反力付与装置Reaction force application device 関連出願の相互参照CROSS-REFERENCE TO RELATED APPLICATIONS
　本出願は、２０２２年９月３０日に出願された特許出願番号２０２２－１５９０３７号に基づくものであり、ここにその記載内容を援用する。 This application is based on Patent Application No. 2022-159037, filed on September 30, 2022, the contents of which are incorporated herein by reference.
　本開示は、反力付与装置に関する。 This disclosure relates to a reaction force application device.
　従来、運転者により踏込操作されるペダルを備えるアクセル装置のペダルに対し、運転者の踏込力に対する反力を付与可能な反力付与装置が知られている。
　例えば特許文献１の反力付与装置は、アクセル装置のペダルとともに回転するアームに対し、運転者の踏込力に対する反力を付与可能なレバーを備えている。レバーの先端部には、アームに当接可能かつアームから離間可能でレバーに対し相対回転可能な回転部材が設けられている。 2. Description of the Related Art Conventionally, there has been known a reaction force application device capable of applying a reaction force against a pedal depression force of a driver to an accelerator device having a pedal depressed by a driver.
For example, the reaction force applying device in Patent Document 1 includes a lever that applies a reaction force against a driver's depressing force to an arm that rotates together with the pedal of an accelerator device. A rotating member is provided at the tip of the lever that can come into contact with the arm and be separated from the arm and can rotate relatively to the lever.
特許第５４９１１１５号公報Patent No. 5491115
　ところで、特許文献１のような反力付与装置では、一般に、回転部材は、金属または硬度の高い樹脂等により形成されている。特許文献１の反力付与装置では、例えば運転者がペダルに対する踏込力を急に開放し、回転部材がアームから離間し、アームが初期位置に戻るのに対し遅れてレバーが戻ることがある。これにより、回転部材がアームに衝突し、大きな衝突音が発生するおそれがある。 In a reaction force applying device such as that in Patent Document 1, the rotating member is generally made of metal or a hard resin. In the reaction force applying device in Patent Document 1, for example, if the driver suddenly releases the pressure on the pedal, the rotating member may separate from the arm, and the lever may return with a delay while the arm returns to its initial position. This may cause the rotating member to collide with the arm, generating a loud impact noise.
　本開示の目的は、部材間の衝突音の発生を抑制可能な反力付与装置を提供することにある。 The objective of this disclosure is to provide a reaction force application device that can suppress the generation of collision noise between components.
　本開示は、運転者により踏込操作されるペダルを備えるアクセル装置のペダルに対し運転者の踏込力に対する反力を付与可能な反力付与装置であって、アクチュエータとレバーと当接部材とを備える。アクチュエータは、通電により駆動力を発生させる。レバーは、アクチュエータからの駆動力により回転し、ペダルまたはペダルとともに回転するアームに対し前記反力を付与可能である。当接部材は、ペダルまたはアームに当接可能、かつ、ペダルまたはアームから離間可能なよう、レバーに設けられている。 The present disclosure relates to a reaction force applying device capable of applying a reaction force to a pedal of an accelerator device having a pedal operated by a driver against the force of the driver's depression, the reaction force applying device comprising an actuator, a lever, and an abutment member. The actuator generates a driving force when electricity is passed through it. The lever rotates due to the driving force from the actuator, and is capable of applying the reaction force to the pedal or an arm that rotates together with the pedal. The abutment member is provided on the lever so that it can abut against the pedal or the arm, and can be separated from the pedal or the arm.
　当接部材は、弾性体により形成されている。そのため、例えば運転者がペダルに対する踏込力を急に開放し、当接部材がペダルまたはアームから離間し、ペダルまたはアームが初期位置に戻るのに対し遅れてレバーが戻り、当接部材がペダルまたはアームに衝突したとしても、衝突音の発生を抑制できる。 The contact member is made of an elastic material. Therefore, for example, if the driver suddenly releases the pressure on the pedal, the contact member separates from the pedal or arm, and the lever returns to its original position with a delay, causing the contact member to collide with the pedal or arm, and the generation of a collision sound can be suppressed.
　本開示についての上記目的およびその他の目的、特徴や利点は、添付の図面を参照しながら下記の詳細な記述により、より明確になる。その図面は、

　反力付与装置１０は、アクセル装置６０とともに車両１に搭載され、アクセル装置６０のペダル７０に対し、運転者の踏込力Ｆ１に対する反力Ｆ２を付与可能である。反力付与装置１０は、アクセル装置６０のペダル７０に対し反力を付与することにより、運転者に対する危険通知や燃費改善通知等のドライバ通知を行うことが可能である。また、反力付与装置１０は、ペダル７０の回転を規制することで、ペダル７０をフットレスト化することが可能である。 The reaction force applying device 10 is mounted on the vehicle 1 together with the accelerator device 60, and is capable of applying a reaction force F2 to the pedal 70 of the accelerator device 60 in response to the driver's depression force F1. By applying a reaction force to the pedal 70 of the accelerator device 60, the reaction force applying device 10 is capable of providing the driver with notifications such as danger notices and fuel efficiency improvement notices. In addition, the reaction force applying device 10 is capable of restricting the rotation of the pedal 70, thereby turning the pedal 70 into a footrest.
　図１において、ｘ軸は車両１の進行方向を示し、ｙ軸は車幅方向を示し、ｚ軸は鉛直上方向を示す。以下、特に断らない限り、車両１への取り付け状態におけるアクセル装置６０および反力付与装置１０の形状または構成について説明する。例えば、「上方」または「上側」は、アクセル装置６０または反力付与装置１０が車両１に取り付けられた状態における上方または上側を意味する。また、本実施形態では、フロアパネル２は、ｙｚ平面に平行な壁面７、および、壁面７に対し傾斜する壁面８を有する。 In FIG. 1, 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. Unless otherwise specified, the following describes the shape or configuration of the accelerator device 60 and the reaction force applying device 10 when attached to the vehicle 1. For example, "above" or "upper side" means the upper side or upper side when the accelerator device 60 or the reaction force applying device 10 is attached to the vehicle 1. In addition, in this embodiment, the floor panel 2 has a wall surface 7 that is parallel to the yz plane, and a wall surface 8 that is inclined relative to the wall surface 7.
　アクセル装置６０は、ペダルハウジング６１、ペダル７０等を備える。ペダルハウジング６１は、例えば図示しない取付ボルトにより車両１のフロアパネル２の壁面８に固定されることにより、フロアパネル２に取り付けられる。 The accelerator device 60 includes a pedal housing 61, a pedal 70, etc. The pedal housing 61 is attached to the floor panel 2 by being fixed to the wall surface 8 of the floor panel 2 of the vehicle 1, for example, by a mounting bolt (not shown).
　ペダル７０は、回転軸Ａｘ１周りに回転するよう、ペダルハウジング６１に回転可能に支持されている。ペダル７０には、運転者により踏み込まれるパッド７１が設けられている。ペダルハウジング６１内には、図示しないアクセル開度センサが設けられている。アクセル開度センサは、運転者の踏込操作により回転するペダル７０の回転角に対応するアクセル開度を検出し、ＥＣＵに伝達する。なお、回転軸Ａｘ１は、ｚ軸およびｘ軸に対し直交し、ｙ軸に対し平行になるよう設定されている。 The pedal 70 is rotatably supported by the pedal housing 61 so as to rotate around the rotation axis Ax1. The pedal 70 is provided with a pad 71 that is depressed by the driver. An accelerator opening sensor (not shown) is provided inside the pedal housing 61. The accelerator opening sensor detects the accelerator opening corresponding to the rotation angle of the pedal 70 that rotates when the driver depresses it, and transmits it to the ECU. The rotation axis Ax1 is set to be perpendicular to the z-axis and x-axis, and parallel to the y-axis.
　ペダルハウジング６１内には、図示しないペダル付勢部材が設けられている。ペダル７０は、ペダル付勢部材により、アクセル閉方向に付勢されている。ペダルハウジング６１は、ペダル７０のアクセル閉方向の回転を規制するストッパ、および、アクセル開方向の回転を規制するストッパを有している。ペダル７０は、両ストッパに当接する範囲で回転可能である。図１は、ペダル７０がアクセル閉方向のストッパに当接している状態、すなわち、アクセル全閉の状態を示している。 A pedal biasing member (not shown) is provided inside the pedal housing 61. The pedal 70 is biased in the accelerator closing direction by the pedal biasing member. The pedal housing 61 has a stopper that restricts rotation of the pedal 70 in the accelerator closing direction, and a stopper that restricts rotation in the accelerator opening direction. The pedal 70 can rotate within a range in which it abuts against both stoppers. Figure 1 shows the state in which the pedal 70 abuts against the stopper in the accelerator closing direction, i.e., the accelerator is fully closed.
　図１、２に示すように、反力付与装置１０は、アクチュエータ２０とレバー４０と当接部材５０とを備える。アクチュエータ２０は、通電により駆動力を発生させる。レバー４０は、アクチュエータ２０からの駆動力により回転し、ペダル７０に対し、運転者の踏込力に対する反力を付与可能である。当接部材５０は、ペダル７０に当接可能、かつ、ペダル７０から離間可能なよう、レバー４０に設けられている。当接部材５０は、弾性体により形成されている。 As shown in Figures 1 and 2, the reaction force applying device 10 comprises an actuator 20, a lever 40, and an abutment member 50. The actuator 20 generates a driving force when electricity is applied. The lever 40 rotates by the driving force from the actuator 20, and can apply a reaction force to the pedal 70 against the force applied by the driver. The abutment member 50 is provided on the lever 40 so as to be able to abut against the pedal 70 and also be able to move away from the pedal 70. The abutment member 50 is formed from an elastic body.
　より詳細には、反力付与装置１０は、アクチュエータハウジング１１を備えている。アクチュエータハウジング１１は、例えば図示しない取付ボルトにより車両１のフロアパネル２の壁面７に固定されることにより、フロアパネル２に取り付けられる。 More specifically, the reaction force applying device 10 includes an actuator housing 11. The actuator housing 11 is attached to the floor panel 2 by being fixed to the wall surface 7 of the floor panel 2 of the vehicle 1, for example, by means of mounting bolts (not shown).
　アクチュエータ２０は、例えば電動モータであり、アクチュエータハウジング１１内に収容されている。アクチュエータ２０は、通電により駆動力としてのトルクを出力可能である。ＥＣＵは、アクチュエータ２０への通電を制御し、アクチュエータ２０の作動を制御可能である。アクチュエータハウジング１１には、図示しない複数のギヤからなる減速機が設けられている。当該減速機は、アクチュエータ２０のトルクを減速して軸部材３６から出力可能である。軸部材３６は、回転軸Ａｘ２上に設けられ、回転軸Ａｘ２周りに回転可能にアクチュエータハウジング１１に支持されている。 The actuator 20 is, for example, an electric motor, and is housed in the actuator housing 11. The actuator 20 is capable of outputting torque as a driving force when energized. The ECU controls the energization of the actuator 20 and is capable of controlling the operation of the actuator 20. The actuator housing 11 is provided with a reduction gear consisting of multiple gears (not shown). The reduction gear is capable of reducing the torque of the actuator 20 and outputting 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 so as to be rotatable around the rotation axis Ax2.
　レバー４０は、レバー本体４１、レバー一端部４２、レバー他端部４３等を有している。レバー本体４１は、例えば金属等により棒状に形成されている。レバー一端部４２は、レバー本体４１の一端に接続し、レバー本体４１と一体に形成されている。レバー他端部４３は、レバー本体４１の他端に接続し、レバー本体４１と一体に形成されている。レバー他端部４３は、レバー本体４１に対し略直角となるよう形成されている。レバー他端部４３は、ｙ軸と平行になるよう設けられている。 The lever 40 has a lever body 41, one lever end 42, the other lever end 43, etc. The lever body 41 is formed in a rod shape from, for example, metal, etc. The one lever end 42 is connected to one end of the lever body 41 and is formed integrally with the lever body 41. The other lever end 43 is connected to the other end of the lever body 41 and is formed integrally with the lever body 41. The other lever end 43 is formed so as to be approximately perpendicular to the lever body 41. The other lever end 43 is arranged so as to be parallel to the y-axis.
　レバー４０は、レバー一端部４２が軸部材３６に接続するよう設けられている。これにより、レバー４０は、軸部材３６とともに回転軸Ａｘ２周りに回転するよう、アクチュエータハウジング１１に回転可能に支持されている。レバー４０は、軸部材３６から出力されるアクチュエータ２０からの駆動力により、回転軸Ａｘ２周りに回転する。 The lever 40 is provided so that one end 42 of the lever is connected to the shaft member 36. As a result, the lever 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 lever 40 rotates around the rotation axis Ax2 due to the driving force from the actuator 20 output from the shaft member 36.
　当接部材５０は、レバー４０のアクチュエータ２０とは反対側の端部である先端においてレバー４０に対し相対回転不能に固定されている。 The contact member 50 is fixed to the lever 40 at the tip, which is the end of the lever 40 opposite the actuator 20, so that it cannot rotate relative to the lever 40.
　当接部材５０は、レバー４０の先端に圧入、熱圧入、インサート成形または接着により固定されている。 The abutment member 50 is fixed to the tip of the lever 40 by press fitting, heat press fitting, insert molding or adhesive.
　当接部材５０の硬度は、レバー４０の硬度よりも低い。 The hardness of the contact member 50 is lower than the hardness of the lever 40.
　より詳細には、当接部材５０は、例えばフッ素樹脂、ＰＥ、ＰＵ、ＰＯＭ、ＴＰＥＥ、ＴＰＣ等の摺動性に優れた樹脂等の弾性体により、略円筒状に形成されている。当接部材５０は、レバー他端部４３に挿入され、圧入、熱圧入、インサート成形または接着によりレバー他端部４３に固定されている。これにより、当接部材５０は、レバー他端部４３に対し相対回転不能である。当接部材５０は、樹脂により形成されており、金属により形成されたレバー４０よりも硬度が低い。 More specifically, the abutment member 50 is formed in a generally cylindrical shape from an elastic body such as a resin with excellent sliding properties, such as fluororesin, PE, PU, POM, TPEE, or TPC. The abutment member 50 is inserted into the other end 43 of the lever and fixed to the other end 43 of the lever by press-fitting, hot press-fitting, insert molding, or bonding. This makes the abutment member 50 unable to rotate relative to the other end 43 of the lever. The abutment member 50 is formed from resin and has a lower hardness than the lever 40, which is formed from metal.
　図１に示すように、反力付与装置１０は、当接部材５０の外周壁がアクセル装置６０のペダル７０のフロアパネル２側の面に当接可能、かつ、ペダル７０のフロアパネル２側の面から離間可能に設けられる。これにより、反力付与装置１０は、アクチュエータ２０からの駆動力により回転するレバー４０から当接部材５０を経由して、運転者の踏込力Ｆ１に対する反力Ｆ２をペダル７０に対し付与可能である。 As shown in FIG. 1, the reaction force applying device 10 is provided so that the outer peripheral wall of the abutment member 50 can abut against the surface of the pedal 70 of the accelerator device 60 on the floor panel 2 side, and can be separated from the surface of the pedal 70 on the floor panel 2 side. As a result, the reaction force applying device 10 can apply a reaction force F2 against the driver's depression force F1 to the pedal 70 from the lever 40, which rotates due to the driving force from the actuator 20, via the abutment member 50.
　ここで、例えば運転者がペダル７０に対する踏込力Ｆ１を急に開放し、当接部材５０がペダル７０から離間し、ペダル７０が初期位置に戻るのに対し遅れてレバー４０が戻り、当接部材５０がペダル７０に衝突することがある。本実施形態では、当接部材５０が弾性体により形成されているため、当接部材５０がペダル７０に衝突しても、衝突音の発生を抑制できる。 For example, if the driver suddenly releases the depression force F1 on the pedal 70, the abutment member 50 moves away from the pedal 70, and the lever 40 returns with a delay while the pedal 70 returns to its initial position, causing the abutment member 50 to collide with the pedal 70. In this embodiment, the abutment member 50 is made of an elastic body, so that even if the abutment member 50 collides with the pedal 70, the generation of a collision sound can be suppressed.
　また、本実施形態では、運転者がペダル７０を踏込操作するとき、当接部材５０は、ペダル７０に対し摺動する。より詳細には、このとき、当接部材５０の外周壁は、ペダル７０のフロアパネル２側の面に対し摺動する。 In addition, in this embodiment, when the driver depresses the pedal 70, the contact member 50 slides against the pedal 70. More specifically, at this time, the outer peripheral wall of the contact member 50 slides against the surface of the pedal 70 on the floor panel 2 side.
　本実施形態では、当接部材５０がレバー４０に対し相対回転せずに、ペダル７０に対し摺動することで、ペダル７０と当接部材５０との間に異物が入り込んだとしても、この異物を当接部材５０により掻き落とすことができる。 In this embodiment, the contact member 50 slides against the pedal 70 without rotating relative to the lever 40, so even if a foreign object gets between the pedal 70 and the contact member 50, the foreign object can be scraped off by the contact member 50.
　なお、本実施形態では、当接部材５０が摺動性に優れた材料により形成されているため、当接部材５０とペダル７０との摺動を円滑にすることができる。 In addition, in this embodiment, the contact member 50 is made of a material with excellent sliding properties, which allows for smooth sliding between the contact member 50 and the pedal 70.
　また、本実施形態は、アクチュエータ２０を収容し車両１に取り付け可能なアクチュエータハウジング１１を備えている。当接部材５０は、アクチュエータハウジング１１の外部において車両１の車室内に露出するよう設けられている。 This embodiment also includes an actuator housing 11 that houses the actuator 20 and can be attached to the vehicle 1. The abutment member 50 is provided outside the actuator housing 11 so as to be exposed to the interior of the vehicle 1.
　当接部材５０を車室内に露出させることにより、異物対策が不要になるため、反力付与装置１０の構成を簡素化できる。 By exposing the contact member 50 inside the vehicle cabin, measures against foreign objects are not necessary, and the configuration of the reaction force applying device 10 can be simplified.
　以上説明したように、本実施形態では、当接部材５０は、ペダル７０に当接可能、かつ、ペダル７０から離間可能なよう、レバー４０に設けられている。 As described above, in this embodiment, the abutment member 50 is provided on the lever 40 so that it can abut against the pedal 70 and can be separated from the pedal 70.
　当接部材５０は、弾性体により形成されている。そのため、例えば運転者がペダル７０に対する踏込力Ｆ１を急に開放し、当接部材５０がペダル７０から離間し、ペダル７０が初期位置に戻るのに対し遅れてレバー４０が戻り、当接部材５０がペダル７０に衝突したとしても、衝突音の発生を抑制できる。 The contact member 50 is made of an elastic material. Therefore, for example, if the driver suddenly releases the depression force F1 on the pedal 70, the contact member 50 moves away from the pedal 70, and the lever 40 returns with a delay while the pedal 70 returns to its initial position, causing the contact member 50 to collide with the pedal 70, the generation of a collision sound can be suppressed.
　また、本実施形態では、当接部材５０は、レバー４０のアクチュエータ２０とは反対側の端部である先端においてレバー４０に対し相対回転不能に固定されている。 In addition, in this embodiment, the contact member 50 is fixed to the tip of the lever 40, which is the end of the lever 40 opposite the actuator 20, so that it cannot rotate relative to the lever 40.
　そのため、運転者がペダル７０を踏込操作するとき、当接部材５０を、ペダル７０に対し摺動させることができる。これにより、ペダル７０と当接部材５０との間に異物が入り込んだとしても、この異物を当接部材５０により掻き落とすことができる。したがって、運転者によるペダル７０の操作フィーリングの悪化を抑制できる。 As a result, when the driver depresses the pedal 70, the contact member 50 can slide against the pedal 70. As a result, even if a foreign object gets between the pedal 70 and the contact member 50, the foreign object can be scraped off by the contact member 50. This makes it possible to prevent a deterioration in the feeling of operation of the pedal 70 by the driver.
　当接部材５０は、レバー４０の先端に圧入、熱圧入、インサート成形または接着により固定されている。 The abutment member 50 is fixed to the tip of the lever 40 by press fitting, heat press fitting, insert molding or adhesive.
　そのため、当接部材５０をレバー４０に対し容易に固定できる。 This makes it easy to fix the contact member 50 to the lever 40.
　当接部材５０の硬度は、レバー４０の硬度よりも低い。 The hardness of the contact member 50 is lower than the hardness of the lever 40.
　そのため、当接部材５０がペダル７０に衝突したとしても、衝突音の発生をより一層抑制できる。 As a result, even if the contact member 50 collides with the pedal 70, the generation of collision noise can be further suppressed.
　　（第２実施形態）
　第２実施形態の反力付与装置、および、それを適用したアクセル装置を図４、５に示す。第２実施形態は、反力付与装置１０およびアクセル装置６０の構成が第１実施形態と異なる。 Second Embodiment
A reaction force application device of a second embodiment and an accelerator device to which the reaction force application device is applied are shown in Figures 4 and 5. In the second embodiment, the configurations of the reaction force application device 10 and the accelerator device 60 are different from those of the first embodiment.
　本実施形態では、アクセル装置６０のペダルハウジング６１は、例えば図示しない取付ボルトにより車両１のフロアパネル２の壁面７に固定されることにより、フロアパネル２に取り付けられる。 In this embodiment, the pedal housing 61 of the accelerator device 60 is attached to the floor panel 2 by being fixed to the wall surface 7 of the floor panel 2 of the vehicle 1, for example, by a mounting bolt (not shown).
　ペダル７０は、パッド７１、ペダル基部７２、ペダル接続部７３を有している。ペダル接続部７３は、例えば金属により形成され、一端がパッド７１に接続し、他端がペダル基部７２に接続するよう、パッド７１とペダル基部７２とを接続している。ペダル基部７２は、回転軸Ａｘ１周りに回転するよう、ペダルハウジング６１に回転可能に支持されている。これにより、ペダル７０は、回転軸Ａｘ１周りに回転可能である。 The pedal 70 has a pad 71, a pedal base 72, and a pedal connection part 73. The pedal connection part 73 is formed, for example, from a metal, and connects the pad 71 and the pedal base 72 such that one end is connected to the 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. This allows the pedal 70 to rotate around the rotation axis Ax1.
　本実施形態では、アクセル装置６０は、アーム８０をさらに備えている。アーム８０は、例えば金属により長尺の板状に形成した部材を所定箇所で折り曲げるようにして形成されている（図５参照）。アーム８０は、一方の端部がペダル基部７２に接続するようにしてペダル７０に取り付けられている。これにより、アーム８０は、ペダル７０とともに回転軸Ａｘ１周りに回転可能である。 In this embodiment, the accelerator device 60 further includes an arm 80. The arm 80 is formed, for example, by bending a long metal plate at a predetermined location (see FIG. 5). The arm 80 is attached to the pedal 70 with one end connected to the pedal base 72. This allows the arm 80 to rotate around the rotation axis Ax1 together with the pedal 70.
　本実施形態では、反力付与装置１０のアクチュエータハウジング１１は、例えば図示しない取付ボルトにより、車両１のフロアパネル２の壁面７に設けられた台座９に固定されることで、台座９を介してフロアパネル２に取り付けられる。 In this embodiment, the actuator housing 11 of the reaction force applying device 10 is attached to the floor panel 2 via the base 9 by being fixed to the base 9 on the wall surface 7 of the floor panel 2 of the vehicle 1, for example, by a mounting bolt (not shown).
　本実施形態では、反力付与装置１０は、第１実施形態と比べ、レバー４０のレバー本体４１の長さが短い。 In this embodiment, the length of the lever body 41 of the lever 40 in the reaction force applying device 10 is shorter than that in the first embodiment.
　図４に示すように、反力付与装置１０は、当接部材５０の外周壁がアクセル装置６０のアーム８０のフロアパネル２とは反対側の面に当接可能、かつ、アーム８０のフロアパネル２とは反対側の面から離間可能に設けられる。これにより、反力付与装置１０は、アクチュエータ２０からの駆動力により回転するレバー４０から当接部材５０およびアーム８０を経由して、運転者の踏込力Ｆ１に対する反力Ｆ２をペダル７０に対し付与可能である。 As shown in FIG. 4, the reaction force applying device 10 is provided so that the outer peripheral wall of the abutment member 50 can abut against the surface of the arm 80 of the accelerator device 60 on the side opposite the floor panel 2, and can be separated from the surface of the arm 80 on the side opposite the floor panel 2. As a result, the reaction force applying device 10 can apply a reaction force F2 against the driver's depression force F1 to the pedal 70 via the abutment member 50 and the arm 80 from the lever 40, which rotates due to the driving force from the actuator 20.
　ここで、例えば運転者がペダル７０に対する踏込力Ｆ１を急に開放し、当接部材５０がアーム８０から離間し、アーム８０が初期位置に戻るのに対し遅れてレバー４０が戻り、当接部材５０がアーム８０に衝突することがある。本実施形態では、当接部材５０が弾性体により形成されているため、当接部材５０がアーム８０に衝突しても、衝突音の発生を抑制できる。 For example, if the driver suddenly releases the depression force F1 on the pedal 70, the abutment member 50 moves away from the arm 80, and the arm 80 returns to its initial position, but the lever 40 returns with a delay, causing the abutment member 50 to collide with the arm 80. In this embodiment, the abutment member 50 is made of an elastic body, so that even if the abutment member 50 collides with the arm 80, the generation of a collision sound can be suppressed.
　本実施形態は、上述した構成以外、第１実施形態と同様である。そのため、第１実施形態と同様の構成については、第１実施形態と同様の作用効果を奏することができる。 This embodiment is similar to the first embodiment except for the configuration described above. Therefore, the same configuration as the first embodiment can achieve the same effects as the first embodiment.
　　（第３実施形態）
　第３実施形態の反力付与装置の一部を図６に示す。第３実施形態は、レバー４０および当接部材５０の構成が第１実施形態と異なる。 Third Embodiment
A part of a reaction force application device of the third embodiment is shown in Fig. 6. In the third embodiment, the configurations of a lever 40 and an abutment member 50 are different from those of the first embodiment.
　本実施形態では、当接部材５０は、レバー他端部４３に対し相対回転可能に設けられている。 In this embodiment, the abutment member 50 is arranged to be rotatable relative to the other end 43 of the lever.
　レバー４０は、抜け止め部４６を有している。抜け止め部４６は、例えば金属により、環状の板状に形成されている。レバー他端部４３には、係合溝部４３１が形成されている。係合溝部４３１は、当接部材５０に対しレバー本体４１とは反対側において、レバー他端部４３のレバー本体４１とは反対側の端部の外周壁から径方向内側に凹むよう環状に形成されている。 The lever 40 has a retaining portion 46. The retaining portion 46 is formed in a ring-shaped plate shape, for example, from metal. An engagement groove portion 431 is formed in the other end portion 43 of the lever. The engagement groove portion 431 is formed in a ring shape on the opposite side of the lever body 41 from the abutment member 50, so as to be recessed radially inward from the outer circumferential wall of the end portion of the lever other end portion 43 opposite the lever body 41.
　抜け止め部４６は、内縁部が係合溝部４３１に嵌まり込んで係合するようレバー他端部４３に設けられている。これにより、レバー他端部４３からの当接部材５０の脱落を規制できる。 The anti-slip portion 46 is provided on the other end 43 of the lever so that the inner edge fits into and engages with the engagement groove 431. This prevents the abutment member 50 from falling off from the other end 43 of the lever.
　　（他の実施形態）
　上述の実施形態では、当接部材をフッ素樹脂、ＰＥ、ＰＵ、ＰＯＭ、ＴＰＥＥ、ＴＰＣ等の弾性体により形成する例を示した。これに対し他の実施形態では、当接部材は、弾性体であれば、どのような材料により形成してもよい。 Other Embodiments
In the above-described embodiment, the contact member is formed of an elastic material such as fluororesin, PE, PU, POM, TPEE, TPC, etc. In contrast, in other embodiments, the contact member may be formed of any material as long as it is an elastic material.
　また、上述の実施形態では、当接部材が、レバーの先端に圧入、熱圧入、インサート成形または接着により固定される例を示した。これに対し他の実施形態では、当接部材は、レバーの先端に圧入、熱圧入、インサート成形または接着以外の方法により固定されてもよい。 In the above-described embodiment, an example was shown in which the contact member is fixed to the tip of the lever by press fitting, heat press fitting, insert molding, or adhesion. In contrast, in other embodiments, the contact member may be fixed to the tip of the lever by a method other than press fitting, heat press fitting, insert molding, or adhesion.
　また、上述の実施形態では、当接部材の硬度が、レバーの硬度よりも低い例を示した。これに対し他の実施形態では、当接部材の硬度は、レバーの硬度以上であってもよい。 In the above embodiment, an example was shown in which the hardness of the contact member was lower than the hardness of the lever. In contrast, in other embodiments, the hardness of the contact member may be equal to or greater than the hardness of the lever.
　また、上述の第３実施形態では、レバーの先端に、環状かつ板状の抜け止め部を設ける例を示した。これに対し他の実施形態では、抜け止め部は、例えばＣ字状のスナップリングであってもよい。あるいは、抜け止め部は、レバーの先端と一体に鍔状に形成されていてもよい。 In the third embodiment described above, an example was shown in which a ring-shaped, plate-shaped retaining portion was provided at the tip of the lever. In contrast, in other embodiments, the retaining portion may be, for example, a C-shaped snap ring. Alternatively, the retaining portion may be formed in the shape of a flange integral with the tip of the lever.
　また、他の実施形態では、反力付与装置およびアクセル装置が取り付けられる車両のフロアパネルの壁面は、ｙｚ平面に対し平行となるよう形成されていなくてもよい。つまり、フロアパネルの壁面は、車両に対しどのような角度で形成されていてもよい。 In other embodiments, the wall surface of the floor panel of the vehicle to which the reaction force application device and accelerator device are attached does not have to be formed parallel to the yz plane. In other words, the wall surface of the floor panel may be formed at any angle relative to the vehicle.
　また、本開示による反力付与装置およびアクセル装置は、車両以外の乗物にも適用することができる。 The reaction force application device and accelerator device disclosed herein can also be applied to vehicles other than automobiles.
