以下、本発明の実施形態について図面を参照しながら具体的に説明する。
本実施形態に係るスロットルグリップ装置は、図１に示すように、二輪車のハンドルバーＨに取り付けられたスロットルグリップＧの回転角度を検出し、その検出信号を二輪車が搭載するＥＣＵ等電子制御装置に送るためのもので、図２〜８に示すように、スロットルグリップＧと、ケース１と、連動部材２と、付勢力付与手段３と、第１付勢手段４と、第２付勢手段５と、回転部材６と、磁気センサ７（回転角度検出手段）と、押圧手段１０と、カバー部材としてのハンドルスイッチケースＳとを有して構成されている。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 1, the throttle grip device according to the present embodiment detects the rotation angle of the throttle grip G attached to the handlebar H of the motorcycle, and sends the detection signal to an electronic control device such as an ECU mounted on the motorcycle. For feeding, as shown in FIGS. 2 to 8, the throttle grip G, the case 1, the interlocking member 2, the urging force applying means 3, the first urging means 4, and the second urging means 5 are used. , A rotating member 6, a magnetic sensor 7 (rotation angle detecting means), a pressing means 10, and a handle switch case S as a cover member.

ケース１は、二輪車（車両）のハンドルバーＨの先端側（スロットルグリップＧの基端側）に取り付けられたハンドルスイッチケースＳ内に配設されたもので、本スロットルグリップ装置を構成する各種部品を収容するとともに、連動部材２、付勢力付与手段３及び回転部材６等を回転自在に保持するものである。また、符号９は、ケース１の開口側を塞ぐための蓋部材を示している。 The case 1 is arranged in the handle switch case S attached to the tip side (base end side of the throttle grip G) of the handlebar H of the motorcycle (vehicle), and is various parts constituting the throttle grip device. The interlocking member 2, the urging force applying means 3, the rotating member 6, and the like are rotatably held. Further, reference numeral 9 indicates a lid member for closing the opening side of the case 1.

スロットルグリップＧは、ハンドルスイッチケースＳから延設されるとともに、運転者が把持しつつ回転操作が可能とされたもので、図１、２に示すように、初期位置から軸回りに所定方向の正回転ａ及び当該所定方向とは逆方向の逆回転ｂが可能とされている。かかるスロットルグリップＧの基端部には、図２に示すように、一対の突出部から成る係合部Ｇａと、鍔部Ｇｂとが形成されており、係合部Ｇａが連動部材２の被係合部２ａ（図２等参照）に係合することにより、スロットルグリップＧと連動部材２とが連結されるようになっている。さらに、鍔部Ｇｂは、スロットルグリップＧの基端部において周方向全域に亘って一体形成された部位から成る。 The throttle grip G is extended from the handle switch case S and can be rotated while being gripped by the driver. As shown in FIGS. 1 and 2, the throttle grip G is axially oriented in a predetermined direction from the initial position. The forward rotation a and the reverse rotation b in the direction opposite to the predetermined direction are possible. As shown in FIG. 2, an engaging portion Ga composed of a pair of protruding portions and a flange portion Gb are formed at the base end portion of the throttle grip G, and the engaging portion Ga is covered with the interlocking member 2. By engaging with the engaging portion 2a (see FIG. 2 and the like), the throttle grip G and the interlocking member 2 are connected to each other. Further, the flange portion Gb is composed of a portion integrally formed at the base end portion of the throttle grip G over the entire circumferential direction.

連動部材２は、スロットルグリップＧに形成された係合部Ｇａと係合し得る被係合部２ａを有するとともに、当該スロットルグリップＧの正回転ａ及び逆回転ｂに連動して回転し得るものである。具体的には、本実施形態に係る連動部材２は、図１０に示すように、一対の被係合部２ａと、一対の収容部２ｂと、フランジ２ｃと、ギア２ｄとを有した円環状部材から成る。 The interlocking member 2 has an engaged portion 2a that can engage with the engaging portion Ga formed on the throttle grip G, and can rotate in conjunction with the forward rotation a and the reverse rotation b of the throttle grip G. Is. Specifically, as shown in FIG. 10, the interlocking member 2 according to the present embodiment has an annular shape having a pair of engaged portions 2a, a pair of accommodating portions 2b, a flange 2c, and a gear 2d. It consists of members.

被係合部２ａは、スロットルグリップＧの係合部Ｇａと対応した位置にそれぞれ形成された凹形状から成り、当該被係合部２ａに係合部Ｇａが嵌入して係合した状態で連動部材２にスロットルグリップＧの基端側が接続されている。これにより、スロットルグリップＧの回転に伴って連動部材２も回転し得るようになっている。かかる被係合部２ａは、連動部材２の表面（ケース１に組み付けられた際、外部に臨ませ得る一方の面）に形成されるとともに、他方の面には、収容部２ｂが形成されている。なお、連動部材２における他方の面には、円弧状にそれぞれ形成された一対の凸部２ｅが形成されている。 The engaged portion 2a has a concave shape formed at a position corresponding to the engaging portion Ga of the throttle grip G, and is interlocked in a state where the engaging portion Ga is fitted and engaged with the engaged portion 2a. The base end side of the throttle grip G is connected to the member 2. As a result, the interlocking member 2 can also rotate with the rotation of the throttle grip G. The engaged portion 2a is formed on the surface of the interlocking member 2 (one surface that can face the outside when assembled to the case 1), and the accommodating portion 2b is formed on the other surface. There is. A pair of convex portions 2e formed in an arc shape are formed on the other surface of the interlocking member 2.

収容部２ｂは、一対の被係合部２ａの間の位置に弧状に形成された溝形状から成り、その内部には第２付勢手段５を構成する圧縮コイルスプリングがそれぞれ収容可能とされている。フランジ２ｃは、連動部材２の全周方向に亘り径方向に向かって突出形成されるとともに、所定範囲に亘ってギア２ｄが形成されている。このギア２ｄは、回転部材６の外周に形成されたギアと噛み合うことが可能とされており、連動部材２の回転に伴って回転部材６が回転するようになっている。 The accommodating portion 2b has a groove shape formed in an arc shape at a position between the pair of engaged portions 2a, and the compression coil springs constituting the second urging means 5 can be accommodated therein. There is. The flange 2c is formed so as to project in the radial direction over the entire circumferential direction of the interlocking member 2, and the gear 2d is formed over a predetermined range. The gear 2d can mesh with a gear formed on the outer circumference of the rotating member 6, and the rotating member 6 rotates with the rotation of the interlocking member 2.

回転部材６は、上述のように連動部材２と連動して回転し得るもので、ケース１の所定位置に形成された収容凹部１ｃ（図９参照）に収容されるとともに、軸Ｌ（図６、８参照）を中心として回転自在とされている。しかして、連動部材２が回転すると、その回転角度に応じた回転角度にて回転部材６が回転するようになっている。かかる回転部材６には、磁石ｍが取り付けられており、当該回転部材６の回転に伴って磁石ｍから生じる磁力が変化するよう構成されている。 The rotating member 6 can rotate in conjunction with the interlocking member 2 as described above, and is accommodated in the accommodating recess 1c (see FIG. 9) formed at a predetermined position of the case 1 and the shaft L (FIG. 6). , 8), and it is rotatable around the center. Therefore, when the interlocking member 2 rotates, the rotating member 6 rotates at a rotation angle corresponding to the rotation angle. A magnet m is attached to the rotating member 6, and the magnetic force generated from the magnet m changes with the rotation of the rotating member 6.

磁気センサ７（回転角度検出手段）は、図６に示すように、回転部材６の軸Ｌの延長線上の位置に配設されたセンサから成り、回転部材６に取り付けられた磁石ｍから生じる磁気の変化を検出することにより、スロットルグリップＧの回転角度を検出可能とされている。具体的には、磁気センサ７は、磁石ｍの磁場変化（磁束密度の変化）に応じた出力電圧を得ることができるもので、例えばホール効果を利用した磁気センサであるホール素子（具体的には、磁石ｍの磁場（磁束密度）に比例した出力電圧を得ることができるリニアホールＩＣ）等により構成されている。なお、本実施形態に係る磁気センサ７は、所定の電気回路が印刷されたプリント基板８に形成されている。 As shown in FIG. 6, the magnetic sensor 7 (rotation angle detecting means) is composed of a sensor arranged at a position on an extension line of the axis L of the rotating member 6, and the magnetism generated from the magnet m attached to the rotating member 6. It is possible to detect the rotation angle of the throttle grip G by detecting the change in. Specifically, the magnetic sensor 7 can obtain an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m. For example, a Hall element (specifically, a Hall element) which is a magnetic sensor utilizing the Hall effect. Is composed of a linear Hall IC) or the like that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m. The magnetic sensor 7 according to the present embodiment is formed on a printed circuit board 8 on which a predetermined electric circuit is printed.

しかして、スロットルグリップＧが正回転ａするのに伴って連動部材２が同方向に回転すると、回転部材６も連動して回転し、当該回転部材６に取り付けられた磁石ｍも同方向に同一角度だけ回転する。これにより、その回転角度によって磁場が変化するので、当該回転角度に応じた出力電圧を得ることができ、当該出力電圧に基づき連動部材２の回転角度（即ち、スロットルグリップＧの回転角度）を検出することが可能とされている。このように検出されたスロットルグリップＧの回転角度は、二輪車に搭載されたＥＣＵ（エンジン・コントロール・ユニット）に対して電気信号として送信され、送信されたスロットルグリップＧの回転角度に応じて車両のエンジンが制御され得るようになっている。 Then, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates in the forward direction a, the rotating member 6 also rotates in conjunction with the rotating member 6, and the magnet m attached to the rotating member 6 also rotates in the same direction. Rotate by an angle. As a result, since the magnetic field changes depending on the rotation angle, an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 2 (that is, the rotation angle of the throttle grip G) is detected based on the output voltage. It is possible to do. The rotation angle of the throttle grip G detected in this way is transmitted as an electric signal to the ECU (engine control unit) mounted on the motorcycle, and the rotation angle of the throttle grip G is transmitted according to the rotation angle of the vehicle. The engine can be controlled.

一方、スロットルグリップＧが逆回転ｂするのに伴って連動部材が同方向に回転すると、回転部材６も連動して回転し、当該回転部材６に取り付けられた磁石ｍも同方向に同一角度だけ回転する。これにより、その回転角度によって磁場が変化するので、当該回転角度に応じた出力電圧を得ることができ、スロットルグリップＧの逆回転ｂを検出することができる。 On the other hand, when the interlocking member rotates in the same direction as the throttle grip G rotates in the reverse direction b, the rotating member 6 also rotates in conjunction with each other, and the magnet m attached to the rotating member 6 also rotates in the same direction by the same angle. Rotate. As a result, since the magnetic field changes depending on the rotation angle, an output voltage corresponding to the rotation angle can be obtained, and the reverse rotation b of the throttle grip G can be detected.

このように、スロットルグリップＧの逆回転ｂが検出されると、二輪車が具備する所定の機能を作動又は非作動とすることができるようになっている。本実施形態においては、走行速度を一定に保持する定車速保持装置（オートクルーズ装置）を備えた二輪車に適用されており、スロットルグリップＧを逆回転ｂ（初期位置からスロットルを全開させる正回転ａの方向とは逆方向の回転操作）させると、当該定車速の保持制御を停止（キャンセル）させ得るよう構成されている。 In this way, when the reverse rotation b of the throttle grip G is detected, it is possible to activate or deactivate a predetermined function provided by the motorcycle. In the present embodiment, it is applied to a two-wheeled vehicle provided with a constant vehicle speed holding device (auto cruise device) that keeps the traveling speed constant, and the throttle grip G is rotated in the reverse direction b (forward rotation a that fully opens the throttle from the initial position). It is configured so that the holding control of the constant vehicle speed can be stopped (cancelled) by rotating the vehicle in the direction opposite to the direction of.

しかして、本実施形態に係る連動部材２は、スロットルグリップＧの回転力を回転部材６に伝達するためのギア２ｄが形成された伝達手段を構成するとともに、その内部（本実施形態においては収容部２ｂ内）に第２付勢手段５が収容されており、連動部材２がスロットルグリップＧの回転力を伝達する機能と、第２付勢手段５を収容する機能とを併せて持つものとされている。 Thus, the interlocking member 2 according to the present embodiment constitutes a transmission means in which a gear 2d for transmitting the rotational force of the throttle grip G to the rotating member 6 is formed, and is housed inside the interlocking member 2 (in the present embodiment). The second urging means 5 is housed in the portion 2b), and the interlocking member 2 has a function of transmitting the rotational force of the throttle grip G and a function of accommodating the second urging means 5. Has been done.

また、本実施形態に係る連動部材２は、ギア２ｄが所定範囲に亘って形成されたフランジ２ｃを有するとともに、図９〜１１に示すように、ストッパ１ａ及び当該ストッパ１ａと当接する付勢力付与手段３の当接部３ｃが凸部２ｅに対応する位置に形成されている。これにより、ストッパ１ａ及び当接部３ｃを連動部材２のフランジ２ｃの径内に収めることができ、小型化に寄与することができる。 Further, the interlocking member 2 according to the present embodiment has a flange 2c in which the gear 2d is formed over a predetermined range, and as shown in FIGS. 9 to 11, a stopper 1a and an urging force that abuts on the stopper 1a are applied. The contact portion 3c of the means 3 is formed at a position corresponding to the convex portion 2e. As a result, the stopper 1a and the contact portion 3c can be accommodated within the diameter of the flange 2c of the interlocking member 2, which can contribute to miniaturization.

第１付勢手段４は、捩りコイルバネから成り、スロットルグリップＧが正回転ａしたとき、連動部材２を初期位置に向かって付勢するためのものである。すなわち、スロットルグリップＧを正回転ａさせると、第１付勢手段４の付勢力に抗して連動部材２が回転するので、その付勢力がスロットルグリップＧに伝わり、スロットルグリップＧを初期位置に戻す力が作用するのである。 The first urging means 4 is composed of a torsion coil spring, and is for urging the interlocking member 2 toward the initial position when the throttle grip G rotates in the forward direction a. That is, when the throttle grip G is rotated in the forward direction a, the interlocking member 2 rotates against the urging force of the first urging means 4, so that urging force is transmitted to the throttle grip G and the throttle grip G is set to the initial position. The force to return acts.

第２付勢手段５は、一対のコイルスプリングから成り、スロットルグリップＧが逆回転ｂしたとき、連動部材２を初期位置に向かって付勢するためのものである。すなわち、スロットルグリップＧを逆回転ｂさせると、第２付勢手段５の付勢力に抗して連動部材２が回転するので、その付勢力がスロットルグリップＧに伝わり、スロットルグリップＧを初期位置に戻す力が作用するのである。 The second urging means 5 is composed of a pair of coil springs, and is for urging the interlocking member 2 toward the initial position when the throttle grip G rotates in the reverse direction b. That is, when the throttle grip G is rotated in the reverse direction b, the interlocking member 2 rotates against the urging force of the second urging means 5, so that urging force is transmitted to the throttle grip G and the throttle grip G is set to the initial position. The force to return acts.

付勢力付与手段３は、第２付勢手段５が取り付けられ、スロットルグリップＧが正回転ａしたとき、第２付勢手段５の付勢力を連動部材２に付与させず（このとき、第１付勢手段４の付勢力のみが連動部材に付与される）、スロットルグリップＧが逆回転ｂしたとき、第２付勢手段５の付勢力を連動部材２に付与し得るものである。具体的には、付勢力付与手段３は、図１１に示すように、一対の突出部３ａと、第２付勢手段５の一端５ａ側を受けるための一対のバネ受け３ｂと、当接部３ｃとを有した円環状部材から成る。 When the second urging means 5 is attached and the throttle grip G rotates forward a, the urging force applying means 3 does not apply the urging force of the second urging means 5 to the interlocking member 2 (at this time, the first urging force applying means 3). Only the urging force of the urging means 4 is applied to the interlocking member), and when the throttle grip G rotates in the reverse direction b, the urging force of the second urging means 5 can be applied to the interlocking member 2. Specifically, as shown in FIG. 11, the urging force applying means 3 includes a pair of projecting portions 3a, a pair of spring receivers 3b for receiving one end 5a side of the second urging means 5, and a contact portion. It is composed of an annular member having 3c.

一対の突出部３ａのうち一方には、外径方向にさらに突出した当接部３ｃが形成されている。そして、連動部材２に付勢力付与手段３が組み付けられた状態において、図１８に示すように、当接部３ｃが一対の凸部２ｅが形成された間隙（一方の凸部２ｅの端部２ｅａと他方の凸部２ｅの端部２ｅｂとの間）に位置するとともに、連動部材２が正回転ａすると、図１９に示すように、凸部２ｅの端部２ｅａが当接部３ｃの一方の端面３ｃａを押圧し、連動部材２と共に付勢力付与手段３が回転するようになっている。一方、連動部材２が逆回転ｂすると、図２０に示すように、他方の凸部２ｅの端部２ｅｂが当接部３ｃの他方の端面３ｃｂに当接するまで回転するものの、その当接するまでの間、他方の端面３ｃａを押圧しないので、連動部材２の回転を許容しつつ付勢力付与手段３は停止した状態とされる。 One of the pair of protruding portions 3a is formed with a contact portion 3c that further protrudes in the outer diameter direction. Then, in a state where the urging force applying means 3 is assembled to the interlocking member 2, as shown in FIG. 18, a gap in which a pair of convex portions 2e are formed by the contact portions 3c (the end portion 2ea of one convex portion 2e). When the interlocking member 2 rotates forward a while being located between the convex portion 2e and the end portion 2eb of the other convex portion 2e, the end portion 2ea of the convex portion 2e becomes one of the contact portions 3c as shown in FIG. By pressing the end surface 3ca, the urging force applying means 3 rotates together with the interlocking member 2. On the other hand, when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. 20, the end portion 2eb of the other convex portion 2e rotates until it abuts on the other end surface 3cc of the abutting portion 3c, but until it abuts. Since the other end surface 3ca is not pressed during the period, the urging force applying means 3 is stopped while allowing the interlocking member 2 to rotate.

バネ受け３ｂは、連動部材２に付勢力付与手段３を取り付けた状態において、当該連動部材２の収容部２ｂ内に位置するもので、図７に示すように、収容部２ｂ内に収容された第２付勢手段５の一端５ａ側を受け得るものである。なお、第２付勢手段５は、一端５ａがバネ受け３ｂにて支持されるとともに、他端５ｂ側が押圧手段１０の壁面１０ｃに当接して組み付けられており、連動部材２と付勢力付与手段３とが共に回転したとき（図１９参照）、第２付勢手段５による付勢力は作用せず、連動部材２が回転しつつ付勢力付与手段３が停止したとき（図２０参照）、第２付勢手段５が圧縮されて付勢力が連動部材２に付与されるよう構成されている。 The spring receiver 3b is located in the accommodating portion 2b of the interlocking member 2 in a state where the urging force applying means 3 is attached to the interlocking member 2, and is accommodated in the accommodating portion 2b as shown in FIG. One end 5a side of the second urging means 5 can be received. The second urging means 5 is assembled so that one end 5a is supported by the spring receiver 3b and the other end 5b side is in contact with the wall surface 10c of the pressing means 10, and the interlocking member 2 and the urging force applying means 5 are assembled. When the urging force 3 and the urging force 3 are rotated together (see FIG. 19), the urging force by the second urging means 5 does not act, and when the interlocking member 2 is rotating and the urging force applying means 3 is stopped (see FIG. 20), the first 2 The urging means 5 is compressed and the urging force is applied to the interlocking member 2.

さらに、当接部３ｃは、付勢力付与手段３の径方向に向かって一体的に突出形成された部位から成り、連動部材２が逆回転ｂする際、図２０に示すように、ケース１に形成されたストッパ１ａと当接し得るようになっている。これにより、連動部材２が逆回転ｂして第２付勢手段５の付勢力による反力を受けたとしても、付勢力付与手段３の停止状態が保持されるようになっている。 Further, the contact portion 3c is composed of a portion integrally projected in the radial direction of the urging force applying means 3, and when the interlocking member 2 rotates in the reverse direction b, the contact portion 3c is formed in the case 1 as shown in FIG. It can come into contact with the formed stopper 1a. As a result, even if the interlocking member 2 rotates in the reverse direction b and receives a reaction force due to the urging force of the second urging means 5, the stopped state of the urging force applying means 3 is maintained.

ところで、第１付勢手段４は、一端４ａが連動部材２に形成された凸部２ｅの端部２ｅｃ（図１０参照）に係止されるとともに、他端４ｂがケース１に形成された係止溝１ｂ（図８参照）に係止されており、連動部材２が正回転ａして付勢力付与手段３と共に回転すると、図１９に示すように、一端４ａが凸部２ｅの端部２ｅｃに押圧され、これら連動部材２及び付勢力付与手段３に対して付勢力を付与し得るよう構成されている。一方、連動部材２が逆回転ｂすると、図２０に示すように、第１付勢手段４の一端４ａは、凸部２ｅの間（一方の凸部２ｅの端部２ｅｄと他方の凸部２ｅの端部２ｅｃとの間）に位置した状態が保持されて押圧されず、当該第１付勢手段４の付勢力は付与されないようになっている。 By the way, in the first urging means 4, one end 4a is locked to the end 2ec (see FIG. 10) of the convex portion 2e formed on the interlocking member 2, and the other end 4b is formed in the case 1. It is locked to the stop groove 1b (see FIG. 8), and when the interlocking member 2 rotates in the forward direction a and rotates together with the urging force applying means 3, one end 4a becomes the end 2ec of the convex portion 2e as shown in FIG. It is configured to be able to apply urging force to the interlocking member 2 and the urging force applying means 3. On the other hand, when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. 20, one end 4a of the first urging means 4 is between the convex portions 2e (the end portion 2ed of one convex portion 2e and the other convex portion 2e). The state of being located (between the end 2 ec) is held and not pressed, and the urging force of the first urging means 4 is not applied.

このように、本実施形態に係る付勢力付与手段３は、第２付勢手段５が取り付けられ、スロットルグリップＧが正回転ａしたとき、連動部材２と共に回転して第２付勢手段５の付勢力を当該連動部材２に付与せず（第１付勢手段４の付勢力は付与される）、スロットルグリップＧが逆回転ｂしたとき、連動部材２の回転を許容しつつケース１に形成されたストッパ１ａと当接部３ｃとが当接することにより停止して第２付勢手段５の付勢力を当該連動部材２に付与し得る（第１付勢手段４の付勢力は付与されない）ようになっている。これにより、スロットルグリップＧの回転方向に応じて第１付勢手段４又は第２付勢手段５による付勢力を連動部材２に対して適切且つ確実に付与することができる。 As described above, the urging force applying means 3 according to the present embodiment rotates together with the interlocking member 2 when the second urging means 5 is attached and the throttle grip G rotates in the forward direction a, of the second urging means 5. When the throttle grip G rotates in the reverse direction b without applying the urging force to the interlocking member 2 (the urging force of the first urging means 4 is applied), the interlocking member 2 is formed in the case 1 while allowing the rotation. When the stopper 1a and the abutting portion 3c come into contact with each other, the stopper 1a can be stopped and the urging force of the second urging means 5 can be applied to the interlocking member 2 (the urging force of the first urging means 4 is not applied). It has become like. As a result, the urging force by the first urging means 4 or the second urging means 5 can be appropriately and surely applied to the interlocking member 2 according to the rotation direction of the throttle grip G.

ここで、本実施形態においては、スロットルグリップＧが初期位置にあるとき第２付勢手段５の付勢力によりスロットルグリップＧの係合部Ｇａを連動部材２の被係合部２ａに押圧し得る押圧手段１０を具備している。かかる押圧手段１０は、図１２に示すように、第２付勢手段５の付勢力を受ける受け部１０ａ及び壁面１０ｃと、スロットルグリップＧの係合部Ｇａと接触して第２付勢手段５の付勢力を係合部Ｇａに付与する接触部１０ｂとが一体形成された軸状部品から成る。 Here, in the present embodiment, when the throttle grip G is in the initial position, the engaging portion Ga of the throttle grip G can be pressed against the engaged portion 2a of the interlocking member 2 by the urging force of the second urging means 5. The pressing means 10 is provided. As shown in FIG. 12, the pressing means 10 comes into contact with the receiving portion 10a and the wall surface 10c that receive the urging force of the second urging means 5 and the engaging portion Ga of the throttle grip G, and the second urging means 5 It is composed of a shaft-shaped component integrally formed with a contact portion 10b that applies the urging force of the above to the engaging portion Ga.

しかるに、第２付勢手段５は、既述のように、連動部材２における被係合部２ａの間の位置で円弧状に延びて配設されたコイルスプリングから成り、押圧手段１０は、当該コイルスプリングの端部に取り付けられている。受け部１０ａは、図７に示すように、第２付勢手段５の端部（他端）と当接して組み付けられており、当該第２付勢手段５の付勢力が押圧手段１０に付与されるようになっている。 However, as described above, the second urging means 5 is composed of a coil spring that is arranged so as to extend in an arc shape at a position between the engaged portions 2a in the interlocking member 2, and the pressing means 10 is the said. It is attached to the end of the coil spring. As shown in FIG. 7, the receiving portion 10a is assembled in contact with the end portion (the other end) of the second urging means 5, and the urging force of the second urging means 5 is applied to the pressing means 10. It is supposed to be done.

接触部１０ｂは、係止部Ｇａと接触し得る先端が球面を成して構成されるとともに、連動部材２に形成された開口２ｇを挿通した状態にて組み付けられている。かかる開口２ｇは、第２付勢手段５が組み付けられる部位と被係合部２ａとを連通する孔から成り、受け部１０ａ及び壁面１０ｃで受けた第２付勢手段５の付勢力が接触部１０ｂを介して被係合部２ａに係合した係合部Ｇａに付与し得るよう構成されている。なお、押圧手段１０は、係合部Ｇａを壁面２ａｂとは異なる面に押圧するようにしてもよい。 The contact portion 10b is assembled with a tip that can come into contact with the locking portion Ga forming a spherical surface and an opening 2g formed in the interlocking member 2 inserted therein. The opening 2g is composed of a hole for communicating the portion to which the second urging means 5 is assembled and the engaged portion 2a, and the urging force of the second urging means 5 received by the receiving portion 10a and the wall surface 10c is the contact portion. It is configured so that it can be applied to the engaging portion Ga engaged with the engaged portion 2a via the 10b. The pressing means 10 may press the engaging portion Ga against a surface different from the wall surface 2ab.

また、被係合部２ａは、図７に示すように、開口２ｇが形成された壁面２ａａと、該壁面２ａａと対峙した壁面２ａｂとを有する凹形状とされており、押圧手段１０を介して第２付勢手段５の付勢力を受けた係合部Ｇａが壁面２ａｂに押圧されるので、初期位置にあるスロットルグリップＧが連動部材２に対してガタが生じないようになっている。このように、本実施形態に係る押圧手段１０においては、係合部Ｇａを壁面２ａｂに押圧するので、連動部材２の回転方向（正回転ａ側）に向かって押圧することとなり、ガタの防止及び初期位置にあるスロットルグリップＧのガタ防止に加え、被係合部２ａに対する係合部Ｇａの位置決めを図ることができる。 Further, as shown in FIG. 7, the engaged portion 2a has a concave shape having a wall surface 2aa on which an opening 2g is formed and a wall surface 2ab facing the wall surface 2aa, and has a concave shape via the pressing means 10. Since the engaging portion Ga that receives the urging force of the second urging means 5 is pressed against the wall surface 2ab, the throttle grip G at the initial position does not play against the interlocking member 2. As described above, in the pressing means 10 according to the present embodiment, since the engaging portion Ga is pressed against the wall surface 2ab, the interlocking member 2 is pressed in the rotation direction (normal rotation a side) to prevent backlash. In addition to preventing backlash of the throttle grip G at the initial position, the engaging portion Ga can be positioned with respect to the engaged portion 2a.

そして、スロットルグリップＧを初期位置から正回転ａさせると、図１９に示すように、係合部Ｇａが被係合部２ａの壁面２ａｂを押圧して連動部材２を同方向（正回転ａする方向）に回転させるとともに、接触部１０ｂと係合部Ｇａとの接触は維持される。さらに、スロットルＧを初期位置から逆回転ｂさせると、図２０に示すように、係合部Ｇａが第２付勢手段５の付勢力に抗して押圧手段１０を移動させ被係合部２ａの壁面２ａａを押圧し、連動部材２を同方向（逆回転ｂする方向）に回転させる。このとき、接触部１０ａは開口２ｇに没した状態となるものの、接触部１０ａと係合部Ｇａとの接触は維持される。 Then, when the throttle grip G is rotated forward from the initial position, as shown in FIG. 19, the engaging portion Ga presses the wall surface 2ab of the engaged portion 2a to rotate the interlocking member 2 in the same direction (forward rotation a). While rotating in the direction), the contact between the contact portion 10b and the engaging portion Ga is maintained. Further, when the throttle G is rotated in the reverse direction b from the initial position, as shown in FIG. 20, the engaging portion Ga moves the pressing means 10 against the urging force of the second urging means 5, and the engaged portion 2a The wall surface 2aa of the above is pressed, and the interlocking member 2 is rotated in the same direction (direction of reverse rotation b). At this time, although the contact portion 10a is submerged in the opening 2g, the contact between the contact portion 10a and the engaging portion Ga is maintained.

さらに、本実施形態においては、押圧手段１０を有する第２付勢手段５が付勢力付与手段３に取り付けられており、その付勢力付与手段３が連動部材２に組み付けられている。これにより、押圧手段１０のための特別な設置スペースが不要とされ、付勢力付与手段３及び連動部材２の間のスペースを有効活用することができるとともに、ケース１内にデッドスペースが形成されてしまうのを抑制できる。 Further, in the present embodiment, the second urging means 5 having the pressing means 10 is attached to the urging force applying means 3, and the urging force applying means 3 is assembled to the interlocking member 2. As a result, a special installation space for the pressing means 10 is not required, the space between the urging force applying means 3 and the interlocking member 2 can be effectively utilized, and a dead space is formed in the case 1. It can be suppressed from being stored.

しかるに、本実施形態においては、スロットルグリップＧの係合部Ｇａ及び連動部材２の被係合部２ａは、当該スロットルグリップＧの回転方向に亘って等間隔に２つ形成されているが、当該スロットルグリップＧの回転方向に亘って等間隔に複数形成されていれば足り、例えば３つ以上形成し、それら被係合部２ａの間の位置に第２付勢手段５及び押圧手段１０をそれぞれ配設するものとしてもよい。 However, in the present embodiment, two engaging portions Ga of the throttle grip G and two engaged portions 2a of the interlocking member 2 are formed at equal intervals in the rotation direction of the throttle grip G. It suffices if a plurality of throttle grips G are formed at equal intervals in the rotation direction, for example, three or more are formed, and the second urging means 5 and the pressing means 10 are respectively formed at positions between the engaged portions 2a. It may be arranged.

また、スロットルグリップＧが正回転したとき、第２付勢手段５の付勢力を連動部材２に付与させず、スロットルグリップＧが逆回転したとき、第２付勢手段５の付勢力を連動部材２に付与し得る付勢力付与手段３を具備したので、スロットルグリップＧの回転方向に応じて第１付勢手段４及び第２付勢手段５を選択的に作用させることができる。よって、スロットルグリップＧのより円滑な回転操作を行わせることができ、操作性をより向上させることができる。 Further, when the throttle grip G rotates in the forward direction, the urging force of the second urging means 5 is not applied to the interlocking member 2, and when the throttle grip G rotates in the reverse direction, the urging force of the second urging means 5 is applied to the interlocking member. Since the urging force applying means 3 that can be applied to 2 is provided, the first urging means 4 and the second urging means 5 can be selectively acted according to the rotation direction of the throttle grip G. Therefore, the throttle grip G can be rotated more smoothly, and the operability can be further improved.

ここで、本実施形態に係るハンドルスイッチケースＳ（カバー部材）は、図１に示すように、車両の種々電装品を操作する操作スイッチＭが形成され、ハンドルバーＨの先端部に固定されるもので、ケース１が固定される第１カバー部材Ｓａと、第１カバー部材Ｓａと合致してケース１を覆う収容空間が形成される第２カバー部材Ｓｂとを有して構成されている。すなわち、本実施形態に係るハンドルスイッチケースＳは、半割形状の第１カバー部材Ｓａ及び第２カバー部材Ｓ２を有して構成され、これらを合致させて形成される収容空間に連動部材２、磁気センサ７等が配設されたケース１を収容させているのである。 Here, in the handle switch case S (cover member) according to the present embodiment, as shown in FIG. 1, an operation switch M for operating various electrical components of the vehicle is formed and fixed to the tip of the handle bar H. It is configured to include a first cover member Sa to which the case 1 is fixed, and a second cover member Sb that matches the first cover member Sa and forms a storage space for covering the case 1. That is, the handle switch case S according to the present embodiment is configured to have the first cover member Sa and the second cover member S2 having a half-split shape, and the interlocking member 2 is provided in the accommodation space formed by matching these. The case 1 in which the magnetic sensor 7 and the like are arranged is housed.

第１カバー部材Ｓａは、図１３に示すように、一方の側面にスロットルグリップＧの基端部を挿通させる開口Ｓａ１が形成されるとともに、他方の側面にハンドルバーＨを挿通させる開口Ｓａ２が形成されている。また、第１カバー部材Ｓａの一方の側面に形成された開口Ｓａ１は、その縁部に覆い部α及び切欠き部βが形成されるとともに、当該開口Ｓａ１より内側（開口Ｓａ２側）の位置には、突端が車両のハンドルバーＨの外周面に当接してハンドルスイッチケースＳ（カバー部材）を支持可能な支持部Ｓａ３が突出形成されている。 As shown in FIG. 13, the first cover member Sa has an opening Sa1 for inserting the base end portion of the throttle grip G on one side surface and an opening Sa2 for inserting the handlebar H on the other side surface. Has been done. Further, the opening Sa1 formed on one side surface of the first cover member Sa has a covering portion α and a notch portion β formed on the edge thereof, and is located inside the opening Sa1 (on the opening Sa2 side). Is formed with a protruding support portion Sa3 capable of supporting the handle switch case S (cover member) with the tip abutting on the outer peripheral surface of the handlebar H of the vehicle.

第１カバー部材Ｓａの覆い部αは、図１３、１５に示すように、第１カバー部材Ｓａの開口Ｓａ１の縁部に形成され、スロットルグリップＧに形成された鍔部Ｇｂ（図２参照）を覆って抜け止め可能なものである。また、第１カバー部材Ｓａの開口Ｓａ１の縁部には、覆い部αに加え、任意位置に切欠き部βが形成されている。すなわち、第１カバー部材Ｓａの開口Ｓａ１の縁部には、スロットルグリップＧの係合時に当該スロットルグリップＧの基端部と干渉する可能性のある任意の位置に切欠き部βが形成され、他の部位に覆い部αが形成されているのである。 As shown in FIGS. 13 and 15, the cover portion α of the first cover member Sa is formed at the edge of the opening Sa1 of the first cover member Sa, and the flange portion Gb formed in the throttle grip G (see FIG. 2). It is possible to cover and prevent it from coming off. Further, in addition to the covering portion α, a notch portion β is formed at an arbitrary position at the edge portion of the opening Sa1 of the first cover member Sa. That is, a notch β is formed at an arbitrary position on the edge of the opening Sa1 of the first cover member Sa at an arbitrary position where it may interfere with the base end of the throttle grip G when the throttle grip G is engaged. The covering portion α is formed in other parts.

第２カバー部材Ｓｂは、図１４に示すように、一方の側面にスロットルグリップＧの基端部を挿通させる開口Ｓｂ１が形成されるとともに、他方の側面にハンドルバーＨを挿通させる開口Ｓｂ２が形成されている。また、第２カバー部材Ｓｂの一方の側面に形成された開口Ｓｂ１は、その縁部に覆い部γが形成されるとともに、当該開口Ｓｂ１より内側（開口Ｓｂ２側）の位置には、突端が車両のハンドルバーＨの外周面に当接してハンドルスイッチケースＳ（カバー部材）を支持可能な支持部Ｓｂ３が突出形成されている。 As shown in FIG. 14, the second cover member Sb is formed with an opening Sb1 through which the base end portion of the throttle grip G is inserted on one side surface and an opening Sb2 through which the handlebar H is inserted on the other side surface. Has been done. Further, in the opening Sb1 formed on one side surface of the second cover member Sb, a covering portion γ is formed at the edge thereof, and a tip is provided at a position inside the opening Sb1 (on the opening Sb2 side). A support portion Sb3 capable of supporting the handle switch case S (cover member) by contacting the outer peripheral surface of the handle bar H of the above is formed so as to project.

第２カバー部材Ｓｂの覆い部γは、図１３、１４に示すように、第２カバー部材Ｓｂの開口Ｓｂ１の縁部に形成され、第１カバー部材Ｓａに形成された覆い部αと同様、スロットルグリップＧに形成された鍔部Ｇｂ（図２参照）を覆って抜け止め可能なものである。かかる第２カバー部材Ｓｂの開口Ｓｂ１の縁部には、第１カバー部材Ｓｂの開口Ｓａ１の如き切欠き部βは形成されていない。 As shown in FIGS. 13 and 14, the cover portion γ of the second cover member Sb is formed at the edge of the opening Sb1 of the second cover member Sb, and is similar to the cover portion α formed in the first cover member Sa. It covers the flange portion Gb (see FIG. 2) formed on the throttle grip G and can be prevented from coming off. A notch β such as the opening Sa1 of the first cover member Sb is not formed at the edge of the opening Sb1 of the second cover member Sb.

次に、スロットルグリップＧの組み付け方法について説明する。
まず、図１６に示すように、連動部材２や磁気センサ７等が組み付けられたケース１を第１カバー部材Ｓａ内の所定位置にネジ等にて固定した後、スロットルグリップＧを僅かに傾斜させた状態とし、切欠き部βにより干渉を避けつつスロットルグリップＧの基端部を開口Ｓａ１に挿通させる。そして、図１７に示すように、スロットルグリップＧを水平状態にする過程でスロットルグリップＧの係止部Ｇａをケース１内の連動部材２における被係合部２ａに係合させる。 Next, a method of assembling the throttle grip G will be described.
First, as shown in FIG. 16, after fixing the case 1 to which the interlocking member 2 and the magnetic sensor 7 are assembled at a predetermined position in the first cover member Sa with screws or the like, the throttle grip G is slightly tilted. In this state, the base end portion of the throttle grip G is inserted into the opening Sa1 while avoiding interference by the notch portion β. Then, as shown in FIG. 17, in the process of leveling the throttle grip G, the locking portion Ga of the throttle grip G is engaged with the engaged portion 2a of the interlocking member 2 in the case 1.

このように、連動部材２にスロットルグリップＧを係合させた状態においては、支持部Ｓａ３と覆い部αの間に鍔部Ｇｂが介装するとともに、覆い部αが鍔部Ｇｂを覆って抜け止めされることとなる。その後、第２カバー部材Ｓｂを第１カバー部材Ｓａに合致させてネジ等にて固定させることにより、第１カバー部材Ｓａ及び第２カバー部材Ｓｂの覆い部（α、γ）にて鍔部Ｇｂが覆われるとともに、当該覆い部（α、γ）と支持部Ｓａ３及び支持部Ｓｂ３の間に鍔部Ｇｂが位置し、当該鍔部Ｇｂの回転が案内されることとなる。このようにして、ハンドルスイッチケースＳ内にケース１を収容しつつスロットルグリップＧが組み付けられたスロットルグリップ装置を得ることができる。 In this way, in the state where the throttle grip G is engaged with the interlocking member 2, the collar portion Gb is interposed between the support portion Sa3 and the cover portion α, and the cover portion α covers the collar portion Gb and comes off. It will be stopped. After that, by matching the second cover member Sb with the first cover member Sa and fixing it with a screw or the like, the collar portion Gb is formed at the covering portions (α, γ) of the first cover member Sa and the second cover member Sb. Is covered, and the collar portion Gb is located between the cover portion (α, γ) and the support portion Sa3 and the support portion Sb3, so that the rotation of the collar portion Gb is guided. In this way, it is possible to obtain a throttle grip device to which the throttle grip G is assembled while accommodating the case 1 in the handle switch case S.

本実施形態によれば、第１カバー部材Ｓａ及び第２カバー部材Ｓｂは、スロットルグリップＧの基端部を挿通させる開口（Ｓａ１、Ｓｂ１）がそれぞれ形成されるとともに、当該開口（Ｓａ１、Ｓｂ１）の縁部には、スロットルグリップＧに形成された鍔部Ｇｂを覆って抜け止め可能な覆い部（α、γ）が形成されたので、スロットルグリップＧの基端部の形状や大きさ、連動部材２に対する係合位置、開口（Ｓａ１、Ｓｂ１）とケース１との間の離間寸法等に応じて任意の覆い部（α、γ）を形成することができ、スロットルグリップＧの連動部材２に対する係合時の作業性を維持しつつスロットルグリップＧに生じるガタを抑制することができる。 According to the present embodiment, the first cover member Sa and the second cover member Sb are formed with openings (Sa1, Sb1) through which the base end portion of the throttle grip G is inserted, and the openings (Sa1, Sb1) are formed. A covering portion (α, γ) that covers the flange portion Gb formed on the throttle grip G and can be prevented from coming off is formed on the edge portion of the throttle grip G, so that the shape and size of the base end portion of the throttle grip G are interlocked. An arbitrary cover portion (α, γ) can be formed according to the engagement position with respect to the member 2, the separation dimension between the openings (Sa1, Sb1) and the case 1, and the like, with respect to the interlocking member 2 of the throttle grip G. It is possible to suppress backlash generated in the throttle grip G while maintaining workability at the time of engagement.

また、覆い部（α、γ）が形成されることにより、開口（Ｓａ１、Ｓｂ１）の縁部とスロットルグリップＧの基端部との間に大きな隙間ができるのを回避できるので、外部から異物が侵入してしまうのを防止することができるとともに、隙間からハンドルスイッチケースＳの内部が見えてしまうのを回避することができ、意匠性を向上させることができる。さらに、覆い部（α、γ）によってスロットルグリップＧが軸方向に引っ張られた際の強度を向上することができる。 Further, since the covering portion (α, γ) is formed, it is possible to avoid a large gap between the edge portion of the opening (Sa1, Sb1) and the base end portion of the throttle grip G, so that foreign matter can be prevented from the outside. It is possible to prevent the inside of the handle switch case S from being seen through the gap, and it is possible to improve the design. Further, the strength when the throttle grip G is pulled in the axial direction by the covering portion (α, γ) can be improved.

加えて、第１カバー部材Ｓａの開口Ｓａ１の縁部には、覆い部αに加え、任意の所定位置に切欠き部βが形成されたので、スロットルグリップＧの連動部材２に対する係合時、切欠き部βによりスロットルグリップＧの基端部が開口Ｓａ１の縁部に干渉してしまうのを抑制でき、スロットルグリップＧの連動部材２に対する係合時の作業性を向上させることができる。 In addition, at the edge of the opening Sa1 of the first cover member Sa, in addition to the covering portion α, a notch portion β is formed at an arbitrary predetermined position, so that when the throttle grip G is engaged with the interlocking member 2, the throttle grip G is engaged. The notch β can prevent the base end portion of the throttle grip G from interfering with the edge portion of the opening Sa1, and can improve the workability when the throttle grip G is engaged with the interlocking member 2.

また、本実施形態に係る鍔部Ｇｂは、スロットルグリップＧの基端部において周方向全域に亘って形成されたので、開口Ｓａ１の縁部とスロットルグリップＧとの間に多少の隙間（特に、切欠き部βによる隙間）が生じても鍔部Ｇｂにて異物の侵入を防止することができる。なお、鍔部Ｇｂは、周方向全域に亘って形成されたものに限らず、スロットルグリップＧの基端部において周方向の一部に鍔部Ｇｂが形成されないものであってもよい。 Further, since the collar portion Gb according to the present embodiment is formed at the base end portion of the throttle grip G over the entire circumferential direction, there is a slight gap (particularly, particularly) between the edge portion of the opening Sa1 and the throttle grip G. Even if a gap due to the notch portion β) is generated, the intrusion of foreign matter can be prevented by the flange portion Gb. The flange portion Gb is not limited to the one formed over the entire circumferential direction, and the flange portion Gb may not be formed in a part of the circumferential direction at the base end portion of the throttle grip G.

さらに、第１カバー部材Ｓａ及び第２カバー部材Ｓｂは、開口（Ｓａ１、Ｓｂ１）より内側の位置において、車両のハンドルバーＨの外周面に当接してハンドルスイッチケースＳ（カバー部材）を支持可能な支持部（Ｓａ３、Ｓｂ３）が突出形成されるとともに、当該支持部（Ｓａ３、Ｓｂ３）と覆い部（α、γ）の間に鍔部Ｇｂが介装して成るので、スロットルグリップＧの回転時、支持部（Ｓａ３、Ｓｂ３）と覆い部（α、γ）との間で鍔部Ｇｂを案内することができ、スロットルグリップＧを安定して回転させることができる。 Further, the first cover member Sa and the second cover member Sb can abut on the outer peripheral surface of the handlebar H of the vehicle at a position inside the openings (Sa1, Sb1) to support the handle switch case S (cover member). A support portion (Sa3, Sb3) is formed so as to project, and a flange portion Gb is interposed between the support portion (Sa3, Sb3) and a cover portion (α, γ), so that the throttle grip G rotates. At this time, the flange portion Gb can be guided between the support portion (Sa3, Sb3) and the cover portion (α, γ), and the throttle grip G can be stably rotated.

またさらに、カバー部材は、車両の種々電装品を操作する操作スイッチＭが形成されたハンドルスイッチケースＳから成るので、連動部材２及び磁気センサ７（回転角度検出手段）を有したケース１を収容する機能と、ハンドルスイッチとしての機能とを兼ね備えることができる。なお、本実施形態のように、操作スイッチＭが形成されたハンドルスイッチケースＳに限定されず、操作スイッチＭが形成されないカバー部材であってもよい。 Furthermore, since the cover member is composed of a handle switch case S on which an operation switch M for operating various electrical components of the vehicle is formed, the case 1 having the interlocking member 2 and the magnetic sensor 7 (rotation angle detecting means) is accommodated. It can have both the function of performing and the function of a handle switch. As in the present embodiment, the cover member is not limited to the handle switch case S in which the operation switch M is formed, and may be a cover member in which the operation switch M is not formed.

しかるに、本実施形態によれば、スロットルグリップＧが初期位置にあるとき第２付勢手段５の付勢力により係合部Ｇａを被係合部２ａに押圧し得る押圧手段１０を具備したので、スロットルグリップＧの逆回転時に付勢力を生じさせる付勢手段と、ガタを防止するために付勢力を生じさせる付勢手段とを第２付勢手段５が兼ねることができ、付勢手段を増加させることなくスロットルグリップＧと連動部材２との間のガタを抑制することができる。 However, according to the present embodiment, the pressing means 10 capable of pressing the engaging portion Ga against the engaged portion 2a by the urging force of the second urging means 5 when the throttle grip G is in the initial position is provided. The second urging means 5 can serve as both an urging means for generating an urging force when the throttle grip G rotates in the reverse direction and an urging means for generating an urging force to prevent backlash, and the number of urging means is increased. It is possible to suppress backlash between the throttle grip G and the interlocking member 2 without causing the throttle grip G to occur.

以上、本実施形態について説明したが、本発明はこれに限定されるものではなく、例えば本実施形態の如くスロットルグリップＧが正回転及び逆回転可能なものに限らず、専ら一方の方向のみ回転可能なスロットルグリップＧを具備したものであってもよく、第１付勢手段４及び第２付勢手段５とは異なる形態の付勢手段を具備したもの、或いは何れか一方の付勢手段を具備したものであってもよい。 Although the present embodiment has been described above, the present invention is not limited to this, and the throttle grip G is not limited to the one capable of forward rotation and reverse rotation as in the present embodiment, and rotates exclusively in one direction. It may be provided with a possible throttle grip G, and may be provided with an urging means having a form different from that of the first urging means 4 and the second urging means 5, or any one of the urging means. It may be provided.

さらに、本実施形態においては、スロットルグリップＧを逆回転させると、定車速保持装置（オートクルーズ装置）の定車速の保持制御を停止（キャンセル）させるよう構成されているが、スロットルグリップＧの逆方向の回転を検知すると、車両が具備する所定の機能を作動又は非作動するものであれば足りる。例えば、スロットルグリップＧの逆方向の回転により、イモビシステムやスマートエントリシステムにおける認証開始、エンジンを始動させるスタータの作動、ハザード等の緊急時点灯手段の作動等を行わせるものとしてもよい。なお、適用される車両は、本実施形態の如く二輪車に限定されるものではなく、ハンドルバーＨを有した他の車両（例えばＡＴＶやスノーモービル等）に適用してもよい。 Further, in the present embodiment, when the throttle grip G is rotated in the reverse direction, the constant vehicle speed holding control of the constant vehicle speed holding device (auto cruise device) is stopped (cancelled), but the reverse of the throttle grip G. When the rotation in the direction is detected, it suffices as long as it activates or deactivates a predetermined function provided by the vehicle. For example, the rotation of the throttle grip G in the opposite direction may cause the immobilizer system or the smart entry system to start authentication, operate the starter for starting the engine, operate the emergency lighting means such as a hazard, or the like. The vehicle to be applied is not limited to a two-wheeled vehicle as in the present embodiment, and may be applied to other vehicles having a handlebar H (for example, ATV, snowmobile, etc.).

第１カバー部材及び第２カバー部材は、スロットルグリップの基端部を挿通させる開口がそれぞれ形成されるとともに、当該開口の縁部には、スロットルグリップに形成された鍔部を覆って抜け止め可能な覆い部が形成されたスロットルグリップ装置であれば、外観形状が異なるもの或いは他の機能が付加されたもの等にも適用することができる。 The first cover member and the second cover member each have an opening through which the base end portion of the throttle grip is inserted, and the edge portion of the opening can be prevented from coming off by covering the flange portion formed on the throttle grip.
