[0007] Patent Document 1: U.S. Patent No. 9079570 Summary of the invention

[0008] According to the inventor's research, in the pedal device described in Patent Document 1, the spring housing is installed outside the pedal housing, and a part of the spring is exposed outside the spring housing. Therefore, the spring is exposed outside the pedal device. As a result, foreign matter such as dust and moisture can easily enter the spring from the outside of the pedal device. Therefore, the deformation of the spring is easily hindered.

[0009] An object of the present disclosure is to provide a pedal device that suppresses the intrusion of foreign matter into an elastic member.

[0010] According to one viewpoint of the present disclosure, a pedal device comprises: a pedal, which is rotated around a rotation axis (O) as a center by an operator stepping on it; an elastic component, which is deformed by the force from the pedal when the pedal rotates, thereby generating a reaction force against the operator's stepping force; a shell, which supports the pedal in a manner that the pedal can rotate and forms a shell space that serves as a space for accommodating the elastic component; and a supporting component, which supports the elastic component; the shell has an opening portion that forms an open space, and the open space is a space that is demarcated by opening in one direction, the open space is connected to the shell space, and the shell is connected to the supporting component, so that the supporting component blocks the open space, whereby the elastic component is surrounded by the shell and the supporting component.

[0011] Thus, the elastic member is prevented from being exposed to the outside of the pedal device, and the housing and the support member prevent foreign matter from entering the elastic member from the outside of the pedal device. Therefore, the entry of foreign matter into the elastic member is prevented.

[0012] In addition, the reference numerals in parentheses attached to each component etc. represent an example of the correspondence relationship between the component etc. and the specific components etc. described in the embodiment described later. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Hereinafter, the embodiments will be described with reference to the drawings. In the following embodiments, the same or equivalent parts are denoted by the same reference numerals, and their description is omitted.

[0045] (First embodiment)

[0046] The pedal device 1 of this embodiment is used, for example, Figure 1 The brake pedal is used as a brake pedal in a brake-by-wire system 150 for controlling the braking of the vehicle 6. First, the brake-by-wire system 150 will be described.

[0047] like Figure 2 As shown, the brake-by-wire system 150 includes wheel cylinders 131 to 134 , an ECU 110 , a brake circuit 120 , and a pedal device 1 .

[0048] The wheel cylinders 131 to 134 are respectively disposed on the wheels of the vehicle 6. In addition, a brake pad (not shown) is attached to each of the wheel cylinders 131 to 134.

[0049] ECU110 includes a first ECU111 and a second ECU112. The first ECU111 includes a microcomputer and a drive circuit, etc., which are not shown in the figure. In addition, the first ECU111 controls a first brake circuit 121 of a brake circuit 120, which is described later, based on a signal from a pedal device 1, which is described later. The second ECU112 includes a microcomputer and a drive circuit, etc., which are not shown in the figure. Furthermore, the second ECU112 controls a second brake circuit 122 of a brake circuit 120, which is described later, based on a signal from a pedal device 1, which is described later.

[0050] The brake circuit 120 includes a first brake circuit 121 and a second brake circuit 122. The first brake circuit 121 includes a reservoir 124, a motor 123, a gear mechanism 125, and a master cylinder 126. The reservoir 124 stores brake fluid. The motor 123 drives the gear mechanism 125. The gear mechanism 125 causes the master piston 127 of the master cylinder 126 to reciprocate in the axial direction of the master cylinder 126. The second brake circuit 122 includes an electromagnetic valve, which is not shown in the figure, etc. In addition, the second brake circuit 122 opens and closes the electromagnetic valve according to the control signal from the second ECU 112, thereby controlling the hydraulic pressure of each wheel cylinder 131 to 134.

[0051] Here, in order to explain the following pedal device 1, Figure 1As shown in the figure, the front-to-back direction of the vehicle 6 is the vehicle front-to-back direction Da. The top-to-bottom direction of the vehicle 6 is the vehicle up-down direction Db. The left-to-right direction of the vehicle 6 is the vehicle left-to-right direction Dc. The front in the vehicle front-to-back direction Da is referred to as the vehicle front. The rear in the vehicle front-to-back direction Da is referred to as the vehicle rear. The top in the vehicle up-to-down direction Db is referred to as the vehicle top. The bottom in the vehicle up-to-down direction Db is referred to as the vehicle bottom. The left in the vehicle left-to-right direction Dc is referred to as the vehicle left. The right in the vehicle left-to-right direction Dc is referred to as the vehicle right.

[0052] like Figure 2 to Figure 9 As shown, the pedal device 1 includes a pedal 10 , a stroke sensor 30 , a housing 40 , a reaction force generating mechanism 60 , and a supporting member 80 .

[0053] The pedal 10 is operated by being stepped on by the driver of the vehicle 6. Specifically, the pedal 10 includes a pedal portion 12, a lever portion 14, a lever protrusion 16, and a lever flange portion 18.

[0054] like Figure 3 , Figure 4 and Fig. 9 As shown in FIG. 1 , the pedal portion 12 is stepped on by the driver. The rod portion 14 is connected to the pedal portion 12. Figure 3 to Figure 5 and Fig. 9 As shown in FIG. 1 , when the pedal portion 12 is stepped on by the driver, the rod portion 14 rotates around the rotation axis O. Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the lever protrusion 16 is connected to the vehicle front side of the lever portion 14 and protrudes toward the vehicle front from the boundary with the lever portion 14. The lever flange portion 18 is connected to the lever protrusion 16 and protrudes from the boundary with the lever protrusion 16 in a direction orthogonal to the protruding direction of the lever protrusion 16.

[0055] like Figure 2 to Figure 4 and Fig. 9 As shown, the stroke sensor 30 is, for example, arranged on the rotation axis O of the rod portion 14. In addition, the stroke sensor 30 has a magnet, a yoke, a Hall element, etc. Thus, the stroke sensor 30 detects the rotation angle and the stroke amount of the pedal 10 by detecting the rotation angle of the rod portion 14. Furthermore, the stroke sensor 30 outputs signals corresponding to the detected rotation angle and the stroke amount of the pedal 10 to the first ECU 111 and the second ECU 112. In addition, the stroke sensor 30 has a Hall element to measure the rotation angle and the stroke amount of the pedal 10, but is not limited to this, and the rotation angle and the stroke amount of the pedal 10 can also be detected by having an MR element, etc. MR is the abbreviation of Magneto Resistive. In addition, the stroke amount is, for example, the movement amount of the pedal portion 12 in the front-rear direction Da of the vehicle.

[0056] The housing 40 supports the pedal 10 in a manner that allows the pedal 10 to rotate. In addition, the housing 40 is formed into a bottomed cylindrical shape, thereby accommodating a portion of the rod 14, the stroke sensor 30, and a reaction force generating mechanism 60 described later. Specifically, Figure 2 to Figure 7 and Fig. 9 As shown, the housing 40 has a rod support portion 402, a rear wall 404, a left side wall 406, a right side wall 408, a lower wall 410, a housing space 412, a pedal opening portion 414, and a pedal opening space 416. In addition, the housing 40 has a mechanism opening portion 418, a mechanism opening space 420, a first housing extension portion 422, a first housing claw portion 424, a second housing extension portion 426, and a second housing claw portion 428.

[0057] like Figure 4 and Fig. 9 As shown, the rod support portion 402 extends in the vehicle front-rear direction Da and the vehicle left-right direction Dc. In addition, the rotation axis O of the rod portion 14 and the stroke sensor 30 are mounted on the rod support portion 402. Furthermore, the rod support portion 402 supports a part of the rod portion 14 so that the rod portion 14 can rotate around the rotation axis O as the center, and supports the stroke sensor 30.

[0058] like Figure 4 , Figure 5 and Fig. 9 As shown, the rear wall 404 is a wall on the vehicle rear side of the housing 40. In addition, the rear wall 404 is connected to a portion of the rod support 402 on the vehicle rear side.

[0059] like Figure 5 As shown, the left side wall 406 is a wall on the vehicle left side of the housing 40. In addition, the left side wall 406 is connected to a portion on the vehicle left side of the rod support 402. Furthermore, the left side wall 406 is connected to a portion on the vehicle left side of the rear wall 404.

[0060] The right side wall 408 is a wall on the vehicle right side of the housing 40. The right side wall 408 is connected to a portion on the vehicle right side of the rod support 402. Furthermore, the right side wall 408 is connected to a portion on the vehicle right side of the rear wall 404.

[0061] like Figure 4 and Fig. 9 As shown, the lower wall 410 is a wall on the vehicle lower side in the housing 40. The lower wall 410 is connected to a portion on the vehicle lower side in the left side wall 406. Furthermore, the lower wall 410 is connected to a portion on the vehicle lower side in the right side wall 408.

[0062] like Figure 4 , Figure 5 and Fig. 9As shown, the housing space 412 is a space defined by the rod support portion 402 , the rear wall 404 , the left side wall 406 , the right side wall 408 , and the lower wall 410 .

[0063] like Figure 4 and Fig. 9 As shown, the pedal opening 414 is composed of an end portion on the lower side of the vehicle in the rear wall 404 , an end portion on the lower side of the vehicle in the left side wall 406 , an end portion on the lower side of the vehicle in the right side wall 408 , and an end portion on the rear side of the vehicle in the lower wall 410 .

[0064] The pedal opening space 416 is formed by the pedal opening portion 414. The pedal opening space 416 communicates with the housing space 412 in the vehicle vertical direction Db and communicates with the external space of the housing 40 in the vehicle vertical direction Db. Furthermore, a part of the rod 14 is inserted into the pedal opening space 416.

[0065] like Figure 4 , Figure 5 and Fig. 9 As shown, the mechanism opening 418 is formed by the end of the rod support 402 on the vehicle front side, the end of the left side wall 406 on the vehicle front side, the end of the right side wall 408 on the vehicle front side, and the end of the lower wall 410 on the vehicle front side. Therefore, the mechanism opening 418 opens toward the vehicle front.

[0066] The mechanism opening space 420 is formed by the mechanism opening portion 418. The mechanism opening space 420 communicates with the housing space 412 in the vehicle front-rear direction Da. The mechanism opening space 420 is a space for accommodating the reaction force generating mechanism 60 described later in the housing space 412.

[0067] The first housing extension portion 422 , the first housing claw portion 424 , the second housing extension portion 426 , and the second housing claw portion 428 form a snap fit.

[0068] Specifically, if Figure 4 , Figure 6 and Fig. 9 As shown, the first housing extension 422 is connected to the end of the mechanism opening 418 on the vehicle front side and the vehicle upper side, and is connected to the end of the rod support 402 on the vehicle front side. In addition, the first housing extension 422 extends from the end of the rod support 402 on the vehicle front side toward the front of the vehicle.

[0069] The first housing claw portion 424 is connected to the first housing extension portion 422 on the opposite side to the rod support portion 402. The first housing claw portion 424 extends from the first housing extension portion 422 in a direction intersecting the direction in which the first housing extension portion 422 extends. For example, the first housing claw portion 424 extends from the first housing extension portion 422 toward the upper side of the vehicle.

[0070] like Figure 4 , Figure 7 and Fig. 9 As shown, the second housing extension 426 is connected to the end of the mechanism opening 418 on the vehicle front side and the vehicle bottom side, and here is connected to the end of the lower wall 410 on the vehicle front side. In addition, the second housing extension 426 extends from the end of the lower wall 410 on the vehicle front side toward the front of the vehicle.

[0071] The second housing claw portion 428 is connected to the second housing extension portion 426 on the side opposite to the lower wall 410. The second housing claw portion 428 extends from the second housing extension portion 426 in a direction intersecting the direction in which the second housing extension portion 426 extends. For example, the second housing claw portion 428 extends from the second housing extension portion 426 toward the lower side of the vehicle.

[0072] like Figure 4 and Figure 5 As shown in FIG. 1 , the reaction force generating mechanism 60 generates a reaction force to the pedal force applied by the driver to the pedal portion 12. Specifically, Figure 8 As shown, the reaction force generating mechanism 60 includes a first holder 61 , a second holder 62 , a guide member 63 , a first elastic member 71 , a second elastic member 72 , and a third elastic member 73 .

[0073] The first holder 61 is formed of, for example, resin. The first holder 61 includes a first support portion 610, a holder protrusion 612, and a first guide portion 614. The first holder 61 is formed of resin, but is not limited thereto, and may be formed of, for example, metal.

[0074] The first support portion 610 is formed, for example, in a plate shape extending in a direction perpendicular to the vehicle front-rear direction Da. The retainer protrusion 612 is connected to the first support portion 610 and protrudes from the first support portion 610 toward the rear of the vehicle. The first guide portion 614 is formed, for example, in a cylindrical shape extending from the side of the first support portion 610 opposite to the retainer protrusion 612 toward the front of the vehicle.

[0075] The second holder 62 is formed of, for example, resin. In addition, the second holder 62 includes a second support portion 620, a second guide portion 622, a third guide portion 623, and a third support portion 626. In addition, the second holder 62 is formed of resin, but is not limited thereto, and may be formed of, for example, metal or the like.

[0076] The second support portion 620 is formed in a plate shape extending in a direction perpendicular to the vehicle front-rear direction Da, and is formed in an annular shape.

[0077] The second guide portion 622 is connected to the outer side of the second support portion 620 in a direction orthogonal to the vehicle front-rear direction Da, and is formed into a cylindrical shape extending from the boundary portion with the second support portion 620 toward the rear of the vehicle. In addition, a part of the first guide portion 614 is inserted into the hole of the second guide portion 622. As a result, the movement of the first guide portion 614 and the second guide portion 622 in the vehicle up-down direction Db is mutually restricted. Furthermore, since the first guide portion 614 and the second guide portion 622 extend in the vehicle front-rear direction Da, the outer surface of the first guide portion 614 and the inner surface of the second guide portion 622 slide along the vehicle front-rear direction Da.

[0078] The third guide portion 623 is connected to the inner side of the second support portion 620 in a direction perpendicular to the vehicle front-rear direction Da, and is formed in a bottomed cylindrical shape extending from a boundary portion with the second support portion 620 toward the vehicle rear.

[0079] The third support portion 626 is formed in a plate shape extending in a direction perpendicular to the vehicle front-rear direction Da, and is formed in an annular shape. In addition, the third support portion 626 is connected to the side of the second guide portion 622 opposite to the second support portion 620, and is arranged on the vehicle rear side compared to the second support portion 620. Furthermore, a part of the first guide portion 614 is inserted into the hole of the third support portion 626.

[0080] The guide member 63 is formed of metal, for example. In addition, the guide member 63 is formed into a cylindrical shape extending in the vehicle front-rear direction Da. Furthermore, a portion of the guide member 63 is inserted into the hole of the second support portion 620 and the hole of the third guide portion 623. As a result, the movement of the third guide portion 623 and the guide member 63 in the vehicle up-down direction Db is mutually restricted. In addition, since the third guide portion 623 and the guide member 63 extend in the vehicle front-rear direction Da, the inner surface of the third guide portion 623 and the outer surface of the guide member 63 slide along the vehicle front-rear direction Da.

[0081] The first elastic member 71, the second elastic member 72 and the third elastic member 73 are arranged in series here. Specifically, the first elastic member 71 is, for example, a coil spring, and is elastically deformed in the vehicle front-rear direction Da. In addition, the third guide portion 623 is arranged inside the first elastic member 71. As a result, the movement of the first elastic member 71 in the vehicle up-down direction Db is restricted. Furthermore, the first elastic member 71 is supported by the first supporting portion 610 and the second supporting portion 620 by contacting with the first supporting portion 610 and the second supporting portion 620. In addition, when the pedal portion 12 is not stepped on by the driver, the first elastic member 71 is elastically deformed, and is compressed here. In addition, when the pedal portion 12 is not stepped on by the driver, the first elastic member 71 is elastically deformed, but it is not limited to this, and it may not be elastically deformed. In this case, the length of the first elastic member 71 is a free length.

[0082] The second elastic member 72 is, for example, a coil spring, and is elastically deformed in the vehicle front-rear direction Da. In addition, the second elastic member 72 is supported by the second supporting portion 620 and the supporting member 80 described later by contacting the third supporting portion 626 and the supporting member 80 described later. Furthermore, the second supporting portion 620, the second guide portion 622 and the supporting member 80 described later are arranged inside the second elastic member 72. Thus, the movement of the second elastic member 72 in the vehicle up-down direction Db is restricted. In addition, when the second elastic member 72 is projected toward the first elastic member 71 in the vehicle up-down direction Db, the projected second elastic member 72 overlaps with the first elastic member 71. In addition, when the pedal portion 12 is not stepped on by the driver, the second elastic member 72 is elastically deformed, and is compressed here. In addition, here, when the pedal portion 12 is not stepped on by the driver, the second elastic member 72 is elastically deformed, but it is not limited to this, and it may not be elastically deformed. In this case, the length of the second elastic member 72 is a free length.

[0083] The third elastic member 73 is, for example, a coil spring, and is elastically deformed in the vehicle front-rear direction Da. In addition, the third elastic member 73 is supported by the first support portion 610 by contacting the first support portion 610. Furthermore, a retainer convex portion 612 is disposed inside the third elastic member 73. Thus, the movement of the third elastic member 73 in the vehicle up-down direction Db is restricted. In addition, when the pedal portion 12 is not stepped on by the driver, the third elastic member 73 contacts the rod flange portion 18 by inserting a part of the rod convex portion 16 inside the third elastic member 73. At this time, the third elastic member 73 is elastically deformed, and is compressed here. In addition, here, when the pedal portion 12 is not stepped on by the driver, the third elastic member 73 is elastically deformed, but it is not limited to this, and it may not be elastically deformed. In this case, the length of the third elastic member 73 is a free length. In addition, when the pedal portion 12 is not stepped on by the driver, the third elastic member 73 contacts the rod flange portion 18, but it is not limited to this. When the pedal portion 12 is not stepped on by the driver, the third elastic member 73 may be separated from the lever flange portion 18 so that the third elastic member 73 and the lever flange portion 18 are not in contact with each other.

[0084] The support member 80 supports the reaction force generating mechanism 60. Figure 1 As shown, the support member 80 is mounted on a dash panel 200 of the vehicle 6. The dash panel 200 is a partition wall that separates the vehicle exterior 7 and the vehicle interior 8 of the engine room of the vehicle 6, and is sometimes referred to as a partition. In addition, not only the engine of the vehicle 6 but also, for example, a battery, an air conditioner, etc. of the vehicle 6 are arranged outside the vehicle exterior 7.

[0085] Specifically, if Figures 4 to 9 As shown, the support member 80 has a support portion 800 , a panel hole 802 , a panel bolt 804 , an elastic member restricting portion 806 , a first guide member hole 811 , a second guide member hole 812 , a first member hole 821 , and a second member hole 822 .

[0086] The support portion 800 is formed of metal, for example, in a plate shape extending in the vehicle vertical direction Db and the vehicle horizontal direction Dc. In addition, the support portion 800 supports the portion of the second elastic member 72 opposite to the third support portion 626. In addition, the support portion 800 is formed of metal, but is not limited to this. For example, the support portion 800 may also be formed of resin.

[0087] like Figure 4 As shown, a panel hole 802 is formed in the support portion 800. In addition, a panel bolt 804 is inserted into the panel hole 802 and the hole of the dash panel 200. Thus, the support member 80 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0088] The elastic member restriction portion 806 is connected to the support portion 800 and protrudes from the boundary portion with the support portion 800 toward the rear of the vehicle. Figure 8 As shown in FIG. 8 , the elastic member restriction portion 806 is disposed inside the second elastic member 72. Therefore, the movement of the second elastic member 72 in the vehicle up-down direction Db is restricted.

[0089] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the first hole 811 for the guide member is formed in the support portion 800. The second hole 812 for the guide member is formed in the elastic member restriction portion 806 and communicates with the first hole 811 for the guide member. In addition, a part of the guide member 63 is inserted into the first hole 811 for the guide member and the second hole 812 for the guide member. Thus, the support member 80 and the guide member 63 are fixed.

[0090] like Figure 4 , Figure 6 and Fig. 9 As shown, the first component hole 821 is formed in the upper side of the vehicle in the support portion 800. In addition, the first component hole 821 is a through hole extending in the front-rear direction Da of the vehicle. In addition, the first component hole 821 is not limited to a through hole. The first component hole 821 may be, for example, a bottomed hole. In this case, the first component hole 821 is formed, for example, by a 3D printer or the like.

[0091] Here, if Fig. 9 As shown in FIG. 1 , when the first shell claw portion 424 is inserted into the first component hole 821, the first shell extension portion 422 is elastically deformed. Furthermore, if the support member 80 is brought close to the shell 40, as shown in FIG. Figure 4 As shown in FIG. 1 , the shape of the first housing extension 422 returns to its original shape, and the first housing extension 422 is inserted into the first component hole 821. At this time, the first housing claw 424 contacts the support portion 800. As a result, the support portion 800 is connected to the mechanism opening 418, and the support component 80 is engaged with the housing 40. In addition, a recessed portion corresponding to the shape of the first housing claw 424 is formed in the dash panel 200 so that the first housing claw 424 does not contact the dash panel 200.

[0092] like Figure 4 , Figure 7 and Fig. 9As shown, the second component hole 822 is formed in the portion of the support portion 800 on the lower side of the vehicle. In addition, the second component hole 822 is a through hole extending in the vehicle front-rear direction Da. In addition, the second component hole 822 is not limited to a through hole. The second component hole 822 may be, for example, a bottomed hole. In this case, the second component hole 822 is formed, for example, by a 3D printer or the like.

[0093] In addition, here Fig. 9 As shown in FIG. 1 , when the second shell claw 428 is inserted into the second member hole 822, the second shell extension 426 is elastically deformed. Figure 4 As shown in FIG. 1 , the shape of the second housing extension 426 returns to its original shape, and the second housing extension 426 is inserted into the second component hole 822. At this time, the second housing claw 428 contacts the support portion 800. As a result, the support portion 800 is connected to the mechanism opening 418, and the support component 80 is engaged with the housing 40. In addition, a recessed portion corresponding to the shape of the second housing claw 428 is formed in the dash panel 200 so that the second housing claw 428 does not contact the dash panel 200.

[0094] Furthermore, since the support portion 800 is connected to the mechanism opening portion 418, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40.

[0095] As described above, the brake-by-wire system 150 is constructed. Figure 4 and Figure 8 The operation of the pedal device 1 will be described.

[0096] When the pedal portion 12 is stepped on by the driver of the vehicle 6, the rod portion 14 rotates together with the pedal portion 12 about the rotation axis O. As a result, the force from the pedal portion 12 is transmitted to the third elastic member 73 via the rod flange portion 18, so the third elastic member 73 is compressed. In addition, the force from the pedal portion 12 is transmitted to the first retainer 61. Therefore, the first retainer 61 moves toward the front of the vehicle, so the outer surface of the first guide portion 614 and the inner surface of the second guide portion 622 slide along the front of the vehicle, and the first elastic member 71 is compressed by being pushed by the first support portion 610. Furthermore, the force from the pedal portion 12 is transmitted to the second retainer 62. As a result, the second retainer 62 moves toward the front of the vehicle, so the inner surface of the third guide portion 623 and the outer surface of the guide member 63 slide along the front of the vehicle, and the second elastic member 72 is compressed by being pushed by the third support portion 626. Therefore, a reaction force is generated by the restoring force generated by the compression of the first elastic member 71, the second elastic member 72, and the third elastic member 73. By this reaction force, the pedal device 1 can obtain the same reaction force as when the master cylinder 126 is connected, that is, when the reaction force is obtained based on the oil pressure, even if the mechanical connection between the pedal 10 and the master cylinder 126 is abolished.

[0097] At this time, the stroke sensor 30 detects the rotation angle and stroke of the pedal portion 12 by detecting the rotation angle of the rod portion 14. The stroke sensor 30 outputs the detected rotation angle and stroke of the pedal portion 12 to the first ECU 111 and the second ECU 112.

[0098] At this time, the first ECU 111 rotates the motor 123 by, for example, supplying power to the motor 123. As a result, the gear mechanism 125 is driven, so that the primary piston 127 moves. Therefore, the hydraulic pressure of the brake fluid supplied from the reservoir 124 to the master cylinder 126 increases. The increased hydraulic pressure is supplied to the second brake circuit 122.

[0099] In addition, the second ECU 112 supplies power to the solenoid valve (not shown) of the second brake circuit 122, for example. As a result, the solenoid valve of the second brake circuit 122 opens. Therefore, the brake fluid supplied to the second brake circuit 122 is supplied to each wheel cylinder 131 to 134. Therefore, the brake pads installed on the wheel cylinders 131 to 134 rub against the brake discs corresponding to them. As a result, each wheel is braked, so the vehicle 6 slows down. In addition, at this time, the second ECU 112 can also perform ABS control, VSC control, collision avoidance control, regeneration coordination control, etc. based on the signal from the stroke sensor 30 and the signal from other electronic control devices (not shown). In addition, ABS is the abbreviation of Anti-lock Braking System. Furthermore, VSC is the abbreviation of Vehicle Stability Control.

[0100] Next, when the driver of the vehicle 6 stops stepping on the pedal portion 12, the first retainer 61 and the second retainer 62 are pushed back toward the rear of the vehicle by the restoring force of the first elastic member 71 and the second elastic member 72. As a result, the outer surface of the first guide portion 614 and the inner surface of the second guide portion 622 slide along the rear of the vehicle, and the inner surface of the third guide portion 623 and the outer surface of the guide member 63 slide along the rear of the vehicle. In addition, the rod flange portion 18 is pushed back by the restoring force of the third elastic member 73. Thus, the position of the pedal 10 returns to the initial position when the pedal portion 12 is not stepped on by the driver of the vehicle 6.

[0101] In this way, the pedal device 1 operates. In the pedal device 1, the intrusion of foreign matter into the elastic member is suppressed. Next, the suppression of the intrusion of foreign matter will be described.

[0102] Here, in the devices described in Patent Document 1 and International Publication No. 2019-210945, the pedal is mounted on a pedal housing. In addition, these devices have a spring and a spring housing as an elastic member. The spring generates a reaction force by elastically deforming when the pedal is stepped on. The spring housing supports the spring. Furthermore, the spring housing is mounted on the outside of the pedal housing, and a portion of the spring is exposed outside the spring housing. Therefore, the spring is exposed outside the device. As a result, foreign matter such as dust and moisture can easily invade the spring from outside the device. Therefore, the deformation of the spring is easily hindered.

[0103] In contrast, the pedal device 1 of the present embodiment includes a pedal 10, a second elastic member 72 of a reaction force generating mechanism 60, a housing 40, and a support member 80. The pedal 10 is rotated about the rotation axis O by the driver of the vehicle 6 stepping on it. The second elastic member 72 is deformed by the force from the pedal 10 when the pedal 10 rotates, thereby generating a reaction force to the stepping force of the driver of the vehicle 6. The housing 40 supports the pedal 10 in a manner that the pedal 10 can rotate, and forms a housing space 412. The second elastic member 72 is accommodated in the housing space 412. The support member 80 supports the second elastic member 72. In addition, the driver of the vehicle 6 corresponds to an operator.

[0104] In addition, the housing 40 has a mechanism opening 418. The mechanism opening 418 forms a mechanism opening space 420. The mechanism opening space 420 is a space demarcated by the mechanism opening 418 opening toward the front of the vehicle. In addition, the mechanism opening space 420 is connected to the housing space 412. Furthermore, the housing 40 is connected to the support member 80, and the support member 80 blocks the mechanism opening space 420, so that the second elastic member 72 is surrounded by the housing 40 and the support member 80. In addition, the front of the vehicle corresponds to one direction.

[0105] This prevents the second elastic member 72 from being exposed outside the pedal device 1, and prevents foreign matter from entering the second elastic member 72 from outside the pedal device 1 by the housing 40 and the support member 80. Therefore, entry of foreign matter into the second elastic member 72 is prevented.

[0106] Furthermore, since the reaction force generating mechanism 60 is surrounded by the housing 40 and the support member 80, it becomes difficult for humans to perform haphazard operations on the pedal device 1 or disassemble the pedal device 1. Therefore, such haphazard operations or disassembly are suppressed.

[0107] Furthermore, in the first embodiment, the following effects are also achieved.

[0108] [1-1] The second elastic member 72 is a coil spring. Therefore, the influence of temperature on the elastic coefficient of the second elastic member 72 is relatively small. In addition, the second elastic member 72 has relatively high oil resistance, solvent resistance, and chemical resistance. Therefore, the second elastic member 72 is relatively difficult to deteriorate, so a stable reaction force is generated.

[0109] [1-2] The housing 40 is disposed on the vehicle interior 8 side of the dash panel 200. The dash panel 200 corresponds to a partition wall that divides the vehicle exterior 7 and the vehicle interior 8 of the vehicle 6. The mechanism opening 418 opens in the vehicle front. The vehicle front corresponds to the direction from the housing 40 toward the dash panel 200.

[0110] Thus, it is easy to mount the pedal device 1 on the dash panel 200. Specifically, the support member 80 is disposed between the housing 40 and the dash panel 200, and the housing 40 and the support member 80 are connected in the vehicle front-rear direction Da. Then, the pedal device 1 is mounted on the dash panel 200 while the posture of the pedal device 1 is maintained as it is, without being reversed. Therefore, it is easy to mount the pedal device 1 on the dash panel 200. Therefore, the assembly of the pedal device 1 and the dash panel 200 becomes easy. Thus, the assembly cost of the pedal device 1 is reduced.

[0111] [1-3] The housing 40 includes a first housing extension 422, a first housing claw 424, a second housing extension 426, and a second housing claw 428. The first housing extension 422 and the second housing extension 426 extend from the mechanism opening 418 toward the front of the vehicle. The first housing claw 424 is connected to the first housing extension 422 and extends from the first housing extension 422 toward the upper side of the vehicle. The second housing claw 428 is connected to the second housing extension 426 and extends from the second housing extension 426 toward the lower side of the vehicle. In addition, the first housing extension 422 and the second housing extension 426 correspond to the extensions. The first housing claw 424 and the second housing claw 428 correspond to the claws. The upper side of the vehicle and the lower side of the vehicle correspond to directions intersecting the direction in which the extensions extend.

[0112] In addition, the support member 80 has a first member hole 821 and a second member hole 822. The first housing extension 422 is inserted into the first member hole 821. The second housing extension 426 is inserted into the second member hole 822. Furthermore, the housing 40 is engaged with the support member 80 by the first housing claw 424 and the second housing claw 428 contacting the support member 80. Thus, the housing 40 and the support member 80 are easily held. In addition, the first member hole 821 and the second member hole 822 correspond to the member space.

[0113] [1-4] When the first case claw portion 424 is inserted into the first component hole 821, the first case extension portion 422 is deformed. Also, when the second case claw portion 428 is inserted into the second component hole 822, the second case extension portion 426 is deformed.

[0114] Thus, the first housing extension 422 can be easily inserted into the first component hole 821 in one operation without using a jig or the like. Furthermore, the second housing extension 426 can be easily inserted into the second component hole 822 in one operation without using a jig or the like. Therefore, the housing 40 and the support member 80 can be easily assembled. Furthermore, since there is no need to use a jig or the like, the assembly cost of the pedal device 1 can be reduced.

[0115] Furthermore, since it is not necessary to fix the housing 40 and the support member 80 using bolts or the like, the number of parts of the pedal device 1 is reduced. Furthermore, since the number of parts of the pedal device 1 is reduced, the cost of the pedal device 1 is reduced.

[0116] [1-5] The support member 80 includes a support portion 800 and an elastic member restriction portion 806. The support portion 800 supports the second elastic member 72. The elastic member restriction portion 806 extends from the support portion 800 in the deformation direction of the second elastic member 72. In addition, the elastic member restriction portion 806 restricts the movement of the second elastic member 72 in the vehicle up-down direction Db. In addition, the vehicle up-down direction Db corresponds to a direction orthogonal to the deformation direction of the second elastic member 72.

[0117] Thereby, the second elastic member 72 can easily stand upright with respect to the support portion 800. Therefore, the second elastic member 72 can be easily inserted into the mechanism opening space 420. Therefore, the assembly of the housing 40 and the support member 80 becomes easy.

[0118] [1-6] The support member 80 supports one end of the second elastic member 72. In addition, the pedal device 1 includes a second retainer 62. The second retainer 62 has a third support portion 626 and a second guide portion 622. The third support portion 626 supports the other end of the second elastic member 72. The second guide portion 622 extends from the third support portion 626 in the deformation direction of the second elastic member 72. In addition, the second guide portion 622 restricts the movement of the second elastic member 72 in the vehicle up-down direction Db. In addition, the third support portion 626 corresponds to the member support portion. The second guide portion 622 corresponds to the member restriction portion.

[0119] This makes it easy for the second elastic member 72 to stand upright. Therefore, the second elastic member 72 is easily inserted into the mechanism opening space 420. This makes it easy to assemble the housing 40 and the support member 80.

[0120] (Second embodiment)

[0121] In the second embodiment, Fig.10 As shown, the first housing extension 422, the first housing claw 424, the second housing extension 426 and the second housing claw 428 are different from those in the first embodiment. In addition, the first component hole 821 and the second component hole 822 are different from those in the first embodiment. Other than that, it is the same as the first embodiment.

[0122] The first housing extension 422 is connected to the end of the mechanism opening 418 on the vehicle front side and the vehicle left side, and is connected to the end of the left side wall 406 on the vehicle front side. The first housing extension 422 extends toward the vehicle front from the end of the left side wall 406 on the vehicle front side. Furthermore, the first housing extension 422 is inserted into the first component hole 821 formed at a position corresponding to the first housing extension 422.

[0123] The first housing claw 424 is connected to the side of the first housing extension 422 opposite to the left side wall 406. In addition, the first housing claw 424 extends from the first housing extension 422 to the left of the vehicle. Furthermore, the first housing claw 424 contacts the support portion 800. As a result, the support portion 800 is connected to the mechanism opening 418, and the support member 80 is engaged with the housing 40.

[0124] The second housing extension 426 is connected to the end of the mechanism opening 418 on the vehicle front side and the vehicle right side, and is connected to the end of the right side wall 408 on the vehicle front side. The second housing extension 426 extends toward the vehicle front from the end of the right side wall 408 on the vehicle front side. The second housing extension 426 is inserted into the second component hole 822 formed at a position corresponding to the second housing extension 426.

[0125] The second shell claw portion 428 is connected to the side of the second shell extension portion 426 opposite to the right side wall 408. In addition, the second shell claw portion 428 extends from the second shell extension portion 426 to the right of the vehicle. Furthermore, the second shell claw portion 428 contacts the support portion 800. Therefore, the support portion 800 is connected to the mechanism opening portion 418, and the support member 80 is engaged with the shell 40. Furthermore, since the support portion 800 is connected to the mechanism opening portion 418, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the shell space 412 and the mechanism opening space 420. As a result, the reaction force generating mechanism 60 is accommodated in the shell space 412 and is surrounded by the support member 80 and the shell 40.

[0126] As described above, the pedal device 1 of the second embodiment is configured. In the second embodiment as well, the same effects as those of the first embodiment are achieved.

[0127] (Third embodiment)

[0128] In the third embodiment, Fig.11 and Fig.12 As shown in FIG. 1 , the second housing claw portion 428 and the second member hole 822 are different from those in the first embodiment. Other than that, the second embodiment is the same as the first embodiment.

[0129] The second housing claw 428 is formed in a cylindrical shape having an axis extending in the vehicle left-right direction Dc. In addition, the second housing extension 426 and the second housing claw 428 are inserted into the second component hole 822. Furthermore, the second component hole 822 is formed in a shape and size that allows the housing 40 to rotate around the axis of the second housing claw 428.

[0130] As described above, the pedal device 1 of the third embodiment is configured. In this third embodiment, the same effects as those of the first embodiment are achieved. In addition, in the third embodiment, the following effects are also achieved.

[0131] [2] The second housing claw 428 is connected to the second housing extension 426 and rotates around an axis extending in the vehicle left-right direction Dc. In addition, when the second housing claw 428 rotates, the housing 40 rotates around the axis of the second housing claw 428, so that the first housing claw 424 is inserted into the first component hole 821. In addition, the first housing extension 422 corresponds to the first extension. The first housing claw 424 corresponds to the first claw. The second housing extension 426 corresponds to the second extension. The second housing claw 428 corresponds to the second claw. The vehicle left-right direction Dc corresponds to a direction orthogonal to the one direction.

[0132] Thus, the housing 40 and the support member 80 can be assembled by rotating the housing 40. Therefore, the degree of freedom in assembling the housing 40 and the support member 80 is improved.

[0133] (Fourth embodiment)

[0134] In the fourth embodiment, Fig.13 As shown in the figure, the housing 40 has a front wall 430 instead of the right side wall 408. In addition, the form of the housing space 412, the pedal opening 414, the mechanism opening 418 and the mechanism opening space 420 is different from that of the first embodiment. Furthermore, the form of the first housing extension 422, the first housing claw 424, the second housing extension 426 and the second housing claw 428 is different from that of the first embodiment. In addition, the support member 80 also has a support member extension 830. Furthermore, the form of the first member hole 821 and the second member hole 822 is different from that of the first embodiment. Other than this, it is the same as the first embodiment.

[0135] The front wall 430 is a wall on the vehicle front side in the housing 40. In addition, the front wall 430 is connected to a portion on the vehicle front side in the rod support portion 402, a portion on the vehicle front side in the left side wall 406, and a portion on the vehicle front side in the lower wall 410. In addition, a panel hole 802 is formed in the front wall 430, and the front wall 430 is located on the vehicle front side compared to the support portion 800. Therefore, the panel hole 802 is not formed in the support portion 800. In addition, the panel bolt 804 is inserted into the panel hole 802 of the front wall 430 and the hole of the dash panel 200. Thus, the housing 40 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0136] The housing space 412 is a space defined by the rod support portion 402 , the rear wall 404 , the left side wall 406 , the lower wall 410 , and the front wall 430 .

[0137] The pedal opening 414 is formed by an end portion of the rear wall 404 on the vehicle lower side, an end portion of the left side wall 406 on the vehicle lower side, and an end portion of the lower wall 410 on the vehicle rear side.

[0138] The mechanism opening 418 is formed by the end of the rod support 402 on the vehicle right side, the end of the rear wall 404 on the vehicle right side, the end of the lower wall 410 on the vehicle right side, and the end of the front wall 430 on the vehicle right side. Therefore, the mechanism opening 418 opens toward the vehicle right. In addition, the vehicle right corresponds to one direction.

[0139] The mechanism opening space 420 is formed by the mechanism opening portion 418 , and communicates with the casing space 412 in the vehicle left-right direction Dc.

[0140] The first housing extension 422 is connected to the end of the mechanism opening 418 on the vehicle front side and the vehicle right side, and here is connected to the end of the front wall 430 on the vehicle right side. In addition, the first housing extension 422 extends from the end of the front wall 430 on the vehicle right side toward the vehicle right.

[0141] The first case claw portion 424 is connected to the first case extension portion 422 on the side opposite to the front wall 430. The first case claw portion 424 extends from the first case extension portion 422 toward the front of the vehicle.

[0142] The second housing extension 426 is connected to the end of the mechanism opening 418 on the vehicle rear side and the vehicle right side, and is connected to the end of the rear wall 404 on the vehicle right side. In addition, the second housing extension 426 extends from the end of the rear wall 404 on the vehicle right side toward the vehicle right.

[0143] The second case claw portion 428 is connected to the second case extension portion 426 at the side opposite to the rear wall 404. The second case claw portion 428 extends from the second case extension portion 426 toward the rear of the vehicle.

[0144] The support member extension 830 is connected to the right side of the support member 800. The support member extension 830 is formed of metal in a plate shape extending in the vehicle front-rear direction Da and the vehicle up-down direction Db. The support member extension 830 is formed of metal, but is not limited thereto. For example, the support member extension 830 may be formed of resin.

[0145] The first component hole 821 is formed in the support component extension 830 instead of being formed in the support portion 800. In addition, the first component hole 821 is a hole extending in the vehicle left-right direction Dc. Furthermore, the first housing extension 422 is inserted into the first component hole 821. In addition, the first housing claw 424 contacts the support component extension 830. As a result, the support component extension 830 is connected to the mechanism opening 418, and the support component 80 is engaged with the housing 40.

[0146] The second component hole 822 is formed in the support component extension 830 instead of being formed in the support portion 800. In addition, the second component hole 822 is a hole extending in the vehicle left-right direction Dc. Furthermore, the second housing extension 426 is inserted into the second component hole 822. In addition, the second housing claw 428 contacts the support component extension 830. As a result, the support component extension 830 is connected to the mechanism opening 418, and the support component 80 is engaged with the housing 40.

[0147] Furthermore, since the support member extension 830 is connected to the mechanism opening 418, the support member extension 830 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40.

[0148] As described above, the pedal device 1 of the fourth embodiment is constructed. In this fourth embodiment, the same effect as that of the first embodiment is achieved. In addition, in the fourth embodiment, the housing 40 may also have a right side wall 408 instead of the left side wall 406. In this case, for example, the housing space 412 is a space formed by the rod support 402, the rear wall 404, the right side wall 408, the lower wall 410 and the front wall 430. In addition, the mechanism opening 418 is composed of the end of the vehicle left side in the rod support 402, the end of the vehicle left side in the rear wall 404, the end of the vehicle left side in the lower wall 410 and the end of the vehicle left side in the front wall 430. At this time, the mechanism opening 418 opens toward the left side of the vehicle. The left side of the vehicle corresponds to one direction. Furthermore, the support member extension 830 is connected to the part of the vehicle left side in the support 800. In addition, the first housing extension 422 extends from the end of the vehicle left side in the front wall 430 to the vehicle left. Furthermore, the second case extension portion 426 extends toward the vehicle left from the end portion on the vehicle left side of the rear wall 404. This configuration is also possible.

[0149] (Fifth embodiment)

[0150] In the fifth embodiment, Fig.14 and Fig.15 As shown, the housing 40 has a front wall 430 instead of the lower wall 410. In addition, the housing 40 has a panel hole 802 and a panel bolt 804 instead of the case where the supporting member 80 does not have the panel hole 802 and the panel bolt 804. Furthermore, the form of the housing space 412, the mechanism opening 418, and the mechanism opening space 420 is different from that of the first embodiment. In addition, the form of the first housing extension 422, the first housing claw 424, the second housing extension 426, and the second housing claw 428 is different from that of the first embodiment. Furthermore, the supporting member 80 has a supporting member extension 830. In addition, the form of the first member hole 821 and the second member hole 822 is different from that of the first embodiment. Other than this, it is the same as the first embodiment.

[0151] The front wall 430 is connected to a portion of the rod support 402 on the vehicle front side, a portion of the left side wall 406 on the vehicle front side, and a portion of the right side wall 408 on the vehicle front side. In addition, a panel hole 802 is formed in the front wall 430. The panel bolt 804 is inserted into the panel hole 802 and the hole of the dash panel 200. Thus, the housing 40 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0152] The housing space 412 is a space defined by the rod support portion 402 , the rear wall 404 , the left side wall 406 , the right side wall 408 , and the front wall 430 .

[0153] The pedal opening 414 is formed by an end portion of the rear wall 404 on the lower side of the vehicle, an end portion of the left side wall 406 on the lower side of the vehicle, and an end portion of the right side wall 408 on the lower side of the vehicle.

[0154] The mechanism opening 418 is formed by the end of the left wall 406 on the vehicle lower side, the end of the right wall 408 on the vehicle lower side, and the portion of the front wall 430 on the vehicle lower side. Therefore, the mechanism opening 418 opens toward the vehicle lower side. In addition, the vehicle lower side corresponds to one direction.

[0155] The mechanism opening space 420 is formed by the mechanism opening portion 418 , and communicates with the casing space 412 in the vehicle up-down direction Db.

[0156] The first housing extension 422 is connected to the end of the mechanism opening 418 on the vehicle left side, here connected to the end of the left side wall 406 on the vehicle lower side. In addition, the first housing extension 422 extends from the end of the left side wall 406 on the vehicle lower side toward the vehicle lower side.

[0157] The first case claw portion 424 is connected to the first case extension portion 422 at the side opposite to the left side wall 406. In addition, the first case claw portion 424 extends from the first case extension portion 422 toward the vehicle left.

[0158] The second housing extension 426 is connected to the end of the mechanism opening 418 on the vehicle right side, here connected to the end of the right side wall 408 on the vehicle lower side. In addition, the second housing extension 426 extends from the end of the right side wall 408 on the vehicle lower side toward the vehicle lower side.

[0159] The second case claw portion 428 is connected to the second case extension portion 426 at the side opposite to the right side wall 408. In addition, the second case claw portion 428 extends from the second case extension portion 426 toward the vehicle right.

[0160] The support member extension 830 is connected to a portion on the vehicle lower side of the support portion 800. The support member extension 830 is formed of metal in a plate shape extending in the vehicle front-rear direction Da and the vehicle left-right direction Dc.

[0161] The first component hole 821 is formed in the support component extension 830 instead of being formed in the support portion 800. In addition, the first component hole 821 is a hole extending in the vehicle up-down direction Db. Furthermore, the first housing extension 422 is inserted into the first component hole 821. In addition, the first housing claw 424 contacts the support component extension 830. As a result, the support component extension 830 is connected to the mechanism opening 418, and the support component 80 is engaged with the housing 40.

[0162] The second component hole 822 is formed in the support component extension 830 instead of being formed in the support portion 800.

In addition, the second housing claw 428 contacts the support component extension 830. As a result, the support component extension 830 is connected to the mechanism opening 418, and the support component 80 is engaged with the housing 40.

[0163] Furthermore, since the support member extension 830 is connected to the mechanism opening 418, the support member extension 830 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40.

[0164] As described above, the pedal device 1 of the fifth embodiment is configured. In this fifth embodiment, the same effects as those of the first embodiment are achieved.

[0165] (Sixth embodiment)

[0166] In the sixth embodiment, Fig.16 As shown in the figure, the support member 80 has a first member extension 841, a first member claw 851, a second member extension 842, and a second member claw 852 instead of the first member hole 821 and the second member hole 822. In addition, the housing 40 does not have the first housing extension 422, the first housing claw 424, the second housing extension 426, and the second housing claw 428. Instead, the housing 40 has a first housing hole 431, a second housing hole 432, a third housing hole 433, and a fourth housing hole 434. Other than this, it is the same as the first embodiment.

[0167] The first member extension portion 841 , the first member claw portion 851 , the second member extension portion 842 , and the second member claw portion 852 constitute a snap fit.

[0168] Specifically, the first member extension portion 841 is connected to a portion on the vehicle upper side of the support portion 800. Furthermore, the first member extension portion 841 extends from a portion on the vehicle upper side of the support portion 800 toward the vehicle rear.

[0169] The first member claw portion 851 is connected to the first member extension portion 841 on the opposite side to the support portion 800. The first member claw portion 851 extends from the first member extension portion 841 in a direction intersecting the direction in which the first member extension portion 841 extends. For example, the first member claw portion 851 extends from the first member extension portion 841 toward the upper side of the vehicle.

[0170] The second member extension portion 842 is connected to a portion on the vehicle lower side of the support portion 800. In addition, the second member extension portion 842 extends from a portion on the vehicle lower side of the support portion 800 toward the vehicle rear.

[0171] The second member claw portion 852 is connected to the second member extension portion 842 on the opposite side from the support portion 800. The second member claw portion 852 extends from the second member extension portion 842 in a direction intersecting the direction in which the second member extension portion 842 extends. For example, the second member claw portion 852 extends from the second member extension portion 842 toward the lower side of the vehicle.

[0172] The first housing hole 431 and the second housing hole 432 are formed in the rod support portion 402. In addition, the first housing hole 431 is a hole extending in the vehicle front-rear direction Da. The second housing hole 432 is connected to the first housing hole 431. Furthermore, the second housing hole 432 is a through hole extending in the vehicle up-down direction Db. In addition, the second housing hole 432 is not limited to a through hole. The second housing hole 432 may also be a bottomed hole, for example.

[0173] Here, when the first member claw 851 is inserted into the first housing hole 431, the first member extension 841 is elastically deformed. Furthermore, when the support member 80 is brought close to the housing 40, the shape of the first member extension 841 returns to its original shape, and the first member extension 841 is inserted into the first housing hole 431. At this time, the first member claw 851 is inserted into the second housing hole 432, and the first member claw 851 contacts the rod support 402. Thus, the support portion 800 is connected to the mechanism opening 418, and the support member 80 is engaged with the housing 40.

[0174] The third housing hole 433 and the fourth housing hole 434 are formed in the lower wall 410. In addition, the third housing hole 433 is a hole extending in the vehicle front-rear direction Da. The fourth housing hole 434 is connected to the third housing hole 433. Furthermore, the fourth housing hole 434 is a through hole extending in the vehicle up-down direction Db. In addition, the fourth housing hole 434 is not limited to a through hole. The fourth housing hole 434 may also be a bottomed hole, for example.

[0175] Here, when the second member claw 852 is inserted into the third housing hole 433, the second member extension 842 is elastically deformed. Furthermore, when the support member 80 is brought close to the housing 40, the shape of the second member extension 842 returns to its original shape, and the second member extension 842 is inserted into the third housing hole 433. At this time, the second member claw 852 is inserted into the fourth housing hole 434, and the second member claw 852 contacts the lower wall 410. Thus, the support member 800 is connected to the mechanism opening 418, and the support member 80 is engaged with the housing 40.

[0176] Furthermore, since the support portion 800 is connected to the mechanism opening portion 418, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40.

[0177] As described above, the pedal device 1 of the sixth embodiment is configured. In the sixth embodiment, the same effects as those of the first embodiment are achieved. In addition, in the sixth embodiment, the following effects are also achieved.

[0178] [3-1] The support member 80 includes a support portion 800, a first member extension portion 841, a first member claw portion 851, a second member extension portion 842, and a second member claw portion 852. The support portion 800 supports the second elastic member 72. The first member extension portion 841 extends from the support portion 800 toward the rear of the vehicle. The first member claw portion 851 is connected to the first member extension portion 841 and extends from the first member extension portion 841 toward the upper side of the vehicle. The second member extension portion 842 extends from the support portion 800 toward the rear of the vehicle. The second member claw portion 852 is connected to the second member extension portion 842 and extends from the second member extension portion 842 toward the lower side of the vehicle. In addition, the first member extension portion 841 and the second member extension portion 842 correspond to the extension portion. The first member claw portion 851 and the second member claw portion 852 correspond to the claw portion. The rear of the vehicle corresponds to the opposite direction of the one direction. The upper side of the vehicle and the lower side of the vehicle correspond to directions intersecting the direction in which the extension portion extends.

[0179] In addition, the housing 40 has a first housing hole 431, a second housing hole 432, a third housing hole 433, and a fourth housing hole 434. The first component extension 841 is inserted into the first housing hole 431. The first component claw 851 is inserted into the second housing hole 432. The second component extension 842 is inserted into the third housing hole 433. The second component claw 852 is inserted into the fourth housing hole 434. Furthermore, the housing 40 is engaged with the support member 80 by the first component claw 851 and the second component claw 852 contacting the housing 40. Thus, the housing 40 and the support member 80 are easily held. In addition, the first housing hole 431 and the third housing hole 433 correspond to the first space. The second housing hole 432 and the fourth housing hole 434 correspond to the second space.

[0180] [3-2] When the first member claw portion 851 is inserted into the first housing hole 431 , the first member extension portion 841 is deformed. Also, when the second member claw portion 852 is inserted into the second housing hole 432 , the second member extension portion 842 is deformed.

[0181] Thus, the first member extension 841 can be easily inserted into the first housing hole 431 in one operation. Also, the second member extension 842 can be easily inserted into the third housing hole 433 in one operation. Therefore, the housing 40 and the support member 80 can be easily assembled.

[0182] Furthermore, since it is not necessary to fix the housing 40 and the support member 80 using bolts or the like, the number of parts of the pedal device 1 is reduced. Furthermore, since the number of parts of the pedal device 1 is reduced, the cost of the pedal device 1 is reduced.

[0183] (Seventh Implementation Method)

[0184] In the seventh embodiment, Fig.17 As shown in the figure, the first housing hole 431, the second housing hole 432, the third housing hole 433 and the fourth housing hole 434 are different from those in the sixth embodiment. In addition, the first component extension 841, the first component claw 851, the second component extension 842 and the second component claw 852 are different from those in the sixth embodiment. Other than that, it is the same as the sixth embodiment.

[0185] The first housing hole 431 and the second housing hole 432 are formed in the left side wall 406. In addition, the second housing hole 432 extends in the vehicle left-right direction Dc instead of extending in the vehicle up-down direction Db.

[0186] The third housing hole 433 and the fourth housing hole 434 are formed in the right side wall 408. In addition, the fourth housing hole 434 extends in the vehicle left-right direction Dc instead of extending in the vehicle up-down direction Db.

[0187] The first member extension 841 is connected to the vehicle left side portion of the support portion 800. The first member extension 841 extends from the vehicle left side portion of the support portion 800 toward the vehicle rear. Furthermore, the first member extension 841 is inserted into the first housing hole 431.

[0188] The first member claw 851 extends from the first member extension 841 toward the vehicle left. The first member claw 851 is inserted into the second housing hole 432 and contacts the left side wall 406. Thus, the support portion 800 is connected to the mechanism opening 418, and the support member 80 is engaged with the housing 40.

[0189] The second member extension 842 is connected to the vehicle right side portion of the support portion 800. The second member extension 842 extends from the vehicle right side portion of the support portion 800 toward the vehicle rear. Furthermore, the second member extension 842 is inserted into the third housing hole 433.

[0190] The second member claw 852 extends from the second member extension 842 toward the right side of the vehicle. In addition, the second member claw 852 is inserted into the fourth housing hole 434 and contacts the right side wall 408. Therefore, the support portion 800 is connected to the mechanism opening portion 418, and the support member 80 is engaged with the housing 40. Furthermore, since the support portion 800 is connected to the mechanism opening portion 418, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. As a result, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40.

[0191] As described above, the pedal device 1 of the seventh embodiment is configured. In this seventh embodiment as well, the same effects as those of the sixth embodiment are achieved.

[0192] (Eighth Implementation Method)

[0193] In the eighth embodiment, Fig.18 and Fig.19 As shown in FIG. 1 , the housing 40 does not have the third housing hole 433 and the fourth housing hole 434. In addition, the form of the second member claw portion 852 is different from that of the sixth embodiment. Other than that, it is the same as the sixth embodiment.

[0194] The second member claw 852 is formed in a cylindrical shape having an axis extending in the vehicle left-right direction Dc. In addition, a portion of the second member claw 852 is inserted into a hole (not shown) formed in the left side wall 406 and a hole (not shown) formed in the right side wall 408. Furthermore, the second member claw 852 is supported by the left side wall 406 and the right side wall 408 so as to be rotatable around the axis extending in the vehicle left-right direction Dc.

[0195] As described above, the pedal device 1 of the eighth embodiment is configured. The eighth embodiment also achieves the same effects as the sixth embodiment. In addition, the eighth embodiment also achieves the following effects.

[0196] [4] The second component claw 852 is connected to the second component extension 842 and rotates around an axis extending in the vehicle left-right direction Dc. In addition, when the second component claw 852 rotates, the support component 80 rotates around the axis of the second component claw 852, so that the first component claw 851 is inserted into the first component hole 821. In addition, the first component extension 841 corresponds to the first extension. The first component claw 851 corresponds to the first claw. The second component extension 842 corresponds to the second extension. The second component claw 852 corresponds to the second claw. The vehicle left-right direction Dc corresponds to a direction orthogonal to the one direction.

[0197] Thus, the housing 40 and the support member 80 can be assembled by rotating the support member 80. Therefore, the degree of freedom in assembling the housing 40 and the support member 80 is improved.

[0198] (Ninth Implementation Method)

[0199] In the ninth embodiment, Fig. 20 As shown in the figure, the housing 40 has a front wall 430 instead of the right side wall 408.

In addition, a panel hole 802 is formed in the front wall 430, and the front wall 430 is located on the vehicle front side compared to the support portion 800. Therefore, the panel hole 802 is not formed in the support portion 800. In addition, the panel bolt 804 is inserted into the panel hole 802 of the front wall 430 and the hole of the dash panel 200. Thus, the housing 40 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0201] The housing space 412 is a space defined by the rod support portion 402 , the rear wall 404 , the left side wall 406 , the lower wall 410 , and the front wall 430 .

[0210] The second member extension 842 is connected to the vehicle rear side portion of the support member extension 830. The second member extension 842 extends from the vehicle rear side portion of the support member extension 830 toward the vehicle left. Furthermore, the second member extension 842 is inserted into the third housing hole 433.

[0211] The second component claw 852 extends from the second component extension 842 toward the rear of the vehicle. In addition, the second component claw 852 is inserted into the fourth shell hole 434 and contacts the rear wall 404. Therefore, the support component extension 830 is connected to the mechanism opening 418, and the support component 80 is engaged with the shell 40. Furthermore, since the support component extension 830 is connected to the mechanism opening 418, the support component extension 830 blocks the mechanism opening space 420. In addition, the second elastic component 72 supported by the support portion 800 is inserted into the shell space 412. As a result, the reaction force generating mechanism 60 is accommodated in the shell space 412 and is surrounded by the support component 80 and the shell 40.

[0212] As described above, the pedal device 1 of the ninth embodiment is constructed. In the ninth embodiment, the same effect as that of the sixth embodiment is achieved. In the ninth embodiment, the housing 40 may have a right side wall 408 instead of the left side wall 406. In this case, for example, the housing space 412 is a space formed by the rod support 402, the rear wall 404, the right side wall 408, the lower wall 410, and the front wall 430.

In addition, the support member 80 does not include the first member hole 821 and the second member hole 822. Other aspects are the same as those of the first embodiment.

[0230] In the eleventh embodiment, the support portion 800 and the mechanism opening portion 418 are connected in the vehicle front-rear direction Da by bonding, fusing, etc. Specifically, the support portion 800 and the end portion on the vehicle front side of the rod support portion 402, the end portion on the vehicle front side of the left side wall 406, the end portion on the vehicle front side of the right side wall 408, and the end portion on the vehicle front side of the lower wall 410 are connected in the vehicle front-rear direction Da by bonding, fusing, etc. Therefore, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. As a result, the reaction force generating mechanism 60 is accommodated in the housing space 412 and surrounded by the support member 80 and the housing 40.

[0231] As described above, the pedal device 1 of the eleventh embodiment is configured. In the eleventh embodiment, the same effects as those of the first embodiment are achieved.

[0232] (12th embodiment)

[0233] In the twelfth embodiment, Fig.24 As shown in FIG. 1 , the housing 40 has a front wall 430, a panel hole 802, and a panel bolt 804. The support member 80 does not have a panel hole 802 and a panel bolt 804. Other than this, the configuration is the same as the eleventh embodiment.

[0234] In the twelfth embodiment, the support portion 800 is inserted into the mechanism opening space 420 by pressing or the like. Thus, the support portion 800 and the mechanism opening portion 418 are connected in a direction orthogonal to the vehicle front-rear direction Da. Specifically, the support portion 800 and the end portion on the vehicle front side of the rod support portion 402 and the end portion on the vehicle front side of the lower wall 410 are connected in the vehicle up-down direction Db. In addition, the support portion 800 and the end portion on the vehicle front side of the left side wall 406 and the end portion on the vehicle front side of the right side wall 408 are connected in the vehicle left-right direction Dc. Therefore, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the shell space 412. Thus, the reaction force generating mechanism 60 is accommodated in the shell space 412 and is surrounded by the support portion 80 and the shell 40.

[0235] The front wall 430 is connected to the end of the rod support portion 402 on the vehicle front side. In addition, the front wall 430 extends upward from the end of the rod support portion 402 on the vehicle front side. Furthermore, the front wall 430 is connected to the end of the lower wall 410 on the vehicle front side. In addition, the front wall 430 extends downward from the end of the lower wall 410 on the vehicle front side.

[0236] The panel hole 802 is formed in the front wall 430. The panel bolt 804 is inserted into the panel hole 802 and the hole of the dash panel 200. Thus, the housing 40 is attached to the dash panel 200. Therefore, the pedal device 1 is attached to the dash panel 200.

[0237] As described above, the pedal device 1 of the twelfth embodiment is configured. In the twelfth embodiment, the same effects as those of the eleventh embodiment are achieved.

[0238] (13th embodiment)

[0239] In the 13th embodiment, Fig.25 As shown in FIG. 4 , the housing 40 further includes a first front wall 471, a second front wall 472, and a panel hole 802. In addition, the form of the support member 80 is different from that of the first embodiment. Other than that, the present invention is the same as the first embodiment.

[0240] The first front wall 471 extends upward from the first housing extension 422. In addition, a step corresponding to the shape of the first front wall 471 is formed at the upper side of the vehicle in the support portion 800. Thus, the support portion 800 and the first front wall 471 are in contact in the vehicle front-rear direction Da.

[0241] The second front wall 472 extends from the second housing extension 426 toward the vehicle bottom. Furthermore, a step corresponding to the shape of the second front wall 472 is formed at the vehicle bottom side of the support portion 800. Therefore, the support portion 800 and the second front wall 472 are in contact in the vehicle front-rear direction Da.

[0242] In addition, the panel hole 802 of the housing 40 is formed in the first front wall 471 and the second front wall 472, and is formed at a position corresponding to the panel hole 802 of the support member 80. Therefore, the panel hole 802 of the housing 40 is communicated with the panel hole 802 of the support member 80. Furthermore, the panel bolt 804 is inserted into the panel hole 802 of the housing 40, the panel hole 802 of the support member 80, and the hole of the dash panel 200. Thus, the housing 40 and the support member 80 are fixed, and the support member 80 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0243] As described above, the pedal device 1 of the thirteenth embodiment is configured. In the thirteenth embodiment, the same effects as those of the first embodiment are achieved.

[0244] (14th embodiment)

[0245] In the 14th embodiment, if Fig.26As shown, the housing 40 further has a housing fixing hole 490. In addition, the support member 80 further has a member fixing hole 890. The pedal device 1 further includes a fixing member 90. Furthermore, the support portion 800 and the mechanism opening portion 418 are not bonded or fused. Other than this, it is the same as the eleventh embodiment.

[0246] The housing fixing hole 490 is formed in the mechanism opening 418. Specifically, the housing fixing hole 490 is formed at the vehicle front end of the rod support 402 and at the vehicle front end of the lower wall 410. The housing fixing hole 490 extends in the vehicle front-rear direction Da.

[0247] The component fixing holes 890 are formed at locations on the vehicle upper side and the vehicle lower side of the support portion 800. In addition, the component fixing holes 890 are formed at positions corresponding to the housing fixing holes 490. Therefore, the component fixing holes 890 and the housing fixing holes 490 are communicated.

[0248] The fixing member 90 is a bolt or the like, and is inserted into the housing fixing hole 490 and the member fixing hole 890. Thus, the support portion 800 is connected to the mechanism opening portion 418, and the housing 40 and the support member 80 are fixed. Furthermore, since the support portion 800 is connected to the mechanism opening portion 418, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic member 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40. In addition, the head of the fixing member 90 and a part of the threaded portion of the fixing member 90 are inserted into the member fixing hole 890 so that the fixing member 90 does not contact the front panel 200. In addition, a part of the threaded portion of the fixing member 90 is inserted into the housing fixing hole 490.

[0249] As described above, the pedal device 1 of the fourteenth embodiment is configured. In the fourteenth embodiment, the same effects as those of the eleventh embodiment are achieved. In addition, in the fourteenth embodiment, the following effects are also achieved.

[0250] [5] The housing 40 further includes a housing fixing hole 490. For example, the housing fixing hole 490 is formed in the mechanism opening 418. The support member 80 further includes a member fixing hole 890. The member fixing hole 890 communicates with the housing fixing hole 490. In addition, the pedal device 1 further includes a fixing member 90. The fixing member 90 is inserted into the housing fixing hole 490 and the member fixing hole 890 to fix the housing 40 and the support member 80.

[0251] Thus, the holding force of the housing 40 and the support member 80 becomes greater than when the housing 40 and the support member 80 are held by snap fit, etc. Therefore, the support member 80 is less likely to be detached from the housing 40 than when the housing 40 and the support member 80 are held by snap fit, etc.

[0252] (15th embodiment)

[0253] In the fifteenth embodiment, Fig. 27 As shown in FIG. 1 , the positions of the housing fixing hole 490, the member fixing hole 890, and the fixing member 90 are different from those in the fourteenth embodiment. Other than that, the present invention is the same as the fourteenth embodiment.

[0254] The housing fixing hole 490 is formed at an end portion on the vehicle front side of the left side wall 406 and an end portion on the vehicle front side of the right side wall 408. Furthermore, the housing fixing hole 490 extends in the vehicle front-rear direction Da.

[0255] The component fixing hole 890 is formed at the position on the vehicle left side and the vehicle right side of the support portion 800. In addition, the component fixing hole 890 is formed at a position corresponding to the housing fixing hole 490. Therefore, the component fixing hole 890 communicates with the housing fixing hole 490.

[0256] Therefore, since the housing fixing hole 490 and the component fixing hole 890 are formed on the left side and the right side of the vehicle, the fixing component 90 is located on the left side and the right side of the vehicle. In addition, the fixing component 90 is inserted into the housing fixing hole 490 and the component fixing hole 890. Thus, the support portion 800 is connected to the mechanism opening portion 418, and the housing 40 and the support component 80 are fixed. Furthermore, since the support portion 800 is connected to the mechanism opening portion 418, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic component 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support component 80 and the housing 40.

[0257] As described above, the pedal device 1 of the fifteenth embodiment is configured. In the fifteenth embodiment as well, the same effects as those of the fourteenth embodiment are achieved.

[0258] (16th Implementation Method)

[0259] In the 16th embodiment, Fig.28As shown in the figure, the housing 40 has a front wall 430 instead of the right side wall 408. In addition, the forms of the housing space 412, the pedal opening 414, the mechanism opening 418, and the mechanism opening space 420 are different from those in the 14th embodiment. Furthermore, the support member 80 has a support member extension 830. In addition, the positions of the housing fixing hole 490, the member fixing hole 890, and the fixing member 90 are different from those in the 14th embodiment. Other than that, it is the same as the 14th embodiment.

[0260] The front wall 430 is connected to a portion of the rod support portion 402 on the vehicle front side, a portion of the left side wall 406 on the vehicle front side, and a portion of the lower wall 410 on the vehicle front side. In addition, a panel hole 802 is formed in the front wall 430, and the front wall 430 is located on the vehicle front side compared to the support portion 800. Therefore, the panel hole 802 is not formed in the support portion 800. In addition, the panel bolt 804 is inserted into the panel hole 802 of the front wall 430 and the hole of the dash panel 200. Thus, the housing 40 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0261] The housing space 412 is a space defined by the rod support portion 402 , the rear wall 404 , the left side wall 406 , the lower wall 410 , and the front wall 430 .

[0262] The pedal opening 414 is formed by an end portion of the rear wall 404 on the vehicle lower side, an end portion of the left side wall 406 on the vehicle lower side, and an end portion of the lower wall 410 on the vehicle rear side.

[0263] The mechanism opening 418 is formed by the end of the rod support 402 on the vehicle right side, the end of the rear wall 404 on the vehicle right side, the end of the lower wall 410 on the vehicle right side, and the end of the front wall 430 on the vehicle right side. Therefore, the mechanism opening 418 opens toward the vehicle right. In addition, the vehicle right corresponds to one direction.

[0264] The mechanism opening space 420 is formed by the mechanism opening portion 418 , and communicates with the casing space 412 in the vehicle left-right direction Dc.

[0265] The support member extension 830 is connected to a portion on the vehicle right side of the support portion 800. The support member extension 830 is formed of metal in a plate shape extending in the vehicle front-rear direction Da and the vehicle up-down direction Db.

[0266] The housing fixing hole 490 is formed at an end portion on the vehicle right side of the front wall 430 and an end portion on the vehicle right side of the rear wall 404. Furthermore, the housing fixing hole 490 extends in the vehicle left-right direction Dc.

[0267] The member fixing holes 890 are formed at locations on the vehicle front side and the vehicle rear side of the support member extension 830. In addition, the member fixing holes 890 are formed at positions corresponding to the housing fixing holes 490. Therefore, the member fixing holes 890 and the housing fixing holes 490 are communicated.

[0268] Therefore, since the housing fixing hole 490 and the component fixing hole 890 are formed on the front side of the vehicle and the rear side of the vehicle, the fixing component 90 is located on the front side of the vehicle and the rear side of the vehicle. In addition, the fixing component 90 is inserted into the housing fixing hole 490 and the component fixing hole 890. Thus, the support component extension 830 is connected to the mechanism opening 418, and the housing 40 and the support component 80 are fixed. Furthermore, since the support component extension 830 is connected to the mechanism opening 418, the support component extension 830 blocks the mechanism opening space 420. In addition, the second elastic component 72 supported by the support part 800 is inserted into the housing space 412. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support component 80 and the housing 40.

[0269] As described above, the pedal device 1 of the 16th embodiment is constructed. In the 16th embodiment, the same effect as the 14th embodiment is also achieved. In addition, in the 14th embodiment, the housing 40 may also have a right side wall 408 instead of the left side wall 406. In this case, for example, the housing space 412 is a space formed by the rod support portion 402, the rear wall 404, the right side wall 408, the lower wall 410 and the front wall 430. In addition, the mechanism opening portion 418 is composed of the end portion on the left side of the vehicle in the rod support portion 402, the end portion on the left side of the vehicle in the rear wall 404, the end portion on the left side of the vehicle in the lower wall 410, and the end portion on the left side of the vehicle in the front wall 430. At this time, the mechanism opening portion 418 opens toward the left side of the vehicle. The left side of the vehicle corresponds to one direction. Furthermore, the support member extension portion 830 is connected to the portion on the left side of the vehicle in the support portion 800. Furthermore, the housing fixing hole 490 is formed at the end portion on the vehicle left side of the front wall 430 and at the end portion on the vehicle left side of the rear wall 404. Such a form may also be adopted.

[0270] (17th Implementation Method)

[0271] In the 17th embodiment, Fig.29 and Fig.30As shown, the housing 40 has a front wall 430 instead of the lower wall 410. In addition, the supporting member 80 does not have the panel hole 802 and the panel bolt 804, but instead, the housing 40 has the panel hole 802 and the panel bolt 804. Furthermore, the form of the housing space 412, the pedal opening 414, the mechanism opening 418, and the mechanism opening space 420 is different from the 14th embodiment. Furthermore, the supporting member 80 has a supporting member extension 830. In addition, the positions of the housing fixing hole 490, the member fixing hole 890, and the fixing member 90 are different from the 14th embodiment. Other than this, it is the same as the 14th embodiment.

[0272] The front wall 430 is connected to a portion of the rod support 402 on the vehicle front side, a portion of the left side wall 406 on the vehicle front side, and a portion of the right side wall 408 on the vehicle front side. In addition, a panel hole 802 is formed in the front wall 430. The panel bolt 804 is inserted into the panel hole 802 and the hole of the dash panel 200. Thus, the housing 40 is mounted on the dash panel 200. Therefore, the pedal device 1 is mounted on the dash panel 200.

[0273] The housing space 412 is a space defined by the rod support portion 402 , the rear wall 404 , the left side wall 406 , the right side wall 408 , and the front wall 430 .

[0274] The pedal opening 414 is formed by an end portion of the rear wall 404 on the lower side of the vehicle, an end portion of the left side wall 406 on the lower side of the vehicle, and an end portion of the right side wall 408 on the lower side of the vehicle.

Therefore, the mechanism opening 418 opens toward the vehicle lower side. In addition, the vehicle lower side corresponds to one direction.

[0276] The mechanism opening space 420 is formed by the mechanism opening portion 418 , and communicates with the casing space 412 in the vehicle up-down direction Db.

[0277] The support member extension 830 is connected to a portion on the vehicle lower side of the support portion 800. The support member extension 830 is formed of metal in a plate shape extending in the vehicle front-rear direction Da and the vehicle left-right direction Dc.

[0278] The housing fixing hole 490 is formed at an end portion on the vehicle lower side of the left side wall 406 and an end portion on the vehicle lower side of the right side wall 408. Furthermore, the housing fixing hole 490 extends in the vehicle up-down direction Db.

[0279] The member fixing hole 890 is formed at the vehicle left side and vehicle right side of the support member extension 830. In addition, the member fixing hole 890 is formed at a position corresponding to the housing fixing hole 490. Therefore, the member fixing hole 890 communicates with the housing fixing hole 490.

[0280] Therefore, since the housing fixing hole 490 and the component fixing hole 890 are formed on the lower side of the vehicle and the left side of the vehicle and the lower side of the vehicle and the right side of the vehicle, the fixing component 90 is located on the lower side of the vehicle and the left side of the vehicle and the lower side of the vehicle and the right side of the vehicle. In addition, the fixing component 90 is inserted into the housing fixing hole 490 and the component fixing hole 890. Thus, the support component extension 830 is connected to the mechanism opening 418, and the housing 40 and the support component 80 are fixed. Furthermore, since the support component extension 830 is connected to the mechanism opening 418, the support component extension 830 blocks the mechanism opening space 420. In addition, the second elastic component 72 supported by the support part 800 is inserted into the housing space 412. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support component 80 and the housing 40.

[0281] As described above, the pedal device 1 of the seventeenth embodiment is configured. In the seventeenth embodiment, the same effects as those of the fourteenth embodiment are achieved.

[0282] (Eighteenth Implementation Method)

[0283] In the 18th embodiment, if Fig.31 As shown in FIG. 1 , the support member 80 has a support member extension 830. The positions of the housing fixing hole 490, the member fixing hole 890, and the fixing member 90 are different from those in the fourteenth embodiment. Other than that, the present invention is the same as the fourteenth embodiment.

[0284] The support member extension 830 is connected to a portion of the support member 800 on the lower side of the vehicle. The support member extension 830 is formed of metal in a plate shape extending from the portion of the support member 800 on the lower side of the vehicle toward the rear of the vehicle. Furthermore, the support member extension 830 is located on the lower side of the vehicle than the lower wall 410 and is in contact with the lower wall 410. Alternatively, the support member extension 830 may be located on the upper side of the vehicle than the lower wall 410.

[0285] The housing fixing hole 490 is formed in the lower wall 410. In addition, the housing fixing hole 490 extends in the vehicle up-down direction Db. The component fixing hole 890 is formed in the support component extension 830 and is formed at a position corresponding to the housing fixing hole 490. Therefore, the component fixing hole 890 is connected to the housing fixing hole 490. Therefore, since the housing fixing hole 490 and the component fixing hole 890 are formed on the lower side of the vehicle, the fixing component 90 is located on the lower side of the vehicle. In addition, the fixing component 90 is inserted into the housing fixing hole 490 and the component fixing hole 890. Thus, the support component extension 830 is connected to the lower wall 410, and the housing 40 and the support component 80 are fixed. Furthermore, the support portion 800 blocks the mechanism opening space 420. In addition, the second elastic component 72 supported by the support portion 800 is inserted into the housing space 412 and the mechanism opening space 420. Thus, the reaction force generating mechanism 60 is accommodated in the housing space 412 and is surrounded by the support member 80 and the housing 40 .
