Modes for Carrying Out the Invention

[0017] Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples.

[0018] FIG. 1 is a schematic diagram showing the configuration of a vehicle according to an embodiment. Note that this figure illustrates the functional relationship between the components of the vehicle and does not specify the specific arrangement of each component. As shown in the figure, in some embodiments, the vehicle 1 is a motorcycle configured such that a driver can straddle the seat 2 and sit, and hold the handle 3 to drive. The handle 3 is provided with a throttle grip 10 for the driver to adjust the throttle opening. The output of the engine 20 is adjusted according to the operation amount of the throttle grip 10.

[0019] In the exemplary embodiment shown in FIG. 1, the output of the engine 20 is adjusted according to the operation amount of the throttle grip 10 by an electronic control system called throttle-by-wire. Specifically, the operation of the throttle grip 10 is detected by an APS (Accelerator Position Sensor; referred to as a throttle position sensor in this specification) 12. The operation detection result of the throttle grip 10 by the APS 12 is sent to an engine control unit (ECU) 14. The ECU 14 generates a throttle valve opening command value θ* according to the signal from the APS 12 and sends it to a TBW (Throttle-By-Wire System) 16. At this time, the ECU 14 may acquire the state quantities of the vehicle 1 such as the rotational speed ω of the engine 20 and the throttle valve opening θ, and generate the opening command value θ* based on these state quantities of the vehicle 1 and the signal from the APS 12. The TBW16 adjusts the opening degree of the throttle valve based on the opening command value θ*, which is an input signal from the ECU14, by an actuator that may be a motor, for example. In this way, the output of the engine 20 is controlled according to the operation amount of the throttle grip 10 via the electronic control system.

[0020] In other embodiments, the opening degree of the throttle valve is directly adjusted by operating the throttle grip 10 via a throttle wire (mechanical wire) not shown, so that the output of the engine 20 is controlled according to the operation amount of the throttle grip 10.

[0021] The vehicle 1 configured as described above includes a reaction force applying device (RFI) 100 for applying a reaction force to the throttle grip 10 according to the running state for the purpose of prompting the driver to drive stably. The reaction force applying device 100 adjusts the reaction force applied to the throttle grip 10 according to a signal from the ECU14. Note that the reaction force applied to the throttle grip 10 by the reaction force applying device 100 is a reaction force in the direction of closing the accelerator (the direction of reducing the output of the engine 20), and hereinafter, this reaction force is referred to as the "reaction force in the closing direction".

[0022] FIG. 2 is a schematic diagram showing the configuration of the reaction force applying device 100 according to an embodiment. FIG. 3 is a view showing the throttle plate of the reaction force applying device 100 in an embodiment. FIGS. 4A and 4B are views showing the configuration of the rotating plate of the reaction force applying device 100 in an embodiment, FIG. 4A shows the reaction force transmission cutoff state, and FIG. 4B shows the reaction force transmission state.

[0023] As shown in FIG. 2, in some embodiments, the reaction force applying device 100 includes a throttle plate 110 that rotates in conjunction with the throttle grip 10, a reaction force transmission unit 200 for transmitting a reaction force to the throttle plate 110, and a reaction force generation unit 300 for generating a reaction force in the closing direction.

[0024] The throttle plate 110 is configured to be rotatable about a rotation axis O (see FIG. 3) in conjunction with the throttle grip 10 of the vehicle 1. As shown in FIG. 3, the rotation range of the throttle plate 110 is defined by an angular range Δθ (= θmax - θmin) between a minimum opening position θmin corresponding to full throttle closure (fully closed throttle valve) and a maximum opening position θmax corresponding to full throttle opening (fully open throttle valve). The angular position of the throttle plate 110 is adjustable to any position between the minimum opening position θmin and the maximum opening position θmax. In the example shown in FIG. 3, the angular position of the throttle plate 110 is defined based on the position of an engagement portion 112 described later.

[0025] In some embodiments, as shown in FIGS. 2 and 3, the operation of the throttle grip 10 is transmitted to the throttle plate 110 via a throttle wire 111 (mechanical wire), and the throttle plate 110 rotates according to the operation amount of the throttle grip 10. In the example shown in FIG. 3, when the throttle is closed by the throttle grip 10, the throttle plate 110 rotates in the first direction A. Conversely, when the throttle is opened by the throttle grip 10, the throttle plate 110 rotates in the direction opposite to the first direction A.

[0026] As shown in FIGS. 2 and 3, the throttle plate 110 has an engagement portion 112 that can engage with a reaction force applying portion 212 of a rotation plate 210 of a reaction force transmission portion 200 described later. The configuration of the engagement portion 112 is not particularly limited as long as it can engage with the reaction force applying portion 212 of the rotation plate 210 and may have any shape. In the exemplary embodiments shown in FIGS. 2 and 3, the engagement portion 112 is a convex portion that protrudes radially outward from the throttle plate 110. In other embodiments, the engagement portion 112 is a lever that extends axially toward the rotation plate 210.

[0027] As shown in FIG. 2, the throttle plate 110 may be biased in the first direction A (see FIG. 3; the rotation direction of the throttle plate 110 corresponding to the closing direction of the accelerator grip 10) by a spring (second spring) 120. In this case, unless the driver operates the throttle grip 10 to intentionally open the accelerator, the throttle grip 10 is closed by the spring (second spring) 120, and the output of the engine 20 decreases. Further, since the throttle plate 110 is interlocked with the throttle grip 10, the angle position of the throttle plate 110 may be detected as the operation amount of the throttle grip 10 by the above-described APS 12. In this case, as shown in FIG. 2, the APS 12 may be disposed on the side opposite to the reaction force transmission portion 200 with the throttle plate 110 interposed therebetween.

[0028] As shown in FIG. 2, the reaction force transmission portion 200 includes a rotation plate 210 configured to be rotatable independently of the throttle plate 110. The rotation plate 210 is disposed to face the throttle plate 110 in the axial direction along the rotation axis of the throttle plate 110. As shown in FIGS. 2 to 4B, the rotation plate 210 is provided with a reaction force applying portion 212 that can engage with the engaging portion 112 of the throttle plate 110. The configuration of the reaction force applying portion 212 of the rotation plate 210 is not particularly limited as long as it can engage with the engaging portion 112 of the throttle plate 110, and may have any shape. In the exemplary embodiment shown in FIG. 2, the reaction force applying portion 212 is a lever that extends in the direction along the rotation axis of the rotation plate 210 toward the convex portion (engaging portion 112) protruding radially outward from the throttle plate 110. In other embodiments, the reaction force applying portion 212 is a convex portion protruding radially outward from the rotation plate 210, and the engaging portion 112 extends axially from the throttle plate 110 toward this convex portion, so that the reaction force applying portion 212 and the engaging portion 112 can be engaged with each other.

[0029] In the embodiments shown in FIGS. 3 to 4B, the reaction force applying portion 212 is located upstream with respect to the engaging portion 112 of the throttle plate 110 in the first direction A. As a result, when the reaction force applying portion 212 presses the engaging portion 112 in the first direction A (closing direction), the reaction force in the closing direction by the reaction force generating unit 300 is transmitted to the throttle plate 110. Note that FIGS. 3 and 4A show a state in which the transmission of the reaction force to the throttle plate 110 by the reaction force transmitting unit 200 is blocked, and the reaction force applying portion 212 is separated from the engaging portion 112. On the contrary, when applying the reaction force, as the rotation plate 210 rotates, the reaction force applying portion 212 comes into contact with the engaging portion 112, and the engaging portion 112 is pressed in the first direction A by the reaction force applying portion 212 (see FIG. 4B).

[0030] In some embodiments, as shown in FIGS. 3 and 4A, the rotation plate 210 is configured to be rotatable within an angular range Δθ including a first angular position θ1 where the reaction force applying portion 212 retracts from the engaging portion 112 when the throttle plate 110 is at the maximum opening position θmax. 12 When reaction force application is not required, the angular position of the rotation plate 210 is adjusted within the angular range Δθ such that the reaction force applying portion 212 separates from the engaging portion 112. Thereby, regardless of the angular position of the throttle plate 110, the transmission of the reaction force from the reaction force transmitting unit 200 can be blocked, and the influence of the reaction force applying device 100 on the operability can be reduced. 12

[0031] For example, as shown in FIGS. 3 and 4A, when the rotation plate 210 is at the first angular position θ1, even if the throttle plate 110 moves to the maximum opening position θmax, the reaction force applying portion 212 does not contact the engaging portion 112. Therefore, if the rotation plate 210 is rotated to the first angular position θ1, the transmission of the reaction force to the throttle plate 110 via the reaction force transmitting unit 200 is blocked. In contrast, for example, as shown in FIG. 4B, when the rotation plate 210 rotates to an angle θ' within the angular range Δθ 12 the reaction force applying portion 212 comes into contact with the engaging portion 112, and the reaction force in the closing direction is transmitted to the throttle plate 110 via the reaction force transmitting unit 200. ​​In the example shown in FIGS. 3 to 4B, the angular position of the rotation plate 210 is defined based on the position of the reaction force applying portion 212.

[0032] In some embodiments, as shown in FIG. 3, the angular range Δθ 12 in which the rotation plate 210 can rotate is wider than the movable range of the throttle plate 110. That is, Δθ 12 is larger than the angular range Δθ between the minimum angular position θmin and the maximum angular position θmax of the throttle plate 110. Thereby, regardless of the angular position of the throttle plate 110, either a state where the reaction force applying portion 212 of the rotation plate 210 is in contact with the engaging portion 112 of the throttle plate 110 or a state where the two are separated can be selectively realized. Therefore, throughout the entire movable range (Δθ) of the throttle plate 110, the presence or absence of reaction force transmission in the reaction force transmission unit 200 can be switched according to the necessity of applying a reaction force.

[0033] On the opposite side of the throttle plate 110 across the reaction force transmission unit 200, as shown in FIG. 2, a reaction force generation unit 300 is provided. The specific configuration of the reaction force generation unit 300 is not particularly limited as long as it can generate a reaction force in the closing direction to be applied to the throttle grip 10. For example, a configuration may be adopted in which an actuator such as a motor or a hydraulic cylinder generates torque of a desired magnitude and this torque is directly input as a reaction force to the rotation plate 210 of the reaction force transmission unit 200. Alternatively, the torque from the actuator may be input to the rotation plate 210 via a spring.

[0034] In the embodiment shown in FIG. 2, the reaction force generation unit 300 includes an actuator 302, an intermediate plate 310 driven by the actuator 302, and a first spring 320 for biasing the rotation plate 210 in a first direction A (see FIGS. 3 to 4B) with respect to the intermediate plate 310. The actuator 302 includes, for example, a DC motor and can control the angular position of the intermediate plate 310. The intermediate plate 310 is coaxially provided rotatably independently of the rotating plate 210 of the reaction force transmission unit 200 described above. A first spring 320 is provided between the intermediate plate 310 and the rotating plate 210, and the rotating plate 210 is biased in a first direction A with respect to the intermediate plate 310 by the first spring 320. As a result, the reaction force applying portion 212 of the rotating plate 210 is biased in the first direction A toward the engaging portion 112 of the throttle plate 110.

[0035] In the reaction force generation unit 300 having the above configuration, as a result of the angular position control of the intermediate plate 310 by the actuator 302, the elastic force generated in the first spring 320 is input to the rotating plate 210 as a reaction force in the first direction A (closed direction). In this case, compared with other embodiments in which the torque of the actuator is directly input to the rotating plate, sudden fluctuations in the reaction force transmitted to the throttle plate 110 are suppressed, enabling the driver to receive a natural reaction force through the throttle grip 10.

[0036] As shown in FIG. 2, the actuator 302 is disposed laterally of the throttle plate 110 and the reaction force transmission unit 200. In this case, the output shaft 303 of the actuator 302 may be parallel to the rotation axes of the throttle plate 110 and the reaction force transmission unit 200. In this way, by arranging the actuator 302, the throttle plate 110, and the reaction force transmission unit 200 side by side, the reaction force applying device 100 can be made more compact.

[0037] In some embodiments, as shown in FIG. 4A, the reaction force generation unit 300 has a first stopper 312 that restricts the movement of the rotating plate 210 in the first direction A by the biasing force of the first spring 320. In the exemplary embodiment shown in FIG. 4A, the first stopper 312 is located on the downstream side in the first direction A with respect to the convex portion 222 provided on the outer periphery of the rotating plate 210, and is configured to be able to restrict the movement of the rotating plate 210 in the first direction A by contacting the convex portion 222.

[0038] The first stopper 312 is configured to be movable in the circumferential direction of the rotating plate 210 as the intermediate plate 310 rotates. That is, as the intermediate plate 310 rotates, the angular position of the first stopper 312 is within an angular range Δθ between the third angular position θ3 and the fourth angular position θ4 on the downstream side in the first direction A from the third angular position θ3. 34 It can be changed. In other words, within the angular range Δθ34 in which the first stopper 312 is movable, the third angular position θ3 exists on the most upstream side with respect to the first direction A, and the fourth angular position θ4 exists on the most downstream side with respect to the first direction A. In one embodiment, the first stopper 312 is provided on the intermediate plate 310 so as to be movable in the circumferential direction of the rotating plate 210 in conjunction with the intermediate plate 310. For example, the first stopper 312 is an extension extending from the intermediate plate 310 toward the rotating plate 210, and the extension of the intermediate plate 310 may be configured to lock the convex portion 222 on the downstream side in the first direction A with respect to the convex portion 222 on the outer periphery of the rotating plate 210.

[0039] When no reaction force is required, the intermediate plate 310 is controlled by the actuator 302 to an angular position such that the reaction force applying portion 212 is separated from the engaging portion 112 and the convex portion 222 is locked by the first stopper 312 interlocking with the intermediate plate 310. Thereby, the transmission of the reaction force from the reaction force transmission portion 200 to the throttle plate 110 is blocked. In the reaction force transmission blocking state shown in FIG. 4A, as a result of the convex portion 222 being locked by the first stopper 312 at the third angular position θ3, the rotating plate 210 is held at the first angular position θ1. As described above, when the rotating plate 210 is located at the first angular position θ1, even if the throttle plate 110 is at the maximum opening position θmax, the reaction force applying portion 212 does not contact the engaging portion 112.

[0040] On the other hand, when it is necessary to apply a reaction force to the throttle grip 10, the intermediate plate 310 is controlled by the actuator 302 to an angular position where the first stopper 312 moves away from the convex portion 222 to the downstream side in the first direction A. That is, the actuator 302 controls the angular position of the intermediate plate 310 so as to retract the first stopper 312 to the downstream side in the first direction A with respect to the convex portion 222 of the rotation plate 210. As a result, the rotation plate 210 that receives the biasing force from the first spring 320 in the first direction A rotates to an angular position where the reaction force applying portion 212 contacts the engaging portion 112 of the throttle plate 110. In the reaction force transmission state shown in FIG. 4B, as a result of the angular position of the first stopper 312 interlocked with the intermediate plate 310 being controlled to θ'', the rotation plate 210 rotates in the first direction A to the angular position θ' by the biasing force of the first spring 320. At this time, the reaction force applying portion 212 of the rotation plate 210 is in contact with the engaging portion 112 of the throttle plate 110. Further, the first stopper 312 is located at a position away from the convex portion 222 of the rotation plate 210 to the downstream side in the first direction A, and the locking of the convex portion 222 by the first stopper 312 is released.

[0041] As described above, the switching between the reaction force transmission blocking state shown in FIG. 4A and the reaction force transmission state shown in FIG. 4B is performed by controlling the angular position of the intermediate plate 310 by the actuator 302. As shown in FIG. 4A, when the actuator 302 controls the angular position of the intermediate plate 310 (the first stopper 312) to θ3, as a result of the first stopper 312 locking the convex portion 222, the rotation plate 210 does not rotate in the first direction A due to the biasing force of the first spring 320. Therefore, the reaction force applying portion 212 of the rotation plate 210 cannot contact the engaging portion 112 of the throttle plate 110, and the reaction force transmission to the throttle plate 110 by the reaction force transmission portion 200 is blocked. On the other hand, as shown in FIG. 4B, when the actuator 302 controls the angular position of the intermediate plate 310 (the first stopper 312) to θ'', the rotation plate 210 rotates in the first direction A by the biasing force of the first spring 320 until the reaction force applying portion 212 contacts the engaging portion 112 of the throttle plate 110. As a result, the reaction force applying portion 212 of the rotation plate 210 presses the engaging portion 112 in the first direction A, and the reaction force is transmitted to the throttle plate 110 by the reaction force transmitting portion 200 (see FIG. 4B).

[0042] In some embodiments, as shown in FIG. 2, the reaction force generating unit 300 includes a bearing 340 for pivotally supporting the rotation plate 210 independently of the intermediate plate 310 whose angular position is controlled by the actuator 302. Specifically, the reaction force generating unit 300 includes a support shaft 330 provided on the outer periphery of the intermediate plate 310 and a bearing 340 that rotatably supports the rotation plate 210 with respect to the support shaft 330. The support shaft 330 is connected to the actuator 302, and its angular position can be controlled by the actuator 302. The intermediate plate 310 is fixed to the outer periphery of the support shaft 330 and rotates together with the support shaft 330. On the other hand, since the rotation plate 210 is supported by the support shaft 330 via the bearing 340, the rotation plate 210 and the intermediate plate 310 can rotate coaxially independently of each other. In the exemplary embodiment shown in FIG. 2, the support shaft 330 extends axially toward the rotation plate 210 inside the diameter of the first spring 320 so as to be surrounded by the first spring 320 described above.

[0043] A plurality of gears 350 may be provided between the actuator 302 and the support shaft 330. Thereby, the speed ratio between the output shaft 303 of the actuator 302 and the support shaft 330 can be adjusted. Further, by interposing a plurality of gears 350 between the actuator 302 and the support shaft 330, the degree of freedom in arranging the actuator 302 with respect to the throttle plate 110 and the reaction force transmission unit 200 is improved. As a result, a configuration in which the actuator 302, the throttle plate 110, and the reaction force transmission unit 200 are arranged side by side can be adopted. In the exemplary embodiment shown in FIG. 2, the plurality of gears 350 include a pinion gear 352 directly connected to the output shaft 303 of the actuator 302, an output gear 356 directly connected to the support shaft 330, and an intermediate gear 354 provided between the pinion gear 352 and the output gear 356. The intermediate gear 354 has a large-diameter portion 354A that meshes with the pinion gear 352 and a small-diameter portion 354B that axially protrudes from the large-diameter portion 354A.

[0044] In some embodiments, the reaction force applying device 100 includes a position sensor 306 for detecting angle information indicating the angular position of the actuator 302 and outputting a signal indicating the angular position of the actuator 302, as shown in FIG. 2. The angle information detected by the position sensor 306 may be the angular position of the actuator 302 itself or angle information having a correlation with the angular position of the actuator 302. In the example shown in FIG. 2, the position sensor 306 is a sensor for detecting the angular position of the actuator 302 itself, but in other examples, it may be a sensor for detecting the angular position of any of the gears 350 or the intermediate plate 310. Note that a correlation described by a predetermined speed ratio is established between the angular position of the actuator 302 and the angular positions of the respective gears 350 or the intermediate plate 310. The position sensor 306 is disposed on the opposite side of the intermediate plate 310 with the plurality of gears 350 interposed therebetween. In the exemplary embodiment shown in FIG. 2, with respect to the axial direction of the output shaft 303, the position sensor 306 is provided on the opposite side of the intermediate plate 310 with the pinion gear 352 interposed therebetween. Note that the output signal from the position sensor 306 may be input to the ECU 14 and used for calculating the reaction force generation command for the reaction force applying device 100. When calculating the reaction force generation command in the ECU 14, the angular position of the actuator 302 detected by the position sensor 306 may be converted into the angular position of the intermediate plate 310 using the reduction ratios of the plurality of gears 350.

[0045] Hereinafter, a specific example of the reaction force applying device 100 having the above configuration will be described. FIGS. 5A to 6 are diagrams showing a reaction force applying device 100A according to an embodiment. FIG. 5A shows a state where reaction force transmission is blocked during full throttle opening, FIG. 5B shows a state where reaction force transmission is performed during full throttle opening, and FIG. 6 shows a state where reaction force transmission is blocked during full throttle closing. FIGS. 7A to 8 are diagrams showing a reaction force applying device 100B according to an embodiment. FIG. 7A shows a state where reaction force transmission is blocked during full throttle opening, FIG. 7B shows a state where reaction force transmission is performed during full throttle opening, and FIG. 8 shows a state where reaction force transmission is blocked during full throttle closing.

[0046] The reaction force applying device 100A shown in FIGS. 5A to 6 includes a first support member 400 that supports the throttle plate 110, and a second support member 402 that supports the reaction force transmission unit 200 and the reaction force generation unit 300. The first support member 400 and the second support member 402 are not connected and exist independently of each other. The second support member 402 is constituted by a gear box 304 that houses a plurality of gears 350 (see FIG. 2) provided between the actuator 302 and the intermediate plate 310.

[0047] The reaction force applying device 100B shown in FIGS. 7A to 8 includes a first support member 400 that supports the throttle plate 110, a second support member 402 that supports the reaction force transmission unit 200 and the reaction force generation unit 300, and a connecting frame 420 that connects the first support member 400 and the second support member 402. The reaction force applying device 100B includes a first support member 400, which is constituted by a throttle body 410 that houses a throttle valve 404 directly connected to the throttle plate 110. In an exemplary embodiment, the throttle valve 404 is a butterfly valve, and by rotating approximately 90 degrees in the first direction A from the fully open state shown in FIGS. 7A and 7B, it reaches the fully closed state shown in FIG. 8. The throttle position sensor (APS) 12 is disposed on the side opposite to the throttle plate 110 with the throttle valve 404 interposed therebetween in the axial direction along the rotation axis of the throttle valve 404. The second support member 402 is constituted by a gear box 304 that houses a plurality of gears 350 (see FIG. 2) provided between the actuator 302 and the intermediate plate 310.

[0048] In the states shown in FIGS. 5A and 7A, in the reaction force applying device 100 (100A, 100B), the throttle plate 110 is located at the maximum opening position θmax (see FIG. 3), and the first stopper 312 of the intermediate plate 310 is located at the third angular position θ3 (see FIG. 4A). In this state, as described above with reference to FIG. 4A, the convex portion 222 is locked by the first stopper 312. Therefore, the angular position of the rotation plate 210 is held at the first angle θ1, and the rotation plate 210 does not rotate in the first direction A due to the biasing force of the first spring 320. Then, the reaction force applying portion 212 of the rotation plate 210 cannot contact the engaging portion 112 of the throttle plate 110, and a gap g1 is formed between the reaction force applying portion 212 and the engaging portion 112. As a result, the transmission of the reaction force to the throttle plate 110 by the reaction force transmission portion 200 is blocked.

[0049] On the contrary, in the states shown in FIGS. 5B and 7B, as a result of the intermediate plate 310 rotating in the first direction A, the angular position of the first stopper 312 is at an angular position θ'' (see FIG. 4B) on the downstream side of the first direction A from the third angular position θ3. In this state, as described above with reference to FIG. 4B, the rotation plate 210 rotates in the first direction A by the biasing force of the first spring 320 until the reaction force applying portion 212 contacts the engaging portion 112 of the throttle plate 110. At this time, the reaction force applying portion 212 and the engaging portion 112 are in a contact state (a state where there is no gap g1). On the other hand, a gap g2 is formed between the first stopper 312 and the convex portion 222 of the rotation plate 210. As a result, the reaction force applying portion 212 of the rotation plate 210 presses the engaging portion 112 in the first direction A, and the reaction force is transmitted to the throttle plate 110 by the reaction force transmitting portion 200.

[0050] In the states shown in FIGS. 6 and 8, the reaction force applying device 100 (100A, 100B) is such that the throttle plate 110 is located at the minimum opening position θmin (see FIG. 3), and the first stopper 312 of the intermediate plate 310 is located at the third angular position θ3 (see FIG. 4A). In this state, as shown in FIGS. 6 and 8, the convex portion 222 is locked by the first stopper 312. Therefore, the rotation of the rotation plate 210 in the first direction A due to the biasing force of the first spring 320 does not occur. Then, the reaction force applying portion 212 of the rotation plate 210 cannot contact the engaging portion 112 of the throttle plate 110, and a gap g1 is formed between the reaction force applying portion 212 and the engaging portion 112. As a result, the transmission of the reaction force to the throttle plate 110 by the reaction force transmitting portion 200 is blocked.

[0051] In the reaction force applying device 100 (100A, 100B) according to the above-described embodiment, the reaction force input from the reaction force transmitting portion 200 to the throttle plate 110 is transmitted to the throttle grip 10 via the throttle wire 111. Therefore, the restrictions on the arrangement of the reaction force applying device 100 are relaxed, and the degree of freedom in arranging the reaction force applying device 100 can be increased. Hereinafter, with reference to FIG. 9, an arrangement example of the reaction force applying device 100 will be described.

[0052] FIG. 9 is a side view of a vehicle 1 according to an embodiment. As shown in the figure, the vehicle 1 includes a steering system (stem) 30 that supports the steering wheel 3 and the front fork 32, and a frame 40 that covers the engine 20 and its peripheral components. The reaction force applying device 100 may be disposed, for example, inside the steering system 30 or the frame 40. However, since the reaction force applying device 100B shown in FIGS. 7A to 8 is unitized with the throttle device (throttle body 410 and throttle valve 404) via the connection frame 420, the placement location of the reaction force applying device 100B is preferably inside the frame 40 rather than the steering system 30.

[0053] In this specification, expressions indicating relative or absolute arrangements such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric", or "coaxial" not only strictly represent such arrangements, but also represent states in which there are tolerances or relative displacements with angles and distances such that the same function can be obtained. For example, expressions indicating that things such as "identical", "equal", and "homogeneous" are in an equal state not only strictly represent an equal state, but also represent states in which there are tolerances or differences such that the same function can be obtained. Also, in this specification, expressions representing shapes such as a rectangular shape or a cylindrical shape not only represent the shapes of a rectangular shape or a cylindrical shape in a geometrically strict sense, but also represent shapes including concave and convex portions, chamfered portions, etc. within a range where the same effect can be obtained. Also, in this specification, the expressions "comprising", "including", or "having" a component do not exclude the existence of other components.
