[0009] [Embodiment 1] Fig. 1 is a perspective view of a throttle opening detection device 1. Fig. 2 is a right side view of the throttle opening detection device 1. A throttle grip 3 is omitted from Fig. 2. As shown in Fig. 1, the throttle opening detection device 1 is provided on a handlebar 2 equipped on a saddle-ride type vehicle. The throttle opening detection device 1 has a throttle grip 3. The throttle grip 3 is rotatably attached to one end (right end) of the handlebar 2. A brake handle 4 is disposed in front of the throttle grip 3. The brake handle 4 is supported on the handlebar 2 via a master cylinder 5.

[0010] The throttle opening detection device 1 includes a housing 10. The housing 10 is formed in a container shape and has a split structure. The housing 10 includes a second housing 14 disposed on the occupant side and a first housing 12 disposed opposite the second housing 14.

[0011] As shown in FIG. 2 , the first case 12 and the second case 14 each have a flat joint surface M at an open end. In this embodiment, the joint surface M extends in the vertical direction. The joint surfaces M of the first case 12 and the second case 14 abut against each other to form the storage case 10 with a hollow structure. The joint surface M of the first case 12 is formed with a semicircular portion 12A that is recessed forward. The joint surface M of the second case 14 is formed with a semicircular portion 14A that is recessed rearward. The semicircular portion 12A of the first case 12 and the semicircular portion 14A of the second case 14 are arranged opposite each other, thereby forming a circular opening 8 in the storage case 10. The handle 2 is inserted into the opening 8.

[0012] Fig. 3 is a right side view showing the first case 12 and its peripheral components. Fig. 4 is a view taken along the arrow A1 in Fig. 3. The second case 14 is not shown in Figs. 3 and 4. In Fig. 4, a dotted pattern is applied to the inner case 16 for easy identification. The second case 14 is provided with a first switch 50A, a second switch 52A, a third switch 54A, and a fourth switch 56A.

[0013] The first switch 50A includes a first switch body 50C and a first operating portion 50B that is an operator of the first switch body 50C. The first operating portion 50B is operated by an occupant. The first switch body 50C is housed in the second case 14. The first switch body 50C includes an electronic board and is configured as a member that holds the first operating portion 50B.

[0014] The second switch 52A includes a second switch body 52C and a second operating portion 52B that is an operator of the second switch body 52C. The second operating portion 52B is operated by an occupant. The second switch body 52C is housed in the second case 14. The second switch body 52C includes an electronic board and is configured as a member that holds the second operating portion 52B.

[0015] The third switch 54A includes a third switch body 54C and a third operating portion 54B that is an operator of the third switch body 54C. The third operating portion 54B is operated by an occupant. The third switch body 54C is housed in the second case 14. The third switch body 54C includes an electronic board and is configured as a member that holds the third operating portion 54B.

[0016] The fourth switch 56A includes a fourth switch body 56C and a fourth operating part 56B that is an operator of the fourth switch body 56C. The fourth operating part 56B is operated by an occupant. The fourth switch body 56C is housed in the second case 14. The fourth switch body 56C includes an electronic board and is configured as a member that holds the fourth operating part 56B.

[0017] FIG. 5 is a perspective view of the inner case (internal member) 16, and FIG. 6 is a front view of the inner case 16. The inner case 16 is made of resin and is a hollow member. As shown in FIG. 3, the inner case 16 is arranged to cover the periphery of the central axis Ax of the handle 2. The inner case 16 is housed inside the housing case 10. As shown in FIGS. 5 and 6, the inner case 16 includes a connecting portion 22 formed in a substantially cylindrical shape and an overhanging portion (internal housing portion) 18 that integrally overhangs the front side of the connecting portion 22, and a sensor housing portion 20 is disposed on the side of the overhanging portion 18. The handle 2 is inserted into the inner periphery of the connecting portion 22.

[0018] A support portion 26 that protrudes by one step is formed integrally on the side surface of the connecting portion 22 on the handle 2 side. A pair of recessed portions 28A and protruding portions 28B are formed on the support portion 26 at approximately equal intervals in the circumferential direction.

[0019] An interlocking member 32 that moves integrally with the handlebar 2 is disposed inside the inner case 16. The interlocking member 32 has a rotating portion 33 and holding portions 34 connected to both ends of the rotating portion 33. The rotating portion 33 is formed with a generally C-shaped cross section that covers approximately three-quarters of a cylinder with the axis Ax as its center. The interlocking member 32 is connected to the throttle grip 3 via an intermediate portion (not shown). This intermediate portion (not shown) of the throttle grip 3 is inserted into an arc-shaped elongated hole 39 formed in the protrusion 28B of the support portion 26 and is connected to the rotating portion 33 of the interlocking member 32 inside the inner case 16. This allows the interlocking member 32 to rotate in conjunction with the rotation of the throttle grip 3.

[0020] The holding portion 34 of the interlocking member 32 is formed so as to bulge outward in the radial direction of the accommodating case 10 when viewed in the direction of the axis Ax. The radial center of the accommodating case 10 corresponds to the axis Ax, and the radial outer side is away from the axis Ax.

[0021] The holding portion 34 of the interlocking member 32 includes a magnet housing portion 35 and a pin housing portion 36. A magnet 38 is housed in the magnet housing portion 35, and the magnet 38 and a sensor 44 disposed in the sensor housing portion 20 constitute a rotation sensor 46. The sensor housing portion 20 and the sensor 44 are immovable relative to the rotation of the throttle grip 3. The magnet 38 is disposed within the magnet housing portion 35 throughout the entire rotation direction, and can face the sensor housing portion 20 when the holding portion 34 rotates. The rotation sensor 46 detects changes in the magnetic field caused by the rotation of the magnet 38 using the sensor 44, and acquires the rotation state of the throttle grip 3. Detection information from the rotation sensor 46 is input to a control device (not shown).

[0022] A friction pin 40 is accommodated in the pin accommodating portion 36. The friction pin 40, in combination with a biasing member (not shown), is pressed against the inner surface of the protruding portion 18 and the member inside the protruding portion 18. As a result, the friction pin 40 applies resistance to the rotational movement of the throttle grip 3. The friction pin 40 is provided on one side D1 in the rotation direction relative to the magnet 38. More specifically, the friction pin 40 is provided on the wall portion on the other side D2. A plurality of friction pins 40 may be provided.

[0023] The friction pin 40 only needs to provide resistance to the rotation of the throttle grip 3, and therefore the friction resistance of the friction pin 40 and the portion of the protruding portion 18 where the friction pin 40 abuts can be changed as appropriate.

[0024] The throttle grip 3 is supported rotatably on one side D1 and the other side D2 around the axis Ax. When viewed from the apex of the upper part of the throttle grip 3, the one side D1 is the rotation direction in which the throttle grip 3 is tilted toward the occupant, and the other side D2 is the rotation direction in which the throttle grip 3 is tilted away from the occupant.

[0025] In Figure 3, rotating the throttle grip 3 from the initial position C1 to one side D1 increases the power output of the power unit. The position shown by the dashed line in Figure 3 corresponds to the initial position C1 of the holding portion 34, and the position shown by the imaginary line corresponds to the maximum rotation position C2 on the one side D1. Rotating the throttle grip 3 from the initial position C1 to the other side D2 by more than a certain angle cancels the cruise control.

[0026] A spring 42 is disposed on the protruding portion 18, outside the retaining portion 34 and on the other side D2 of the pin accommodating portion 36. The spring 42 applies a reaction force to the rotation of the throttle grip 3 toward the other side D2. When the throttle grip 3 rotates toward the other side D2, the spring 42 abuts against the wall surface of the end of the pin accommodating portion 36 on the other side D2. As a result, when the rider rotates the throttle grip 3 toward the other side D2, the spring 42 applies a reaction force to the rotation.

[0027] 3 and 4 , when viewed from the operation surface, a part of the first operation part 50B and a part of the first switch body 50C overlap with the magnet 38 and the friction pin 40 at the initial position C1. Furthermore, when viewed from the operation surface, a part of the first operation part 50B and a part of the first switch body 50C overlap with the protrusion 18.

[0028] If the protruding portion 18 were to bulge toward the inside of the second case 14, the radial thickness of the second case 14 would increase if the first switch body 50C were arranged so as to overlap the protruding portion 18 in an operating surface view. In this embodiment, the protruding portion 18 is housed in the first case 12, so the first switch body 50C can be arranged close to the inner case 16. This allows the thickness of the second case 14 to be reduced, and the accommodating case 10 to be made compact. Similar to the first switch body 50C, the second switch body 52C, the third switch body 54C, and the fourth switch body 56C can also be housed in the second case 14 close to the protruding portion 18. This allows the thickness of the second case 14 to be reduced, and the accommodating case 10 to be made compact.

[0029] 4, the protrusion 18 and the sensor housing 20 are arranged in this order from the right side, which is the throttle grip 3 side. As shown in FIG. 6, the sensor housing 20 is arranged on the front side within the first case 12. Therefore, even if the switch is arranged so as to overlap with the sensor housing 20 when viewed from the operation surface, the switch can be arranged close to the axis Ax, and the housing case 10 can be made compact.

[0030] A spring 42 is disposed on the protruding portion 18, outside the retaining portion 34 and on the other side D2 of the pin accommodating portion 36. The spring 42 applies a reaction force to rotation of the throttle grip 3 toward the other side D2. When the throttle grip 3 rotates toward the other side D2, the spring 42 abuts against the wall surface of the end of the pin accommodating portion 36 on the other side D2. As a result, when the rider rotates the throttle grip 3 toward the other side D2 from the initial position C1, the spring 42 applies a reaction force to the rotation.

[0031] 3, when the throttle grip 3 moves between the initial position C1 and the maximum rotation position C2, the magnet 38, the sensor 44, and the friction pin 40 are housed in the first case 12. Therefore, when the throttle grip 3 is in either the initial position C1 or the maximum rotation position C2, the magnet 38, the sensor 44, and the friction pin 40 are housed in the first case 12.

[0032] Here, if the joint surface view A1 (see Figure 2) corresponds to the direction viewed from a direction perpendicular to the joint surface M of the second case 14 and the first case 12 and the direction viewed from the second case 14 side, when the second case 14 is in the initial position C1 in the joint surface view A1, the magnet 38 and the spring 42 overlap in that order.

[0033] In addition, when in the initial position C1, the magnet 38 and the spring 42 are arranged so that they are aligned in this order from the radial center of the accommodating case 10 toward the radially outward direction.

[0034] The magnet 38 and the friction pin 40 are arranged so that the rotational path of the magnet 38 about the axis Ax does not overlap with the rotational path of the friction pin 40 .

[0035] The spring 42 is located on an extension of the rotational path of the friction pin 40 with the casing 10 as the center of rotation.

[0036] As described above, according to the first embodiment to which the present invention is applied, the throttle opening detection device 1 includes: a throttle grip 3 that is provided on the handle 2 and is rotatable from an initial position C1 to one direction side D1 and the other direction side D2; a magnet (rotation synchronization member) 38 that rotates together with the throttle grip 3 to obtain the rotational state of the throttle grip 3; a rotation sensor 46 that has a sensor (rotation non-synchronization member) 44 that is immobile with respect to the rotation of the throttle grip 3; a friction pin (rotation resistance force applying member) 40 that rotates together with the throttle grip 3 and applies resistance force to the rotation; and a storage case 10 that is provided on the handle 2 and accommodates the rotation sensor 46 and the friction pin 40. The storage case 10 has a first case 12 and a second case 14. When the throttle grip 3 is in the initial position C1 or at the maximum rotation position C2 on the one direction side D1, the rotation sensor 46 and the friction pin 40 are accommodated in the first case 12.

[0037] According to this configuration, when the throttle grip 3 is between the initial position C1 and the maximum rotation position C2, the rotation sensor 46 and the friction pin 40 are gathered together in the first case 12 corresponding to one side of the storage case 10, thereby eliminating the need to provide a rotational path and rotation space for the magnet 38 that rotates together with the throttle grip 3 in the other second case 14, and as a result the storage case 10 can be made more compact.

[0038] Furthermore, in this embodiment, the rotational path of the magnet 38 with the casing 10 as the center of rotation does not overlap with the rotational path of the friction pin 40 .

[0039] With this configuration, the throttle grip 3 can rotate within the first case 12 while reducing the rotation space in the rotation direction when rotated, making it easier to accommodate the rotation sensor 46 and the friction pin 40 within the first case 12 at both the initial position C1 and the maximum rotation position C2.

[0040] In this embodiment, the friction pin 40 is provided on one side D1 of the rotation direction relative to the magnet 38.

[0041] According to this configuration, a space can be formed on the other side D2 of the magnet 38, and it is expected that the space inside the first case 12 can be used effectively.

[0042] In addition, in this embodiment, the storage case 10 further houses a spring 42 (an other-side rotation reaction force applying member) that applies a reaction force to the rotation of the other side D2 of the throttle grip 3, and the spring 42 is housed in the first case 12.

[0043] This configuration eliminates the need to ensure space in second case 14 for arranging spring 42, thereby enabling a more compact storage case 10. In particular, in this embodiment, friction pin 40 is arranged on one side D1 of magnet 38, and spring 42 is arranged on the other side D2 of magnet 38, thereby enabling effective use of the space in storage case 10, thereby making it easier to make storage case 10 more compact.

[0044] In this embodiment, the spring 42 is located on an extension of the rotational path of the friction pin 40 with the casing 10 as the center of rotation.

[0045] According to this configuration, the friction pin 40 and the spring 42 are on the same rotational path, so the spring 42 can be placed using the space on the rotational path where the friction pin 40 does not move, and the storage case 10 can be made compact in the radial direction.

[0046] In addition, in this embodiment, the storage case 10 is provided with an interlocking member 32 that links the rotational movement of the throttle grip 3 with the rotational movement of the magnet 38 and the friction pin 40, and the interlocking member 32 has a pin storage section 36 (storage section) that stores the friction pin 40, and when the throttle grip 3 rotates toward the other side D2, the end of the pin storage section 36 in the rotational direction comes into contact with the spring 42, causing the spring 42 to apply a reaction force to the rotation of the throttle grip 3 toward the other side D2.

[0047] With this configuration, the pin housing 36 that houses the friction pin 40 also serves as the abutment portion for the spring 42, so that a reaction force can be applied to the rotation of the throttle grip 3 in the other direction D2 without providing any additional components. This reduces the number of parts provided in the housing case 10, allowing the housing case 10 to be made more compact.

[0048] In this embodiment, when the first case 12 is in the initial position C1, the magnet 38 and the spring 42 overlap in this order when viewed from the joining surface.

[0049] According to this configuration, by stacking the magnet 38 and spring 42 in this order when viewed from the joint surface of the first case 12 when in the initial position C1, the magnet 38, which rotates with the rotation of the throttle grip 3, is located radially inward, and the spring 42, which does not rotate with the rotation of the throttle grip 3, is located further radially outward, thereby reducing the rotation range of the magnet 38 and making the storage case 10 more compact.

[0050] In this embodiment, when the accommodating case 10 is in the initial position C1, the magnet 38 and the spring 42 are arranged in this order from the radial center of the accommodating case 10 toward the radially outer side.

[0051] According to this configuration, by stacking the magnet 38 and spring 42 in this order when viewed from the joint surface of the first case 12 when in the initial position C1, the magnet 38, which rotates with the rotation of the throttle grip 3, is located radially inward, and the spring 42, which does not rotate with the rotation of the throttle grip 3, is located further radially outward, thereby reducing the rotation range of the magnet 38 and making the storage case 10 more compact.

[0052] In addition, in this embodiment, the storage case 10 is provided with a first switch 50A (switch) through which an occupant of the saddle-ride type vehicle performs an input, and the first switch 50A has a first switch main body 50C (switch main body) and a first operating unit 50B (operating unit) operated by the occupant, and the first switch 50A is provided in the second case 14, and when viewed from the operating surface, at least a portion of the first operating unit 50B and at least a portion of the first switch main body 50C overlap with at least one of the magnet 38 and the spring 42.

[0053] With this configuration, the first operating part 50B can be moved closer to the axis Ax of the handle 2 while suppressing the expansion of the storage case 10 in the width direction (axial direction of the axis Ax). This makes it possible to make the storage case 10 more compact while also improving the operability of the first switch 50A, second switch 52A, third switch 54A, and fourth switch 56A by the driver (occupant).

[0054] In addition, in this embodiment, the storage case 10 has a protrusion 18 that houses the magnet 38 and the spring 42, and when viewed from the operating surface, at least a portion of the first operating unit 50B, the second operating unit 52B, the third operating unit 54B, and the fourth operating unit 56B and at least a portion of the first switch body 50C, the second switch body 52C, the third switch body 54C, and the fourth switch body 56C overlap with the protrusion 18.

[0055] With this configuration, the first operating part 50B can be moved closer to the axis Ax of the handle 2 while suppressing the expansion of the storage case 10 in the width direction (axial direction of the axis Ax). This makes it possible to make the storage case 10 more compact while also improving the operability of the first switch 50A, the second switch 52A, the third switch 54A, and the fourth switch 56A by the driver.

[0056] [Embodiment 2] A second embodiment of the present invention will be described below. In this embodiment 2, parts configured in the same manner as in the first embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0057] Fig. 7 is a perspective view of a throttle opening detection device 100 according to a second embodiment, which is provided on a handlebar 2. Fig. 8 is a right side view of the throttle opening detection device 100. The throttle grip 3 is omitted from Fig. 8. Fig. 9 is a side plan view showing the first case 112 and its peripheral members. The second case 114 is omitted from the illustration. Fig. 10 is a plan view of the storage case 110. Fig. 10 is a plan view seen from the joint surface, and the second case 114 is omitted from the illustration. In Fig. 10, a dot pattern is applied to the inner case 16 to make it easier to distinguish.

[0058] 7 and 10, the accommodating case 110 includes a first case 112 and a second case 114. The accommodating case 110 is formed to have a larger width in the direction of the axis Ax than the accommodating case 10 according to the first embodiment.

[0059] 7 to 10, the first switch 150A includes a first switch body 150C and a first operating unit 50B that is an operator of the first switch body 150C. The first operating unit 150B is operated by an occupant. The first switch body 150C is housed in the second case 14. The first switch body 150C includes an electronic board and is configured as a member that holds the first operating unit 150B.

[0060] The second switch 152A, the third switch 154A, and the fourth switch 156A respectively include a second switch body 152C, a third switch body 154C, and a fourth switch body 156C. The second switch 152A, the third switch 154A, and the fourth switch 156A respectively include a second operating portion 152B, a third operating portion 154B, and a fourth operating portion 156B.

[0061] The second operating unit 152B, the third operating unit 154B, and the fourth operating unit 156B are operated by the occupant. The second switch body 152C, the third switch body 154C, and the fourth switch body 156C are housed in the second case 14. The second switch body 152C, the third switch body 154C, and the fourth switch body 156C each include an electronic board and are configured as members that hold the second operating unit 152B, the third operating unit 154B, and the fourth operating unit 156B, and further include an electronic board.

[0062] 10 , in the operation surface view, the first switch body 150C and the second switch body 152C are arranged so as not to overlap with the magnet 38 and the friction pin 40 when in the initial position C1. Furthermore, in the operation surface view, the first switch body 150C and the second switch body 152C are arranged so as not to overlap with the protruding portion 18. In FIG. 10 , parts of the first switch body 150C and the second switch body 152C are indicated by dashed lines.

[0063] Further, when viewed from the operation surface, the first operating portion 150B is disposed so that a portion of the first operating portion 150B overlaps with the protruding portion 18.

[0064] As shown in Fig. 10 , the first switch body 150C and the second switch body 152C are arranged so as not to overlap with the protruding portion 18 when viewed from the operation surface, and therefore, as shown in Fig. 9 , the first switch body 150C and the second switch body 152C can be arranged so as to overlap with the protruding portion 18 when viewed in the direction of the axis Ax. Furthermore, when viewed in the direction of the axis Ax, the lower end 150D of the first switch body 150C and the lower end 152D of the second switch body 152C are arranged more inward than the edge of the connecting portion 22 of the protruding portion 18. This allows the radial dimension of the accommodating case 110 to be made compact.

[0065] As described above, in this embodiment to which the present invention is applied, the storage case 110 is provided with a first switch 150A and a second switch 152A through which an occupant of the saddle-ride type vehicle performs inputs, and the first switch 150A and the second switch 152A respectively have a first switch body 150C and a second switch body 152C, and a first operating unit 150B and a second operating unit 152B operated by the occupant, and the first switch 150A and the second switch 152A are provided in the second case 114, and when viewed from the operating surface, at least a portion of the first operating unit 150B overlaps with at least one of the magnet 38 and the friction pin 40, and the first switch body 150C and the second switch body 152C do not overlap with the magnet 38, the friction pin 40, or the spring 42.

[0066] With this configuration, the first operating part 150B can be moved closer to the axis Ax of the handle 2 while suppressing the radial expansion of the storage case 110, thereby making it possible to make the storage case 110 more compact while also improving the operability of the first switch 150A by the occupant.

[0067] In addition, in this embodiment, the storage case 110 has a protrusion 18 that houses the magnet 38 and the friction pin 40, and when viewed from the operating surface, at least a portion of the first operating part 150B overlaps with the protrusion 18, and the first switch body 150C and the second switch body 152C do not overlap with the protrusion 18.

[0068] According to this configuration, the first operating part 150B can be moved closer to the axis Ax of the steering wheel 2 while suppressing radial expansion of the accommodating case 110, thereby improving the operability of the first switch 150A by the occupant while making the accommodating case 110 more compact.

[0070] The second case 14, 114 included in the housing case 10, 110 shown in Figures 1 and 7 may be located on the occupant side and may be tilted toward one direction D1 or the other direction D2. The housing case 10, 110 may be arranged so that the joint surface M is tilted in either the front or rear direction. As shown in Figures 4 to 6 and 10, the protruding portion 18 and the sensor housing portion 20 that constitute the inner case 16 are integrally formed, but the protruding portion 18 and the sensor housing portion 20 may also be formed and arranged as separate bodies. The power unit may be an internal combustion engine or an electric motor.

[0071] [Configurations Supported by the Above-described Embodiments] The above-described embodiments support the following configurations.

[0072] (Configuration 1) A throttle opening detection device for a saddle-ride type vehicle, comprising: a throttle grip attached to a handle and rotatable in one direction and the other direction from an initial position; a rotation sensor having a rotation synchronization member that rotates with the throttle grip to obtain the rotation state of the throttle grip and a rotation non-synchronization member that is immovable relative to the rotation of the throttle grip; a rotation resistance force applying member that rotates with the throttle grip and applies resistance to the rotation; and a storage case attached to the handle and accommodating the rotation sensor and the rotation resistance force applying member, wherein the storage case has a first case and a second case, and the rotation sensor and the rotation resistance force applying member are accommodated in the first case when the throttle grip is in the initial position and at the maximum rotation position in one direction. With this configuration, the rotation sensor and the rotation resistance force applying member are housed in the first case, leaving excess space on the second case side, and by adding a switch or the like to this excess space, the housing case can be made more compact.

[0073] (Configuration 2) The throttle opening detection device according to Configuration 1, wherein the rotation path of the rotation synchronization member, with the housing case as the rotation center, does not overlap with the rotation path of the rotation resistance force applying member. With this configuration, the rotation space in the rotation direction when the throttle grip is rotated can be reduced, making it easier to rotate within the first case, and the rotation sensor and the rotation resistance force applying member can be more easily accommodated within the first case.

[0074] (Configuration 3) The throttle opening detection device according to Configuration 1 or 2, wherein the rotation resistance force applying member is provided on the one side in the rotation direction of the rotation synchronization member. With this configuration, space can be created on the other side of the rotation synchronization member, which is expected to result in effective use of space.

[0075] (Configuration 4) The throttle opening detection device according to Configuration 1, wherein the accommodating case further accommodates a counter-rotation reaction force applying member that applies a reaction force to rotation of the throttle grip in the other direction, and the counter-rotation reaction force applying member is accommodated in the first case. With this configuration, there is no need to ensure space in the second case for the counter-rotation reaction force applying member, and as a result, the accommodating case can be made compact.

[0076] (Configuration 5) A throttle opening detection device according to Configuration 4, characterized in that the other-side rotation reaction force adding member is located on an extension of the rotation path of the rotation resistance force adding member, with the casing as the rotation center. With this configuration, the rotation resistance force adding member and the other-side rotation reaction force adding member are on the same rotation path, so the other-side rotation reaction force adding member can be disposed using the space on the rotation path where the rotation resistance force adding member does not move, and the casing can be made more compact in the radial direction.

[0077] (Configuration 6) The throttle opening detection device according to Configuration 4 or 5, characterized in that the accommodating case includes an interlocking member that interlocks the rotation of the throttle grip with the rotation of the rotation synchronization member and the rotation resistance force applying member, the interlocking member having a housing portion that houses the rotation resistance force applying member, and when the throttle grip rotates in the other direction, the end of the housing portion in the rotation direction abuts against the other-side rotation reaction force applying member, causing the other-side rotation reaction force applying member to apply a reaction force to the rotation of the throttle grip in the other direction. According to this configuration, the housing portion that houses the rotation resistance force applying member also serves as the abutment portion for the other-side rotation reaction force applying member, thereby applying a reaction force to the rotation of the throttle grip in the other direction without providing an additional component. This makes it easier to reduce the number of parts required in the accommodating case, making the accommodating case more compact.

[0078] (Configuration 7) The throttle opening detection device according to Configuration 4 or 5, wherein, when the first case is in the initial position, the rotation synchronization member and the other-side rotation reaction force adding member overlap in this order when viewed from the joint surface of the first case. According to this configuration, when the first case is in the initial position, the rotation synchronization member and the other-side rotation reaction force adding member overlap in this order when viewed from the joint surface of the first case, and by locating the rotating rotation synchronization member radially inward, the rotation range of the rotation synchronization member can be reduced, allowing the storage case to be made more compact.

[0079] (Configuration 8) The throttle opening detection device according to Configuration 4 or 5, characterized in that, when in the initial position, the rotation synchronization member and the other-side rotation reaction force adding member are arranged in this order from the radial center of the accommodating case toward the radially outward direction. According to this configuration, by overlapping the rotation synchronization member and the other-side rotation reaction force adding member in this order when viewed from the joint surface of the first case when in the initial position, the rotation synchronization member is provided radially inward, thereby reducing the rotation range of the rotation synchronization member and making the accommodating case more compact.

[0080] (Configuration 9) The throttle opening detection device according to any one of Configurations 1, 2, and 4, wherein the storage case is provided with a switch that is input by a passenger of the saddle-ride type vehicle, the switch having a switch body and an operating unit operated by the passenger, the switch being provided in the second case, and in an operating surface view of the switch, at least a portion of the operating unit and at least a portion of the switch body overlap with at least one of the rotation synchronizing member and the rotation resistance force applying member. With this configuration, the operating unit can be moved closer to the axis of the handlebars 2 while suppressing the expansion of the storage case in the width direction, thereby making it possible to make the storage case more compact and improving the operability of the switch by the driver (passenger).

[0081] (Configuration 10) The throttle opening detection device according to Configuration 9, wherein the accommodating case has an internal accommodating section that accommodates the rotation synchronizing member and the rotation resistance force applying member, and when viewed from the operating surface of the switch, at least a part of the operating section and at least a part of the switch body overlap with the internal accommodating section. With this configuration, the operating section can be moved closer to the axis of the steering wheel while suppressing the expansion of the accommodating case in the width direction, thereby making it possible to make the accommodating case more compact and improving the operability of the switch by the driver.

[0082] (Configuration 11) The throttle opening detection device according to Configuration 4 or 5, wherein the accommodating case is provided with a switch for input by a passenger of the saddle-ride type vehicle, the switch having a switch body and an operating portion operated by the passenger, the switch being provided in the second case, and in an operating surface view of the switch, at least a portion of the operating portion overlaps with at least one of the rotation synchronization member and the rotation resistance force applying member, and the switch body does not overlap with the rotation synchronization member, the rotation resistance force applying member, or the other rotation reaction force applying member. With this configuration, the operating portion can be moved closer to the axis of the handlebar while suppressing radial expansion of the accommodating case, thereby making it possible to make the accommodating case more compact and improving operability of the switch by the passenger.

[0083] (Configuration 12) The throttle opening detection device according to Configuration 11, wherein the housing case has an internal housing portion that houses the rotation synchronization member and the rotation resistance force applying member, and when viewed from the operating surface of the switch, at least a portion of the operating portion overlaps the internal housing portion, but the switch main body does not overlap the internal housing portion. With this configuration, the operating portion can be positioned closer to the axis of the steering wheel while suppressing radial expansion of the housing case, thereby improving operability of the switch by the occupant while making the housing case more compact. Furthermore, since the switch main body can be positioned closer to the axis of the steering wheel, the operability of the switch by the occupant can be improved while making the housing case more compact.
