through holes 62B and 64B is smaller than the inner diameters of the through holes 34B and 34C and the recesses 62A and 64A. Furthermore, the inner diameter D2 of the fixing through holes 62B and 64B is larger than the inner diameter D1 of the reference holes 30A2 and 34A provided in the upper plate portion 30A1 and the bracket 34.

[0058] The base member 52 has a hollow housing portion 59 located on the right side of the fixed portion 58. The upper surface of the housing portion 59 is located above the upper surface of the fixed portion 58. Figure 1 and Fig.12 As shown in FIG. 5 , a through hole 59A is formed on the upper surface of the housing portion 59 and passes through the top plate portion of the housing portion 59. Fig.12As shown, a spring 59B, a rotating body (moving body) 59C, and an encoder (not shown) for detecting the rotation angle of the rotating body 59C are provided in the internal space of the housing 59. The rotating body 59C is rotatable around its own axis 59X.

[0059] like Figure 4 and Figure 5 As shown, the upper end of the reference pin 60 is supported at the front end of the lower surface of the housing portion 59. Figure 6 and Figure 7 As shown in FIG. 1 , the reference pin 60 has a main body portion 60A and an elastic deformation portion 60B. Figure 2 , Figure 4 and Figure 5 In the figure, for convenience, the shape of the reference pin 60 is simplified and depicted. The main body 60A and the elastic deformation part 60B are connected at the upper ends of the two. The lower end surface of the main body 60A is a tapered surface 60A1 centered on the central axis 60X of the reference pin 60. The elastic deformation part 60B can be elastically deformed in the radial direction of the reference pin 60. An anti-drop claw 60B1 is provided at the lower end of the elastic deformation part 60B. When the elastic deformation part 60B is in a free state ( Figure 6 When the elastic deformation portion 60B is in a free state, the outer diameter of the reference pin 60 at the position of the upper end of the anti-detachment claw 60B1 of the reference pin 60 is D4. The outer diameter D3 is smaller than the inner diameter D1 of the reference holes 30A2 and 34A provided in the upper plate portion 30A1 and the bracket 34. On the other hand, the outer diameter D4 is larger than the inner diameter D1 and the outer diameter D3 of the reference holes 30A2 and 34A.

[0060] As described above, the lower end of the plate-shaped pedal pad 68 is rotatably connected to the support portion 54. Figure 1 and Fig.12 The initial position shown is different from the position located at the front side of the initial position. Fig.12 The cam is rotated between the maximum depressed positions shown by the imaginary line. Figure 1 and Fig.12 In the embodiment, the pedal pad 68 is mechanically restricted from rotating clockwise from the initial position and from rotating counterclockwise from the maximum depression position. The pedal pad 68 is a member stepped on by the driver's foot. A depression reference portion 68X ( Figure 2 In addition, if Figure 2 , Figure 4 , Figure 5 and Fig.12As shown, one end of a pressing member 76 is connected to the lower surface of the depression reference portion 68X. The depression reference portion 68X is a portion of the accelerator pedal (BOF: ball of foot) determined by the Society of Automotive Engineers (SAE) to be pressed by the ball of the thumb of a driver of average physique.

[0061] like Fig.12 As shown, the lower part of the pressing member 76 enters the internal space of the housing portion 59 through the through hole 59A. Moreover, the lower end of the pressing member 76 is connected to the rotating body 59C inside the housing portion 59. Moreover, the elastically deformed spring 59B always applies force to the rotating body 59C in rotation. The rotation force direction of the spring 59B is the direction in which the pedal pad 68 is pressed toward the initial position side via the rotating body 59C and the pressing member 76. If the pedal pad 68 rotates from the initial position to the maximum stepped position side, the rotating body 59C rotates and the elastic deformation amount of the spring 59B increases. Then, the encoder detects the rotation amount of the rotating body 59C. That is, the encoder detects the stepped amount of the pedal pad 68. Then, the encoder sends a signal corresponding to the detected amount to the throttle actuator of the engine (drive source) (not shown) arranged in the engine room. Therefore, the working state of the engine is controlled by moving the pedal pad 68 and the pressing member 76. It should be noted that the structure and operation of the mechanism including the pedal pad 68, the pressing member 76, the spring 59B, the rotating body 59C and the encoder are described in, for example, Japanese Patent Publication No. 2019-96253. Therefore, the description of the structure and operation in Japanese Patent Publication No. 2019-96253 is incorporated into the present application specification by referring to Japanese Patent Publication No. 2019-96253.

[0062] When fixing the base member 52 to the support member 36 (the floor 30 and the bracket 34), first Figure 6 As shown, the reference pin 60 located at the upper side (rear side) of the bracket 34 is made coaxial with the reference hole 34A of the bracket 34 and the reference hole 30A2 of the pedestal 30A. Next, the reference pin 60 is moved to the lower side (front side) and close to the reference holes 34A and 30A2. As described above, the outer diameter D4 at the position of the upper end of the anti-detachment claw 60B1 of the reference pin 60 when the elastic deformation part 60B is in a free state is larger than the inner diameter D1 of the reference hole 30A2 and the reference hole 34A. However, if the reference pin 60 is further moved to the lower side (front side) under the state that a part of the tapered surface 60A1 and a part of the anti-detachment claw 60B1 are in contact with the peripheral portion of the reference hole 34A of the bracket 34, the elastic deformation part 60B is elastically deformed in a manner close to the main body 60A. Therefore, the main body 60A and the elastic deformation portion 60B (the anti-separation claw 60B1) are inserted into the reference hole 30A2 and the reference hole 34A. Figure 7As shown, if the anti-separation claw 60B1 moves to the lower side of the upper plate portion 30A1, the elastic deformation portion 60B returns to a free state, and the upper end of the anti-separation claw 60B1 located on the outer peripheral side of the reference holes 30A2 and 34A faces the lower surface of the upper plate portion 30A1. Moreover, the lower surface of the fixed portion 58 contacts the upper surface of the bracket 34.

[0063] As described above, the outer diameter D3 of the reference pin 60 is smaller than the inner diameter D1 of the reference holes 30A2 and 34A. Figure 8 As shown, a gap is formed between the reference holes 30A2, 34A and the portion of the reference pin 60 that is located above the anti-slip claw 60B1. For example, when the reference holes 30A2, 34A and the reference pin 60 are approximately coaxial with each other, two gaps CL1-a and CL1-b are formed between the reference holes 30A2, 34A and the reference pin 60. The sum of the two gaps CL1-a and CL1-b, i.e., the first gap CL1, is the gap between the reference holes 30A2, 34A and the reference pin 60. However, the first gap CL1 is very small. Therefore, the reference pin 60 is not substantially loose relative to the reference holes 30A2, 34A. It should be noted that in Figure 8 In order to make the present invention easier to understand, the first gap CL1 is exaggeratedly depicted.

[0064] If the front portion of the base member 52 is mounted on the upper surface of the bracket 34, Figure 1 As shown in FIG. 1 , the lower surfaces of the protrusions 58A and 58B are in contact with two locations on the upper surface of the bracket 34. When the base member 52 is rotated relative to the bracket 34 with the reference pin 60 as the center in a state where the lower surfaces of the protrusions 58A and 58B are in contact with the upper surface of the bracket 34, the fixing through holes 62B and 64B are respectively opposite to the two through holes 34B and 34C of the bracket 34 (see FIG. 1 ). Fig. 9 ).

[0065] Next, use Fig. 9 and Fig.10 The fixing bolt (fixing shaft member) 78 and the fixing bolt (fixing shaft member) 80 shown fix the base member 52 to the support member 36 (the floor 30 and the bracket 34). The fixing bolt 78 and the fixing bolt 80 are both made of metal. The fixing bolt 78 and the fixing bolt 80 have heads 78A and 80A and shafts 78B and 80B, respectively. The shaft 78B of the fixing bolt 78 can be inserted from the upper side into the fixing through hole 62B and the through hole 34B of the bracket 34. The shaft 80B of the fixing bolt 80 can be inserted from the upper side into the fixing through hole 64B and the through hole 34C of the bracket 34.

[0066] The shaft portion 78B of the fixing bolt 78 is inserted into the fixing through hole 62B and the through hole 34B and screwed into the welding nut 38. Furthermore, the shaft portion 80B of the fixing bolt 80 is inserted into the fixing through hole 64B and the through hole 34C and screwed into the welding nut 40. However, at this time, if Fig. 9 As shown, the head 78A is moved upward away from the bottom surface of the recess 62A, and the head 80A is moved upward away from the bottom surface of the recess 64A.

[0067] like Fig. 9 As shown in FIG. 1 , the outer diameter D5 of the shaft portion 78B, 80B is smaller than the inner diameter D2 of the fixing through hole 62B, 64B. Therefore, a gap is formed between the fixing through hole 62B, 64B and the shaft portion 78B, 80B. Fig.11 As shown, when the fixing through hole 62B (fixing through hole 64B) and the shaft portion 78B (shaft portion 80B) are substantially coaxial with each other, two gaps CL2-a and CL2-b are formed between the fixing through hole 62B (fixing through hole 64B) and the shaft portion 78B (shaft portion 80B). The sum of the two gaps CL2-a and CL2-b, i.e., the second gap CL2, is the gap between the fixing through hole 62B (fixing through hole 64B) and the shaft portion 78B (shaft portion 80B). The second gap CL2 is larger than the first gap CL1. Therefore, the base member 52 (fixing through holes 62B, 64B) can be relatively close to the shaft portions 78B, 80B within the range of the second gap CL2 in the circumferential direction (centered on the reference pin 60) centered on the reference pin 60. Figure 2 and Fig.11 The arrow A indicates relative rotation in the circumferential direction).

[0068] like Fig.10 As shown, after the relative positions of the fixing through holes 62B and 64B with respect to the shaft portions 78B and 80B are determined, the shaft portions 78B and 80B are screwed onto the welding nuts 38 and 40 until the head portion 78A is pressed against the bottom surface of the recessed portion 62A and the head portion 80A is pressed against the bottom surface of the recessed portion 64A. Thus, the base member 52 is fixed to the support member 36 (the floor 30 and the bracket 34).

[0069] If the base member 52 is fixed to the support member 36, then Figure 2 As shown, the pedal pad 68 is located on the right side of the brake pedal pad 24 in a rear view (planar view). Moreover, the brake pedal pad 24 located in the initial position and the pedal pad 68 located in the initial position are viewed in the vehicle width direction. Figure 1 Furthermore, the extension line EL (refer to Figure 1 , Figure 2 and Fig.12 ) intersects with the stepping reference position 68X of the pedal pad 68. Figure 1 As shown, the extension line EL overlaps the brake pedal pad 24 when viewed in the vehicle width direction.

[0070] (Function and Effect)

[0071] Next, the operation and effects of this embodiment will be described.

[0072] In the pedal device 10 of this embodiment, the reference pin 60 is substantially not loose with respect to the reference holes 30A2 and 34A. Fig. 9 When the base member 52 is not fixed to the support member 36 by the fixing bolts 78 and 80 as shown, the base member 52 can rotate relative to the support member 36 within the range of the second gap CL2 about the reference pin 60 inserted into the reference holes 30A2 and 34A as the rotation center.

[0073] For example, if Fig.11 As shown in FIG. 1 , the base member 52 is fixed to the support member 36 by the fixing bolts 78 and 80 in a state where the shaft portion 78B (shaft portion 80B) and the fixing through hole 62B (fixing through hole 64B) are substantially coaxial, and the position of the pedal pad 68 becomes Figure 2 In addition, if the shaft portion 78B (shaft portion 80B) and the portion Pa (refer to Fig.11 ) is in contact with the base member 52 by fixing bolts 78 and 80 to the support member 36, and the pedal pad 68 is located Figure 2 In addition, if the shaft portion 78B (shaft portion 80B) and the portion Pb (refer to Fig.11 ) is in contact with the base member 52 by fixing bolts 78 and 80 to the support member 36, and the pedal pad 68 is located Figure 2 Therefore, when the plurality of base members 52 are fixed to the plurality of support members 36 , the relative positions of the pedal pads 68 with respect to the support members 36 may be uneven.

[0074] However, the extension line EL along the axis of the reference pin 60 intersects with the pedal pad 68 (the stepping reference portion 68X) that is not stepped on by the driver's foot. Therefore, even if the base member 52 is relatively rotated relative to the support member 36 within the range of the second gap CL2, the position of the portion (the stepping reference portion 68X) intersecting with the extension line EL of the reference pin 60 remains substantially unchanged. Therefore, as long as the reference pin 60 is set on the base member 52 in such a manner that the extension line EL passes through the stepping reference portion 68X of the pedal pad 68, the relative position of the stepping reference portion 68X relative to the support member 36 when the base member 52 is fixed to the support member 36 will not deviate significantly from the designed position. Therefore, the base member 52 can be fixed to the support member 36 in such a manner that the driver can easily operate the pedal pad 68.

[0075] on the other hand, Fig.13 In this modified example, the reference pin 60 is provided at the right end of the lower surface of the base member 52 and the reference hole 30A2 of the base portion 30A and the reference hole 34A of the bracket 34 (at Fig.13 This is different from the above-described embodiment in that the reference pin 60 is disposed at a position corresponding to the reference pin 60.

[0076] When the reference pin 60 is inserted into the reference hole 30A2, 34A and the base member 52 is fixed to the support member 36 by the fixing bolts 78, 80, the brake pedal pad 24 at the initial position and the pedal pad 68 at the initial position become Fig.13 Moreover, the extended line ELex extending along the axis of the reference pin 60 does not intersect the pedal pad 68 located at the initial position. Fig.13 As shown, a virtual surface obtained by extending the pedal pad 68 in the vehicle width direction (a virtual surface where the pedal pad 68 is located) is set as a virtual extension surface 68PL. In this case, the extension line ELex and the virtual extension surface 68PL intersect at an intersection point Pex located on the right side of the pedal pad 68. Fig.13 It is apparent that the intersection point Pex is away from the pedal pad 68 .

[0077] In the comparative example, when the head 78A and the head 80A are separated upward from the fixed portion 58, the fixing through holes 62B and 64B can be formed in the circumferential direction ( 100° to 100°) with respect to the shaft portions 78B and 80B within the range of the second gap CL2 with respect to the reference pin 60 (reference holes 30A2 and 34A). Fig.11 and Fig.13 Therefore, in the comparative example, regardless of the relative position of the base member 52 with respect to the support member 36, the position of the intersection point Pex hardly changes.

[0078] For example, Fig.11 As shown, the base member 52 is fixed to the support member 36 by the fixing bolts 78 and 80 in a state where the shaft portion 78B (shaft portion 80B) and the fixing through hole 62B (fixing through hole 64B) are substantially coaxial. In this case, the position of the pedal pad 68 of the comparative example becomes Fig.13 At this time, the stepping reference part 68X is located at Fig.13 The position indicated by the reference numeral 68Xt is the designed position of the stepping reference portion 68X in the comparative example.

[0079] On the other hand, if the portion Pc (see FIG. 1 ) between the shaft portion 78B (shaft portion 80B) and a portion of the inner peripheral surface of the fixing through hole 62B (fixing through hole 64B) is Fig.11 ) is in contact with the base member 52 by fixing bolts 78 and 80 to the support member 36, and the pedal pad 68 is located Fig.13 At this time, the stepping reference part 68X is located at the position indicated by the imaginary line (the position of the label 68C). Fig.13 The position shown by the label 68Xc.

[0080] In addition, if the portion Pd (see FIG. 1 ) between the shaft portion 78B (shaft portion 80B) and a portion of the inner peripheral surface of the fixing through hole 62B (fixing through hole 64B) is Fig.11 ) is in contact with the base member 52 by fixing bolts 78 and 80 to the support member 36, and the pedal pad 68 is located Fig.13 At this time, the stepping reference part 68X is located at the position indicated by the imaginary line (the position of the label 68D). Fig.13 The position shown by the label 68Xd.

[0081] Thus, in the comparative example as well, when the plurality of base members 52 are respectively fixed to the plurality of support members 36, there is a possibility that the relative positions of the pedal pads 68 with respect to the support members 36 may be uneven. Furthermore, in the comparative example, the relative position of the stepping reference portion 68X with respect to the support member 36 when the base member 52 is fixed to the support member 36 may be greatly deviated from the designed position. Therefore, it is not easy to fix the base member 52 to the support member 36 in a manner that allows the driver to easily operate the pedal pad 68.

[0082] Furthermore, in the pedal device 10 of the present embodiment, the extension line EL overlaps the brake pedal pad 24 that is not stepped on by the driver when viewed in the vehicle width direction. Therefore, the driver can easily operate the pedal pad 68 and the brake pedal pad 24 with one foot.

[0083] And the reference pin 60 that the pedal device 10 of the present embodiment possesses can be simply inserted into the reference hole 34A of the bracket 34 and the reference hole 30A2 of the pedestal portion 30A. And, because the reference pin 60 has the anti-separation claw 60B1, after the reference pin 60 is inserted into the reference hole 34A, 30A2, the reference pin 60 is almost impossible to accidentally come out from the reference hole 34A, 30A2.

[0084] Furthermore, the reference pin 60 is integrated with the housing 59. Therefore, compared with the case 59 and the reference pin 60 being manufactured separately and then fixed to the housing 59, the base member 52 of this embodiment has a small number of components and can be manufactured easily.

[0085] Furthermore, when the driver applies force to the depression reference portion 68X of the pedal pad 68, the force is efficiently transmitted from the depression reference portion 68X to the rotating body 59C. Therefore, the driver can control the operating state of the engine with a small force by pressing the depression reference portion 68X with his foot.

[0086] The pedal device 10 of the present embodiment is described above, but the pedal device 10 can be appropriately designed and modified within the scope of the present disclosure. It should be noted that in the following description, components with the same structure as the above embodiment are marked with the same reference numerals, and their detailed description is omitted.

[0087] <First Modification>

[0088] exist Fig.14 In the pedal device 10 of the first modified example shown, the fixing through holes 62C and 64C formed in the protrusions 58A and 58B are not circular holes but long holes. The length direction of the fixing through holes 62C and 64C is along the circumferential direction ( Fig.14 direction of arrow A).

[0089] In the first modified example, a second gap CL2 is formed along the circumferential direction (direction of arrow A) between the fixing through hole 62C (fixing through hole 64C) which is a long hole and the shaft portion 78B (shaft portion 80B). When such a second gap CL2 is formed, the gap CLC (see FIG. 1 ) in the direction orthogonal to the circumferential direction formed between the fixing through hole 62C (fixing through hole 64C) and the shaft portion 78B (shaft portion 80B) can be made Fig.14) is smaller than the second gap CL2. Therefore, the area of ​​the fixing through holes 62C and 64C as the long holes can be made smaller than the area of ​​the fixing through holes 62B and 64B as the circular holes. Therefore, when the fixing through holes 62C and 64C as the long holes are formed in the base member 52, the mechanical strength of the base member 52 is higher than when the fixing through holes 62B and 64B as the circular holes are formed in the base member 52.

[0090] <Second Modification>

[0091] exist Fig.15 A metal bracket 90 having a shape different from that of the bracket 34 is fixed to the upper plate portion 30A1 of the pedestal portion 30A of the pedal device 10 of the second modified example shown. The bracket 90 is a component of the support member 36. A mounting hole 90A is provided in the bracket 90. A reference pin (reference shaft member) 91 is mounted in the mounting hole 90A. The metal reference pin 91 has a cylindrical shaft portion 91A and a disc-shaped head portion 91B having a larger diameter than the shaft portion 91A. The shaft portion 91A is inserted into the mounting hole 90A from below, and the head portion 91B is fixed to the bracket 90. The upper portion of the shaft portion 91A protrudes upward from the bracket 90.

[0092] A circular reference hole 59D is formed on the lower surface of the housing 59. The shaft 91A of the reference pin 91 has a smaller diameter than the reference hole 59D. When the shaft 91A is inserted into the reference hole 59D, a first gap CL1 (at the inner circumference of the shaft 91A and the reference hole 59D) is formed between the shaft 91A and the inner circumference of the reference hole 59D. Fig.15 When the shaft portion 91A is inserted into the reference hole 59D, the lower surface of the housing portion 59 contacts the upper surface of the bracket 90, and the extension line EL of the reference pin 91 contacts the stepping reference position 68X of the pedal pad 68 (at Fig.15 (illustration omitted) cross.

[0093] Therefore, also in the second modification, the base member 52 can be fixed to the support member 36 (the floor 30 , the bracket 90 ) so as to prevent the relative position of the stepping reference portion 68X with respect to the support member 36 from being greatly deviated from the designed position.

[0094] <Third Modification>

[0095] Fig.16 The support member 36 of the pedal device 10 of the third modified example shown does not include the bracket 34. The upper plate portion 30A1 of the pedestal portion 30A is formed with a mounting hole 30A3. The shaft portion 91A of the reference pin 91 is inserted into the mounting hole 30A3 from below, and the head portion 91B is fixed to the upper plate portion 30A1. The upper portion of the shaft portion 91A protrudes upward from the upper plate portion 30A1.

[0096] A circular reference hole 59D is formed on the lower surface of the housing 59. When the shaft 91A is inserted into the reference hole 59D, a first gap CL1 (at the inner circumference of the shaft 91A and the reference hole 59D) is formed between the shaft 91A and the inner circumference of the reference hole 59D. Fig.16 When the shaft portion 91A is inserted into the reference hole 59D, the lower surface of the housing portion 59 contacts the upper surface of the upper plate portion 30A1, and the extension line EL of the reference pin 91 contacts the stepping reference portion 68X of the pedal pad 68 (at Fig.16 (illustration omitted) cross.

[0097] Therefore, also in the third modification, the base member 52 can be fixed to the support member 36 (floor 30 ) so as to prevent the relative position of the stepping reference portion 68X with respect to the support member 36 from being greatly deviated from the designed position.

[0098] <Fourth Modification>

[0099] Fig.17 and Fig.18 The basic structure of the pedal device 10 of the fourth modified example shown is the same as that of the second modified example. However, the pedal device 10 of the fourth modified example does not include the reference pin 91, and the mounting hole 90A is not formed in the bracket 90. Instead, the bracket 90 of the fourth modified example is formed with a substantially rectangular reference protrusion (reference shaft member) 90B by cutting and raising. Fig.17 As shown, the extension line EL passing through the interior of the reference protrusion 90B and extending in the extension direction (cutting direction) of the reference protrusion 90B is parallel to the extension line EL of the reference pin 91. Moreover, the width wt of the reference protrusion 90B is the same as the outer diameter D3 of the portion of the reference pin 60 located above the anti-separation claw 60B1 in the above embodiment.

[0100] like Fig.18 As shown in FIG. 1 , when the reference protrusion 90B is inserted into the reference hole 59D formed on the lower surface of the housing portion 59, a first gap CL1 (at Fig.18 When the reference protrusion 90B is inserted into the reference hole 59D, the lower surface of the housing 59 contacts the upper surface of the bracket 90, and the extension line EL of the reference protrusion 90B contacts the stepping reference position 68X of the pedal pad 68 (at Fig.17 , 18 (illustration omitted) cross.

[0101] Therefore, also in the fourth modification, the base member 52 can be fixed to the support member 36 (the floor 30 , the bracket 90 ) so as to prevent the relative position of the stepping reference portion 68X with respect to the support member 36 from being greatly deviated from the designed position.

[0102] <Fifth Modification>

[0103] Fig.19 and Fig. 20 The basic structure of the pedal device 10 of the fifth modification example is the same as that of the second modification example. However, the pedal device 10 of the fifth modification example does not have the reference hole 59D and the reference pin 91. Instead, the pedal device 10 of the fifth modification example has a reference bolt (reference shaft member) 93 and a receiving member 94.

[0104] The metal reference bolt (reference shaft member) 93 has a cylindrical threaded portion 93A and a disc-shaped head portion 93B having a larger diameter than the threaded portion 93A.

[0105] A cylindrical containing member 94 with an open lower surface is fixed to the lower surface of the housing portion 59. The lower surface of the containing member 94 is exposed at the lower surface of the housing portion 59. For example, by insert molding in a state where the containing member 94 is arranged inside a forming mold (not shown in the figure), a member in which the base member 52 and the containing member 94 are integrated is obtained. The containing member 94 is made of resin. The inner diameter of the cylindrical reference hole 94A formed on the bottom surface of the containing member 94 is larger than the outer diameter of the threaded portion 93A. In addition, a female thread groove (not shown in the figure) is formed on the inner circumferential surface of the reference hole 94A.

[0106] The threaded portion 93A of the reference bolt 93 is inserted into the mounting hole 90A from the lower side of the bracket 90, and the head 93B is fixed to the bracket 90. The upper portion of the threaded portion 93A protrudes upward from the bracket 90. The upper portion of the threaded portion 93A is inserted into the reference hole 94A while rotating relative to the lower surface of the housing portion 59 until the lower surface of the housing portion 59 contacts the upper surface of the bracket 90. As a result, the male thread portion of the threaded portion 93A is screwed into the female thread groove of the reference hole 94A, and a first gap CL1 (not shown in the figure) is formed between the threaded portion 93A and the reference hole 94A. Furthermore, the extension line EL of the threaded portion 93A is aligned with the stepping-in reference portion 68X of the pedal pad 68 (at Fig.19 and Fig. 20 (illustration omitted) cross.

[0107] In the fifth modification, the base member 52 (housing portion 59) can rotate relative to the bracket 90 (reference bolt 93) about the extension line EL. Therefore, in the fifth modification, the base member 52 can be fixed to the support member 36 (floor 30, bracket 90) in a manner that avoids the relative position of the stepping reference portion 68X relative to the support member 36 from deviating significantly from the designed position.

[0108] <Sixth Modification>

[0109] Fig.21The pedal device 10 of the sixth modified example shown in the figure is provided with a rivet 95 as a reference shaft member instead of the reference pin 60, the reference protrusion 90B, the reference pin 91, and the reference bolt 93. In addition, a through hole 58C is formed in the fixed portion 58. The rivet 95 is inserted into the through hole 58C and the reference holes 34A and 30A2 which are coaxial with each other. The rivet 95 has a head 95A as its upper end and a cylindrical shaft portion 95B with a smaller diameter than the head 95A. The head 95A faces the upper surface of the fixed portion 58, and the shaft portion 95B penetrates the through hole 58C and the reference holes 34A and 30A2 from the upper side to the lower side. The lower end of the shaft portion 95B becomes a rivet portion 95C with a larger diameter than the reference hole 30A2 by plastic deformation. A first gap CL1 (not shown) is formed between the inner peripheral surface of the reference holes 34A and 30A2 and the shaft portion 95B. The extension line EL of the shaft portion 95B and the stepping reference position 68X of the pedal pad 68 (at Fig.21 (illustration omitted) cross.

[0110] In the sixth modification, the base member 52 (housing portion 59) can rotate relative to the support member 36 about the extension line EL. Therefore, in the sixth modification, the base member 52 can be fixed to the support member 36 in a manner that prevents the relative position of the stepping reference portion 68X relative to the support member 36 from deviating significantly from the designed position.

[0111] As the fixing shaft member, a rivet may be used instead of the fixing bolts 78 and 80. In this case, the weld nuts 38 and 40 are omitted from the bracket 34. Then, the other end of the rivet, i.e., the caulking portion, is pressed against the lower surface of the bracket 34 while the head provided at one end of the rivet is pressed against the bottom surface of the protrusion 58A (58B).

[0112] In the above-described embodiment and each modified example, the number of fixing through holes and fixing shaft members (fixing bolts, rivets) formed in the base member 52 may be one or three or more.

[0113] When a plurality of fixing through holes are provided, only a part of the fixing through holes may be formed as long holes.

[0114] In the above-described embodiment, the case portion 59 and the reference pin 60 may be manufactured separately, and the reference pin 60 may be fixed to the case portion 59 after both are manufactured.

[0115] In the second modification, the reference pin 91 may be provided on the base member 52 , and the reference hole may be provided on the bracket 90 .

[0116] In the third modified example, the reference pin 91 may be provided on the base member 52 , and the reference hole may be provided on the floor panel 30 .

[0117] In the fourth modification, the bracket 90 may be omitted and the reference protrusion 90B may be provided on the floor panel 30 .

[0118] In the fourth modification, the reference protrusion 90B may be provided on the base member 52 , and the reference hole may be provided on the bracket 90 .

[0119] In the fourth modification, the reference protrusion 90B may be provided on the base member 52 , and the reference hole may be provided in the floor panel 30 .

[0120] In the fifth modification, the bracket 90 may be provided with the storage member 94 , and the bolts fixed to the base member 52 may be inserted into the reference holes 94A of the storage member 94 .

[0121] In the fifth modification, the floor panel 30 may be provided with the storage member 94 , and the bolts fixed to the base member 52 may be inserted into the reference holes 94A of the storage member 94 .

[0122] In the above-mentioned embodiment and each modification, the reference hole into which the reference pin is inserted may be a bottomed hole. However, in this case, the reference pin does not include the anti-separation claw 60B1.

[0123] In the above-described embodiment and each modified example, the extension line EL may intersect with a portion of the pedal pad 68 located at the initial position that is different from the depression reference portion 68X.

[0124] The portion corresponding to the dash panel 16 and the portion corresponding to the floor panel 30 may be formed by a panel (not shown) which is an integrally molded product.

[0125] The driving source of the vehicle may be an electric motor instead of an engine. In addition, the vehicle may include an engine and an electric motor as driving sources.
