Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the study by the inventors, in the pedal simulator described in Patent Document 1, when the brake pedal rotates, the piston moves along the cylinder by the operating rod connected to the brake pedal, and the spring is compressed. However, in the pedal simulator described in Patent Document 1, minute substances such as wear powder generated by sliding between the piston and the cylinder and foreign substances entering from the outside of the cylinder may enter between the piston and the cylinder at the sliding portion. At this time, since the piston is fixed to the cylinder and the piston cannot move along the cylinder, the brake pedal cannot rotate.

A pedal, the pedal device further comprises a second holder and a facing portion facing the direction of deformation of the second elastic member, the first holder facing the direction of deformation of the second holder and the first elastic member, and moves toward the second holder due to the force from the pedal when the pedal rotates, the second holder moves toward the facing portion due to the force from the pedal when the pedal rotates, and the distance the first holder moves from when the pedal is pressed by the operator until the first holder and the second holder come into contact in the direction of deformation of the first elastic member is defined as the first distance (L1).This pedal device is designed such that when the pedal is pressed by the operator, the second distance (L2) is the distance the second holder travels from the time the pedal is pressed until the second holder contacts the opposing part in the direction of deformation of the second elastic member. When the second holder and the third guide are fixed, and the first holder moves the first distance, the absolute value of the vehicle's deceleration becomes greater than or equal to the first threshold, stopping the vehicle. When the first guide and the second guide are fixed, and the second holder moves the second distance, the absolute value of the vehicle's deceleration becomes greater than or equal to the second threshold, stopping the vehicle. Furthermore, the invention described in claim 16 is a pedal device comprising: a pedal (10) that rotates around a rotation axis (O) when pressed by an operator; a first elastic member (71) that deforms due to the force from the pedal when the pedal rotates, thereby generating a reaction force to the operator's pressing force; a second elastic member (72) that deforms due to the force from the pedal when the pedal rotates, thereby generating a reaction force to the operator's pressing force; and a first elastic member disposed on the pedal side and supporting one end of the first elastic member.

Furthermore, the invention described in claim 17 is a pedal device comprising: a pedal (10) that rotates around a rotation axis (O) when pressed by an operator; a first elastic member (71) that deforms due to the force from the pedal when the pedal rotates, thereby generating a reaction force to the operator's pressing force; a second elastic member (72) that deforms due to the force from the pedal when the pedal rotates, thereby generating a reaction force to the operator's pressing force; a first support part (610) positioned on the pedal side and supporting one end of the first elastic member; and a first elastic member extending from the first support part The first holder (61) has a first guide portion (614) extending in the direction of deformation of the elastic member, the second holder (62) has a second support portion (620) supporting the other end of the first elastic member, a second guide portion (622) extending from the second support portion in the direction of deformation of the first elastic member, and a third support portion (626) supporting one end of the second elastic member, the second holder (62) has a fourth support portion (44, 635) supporting the other end of the second elastic member, and a third guide portion (633) extending from the fourth support portion in the direction of deformation of the second elastic member, and the force from the pedal when the pedal rotates As a result, the first guide portion moves in the deformation direction of the first elastic member and moves relative to the second guide portion, sliding along the deformation direction of the second guide portion and the first elastic member, thereby deforming the first elastic member. Due to the force from the pedal when the pedal rotates, the second holder moves in the deformation direction of the second elastic member and moves relative to the third guide portion, sliding along the deformation direction of the third guide portion and the second elastic member, thereby deforming the second elastic member.

[0010] The embodiments will be described below with reference to the drawings. In the following embodiments, parts that are the same or equivalent to each other will be denoted by the same reference numeral, and their descriptions will be omitted.

[0011] (First Embodiment) The pedal device 1 of this embodiment is used, for example, as a brake pedal in a brake-by-wire system 150 that controls the brakes of a vehicle. First, this brake-by-wire system 150 will be described.

[0012] The brake-by-wire system 150, as shown in Figure 1, comprises wheel cylinders 131-134, an ECU 110, a brake circuit 120, and a pedal device 1.

[0013] Wheel cylinders 131-134 are located on each wheel of the vehicle. Brake pads (not shown) are also attached to each wheel cylinder 131-134.

[0014] The ECU110 includes a first ECU111 and a second ECU112. The first ECU111 includes a microcontroller and drive circuits (not shown). The first ECU111 controls the first brake circuit 121 of the brake circuit 120 (described later) based on signals from the pedal device 1 (described later). The second ECU112 includes a microcontroller and drive circuits (not shown). Furthermore, the second ECU112 controls the second brake circuit 122 of the brake circuit 120 (described later) based on signals from the pedal device 1 (described later).

[0015] 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 reciprocates the master piston 127 of the master cylinder 126 in the axial direction of the master cylinder 126. The second brake circuit 122 includes a solenoid valve (not shown). The second brake circuit 122 controls the hydraulic pressure of each wheel cylinder 131-134 by opening and closing the solenoid valve in response to a control signal from the second ECU 112.

[0016] Here, in order to explain the pedal device 1 below, the vehicle's longitudinal direction will be referred to as the vehicle longitudinal direction Da. The vehicle's vertical direction will be referred to as the vehicle vertical direction Db. The vehicle's left-right direction will be referred to as the vehicle left-right direction Dc. The front in the vehicle longitudinal direction Da will be referred to as the vehicle front. The rear in the vehicle longitudinal direction Da will be referred to as the vehicle rear. The upper part in the vehicle vertical direction Db will be referred to as the vehicle upper part. The lower part in the vehicle vertical direction Db will be referred to as the vehicle lower part. The left side in the vehicle left-right direction Dc will be referred to as the vehicle left side. The right side in the vehicle left-right direction Dc will be referred to as the vehicle right side.

[0017] As shown in Figures 2 to 5, the pedal device 1 comprises a pedal 10, a stroke sensor 30, a housing 40, and a reaction force generating mechanism 60.

[0018] Pedal 10 is operated by being pressed by the vehicle driver, as shown in Figures 2 and 3. The vehicle driver corresponds to the operator.

[0019] Specifically, the pedal 10 has a pedal portion 12, a lever portion 14, a lever projection 16, and a lever flange portion 18. The pedal portion 12 is pressed down by the driver. The lever portion 14 is connected to the pedal portion 12. The lever portion 14 rotates around the axis of rotation O when the pedal portion 12 is pressed down by the driver. The lever projection 16 is connected to the front side of the lever portion 14 and protrudes forward from the boundary with the lever portion 14. The lever flange portion 18 is connected to the lever projection 16 and protrudes from the boundary with the lever projection 16 in a direction perpendicular to the direction of projection of the lever projection 16.

[0020] The stroke sensor 30 is positioned, for example, on the rotation axis O of the lever portion 14. The stroke sensor 30 also includes a magnet, a yoke, a Hall element, etc. By detecting the rotation angle of the lever portion 14, the stroke sensor 30 detects the rotation angle and stroke amount of the pedal 10. Furthermore, the stroke sensor 30 outputs signals corresponding to the detected rotation angle and stroke amount of the pedal 10 to the first ECU 111 and the second ECU 112. The stroke sensor 30 detects the rotation angle and stroke amount of the pedal 10 by having a Hall element, but is not limited to this, and may also detect the rotation angle and stroke amount of the pedal 10 by having an MR element, etc. MR stands for Magneto Resistive. The stroke amount is, for example, the amount of movement of the pedal portion 12 in the vehicle's longitudinal direction Da.

[0021] The housing 40 is attached to the vehicle's dashboard panel 200 and, being formed in a closed-bottom cylindrical shape, houses a portion of the lever section 14, the stroke sensor 30, and the reaction force generating mechanism 60 described later. The dashboard panel 200 is a partition wall that separates the vehicle's interior from the exterior, such as the engine compartment, and is sometimes called a bulkhead. Outside the vehicle, in addition to the engine, other components such as the vehicle's battery and air conditioning system are also located.

[0022] Specifically, the housing 40 includes a housing bottom 42, a housing cylindrical portion 44, a panel mounting portion 46, a panel bolt 48, and a housing restricting portion 50.

[0023] The housing bottom 42 extends in the vehicle's longitudinal direction Da. The rotation axis O of the lever portion 14 and the stroke sensor 30 are attached to the housing bottom 42. Furthermore, the housing bottom 42 supports a portion of the lever portion 14 so that it can rotate around the rotation axis O, and also supports the stroke sensor 30.

[0024] The housing cylinder portion 44 corresponds to the fourth support portion and is connected to the end of the housing bottom portion 42 in the vehicle longitudinal direction Da, and extends downward from the boundary with the housing bottom portion 42. The housing cylinder portion 44 also houses a part of the lever portion 14, the stroke sensor 30, and the reaction force generating mechanism 60 described later.

[0025] The panel mounting portion 46 is connected to the front and upper ends of the housing bottom portion 42 and extends upward from the boundary with the housing bottom portion 42. The panel mounting portion 46 is also connected to the front and lower ends of the housing cylindrical portion 44 and extends downward from the boundary with the housing cylindrical portion 44. Holes are formed in the panel mounting portion 46, and the housing 40 is attached to the dash panel 200 by inserting panel bolts 48 into the holes in the panel mounting portion 46 and the holes in the dash panel 200.

[0026] The housing restrictor portion 50 is connected to the inner surface of the housing cylindrical portion 44 located on the front side of the vehicle, and protrudes from that inner surface toward the rear of the vehicle. The housing restrictor portion 50 also has a hole into which the guide member 63, described later, is inserted.

[0027] The reaction force generating mechanism 60 generates a reaction force in response to the driver's pedaling force applied to the pedal portion 12. Specifically, as shown in Figure 4, 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.

[0028] The first holder 61 is formed of, for example, resin. The first holder 61 also includes a first support portion 610, a holder restricting portion 612, and a first guide portion 614. Although the first holder 61 is formed of resin, it is not limited to this and may be formed of, for example, metal.

[0029] The first support portion 610 is formed in the shape of a plate, for example, extending in a direction perpendicular to the vehicle's longitudinal direction Da. The holder restricting portion 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 in the shape of a cylinder, extending toward the front of the vehicle from the side of the first support portion 610 opposite to the holder restricting portion 612, as shown in Figures 4 and 5.

[0030] The second holder 62 is formed of, for example, resin. The second holder 62 also includes a second support portion 620, a second guide portion 622, a holder cylindrical portion 624, and a third support portion 626. Although the second holder 62 is formed of resin, it is not limited to this and may be formed of, for example, metal.

[0031] The second support portion 620 is formed in a plate shape extending in a direction perpendicular to the vehicle's longitudinal direction Da, and is also formed in an annular shape.

[0032] The second guide portion 622 is connected to the inside of the second support portion 620 in a direction perpendicular to the vehicle's longitudinal direction Da, and is formed in a cylindrical shape extending toward the rear of the vehicle from the boundary with the second support portion 620. In addition, a part of the second guide portion 622 is inserted into the hole of the first guide portion 614. This restricts the movement of the first guide portion 614 and the second guide portion 622 in the vehicle's vertical direction Db from each other. Furthermore, because the first guide portion 614 and the second guide portion 622 extend in the vehicle's longitudinal direction Da, the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 slide along the vehicle's longitudinal direction Da.

[0033] The holder cylinder portion 624 is connected to the outside of the second support portion 620 in a direction perpendicular to the vehicle's longitudinal direction Da, and extends in the rearward direction of the vehicle from the boundary with the second support portion 620.

[0034] The third support portion 626 is formed in a plate shape extending in a direction perpendicular to the vehicle's longitudinal direction Da, and is also formed in an annular shape. Furthermore, the third support portion 626 is connected to the holder cylinder portion 624 on the side opposite to the second support portion 620, and is therefore positioned further rearward than the second support portion 620. In addition, a part of the first guide portion 614 is inserted into the hole in the third support portion 626.

[0035] The guide member 63 includes a third guide portion 633. The third guide portion 633 is made of, for example, metal. The third guide portion 633 is also formed in a cylindrical shape that extends in the vehicle longitudinal direction Da. Furthermore, a part of the third guide portion 633 is inserted into the holes of the housing cylindrical portion 44 and the housing restricting portion 50. Also, a part of the third guide portion 633 is inserted into the hole of the second guide portion 622. As a result, the movement of the second guide portion 622 and the third guide portion 633 in the vehicle vertical direction Db is restricted from each other. In addition, because the second guide portion 622 and the third guide portion 633 extend in the vehicle longitudinal direction Da, the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 slide along the vehicle longitudinal direction Da.

[0036] Here, the first distance L1 is the distance between the first holder 61 and the second holder 62 in the vehicle longitudinal direction Da, and is the distance traveled by the first holder 61 from the time the pedal 10 is pressed by the vehicle driver until the first holder 61 and the second holder 62 come into contact. For example, here, the first distance L1 is the distance from the first guide portion 614 to the second support portion 620 in the vehicle longitudinal direction Da. The second distance L2 is the distance between the second holder 62 and the opposing portion opposite to the direction of movement of the second holder 62 in the vehicle longitudinal direction Da, and is the distance traveled by the second holder 62 from the time the pedal 10 is pressed by the vehicle driver until the second holder 62 and its opposing portion come into contact. For example, here, the second distance L2 is the distance from the second holder 62 to the housing restricting portion 50 in the vehicle longitudinal direction Da.

[0037] 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 elastically deforms in the vehicle's longitudinal direction Da. A first guide portion 614 and a second guide portion 622 are arranged inside the first elastic member 71. This restricts the movement of the first elastic member 71 in the vehicle's vertical direction Db. Furthermore, the first elastic member 71 is supported by the first support portion 610 and the second support portion 620 by contacting them. When the pedal portion 12 is not pressed by the driver, the first elastic member 71 is elastically deformed and, in this case, compressed. Note that, while the first elastic member 71 is elastically deformed when the pedal portion 12 is not pressed by the driver here, it is not limited to this and may not be elastically deformed. In this case, the length of the first elastic member 71 is its free length.

[0038] The second elastic member 72 is, for example, a coil spring and elastically deforms in the vehicle longitudinal direction Da. The second elastic member 72 is supported by the second support portion 620 and the housing cylindrical portion 44 by contacting the third support portion 626 and the housing cylindrical portion 44. Furthermore, the housing restricting portion 50 and the holder cylindrical portion 624 are arranged inside the second elastic member 72. This restricts the movement of the second elastic member 72 in the vehicle vertical direction Db. When the second elastic member 72 is projected toward the first elastic member 71 in the vehicle vertical direction Db, the projected second elastic member 72 and the first elastic member 71 overlap. When the pedal portion 12 is not pressed by the driver, the second elastic member 72 is elastically deformed and, in this case, compressed. Note that, while the second elastic member 72 is elastically deformed when the pedal portion 12 is not pressed by the driver, it is not limited to this and may not be elastically deformed. In this case, the length of the second elastic member 72 is its free length.

[0039] The third elastic member 73 is, for example, a coil spring and is elastically deformable in the vehicle's longitudinal direction Da. The third elastic member 73 is supported by the first support portion 610 by being in contact with it. Furthermore, a holder restricting portion 612 is positioned inside the third elastic member 73. This restricts the movement of the third elastic member 73 in the vehicle's vertical direction Db. When the pedal portion 12 is not pressed by the driver, a part of the lever projection 16 is inserted inside the third elastic member 73, causing the third elastic member 73 to be in contact with the lever flange portion 18. At this time, the third elastic member 73 is elastically deformed and, in this case, compressed. Note that, while the third elastic member 73 is elastically deformed when the pedal portion 12 is not pressed by the driver, it is not limited to this and may not be elastically deformed. In this case, the length of the third elastic member 73 is its free length. Furthermore, while the third elastic member 73 and the lever flange 18 are in contact when the pedal portion 12 is not pressed by the driver, this is not limited to this. When the pedal portion 12 is not pressed by the driver, the third elastic member 73 and the lever flange 18 may be separated, resulting in no contact between the third elastic member 73 and the lever flange 18.

[0040] As described above, the brake-by-wire system 150 is configured as described. Next, the operation of the pedal device 1 will be explained.

[0041] When the driver of the vehicle presses the pedal portion 12, the lever portion 14 rotates together with the pedal portion 12 around the rotation axis O. As a result, the force from the pedal portion 12 is transmitted to the third elastic member 73 via the lever flange portion 18, causing the third elastic member 73 to be compressed. The force from the pedal portion 12 is also transmitted to the first holder 61. As a result, the first holder 61 moves in the forward direction of the vehicle, causing the inner surface of the first guide portion 614 to slide against the outer surface of the second guide portion 622 along the forward direction of the vehicle, and the first elastic member 71 to be compressed by being pressed against the first support portion 610. Furthermore, the force from the pedal portion 12 is transmitted to the second holder 62. As a result, the second holder 62 moves in the forward direction of the vehicle, causing the inner surface of the second guide portion 622 to slide against the outer surface of the third guide portion 633 along the forward direction of the vehicle, and the second elastic member 72 to be compressed by being pressed against the third support portion 626. Therefore, a reaction force is generated by the restoring force produced when the first elastic member 71, the second elastic member 72, and the third elastic member 73 are compressed. Due to this reaction force, the pedal device 1 can obtain the same reaction force as when it is connected to the master cylinder 126, i.e., when a hydraulic reaction force is obtained, even though the mechanical connection between the pedal 10 and the master cylinder 126 has been eliminated.

[0042] At this time, the stroke sensor 30 detects the rotation angle of the lever portion 14, thereby detecting the rotation angle and stroke amount of the pedal portion 12. The stroke sensor 30 also outputs the detected rotation angle and stroke amount of the pedal portion 12 to the first ECU 111 and the second ECU 112.

[0043] At this time, the first ECU 111 rotates the motor 123 by supplying power to it, for example. This drives the gear mechanism 125, causing the master piston 127 to move. As a result, the hydraulic pressure of the brake fluid supplied from the reservoir 124 to the master cylinder 126 increases. This increased hydraulic pressure is supplied to the second brake circuit 122.

[0044] Furthermore, the second ECU 112 supplies power to, for example, a solenoid valve (not shown) in the second brake circuit 122. This opens the solenoid valve in the second brake circuit 122. As a result, the brake fluid supplied to the second brake circuit 122 is supplied to each wheel cylinder 131-134. Consequently, the brake pads attached to the wheel cylinders 131-134 rub against the corresponding brake discs. Thus, each wheel is braked, and the vehicle decelerates. At this time, the second ECU 112 may perform ABS control, VSC control, collision avoidance control, and regenerative braking coordinated control, etc., based on signals from the stroke sensor 30 and signals from other electronic control devices (not shown). ABS stands for Anti-lock Braking System. VSC stands for Vehicle Stability Control.

[0045] Here, for example, when the second holder 62 and the third guide 633 are fixed, when the first holder 61 moves a first distance L1, the absolute value of the vehicle's deceleration becomes equal to or greater than the first threshold, and the vehicle stops. Also, when the first guide 614 and the second guide 622 are fixed, when the second holder 62 moves a second distance L2, the absolute value of the vehicle's deceleration becomes equal to or greater than the second threshold, and the vehicle stops. The first and second thresholds are set by experiments, simulations, etc., to ensure that a sufficient amount of vehicle deceleration is obtained.

[0046] When the vehicle driver stops pressing the pedal portion 12, the restoring force of the first elastic member 71 and the second elastic member 72 pushes the first holder 61 and the second holder 62 back toward the rear of the vehicle. As a result, the inner surface of the first guide portion 614 slides along the rear of the vehicle with the outer surface of the second guide portion 622, and the inner surface of the second guide portion 622 slides along the rear of the vehicle with the outer surface of the third guide portion 633. In addition, the restoring force of the third elastic member 73 pushes the lever flange portion 18 back. Therefore, the position of the pedal 10 returns to the initial position when the pedal portion 12 is not being pressed by the vehicle driver.

[0047] In this manner, the pedal device 1 operates. This pedal device 1 prevents the pedal 10 from becoming unable to rotate when it is pressed. Next, we will explain how this prevention of the pedal 10 becoming unable to rotate is achieved.

[0048] Here, we will explain the case in which the pedal 10 cannot be rotated using the comparative first pedal device 901 and the comparative second pedal device 902. To this end, we will first explain the comparative first pedal device 901. As shown in Figure 6, the comparative first pedal device 901 includes a comparative first guide part 911, a comparative first support part 921, a comparative second support part 931, a comparative first elastic member 941, a comparative second elastic member 951, and a comparative pedal (not shown).

[0049] The first comparative guide section 911 is formed in a bottomed cylindrical shape and accommodates the first comparative support section 921, the second comparative support section 931, the first comparative elastic member 941, and the second comparative elastic member 951, which will be described later. The first comparative support section 921 and the second comparative support section 931 are formed in a plate shape that extends in a direction perpendicular to the left-right direction of the paper. In addition, the sides of the first comparative support section 921 and the second comparative support section 931 that extend in the left-right direction of the paper slide along the inner surface of the first comparative guide section 911 and the left-right direction of the paper. Furthermore, the second comparative support section 931 is positioned to the left of the paper than the first comparative support section 921. The first comparative elastic member 941 is positioned between the first comparative support section 921 and the second comparative support section 931 and is supported by the first comparative support section 921 and the second comparative support section 931. The comparative second elastic member 951 is positioned between the comparative second support portion 931 and the bottom of the comparative first guide portion 911, and is supported by the bottom of the comparative second support portion 931 and the comparative first guide portion 911. Furthermore, the comparative first elastic member 941 and the comparative second elastic member 951 are elastically deformable in the left-right direction of the paper.

[0050] In the first comparative pedal device 901, for example, minute objects or foreign objects entering from the outside may get trapped between the first comparative support portion 921 and the first comparative guide portion 911 at the sliding part. At this time, the first comparative support portion 921 and the first comparative guide portion 911 become fixed, and the first comparative support portion 921 is unable to move along the first comparative guide portion 911. Consequently, the first comparative elastic member 941 can no longer elastically deform, and the force of the comparative pedal (not shown) is no longer transmitted to the second comparative support portion 931. Therefore, the second comparative support portion 931 is also unable to move along the first comparative guide portion 911. As a result, the comparative pedal (not shown) is unable to rotate. In addition, the reaction forces from the first comparative elastic member 941 and the second comparative elastic member 951 are no longer transmitted to the comparative pedal (not shown). In this context, "fine particles" refer to, for example, wear particles generated by sliding between the comparative first support part 921, the comparative second support part 931, and the comparative first guide part 911.

[0051] Next, the comparative second pedal device 902 will be described. As shown in Figure 7, the comparative second pedal device 902 includes a comparative third support part 912, a comparative fourth support part 922, and a comparative fifth support part 932. The comparative second pedal device 902 also includes a comparative first cylindrical part 942, a comparative second cylindrical part 952, a comparative second guide part 962, a comparative third elastic member 972, a comparative fourth elastic member 982, and a comparative pedal (not shown).

[0052] The comparative third support portion 912, comparative fourth support portion 922, and comparative fifth support portion 932 are formed in a plate shape extending in a direction perpendicular to the left-right direction of the paper. The comparative fourth support portion 922 is positioned to the left of the paper than the comparative third support portion 912. The comparative fifth support portion 932 is positioned to the left of the paper than the comparative fourth support portion 922. The comparative first cylindrical portion 942 is connected to the comparative third support portion 912 and extends to the left of the paper from the boundary with the comparative third support portion 912. The comparative second cylindrical portion 952 is connected to the comparative fourth support portion 922 and extends to the left of the paper from the boundary with the comparative fourth support portion 922. The comparative second guide portion 962 is connected to the comparative fifth support portion 932 and is formed in a columnar shape extending to the right of the paper from the comparative fifth support portion 932. Furthermore, a portion of the second comparative guide portion 962 is inserted into the holes of the first comparative cylindrical portion 942 and the second comparative cylindrical portion 952. In addition, the outer surface of the second comparative guide portion 962 that extends in the left-right direction of the paper slides along the left-right direction of the paper with the inner surface of the first comparative cylindrical portion 942 that extends in the left-right direction of the paper. The third comparative elastic member 972 is positioned between the third comparative support portion 912 and the fourth comparative support portion 922 and is supported by the third comparative support portion 912 and the fourth comparative support portion 922. The fourth comparative elastic member 982 is positioned between the fourth comparative support portion 922 and the fifth comparative support portion 932 and is supported by the fourth comparative support portion 922 and the fifth comparative support portion 932. Furthermore, the comparative third elastic member 972 and the comparative fourth elastic member 982 are elastically deformed in the left-right direction of the paper.

[0053] Furthermore, in the comparative second pedal device 902, for example, minute objects or foreign objects entering from the outside may get trapped between the comparative first cylindrical portion 942 and the comparative second guide portion 962 at the sliding part. At this time, the comparative first cylindrical portion 942 and the comparative second guide portion 962 become fixed, and the comparative first cylindrical portion 942 is unable to move along the comparative second guide portion 962. Consequently, the comparative third elastic member 972 is unable to elastically deform, and the force of the comparative pedal (not shown) is no longer transmitted to the comparative fourth support portion 922 and the comparative second cylindrical portion 952. Therefore, the comparative second cylindrical portion 952 is also unable to move along the comparative second guide portion 962. As a result, the comparative pedal (not shown) is unable to rotate. In addition, the reaction forces from the comparative third elastic member 972 and the comparative fourth elastic member 982 are no longer transmitted to the comparative pedal (not shown). In this context, "fine particles" refer to, for example, wear particles generated by sliding between the comparative first cylindrical section 942, the comparative second cylindrical section 952, and the comparative second guide section 962.

[0054] In contrast, in the pedal device 1 of this embodiment, the force from the pedal 10 when the pedal 10 rotates causes the first guide portion 614 to slide with the second guide portion 622 along the vehicle longitudinal direction Da, thereby deforming the first elastic member 71. Also, the force from the pedal 10 when the pedal 10 rotates causes the second guide portion 622 of the second holder 62 to slide with the third guide portion 633 along the vehicle longitudinal direction Da, thereby deforming the second elastic member 72. The vehicle longitudinal direction Da corresponds to the deformation direction of the first elastic member 71 and the deformation direction of the second elastic member 72.

[0055] As a result, when the second holder 62 and the third guide portion 633 are fixed, the force from the pedal 10 when the pedal 10 rotates causes the first guide portion 614 and the second guide portion 622 to slide along the vehicle's longitudinal direction Da. Also, when the first guide portion 614 and the second guide portion 622 are fixed, the force from the pedal 10 when the pedal 10 rotates causes the second guide portion 622 and the third guide portion 633 of the second holder 62 to slide along the vehicle's longitudinal direction Da. Therefore, even if one of the two sliding parts is fixed, sliding occurs at the other sliding part. This prevents the pedal 10 from becoming unable to rotate when it is pressed.

[0056] Furthermore, the first embodiment also provides the following effects.

[0057] [1-1] The first guide portion 614 is formed in a cylindrical shape. The second guide portion 622 is also formed in a cylindrical shape. This makes it easier for the shapes of the first guide portion 614 and the second guide portion 622 to correspond to each other even when they rotate around their axes when assembling them. As a result, when assembling the first guide portion 614 and the second guide portion 622, the direction of rotation of the first guide portion 614 and the second guide portion 622 around their axes does not need to be considered. Therefore, it is easier to assemble the first guide portion 614 and the second guide portion 622.

[0058] Furthermore, the third guide portion 633 is formed in a cylindrical shape. This makes it easier for the shapes of the second guide portion 622 and the third guide portion 633 to correspond to each other even when they rotate around their axis when assembling them. As a result, when assembling the second guide portion 622 and the third guide portion 633, the direction of rotation of the second guide portion 622 and the third guide portion 633 around their axis does not need to be considered. Therefore, the assembly of the second guide portion 622 and the third guide portion 633 is made easier.

[0059] [1-2] The deformation direction of the first elastic member 71, the second elastic member 72, and the third elastic member 73 is a linear direction perpendicular to the rotation axis O, in this case the vehicle longitudinal direction Da. As a result, the first elastic member 71, the second elastic member 72, and the third elastic member 73 are easily compressed without tilting, thus generating a stable reaction force.

[0060] [1-3] When the second elastic member 72 is projected onto the vehicle's vertical direction Db, the projected second elastic member 72 and the first elastic member 71 overlap. Note that the vehicle's vertical direction Db corresponds to the direction perpendicular to the deformation direction of the second elastic member 72.

[0061] As a result, the size of the reaction force generating mechanism 60 in the vehicle's longitudinal direction Da is reduced compared to the case where the second elastic member 72 and the first elastic member 71 projected in the vehicle's vertical direction Db do not overlap. Therefore, an increase in the size of the pedal device 1 is suppressed.

[0062] [1-4] A space is formed inside the first elastic member 71, and the first guide portion 614 and the second guide portion 622 are positioned inside the first elastic member 71. As a result, the size of the first holder 61 and the second holder 62 in the vehicle vertical direction Db is reduced compared to the case where the first guide portion 614 and the second guide portion 622 are positioned outside the first elastic member 71. Thus, an increase in the size of the pedal device 1 is suppressed. In addition, since the first guide portion 614 and the second guide portion 622 are surrounded by the first elastic member 71, it becomes difficult for foreign matter from the outside to enter the sliding parts of the first guide portion 614 and the second guide portion 622.

[0063] [1-5] A space is formed inside the second elastic member 72, and the second guide portion 622 and the third guide portion 633 are positioned inside the second elastic member 72. As a result, the size of the second holder 62 in the vehicle vertical direction Db is smaller compared to the case where the second guide portion 622 and the third guide portion 633 are positioned outside the second elastic member 72. Thus, an increase in the size of the pedal device 1 is suppressed. In addition, since the second guide portion 622 and the third guide portion 633 are surrounded by the second elastic member 72, it becomes difficult for foreign matter from the outside to enter the sliding parts of the second guide portion 622 and the third guide portion 633.

[0064] [1-6] The first guide portion 614 and the second guide portion 622 restrict the movement of the first elastic member 71 in the vehicle vertical direction Db. As a result, the first elastic member 71 is less likely to move in the vehicle vertical direction Db, and friction with the first support portion 610 and the second support portion 620 that support the first elastic member 71 is reduced. Therefore, the amount of wear on the first elastic member 71, the first support portion 610 and the second support portion 620 is reduced. In addition, because the first elastic member 71 is less likely to move in the vehicle vertical direction Db, the first elastic member 71 is more likely to be compressed without tilting, thus generating a stable reaction force. The first guide portion 614 and the second guide portion 622 correspond to restricting portions.

[0065] [1-7] The holder cylindrical portion 624 and the housing restricting portion 50 restrict the movement of the second elastic member 72 in the vehicle vertical direction Db. As a result, the second elastic member 72 is less likely to move in the vehicle vertical direction Db, and friction with the third support portion 626 and the housing cylindrical portion 44 that support the second elastic member 72 is reduced. Therefore, the amount of wear on the second elastic member 72, the third support portion 626 and the housing cylindrical portion 44 is reduced. In addition, because the second elastic member 72 is less likely to move in the vehicle vertical direction Db, it is easier for the second elastic member 72 to be compressed without tilting, thus generating a stable reaction force. The holder cylindrical portion 624 and the housing restricting portion 50 correspond to the restricting portion.

[0066] [1-8] The third guide portion 633 contains metal. As metal is a relatively deformation-resistant material, damage to the third guide portion 633 and subsequent failure to slide with the second guide portion 622 is suppressed. The housing 40 also contains resin. Therefore, when forming the housing 40 connected to the third guide portion 633, integral molding can be performed, for example, by injection molding. Furthermore, the second guide portion 622 contains resin. As a result, the coefficient of friction between the second guide portion 622 and the third guide portion 633 is reduced compared to the case where the second guide portion 622 and the third guide portion 633 are made of metal. Therefore, the frictional force between the second guide portion 622 and the third guide portion 633 is reduced, which suppresses the generation of noise associated with friction between the second guide portion 622 and the third guide portion 633. In addition, because resin has a relatively low specific gravity, the weight of the second guide portion 622 is suppressed, making the second guide portion 622 lighter. Therefore, by suppressing the weight increase of the pedal device 1, the pedal device 1 can be made lighter.

[0067] [1-9] The first elastic member 71, the second elastic member 72, and the third elastic member 73 are coil springs. As a result, the effect of temperature on the elastic modulus of the first elastic member 71, the second elastic member 72, and the third elastic member 73 is relatively small. In addition, the first elastic member 71, the second elastic member 72, and the third elastic member 73 have relatively high oil resistance, solvent resistance, and chemical resistance. Therefore, the first elastic member 71, the second elastic member 72, and the third elastic member 73 are relatively resistant to deterioration, resulting in the generation of a stable reaction force.

[0068] [1-10] Pedal 10 is a brake pedal used in a vehicle. In the pedal device 1 of this embodiment, when pedal 10 is pressed, the inability of pedal 10 to rotate is suppressed, thereby suppressing the inability of the vehicle to brake.

[0069] [1-11] The first guide portion 614 faces the second support portion 620 in the vehicle longitudinal direction Da, and moves toward the second support portion 620 due to the force from the pedal 10 when the pedal 10 rotates. The second support portion 620 and the third support portion 626 face the housing cylindrical portion 44 in the vehicle longitudinal direction Da, and move toward the housing cylindrical portion 44 due to the force from the pedal 10 when the pedal 10 rotates. Furthermore, when the first holder 61 moves a first distance L1, the absolute value of the vehicle's deceleration becomes greater than or equal to a threshold, and the vehicle stops. Furthermore, when the second holder 62 moves a second distance L2, the absolute value of the vehicle's deceleration becomes greater than or equal to a threshold, and the vehicle stops. As described above, the first threshold and the second threshold are set by experiments, simulations, etc., so that a sufficient amount of vehicle deceleration is obtained.

[0070] As a result, even if one of the two sliding parts is fixed, the pedal 10 rotates in a way that allows the vehicle to decelerate sufficiently. This prevents the vehicle from losing braking power.

[0071] [1-12] The housing 40 that houses the reaction force generating mechanism 60 is located on the passenger compartment side of the dash panel 200 that separates the passenger compartment from the outside of the vehicle. As a result, moisture and oil from the engine compartment are less likely to enter the passenger compartment, and therefore less likely to adhere to the first elastic member 71, second elastic member 72, and third elastic member 73 of the reaction force generating mechanism 60. In addition, external factors from the engine compartment, such as light and heat, are less likely to enter the passenger compartment. Therefore, the first elastic member 71, second elastic member 72, and third elastic member 73 are less likely to deteriorate, and thus their durability is improved.

[0072] [1-13] The first guide section 614 and the second guide section 622 mutually restrict the movement of the vehicle in the vertical direction Db. The vehicle vertical direction Db corresponds to the direction perpendicular to the deformation direction of the first elastic member 71.

[0073] As a result, the first guide portion 614 and the second guide portion 622 are prevented from entering the inside of the first elastic member 71, thereby preventing interference with the elastic deformation of the first elastic member 71. In addition, the first guide portion 614 and the second guide portion 622 are prevented from interlocking with the first elastic member 71, thus preventing damage to the first elastic member 71. Therefore, the restoring force of the first elastic member 71 is prevented from being transmitted to the pedal 10, thus preventing the pedal 10 from failing to return to its original position.

[0074] Furthermore, the second holder 62 and the third guide portion 633 mutually restrict movement in the vehicle's vertical direction Db. Note that the vehicle's vertical direction Db corresponds to a direction perpendicular to the deformation direction of the second elastic member 72.

[0075] As a result, the second holder 62 and the third guide portion 633 are prevented from entering the inside of the second elastic member 72, thereby preventing interference with the elastic deformation of the second elastic member 72. Furthermore, since the second holder 62 and the third guide portion 633 are prevented from interlocking with the second elastic member 72, damage to the second elastic member 72 is also prevented. Therefore, the restoring force of the second elastic member 72 is prevented from being transmitted to the pedal 10, thus preventing the pedal 10 from failing to return to its original position.

[0076] [1-14] The first elastic member 71, the second elastic member 72, and the third elastic member 73 are elastically deformed, and in this case, compressed, when the pedal 10 is not pressed by the driver of the vehicle. As a result, even if the first elastic member 71, the second elastic member 72, and the third elastic member 73 are elastically deformed when the pedal 10 is pressed by the driver of the vehicle and break, the restoring force generated by them returning to their respective free lengths makes it easier for the pedal 10 to return to its original position.

[0077] (Second Embodiment) In the second embodiment, as shown in Figure 8, the shape of the pedal 10 differs from that of the first embodiment. Also, the shape of the second holder 62 differs from that of the first embodiment. Furthermore, the shape of the guide member 63 differs from that of the first embodiment. In addition, the housing 40 does not have a housing restricting portion 50. Other than these, it is the same as the first embodiment.

[0078] The pedal 10 has a lever plate portion 20 instead of a lever projection 16 and a lever flange portion 18. The lever plate portion 20 is formed in a plate shape and is connected to the front side of the lever portion 14. The lever plate portion 20 is in contact with the side of the third elastic member 73 opposite to the first support portion 610. At this time, the third elastic member 73 is not elastically deformed. Therefore, when the pedal portion 12 is not pressed by the driver, the length of the third elastic member 73 is its free length. Note that, as stated here, when the pedal portion 12 is not pressed by the driver, the third elastic member 73 is not elastically deformed, but is not limited to this, and may be elastically deformed. Also, when the pedal portion 12 is not pressed by the driver, the third elastic member 73 and the lever plate portion 20 are in contact, but is not limited to this. When the pedal portion 12 is not pressed by the driver, the third elastic member 73 and the lever plate portion 20 are separated, so the third elastic member 73 and the lever plate portion 20 may not be in contact.

[0079] The second holder 62 does not include the holder cylinder portion 624. Furthermore, the second support portion 620 and the third support portion 626 of the second holder 62 are integrated.

[0080] The guide member 63 has a guide member bottom 635 in addition to the third guide portion 633. The guide member bottom 635 corresponds to the fourth support portion. The guide member bottom 635 is formed of, for example, resin. Furthermore, the guide member bottom 635 is connected to the third guide portion 633. The guide member bottom 635 is also connected to the inner surface of the housing cylindrical portion 44 located on the front side of the vehicle. Furthermore, the guide member bottom 635 supports the second elastic member 72 by contacting the side of the second elastic member 72 opposite to the third support portion 626.

[0081] As described above, the pedal device 1 of the second embodiment is configured as described above. This second embodiment also provides the same effects as the first embodiment.

[0082] (Third embodiment) In the third embodiment, as shown in Figure 9, the shapes of the second holder 62 and the third guide portion 633 differ from those of the second embodiment. Otherwise, it is the same as the second embodiment.

[0083] The second holder 62 has a second support portion 620, a third support portion 626, and a second guide portion 622. The second support portion 620 is formed in a plate shape extending in the vehicle vertical direction Db, integrally with the third support portion 626. The second guide portion 622 is made of, for example, metal. The second guide portion 622 is connected to the second support portion 620 and is formed in a cylindrical shape extending toward the rear of the vehicle from the boundary with the second support portion 620. A part of the second guide portion 622 is inserted into a hole in the first guide portion 614. As a result, the movement of the first guide portion 614 and the second guide portion 622 in the vehicle vertical direction Db is restricted from each other. Furthermore, because the first guide portion 614 and the second guide portion 622 extend in the vehicle longitudinal direction Da, the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 slide along the vehicle longitudinal direction Da.

[0084] The third guide portion 633 is made of resin instead of metal. Also, the third guide portion 633 is formed in a cylindrical shape extending in the vehicle's longitudinal direction Da, instead of being cylindrical. As a result, the guide member 63 is formed in a bottomed cylindrical shape. The second support portion 620 and the third support portion 626 are inserted into the hole in the third guide portion 633. As a result, the movement of the second support portion 620, the third support portion 626, and the third guide portion 633 in the vehicle's vertical direction Db is restricted. Furthermore, because the third guide portion 633 extends in the vehicle's longitudinal direction Da, the sides of the second support portion 620 and the third support portion 626, which extend in the vehicle's longitudinal direction Da, slide against the inner surface of the third guide portion 633 along the vehicle's longitudinal direction Da.

[0085] As described above, the pedal device 1 of the third embodiment is configured as described above. This third embodiment also provides the same effects as the second embodiment.

[0086] (Fourth Embodiment) In the fourth embodiment, as shown in Figure 10, the shape of the pedal 10 differs from that of the third embodiment. In addition, the reaction force generating mechanism 60 has a third holder 65 in addition to the first holder 61, second holder 62, guide member 63, first elastic member 71, second elastic member 72, and third elastic member 73. Furthermore, the shape of the first holder 61 differs from that of the first embodiment. Other than these differences, it is the same as the third embodiment.

[0087] The pedal 10 has a lever projection 16 instead of a lever plate 20. The lever projection 16 is connected to the front side of the lever portion 14 and protrudes forward from the boundary with the lever portion 14.

[0088] The third holder 65 is formed of, for example, resin. The third holder 65 also has a holder support portion 650 and a fourth guide portion 654.

[0089] The holder support portion 650 is formed, for example, in the shape of a plate extending in a direction perpendicular to the vehicle's longitudinal direction Da. The holder support portion 650 is in contact with the lever projection 16. However, it is not limited to the holder support portion 650 and the lever projection 16 being in contact when the pedal portion 12 is not pressed by the driver. When the pedal portion 12 is not pressed by the driver, the holder support portion 650 and the lever projection 16 may be separated, resulting in no contact between the holder support portion 650 and the lever projection 16.

[0090] The fourth guide portion 654 is formed in a cylindrical shape, for example, extending forward from the end face of the holder support portion 650 opposite to the lever projection 16. The fourth guide portion 654 is also positioned inside the third elastic member 73. This restricts the movement of the third elastic member 73 in the vehicle's vertical direction Db.

[0091] The first holder 61 has a fifth guide portion 615 instead of a holder restricting portion 612. The fifth guide portion 615 is made of, for example, metal. The fifth guide portion 615 is connected to the first support portion 610 and is formed in a cylindrical shape that extends in the rearward direction of the vehicle from the boundary with the first support portion 610. A part of the fifth guide portion 615 is inserted into a hole in the fourth guide portion 654. As a result, the movement of the fourth guide portion 654 and the fifth guide portion 615 in the vehicle vertical direction Db is restricted from each other. Furthermore, because the fourth guide portion 654 and the fifth guide portion 615 extend in the vehicle longitudinal direction Da, the inner surface of the fourth guide portion 654 and the outer surface of the fifth guide portion 615 slide along the vehicle longitudinal direction Da.

[0092] As described above, the pedal device 1 of the fourth embodiment is configured as described above. This fourth embodiment also provides the same effects as the third embodiment.

[0188] (27th embodiment) In the 27th embodiment, as shown in Figure 35, the shapes of the first guide section 614, the second guide section 622, and the third guide section 633 differ from those of the first embodiment. Otherwise, it is the same as the first embodiment.

[0189] Here, let's assume that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected in the vehicle's vertical direction Db toward the sliding portion between the second guide portion 622 and the third guide portion 633. In this case, in the first embodiment, the sliding portion between the first guide portion 614 and the second guide portion 622 projected toward the vehicle's vertical direction Db overlaps with the sliding portion between the second guide portion 622 and the third guide portion 633. Furthermore, both when the pedal portion 12 is not pressed by the driver and when the pedal portion 12 is pressed by the driver, the projected sliding portion between the first guide portion 614 and the second guide portion 622 overlaps with the sliding portion between the second guide portion 622 and the third guide portion 633. Note that the sliding portion between the first guide portion 614 and the second guide portion 622 corresponds to the contact portion between the first guide portion 614 and the second guide portion 622. Furthermore, the sliding portion between the second guide portion 622 and the third guide portion 633 corresponds to the contact portion between the second guide portion 622 and the third guide portion 633.

[0190] In contrast, in the 27th embodiment, the sliding portion between the first guide portion 614 and the second guide portion 622 projected in the vehicle's vertical direction Db does not overlap with the sliding portion between the second guide portion 622 and the third guide portion 633. Furthermore, when the pedal portion 12 is not being pressed by the driver, and when the pedal portion 12 is being pressed by the driver, the projected sliding portion between the first guide portion 614 and the second guide portion 622 does not overlap with the sliding portion between the second guide portion 622 and the third guide portion 633.

[0191] As described above, the pedal device 1 of the 27th embodiment is configured. This 27th embodiment also provides the same effects as the first embodiment. Furthermore, the 27th embodiment also provides the effects described below.

[0192] [3] Furthermore, it is assumed that the sliding portion between the first guide portion 614 and the second guide portion 622, projected in the vehicle's vertical direction Db, overlaps with the sliding portion between the second guide portion 622 and the third guide portion 633. Also, it is assumed that the dimensions of the sliding portion of the second guide portion 622 change due to deformation of the sliding portion of the second guide portion 622 caused by external forces on the pedal device 1 or by water absorption, expansion, and contraction of the second guide portion 622 due to the operating environment of the pedal device 1. In this case, the sliding portion between the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 may deform, as may the sliding portion between the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633. As a result, the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 may cease to slide along the vehicle's longitudinal direction Da, and the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 may cease to slide along the vehicle's longitudinal direction Da.

[0193] In contrast, in the 27th embodiment, the sliding portion between the first guide portion 614 and the second guide portion 622, projected in the vehicle's vertical direction Db, does not overlap with the sliding portion between the second guide portion 622 and the third guide portion 633, and is separated.

[0194] As a result, even if the sliding surface between the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 deforms due to the aforementioned forces, water absorption, expansion, and contraction, deformation of the sliding surface between the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 is suppressed. Furthermore, even if the sliding surface between the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 deforms due to the aforementioned forces, water absorption, expansion, and contraction, deformation of the sliding surface between the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 is suppressed. Therefore, even if one of the two sliding parts is fixed, sliding will still occur at the other sliding part. This prevents the pedal 10 from becoming unable to rotate when pressed.

[0195] (28th embodiment) In the 28th embodiment, as shown in Figure 36, the shapes of the second support portion 620, the third support portion 626, the first guide portion 614, the second guide portion 622, and the third guide portion 633 differ from those of the fifth embodiment. Other than these differences, it is the same as the fifth embodiment.

[0196] The second support portion 620 and the third support portion 626 are integrally formed and have a bottom portion and side portions. The bottom portions of the second support portion 620 and the third support portion 626 are formed in a plate shape extending in the vehicle's vertical direction Db. The side portions of the second support portion 620 and the third support portion 626 are formed in a cylindrical shape extending from the bottom portion in the rearward direction of the vehicle.

[0197] Here, assume that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected in the vehicle vertical direction Db toward the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. In this case, in the fifth embodiment, the sliding portion between the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db does not overlap with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Also, when the pedal portion 12 is not pressed by the driver, the sliding portion between the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db does not overlap with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Furthermore, even when the pedal portion 12 is pressed by the driver, the sliding portion between the first guide portion 614 and the second guide portion 622, projected in the vehicle's vertical direction Db, does not overlap with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Note that the sliding portions between the second support portion 620 and the third support portion 626 and the third guide portion 633 correspond to the contact portions between the second support portion 620 and the third support portion 626 and the third guide portion 633.

[0198] In contrast, in the 28th embodiment, the sliding portion between the first guide portion 614 and the second guide portion 622, projected in the vehicle's vertical direction Db, overlaps with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Furthermore, when the pedal portion 12 is not pressed by the driver, the sliding portion between the first guide portion 614 and the second guide portion 622, projected in the vehicle's vertical direction Db, overlaps with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Moreover, even when the pedal portion 12 is pressed by the driver, the sliding portion between the first guide portion 614 and the second guide portion 622, projected in the vehicle's vertical direction Db, overlaps with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633.

[0199] As described above, the pedal device 1 of the 28th embodiment is configured as described. This 28th embodiment also provides the same effects as the 5th embodiment. Furthermore, the 28th embodiment also provides the effects described below.

[0200] [4] Assume that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected in the vehicle vertical direction Db toward the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. At this time, the sliding portion between the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db overlaps with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633.

[0201] As a result, the size of the reaction force generating mechanism 60 in the vehicle's longitudinal direction Da becomes smaller compared to the case where the sliding portion between the projected first guide portion 614 and the second guide portion 622 does not overlap with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Therefore, an increase in the size of the pedal device 1 is suppressed.

[0202] (29th embodiment) In the 29th embodiment, as shown in Figure 37, the shapes of the first guide portion 614 and the second guide portion 622 differ from those of the 6th embodiment. Otherwise, it is the same as the 6th embodiment.

[0203] Here, let's assume that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected onto the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633 in the vehicle's vertical direction Db. In this case, the sliding portion between the first guide portion 614 and the second guide portion 622 projected onto the vehicle's vertical direction Db overlaps with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Furthermore, these sliding portions overlap when the pedal portion 12 is not being pressed by the driver, and when the pedal portion 12 is being pressed by the driver.

[0204] As described above, the pedal device 1 of the 29th embodiment is configured. This 29th embodiment also provides the same effects as the 6th embodiment. Furthermore, the 29th embodiment also provides the effects described in [4] above.

[0205] (30th embodiment) In the 30th embodiment, as shown in Figure 38, the shapes of the second support portion 620, the third support portion 626, the first guide portion 614, the second guide portion 622, and the third guide portion 633 differ from those of the 7th embodiment. Other than these differences, it is the same as the 7th embodiment.

[0206] The lengths of the second support portion 620 and the third support portion 626 in the vehicle longitudinal direction Da are longer compared to the seventh embodiment. Furthermore, suppose the sliding portion between the first guide portion 614 and the second guide portion 622 is projected in the vehicle vertical direction Db toward the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. In this case, the sliding portion between the first guide portion 614 and the second guide portion 622 projected toward the vehicle vertical direction Db does not overlap with the sliding portion between the second support portion 620 and the third support portion 626 and the third guide portion 633. Moreover, these sliding portions do not overlap when the pedal portion 12 is not being pressed by the driver, and when the pedal portion 12 is being pressed by the driver.

[0208] (31st Embodiment) In the 31st embodiment, as shown in Figure 39, the shapes of the first guide section 614, the second guide section 622, and the third guide section 633 differ from those of the 8th embodiment. Other than this, it is the same as the 8th embodiment.

[0209] The length of the first guide portion 614 in the vehicle longitudinal direction Da is shorter compared to the eighth embodiment. Furthermore, the length of the second guide portion 622 in the vehicle longitudinal direction Da is longer compared to the eighth embodiment. Also, suppose the sliding portion between the first guide portion 614 and the second guide portion 622 is projected into the vehicle vertical direction Db toward the sliding portion between the second guide portion 622 and the third guide portion 633. In this case, the sliding portion between the first guide portion 614 and the second guide portion 622 projected into the vehicle vertical direction Db does not overlap with the sliding portion between the second guide portion 622 and the third guide portion 633. Moreover, these sliding portions do not overlap when the pedal portion 12 is not being pressed by the driver, and when the pedal portion 12 is being pressed by the driver.

Other than this, it is the same as the 12th embodiment.

[0212] Instead of the fourth guide portion 654 extending forward from the boundary between the second support portion 620 and the third support portion 626, it extends rearward from the boundary between the second support portion 620 and the third support portion 626. Furthermore, suppose the sliding portion between the first guide portion 614 and the second guide portion 622 is projected in the vehicle's vertical direction Db toward the sliding portion between the fourth guide portion 654 and the third guide portion 633. In this case, the projected sliding portion between the first guide portion 614 and the second guide portion 622 in the vehicle's vertical direction Db overlaps with the sliding portion between the fourth guide portion 654 and the third guide portion 633. Also, when the pedal portion 12 is not pressed by the driver, and when the pedal portion 12 is pressed by the driver, the projected sliding portion between the first guide portion 614 and the second guide portion 622 overlaps with the sliding portion between the fourth guide portion 654 and the third guide portion 633.

[0215] Instead of the fourth guide portion 654 extending forward from the boundary between the second support portion 620 and the third support portion 626, it extends rearward from the boundary between the second support portion 620 and the third support portion 626. Also, instead of the outer surface of the third guide portion 633 and the inner surface of the fourth guide portion 654 sliding along the vehicle's longitudinal direction Da, the inner surface of the third guide portion 633 and the outer surface of the fourth guide portion 654 slide against each other. Furthermore, suppose the sliding portion between the first guide portion 614 and the second guide portion 622 is projected into the vehicle's vertical direction Db toward the sliding portion between the fourth guide portion 654 and the third guide portion 633.

[0230] The third support portion 626 is located further rearward than the second support portion 620 because it is connected to the part of the second guide portion 622 opposite to the second support portion 620. Furthermore, the third support portion 626 extends in the vertical direction Db of the vehicle from the part of the second guide portion 622 opposite to the second support portion 620 and is formed in an annular shape.

[0231] Instead of being supported by the guide member bottom 635, the second support portion 620, and the third support portion 626, the second elastic member 72 is supported by the housing cylindrical portion 44 and the third support portion 626.

Other than this, it is the same as the 26th embodiment.

[0234] Instead of extending forward in the vehicle direction from the boundary portion with the second support portion 620 and the third support portion 626, the fourth guide portion 654 extends rearward in the vehicle direction from the boundary portion with the second support portion 620 and the third support portion 626. Also, assume that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected in the vehicle vertical direction Db toward the sliding portion between the fourth guide portion 654 and the third guide portion 633. At this time, the sliding portion between the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db overlaps with the sliding portion between the fourth guide portion 654 and the third guide portion 633. Also, these sliding portions overlap both when the pedal portion 12 is not being stepped on by the driver and when the pedal portion 12 is being stepped on by the driver.

[0237] Specifically, instead of the second guide portion 622 being formed of metal, the second support portion 620, the third support portion 626, the second guide portion 622, and the fourth guide portion 654 of the second holder 62 are integrally formed of resin.

[0238] As described above, the pedal device 1 of the 40th embodiment is configured. Also in this 40th embodiment, the same effects as those of the 9th embodiment are achieved.

[0239] (Other embodiments) The present disclosure is not limited to the above embodiments, and appropriate changes can be made to the above embodiments. Also, in each of the above embodiments, the elements constituting the embodiment are not necessarily essential, except when explicitly stated as essential or when considered clearly essential in principle.

[0240] In each of the above embodiments, the pedal device 1 is used as a brake pedal for a brake-by-wire system 150 that controls the brakes of a vehicle. In contrast, the pedal device 1 is not limited to being used as a brake pedal. The pedal device 1 may be used, for example, as an accelerator pedal for accelerating the vehicle.

[0241] In each of the above embodiments, a reaction force is generated by the restoring force generated when the first elastic member 71, the second elastic member 72, and the third elastic member 73 are compressed, but it is not limited to this. For example, by changing the arrangement of the reaction force generating mechanism 60, a reaction force may be generated by the restoring force generated when the first elastic member 71, the second elastic member 72, and the third elastic member 73 are pulled. Also, the coil springs of the first elastic member 71, the second elastic member 72, and the third elastic member 73 are equally spaced coil springs, but it is not limited to this, and may be conical coil springs, unequally spaced coil springs, etc.

[0242] In each of the above embodiments, the pedal device 1 is a suspended type device, but it is not limited to this, and may be an organ type device. In the case of an organ type, a portion of the pedal 10 on the vehicle front side of the rotation axis O rotates toward the dash panel 200 in response to an increase in the driver's stepping force applied to the pedal 10.

[0243] In each of the above embodiments, the brake-by-wire system 150 generates hydraulic pressure in the brake fluid flowing through the brake circuit 120 by the master cylinder 126. However, the system is not limited to generating hydraulic pressure in the brake fluid flowing through the brake circuit 120 by the master cylinder 126. For example, hydraulic pressure may be generated in the brake fluid flowing through the brake circuit 120 by a hydraulic pump.

[0244] In the first embodiment described above, the third guide portion 633 is formed in a columnar shape. However, the third guide portion 633 may be formed in a cylindrical shape. In this case, the third guide portion 633 may slide against the holder cylindrical portion 624 or against the third support portion 626.
