Pedal device

Abstract

A pedal pad (30) is subjected to a depression operation from a prescribed operation side by a driver (81). An arm (40) has an arm one end portion (401) and an arm main body portion (403) extending from the arm one end portion toward a counter operation side. The arm is linked at the arm one end portion to the pedal pad and at the counter operation side to a reaction force generating mechanism (50) which generates a reaction force with respect to a depression force applied to the pedal pad by the driver. An anti-extraction member (56) is configured as a separate member from the pedal pad and is fixed to the pedal pad. One of the pedal pad and the anti-extraction member, i.e., one member has a first arrangement portion (564), and the other of them, i.e., the other member has a second arrangement portion (306) arranged on the operation side across the arm one end portion from the first arrangement portion. Further, the first arrangement portion and the second arrangement portion hold the arm one end portion to the pedal pad in a state in which the arm one end portion is interposed between the first arrangement portion and the second arrangement portion.

[0002] This application is based on Japanese Patent Application No. 2021-29093, filed on February 25, 2021, the contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to pedal devices installed in vehicles. Background Technology

[0004] As such a pedal device, a pedal device described in, for example, Patent Document 1 is currently known. The pedal device described in Patent Document 1 includes a pedal housing, a pedal pad rotatably connected to the pedal housing, and a connecting rod. The connecting rod has a connector and a connecting body.

[0005] The connector of the connecting rod is rotatably embedded in a connecting recess located on the back of the pedal on the opposite side (the side operated by the driver), i.e., the reverse operating side. Furthermore, the connecting body of the connecting rod extends from the connector towards the reverse operating side and inserts into the pedal housing.

[0008] Patent Document 1: Chinese Utility Model Announcement No. 201511825 Specification Summary of the Invention

[0009] In the pedal device of Patent Document 1, the connecting head of the connecting rod is rotatably engaged with the connecting recess of the pedal pad, but when they are engaged, the connecting head is embedded in the connecting recess by causing elastic deformation of the connecting recess and its surrounding portion in the pedal pad.

[0010] Therefore, it is difficult to set the overlap width between the connecting recess of the pedal pad and the connector of the connecting rod to be sufficiently large to maintain the connection between the connecting recess and the connector. As a result, it is conceivable that, for example, if an external force is accidentally applied to the pedal pad, the connection between the connecting recess and the connector may easily detach. That is, it is considered difficult to connect the connecting rod to the pedal pad with sufficient strength. The inventors conducted a detailed investigation and discovered the above situation.

[0011] In view of the above points, the object of this disclosure is to provide a pedal device capable of connecting the connecting rod to the pedal pad with sufficient strength.

[0012] To achieve the above objectives, according to one aspect of this disclosure, the pedal device is a pedal device provided in a vehicle, wherein it comprises:

[0013] A pedal pad, which is stepped on by the driver from a designated operating side;

[0014] An arm having an arm end and an arm body extending from the arm end toward a side opposite to the operating side, i.e., a counter-operation side, the arm being connected at the arm end to a pedal pad and, on the counter-operation side, to a reaction force generating mechanism that generates a reaction force relative to the driving force applied to the pedal pad; and

[0015] An anti-detachment component, wherein the anti-detachment component is configured as a separate part from the pedal pad and is fixed to the pedal pad;

[0016] One end of the arm is formed into a shape that widens from the main body of the arm in a widening direction perpendicular to the extension direction of the main body of the arm.

[0017] One of the pedal pad and the anti-slip component has a first mounting portion, which has an insertion hole through which the arm body portion is inserted, and is positioned on the reverse operation side relative to one end of the arm.

[0018] The other component, either the pedal pad or the anti-slip part, has a second configuration portion, which is located on the operating side of the arm, separated from the first configuration portion by one end.

[0019] The first configuration section and the second configuration section hold one end of the arm in a state where the arm is sandwiched between the first configuration section and the second configuration section, thus holding one end of the arm in the pedal pad.

[0020] Therefore, since the first and second configuration parts are different components, it is possible to ensure that the first configuration part can withstand the external force and bear the width of the arm end when an external force is applied to one end of the arm in the direction of pressing the first configuration part. Thus, compared with the structure of the pedal device in Patent Document 1, for example, the arm, which is equivalent to the connecting rod described above, can be connected to the pedal pad with sufficient strength.

[0021] Furthermore, the parenthesized reference marks used to annotate each constituent element, etc., indicate an example of the correspondence between that constituent element, etc., and the specific constituent elements, etc., described in the embodiments described later.

[0062] Hereinafter, each embodiment will be described with reference to the accompanying drawings. Furthermore, in each of the following embodiments, the same or equivalent parts are labeled with the same reference numerals in the drawings.

[0063] <First Implementation Method>

[0064] like Figure 1 As shown, the pedal device 1 in this embodiment is a device mounted on the vehicle 80, and is operated by the pedal force of the occupant of the vehicle 80, i.e., the driver 81. This pedal device 1 is provided in the vehicle 80 as a brake pedal device for performing braking operations to brake the vehicle 80.

[0065] In detail, Figure 1The vehicle 80 employs a brake-by-wire system, and the pedal device 1 is a brake pedal device used in this brake-by-wire system. A brake-by-wire system refers to a system that, based on an electrical signal output from the pedal device 1, drives the brake pads of each wheel via a brake circuit using hydraulic pressure generated by the master cylinder under the drive control of an electronic control unit mounted on the vehicle 80.

[0066] also, Figure 1 The double-headed arrows indicate the directions of the vehicle 80 equipped with the pedal device 1. That is, in Figure 1 In this embodiment, the forward and backward direction of vehicle 80 (i.e., the forward and backward direction Da) and the vertical direction of vehicle 80 (in other words, the height direction of vehicle 80) (i.e., the vertical direction Db) are represented by double-headed arrows. Furthermore, in this description, the front of vehicle in the forward and backward direction Da is also referred to as the front of the vehicle, the rear of vehicle in the forward and backward direction Da is also referred to as the rear of the vehicle, the upper part of vehicle in the vertical direction Db is also referred to as the upper part of the vehicle, and the lower part of vehicle in the vertical direction Db is also referred to as the lower part of the vehicle.

[0067] like Figure 2 and Figure 3 As shown, the pedal device 1 is an accordion-type pedal device. The pedal device 1 includes a housing 10, a shaft 20, a pedal pad 30, an arm 40, a reaction force generating mechanism 50, an anti-slip part 56, and a rotation angle sensor (not shown). An accordion-type pedal device 1 refers to a pedal device in which the portion of the pedal pad 30 that is stepped on by the driver 81 is positioned above the vehicle (in other words, above in the height direction when mounted on the vehicle) relative to the rotation center CL of the pedal pad 30. Furthermore, in the accordion-type pedal device 1, the portion of the pedal pad 30 that is above the vehicle above the rotation center CL rotates towards the floor 2 side or the front panel side of the vehicle interior as the driving force applied to the pedal pad 30 increases. In this embodiment, the rotation center CL of the pedal pad 30 is also referred to as the pedal axis CL.

[0068] like Figure 3 As shown, the outer casing 10 is mounted on a part of the body constituting the vehicle 80. Specifically, the outer casing 10 is mounted to the floor 2 or front bulkhead, etc., inside the vehicle 80 by screws 3. Furthermore, the front bulkhead is a partition wall separating the exterior of the vehicle 80's engine compartment and other interior spaces from the interior space; it is sometimes referred to as a transverse partition. Additionally, in Figure 2 and Figure 3 In the diagram, the pedal device 1 is shown in its non-pedaling state when the driver 81 is not pressing the pedal pad 30.

[0069] like Figure 2 and Figure 3As shown, the outer casing 10 has an outer casing body 11 and an outer casing cover 12. The outer casing 10 is disposed between the pedal pad 30 when the driver 81 is in the deepest depressed state and the floor 2, which is part of the vehicle body. Inside the outer casing body 11, a space is formed for housing a reaction force generating mechanism 50, etc. In addition, the outer casing body 11 has a bearing portion 111 for supporting the shaft 20 so that it can rotate. On the other hand, the outer casing cover 12 is disposed on the side of the outer casing body 11 and closes the side opening of the space formed inside the outer casing body 11.

[0070] The shaft 20 is, for example, designed to be a cylindrical metal that has been bent multiple times, and has a shaft portion 21, a fixing portion 22, and a connecting portion 23. That is, the shaft portion 21, the connecting portion 23, and the fixing portion 22 are configured as a single part and are connected in series in the order of shaft portion 21, connecting portion 23, and fixing portion 22.

[0071] Shaft 20 is a rotating shaft component having a shaft portion 21 that serves as the rotating shaft of the pedal pad 30. The shaft portion 21 is formed into a cylindrical shaft shape centered on the pedal shaft center CL and is inserted into a shaft hole 13a formed inside the bearing portion 111.

[0072] A rotation angle sensor (not shown) is installed in the bearing portion 111. This rotation angle sensor can be of various types, such as magnetic or optical sensors. The rotation angle sensor installed in the bearing portion 111 detects the rotation angle of the shaft portion 21 and outputs an electrical signal representing the rotation angle of the shaft portion 21 to the electronic control device. Furthermore, because the pedal pad 30 and the shaft 20 are fixed to each other and rotate as a single unit, the rotation angle of the shaft portion 21 of the shaft 20 is the same as the rotation angle of the pedal pad 30.

[0073] The fixing part 22 of the shaft 20 is fixed to the pedal pad 30 in a non-rotatable manner. For example, the fixing part 22 is formed by bending into an L-shape. In this embodiment, the fixing part 22 is fixed to the side of the pedal pad 30 opposite to the side that bears the pedal force from the driver 81, i.e., the back surface 302 of the pedal, by a fixing fitting 24. The connecting part 23 is the part that connects the shaft part 21 and the fixing part 22.

[0074] The shaft 20 is rotatably supported by a bearing portion 111 provided in the housing body 11. Specifically, the shaft portion 21 of the shaft 20 is rotatably supported by the bearing portion 111, thereby supporting the shaft 20 in the housing 10 and enabling it to rotate relative to the housing 10 about the pedal axis CL. Furthermore, the shaft 20 is supported only by the bearing portion 111 provided in the housing body 11 and is not supported by the housing cover 12.

[0075] The pedal pad 30 is a component in the pedal device 1 that is operated by the driver 81 from a predetermined operating side. In this embodiment, the pedal pad 30 is made of metal, for example, and is formed into a plate shape with its thickness direction perpendicular to the pedal axis CL. Furthermore, the pedal pad 30 is configured such that one side of its thickness direction is the operating side, and the other side of its thickness direction is the opposite side, i.e., the reverse operating side. The pedal pad 30 has a pedal surface 301 facing the operating side and a pedal back surface 302 facing the reverse operating side.

[0076] In addition, the pedal pad 30 is configured at an angle relative to the vehicle's longitudinal direction Da. Specifically, the pedal pad 30 is configured such that when the pedal pad 30 is not pressed, the upper end 303 of the pedal pad 30 is positioned closer to the front of the vehicle than the lower end 304.

[0077] Furthermore, the pedal pad 30 has a thick-walled portion 305 disposed above the vehicle. This thick-walled portion 305 is configured as a part to be stepped on by the driver 81, includes the upper end portion 303 of the pedal pad 30, and is disposed above the vehicle above the pedal axis CL. The pedal surface 301 reaches the thick-walled portion 305, and the surface of the pedal surface 301 formed on the operating side of the thick-walled portion 305 functions as a tread surface 301a stepped on by the driver 81. The tread surface 301a of the pedal pad 30 is a part of the pedal surface 301. Moreover, the pedal pad 30 is not limited to... Figure 2 and Figure 3 The configuration shown can also be configured perpendicular to the vehicle's longitudinal direction (Da).

[0078] As described above, since the pedal pad 30 is fixed relative to the shaft 20, the pedal pad 30 rotates together with the shaft 20. Therefore, the pedal pad 30 rotates around the pedal axis CL as the driver 81 depresses the pedal. In detail, because the pedal pad 30 rotates within a limited, predetermined rotation angle range of less than one revolution, the pedal pad 30 oscillates around the pedal axis CL as the driver 81 depresses the pedal.

[0079] Specifically, the rotation angle range of the pedal pad 30 is the range from the minimum rotation position to the maximum rotation position of the pedal pad 30. That is, when the pedal pad 30 is not pressed, the rotation angle of the pedal pad 30 is the minimum rotation position, and when the pedal pad 30 is pressed to the maximum extent by the driver 81, the rotation angle of the pedal pad 30 is the maximum rotation position.

[0080] For example, within the aforementioned rotation angle range, the pedal pad 30 rotates such that as the force applied to it by the driver 81 from the operating side increases, the upper end 303 of the pedal pad 30 moves further forward and downward toward the vehicle. Conversely, the pedal pad 30 rotates such that as the force applied to it by the driver 81 from the operating side decreases, the upper end 303 of the pedal pad 30 moves further backward and upward toward the vehicle due to the action of the reaction force generating mechanism 50.

[0081] In this embodiment, the minimum rotational position of the pedal pad 30 is defined by the fully closed stop 32, which serves as the first stop, and the maximum rotational position of the pedal pad 30 is defined by the fully open stop 33, which serves as the second stop. The fully closed stop 32 and the fully open stop 33 are respectively made of resin or rubber.

[0082] The fully enclosed stop 32 is located in the housing 10 at a position relative to the pedal axis CL, which is positioned behind the vehicle. Specifically, the rearward portion of the fully enclosed stop 32 in the housing 10 is embedded in a wall 18 facing the rear of the vehicle and diagonally above it. When the pedal pad 30 is not pressed, the fully enclosed stop 32 contacts the lower end 304 or its vicinity in the back of the pedal 302, holding the pedal pad 30 in a position of minimal rotation.

[0083] The fully open stop 33 is located in the housing 10 at the front of the vehicle relative to the pedal axis CL. Specifically, the fully open stop 33 is located at the upper end 19 of the wall in the housing 10 facing the front of the vehicle. More specifically, the portion of the fully open stop 33 in the housing 10 facing the front of the vehicle is embedded in the wall facing the rear of the vehicle and diagonally above the vehicle. When the pedal pad 30 is depressed to its maximum extent, the fully open stop 33 contacts the upper end 303 or its vicinity in the back of the pedal 302, holding the pedal pad 30 in the maximum rotation position.

[0084] like Figure 2 and Figure 3 As shown, the reaction force generating mechanism 50 is positioned on the reverse operation side relative to the pedal pad 30 and is housed within the housing 10. The reaction force generating mechanism 50 has multiple spring components 511, 512, and 513, which generate a reaction force relative to the pedal force applied by the driver 81 to the pedal pad 30 through elastic deformation. For example, the multiple spring components 511, 512, and 513 are interconnected such that all of them elastically deform when the reaction force generating mechanism 50 generates a reaction force relative to the pedal force.

[0085] In this embodiment, the reaction force generating mechanism 50 comprises a first spring component 511 as a leaf spring, a second spring component 512 as a compression coil spring, and a third spring component 513 as a compression coil spring. Furthermore, one end of the first spring component 511 is fixed to the outer casing 11 by means of a threaded fastener or the like, thereby supporting the reaction force generating mechanism 50 within the outer casing 10.

[0086] like Figures 3-5 As shown, arm 40 is positioned between pedal pad 30 and reaction force generating mechanism 50, serving as a connecting link between the pedal pad 30 and reaction force generating mechanism 50. Furthermore, arm 40 transmits the pedal force applied to the pedal pad 30 by the driver 81 to the reaction force generating mechanism 50. In other words, arm 40 transmits the reaction force generated by reaction force generating mechanism 50 in response to the pedal force applied by driver 81 to pedal pad 30. Specifically, the phrase "arm 40 is positioned between pedal pad 30 and reaction force generating mechanism 50" refers to the arm 40 being positioned between the pedal pad 30 and reaction force generating mechanism 50 in the force transmission path.

[0087] Additionally, arm 40 has one end portion 401, another end portion 402, and a main body portion 403. Furthermore, Figure 4 Although it is a sectional view, arm 40 is not shown in sectional view for ease of observation.

[0088] One end portion 401 of the arm is located on the operating side of the arm 40, and the other end portion 402 of the arm is located on the reverse operating side of the arm 40. Furthermore, a main body portion 403 is disposed between the one end portion 401 and the other end portion 402, connecting the two ends. That is, the main body portion 403 is formed to extend from the one end portion 401 towards the reverse operating side. In other words, the main body portion 403 is formed to extend from the one end portion 401 to the other end portion 402.

[0089] The arm 40 is connected to the pedal pad 30 at one end 401. Specifically, the arm 40 is connected to the back of the pedal 302 in the pedal pad 30. Furthermore, for example... Figure 3 As shown, the arm 40 can swing relative to the pedal pad 30 with one end 401 of the arm as the center when viewed from the direction along the pedal axis CL.

[0090] On the other hand, the arm 40 is connected to the reaction force generating mechanism 50 at its other end 402. That is, the arm 40 is connected to the reaction force generating mechanism 50 on the reverse operation side. Specifically, the reaction force generating mechanism 50 has an arm receiving portion 514 located between a plurality of spring members 511, 512, 513 and the arm 40, and the other end 402 of the arm is embedded in a recess formed in this arm receiving portion 514. Furthermore, for example, as... Figure 3 As shown, the arm 40 can swing about the other end 402 of the arm relative to the arm support 514 of the reaction force generating mechanism 50 from a perspective along the direction of the pedal axis CL.

[0091] In this way, arm 40 connects pedal pad 30 and reaction force generating mechanism 50. Therefore, as the driver 81 depresses the pedal, the upper end 303 of pedal pad 30 moves further towards the reaction operation side, and arm 40 also moves further towards the reaction operation side. Moreover, the further arm 40 moves towards the reaction operation side, the more elastically deformed the multiple spring components 511, 512, and 513 of reaction force generating mechanism 50 become. Therefore, the reaction force generated by reaction force generating mechanism 50 against the driver 81's pedaling force based on this elastic deformation becomes larger.

[0092] When referring to the shape of the end 401 of the arm, such as Figures 5-7 As shown, one end portion 401 of the arm is formed to widen on both sides from the arm body portion 403 in a widening direction Dw perpendicular to the extending direction Ds of the arm body portion 403. Furthermore, in the description of this embodiment, the extending direction Ds of the arm body portion 403 is also referred to as the arm extending direction Ds, and the widening direction Dw of the one end portion 401 of the arm is also referred to as the arm end widening direction Dw.

[0093] Specifically, in this embodiment, the arm end widening direction Dw is the same as the direction along the pedal axis CL, i.e., the axial direction of the pedal axis CL. Furthermore, one end 401 of the arm is formed into a cylindrical shape with an axis parallel to the pedal axis CL. Therefore, from a perspective along the arm end widening direction Dw (e.g., along...), Figure 4 (From the perspective of the direction of arrow V), one end of the arm is 401 as shown. Figure 5 It forms a circular shape as shown.

[0094] like Figures 4-7 As shown, one end of the arm 401 has a widening end 401a disposed on one side of the arm end widening direction Dw and a widening end 401b disposed on the other side of the arm end widening direction Dw. For example, the widening end 401a is an end face disposed on one side of the arm end widening direction Dw in the cylindrical shape of the arm end 401, and the widening end 401b is an end face disposed on the other side of the arm end widening direction Dw in the cylindrical shape of the arm end 401.

[0095] like Figure 3 and Figure 4As shown, the anti-detachment part 56 is configured as a separate part from the pedal pad 30 and is joined and fixed to the pedal pad 30. In this embodiment, the anti-detachment part 56 is made of metal and is joined to the pedal pad 30, for example, by welding. The anti-detachment part 56 maintains the connection between the arm 40 and the pedal pad 30 by fixing it relative to the pedal pad 30. Furthermore, in this embodiment, the anti-detachment part 56 corresponds to one of the pedal pad 30 and the anti-detachment part 56, i.e., one part, while the pedal pad 30 corresponds to the other of the pedal pad 30 and the anti-detachment part 56, i.e., the other part.

[0096] like Figure 4 , Figure 8 , Figure 9 As shown, the anti-detachment part 56 has a base 561 and a protrusion 563. The base 561 extends from the protrusion 563 to one side and the other side in the arm end widening direction Dw.

[0097] The base 561 has a mating surface 561a on the operating side opposite the pedal back surface 302, which is fixed to the pedal back surface 302 by welding. That is, the anti-slip part 56 and the pedal pad 30 are joined together by welding between the base 561 (which is a metal part) and the metal part of the pedal pad 30 forming the pedal back surface 302. The welded portion between the anti-slip part 56 and the pedal pad 30 is provided on both sides of the arm end widening direction Dw relative to the protrusion 563. Furthermore, Figure 10 Is with Figure 4 The same sectional view, in Figure 10 In the diagram, the welded area between the anti-slip part 56 and the pedal pad 30 is indicated by a thick solid line Lw.

[0098] like Figure 4 , Figure 8 , Figure 9 As shown, the base 561 has a base surface 561b located on the side opposite to the mating surface 561a and facing the reverse operation side, and a protrusion 563 protrudes from the base surface 561b in the normal direction Dv of the base surface 561b.

[0099] like Figure 4 , Figure 8 , Figure 9 , Figure 11 As shown, a receiving space 563a for receiving one end portion 401 of the arm is formed inside the protrusion 563. That is, the protrusion 563 is a receiving portion for receiving one end portion 401 of the arm. Moreover, the protrusion 563 has a first placement portion 564 at the top of its protruding shape, which is positioned on the reverse operation side relative to the arm end portion 401 within the receiving space 563a. In this first placement portion 564, an insertion hole 564a is formed that connects to the receiving space 563a and allows the arm body portion 403 to be inserted. In addition, in the normal direction Dv of the base surface 561b (refer to...) Figure 9 On the surface, the accommodating space 563a is, for example, set to reach a position further to the reverse operation side than the base surface 561b.

[0100] To put it another way, the receiving space 563a formed in the anti-slip part 56 is recessed from the operating side to the opposite operating side to receive one end of the arm 401. Furthermore, the receiving space 563a is connected to the insertion hole 564a at its bottom 563c. On the other hand, the receiving space 563a has a receiving space opening 563d that opens to the side opposite to the insertion hole 564a (i.e., the operating side). This receiving space opening 563d is covered by the second configuration portion 306 of the pedal pad 30. Moreover, this second configuration portion 306 is the portion of the pedal pad 30 located on the operating side of the arm end 401, separated from the first configuration portion 564.

[0101] Because the first configuration part 564 and the second configuration part 306 are configured in this way, the first configuration part 564 and the second configuration part 306 hold the arm end 401 on the pedal pad 30 in a state where the arm end 401 is sandwiched between the first configuration part 564 and the second configuration part 306.

[0102] In detail, the first configuration part 564 has a one-side receiving part 564b disposed on one side of the arm end widening direction Dw relative to the insertion hole 564a, and a other-side receiving part 564c disposed on the other side of the arm end widening direction Dw relative to the insertion hole 564a. Moreover, the first configuration part 564 and the second configuration part 306 hold the arm end 401 on the pedal pad 30 in a state in which the arm end 401 is sandwiched between the one-side receiving part 564b and the second configuration part 306 and between the other-side receiving part 564c and the second configuration part 306.

[0103] Additionally, one receiving portion 564b has a receiving surface 564d facing the operating side and towards the receiving space 563a, and the other receiving portion 564c has a receiving surface 564e facing the operating side and towards the receiving space 563a. The receiving surface 564d is disposed on one side of the arm end widening direction Dw relative to the insertion hole 564a, and the receiving surface 564e is disposed on the other side of the arm end widening direction Dw relative to the insertion hole 564a. The receiving surfaces 564d and 564e can be planar in cross-section perpendicular to the arm end widening direction Dw, or they can be concave surfaces with a radius of curvature larger than the radius of the cylindrical shape of one end of the arm 401 and curved towards the opposite operating side.

[0104] In addition, Figure 8 In the diagram, one bearing surface 564d and the other bearing surface 564e are represented by dotted shaded lines. Figure 9In the diagram, one side of the receiving portion 564b is indicated by arrow A1, and the other side of the receiving portion 564c is indicated by arrow A2. Additionally, in... Figure 11 In the middle, the receiving part 564b on one side is represented by arrow A3 and dotted shading lines.

[0105] Figure 12 This describes a method for installing the aforementioned arm 40 and anti-slip part 56 onto the pedal pad 30. As such... Figure 12 As shown, first, prepare the pedal pad 30, and then prepare the arm 40 and the anti-slip part 56 as individual parts.

[0106] Next, the arm 40 is inserted into the insertion hole 564a of the first configuration portion 564 included in the anti-slip part 56. Specifically, the other end 402 of the arm 40 is inserted into the insertion hole 564a from the receiving space opening 563d side, and then the arm body portion 403 is inserted into the insertion hole 564a. Furthermore, the anti-slip part 56 is brought close to the pedal pad 30 with the mating surface 561a facing the pedal back surface 302, as shown by arrow A4.

[0107] Then, after setting the arm end 401 to be accommodated in the receiving space 563a of the anti-detachment part 56 and the mating surface 561a of the anti-detachment part 56 to be in contact with the back surface 302 of the pedal, the mating surface 561a and the back surface 302 of the pedal are joined by welding.

[0108] As shown above, arm 40 and anti-slip part 56 are installed on pedal pad 30. Therefore, as Figure 4 As shown, the insertion hole 564a of the first configuration part 564 is sized such that all parts of the arm 40 located on the reverse operation side in the arm extension direction Ds, which are further from the arm end 401 than the arm end 401, can pass through, but the arm end 401 cannot pass through. Specifically, "all parts of the arm 40 located on the reverse operation side in the arm extension direction Ds, which are further from the arm end 401" refers to the arm body part 403 and the other end 402 of the arm. Furthermore, the arm end 401 is not included among the parts located on the reverse operation side in the arm extension direction Ds, which are further from the arm end 401.

[0109] Moreover, such as Figure 4 and Figure 9 As shown, the anti-detachment component 56, as a single component, is shaped to be open on the operating side relative to the arm end 401, allowing the arm end 401 to move from the position between the first configuration portion 564 and the second configuration portion 306 toward the operating side. In summary, the receiving space opening 563d of the anti-detachment component 56 is the size through which the arm end 401 can pass.

[0110] Next, the operation of the pedal device 1 described above will be explained. For example... Figures 1-3As shown, if the driver 81 presses the pedal pad 30, thereby applying the driver 81's pedal force to the pedal surface 301a, the pedal pad 30 rotates about the pedal axis CL in such a way that the upper end 303 moves towards the opposite operation side. At this time, as... Figure 3 and Figure 4 As shown, because the second configuration part 306 of the pedal pad 30 presses one end 401 of the arm on the reverse operation side, the rotation angle of the pedal pad 30 is transmitted to the reaction force generating mechanism 50 via the arm 40 as a displacement corresponding to the rotation angle.

[0111] Therefore, the more the pedal pad 30 rotates around the pedal axis CL in a manner that moves the upper end 303 toward the opposite operation side, the more significantly the multiple spring components 511, 512, and 513 of the reaction force generating mechanism 50 undergo elastic deformation. As a result, the more the pedal pad 30 is rotated from its minimum rotation position by the driver 81's pedal operation, the greater the reaction force generated by the reaction force generating mechanism 50 against the driver 81's pedaling force.

[0112] The pedal device 1 of this embodiment described above achieves the following effects.

[0113] According to this embodiment, such as Figure 3 and Figure 4 As shown, the anti-detachment part 56 is configured as a separate part from the pedal pad 30 and is fixed relative to the pedal pad 30. Moreover, the first configuration portion 564 of the anti-detachment part 56 and the second configuration portion 306 of the pedal pad 30 hold the arm end 401 to the pedal pad 30 in a state where the arm end 401 is sandwiched between the first configuration portion 564 and the second configuration portion 306.

[0114] Therefore, since the first mounting portion 564 and the second mounting portion 306 are different parts, it is possible to ensure that the first mounting portion 564 can withstand the external force and bear the width of the arm end 401 when an external force is applied to the arm end 401 in the direction of pressing the first mounting portion 564. Therefore, compared with the structure of the pedal device in Patent Document 1, for example, the arm 40 can be connected to the pedal pad 30 with sufficient strength. That is, the arm 40 will not detach from the pedal pad 30 and will always follow the rotation of the pedal pad 30, thus improving the reliability of the pedal device 1.

[0115] In addition, such as Figure 9 As shown, the aforementioned bearing width of the first configuration part 564 that supports the arm end 401 against external forces refers, for example, to the width of one bearing part 564b and the width of the other bearing part 564c, and refers to the width of the bearing part 564b. Figure 9 Arrows A1 and A2 indicate the width.

[0116] (1) In addition, according to this embodiment, such as Figure 12As shown, the insertion hole 564a of the anti-detachment component 56 is a size that allows all parts of the arm 40 located on the anti-operation side in the arm extension direction Ds, which is further from the arm end 401 than the arm end 401, to pass through, while the arm end 401 cannot pass through. Furthermore, the anti-detachment component 56, as a single component, is shaped to be open on the operation side relative to the arm end 401, allowing the arm end 401 to move from a position between the first placement portion 564 and the second placement portion 306 towards the operation side. In other words, the receiving space opening 563d of the anti-detachment component 56 is a size that allows the arm end 401 to pass through.

[0117] Therefore, when installing the arm 40 and the anti-slip part 56 onto the pedal pad 30, as Figure 12 As shown, the arm 40 can be inserted into the insertion hole 564a of the anti-detachment part 56 from the operating side relative to the anti-detachment part 56. Therefore, it is possible to... Figure 9 The width of the receiving portion 564b on one side, indicated by arrow A1, and the width of the receiving portion 564c on the other side, indicated by arrow A2, are set to a sufficient size to prevent one end 401 of the arm from detaching. For example, this can prevent the arm 40 from detaching from the pedal pad 30 due to the elastic deformation of the receiving portion 564b on one side and the receiving portion 564c on the other side, thereby improving the reliability of the pedal device 1.

[0118] (2) Furthermore, according to this embodiment, because Figure 4 The anti-detachment part 56 shown is made of metal, so the first mounting portion 564, which constitutes part of the anti-detachment part 56, is also made of metal. Therefore, the rigidity of the first mounting portion 564 for holding one end of the arm 401 within the receiving space 563a can be improved, thus preventing the arm 40 from falling off due to elastic deformation of the first mounting portion 564 and improving the reliability of the pedal device 1.

[0119] (3) In addition, according to this embodiment, such as Figure 10 As shown, the pedal pad 30 and the anti-slip part 56 each have metal parts, and are joined together by welding these metal parts. Therefore, the arm 40 and the anti-slip part 56 can be assembled to the pedal pad 30 in a simple manner. Moreover, the anti-slip part 56 can be fixed to the pedal pad 30 without protruding protrusions on the pedal surface 301.

[0120] (4) In addition, according to this embodiment, such as Figure 1 As shown, the pedal device 1 is provided in the vehicle 80 as a brake pedal device for performing braking operations to brake the vehicle 80. Therefore, the high reliability of the pedal device 1, which prevents the arm 40 from disengaging from the pedal pad 30, can be fully and effectively utilized in the vehicle 80.

[0121] (5) In addition, according to this embodiment, such as Figures 4-7As shown, the arm-end widening direction Dw is along the pedal axis CL (refer to...). Figure 3 Furthermore, from the perspective of the direction along the widening direction Dw of the arm end (e.g., along the direction of the arm end widening direction Dw), Figure 4 From the perspective of the direction of arrow V, one end of the arm 401 forms a circular shape. Therefore, from the perspective of the direction along the pedal axis CL, the arm 40 can swing relative to the pedal pad 30 with the arm end 401 as the center.

[0122] <Second Implementation Method>

[0123] Next, the second embodiment will be described. In this embodiment, the differences from the first embodiment described above will be mainly explained. In addition, parts that are the same as or equivalent to those in the previous embodiment will be omitted or simplified in the description. This will also be the case in the description of the embodiments described later. Furthermore, in the drawings referred to after the second embodiment, the various structures of the pedal device 1 are shown in a simplified manner.

[0124] like Figure 13 As shown, in this embodiment, the pedal pad 30 is constructed with an overall uniform thickness. Therefore, the pedal surface 301 of the pedal pad 30 functions as a tread surface 301a.

[0125] Apart from the above description, this embodiment is the same as the first embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the first embodiment can be obtained as in the first embodiment.

[0126] <Third Implementation Method>

[0127] Next, the third embodiment will be described. In this embodiment, the differences from the second embodiment described above will be mainly explained.

[0128] like Figure 14 and Figure 15 As shown, in this embodiment, the pedal device 1 does not have Figure 4 The anti-slip part 56. Instead, in this embodiment, the pedal device 1 includes an anti-slip part 60, and the pedal pad 30 has a protrusion 563 (see reference) instead of the protrusion 563 in the second embodiment. Figure 4 ) the protrusion 35.

[0129] The protrusion 35 in this embodiment corresponds to the protrusion 563 in the second embodiment. That is, the protrusion 35 in this embodiment differs from the protrusion 563 in the second embodiment in that it constitutes part of the pedal pad 30, but in other respects, it has the same structure as the protrusion 563 in the second embodiment.

[0130] Specifically, such as Figure 15 and Figure 9 As shown, the receiving space 35a of this embodiment is the same as the receiving space 563a of the second embodiment, and the bottom 35c of the receiving space 35a of this embodiment is the same as the bottom 563c of the receiving space 563a of the second embodiment. Furthermore, the receiving space opening 35d of this embodiment is the same as the receiving space opening 563d of the second embodiment, and the first placement part 36 of this embodiment is the same as the first placement part 564 of the second embodiment. Additionally, the insertion hole 36a of the first placement part 36 of this embodiment is the same as the insertion hole 564a of the first placement part 564 of the second embodiment. Furthermore, one side receiving part 36b of the first placement part 36 of this embodiment is the same as one side receiving part 564b of the first placement part 564 of the second embodiment, and the other side receiving part 36c of the first placement part 36 of this embodiment is the same as the other side receiving part 564c of the first placement part 564 of the second embodiment. Furthermore, one side receiving surface 36d of the first configuration portion 36 in this embodiment is the same as one side receiving surface 564d of the first configuration portion 564 in the second embodiment, and the other side receiving surface 36e of the first configuration portion 36 in this embodiment is the same as the other side receiving surface 564e of the first configuration portion 564 in the second embodiment. In addition, in Figure 15 In, also with Figure 9 Similarly, one side receiving portion 36b of the first configuration portion 36 is indicated by arrow A1, and the other side receiving portion 36c of the first configuration portion 36 is indicated by arrow A2.

[0131] Therefore, each structure included in the protrusion 35 of this embodiment corresponds to each structure included in the protrusion 563 of the second embodiment. Furthermore, the pedal pad 30 of this embodiment has a first mounting portion 36 included in the protrusion 35. In this embodiment, the pedal pad 30 corresponds to a part having the first mounting portion 36.

[0132] Furthermore, in this embodiment, the protrusion 35 of the pedal pad 30 protrudes from a portion of the pedal back surface 302, namely the base surface 302a, in the normal direction Dv of the base surface 302a. The base surface 302a of this embodiment is the portion of the pedal back surface 302 provided around the protrusion 35. The base surface 302a of this embodiment corresponds to the base surface 561b of the second embodiment, and is identical to the base surface 561b except that it forms part of the pedal pad 30.

[0133] like Figure 14 and Figure 15 As shown, the anti-detachment part 60 is made of metal, for example, and has a second mounting portion 37, a one-side joining portion 601, and a other-side joining portion 602. In this embodiment, the anti-detachment part 60 corresponds to another part having the second mounting portion 37.

[0134] The second configuration part 37 of this embodiment corresponds to the second configuration part 306 of the second embodiment. That is, the second configuration part 37 of this embodiment differs from the second configuration part 306 of the second embodiment in that it constitutes part of the anti-detachment part 60, but is the same as the second configuration part 306 of the second embodiment in other aspects. For example, the second configuration part 37 of this embodiment is disposed on the operating side of the first configuration part 36 across one end 401 of the arm.

[0135] One side joint 601 of the anti-slip part 60 is disposed on one side of the arm end widening direction Dw relative to the second configuration part 37. The other side joint 602 is disposed on the other side of the arm end widening direction Dw relative to the second configuration part 37. This one side joint 601 and the other side joint 602 contact the pedal surface 301. Furthermore, the one side joint 601 and the other side joint 602 are joined to the pedal surface 301, for example, by welding. That is, the pedal pad 30 and the anti-slip part 60 are joined together by welding the metal portion forming the pedal surface 301 and the one side and the other side joints 601 and 602, which are metal portions. Furthermore, Figure 16 Is with Figure 14 The same sectional view, in Figure 16 In the middle, the welded part of the anti-slip part 60 and the pedal pad 30 is represented by the thick solid line Lw.

[0136] Figure 17 This describes a method for installing the aforementioned anti-slip component 60 and arm 40 onto the pedal mat 30. For example... Figure 17 As shown, first, prepare the pedal pad 30, and then prepare the arm 40 and the anti-slip part 60 as individual parts.

[0137] Next, the arm 40 is positioned with one end 401 facing the operating side, and then the arm 40 is inserted into the insertion hole 36a of the first configuration part 36. Specifically, the other end 402 of the arm 40 is inserted into the insertion hole 36a from the receiving space opening 35d side, and then the arm body 403 is inserted into the insertion hole 36a. Furthermore, with the anti-slip member 60 positioned so that the side that will engage with the pedal surface 301 is facing the pedal surface 301, as shown by arrow A5, the pedal pad 30 and the anti-slip member 60 are brought close together.

[0138] Then, one end 401 of the arm is accommodated in the receiving space 35a of the pedal pad 30, and the joints 601 and 602 on one and the other side of the anti-slip part 60 are brought into contact with the pedal surface 301. After the pedal pad 30, the arm 40 and the anti-slip part 60 are positioned in this way, the joints 601 and 602 on one and the other side of the anti-slip part 60 are joined to the pedal surface 301 by welding.

[0139] As described above, the anti-slip part 60 and the arm 40 are installed on the pedal mat 30. Therefore, the size relationship between the insertion hole 36a of the first configuration part 36 and the arm end 401, as well as the size relationship between the receiving space opening 35d and the arm end 401, are the same as in the second embodiment.

[0140] Specifically, such as Figure 14 As shown, the through hole 36a is a size that allows all parts of the arm 40, located on the reverse operation side further along the arm extension direction Ds than the arm end 401, to pass through, but the arm end 401 cannot pass through. Furthermore, as... Figure 14 and Figure 15 As shown, the pedal pad 30, as a single component, is shaped to be open on the operating side relative to the arm end 401, allowing the arm end 401 to move from a position between the first configuration portion 36 and the second configuration portion 37 toward the operating side. In summary, the accommodating space opening 35d of the pedal pad 30 is the size through which the arm end 401 can pass.

[0141] Apart from the above description, this embodiment is the same as the second embodiment. Furthermore, in this embodiment, the same effects achieved by the structure common to the second embodiment can be obtained as in the second embodiment. In addition, this embodiment is a variation based on the second embodiment, but it is also possible to combine this embodiment with the first embodiment described above.

[0142] <Fourth Implementation Method>

[0143] Next, the fourth embodiment will be described. In this embodiment, the differences from the second embodiment described above will be mainly explained.

[0144] like Figure 18 As shown, in this embodiment, the method of joining the pedal pad 30 and the anti-slip part 56 is to press in the bosses 565a and 565b instead of welding.

[0145] Specifically, the anti-slip component 56, as a part, has a plurality of bosses 565a and 565b protruding from the base 561 toward the pedal pad 30 side. One of the plurality of bosses 565a and 565b, namely the side boss 565a, is disposed on one side of the arm end widening direction Dw relative to the protrusion 563. Moreover, the other of the plurality of bosses 565a and 565b, namely the other side boss 565b, is disposed on the other side of the arm end widening direction Dw relative to the protrusion 563.

[0146] Additionally, on the pedal pad 30, which is another component, there are a connecting hole 30a on one side and a connecting hole 30b on the other side, which extend from the pedal surface 301 to the pedal back surface 302. The connecting hole 30a on one side is coaxial with the boss 565a on one side, and the connecting hole 30b on the other side is coaxial with the boss 565b on the other side.

[0147] Furthermore, one side boss 565a is pressed into one side connecting hole 30a from the back side 302 of the pedal towards the pedal surface 301, and the other side boss 565b is pressed into the other side connecting hole 30b from the back side 302 of the pedal towards the pedal surface 301.

[0148] In this way, the anti-slip part 56 and the pedal pad 30 are joined together by pressing one side boss 565a into one side connecting hole 30a and the other side boss 565b into the other side connecting hole 30b.

[0149] (1) As described above, according to this embodiment, the anti-detachment part 56 and the pedal pad 30 are joined together by pressing the bosses 565a and 565b into the connecting holes 30a and 30b. Therefore, the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple manner.

[0150] Apart from the above description, this embodiment is the same as the second embodiment. Furthermore, in this embodiment, the same effects achieved by the structure common to the second embodiment can be obtained as in the second embodiment. In addition, this embodiment is a variation based on the second embodiment, but it is also possible to combine this embodiment with the first embodiment described above.

[0151] <Fifth Implementation Method>

[0152] Next, the fifth embodiment will be described. In this embodiment, the differences from the aforementioned third embodiment will be mainly explained.

[0153] like Figure 19 As shown, in this embodiment, the method of joining the pedal pad 30 and the anti-slip part 60 is the same as that of the fourth embodiment, which is pressing in, rather than welding.

[0154] Specifically, the anti-slip component 60, which is another part, has a side boss 603a protruding from a side joint 601 toward the pedal pad 30 side and a side boss 603b protruding from the other side joint 602 toward the pedal pad 30 side. The side boss 603a is disposed on one side of the arm end widening direction Dw relative to the second configuration part 37, and the other side boss 603b is disposed on the other side of the arm end widening direction Dw relative to the second configuration part 37.

[0155] Additionally, the pedal pad 30, which is a component, has a connecting hole 30c on one side and a connecting hole 30d on the other side, extending from the pedal surface 301 to the pedal back surface 302. The connecting hole 30c on one side is coaxial with a boss 603a on one side, and the connecting hole 30d on the other side is coaxial with a boss 603b on the other side.

[0156] Furthermore, one side boss 603a is pressed into one side connecting hole 30c from the pedal surface 301 side to the pedal back side 302 side, and the other side boss 603b is pressed into the other side connecting hole 30d from the pedal surface 301 side to the pedal back side 302 side.

[0157] In this way, the anti-slip part 60 and the pedal pad 30 are joined together by pressing one side boss 603a into one side connecting hole 30c and the other side boss 603b into the other side connecting hole 30d.

[0158] (1) As described above, according to this embodiment, the anti-slip part 60 and the pedal pad 30 are joined together by the same pressing as in the fourth embodiment. Therefore, the effect based on this pressing can be obtained in the same way as in the fourth embodiment.

[0159] Apart from the above description, this embodiment is the same as the third embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the third embodiment can be obtained.

[0160] <Sixth Implementation Method>

[0161] Next, the sixth embodiment will be described. In this embodiment, the differences from the aforementioned fourth embodiment will be mainly explained.

[0162] like Figure 20 As shown, the connecting hole 30a on one side and the connecting hole 30b on the other side of the pedal pad 30 are non-through holes, rather than through holes. That is, in each of the connecting holes 30a on one side and 30b on the other side, the pedal surface 301 side is closed.

[0163] As described above, according to this embodiment, the connecting hole 30a on one side and the connecting hole 30b on the other side are both non-through holes. Therefore, without protruding protrusions on the side of the pedal mat 30 that is stepped on by the driver 81, i.e., the pedal surface 301, the anti-slip part 56 can be fixed to the pedal mat 30.

[0164] Apart from the above description, this embodiment is the same as the fourth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fourth embodiment can be obtained.

[0165] <Seventh Implementation Method>

[0166] Next, the seventh embodiment will be described. In this embodiment, the differences from the fifth embodiment described above will be mainly explained.

[0167] like Figure 21 As shown, the connecting hole 30c on one side and the connecting hole 30d on the other side of the pedal pad 30 are non-through holes, rather than through holes. That is, in each of the connecting holes 30c on one side and 30d on the other side, the back side 302 of the pedal is closed.

[0168] Apart from the above description, this embodiment is the same as the fifth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fifth embodiment can be obtained.

[0169] <Eighth Implementation Method>

[0170] Next, the eighth embodiment will be described. In this embodiment, the differences from the aforementioned fourth embodiment will be mainly explained.

[0171] like Figure 22 As shown, in this embodiment, the method of joining the pedal pad 30 and the anti-slip part 56 is to use the riveting of the bosses 565a and 565b, rather than the pressing of the bosses 565a and 565b.

[0172] Specifically, since the anti-slip part 56 is made of metal, both the one-side boss 565a and the other-side boss 565b are also made of metal. After the one-side boss 565a is inserted from the back side 302 of the pedal towards the pedal surface 301, it is riveted to the pedal surface 301 side of the one-side boss 565a. That is, a one-side riveting portion 565c with a larger diameter than the one-side connecting hole 30a is formed on the pedal surface 301 side of the one-side boss 565a.

[0173] The other boss 565b is the same. That is, after the other boss 565b is inserted from the back side 302 of the pedal towards the pedal surface 301 side into the other connecting hole 30b, which serves as a through hole, the pedal surface 301 side of the other boss 565b is riveted. That is, a riveting portion 565d with an enlarged diameter compared to the other connecting hole 30b is formed on the pedal surface 301 side of the other boss 565b.

[0174] In this way, the anti-slip part 56 and the pedal pad 30 are joined together by riveting the bosses 565a and 565b.

[0175] (1) As described above, according to this embodiment, the anti-detachment part 56 and the pedal pad 30 are joined together by riveting of the bosses 565a and 565b, so the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple way.

[0176] Apart from the above description, this embodiment is the same as the fourth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fourth embodiment can be obtained.

[0177] <Ninth Implementation Method>

[0178] Next, the ninth embodiment will be described. In this embodiment, the differences from the fifth embodiment described above will be mainly explained.

[0179] like Figure 23 As shown, in this embodiment, the same riveting method as in the eighth embodiment is used as the method of joining the pedal pad 30 and the anti-slip part 60, instead of pressing in the bosses 603a and 603b.

[0180] Specifically, since the anti-slip part 60 is made of metal, both the one-sided boss 603a and the other-sided boss 603b are also made of metal. After the one-sided boss 603a is inserted from the pedal surface 301 side to the pedal back side 302 side into the one-sided connecting hole 30c, which serves as a through hole, the pedal back side 302 side of the one-sided boss 603a is riveted. That is, a one-sided riveting portion 603c with a larger diameter than the one-sided connecting hole 30c is formed on the pedal back side 302 side of the one-sided boss 603a.

[0181] The other boss 603b is the same. That is, after the other boss 603b is inserted from the pedal surface 301 side to the pedal back surface 302 side into the other connecting hole 30d, which serves as a through hole, the pedal back surface 302 side of the other boss 603b is riveted. That is, on the pedal back surface 302 side of the other boss 603b, a riveting portion 603d with a larger diameter than the other connecting hole 30d is formed.

[0182] In this way, the anti-slip part 56 and the pedal pad 30 are joined together by the riveting of the bosses 603a and 603b.

[0183] (1) As described above, according to this embodiment, the anti-detachment part 60 and the pedal pad 30 are joined together by the same riveting as in the eighth embodiment. Therefore, the same effect based on this riveting can be obtained as in the eighth embodiment.

[0184] Apart from the above description, this embodiment is the same as the fifth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fifth embodiment can be obtained.

[0185] <Tenth Implementation Method>

[0186] Next, the tenth embodiment will be described. In this embodiment, the differences from the aforementioned fourth embodiment will be mainly explained.

[0187] like Figure 24 As shown, in this embodiment, the pedal pad 30 and the anti-slip part 56 are joined by threaded fixing instead of pressing in the bosses 565a and 565b.

[0188] Specifically, on the side of the anti-slip part 56 in the arm-end widening direction Dw relative to the protrusion 563, the base 561 of the anti-slip part 56 is threadedly fixed to the pedal pad 30 by a one-sided screw 381. More specifically, the one-sided screw 381 is inserted into a through hole formed in the base 561, i.e., a one-sided screw insertion hole 561c, and engages with a one-sided threaded hole 30e provided on the pedal pad 30 and having internal threads.

[0189] On the other side of the anti-slip part 56, in the arm-end widening direction Dw relative to the protrusion 563, the same applies. That is, on the other side of the arm-end widening direction Dw relative to the protrusion 563, the base 561 of the anti-slip part 56 is threadedly fixed to the pedal pad 30 by a screw 382. Specifically, the screw 382 is inserted into a through hole formed in the base 561, namely the screw insertion hole 561d, and engages with a threaded hole 30f provided on the pedal pad 30 and having internal threads.

[0190] (1) As described above, according to this embodiment, the pedal pad 30 and the anti-detachment part 56 are joined together by threaded fastening, so the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple way.

[0191] Apart from the above description, this embodiment is the same as the fourth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fourth embodiment can be obtained.

[0192] <Eleventh Implementation Method>

[0193] Next, the eleventh embodiment will be described. In this embodiment, the differences from the fifth embodiment described above will be mainly explained.

[0194] like Figure 25As shown, in this embodiment, the method of joining the pedal pad 30 and the anti-slip part 60 is to use the same threaded fixing as in the tenth embodiment, instead of pressing in the bosses 603a and 603b.

[0195] Specifically, on the side of the pedal pad 30 in the arm-end widening direction Dw relative to the protrusion 35, a one-sided engagement portion 601 of the anti-slip part 60 is threadedly fixed to the pedal pad 30 by a one-sided screw 381. More specifically, the one-sided screw 381 is inserted into a through hole formed in the pedal pad 30, i.e., a one-sided screw insertion hole 30g, and engages with a one-sided threaded hole 601a provided in the one-sided engagement portion 601 and having internal threads.

[0196] On the other side of the arm-end widening direction Dw relative to the protrusion 35, the same applies. That is, on the other side of the arm-end widening direction Dw relative to the protrusion 35, the other side engagement portion 602 of the anti-detachment part 60 is threadedly fixed to the pedal pad 30 by a screw 382. In detail, the screw 382 is inserted into the through hole formed in the pedal pad 30, i.e., the screw insertion hole 30h, and engages with the threaded hole 602a provided in the engagement portion 602 and having internal threads.

[0197] (1) As described above, according to this embodiment, the anti-detachment part 60 and the pedal pad 30 are joined together by the same threaded fastening as in the tenth embodiment. Therefore, the same effect based on this threaded fastening can be obtained as in the tenth embodiment.

[0198] Apart from the above description, this embodiment is the same as the fifth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fifth embodiment can be obtained.

[0199] <Twelfth Implementation Method>

[0200] Next, the twelfth embodiment will be described. In this embodiment, the differences from the fourth embodiment described above will be mainly explained.

[0201] like Figure 26 As shown, in this embodiment, the method of joining the pedal pad 30 and the anti-slip part 56 is based on the joining of retaining rings 391 and 392, rather than the pressing in of bosses 565a and 565b.

[0202] Specifically, the pedal pad 30 has a one-sided boss 30i and a other-sided boss 30j protruding from the back of the pedal 302. The one-sided boss 30i is disposed on one side of the arm end widening direction Dw relative to the protrusion 563, and the other-sided boss 30j is disposed on the other side of the arm end widening direction Dw relative to the protrusion 563. Because the pedal pad 30 is made of metal, these bosses 30i and 30j are also made of metal.

[0203] In addition, a through hole 561e for inserting a boss 30i on one side and a through hole 561f for inserting a boss 30j on the other side are formed at the base 561 of the anti-detachment part 56.

[0204] Furthermore, a retaining ring 391 is embedded in an annular groove on the outer periphery of one side boss 30i, and a retaining ring 392 is embedded in an annular groove on the outer periphery of the other side boss 30j. In short, the retaining ring 391 is engaged with the one side boss 30i at a position closer to the front end of the base 561 of the anti-detachment part 56, and the retaining ring 392 is engaged with the other side boss 30j at a position closer to the front end of the other side boss 30j than the base 561 of the anti-detachment part 56.

[0205] In this way, the anti-slip part 56 and the pedal pad 30 are connected to each other by the retaining rings 391 and 392 that are locked onto the bosses 30i and 30j.

[0206] (1) As described above, according to this embodiment, the anti-detachment part 56 and the pedal pad 30 are connected to each other by retaining rings 391 and 392 that are engaged with the bosses 30i and 30j. Therefore, the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple manner.

[0207] Apart from the above description, this embodiment is the same as the fourth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fourth embodiment can be obtained.

[0208] <Thirteenth Implementation Method>

[0209] Next, the thirteenth embodiment will be described. In this embodiment, the differences from the fifth embodiment described above will be mainly explained.

[0210] like Figure 27 As shown, in this embodiment, the method of joining the pedal pad 30 and the anti-slip part 60 is the same as that of the twelfth embodiment, which is based on the retaining rings 391 and 392, instead of pressing in the bosses 603a and 603b.

[0211] Specifically, the anti-slip part 60 has a side engagement 601 with a side boss 601b protruding towards the pedal pad 30, and a side engagement 602 with a side boss 602b protruding towards the pedal pad 30. The side boss 601b is positioned relative to the protrusion 35 of the pedal pad 30 on one side in the arm end widening direction Dw, and the side boss 602b is positioned relative to the protrusion 35 on the other side in the arm end widening direction Dw. Because the anti-slip part 60 is made of metal, these bosses 601b and 602b are also made of metal.

[0212] In addition, a through hole 30k is formed on the pedal pad 30 for inserting a boss 601b on one side and a through hole 30m for inserting a boss 602b on the other side.

[0213] Furthermore, the side retaining ring 391, like in the twelfth embodiment, engages with the side boss 601b of this embodiment, which corresponds to the side boss 30i of the twelfth embodiment. The other side retaining ring 392, like in the twelfth embodiment, engages with the other side boss 602b of this embodiment, which corresponds to the other side boss 30j of the twelfth embodiment.

[0214] In this way, the anti-slip part 60 and the pedal pad 30 are connected to each other by the retaining rings 391 and 392 that are locked onto the bosses 601b and 602b.

[0215] (1) As described above, according to this embodiment, the anti-slip part 60 and the pedal pad 30 are connected to each other by retaining rings 391 and 392 in the same manner as in the twelfth embodiment. Therefore, the same effect based on the retaining rings 391 and 392 can be obtained as in the twelfth embodiment.

[0216] Apart from the above description, this embodiment is the same as the fifth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fifth embodiment can be obtained.

[0217] <Fourteenth Implementation Method>

[0218] Next, the fourteenth embodiment will be described. In this embodiment, the differences from the aforementioned eighth embodiment will be mainly explained.

[0219] like Figure 28 As shown, the anti-slip part 56 and the pedal pad 30 are joined together by thermal riveting of one side boss 565a and the other side boss 565b. In this embodiment, the anti-slip part 56 is made of thermoplastic resin instead of metal. Therefore, the one side boss 565a and the other side boss 565b are also made of thermoplastic resin.

[0220] This hot riveting does not involve melting the resin bosses 565a and 565b, but rather refers to applying pressure while heating the bosses 565a and 565b, causing them to undergo plastic deformation. Through this hot riveting, riveting portions 565c and 565d are formed at the front ends of the bosses 565a and 565b, respectively.

[0221] (1) As described above, according to this embodiment, the anti-detachment part 56 is made of resin, therefore, the first mounting part 564 is also made of resin. Therefore, wear caused by sliding on the first mounting part 564 and the end of the arm 401 can be reduced.

[0222] (2) In addition, according to this embodiment, the anti-detachment part 56 and the pedal pad 30 are joined together by thermal riveting of the bosses 565a and 565b, so the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple way.

[0223] Apart from the above description, this embodiment is the same as the eighth embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the eighth embodiment can be obtained as in the eighth embodiment.

[0224] <Fifteenth Implementation Method>

[0225] Next, the fifteenth embodiment will be described. In this embodiment, the differences from the aforementioned ninth embodiment will be mainly explained.

[0226] like Figure 29 As shown, the anti-slip part 60 and the pedal pad 30 are joined together by thermal riveting of one side boss 603a and the other side boss 603b. In this embodiment, the anti-slip part 60 is made of thermoplastic resin instead of metal. Therefore, the one side boss 603a and the other side boss 603b are also made of thermoplastic resin.

[0227] By using the hot riveting of bosses 603a and 603b, riveting portions 603c and 603d are formed at the front ends of the bosses 603a and 603b, respectively.

[0228] (1) As described above, according to this embodiment, the anti-detachment part 60 and the pedal pad 30 are joined together by the same thermal riveting as in the fourteenth embodiment. Therefore, the same effect based on this thermal riveting can be obtained as in the fourteenth embodiment.

[0229] Apart from the above description, this embodiment is the same as the ninth embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the ninth embodiment can be obtained as in the ninth embodiment.

[0230] <Sixteenth Implementation Method>

[0231] Next, the sixteenth embodiment will be described. In this embodiment, the differences from the aforementioned tenth embodiment will be mainly explained.

[0232] like Figure 30 As shown, in this embodiment, the anti-detachment part 56 is made of resin instead of metal. Therefore, the base 561 is also made of resin. Moreover, the anti-detachment part 56 has a metal insert 561g on one side and an insert 561h on the other side, which are made of resin, integrally fixed to the base 561, which is the resin part, by insert forming of the anti-detachment part 56. Furthermore, it is explicitly stated that the pedal pad 30 of this embodiment is also made of metal, just like in the tenth embodiment.

[0233] One side insert 561g is disposed on one side of the arm end widening direction Dw relative to the protrusion 563 of the anti-detachment part 56, and the other side insert 561h is disposed on the other side of the arm end widening direction Dw relative to the protrusion 563.

[0234] Furthermore, the screw insertion hole 561c for inserting a screw 381 on one side is not formed directly in the base 561, but is formed in the insert 561g on one side. Similarly, the screw insertion hole 561d for inserting a screw 382 on the other side is not formed directly in the base 561, but is formed in the insert 561h on the other side.

[0235] (1) Thus, the anti-detachment part 56 and the pedal pad 30 are joined together by threading the pedal pad 30 to the inserts 561g and 561h on one side and the other side of the anti-detachment part 56 respectively. Therefore, the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple way.

[0236] Furthermore, according to this embodiment, the seat portion of the anti-detachment part 56 pressed by the heads of screws 381 and 382 is a metal insert 561g and 561h. Therefore, compared with the case where the seat portion is made of resin, the durability of the anti-detachment part 56 can be improved.

[0237] Apart from the above description, this embodiment is the same as the tenth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the tenth embodiment can be obtained.

[0238] <Seventeenth Implementation Method>

[0239] Next, the seventeenth embodiment will be described. In this embodiment, the differences from the eleventh embodiment described above will be mainly explained.

[0240] like Figure 31As shown, in this embodiment, the anti-detachment part 60 is made of resin instead of metal. Therefore, the one-side joint 601 and the other-side joint 602 are also made of resin. Furthermore, the anti-detachment part 60 has a metal one-side insert 601c and a metal other-side insert 602c.

[0241] The insert 601c on one side is integrally fixed to the joint portion 601 on the other side, which is a resin part, by the insert forming of the anti-detachment part 60. Similarly, the insert 602c on the other side is integrally fixed to the joint portion 602 on the other side, which is a resin part, by the insert forming of the anti-detachment part 60. Furthermore, it is explicitly stated that the pedal pad 30 of this embodiment is constructed of metal, similar to that of the eleventh embodiment.

[0242] One side insert 601c is disposed on one side of the protrusion 35 of the pedal pad 30 in the arm end widening direction Dw, and the other side insert 602c is disposed on the other side of the protrusion 35 in the arm end widening direction Dw.

[0243] Furthermore, the threaded hole 601a on one side of the screw 381 is not formed directly in the joint 601 on one side, but is formed in the insert 601c on one side. Similarly, the threaded hole 602a on the other side of the screw 382 is not formed directly in the joint 602 on the other side, but is formed in the insert 602c on the other side.

[0244] (1) Thus, the anti-detachment part 60 and the pedal pad 30 are joined together by threading the pedal pad 30 to the inserts 601c and 602c on one side and the other side of the anti-detachment part 60, respectively. Therefore, the arm 40 and the anti-detachment part 60 can be assembled to the pedal pad 30 in a simple way.

[0245] Furthermore, according to this embodiment, threaded holes 601a and 602a are formed in metal inserts 601c and 602c, respectively. Therefore, compared with the case where the threaded holes 601a and 602a are formed in resin portions, the durability of the anti-detachment part 60 can be improved.

[0246] Apart from the above description, this embodiment is the same as the eleventh embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the eleventh embodiment can be obtained.

[0247] <Eighteenth Implementation Method>

[0248] Next, the eighteenth embodiment will be described. In this embodiment, the differences from the aforementioned fourth embodiment will be mainly explained.

[0249] like Figure 32As shown, in this embodiment, the pedal pad 30 and the anti-slip part 56 are joined by a snap-fit ​​structure instead of pressing in the bosses 565a and 565b. That is, the pedal pad 30 and the anti-slip part 56 are joined together by a snap-fit ​​structure.

[0250] Specifically, in this embodiment, the anti-detachment part 56 has a one-side retaining portion 566a and a other-side retaining portion 566b protruding from the base 561 toward the pedal pad 30 side. The one-side retaining portion 566a and the other-side retaining portion 566b constitute a snap-fit ​​structure.

[0251] For example, the anti-detachment part 56 can be made of any elastic material that enables the snap-fit ​​structure to function, such as metal or resin. In this embodiment, it is made of elastic resin. Therefore, the one-sided retaining part 566a and the other-sided retaining part 566b are also made of resin.

[0252] One-sided retaining portion 566a is disposed on one side of the arm end widening direction Dw relative to the protrusion 563, and extends from the base 561 to the opposite side across the pedal pad 30, passing through the arm end widening direction Dw relative to the pedal pad 30. In addition, the front end portion of the one-sided retaining portion 566a has a claw portion 566c protruding to the other side of the arm end widening direction Dw.

[0253] The other retaining portion 566b is disposed on the opposite side of the arm end widening direction Dw relative to the protrusion 563, and extends from the base 561 to the opposite side across the pedal pad 30, passing through the other side of the arm end widening direction Dw relative to the pedal pad 30. In addition, the other retaining portion 566b has a claw portion 566d protruding toward one side of the arm end widening direction Dw at its front end portion.

[0254] The claw portion 566c of one side retaining portion 566a and the claw portion 566d of the other side retaining portion 566b engage with the pedal pad 30 on the pedal surface 301, respectively.

[0255] (1) As described above, according to this embodiment, the pedal pad 30 and the anti-detachment part 56 are connected to each other by a snap-fit ​​structure, so the arm 40 and the anti-detachment part 56 can be assembled to the pedal pad 30 in a simple way.

[0256] Apart from the above description, this embodiment is the same as the fourth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fourth embodiment can be obtained.

[0257] <Nineteenth Implementation Method>

[0258] Next, the nineteenth embodiment will be described. In this embodiment, the differences from the fifth embodiment described above will be mainly explained.

[0259] like Figure 33 As shown, in this embodiment, the pedal pad 30 and the anti-slip part 60 are joined using the same snap-fit ​​structure as in the eighteenth embodiment, instead of the pressing in of the bosses 603a and 603b. That is, the pedal pad 30 and the anti-slip part 60 are joined together by the snap-fit ​​structure.

[0260] Specifically, in this embodiment, the anti-detachment part 60 has a one-side retaining portion 604a protruding from a one-side engaging portion 601 toward the pedal pad 30 side and a other-side retaining portion 604b protruding from a other-side engaging portion 602 toward the pedal pad 30 side. The one-side retaining portion 604a and the other-side retaining portion 604b constitute the same snap-fit ​​structure as in the eighteenth embodiment.

[0261] For example, the anti-detachment part 60 of this embodiment can be made of either metal or resin, just like the anti-detachment part 56 of the eighteenth embodiment. In this embodiment, it is made of elastic resin. Therefore, the one-side retaining part 604a and the other-side retaining part 604b are also made of resin.

[0262] One-sided retaining portion 604a is disposed on one side of the arm end widening direction Dw relative to the protrusion 35, and extends from one-sided engaging portion 601 to the opposite side across the pedal pad 30, passing through the arm end widening direction Dw relative to the pedal pad 30. In addition, the front end portion of the one-sided retaining portion 604a has a claw portion 604c protruding to the other side of the arm end widening direction Dw.

[0263] The other retaining portion 604b is disposed on the other side of the arm end widening direction Dw relative to the protrusion 35, and extends to the opposite side of the pedal pad 30 via the other engaging portion 602. Furthermore, the other retaining portion 604b has a claw portion 604d protruding towards one side of the arm end widening direction Dw at its front end.

[0264] The claw portion 604c of one side retaining part 604a and the claw portion 604d of the other side retaining part 604b engage with the pedal pad 30 on the back 302 of the pedal.

[0265] (1) As described above, according to this embodiment, the anti-detachment part 60 and the pedal pad 30 are connected to each other by the same snap-fit ​​structure as in the eighteenth embodiment. Therefore, the same effect based on this snap-fit ​​structure can be obtained as in the eighteenth embodiment.

[0266] Apart from the above description, this embodiment is the same as the fifth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the fifth embodiment can be obtained.

[0267] <Twentieth Implementation Method>

[0268] Next, the twentieth embodiment will be described. In this embodiment, the differences from the aforementioned eighteenth embodiment will be mainly explained.

[0269] like Figure 34 As shown, in this embodiment, the pedal pad 30 and the anti-slip part 56 are also connected to each other by a snap-fit ​​structure in the same way as in the eighteenth embodiment.

[0270] However, in this embodiment, the one-sided retaining portion 566a does not pass through the side of the arm-end widening direction Dw relative to the pedal pad 30, but rather passes through the through hole 30n provided in the pedal pad 30, extending from the base 561 to the opposite side across the pedal pad 30. Furthermore, the claw portion 566c provided at the front end of the one-sided retaining portion 566a protrudes towards the side of the arm-end widening direction Dw, rather than towards the other side of the arm-end widening direction Dw.

[0271] The other retaining portion 566b is the same. That is, the other retaining portion 566b does not pass through the other side of the arm end widening direction Dw relative to the pedal pad 30, but passes through the through hole 30o provided in the pedal pad 30, extending from the base 561 to the opposite side across the pedal pad 30. Moreover, the claw portion 566d provided at the front end portion of the other retaining portion 566b protrudes to the other side of the arm end widening direction Dw, rather than protruding to one side of the arm end widening direction Dw.

[0272] Apart from the above description, this embodiment is the same as the eighteenth embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the eighteenth embodiment can be obtained as in the eighteenth embodiment.

[0273] <Implementation Method 21>

[0274] Next, the twenty-first embodiment will be described. In this embodiment, the differences from the nineteenth embodiment described above will be mainly explained.

[0275] like Figure 35 As shown, in this embodiment, the pedal pad 30 and the anti-slip part 60 are also connected to each other by a snap-fit ​​structure, just like in the nineteenth embodiment.

[0276] However, in this embodiment, the one-sided retaining portion 604a does not pass through the side of the arm-end widening direction Dw relative to the pedal pad 30, but rather passes through the through hole 30n provided in the pedal pad 30, extending from the one-sided joining portion 601 to the opposite side across the pedal pad 30. Furthermore, the claw portion 604c provided at the front end portion of the one-sided retaining portion 604a protrudes towards the side of the arm-end widening direction Dw, rather than towards the other side of the arm-end widening direction Dw.

[0277] The other retaining portion 604b is the same. That is, the other retaining portion 604b does not pass through the other side of the arm end widening direction Dw relative to the pedal pad 30, but passes through the through hole 30o provided in the pedal pad 30, extending from the other engaging portion 602 to the opposite side across the pedal pad 30. Moreover, the claw portion 604d provided at the front end portion of the other retaining portion 604b protrudes to the other side of the arm end widening direction Dw, rather than protruding to one side of the arm end widening direction Dw.

[0278] Apart from the above description, this embodiment is the same as the nineteenth embodiment. Moreover, in this embodiment, the effects achieved by the same structure as the nineteenth embodiment can be obtained.

[0279] <Twenty-second Implementation>

[0280] Next, the twenty-second embodiment will be described. In this embodiment, the differences from the first embodiment described above will be mainly explained.

[0281] like Figures 36-38 As shown, in this embodiment, the arm end 401 is formed in the same way as in the first embodiment, widening from the arm body 403 to both sides in the arm end widening direction Dw.

[0282] However, unlike the first embodiment, the arm end 401 in this embodiment is formed into a spherical shape. Therefore, in this embodiment, as... Figure 36 As shown, from a perspective along the direction of the arm's widening direction Dw (e.g., along...), Figure 4 From the perspective of the direction of arrow V, one end of the arm 401 also forms a circular shape.

[0283] Apart from the above description, this embodiment is the same as the first embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the first embodiment can be obtained as in the first embodiment.

[0284] Furthermore, this embodiment is a variation of the first embodiment, but it can also be combined with any of the aforementioned second to twenty-first embodiments.

[0285] <Twenty-third Implementation Method>

[0286] Next, the twenty-third embodiment will be described. In this embodiment, the differences from the first embodiment described above will be mainly explained.

[0287] The anti-detachment part 56 in this embodiment is made of resin. Furthermore, the dimensional relationship between the arm 40 and the anti-detachment part 56 is as follows.

[0288] That is, in Figure 39 In the state shown, i.e. the one-sided offset state, the other end 401b of the arm end 401 in the widening direction is located on the other side of the arm end widening direction Dw, which is closer to the insertion hole 564a, and the following equations F1 and F2 are true.

[0289] L1 < 2 × X1 …… (Equation F1)

[0290] L1 < 2 × Y1 …… (Equation F2)

[0291] In this embodiment, the aforementioned lateral offset state refers to the state in which the arm 40 is offset to one side in the arm end widening direction Dw and abuts against the anti-detachment part 56 in the arm end widening direction Dw. In other words, the lateral offset state refers to the state in which there is no gap Ca between the widening end 401a of the arm end 401 and the inner wall surface of the protrusion 563 opposite to the widening end 401a, or the gap Cb between the arm body part 403 and the side receiving part 564b of the first placement part 564. Figure 39 This indicates the state where there is no gap Ca in gap Ca or Cb.

[0292] In Equations F1 and F2 above, L1 is the interval along the normal direction Dv of the base surface 561b, and is the interval between the portion of the other side of the receiving surface 564e of the anti-detachment part 56 located on the reverse operation side along the normal direction Dv of the base surface 561b and the base surface 561b. This interval L1 is, for example, referred to as the first normal direction interval L1. X1 is the width in the arm end widening direction Dw from the other end 401b of the arm end 401 to the insertion hole 564a. In addition, Y1 is the width of the other side receiving surface 564e in the arm end widening direction Dw. Furthermore, as Figure 39 As shown, the widths X1 and Y1 are related as “Y1≥X1”. Therefore, if the above equation F1 holds, then the above equation F2 also holds.

[0293] In addition, Figure 40The state shown is the same as the one-sided offset state described above. That is, in the other-sided offset state, the widening direction end 401a of one end of the arm 401 is located on the side of the arm end widening direction Dw that is closer to the insertion hole 564a, and the following equations F3 and F4 are true.

[0294] L2<2×X2……(Equation F3)

[0295] L2 < 2 × Y2……(Equation F4)

[0296] In this embodiment, the aforementioned "other side offset state" refers to the state in which the arm 40 is offset to the other side of the arm end widening direction Dw and abuts against the anti-detachment part 56 in the arm end widening direction Dw. In other words, the "other side offset state" refers to the state in which there is no gap Cc between the other end 401b of the arm end 401 in the widening direction and the inner wall surface of the protrusion 563 opposite to the other end 401b in the widening direction, or no gap Cd between the arm body part 403 and the other side receiving part 564c of the first placement part 564. Figure 40 This indicates the state where gap Cc is absent from gaps Cc and Cd.

[0297] In equations F3 and F4 above, L2 is the interval along the normal direction Dv of the base surface 561b, and is the interval between the portion of the anti-detachment part 564d on one side of the receiving surface 564d located on the reverse operation side of the base surface 561b along the normal direction Dv of the base surface 561b and the base surface 561b. This interval L2 is, for example, referred to as the second normal direction interval L2. X2 is the width in the arm end widening direction Dw from the widening end 401a of the arm end 401 to the insertion hole 564a. In addition, Y2 is the width of the one side receiving surface 564d in the arm end widening direction Dw. Furthermore, as Figure 40 As shown, width X2 and width Y2 are related by the condition "Y2 ≥ X2". Therefore, if equation F3 is true, then equation F4 is also true. Furthermore, in this embodiment, for example, the second normal direction spacing L2 is the same size as the first normal direction spacing L1.

[0298] (1) Here, we assume, for example, a detachable structure that allows one component to be detached from another component through elastic deformation, such as a snap-fit ​​structure. In this detachable structure, generally speaking, the length L3 corresponding to the above-mentioned normal direction intervals L1 and L2 and the width X3 corresponding to the above-mentioned widths X1 and X2 are related by the following formula F5. Moreover, the length L3 and the width Y3 corresponding to the above-mentioned widths Y1 and Y2 are related by the following formula F6.

[0299] L3≥2×X3……(Equation F5)

[0300] L3≥2×Y3……(Equation F6)

[0301] In contrast, according to this embodiment, equation F1 holds true when the arm is offset to one side, and equation F3 holds true when the arm is offset to the other side. Therefore, the structure of the anti-detachment part 56 holding one end of the arm 401 in the receiving space 563a is not a detachable structure like the one in the comparative example described above. That is, it can prevent one end of the arm 401 from detaching from the receiving space 563a due to the elastic deformation of one side receiving portion 564b or the other side receiving portion 564c of the first placement portion 564, thereby improving the reliability of the pedal device 1.

[0302] Apart from the above description, this embodiment is the same as the first embodiment. Moreover, in this embodiment, the same effects achieved by the structure common to the first embodiment can be obtained as in the first embodiment.

[0303] Furthermore, this embodiment is a variation of the first embodiment, but it can be combined as long as the embodiments described above use resin to form the protrusions 35, 563 of the receiving arm end 401.

[0304] Furthermore, assuming, for example, that resin is used to construct the protrusion 35 (see reference). Figure 14 When the modified example of the third embodiment is used as a modification of the present embodiment, the modified example of the third embodiment can be combined with the present embodiment. In this case, in the lateral offset state, the arm 40 abuts against the pedal pad 30 (see reference) in the arm end widening direction Dw. Figure 14 Instead of the anti-slip part 56, the arm 40 abuts against the pedal pad 30 in the arm end widening direction Dw, and not the anti-slip part 56, when it is in the offset state on the other side.

[0305] <Other Implementation Methods>

[0306] (1) In the above embodiments, the pedal device 1 is used as a brake pedal device, but this is only one example. For example, the pedal device 1 can also be used as an accelerator pedal device operated for adjusting the output of the drive source of the vehicle 80.

[0307] (2) In the above embodiments, the pedal device 1 is a brake pedal device for a brake-by-wire system, but it is only one example. For example, it may also be structured as follows: in a vehicle 80 in which the pedal device 1 is provided, a brake-by-wire system is not used, and the pedal device 1 mechanically connects the pedal pad 30 to the master cylinder constituting the braking system.

[0308] (3) In the above embodiments, such as Figure 3 As shown, the reaction force generating mechanism 50 has multiple spring components 511, 512, and 513, but the reaction force generating mechanism 50 may also have only one spring component.

[0309] Furthermore, the reaction force generating mechanism 50 can also generate a reaction force relative to the pedaling force through mechanical structures other than spring components 511, 512, and 513. For example, in a vehicle 80 that does not employ a brake-by-wire system, a mechanical structure including a hydraulic cylinder for generating hydraulic pressure for driving the brake pads corresponds to the reaction force generating mechanism 50.

[0310] (4) In the above embodiments, for example, Figure 5 As shown, the arm body 403 is formed in a straight-line extending shape, but this is only one example. For example, the arm body 403 may also be formed in a curved extending shape.

[0311] (5) In the above embodiments, for example, Figure 13 As shown, pedal device 1 is an organ-type pedal device, but it can also be a pedal device other than organ-type.

[0312] For example, in various embodiments, the pedal device 1 is accordion-type, so the pedal axis CL is positioned closer to the lower end 304 of the pedal pad 30 than to the upper end 303 of the pedal pad 30. In contrast, as an example of a pedal device other than accordion-type, a structure can also be conceived where the pedal axis CL is positioned closer to the upper end 303 than to the lower end 304 of the pedal pad 30. In such a structure, for example, the arm 40 is positioned below the vehicle relative to the pedal axis CL located near the upper end 303 of the pedal pad 30. Furthermore, the pedal pad 30 rotates in such a manner that the lower end 304 of the pedal pad 30 moves further downwards or forwards from the vehicle as the driving force 81 applied to the pedal pad 30 from the operating side increases.

[0313] (6) In the first embodiment described above, as Figure 3 and Figure 4 As shown, one end 401 of the arm is shaped to widen from the main body 403 towards the arm end in a widening direction Dw, which is along the direction of the pedal axis CL, but this is just one example. For example, if in Figure 3 The upper arm 40 of the cross section can be oscillatingly connected to the pedal pad 30, and one end 401 of the arm can also be formed into a shape that widens from the main body 403 of the arm in the direction of intersecting with the pedal axis CL.

[0314] (7) In the twenty-third embodiment described above, Figure 39 Under the shown one-sided offset state, the above equation F1 holds, and, in Figure 40In the other side offset state shown, the above equation F3 holds true. The limitation of L1 and L2 can be as described, but a more preferred solution will be described. For example, the protrusion 563 can also be configured such that the relationship "L1 < X1 / 2" holds true in the one side offset state, and the relationship "L2 < X2 / 2" holds true in the other side offset state.

[0315] (8) Furthermore, this disclosure is not limited to the above-described embodiments and can be implemented in various modifications. In addition, the above-described embodiments are not mutually exclusive and can be appropriately combined except in cases where they are obviously incompatible.

[0316] Furthermore, in the above embodiments, the elements constituting the embodiment are not necessarily essential, except where they are specifically stated to be necessary or where they are clearly considered necessary in principle. Also, in the above embodiments, when referring to the number, value, quantity, range, or other numerical values ​​of the constituent elements of the embodiment, they are not limited to that specific number, except where they are specifically stated to be necessary or where they are clearly limited to a specific number in principle.

[0317] Furthermore, in the above embodiments, when referring to the material, shape, positional relationship, etc. of the constituent elements, they are not limited to that material, shape, positional relationship, etc., except as specifically stated or as limited in principle to a specific material, shape, positional relationship, etc.
