[0007] Patent Document 1: Japanese Patent No. 6204658 Summary of the invention

[0008] According to the research of the inventors, in the pedal simulator described in Patent Document 1, when the brake pedal rotates, the piston moves along the cylinder body through the operating rod connected to the brake pedal, so that the spring is compressed. However, in the pedal simulator described in Patent Document 1, sometimes fine matter such as wear powder generated by the sliding of the piston and the cylinder body, and foreign matter invading from the outside of the cylinder body enter the sliding part between the piston and the cylinder body. At this time, the piston is fixed to the cylinder body, so that the piston can no longer move along the cylinder body, and therefore the brake pedal can no longer rotate.

[0009] An object of the present disclosure is to provide a pedal device which suppresses a pedal from being unable to rotate when the pedal is stepped on.

[0010] According to one aspect of the present disclosure, a pedal device is provided, comprising: a pedal that rotates around a rotation axis as a center by an operator's stepping on it; a first elastic member that is deformed by a force from the pedal when the pedal rotates, thereby generating a reaction force to the operator's stepping force; a second elastic member that is deformed by a force from the pedal when the pedal rotates, thereby generating a reaction force to the operator's stepping force; a first retainer that has a first support portion that is arranged on the pedal side and supports one end of the first elastic member, and a first guide portion that extends from the first support portion in a deformation direction of the first elastic member; and a second retainer that has a second support portion that supports the other end of the first elastic member, and a first guide portion that extends from the second support portion in a deformation direction of the first elastic member. An extending second guide portion, and a third support portion supporting one end of the second elastic component; a fourth support portion supporting the other end of the second elastic component; and a third guide portion extending from the fourth support portion toward the deformation direction of the second elastic component, wherein the first guide portion moves toward the deformation direction of the first elastic component and moves relative to the second guide portion due to the force from the pedal when the pedal rotates, thereby sliding with the second guide portion along the deformation direction of the first elastic component, thereby deforming the first elastic component, and the second retaining member moves toward the deformation direction of the second elastic component and moves relative to the third guide portion due to the force from the pedal when the pedal rotates, thereby sliding with the third guide portion along the deformation direction of the second elastic component, thereby deforming the second elastic component.

[0011] Thus, even if one of the two sliding parts is fixed, the other sliding part will slide. Therefore, it is possible to prevent the pedal from being unable to rotate when stepping on the pedal.

[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

[0061] 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 descriptions are omitted.

[0062] (First embodiment)

[0063] The pedal device 1 of the present embodiment is used as, for example, a brake pedal in a brake-by-wire system 150 that controls brakes of a vehicle. First, the brake-by-wire system 150 will be described.

[0064] Brake-by-wire system 150 Figure 1 As shown, wheel cylinders 131 to 134 , an ECU 110 , a brake circuit 120 , and a pedal device 1 are provided.

[0065] The wheel cylinders 131 to 134 are respectively arranged on the wheels of the vehicle. In addition, brake pads (not shown) are attached to the wheel cylinders 131 to 134 respectively.

[0066] 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. In addition, 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.

[0067] 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 along 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.

[0068] Here, in order to explain the following pedal device 1, the front-to-back direction of the vehicle is set as the vehicle front-to-back direction Da. The up-down direction (Japanese: sky-to-ground direction) of the vehicle is set as the vehicle up-to-down direction Db. The left-to-right direction of the vehicle is set as the vehicle left-to-right direction Dc. The front in the vehicle front-to-back direction Da is recorded as the vehicle front. The rear in the vehicle front-to-back direction Da is recorded as the vehicle rear. The top in the vehicle up-to-down direction Db is recorded as the vehicle top. The bottom in the vehicle up-to-down direction Db is recorded as the vehicle bottom. The left in the vehicle left-to-right direction Dc is recorded as the vehicle left. The right in the vehicle left-to-right direction Dc is recorded as the vehicle right.

[0069] The pedal device 1 is as follows Figure 2 to Figure 5 As shown, a pedal 10 , a stroke sensor 30 , a housing 40 , and a reaction force generating mechanism 60 are provided.

[0070] Pedal 10 Figure 2 as well as Figure 3 As shown, the driver of the vehicle is operated by stepping on the button. In addition, the driver of the vehicle corresponds to the operator.

[0071] Specifically, the pedal 10 includes a pedal portion 12, a rod portion 14, a rod protrusion 16, and a rod flange portion 18. The pedal portion 12 is stepped on by the driver. The rod portion 14 is connected to the pedal portion 12. In addition, when the pedal portion 12 is stepped on by the driver, the rod portion 14 rotates around the rotation axis O. The rod protrusion 16 is connected to the vehicle front side of the rod portion 14 and protrudes from the boundary portion with the rod portion 14 toward the front direction of the vehicle. The rod flange portion 18 is connected to the rod protrusion 16 and protrudes from the boundary portion with the rod protrusion 16 in a direction orthogonal to the protruding direction of the rod protrusion 16.

[0072] 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. Moreover, 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 detect 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.

[0073] The housing 40 is mounted on the dash panel 200 of the vehicle and is formed into a bottomed cylindrical shape so as to accommodate a part of the rod portion 14, the stroke sensor 30, and the reaction force generating mechanism 60 described later. The dash panel 200 is a partition that separates the outside of the vehicle compartment such as the engine compartment of the vehicle from the vehicle compartment, and is sometimes referred to as a transverse partition. In addition, outside the vehicle compartment, not only the vehicle engine but also, for example, the vehicle battery, air conditioning device, etc. are arranged.

[0074] Specifically, the housing 40 includes a housing bottom 42 , a housing tube 44 , a panel mounting portion 46 , panel bolts 48 , and a housing restricting portion 50 .

[0075] The housing bottom 42 extends in the vehicle front-rear direction Da. The rotation axis O of the rod 14 and the stroke sensor 30 are mounted on the housing bottom 42. The housing bottom 42 supports a part of the rod 14 so that the rod 14 can rotate around the rotation axis O and supports the stroke sensor 30.

[0076] The housing tube portion 44 corresponds to the fourth support portion, is connected to the end of the housing bottom portion 42 in the vehicle front-rear direction Da, and extends toward the vehicle lower direction from the boundary portion with the housing bottom portion 42. In addition, the housing tube portion 44 accommodates a portion of the rod portion 14, the stroke sensor 30, and a reaction force generating mechanism 60 described later.

[0077] The panel mounting portion 46 is connected to the end portion of the housing bottom 42 on the vehicle front side and the vehicle upper side, and extends from the boundary portion with the housing bottom 42 toward the vehicle upper direction. In addition, the panel mounting portion 46 is connected to the end portion of the housing tube portion 44 on the vehicle front side and the vehicle lower side, and extends from the boundary portion with the housing tube portion 44 toward the vehicle lower direction. Furthermore, a hole is formed in the panel mounting portion 46, and a panel bolt 48 is inserted into the hole of the panel mounting portion 46 and the hole of the dash panel 200, so that the housing 40 is mounted on the dash panel 200.

[0078] The housing restriction portion 50 is connected to the inner surface of the housing tube portion 44 located on the vehicle front side and protrudes from the inner surface toward the vehicle rear direction. In addition, a hole is formed in the housing restriction portion 50 for inserting a guide member 63 described later.

[0079] The reaction force generating mechanism 60 generates a reaction force to the pedal force of the driver applied to the pedal portion 12. Specifically, the reaction force generating mechanism 60 is as follows: Figure 4 As shown, the first holder 61 , the second holder 62 , the guide member 63 , the first elastic member 71 , the second elastic member 72 , and the third elastic member 73 are provided.

[0080] The first holder 61 is formed of, for example, resin. The first holder 61 includes a first support portion 610, a holder restriction portion 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 or the like.

[0081] 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 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. Figure 4 as well as Figure 5 As shown, it is formed in a cylindrical shape extending from the side of the first support portion 610 opposite to the holder restriction portion 612 toward the vehicle front direction.

[0082] The second holder 62 is formed of, for example, resin. The second holder 62 includes a second support portion 620, a second guide portion 622, a holder tube portion 624, and a third support portion 626. The second holder 62 is formed of resin, but is not limited thereto, and may be formed of, for example, metal or the like.

[0083] 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.

[0084] The second guide portion 622 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 into a cylindrical shape extending from the boundary portion with the second support portion 620 toward the vehicle rear direction. In addition, a portion of the second guide portion 622 is inserted into the hole of the first guide portion 614. Thus, the movement of the first guide portion 614 and the second guide portion 622 in the vehicle up-down direction Db is mutually restricted. Moreover, the first guide portion 614 and the second guide portion 622 extend along the vehicle front-rear direction Da, so that the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 slide along the vehicle front-rear direction Da.

[0085] The holder tube portion 624 is connected to the outer side of the second support portion 620 in a direction perpendicular to the vehicle front-rear direction Da, and extends from a boundary portion with the second support portion 620 toward the vehicle rear direction.

[0086] 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 holder tube portion 624 opposite to the second support portion 620, and is arranged on the vehicle rear side relative to the second support portion 620. In addition, a part of the first guide portion 614 is inserted into the hole of the third support portion 626.

[0087] The guide member 63 includes a third guide portion 633. The third guide portion 633 is formed of, for example, metal. In addition, the third guide portion 633 is formed in a cylindrical shape extending in the vehicle front-rear direction Da. Moreover, a portion of the third guide portion 633 is inserted into the hole of the outer shell cylinder portion 44 and the outer shell limiting portion 50. In addition, a portion 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 up-down direction Db is mutually restricted. In addition, the second guide portion 622 and the third guide portion 633 extend in the vehicle front-rear direction Da, so that the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 slide in the vehicle front-rear direction Da.

[0088] Here, the distance between the first retainer 61 and the second retainer 62 in the vehicle front-to-back direction Da, and the moving distance of the first retainer 61 from the pedal 10 being stepped on by the driver of the vehicle to the first retainer 61 and the second retainer 62 being in contact with each other is referred to as the first distance L1. 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 front-to-back direction Da. In addition, the distance between the second retainer 62 and the opposing portion that is opposed to the second retainer 62 in the moving direction in the vehicle front-to-back direction Da, and the moving distance of the second retainer 62 from the pedal 10 being stepped on by the driver of the vehicle to the second retainer 62 and the opposing portion being in contact with each other is referred to as the second distance L2. For example, here, the second distance L2 is the distance from the second retainer 62 to the housing restriction portion 50 in the vehicle front-to-back direction Da.

[0089] 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 along the vehicle front-rear direction Da. In addition, the first guide portion 614 and the second guide portion 622 are arranged inside the first elastic member 71. Thus, the movement of the first elastic member 71 in the vehicle up-down direction Db is restricted. Moreover, the first elastic member 71 is supported by the first support portion 610 and the second support portion 620 by contacting with the first support portion 610 and the second support 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, here, 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 becomes a free length.

[0090] 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 support portion 620 and the housing tube portion 44 by contacting the third support portion 626 and the housing tube portion 44. Moreover, the housing restriction portion 50 and the retainer tube portion 624 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 becomes a free length.

[0091] 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 in contact with the first support portion 610, and is supported by the first support portion 610. Moreover, a retainer restricting portion 612 is arranged 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 driver does not step on the pedal portion 12, a part of the rod convex portion 16 is inserted inside the third elastic member 73, so that the third elastic member 73 is in contact with the rod flange portion 18. At this time, the third elastic member 73 is elastically deformed, and is compressed here. In addition, here, when the driver does not step on the pedal portion 12, 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 becomes a free length. In addition, when the driver does not step on the pedal portion 12, the third elastic member 73 is in contact with the rod flange portion 18, but it is not limited to this. When the driver does not step on the pedal portion 12 , the third elastic member 73 and the lever flange portion 18 may be separated so as to be out of contact with each other.

[0092] The brake-by-wire system 150 is configured as described above. Next, the operation of the pedal device 1 will be described.

[0093] When the driver of the vehicle steps on the pedal portion 12, 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 that 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 in the vehicle front direction, so that the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 slide in the vehicle front direction, and the first elastic member 71 is pressed by the first support portion 610 and compressed. In addition, the force from the pedal portion 12 is transmitted to the second retainer 62. As a result, the second retainer 62 moves in the vehicle front direction, so that the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 slide in the vehicle front direction, and the second elastic member 72 is pressed by the third support portion 626 and compressed. Therefore, a reaction force is generated due to the restoring force generated by the compression of the first elastic member 71, the second elastic member 72, and the third elastic member 73. Through this reaction force, the pedal device 1 can obtain the same reaction force as when the pedal 10 is connected to the master cylinder 126, that is, when a reaction force based on hydraulic pressure is obtained, even if the mechanical connection between the pedal 10 and the master cylinder 126 is abolished.

[0094] 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.

[0095] At this time, the first ECU 111 supplies power to the motor 123, for example, to rotate 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.

[0096] 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 slows down. In addition, at this time, the second ECU 112 can also perform ABS control, VSC control, collision avoidance control, and regeneration cooperation control based on signals from the stroke sensor 30 and signals from other electronic control devices (not shown). In addition, ABS is the abbreviation of Anti-lock Braking System. And, VSC is the abbreviation of Vehicle Stability Control.

[0097] Here, for example, when the second holder 62 and the third guide portion 633 are fixed, when the first holder 61 moves the first distance L1, the absolute value of the deceleration amount of the vehicle becomes greater than the first threshold value, and the vehicle stops. In addition, when the first guide portion 614 and the second guide portion 622 are fixed, when the second holder 62 moves the second distance L2, the absolute value of the deceleration amount of the vehicle becomes greater than the second threshold value, and the vehicle stops. In addition, the first threshold value and the second threshold value are set by experiments, simulations, etc. in a manner that sufficiently obtains the deceleration amount of the vehicle.

[0098] Furthermore, when the driver of the vehicle 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 inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 slide in the rear direction of the vehicle, and the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 slide in the rear direction 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 driver of the vehicle does not step on the pedal portion 12.

[0099] The pedal device 1 operates in this manner. In the pedal device 1, it is possible to suppress the pedal 10 from becoming incapable of rotating when the pedal 10 is stepped on. Next, the suppression of the pedal 10 from becoming incapable of rotating will be described.

[0100] Here, the case where the pedal 10 cannot rotate is described using the first pedal device 901 for comparison and the second pedal device 902 for comparison. For this purpose, first, the first pedal device 901 for comparison is described. Figure 6 As shown, the comparison device includes a first guide portion 911 for comparison, a first support portion 921 for comparison, a second support portion 931 for comparison, a first elastic member 941 for comparison, a second elastic member 951 for comparison, and a pedal for comparison (not shown).

[0101] The first guide portion 911 for comparison is formed into a bottomed cylindrical shape, thereby accommodating the first support portion 921 for comparison, the second support portion 931 for comparison, the first elastic member 941 for comparison, and the second elastic member 951 for comparison, which will be described later. The first support portion 921 for comparison and the second support portion 931 for comparison are formed into a plate shape extending in a direction orthogonal to the left and right direction of the paper surface. In addition, the side surfaces extending in the left and right direction of the paper surface in the first support portion 921 for comparison and the second support portion 931 for comparison slide along the left and right direction of the paper surface with the inner surface of the first guide portion 911 for comparison. Moreover, the second support portion 931 for comparison is arranged on the left side of the paper surface than the first support portion 921 for comparison. The first elastic member 941 for comparison is arranged between the first support portion 921 for comparison and the second support portion 931 for comparison, and is supported by the first support portion 921 for comparison and the second support portion 931 for comparison. The second elastic member for comparison 951 is disposed between the second support portion for comparison 931 and the bottom of the first guide portion for comparison 911, and is supported by the second support portion for comparison 931 and the bottom of the first guide portion for comparison 911. The first elastic member for comparison 941 and the second elastic member for comparison 951 are elastically deformed in the horizontal direction of the paper.

[0102] Moreover, in the first comparison pedal device 901, for example, fine matter or foreign matter intruding from the outside enters between the first comparison support portion 921 and the first comparison guide portion 911 in the sliding portion. At this time, the first comparison support portion 921 and the first comparison guide portion 911 are fixed, and the first comparison support portion 921 can no longer move along the first comparison guide portion 911. Accompanying this, the first comparison elastic member 941 cannot be elastically deformed, so the force of the comparison pedal (not shown) is not transmitted to the second comparison support portion 931. Therefore, the second comparison support portion 931 cannot move along the first comparison guide portion 911. As a result, the comparison pedal (not shown) can no longer rotate. In addition, the reaction force generated by the first comparison elastic member 941 and the second comparison elastic member 951 is not transmitted to the comparison pedal (not shown). Here, the fine matter is, for example, abrasion powder or the like generated by sliding between the first comparative support portion 921 and the second comparative support portion 931 and the first comparative guide portion 911 .

[0103] Next, the second pedal device 902 for comparison will be described. Figure 7 As shown, it includes a third support portion for comparison 912, a fourth support portion for comparison 922, and a fifth support portion for comparison 932. In addition, the second pedal device for comparison 902 includes a first cylinder portion for comparison 942, a second cylinder portion for comparison 952, a second guide portion for comparison 962, a third elastic member for comparison 972, a fourth elastic member for comparison 982, and a pedal for comparison (not shown).

[0104] The third support part 912 for comparison, the fourth support part 922 for comparison, and the fifth support part 932 for comparison are formed into a plate shape extending in a direction orthogonal to the left-right direction of the paper. The fourth support part 922 for comparison is arranged on the left side of the paper surface than the third support part 912 for comparison. The fifth support part 932 for comparison is arranged on the left side of the paper surface than the fourth support part 922 for comparison. The first cylinder part 942 for comparison is connected to the third support part 912 for comparison, and extends from the boundary part with the third support part 912 to the left direction of the paper surface. The second cylinder part 952 for comparison is connected to the fourth support part 922 for comparison, and extends from the boundary part with the fourth support part 922 to the left direction of the paper surface. The second guide part 962 for comparison is connected to the fifth support part 932 for comparison, and is formed into a columnar shape extending from the fifth support part 932 for comparison to the right direction of the paper surface. In addition, a part of the second guide portion 962 for comparison is inserted into the hole of the first tube portion 942 for comparison and the hole of the second tube portion 952 for comparison. Moreover, the outer side surface of the second guide portion 962 for comparison extending in the left-right direction of the paper surface and the inner side surface of the first tube portion 942 for comparison extending in the left-right direction of the paper surface and the inner side surface of the first tube portion 942 for comparison extending in the left-right direction of the paper surface slide in the left-right direction of the paper surface. The third elastic member 972 for comparison is arranged between the third support portion 912 for comparison and the fourth support portion 922 for comparison, and is supported by the third support portion 912 for comparison and the fourth support portion 922 for comparison. The fourth elastic member 982 for comparison is arranged between the fourth support portion 922 for comparison and the fifth support portion 932 for comparison, and is supported by the fourth support portion 922 for comparison and the fifth support portion 932 for comparison. In addition, the third elastic member 972 for comparison and the fourth elastic member 982 for comparison are elastically deformed in the left-right direction of the paper surface.

[0105] Moreover, in the second comparison pedal device 902, for example, fine matter or foreign matter intruding from the outside enters between the first comparison cylinder 942 and the second comparison guide 962 in the sliding part. At this time, the first comparison cylinder 942 and the second comparison guide 962 are fixed, and the first comparison cylinder 942 can no longer move along the second comparison guide 962. With this, the third comparison elastic member 972 cannot be elastically deformed, so the force of the comparison pedal (not shown) is not transmitted to the fourth comparison support 922 and the second comparison cylinder 952. Therefore, the second comparison cylinder 952 cannot move along the second comparison guide 962. As a result, the comparison pedal (not shown) cannot rotate. In addition, the reaction force generated by the third comparison elastic member 972 and the fourth comparison elastic member 982 is not transmitted to the comparison pedal (not shown). Here, the fine matter is, for example, abrasion powder or the like generated by sliding between the first comparative cylinder 942 and the second comparative cylinder 952 and the second comparative guide 962 .

[0106] In contrast, in the pedal device 1 of the present embodiment, the first guide portion 614 and the second guide portion 622 slide in the vehicle front-rear direction Da by the force from the pedal 10 when the pedal 10 rotates, so that the first elastic member 71 is deformed. In addition, the second guide portion 622 and the third guide portion 633 of the second holder 62 slide in the vehicle front-rear direction Da by the force from the pedal 10 when the pedal 10 rotates, so that the second elastic member 72 is deformed. In addition, the vehicle front-rear direction Da corresponds to the deformation direction of the first elastic member 71 and the deformation direction of the second elastic member 72.

[0107] Thus, when the second retainer 62 and the third guide portion 633 are fixed, the first guide portion 614 and the second guide portion 622 slide in the vehicle front-rear direction Da by the force from the pedal 10 when the pedal 10 rotates. In addition, when the first guide portion 614 and the second guide portion 622 are fixed, the second guide portion 622 and the third guide portion 633 of the second retainer 62 slide in the vehicle front-rear direction Da by the force from the pedal 10 when the pedal 10 rotates. Therefore, even if one of the two sliding portions is fixed, the other sliding portion slides. Therefore, it is possible to suppress the situation where the pedal 10 cannot rotate when the pedal 10 is stepped on.

[0108] In addition, in the first embodiment, the following effects are also achieved.

[0109] [1-1] The first guide portion 614 is formed in a cylindrical shape. The second guide portion 622 is formed in a cylindrical shape. Thus, when the first guide portion 614 and the second guide portion 622 are assembled, even if the first guide portion 614 and the second guide portion 622 are rotated around the axis, the shapes of the first guide portion 614 and the second guide portion 622 can easily correspond to each other. Therefore, when the first guide portion 614 and the second guide portion 622 are assembled, the first guide portion 614 and the second guide portion 622 can be assembled without considering the rotation direction of the first guide portion 614 and the second guide portion 622 around the axis. Therefore, the assembly of the first guide portion 614 and the second guide portion 622 becomes easy.

[0110] In addition, the third guide portion 633 is formed in a cylindrical shape. Thus, when the second guide portion 622 and the third guide portion 633 are assembled, even if the second guide portion 622 and the third guide portion 633 are rotated around the axis, the shapes of each other are easily matched. Therefore, when the second guide portion 622 and the third guide portion 633 are assembled, the second guide portion 622 and the third guide portion 633 can be assembled without considering the rotation direction of the second guide portion 622 and the third guide portion 633 around the axis. Therefore, the assembly of the second guide portion 622 and the third guide portion 633 becomes easy.

[0111] [1-2] The deformation direction of the first elastic member 71, the deformation direction of the second elastic member 72, and the deformation direction of the third elastic member 73 are the linear directions orthogonal to the rotation axis O, which are the vehicle front-rear direction Da in this case. As a result, the first elastic member 71, the second elastic member 72, and the third elastic member 73 are not inclined but are easily compressed, so a stable reaction force is generated.

[0112] [1-3] When the second elastic member 72 is projected in the vehicle vertical direction Db, the projected second elastic member 72 overlaps the first elastic member 71. The vehicle vertical direction Db corresponds to a direction orthogonal to the deformation direction of the second elastic member 72.

[0113] Thus, the volume of the reaction force generating mechanism 60 in the vehicle longitudinal direction Da is reduced compared to a case where the second elastic member 72 and the first elastic member 71 projected in the vehicle vertical direction Db do not overlap. Therefore, the volume of the pedal device 1 can be suppressed from increasing.

[0114] [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 arranged inside the first elastic member 71. As a result, the volume of the first retainer 61 and the second retainer 62 in the vehicle up-down direction Db is reduced compared to the case where the first guide portion 614 and the second guide portion 622 are arranged outside the first elastic member 71. As a result, the volume of the pedal device 1 can be suppressed from being enlarged. In addition, the first guide portion 614 and the second guide portion 622 are surrounded by the first elastic member 71, so it is difficult for foreign matter from the outside to invade the sliding portion of the first guide portion 614 and the second guide portion 622.

[0115] [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 arranged inside the second elastic member 72. Therefore, compared with the case where the second guide portion 622 and the third guide portion 633 are arranged outside the second elastic member 72, the volume of the second retainer 62 in the vehicle vertical direction Db becomes smaller. Thus, the increase in the volume of the pedal device 1 can be suppressed. In addition, the second guide portion 622 and the third guide portion 633 are surrounded by the second elastic member 72, so it is difficult for foreign matter from the outside to invade the sliding parts of the second guide portion 622 and the third guide portion 633.

[0116] [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 difficult to move in the vehicle vertical direction Db, and therefore, friction between the first support portion 610 and the second support portion 620 supporting the first elastic member 71 is difficult to generate. Therefore, the amount of wear of the first elastic member 71, the first support portion 610, and the second support portion 620 is reduced. In addition, the first elastic member 71 is difficult to move in the vehicle vertical direction Db, so the first elastic member 71 is not tilted and is easily compressed, thereby generating a stable reaction force. In addition, the first guide portion 614 and the second guide portion 622 correspond to the restriction portion.

[0117] [1-7] The retainer tube 624 and the housing limiting portion 50 limit the movement of the second elastic member 72 in the vehicle vertical direction Db. As a result, the second elastic member 72 is difficult to move in the vehicle vertical direction Db, and therefore, it is difficult to generate friction between the third support portion 626 and the housing tube 44 that support the second elastic member 72. Therefore, the amount of wear of the second elastic member 72, the third support portion 626, and the housing tube 44 is reduced. In addition, the second elastic member 72 is difficult to move in the vehicle vertical direction Db, so the second elastic member 72 is not tilted and is easily compressed, so a stable reaction force will be generated. In addition, the retainer tube 624 and the housing limiting portion 50 correspond to the limiting portion.

[0118] [1-8] The third guide portion 633 includes metal. Thus, since metal is a relatively hard-to-deform material, it is possible to suppress the third guide portion 633 from being damaged and no longer sliding with the second guide portion 622. In addition, the housing 40 includes resin. Therefore, when the housing 40 connected to the third guide portion 633 is formed, it is possible to integrally mold the housing 40 by, for example, injection molding. Furthermore, the second guide portion 622 includes resin. Thus, compared with the case where the second guide portion 622 and the third guide portion 633 are made of metal, the friction coefficient between the second guide portion 622 and the third guide portion 633 is reduced. Therefore, the friction force between the second guide portion 622 and the third guide portion 633 is reduced, and thus the generation of sound accompanying the friction between the second guide portion 622 and the third guide portion 633 can be suppressed. In addition, since the specific gravity of the resin is relatively small, the weight of the second guide portion 622 is suppressed, and the second guide portion 622 can be made lightweight. Therefore, the weight of the pedal device 1 is suppressed, and the pedal device 1 can be made lightweight.

[0119] [1-9] The first elastic member 71, the second elastic member 72, and the third elastic member 73 are coil springs. Therefore, the influence of temperature on the elastic coefficients 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 difficult to deteriorate, and thus a stable reaction force is generated.

[0120] [1-10] The pedal 10 is a brake pedal used in a vehicle. In the pedal device 1 of the present embodiment, it is possible to suppress a situation where the pedal 10 cannot rotate when the pedal 10 is stepped on, and thus it is possible to suppress a situation where the vehicle cannot be braked.

[0121] [1-11] The first guide portion 614 and the second support portion 620 are opposed to each other in the vehicle front-rear direction Da, and are moved toward the second support portion 620 by the force from the pedal 10 when the pedal 10 rotates. The second support portion 620 and the third support portion 626 are opposed to the outer shell tube portion 44 in the vehicle front-rear direction Da, and are moved toward the outer shell tube portion 44 by the force from the pedal 10 when the pedal 10 rotates. In addition, when the first retaining member 61 moves the first distance L1, the absolute value of the deceleration amount of the vehicle becomes greater than the threshold value, and the vehicle stops. In addition, when the second retaining member 62 moves the second distance L2, the absolute value of the deceleration amount of the vehicle becomes greater than the threshold value, and the vehicle stops. In addition, as described above, the first threshold value and the second threshold value are set through experiments, simulations, etc. in a manner that fully obtains the deceleration amount of the vehicle.

[0122] Thus, even if one of the two sliding portions is fixed, the pedal 10 rotates so that the vehicle can be sufficiently decelerated. Therefore, it is possible to suppress a situation where the vehicle cannot be braked.

[0123] [1-12] The housing 40 that houses the reaction force generating mechanism 60 is disposed on the vehicle compartment side of the dash panel 200 that separates the vehicle compartment from the outside of the vehicle compartment. As a result, moisture and oil from the engine compartment are difficult to enter the vehicle compartment, so moisture and oil from the engine compartment are difficult to adhere to the first elastic member 71, the second elastic member 72, and the 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 difficult to enter the vehicle compartment. Therefore, the first elastic member 71, the second elastic member 72, and the third elastic member 73 are difficult to deteriorate, so the durability is improved.

[0124] [1-13] The first guide portion 614 and the second guide portion 622 restrict each other's movement in the vehicle up-down direction Db. The vehicle up-down direction Db corresponds to a direction orthogonal to the deformation direction of the first elastic member 71 .

[0125] Thus, the first guide portion 614 and the second guide portion 622 are prevented from entering the inner side of the first elastic member 71, thereby preventing the elastic deformation of the first elastic member 71 from being hindered. In addition, the first guide portion 614 and the second guide portion 622 are prevented from biting into the first elastic member 71, thereby preventing the first elastic member 71 from being damaged. Therefore, the restoring force of the first elastic member 71 is prevented from being transmitted to the pedal 10, thereby preventing the pedal 10 from returning to its original position.

[0126] The second holder 62 and the third guide portion 633 restrict each other from moving in the vehicle up-down direction Db. The vehicle up-down direction Db corresponds to a direction perpendicular to the deformation direction of the second elastic member 72 .

[0127] Thus, the second holder 62 and the third guide portion 633 are prevented from entering the inner side of the second elastic member 72, thereby preventing the elastic deformation of the second elastic member 72 from being hindered. Furthermore, the second holder 62 and the third guide portion 633 are prevented from biting into the second elastic member 72, thereby preventing the second elastic member 72 from being damaged. Therefore, the restoring force of the second elastic member 72 is prevented from being transmitted to the pedal 10, thereby preventing the pedal 10 from returning to its original position.

[0128] [1-14] The first elastic member 71, the second elastic member 72, and the third elastic member 73 are elastically deformed, and are compressed here, when the driver of the vehicle is not stepping on the pedal 10. Therefore, even if the first elastic member 71, the second elastic member 72, and the third elastic member 73 are damaged when they are elastically deformed by the driver of the vehicle stepping on the pedal 10, the position of the pedal 10 can be easily returned to its original position by the restoring force generated by returning to their respective free lengths.

[0129] (Second embodiment)

[0130] In the second embodiment, Figure 8 As shown, the pedal 10 is different from the first embodiment. In addition, the second holder 62 is different from the first embodiment. Moreover, the guide member 63 is different from the first embodiment. Moreover, the housing 40 does not have the housing restriction portion 50. Other than that, it is the same as the first embodiment.

[0131] The pedal 10 has a rod plate portion 20 instead of the rod convex portion 16 and the rod flange portion 18. The rod plate portion 20 is formed in a plate shape and is connected to the vehicle front side of the rod portion 14. In addition, the rod plate portion 20 contacts 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 driver does not step on the pedal portion 12, the length of the third elastic member 73 becomes a free length. In addition, here, when the driver does not step on the pedal portion 12, the third elastic member 73 is not elastically deformed, but it is not limited to this, and elastic deformation is also possible. In addition, when the driver does not step on the pedal portion 12, the third elastic member 73 contacts the rod plate portion 20, but it is not limited to this. It is also possible that when the driver does not step on the pedal portion 12, the third elastic member 73 is separated from the rod plate portion 20, so that the third elastic member 73 and the rod plate portion 20 are non-contact.

[0132] The second holder 62 does not include the holder tube portion 624. In addition, the second support portion 620 and the third support portion 626 of the second holder 62 are integrated.

[0133] 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. Moreover, the guide member bottom 635 is connected to the third guide portion 633. In addition, the guide member bottom 635 is connected to the inner surface of the outer shell tube portion 44 located on the front side of the vehicle. Moreover, the guide member bottom 635 contacts the side of the second elastic member 72 opposite to the third support portion 626, thereby supporting the second elastic member 72.

[0134] The pedal device 1 of the second embodiment is configured as described above. In the second embodiment as well, the same effects as those of the first embodiment are achieved.

[0135] (Third embodiment)

[0136] In the third embodiment, Fig. 9 As shown in FIG. 1 , the second holder 62 and the third guide portion 633 are different from those in the second embodiment. Other than that, the second embodiment is the same as the second embodiment.

[0137] The second retainer 62 includes a second support portion 620, a third support portion 626, and a second guide portion 622. The second support portion 620 and the third support portion 626 are integrated and formed into a plate shape extending in the vehicle vertical direction Db. The second guide portion 622 is formed of, for example, metal. In addition, the second guide portion 622 is connected to the second support portion 620 and is formed into a cylindrical shape extending from the boundary portion with the second support portion 620 toward the rear direction of the vehicle. In addition, a portion of the second guide portion 622 is inserted into the hole of the first guide portion 614. Thus, the movement of the first guide portion 614 and the second guide portion 622 in the vehicle vertical direction Db is mutually restricted. Moreover, the first guide portion 614 and the second guide portion 622 extend in the vehicle front-rear direction Da, so that the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 slide in the vehicle front-rear direction Da.

[0138] The third guide portion 633 is formed of resin instead of metal. In addition, the third guide portion 633 is formed into a cylindrical shape extending in the vehicle front-rear direction Da instead of a cylindrical shape. Thus, the guide member 63 is formed into a bottomed cylindrical shape. In addition, the second support portion 620 and the third support portion 626 are inserted into the hole of the third guide portion 633. Thus, the movement of the second support portion 620, the third support portion 626 and the third guide portion 633 in the vehicle up-down direction Db is restricted. In addition, the third guide portion 633 extends in the vehicle front-rear direction Da, so that the side surfaces of the second support portion 620 and the third support portion 626 extending in the vehicle front-rear direction Da and the inner surface of the third guide portion 633 slide in the vehicle front-rear direction Da.

[0139] The pedal device 1 of the third embodiment is configured as described above. In the third embodiment as well, the same effects as those of the second embodiment are achieved.

[0140] (Fourth embodiment)

[0141] In the fourth embodiment, Fig.10 As shown in the figure, the form of the pedal 10 is different 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, the second holder 62, the guide member 63, the first elastic member 71, the second elastic member 72 and the third elastic member 73. Moreover, the form of the first holder 61 is different from that of the first embodiment. Other than this, it is the same as the third embodiment.

[0142] The pedal 10 includes a lever protrusion 16 instead of the lever plate portion 20. The lever protrusion 16 is connected to the vehicle front side of the lever portion 14 and protrudes from the boundary portion with the lever portion 14 toward the vehicle front direction.

[0143] The third holder 65 is formed of, for example, resin. In addition, the third holder 65 includes a holder support portion 650 and a fourth guide portion 654 .

[0144] The holder support portion 650 is, for example, formed in a plate shape extending in a direction perpendicular to the vehicle front-rear direction Da. In addition, the holder support portion 650 is in contact with the rod convex portion 16. In addition, when the driver does not step on the pedal portion 12, the holder support portion 650 is in contact with the rod convex portion 16, but it is not limited to this. Alternatively, when the driver does not step on the pedal portion 12, the holder support portion 650 is separated from the rod convex portion 16, so that the holder support portion 650 and the rod convex portion 16 are non-contacting.

[0145] The fourth guide portion 654 is formed, for example, in a cylindrical shape extending toward the vehicle front direction from the end surface of the holder support portion 650 on the side opposite to the lever protrusion 16. The fourth guide portion 654 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.

[0146] The first retainer 61 has a fifth guide portion 615 instead of the retainer restriction portion 612. The fifth guide portion 615 is formed of, for example, metal. In addition, the fifth guide portion 615 is connected to the first support portion 610 and is formed in a cylindrical shape extending from the boundary portion with the first support portion 610 to the rear direction of the vehicle. In addition, a portion of the fifth guide portion 615 is inserted into the hole of 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 up-down direction Db is mutually restricted. Moreover, the fourth guide portion 654 and the fifth guide portion 615 extend in the vehicle front-back direction Da, so that the inner surface of the fourth guide portion 654 and the outer surface of the fifth guide portion 615 slide in the vehicle front-back direction Da.

[0147] The pedal device 1 of the fourth embodiment is configured as described above. In the fourth embodiment as well, the same effects as those of the third embodiment are achieved.

[0148] (Fifth embodiment)

[0149] In the fifth embodiment, Fig.11 As shown, the pedal 10 is different from the third embodiment in form.

Furthermore, the first guide portion 614 and the second guide portion 622 extend in the vehicle front-rear direction Da, so that the outer surface of the first guide portion 614 and the inner surface of the second guide portion 622 slide in the vehicle front-rear direction Da.

[0264] The pedal device 1 of the 26th embodiment is configured as described above. In the 26th embodiment as well, the same effects as those of the 24th embodiment are achieved.

[0265] (Implementation 27)

[0266] In the 27th embodiment, Fig.35 As shown in FIG. 1 , the configurations of the first guide portion 614 , the second guide portion 622 , and the third guide portion 633 are different from those of the first embodiment. Other configurations are the same as those of the first embodiment.

[0267] Here, it is assumed that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected toward the sliding portion between the second guide portion 622 and the third guide portion 633 in the vehicle vertical direction Db. At this time, in the first embodiment, 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 guide portion 622 and the third guide portion 633. In addition, when the pedal portion 12 is not stepped on by the driver and when the pedal portion 12 is stepped on by the driver, the above-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. In addition, 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. In addition, 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 .

[0268] On the other hand, in the 27th embodiment, the sliding portion of the first guide portion 614 and the second guide portion 622 projected in the vehicle up-down direction Db does not overlap with the sliding portion of the second guide portion 622 and the third guide portion 633. In addition, when the pedal portion 12 is not stepped on by the driver and when the pedal portion 12 is stepped on by the driver, the sliding portion of the first guide portion 614 and the second guide portion 622 projected does not overlap with the sliding portion of the second guide portion 622 and the third guide portion 633.

[0269] The pedal device 1 of the 27th embodiment is configured as described above. In the 27th embodiment, the same effects as those of the first embodiment are achieved. In the 27th embodiment, the following effects are also achieved.

[0270] [3] In addition, it is assumed here that the sliding portion between the first guide portion 614 and the second guide portion 622 and the sliding portion between the second guide portion 622 and the third guide portion 633 projected in the vehicle vertical direction Db overlap. In addition, at this time, it is assumed that the sliding portion of the second guide portion 622 is deformed due to the force from the outside of the pedal device 1, the absorption of water, expansion and contraction of the second guide portion 622 caused by the use environment of the pedal device 1, etc., so that the size of the sliding portion of the second guide portion 622 changes. 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 be deformed, and the sliding portion between the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 may be deformed. Therefore, the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 may no longer slide in the vehicle front-rear direction Da, and the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 may no longer slide in the vehicle front-rear direction Da.

[0271] On the other hand, in the 27th embodiment, the sliding portion between the first guide portion 614 and the second guide portion 622 and the sliding portion between the second guide portion 622 and the third guide portion 633 projected in the vehicle up-down direction Db do not overlap but are separated.

[0272] Thus, even if the sliding portion between the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 is deformed due to the above-mentioned force, water absorption, expansion, contraction, etc., the deformation of the sliding portion between the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 can be suppressed. In addition, even if the sliding portion between the inner surface of the second guide portion 622 and the outer surface of the third guide portion 633 is deformed due to the above-mentioned force, water absorption, expansion, contraction, etc., the deformation of the sliding portion between the inner surface of the first guide portion 614 and the outer surface of the second guide portion 622 can be suppressed. Therefore, even if one of the two sliding portions is fixed, the sliding portion of the other slides. Therefore, the pedal 10 can be suppressed from being unable to rotate when the pedal 10 is stepped on.

[0273] (Implementation 28)

[0274] In the 28th embodiment, Fig.36 As shown in FIG. 1 , the second supporting portion 620 , the third supporting portion 626 , the first guiding portion 614 , the second guiding portion 622 , and the third guiding portion 633 are different from those in the fifth embodiment. Other than that, the fifth embodiment is the same as the fifth embodiment.

[0275] The second support portion 620 and the third support portion 626 are integrated and have a bottom and a side. The bottom of the second support portion 620 and the third support portion 626 is formed in a plate shape extending in the vehicle up-down direction Db. The side of the second support portion 620 and the third support portion 626 is formed in a cylindrical shape extending from the bottom toward the rear of the vehicle.

[0276] Here, it is assumed that the sliding portion of the first guide portion 614 and the second guide portion 622 is projected toward the second support portion 620 and the sliding portion of the third support portion 626 and the third guide portion 633 in the vehicle vertical direction Db. At this time, in the fifth embodiment, the sliding portion of 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 of the second support portion 620 and the third support portion 626 and the third guide portion 633. In addition, when the pedal portion 12 is not stepped on by the driver, the sliding portion of 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 of the second support portion 620 and the third support portion 626 and the third guide portion 633. Furthermore, when the pedal portion 12 is stepped on by the driver, the sliding portion of 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 of the second support portion 620 and the third support portion 626 and the third guide portion 633. In addition, the sliding portion of the second support portion 620 and the third support portion 626 and the third guide portion 633 corresponds to the contact portion of the second support portion 620 and the third support portion 626 and the third guide portion 633.

[0277] On the other hand, in the 28th embodiment, the sliding portion of the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db overlaps with the sliding portion of the second support portion 620 and the third support portion 626 and the third guide portion 633. In addition, when the pedal portion 12 is not stepped on by the driver, the sliding portion of the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db overlaps with the sliding portion of the second support portion 620 and the third support portion 626 and the third guide portion 633. Moreover, when the pedal portion 12 is stepped on by the driver, the sliding portion of the first guide portion 614 and the second guide portion 622 projected in the vehicle vertical direction Db overlaps with the sliding portion of the second support portion 620 and the third support portion 626 and the third guide portion 633.

[0278] The pedal device 1 of the 28th embodiment is configured as described above. In the 28th embodiment, the same effects as those of the 5th embodiment are achieved. In addition, the 28th embodiment also achieves the effects described below.

[0279] [4] Assume that the sliding portion between the first guide portion 614 and the second guide portion 622 is projected toward the second support portion 620 and the sliding portion between the third support portion 626 and the third guide portion 633 in the vehicle vertical direction Db. At this time, the sliding portion between the first guide portion 614 and the second guide portion 622 projected toward 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.

[0280] As a result, the volume of the reaction force generating mechanism 60 in the vehicle front-rear direction Da is reduced compared to the case where the sliding portion of the projected first guide portion 614 and the second guide portion 622 does not overlap with the sliding portion of the second support portion 620 and the third support portion 626 and the third guide portion 633. Therefore, the volume of the pedal device 1 can be suppressed from being enlarged.

[0281] (Implementation No. 29)
