[0008] Patent Document 1: Japanese Patent No. 5491115 Summary of the invention

[0009] However, in the reaction force imparting device such as Patent Document 1, the rotating part is usually made of a molded product such as resin, and has concave-convex parts such as gate marks and parting step surfaces formed on the surface during molding. Therefore, in the reaction force imparting device of Patent Document 1, if the above-mentioned concave-convex parts are formed at the position of the rotating part that abuts against the arm, when the driver performs a pedaling operation, the above-mentioned concave-convex parts abut against the arm, which may cause vibration. As a result, the vibration is transmitted to the driver via the arm and the pedal, and the driver's pedaling feeling may be deteriorated.

[0010] An object of the present disclosure is to provide a reaction force applying device capable of suppressing the vibration of a generated component.

[0011] The present invention discloses a reaction force imparting device, which can impart a reaction force to a pedal of an accelerator device having a pedal that is stepped on by a driver, with respect to the pedaling force of the driver, and comprises an actuator, a connecting rod and an abutting member. The actuator generates a driving force by energizing. The connecting rod rotates by the driving force from the actuator, and can impart the reaction force to the pedal or an arm that rotates with the pedal.

[0012] The contact component is provided on the connecting rod in a manner that it can contact with the pedal or the arm or can be separated from the pedal or the arm. The contact component is formed of resin and has a contact component body, a contact surface formed on the contact component body and capable of contacting with the pedal or the arm, and a convex or concave specific shape portion formed on the contact component body during molding.

[0013] The specific shape portion is formed at a position other than the abutting surface portion in the abutting member body. Therefore, when the driver performs a stepping operation, the specific shape portion does not abut against the pedal or the arm, and the generation of vibration can be suppressed.

[0042] Hereinafter, a reaction force applying device according to a plurality of embodiments and an accelerator device to which the reaction force applying device is applied will be described based on the drawings. In addition, in a plurality of embodiments, substantially the same components are denoted by the same reference numerals and description thereof is omitted.

[0043] (First Embodiment)

[0044] Figure 1 , Figure 2 A reaction force applying device according to a first embodiment and an accelerator device to which the reaction force applying device is applied are shown.

[0045] The accelerator device 60 is mounted on the vehicle 1, and detects the accelerator opening corresponding to the rotation angle of the pedal 70 stepped on by the driver, and is used to control the driving state of the vehicle 1. The accelerator device 60 adopts a wire-controlled accelerator method and is not mechanically connected to the throttle device of the vehicle 1. The accelerator device 60 transmits information related to the accelerator opening corresponding to the rotation angle of the pedal 70 to an electronic control unit (hereinafter referred to as "ECU") not shown in the figure. The ECU controls the throttle device based on the accelerator opening transmitted from the accelerator device 60. In this way, the driving state of the vehicle 1 is controlled.

[0046] The reaction force applying device 10 is mounted on the vehicle 1 together with the accelerator device 60, and can apply a reaction force F2 to the pedal 70 of the accelerator device 60 with respect to the driver's pedal force F1. The reaction force applying device 10 can provide driver notifications such as danger notifications and fuel economy improvement notifications to the driver by applying a reaction force to the pedal 70 of the accelerator device 60. In addition, the reaction force applying device 10 can make the pedal 70 serve as a footrest by limiting the rotation of the pedal 70.

[0047] exist Figure 1In the figure, the x-axis indicates the traveling direction of the vehicle 1, the y-axis indicates the vehicle width direction, and the z-axis indicates the vertical upward direction. In the following, unless otherwise specified, the shape or structure of the accelerator device 60 and the reaction force imparting device 10 installed in the vehicle 1 is described. For example, "above" or "upper side" refers to the upper side or upper side of the accelerator device 60 or the reaction force imparting device 10 installed in the vehicle 1. In addition, in the present embodiment, the vehicle floor 2 has a wall surface 7 parallel to the yz plane and a wall surface 8 inclined relative to the wall surface 7.

[0048] The accelerator device 60 includes a pedal housing 61, a pedal 70, etc. The pedal housing 61 is fixed to a wall surface 8 of the vehicle floor 2 of the vehicle 1 by, for example, mounting bolts (not shown), thereby being mounted to the vehicle floor 2.

[0049] The pedal 70 is rotatably supported on the pedal housing 61 so as to rotate around the rotation axis Ax1. The pedal 70 is provided with a pedal pad 71 stepped on by the driver. An accelerator opening sensor (not shown) is provided in the pedal housing 61. The accelerator opening sensor detects the accelerator opening corresponding to the rotation angle of the pedal 70 rotated by the driver's stepping operation, and transmits it to the ECU. In addition, the rotation axis Ax1 is set to be orthogonal to the z-axis and the x-axis and parallel to the y-axis.

[0050] A pedal force member (not shown) is provided in the pedal housing 61. The pedal 70 is forced in the accelerator closing direction by the pedal force member. The pedal housing 61 has a stopper for limiting the rotation of the pedal 70 in the accelerator closing direction and a stopper for limiting the rotation of the pedal 70 in the accelerator opening direction. The pedal 70 can rotate within the range of contact with the two stoppers. Figure 1 This shows a state where the pedal 70 is in contact with a stopper in the accelerator closing direction, that is, a state where the accelerator is fully closed.

[0051] like Figure 1 to Figure 3 As shown, the reaction force applying device 10 includes an actuator 20, a link 40, and a contact member 50. The actuator 20 generates a driving force by energizing. The link 40 rotates by the driving force from the actuator 20, and can apply a reaction force to the pedal 70 against the driver's stepping force.

[0052] The contact member 50 is provided on the link 40 so as to be able to contact with or be separated from the pedal 70. The contact member 50 is formed of resin and includes a contact member body 51, a contact surface 52 formed on the contact member body 51 and able to contact with the pedal 70, and a convex or concave specific shape portion 53 formed on the contact member body 51 during molding. The specific shape portion 53 is formed at a position other than the contact surface 52 in the contact member body 51.

[0053] More specifically, the reaction force applying device 10 includes an actuator housing 11. The actuator housing 11 is attached to the vehicle floor panel 2 of the vehicle 1 by being fixed to the wall surface 7 of the vehicle floor panel 2 by mounting bolts (not shown), for example.

[0054] The actuator 20 is, for example, an electric motor, and is housed in the actuator housing 11. The actuator 20 can output torque as a driving force by being energized. The ECU controls the energization of the actuator 20 and can control the operation of the actuator 20. A speed reducer composed of a plurality of gears not shown is provided in the actuator housing 11. The speed reducer can reduce the torque of the actuator 20 and output it from the shaft member 36. The shaft member 36 is provided on the rotation axis Ax2 and is supported by the actuator housing 11 in a manner that allows rotation around the rotation axis Ax2.

[0055] The connecting rod 40 includes a connecting rod body 41, a connecting rod one end 42, a connecting rod other end 43, etc. The connecting rod body 41 is formed into a rod shape, for example, by metal, etc. The connecting rod one end 42 is connected to one end of the connecting rod body 41 and is formed integrally with the connecting rod body 41. The connecting rod other end 43 is connected to the other end of the connecting rod body 41 and is formed integrally with the connecting rod body 41. The connecting rod other end 43 is formed to be substantially at a right angle to the connecting rod body 41. The connecting rod other end 43 is arranged in a manner parallel to the y-axis.

[0056] The connecting rod 40 is provided so that the connecting rod one end portion 42 is connected to the shaft member 36. Thus, the connecting rod 40 is rotatably supported by the actuator housing 11 so as to rotate around the rotation axis Ax2 together with the shaft member 36. The connecting rod 40 rotates around the rotation axis Ax2 by the driving force from the actuator 20 output from the shaft member 36.

[0057] like Figure 1 As shown, the reaction force applying device 10 is provided so that the outer peripheral wall of the contact member 50 can contact with the surface of the pedal 70 of the accelerator device 60 on the vehicle floor 2 side and can be separated from the surface of the pedal 70 on the vehicle floor 2 side. Thus, the reaction force applying device 10 can apply the reaction force F2 to the driver's stepping force F1 to the pedal 70 via the contact member 50 from the link 40 rotated by the driving force from the actuator 20.

[0058] Next, the contact member 50 will be described in more detail.

[0059] like Figure 3 to Figure 5 As shown, the contact member 50 also has a sliding surface 54 which is rotatable relative to the connecting rod 40 and formed on the contact member body 51 and can slide with other members. The specific shape portion 53 is formed at a position other than the sliding surface 54 in the contact member body 51.

[0060] More specifically, the contact member 50 includes a member recess 551, a member recess 552, a member recess 553, and a member recess 554. The contact member body 51 is formed in a substantially cylindrical shape. The member recess 551 is formed in an annular shape in an axially recessed manner from the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Figure 3 , Figure 4 The member recess 552 is formed in an annular shape so as to be recessed in the axial direction from the end surface of the member body 51 on the connecting rod body 41 side that contacts the member body 51 (see Figure 3 , Figure 5 The member recess 553 is formed in an annular shape so as to be recessed in the axial direction from the outer edge of the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Figure 3 , Figure 4 The member recess 554 is formed in an annular shape so as to be recessed in the axial direction from the inner edge of the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Figure 3 , Figure 4 ). In addition, the outer edge and inner edge of the end surface of the contact member body 51 on the connecting rod body 41 side are chamfered (see Figure 3 , Figure 5 ).

[0061] The specific shape portion 531 is a convex gate mark formed on the contact component body 51 during molding, and is formed on the bottom surface of the component recess 551 (see Figure 3 , Figure 4 The specific shape portion 532 is an annular and convex ejector pin mark formed on the contact component body 51 during molding, and is formed on the bottom surface of the component recess 552 (see Figure 3 , Figure 5 ). Three specific shape portions 532 are formed at equal intervals in the circumferential direction of the component recess 552 (see Figure 5 The specific shape portion 533 is an annular and convex burr formed on the contact component body 51 during molding, and is formed in a manner protruding from the outer edge of the component recess 553 to the side opposite to the connecting rod body 41 (see Figure 3 , Figure 4 The specific shape portion 534 is an annular and convex burr formed on the contact member body 51 during molding, and is formed in a manner protruding from the inner edge of the member recess 554 to the side opposite to the connecting rod body 41 (see Figure 3 , Figure 4 ).

[0062] The inner diameter of the contact member body 51 is larger than the outer diameter of the connecting rod other end portion 43. Therefore, the contact member 50 is relatively rotatable with respect to the connecting rod other end portion 43 and is relatively movable in the axial direction.

[0063] The connecting rod 40 has an anti-slip portion 46. The anti-slip portion 46 is formed of, for example, a metal in an annular plate shape. An engaging groove portion 431 is formed at the connecting rod other end portion 43. The engaging groove portion 431 is formed in an annular shape in a manner that is recessed radially inward from the outer peripheral wall of the end portion of the connecting rod other end portion 43 on the side opposite to the connecting rod body 41 relative to the abutment member 50.

[0064] The anti-dropout portion 46 is provided on the link other end portion 43 so that the inner edge portion thereof is fitted into and engaged with the engagement groove portion 431. Thus, it is possible to restrict the contact member 50 from dropping out from the link other end portion 43.

[0065] In the present embodiment, the contact surface portion 52 that can contact the pedal 70 is formed at all locations of the outer peripheral wall of the contact member main body 51 (see Figure 3 , Figure 4 The sliding surface portion 541 that can slide with the anti-detachment portion 46 as another component is formed in an annular shape on the radially outer side and the radially inner side of the component recess 551 (see Figure 4 The sliding surface portion 542 that can slide with the connecting rod body 41 of the connecting rod 40 as another component is formed in an annular shape on the radially outer side and the radially inner side of the component recess 552 (see Figure 3 , Figure 5 ). In addition, the contact surface portion 52, the sliding surface portion 541, and the sliding surface portion 542 are formed in the portions shown by hatching in the drawings (the same applies hereinafter).

[0066] In this way, the specific shape portion 53 is formed at a position other than the contact surface portion 52 and other than the sliding surface portions 541 and 542 in the contact member main body 51 .

[0067] In this embodiment, the depth d1 of the component recess 551 is greater than the protruding height of the specific shape portion 531. The depth d2 of the component recess 552 is greater than the protruding height of the specific shape portion 532. The depths d3 of the component recesses 553 and 554 are greater than the protruding heights of the specific shape portions 533 and 534 (see Figure 3 Therefore, when the contact member 50 rotates, the specific shape portions 531 , 533 , and 534 are prevented from contacting the anti-detachment portion 46 , and the specific shape portion 532 is prevented from contacting the link body 41 .

[0068] Next, based on Figure 6 The molding process of the contact member 50 will be described.

[0069] First, the movable main mold 140 is fitted with the fixed main mold 130, and a cavity 150 corresponding to the shape of the contact member 50 is formed between the fixed main mold 130 and the movable main mold 140. Next, the molten resin is filled into the cavity 150 from the gate 141 formed in the movable main mold 140. After the resin filled into the cavity 150 is cooled and solidified, the movable main mold 140 is moved to the opposite side of the fixed main mold 130. Next, the ejector pin 131 provided in the fixed main mold 130 is pushed to push the contact member 50 out of the fixed main mold 130. Thus, the molding of the contact member 50 is completed.

[0070] Next, a process of forming the specific shape portion 53 when molding the contact member 50 will be described.

[0071] When the movable main mold 140 is moved to the opposite side of the fixed main mold 130 while the resin filled in the cavity 150 is cooled and solidified, the resin remaining in the gate 141 is torn off, forming a specific shape portion 531 as a convex gate mark.

[0072] When the fixed main mold 130 and the movable main mold 140 are fitted together, an annular mold gap 151 is formed at the outer edge of the surface of the movable main mold 140 side of the cylindrical cavity 150, and an annular mold gap 152 is formed at the inner edge. Therefore, when the contact member 50 is molded, if part of the resin filled in the cavity 150 enters the mold gaps 151 and 152 and is cooled and solidified, annular and convex burrs, namely, specific shape parts 533 and 534 are formed.

[0073] When the ejector pin 131 is provided in the pin hole 132 of the fixed main mold 130, an annular pin-mold gap 153 is formed between the pin hole 132 on the surface of the cavity 150 opposite to the movable main mold 140 and the ejector pin 131. Therefore, when the contact member 50 is molded, if a part of the resin filled in the cavity 150 enters the pin-mold gap 153 and is cooled and solidified, an annular and convex ejector pin mark, i.e., a specific shape portion 532 is formed.

[0074] As described above, in the present embodiment, the contact member 50 is formed of resin and includes the contact member body 51, the contact surface portion 52 formed on the contact member body 51 and capable of contacting the pedal 70, and the convex or concave specific shape portion 53 formed on the contact member body 51 during molding. The specific shape portion 53 is formed at a position other than the contact surface portion 52 in the contact member body 51.

[0075] The specific shape portion 53 is formed at a position other than the abutting surface portion 52 in the abutting member body 51. Therefore, when the driver performs a stepping operation, the specific shape portion 53 does not abut against the pedal 70, and the generation of vibration can be suppressed. Thus, the vibration can be suppressed from being transmitted to the driver via the pedal 70, which causes the driver's pedaling feeling to deteriorate.

[0076] In addition, in the present embodiment, the contact member 50 further includes a sliding surface 54 which is rotatable relative to the connecting rod 40 and is formed on the contact member body 51 and is slidable with other members. The specific shape portion 53 is formed at a position other than the sliding surface 54 in the contact member body 51.

[0077] Therefore, when the contact member 50 rotates, the specific shape portion 53 can be prevented from contacting other members, and the generation of vibration can be suppressed. Thus, the vibration can be prevented from being transmitted to the driver via other members and the pedal 70, thereby preventing the driver's pedaling feeling from being deteriorated.

[0078] (Second Embodiment)

[0079] A reaction force imparting device according to a second embodiment and an accelerator device using the reaction force imparting device are as follows Figure 7 , Figure 8 The structures of the reaction force applying device 10 and the accelerator device 60 of the second embodiment are different from those of the first embodiment.

[0080] In the present embodiment, the pedal housing 61 of the accelerator device 60 is fixed to the wall surface 7 of the vehicle floor panel 2 of the vehicle 1 by, for example, mounting bolts (not shown) and thus mounted to the vehicle floor panel 2 .

[0081] The pedal 70 includes a pedal pad 71, a pedal base 72, and a pedal connection portion 73. The pedal connection portion 73 is formed of, for example, metal, and connects the pedal pad 71 to the pedal base 72 in a manner that one end is connected to the pedal pad 71 and the other end is connected to the pedal base 72. The pedal base 72 is rotatably supported by the pedal housing 61 so as to rotate around the rotation axis Ax1. Thus, the pedal 70 can rotate around the rotation axis Ax1.

[0082] In the present embodiment, the accelerator device 60 further includes an arm 80. The arm 80 is formed by, for example, bending a long plate-shaped member made of metal at a predetermined position (see Figure 8 The arm 80 is attached to the pedal 70 in a manner such that one end portion is connected to the pedal base 72. Thus, the arm 80 can rotate around the rotation axis Ax1 together with the pedal 70.

[0083] In the present embodiment, the actuator housing 11 of the reaction force applying device 10 is fixed to a pedestal 9 provided on the wall surface 7 of the vehicle floor 2 of the vehicle 1 by, for example, mounting bolts (not shown), and is thereby mounted to the vehicle floor 2 via the pedestal 9 .

[0084] In the present embodiment, the reaction force applying device 10 has a shorter link body 41 of a link 40 than that of the first embodiment.

[0085] like Figure 7 As shown, the reaction force applying device 10 is provided so that the outer peripheral wall of the contact member 50 can contact with the surface of the arm 80 of the accelerator device 60 on the side opposite to the vehicle floor 2, and can be separated from the surface of the arm 80 on the side opposite to the vehicle floor 2. Thus, the reaction force applying device 10 can apply the reaction force F2 to the driver's stepping force F1 to the pedal 70 from the link 40 rotated by the driving force from the actuator 20 via the contact member 50 and the arm 80.

[0086] This embodiment is the same as the first embodiment except for the above-mentioned structure. Therefore, the same structure as the first embodiment can achieve the same function and effect as the first embodiment (the same below).

[0087] (Third Embodiment)

[0088] exist Figures 9-11 A part of the reaction force applying device of the third embodiment is shown in FIG. The structure of the contact member 50 of the third embodiment is different from that of the first embodiment.

[0089] In this embodiment, the contact member body 51 includes a main body shaft portion 56 and a main body flange portion 57. The main body shaft portion 56 is formed in a substantially cylindrical shape. The main body flange portion 57 is formed integrally with the main body shaft portion 56 in a manner extending annularly from the end of the main body shaft portion 56 on the side of the anti-detachment portion 46 to the radially outer side.

[0090] The specific shape portion 531 is a convex gate mark formed on the contact component body 51 during molding, and is formed on the outer edge of the end surface of the main body flange portion 57 on the side of the anti-detachment portion 46 (see Fig. 9 , Fig.10 The specific shape portion 532 is an annular and convex ejector pin mark formed on the abutment component body 51 during molding, and is formed on the outer edge of the end surface of the main body flange portion 57 on the side of the anti-detachment portion 46 (see Fig. 9 , Fig.10 ). Three specific shape portions 532 are formed at equal intervals in the circumferential direction of the main body flange portion 57 (see Fig.10 The specific shape portion 533 is an annular and convex burr formed on the contact member body 51 during molding, and is formed to protrude radially outward from the end of the main body flange portion 57 on the opposite side of the anti-detachment portion 46 (see Figures 9 to 11 ).

[0091] The specific shape portions 531 and 532 are formed on the radially outer side of the anti-detachment portion 46 (see Fig. 9 ).

[0092] In this embodiment, the contact surface portion 52 that can contact the pedal 70 is formed at all locations of the outer peripheral wall of the main body shaft portion 56 on the side opposite to the anti-detachment portion 46 relative to the main body flange portion 57 (see Fig. 9 , Fig.11 The sliding surface portion 541 that can slide with the anti-detachment portion 46 as another component is formed into an annular shape at the inner edge of the end surface of the main body flange portion 57 on the anti-detachment portion 46 side (see Fig. 9 , Fig.10 The sliding surface portion 542 that can slide with the connecting rod body 41 of the connecting rod 40 as another component is formed in an annular shape on the end surface of the main body shaft portion 56 on the side opposite to the main body flange portion 57 (see Fig. 9 , Fig.11 ).

[0093] In this way, the specific shape portion 53 is formed in a position other than the abutting surface portion 52 and other than the sliding surface portions 541 and the sliding surface portions 542 in the abutting member body 51. Therefore, when the driver performs a stepping operation, the specific shape portion 53 does not abut against the pedal 70, and the generation of vibration can be suppressed. In addition, when the abutting member 50 rotates, etc., the specific shape portion 53 can be suppressed from contacting other components, and the generation of vibration can be suppressed. Thus, as in the first embodiment, it is possible to suppress the situation in which the driver's pedaling force feeling is deteriorated by being transmitted to the driver via the pedal 70.

[0094] (Fourth Embodiment)

[0095] exist Figures 12-14 1 and 2 show a part of the reaction force applying device according to the fourth embodiment. The structure of the contact member 50 according to the fourth embodiment is different from that of the first embodiment.

[0096] In this embodiment, the contact member 50 has a member recess 553, a member recess 554, and a member recess 555. The member recess 553 is formed in an annular shape in an axially recessed manner from the outer edge of the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Fig.12 , Fig.13 The depth of the component recess 553 is deeper than the depth d3 of the component recess 553 of the first embodiment (see Figure 3 , Fig.12). In addition, the inner diameter of the component recess 553 is smaller than the outer diameter of the anti-detachment portion 46. Therefore, the radial width of the component recess 553 is substantially the same as the radial width of the abutment component body 51. The component recess 554 is formed in an annular shape in an axially recessed manner from the inner edge of the end surface of the abutment component body 51 on the opposite side to the connecting rod body 41 (see Fig.12 , Fig.13 The member recess 555 is formed in an annular shape so as to be recessed in the axial direction from the outer edge of the end surface of the member body 51 on the connecting rod body 41 side that contacts the member body 51 (see Fig.12 , Fig.14 The depth of the component recess 555 is greater than the depth d2 of the component recess 552 of the first embodiment (see Figure 3 , Fig.12 ). In addition, the inner diameter of the component recess 555 is substantially the same as the inner diameter of the component recess 553. In addition, the inner edge of the end surface of the connecting rod body 41 side that contacts the component body 51 is chamfered (see Fig.12 , Fig.14 ).

[0097] The specific shape portion 531 is a convex gate mark formed on the contact component body 51 during molding, and is formed on the bottom surface of the component recess 553 (see Fig.12 , Fig.13 The specific shape portion 532 is an annular and convex ejector pin mark formed on the contact component body 51 during molding, and is formed on the bottom surface of the component recess 553 (see Fig.12 , Fig.13 ). Three specific shape portions 532 are formed at equal intervals in the circumferential direction of the component recess 553 (see Fig.12 The specific shape portion 533 is an annular and convex burr formed on the contact component body 51 during molding, and is formed in a manner protruding from the outer edge of the component recess 553 to the side opposite to the connecting rod body 41 (see Fig.12 , Fig.13 ).

[0098] In this embodiment, the contact surface portion 52 that can contact the pedal 70 is formed in all parts between the member recesses 553 and 555 in the outer peripheral wall of the contact member body 51 (see Fig.13 The sliding surface portion 541 that can slide with the anti-detachment portion 46 as another component is formed in an annular shape between the component recessed portion 553 and the component recessed portion 554 (see Fig.12 , Fig.13 The sliding surface portion 542, which is a surface that can slide with the connecting rod body 41 of the connecting rod 40 as another component, is formed in an annular shape on the radial inner side of the component recess 555 (see Fig.12 , Fig.14 ).

[0099] In this way, the specific shape portion 53 is formed at a position other than the contact surface portion 52 and other than the sliding surface portions 541 and 542 in the contact member main body 51 .

[0100] In this embodiment, the areas of the contact surface 52, the sliding surface 541, and the sliding surface 542 are smaller than those in the first embodiment (see Figure 3 to Figure 5 , Figure 12 to Figure 14 ). Therefore, the sliding torque between the contact member 50 and other members can be reduced.

[0101] (Fifth Embodiment)

[0102] exist Figures 15 to 17 1 and 2 show a part of the reaction force applying device according to the fifth embodiment. The structure of the contact member 50 according to the fifth embodiment is different from that of the first embodiment.

[0103] The contact member 50 further includes a fixing portion 58 capable of fixing the contact member body 51 to the link 40. The fixing portion 58 is provided at a position other than the contact surface portion 52 of the contact member 50.

[0104] The specific shape portion 53 is formed at a position that does not come into contact with the fixing portion 58 .

[0105] More specifically, in this embodiment, the fixing portion 58 is provided on the inner peripheral wall of the contact member body 51. The inner diameter of the contact member body 51 is smaller than the outer diameter of the connecting rod other end portion 43. The contact member 50 is fixed by press-fitting or bonding to the connecting rod other end portion 43 so as to be non-rotatable and non-movable in the axial direction.

[0106] In this embodiment, since the contact member 50 is set to be non-rotatable relative to the other end portion 43 of the connecting rod, the contact member 50 is prevented from sliding with the anti-detachment portion 46 as other components and the connecting rod body 41 of the connecting rod 40. Therefore, the sliding surface portion 54 (see FIG. 5 ) as shown in the first embodiment is not formed on the contact member body 51. Figure 15 to Figure 17 ).

[0107] Furthermore, since the contact member 50 is arranged to be non-rotatable relative to the other end portion 43 of the connecting rod, the contact surface portion 52 that can contact the pedal 70 is set within a predetermined range R1 in the circumferential direction of the outer peripheral wall of the contact member body 51 (see Figure 15 to Figure 17 ).

[0108] Furthermore, in the present embodiment, when the driver steps on the pedal 70 , the contact member 50 is slidable relative to the pedal 70 .

[0109] In this way, the specific shape portion 53 is formed at a position other than the abutting surface portion 52 in the abutting member main body 51 and not in contact with the fixing portion 58 .

[0110] As described above, in the present embodiment, the contact member 50 further includes the fixing portion 58 capable of fixing the contact member body 51 to the link 40. The fixing portion 58 is provided at a position other than the contact surface portion 52 of the contact member 50.

[0111] Therefore, when the driver performs a stepping operation, the fixing portion 58 and the pedal 70 do not come into contact with each other, and the generation of vibration can be suppressed. Thus, the vibration can be suppressed from being transmitted to the driver via the pedal 70, thereby suppressing the driver's pedaling feeling from being deteriorated.

[0112] In addition, in the present embodiment, the specific shape portion 53 is formed at a position that does not contact the fixing portion 58 .

[0113] Therefore, the fixed state of the contact member main body 51 and the link 40 by the fixing portion 58 can be stabilized.

[0114] (Sixth Embodiment)

[0115] exist Fig.18 , 19 1 and 2 show a part of the reaction force applying device according to the sixth embodiment. The structure of the contact member 50 according to the sixth embodiment is different from that of the fifth embodiment.

[0116] In this embodiment, the member recess 551 is not formed in an annular shape but is simply recessed in the axial direction from the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Fig.18 ). The specific shape portion 531 is formed on the bottom surface of the component recess 551 .

[0117] In this embodiment, the member recess 552 is not formed in an annular shape but is simply recessed in the axial direction from the end surface of the member body 51 on the connecting rod body 41 side (see Fig.19 ). Three member recesses 552 are formed at equal intervals in the circumferential direction of the contact member body 51. The specific shape portion 532 is formed on the bottom surface of each of the three member recesses 552.

[0118] In this way, the component recesses 551 and 552 can be limitedly provided around the specific shape portions 531 and 532 .

[0119] (Seventh Embodiment)

[0120] exist Figure 20 to Figure 22 1 and 2 show a part of the reaction force applying device according to the seventh embodiment. The structure of the contact member 50 according to the seventh embodiment is different from that of the first embodiment.

[0121] In this embodiment, the contact member 50 does not include the member recesses 551, 552, 553, and 554, but includes the member plane portion 59. The member plane portion 59 is formed in a planar shape so as to be recessed from the outer peripheral wall in a part of the circumferential direction of the contact member body 51.

[0122] The contact component body 51 is provided with a component through hole portion 501 connecting the inner peripheral wall and the component flat surface portion 59. Two component through holes 501 are formed at a predetermined interval in the axial direction of the contact component body 51. A connecting rod hole portion 432 is formed at the connecting rod other end portion 43, which is recessed in the radial direction inward from the outer peripheral wall in a hole shape. Two connecting rod holes 432 are formed at a predetermined interval in the axial direction of the connecting rod other end portion 43, similarly to the component through hole portion 501. In the present embodiment, the anti-detachment portion 46 is not provided.

[0123] In the present embodiment, the fixing portion 58 is, for example, a screw, and has a fixing portion head 581 and a fixing portion shaft 582. The fixing portion head 581 is formed in a substantially disk shape. The fixing portion shaft 582 is formed to extend axially from the center of the fixing portion head 581. The fixing portion 58 is configured such that the fixing portion shaft 582 passes through the component through-hole portion 501 of the abutting component 50 and is screwed into the connecting rod hole portion 432 of the connecting rod other end portion 43. Thus, the abutting component 50 is fixed relative to the connecting rod other end portion 43 so as to be non-rotatable and non-movable in the axial direction.

[0124] The specific shape portion 531 is a convex gate mark formed on the contact member body 51 during molding, and is formed on the end surface of the contact member body 51 on the connecting rod body 41 side (see Fig. 20 , Fig. 22 The specific shape portion 533 is an annular and convex burr formed on the contact member body 51 during molding, and is formed to protrude from the outer edge of the end surface of the contact member body 51 on the connecting rod body 41 side toward the connecting rod body 41 side (refer to Fig. 20 , Fig. 22 ).

[0125] In the present embodiment, since the contact member 50 is provided so as to be immovable relative to the link other end portion 43 in the axial direction, the specific shape portions 531 and 533 do not come into contact with the link body 41 .

[0126] In this way, the specific shape portion 53 is formed at a position other than the abutting surface portion 52 in the abutting member main body 51 and not in contact with the fixing portion 58 .

[0127] (Eighth Embodiment)

[0128] exist Fig.231 and 2 show a part of the reaction force applying device according to the eighth embodiment. The structure of the contact member 50 according to the eighth embodiment is different from that of the fifth embodiment.

[0129] In the present embodiment, the contact member 50 does not have the member recesses 551 , 552 , 553 , and 554 , and the contact member body 51 is formed in a simple cylindrical shape. In addition, the retaining portion 46 is not provided.

[0130] The specific shape portion 531 is a convex gate mark formed on the contact member body 51 during molding, and is formed on the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Fig.23 The specific shape portion 533 is an annular and convex burr formed on the contact member body 51 during molding, and is formed to protrude radially outward from the end of the contact member body 51 on the opposite side of the connecting rod body 41 (see Fig.23 ).

[0131] In the present embodiment, since the contact member 50 is arranged to be immovable in the axial direction relative to the other end portion 43 of the connecting rod by the fixing portion 58, the surface that can contact the pedal 70, that is, the contact surface portion 52, is set in the axial direction of the outer peripheral wall of the contact member body 51 to a predetermined range R2 on the side of the connecting rod body 41 (see Fig.23 ).

[0132] In this way, the specific shape portion 53 is formed at a position other than the abutting surface portion 52 in the abutting member main body 51 and not in contact with the fixing portion 58 .

[0133] (Ninth Embodiment)

[0134] exist Fig.24 , 25 1 and 2 show a part of the reaction force applying device according to the ninth embodiment. The structures of the contact member 50 and the anti-detachment portion 46 of the ninth embodiment are different from those of the fifth embodiment.

[0135] In the present embodiment, the contact member 50 does not include the member recess 552 but includes the member recess 558 .

[0136] The member recess 551 is formed in an annular shape so as to be recessed in the axial direction from the end surface of the member body 51 on the connecting rod body 41 side (see Fig.24 The member recess 553 is formed in an annular shape so as to be recessed in the axial direction from the outer edge of the end surface of the member body 51 on the connecting rod body 41 side that contacts the member body 51 (see Fig.24 The member recess 554 is formed in an annular shape so as to be recessed in the axial direction from the inner edge of the end surface of the member body 51 on the connecting rod body 41 side that contacts the member body 51 (see Fig.24). In addition, the outer edge of the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 is chamfered (see Fig.24 ).

[0137] The specific shape portion 531 is a convex gate mark formed on the contact component body 51 during molding, and is formed on the bottom surface of the component recess 551 (see Fig.24 The specific shape portion 533 is an annular and convex burr formed on the contact component body 51 during molding, and is formed to protrude from the outer edge of the component recess 553 toward the connecting rod body 41 (see Fig.24 The specific shape portion 534 is an annular and convex burr formed on the contact member body 51 during molding, and is formed to protrude from the inner edge of the member recess 554 toward the connecting rod body 41 (see Fig.24 ).

[0138] The member recess 558 is formed so as to be recessed in the axial direction from the end surface of the contact member body 51 on the opposite side to the connecting rod body 41 (see Fig.24 , Fig.25 Four member recesses 558 are formed at equal intervals in the circumferential direction of the contact member body 51 (see Fig.25 ).

[0139] The specific shape portion 532 is an annular and convex ejector pin mark formed on the contact component body 51 during molding, and is formed on the bottom surface of the component recess 558 (see Fig.24 , Fig.25 Therefore, four specific shape portions 532 are formed at equal intervals in the circumferential direction of the contact member body 51 (see Fig.25 ).

[0140] In this embodiment, the anti-slip part 46 has an anti-slip part body 461 and a rotation-stopping protrusion 462. The anti-slip part body 461 is formed in an annular plate shape. The rotation-stopping protrusion 462 is formed to protrude in the axial direction from the inner edge of the anti-slip part body 461 (see Fig.24 Four anti-rotation protrusions 462 are formed at equal intervals in the circumferential direction of the anti-detachment portion main body 461 (see Fig.25 ).

[0141] The anti-slip part 46 is configured such that the anti-rotation protrusion 462 enters the component recess 558, and the inner edge of the anti-slip part body 461 is pressed into the other end portion 43 of the connecting rod, so that the anti-slip part 46 cannot rotate relative to the other end portion 43 of the connecting rod, and cannot move relative to the axial direction. As a result, the abutting part 50 is clamped by the connecting rod body 41 and the anti-slip part 46 in such a manner that the end face of the abutting part body 51 on the connecting rod body 41 side abuts against the connecting rod body 41, and the end face on the opposite side of the connecting rod body 41 abuts against the anti-slip part body 461. In addition, since the anti-rotation protrusion 462 enters the component recess 558, the relative rotation of the abutting part 50 relative to the other end portion 43 of the connecting rod can be reliably limited.

[0142] The distance between the bottom surface of the component recess 558 and the anti-rotation protrusion 462 is greater than the protrusion height of the specific shape portion 532 (see Fig.24 ). Therefore, the specific shape portion 532 does not contact the anti-rotation protrusion 462.

[0143] In this way, the specific shape portion 53 is formed at a position other than the abutting surface portion 52 in the abutting member main body 51 and not in contact with the fixing portion 58 .

[0146] In the present embodiment, the contact member 50 does not have the member recess 558 .

[0147] In the present embodiment, the anti-slip portion 46 is formed integrally with the other end portion 43 of the connecting rod in a manner that the anti-slip portion 46 extends radially outward in an annular shape from the end portion of the other end portion 43 of the connecting rod on the side opposite to the connecting rod body 41. The anti-slip portion 46 is formed, for example, by riveting. Thus, the abutting component 50 is in a state of being clamped by the connecting rod body 41 and the anti-slip portion 46 in a manner that the end face of the abutting component body 51 on the side of the connecting rod body 41 abuts against the connecting rod body 41, and the end face on the side opposite to the connecting rod body 41 abuts against the anti-slip portion 46.

[0148] The specific shape portion 532 is formed on the end surface of the contact member body 51 on the opposite side to the link body 41, on the radially outer side of the anti-detachment portion 46 (see Fig.26 , Fig. 27 Four specific shape portions 532 are formed at equal intervals in the circumferential direction of the contact member body 51 (see Fig. 27 ).

[0149] In this way, the specific shape portion 53 is formed at a position other than the abutting surface portion 52 in the abutting member main body 51 and not in contact with the fixing portion 58 .
