Description

本発明は、二輪車、船舶やスノーモービル等人員を搭乗させ得る搭乗手段の傾斜を検知し得る搭乗手段の傾斜センサに関するものである。   The present invention relates to an inclination sensor for a riding means capable of detecting the inclination of a riding means capable of carrying a person such as a two-wheeled vehicle, a ship or a snowmobile.

二輪車（搭乗手段）は、走行中に転倒した場合、エンジンを駆動し続けていると二次事故を誘発する可能性がある。このため、当該二輪車が転倒したことを検知してエンジンを停止させるべく、二輪車の傾斜センサが従来より提案されている。この傾斜センサは、例えば特許文献１にて開示されているように、二輪車の傾斜と共に揺動する振り子を傾斜センサ本体内に有するとともに、該振り子の一部に磁界領域を形成しておき、二輪車が転倒して傾くとオフする磁気センサを具備していた。   If the motorcycle (boarding means) falls while traveling, it may induce a secondary accident if the engine is continuously driven. For this reason, in order to detect that the two-wheeled vehicle has fallen and stop the engine, a two-wheeled vehicle tilt sensor has been proposed. As disclosed in, for example, Patent Document 1, this tilt sensor has a pendulum that swings with the tilt of the two-wheeled vehicle in the tilt sensor main body, and a magnetic field region is formed in a part of the pendulum, and the two-wheeled vehicle. It had a magnetic sensor that turned off when it fell and tilted.

すなわち、従来の傾斜センサは、二輪車の直立状態において、振り子の着磁領域と磁気センサとを対向配置しておき、当該磁気センサにて着磁領域を検出させる一方、二輪車が左右方向（車両の幅方向）に傾斜すると、その方向に振り子が揺動して磁気センサから着磁領域が離間し、当該磁気センサがオフすることにより、二輪車の所定角度の傾斜を検知することが可能とされているのである。このため、振り子には、凸状の揺動軸部が形成されており、当該揺動軸部にて傾斜センサ本体に支持されるとともに、二輪車の傾斜に応じて当該振り子が揺動軸部を中心として左右に揺動可能とされている。   That is, in the conventional tilt sensor, in the upright state of the two-wheeled vehicle, the magnetized region of the pendulum and the magnetic sensor are arranged to face each other and the magnetized region is detected by the magnetic sensor. When tilting in the width direction), the pendulum swings in that direction, the magnetized region is separated from the magnetic sensor, and when the magnetic sensor is turned off, it is possible to detect the tilt of the motorcycle at a predetermined angle. It is. For this reason, the pendulum is formed with a convex swing shaft portion, and is supported by the tilt sensor body at the swing shaft portion, and the pendulum has a swing shaft portion according to the inclination of the two-wheeled vehicle. As a center, it can swing left and right.

しかしながら、上記従来の搭乗手段の傾斜センサにおいては、搭乗手段の駆動源（エンジン等）で生じる振動や走行に伴って走行面から受ける振動等により振り子が左右に揺動してしまうことから、当該振動による振り子の揺動が大きい場合、搭乗手段が転倒していないにも関わらず転倒したと誤検知してしまう虞があった。また、磁気センサからの出力信号を処理して、振動で振り子が揺動した際の出力信号を排除することにより、誤検知を抑制することが可能と思われるが、その場合、信号処理のための制御が複雑となってしまうという問題があった。   However, in the above conventional tilt sensor of the riding means, the pendulum swings from side to side due to vibrations generated by the driving source (engine or the like) of the riding means or vibrations received from the running surface during traveling. When the swinging of the pendulum due to the vibration is large, there is a possibility of erroneously detecting that the boarding means has fallen although the boarding means has not fallen. Also, it seems that it is possible to suppress false detection by processing the output signal from the magnetic sensor and eliminating the output signal when the pendulum swings due to vibration. There is a problem that the control of the system becomes complicated.

本発明は、このような事情に鑑みてなされたもので、搭乗手段の振動による誤検知をより確実に防止することができる搭乗手段の傾斜センサを提供することにある。   The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an inclination sensor for riding means that can more reliably prevent erroneous detection due to vibration of the riding means.

本実施形態に係る搭乗手段の傾斜センサＳは、図１０に示すように、人員を搭乗可能な搭乗手段としての二輪車の所定部位に固定されてその転倒方向に対する傾斜（具体的には左右方向の車体の傾斜）を検知するものであり、図１〜３に示すように、傾斜センサ本体１と、振り子２と、磁石３と、検知手段としての磁気センサ４とから主に構成されている。   As shown in FIG. 10, the inclination sensor S of the riding means according to the present embodiment is fixed to a predetermined part of a two-wheeled vehicle as a riding means capable of boarding a person and is inclined with respect to the falling direction (specifically, in the horizontal direction). As shown in FIGS. 1 to 3, the main body is mainly composed of a tilt sensor main body 1, a pendulum 2, a magnet 3, and a magnetic sensor 4 as detection means.

傾斜センサ本体１は、磁気センサ４が形成された基板５が取り付けられる基台部１ａと、該基台部１ａの上部を覆って内部に基板５及び振り子２等を収容させるカバー部１ｂと、カバー部１ｂを二輪車に固定するための固定部Ｃとから主に構成されている。これら基台部１ａ、カバー部１ｂ及び固定部Ｃは、例えば合成樹脂を成形して成るものが好ましい。   The tilt sensor main body 1 includes a base part 1a to which the substrate 5 on which the magnetic sensor 4 is formed is attached, a cover part 1b that covers the upper part of the base part 1a and accommodates the substrate 5, the pendulum 2 and the like inside, It is mainly comprised from the fixing | fixed part C for fixing the cover part 1b to a two-wheeled vehicle. These base part 1a, cover part 1b, and fixing part C are preferably formed by molding synthetic resin, for example.

そして、傾斜センサ本体１は、カバー部１ｂに形成された取付孔１ｂａに対し、基台部１ａに形成された爪部１ａａを嵌入させることにより、基台部１ａとカバー部１ｂとを一体的な部品として構成するようになっている。こうして、傾斜センサ本体１は、固定部Ｃを介して二輪車の所定部位に固定されることにより、当該二輪車と一体的に動作（即ち、二輪車の傾斜と共に傾斜）する。   And the inclination sensor main body 1 integrates the base part 1a and the cover part 1b by fitting the nail | claw part 1aa formed in the base part 1a with respect to the attachment hole 1ba formed in the cover part 1b. It is configured as a simple part. Thus, the tilt sensor main body 1 operates integrally with the two-wheeled vehicle by being fixed to a predetermined part of the two-wheeled vehicle via the fixing portion C (that is, tilted together with the two-wheeled vehicle).

さらに、傾斜センサ本体１は、図４に示すように、基台部１ａの上面から上方に延設された一対の延設部６と、カバー部１ｂの天面から下方に垂下させた一対の垂下部７とがそれぞれ形成されており、基台部１ａにカバー部１ｂを取り付けると、延設部６の突端と垂下部７の突端とが対向するよう構成されている。また、延設部６の突端には、取付面６ａが形成されるとともに、垂下部７の突端には、矩形状の切欠き７ａが形成されており、基台部１ａにカバー部１ｂを取り付けると、これら取付面６ａと切欠き７ａとで後述する振り子２の揺動軸部２ａを支持する支持部が形成されるようになっている。   Further, as shown in FIG. 4, the tilt sensor main body 1 includes a pair of extending portions 6 extending upward from the upper surface of the base portion 1a and a pair of hanging portions hanging downward from the top surface of the cover portion 1b. A hanging portion 7 is formed. When the cover portion 1b is attached to the base portion 1a, the protruding end of the extending portion 6 and the protruding end of the hanging portion 7 are configured to face each other. A mounting surface 6a is formed at the protruding end of the extended portion 6, and a rectangular notch 7a is formed at the protruding end of the hanging portion 7, and the cover portion 1b is attached to the base portion 1a. The mounting surface 6a and the notch 7a form a support portion that supports a swing shaft portion 2a of the pendulum 2 described later.

このようにして、揺動軸部２ａは、取付面６ａ及び切欠き７ａで構成される支持部にて支持されつつ回転動作自在とされており、当該揺動軸部２ａを中心とした振り子２の揺動を許容可能としている。なお、振り子２の揺動軸部２ａを支持する支持部は、上記の如く取付面６ａ及び切欠き７ａで構成されるものに限らず、例えば延設部６又は垂下部７に貫通孔を形成しておき、当該貫通孔にて揺動軸部２ａを支持させるようにしてもよい。   In this way, the swinging shaft portion 2a is freely rotatable while being supported by the support portion constituted by the mounting surface 6a and the notch 7a, and the pendulum 2 centering on the swinging shaft portion 2a. Is allowed to swing. In addition, the support part which supports the rocking | fluctuation shaft part 2a of the pendulum 2 is not restricted to what is comprised by the attachment surface 6a and the notch 7a as mentioned above, For example, a through-hole is formed in the extension part 6 or the hanging part 7 In addition, the swing shaft portion 2a may be supported by the through hole.

振り子２は、図５、６に示すように、傾斜センサ本体１に形成された支持部（取付面６ａ及び切欠き７ａ）に支持される凸状の揺動軸部２ａを有するとともに、二輪車の傾斜（本実施形態においては左右方向の傾斜）に応じて当該揺動軸部２ａを中心として揺動し得るものである。本実施形態に係る振り子２は、例えば亜鉛ダイカストから成るもので、揺動軸部２ａが一体成形されている。なお、振り子２は、揺動軸部を別体部品とし、その揺動軸部を振り子に組み付けるようにしてもよい。   As shown in FIGS. 5 and 6, the pendulum 2 has a convex swing shaft portion 2 a supported by a support portion (mounting surface 6 a and notch 7 a) formed in the tilt sensor main body 1, and a two-wheeled vehicle. According to the inclination (in the present embodiment, the inclination in the left-right direction), it can swing around the swinging shaft portion 2a. The pendulum 2 according to the present embodiment is made of, for example, zinc die casting, and the swing shaft portion 2a is integrally formed. The pendulum 2 may be configured such that the swing shaft portion is a separate part and the swing shaft portion is assembled to the pendulum.

また、振り子２には、図５に示すように、磁石３が固定されており、二輪車が傾斜するのに伴って当該振り子２と共に磁石３が揺動軸部２ａを中心として揺動可能とされている。例えば、振り子２及び磁石３には、それぞれの表裏を貫通する貫通孔が形成されており、磁石３を振り子２の所定部位に嵌め合わせた状態で当該貫通孔にスプリングピンｐを挿通させることにより、振り子２と磁石３とが固定されるよう構成されている。   Further, as shown in FIG. 5, a magnet 3 is fixed to the pendulum 2, and the magnet 3 can swing around the swinging shaft portion 2a together with the pendulum 2 as the two-wheeled vehicle tilts. ing. For example, the pendulum 2 and the magnet 3 are formed with through holes penetrating the front and back, and the spring pin p is inserted into the through hole in a state where the magnet 3 is fitted to a predetermined part of the pendulum 2. The pendulum 2 and the magnet 3 are configured to be fixed.

磁石３は、振り子２と共に揺動し得るもので、ボンド磁石（所謂プラスチック磁石）から成るものである。ここで、ボンド磁石とは、微小な磁石粉を樹脂等のバインダ（結合剤）と混ぜ合わせて成型固化して製造される磁石をいい、一般的に用られる磁石粉として、フェライト系磁石や希土類系磁石等が挙げられる。   The magnet 3 can swing with the pendulum 2 and is composed of a bond magnet (so-called plastic magnet). Here, the bond magnet refers to a magnet produced by mixing and molding a minute magnet powder with a binder (binder) such as a resin, and as a commonly used magnet powder, a ferrite magnet or a rare earth System magnets and the like.

以上の構成により、振り子２は、二輪車の非傾斜時、図２、３に示すように、磁石３が磁気センサ４と対向する中立位置で静止しており、当該二輪車が左右方向に傾斜して揺動軸部２ａを中心に揺動すると、磁石３と磁気センサ４との相対的位置が逐次変化し、二輪車が所定以上傾斜すると、当該磁石３が磁気センサ４から遠ざかるよう傾斜センサ本体１内に組み付けられている。   With the above configuration, when the two-wheeled vehicle is not tilted, the pendulum 2 is stationary at the neutral position where the magnet 3 faces the magnetic sensor 4 as shown in FIGS. When swinging about the swinging shaft portion 2a, the relative position of the magnet 3 and the magnetic sensor 4 sequentially changes, and when the two-wheeled vehicle is tilted by a predetermined amount or more, the magnet 3 moves away from the magnetic sensor 4 in the tilt sensor main body 1. It is assembled to.

磁気センサ４（検知手段）は、基台部１ａに固定された基板５に形成されるとともに、磁石３からの磁気に基づき振り子２の揺動を検知して二輪車（搭乗手段）が所定角度傾いたか否かを検知するためのものである。具体的には、磁気センサ４は、振り子２の磁石３が生成する磁界領域が傾斜センサ本体１に対して所定位置（車両の非傾斜時において静止する中立位置）にあるか否かを検知するもので、磁石３が当該中立位置にないことが検知（即ち、磁界を検知しない）された場合、車両側に信号（電圧変化に基づく信号）を送信するよう構成されている。   The magnetic sensor 4 (detecting means) is formed on the substrate 5 fixed to the base portion 1a, and detects the swing of the pendulum 2 based on the magnetism from the magnet 3 so that the two-wheeled vehicle (boarding means) is inclined at a predetermined angle. It is for detecting whether or not. Specifically, the magnetic sensor 4 detects whether or not the magnetic field region generated by the magnet 3 of the pendulum 2 is at a predetermined position (neutral position when the vehicle is not tilted) with respect to the tilt sensor body 1. Therefore, when it is detected that the magnet 3 is not in the neutral position (that is, the magnetic field is not detected), a signal (a signal based on a voltage change) is transmitted to the vehicle side.

こうして、傾斜センサＳは、磁気センサ４により、振り子２の揺動を非接触で検知して二輪車の傾斜を検知し得るようになっている。なお、磁気センサ４は、磁界領域の磁気を非接触にて検知し得るものであれば種々汎用品を用いることができ、例えばホールＩＣ素子を有するホールセンサや磁気抵抗センサ等を使用することができる。   Thus, the tilt sensor S can detect the tilt of the two-wheeled vehicle by detecting the swing of the pendulum 2 in a non-contact manner by the magnetic sensor 4. As the magnetic sensor 4, various general-purpose products can be used as long as they can detect the magnetism in the magnetic field region without contact. For example, a Hall sensor having a Hall IC element or a magnetoresistive sensor can be used. it can.

一方、基板５には、図９に示すように、磁気センサ４が形成されるとともに所定の電気回路（配線パターン）が実装されており、電源端子ｔ１、出力端子ｔ２及びグランド端子ｔ３が形成されている。すなわち、磁気センサ４は、電源端子ｔ１及びグランド端子ｔ３により電力供給が成されるとともに、出力端子ｔ２により、磁界の検知又は非検知に関わる電気信号を車両側に出力するよう構成されているのである。なお、同図中符号Ｃはコンデンサ、及びＲ１、Ｒ２は抵抗を示している。   On the other hand, as shown in FIG. 9, a magnetic sensor 4 is formed on the substrate 5, and a predetermined electric circuit (wiring pattern) is mounted thereon, and a power supply terminal t1, an output terminal t2, and a ground terminal t3 are formed. ing. That is, the magnetic sensor 4 is configured so that power is supplied by the power supply terminal t1 and the ground terminal t3, and an electric signal related to detection or non-detection of the magnetic field is output to the vehicle side by the output terminal t2. is there. In the figure, symbol C indicates a capacitor, and R1 and R2 indicate resistors.

ここで、本実施形態に係る振り子２の揺動軸部２ａは、図５、６に示すように、その周面に角部２ａａを有して成り、振り子２が中立位置から所定角度α揺動したとき、当該角部２ａａが傾斜センサ本体１に形成された支持部（６ａ、７ａ）に当接し得る（図７参照）よう構成されている。具体的には、揺動軸部２ａは、円筒状部材の側面に一対の平面Ｈ（２つの略平行な平面）が形成された形状から成り、当該平面Ｈの縁部（本実施形態においては円弧部Ｋとの境界部）が角部２ａａを成すようになっている。これにより、二輪車の振動により振り子２が中立位置から左方向又は右方向に所定角度α傾斜すると、角部２ａａが支持部（６ａ、７ａ）に当接することとなる。   Here, as shown in FIGS. 5 and 6, the swing shaft portion 2a of the pendulum 2 according to the present embodiment has a corner portion 2aa on the peripheral surface, and the pendulum 2 swings by a predetermined angle α from the neutral position. When moved, the corner 2aa is configured to come into contact with the support portions (6a, 7a) formed on the tilt sensor body 1 (see FIG. 7). Specifically, the swing shaft portion 2a has a shape in which a pair of planes H (two substantially parallel planes) are formed on the side surface of the cylindrical member, and an edge portion of the plane H (in the present embodiment). The boundary portion with the arc portion K) forms a corner portion 2aa. As a result, when the pendulum 2 is tilted from the neutral position to the left or right by a predetermined angle α due to vibration of the two-wheeled vehicle, the corner 2aa comes into contact with the support portions (6a, 7a).

また、揺動軸部２ａは、その周面に角部２ａａと連なって形成された円弧部Ｋを有して成り、振り子２が所定角度αより大きく揺動したとき、図８に示すように、当該円弧部Ｋが傾斜センサ本体１に形成された支持部７ａに当接し得るよう構成されている。すなわち、振り子２は、所定角度αまで揺動すると、図７に示すように、角部２ａａが支持部７ａの壁面に当接して揺動方向と逆方向に反力を受け、更なる揺動が規制されるとともに、所定角度αを超えて揺動すると、図８に示すように、円弧部Ｋが支持部７ａの壁面に当接して円滑な揺動動作が図られるのである。   Further, the swing shaft portion 2a has an arc portion K formed on the peripheral surface thereof so as to be continuous with the corner portion 2aa, and when the pendulum 2 swings larger than a predetermined angle α, as shown in FIG. The arc portion K is configured to come into contact with a support portion 7a formed in the tilt sensor body 1. That is, when the pendulum 2 swings to a predetermined angle α, as shown in FIG. 7, the corner portion 2aa comes into contact with the wall surface of the support portion 7a and receives a reaction force in the direction opposite to the swinging direction. When the angle is restricted and swings beyond a predetermined angle α, the arc K is brought into contact with the wall surface of the support portion 7a as shown in FIG.

ここで、本実施形態に係る角部２ａａは、二輪車の振動特性に応じた位置に形成されている。すなわち、振り子２は、一対の平面Ｈを形成する位置を変更することにより、揺動軸部２ａの周面における角部２ａａの形成位置を任意に設定することができることから、二輪車の振動が比較的大きいと想定される場合、所定角度αを大きく設定し、二輪車の振動が比較的小さいと想定される場合、所定角度αを小さく設定することにより、二輪車の振動特性に応じて振り子２の揺動規制角度（すなわち、角部２ａａと支持部（６ａ、７ａ）とが当接する角度）を種々変更させることができるのである。   Here, the corner | angular part 2aa which concerns on this embodiment is formed in the position according to the vibration characteristic of the two-wheeled vehicle. That is, the pendulum 2 can arbitrarily set the formation position of the corner portion 2aa on the peripheral surface of the swing shaft portion 2a by changing the position where the pair of planes H are formed. If it is assumed that the predetermined angle α is large, and if the vibration of the two-wheeled vehicle is assumed to be relatively small, the predetermined angle α is set small so that the swing of the pendulum 2 depends on the vibration characteristics of the two-wheeled vehicle. The movement restriction angle (that is, the angle at which the corner portion 2aa and the support portion (6a, 7a) abut) can be variously changed.

上記の如く本実施形態の傾斜センサＳは、二輪車のエンジンから生じる振動や走行時に走行面（路面）から付与される振動により振り子２が中立位置から所定角度α揺動すると、角部２ａａが支持部７ａに当接して当該支持部７ａから反力を受け、更なる揺動が規制されるので、当該振動による誤検知をより確実に防止できる。また、揺動軸部２ａは、その周面に角部２ａａと連なって形成された円弧部Ｋを有して成り、振り子２が所定角度αより大きく揺動したとき、当該円弧部Ｋが支持部７ａに当接し得るので、二輪車の振動による誤検知をより確実に防止することができるとともに、二輪車の傾斜をより円滑かつ精度よく検知することができる。   As described above, the inclination sensor S of the present embodiment is supported by the corner portion 2aa when the pendulum 2 swings by a predetermined angle α from the neutral position due to vibration generated from the engine of the two-wheeled vehicle or vibration applied from the traveling surface (road surface) during traveling. Since it abuts against the portion 7a and receives a reaction force from the support portion 7a and further swinging is restricted, erroneous detection due to the vibration can be prevented more reliably. Further, the swing shaft portion 2a has an arc portion K formed on the peripheral surface thereof so as to be continuous with the corner portion 2aa, and when the pendulum 2 swings more than a predetermined angle α, the arc portion K is supported. Since it can contact the part 7a, it is possible to more reliably prevent erroneous detection due to vibration of the two-wheeled vehicle and to detect the inclination of the two-wheeled vehicle more smoothly and accurately.

特に、本実施形態に係る振り子２の揺動軸部２ａは、当該振り子２から突出した円筒状部材の側面に一対の平面Ｈが形成された形状から成り、当該平面Ｈの縁部が角部２ａａを成すので、より簡易に角部２ａａを有した揺動軸部２ａを形成することができる。さらに、本実施形態によれば、角部２ａａは、二輪車（搭乗手段）の振動特性に応じた位置に形成されたので、二輪車（搭乗手段）の振動による誤検知をより一層防止することができ、より精度よく二輪車の傾斜を検知することができる。   In particular, the swing shaft portion 2a of the pendulum 2 according to the present embodiment has a shape in which a pair of planes H are formed on the side surfaces of a cylindrical member protruding from the pendulum 2, and the edges of the plane H are corner portions. Since 2aa is comprised, the rocking | fluctuation shaft part 2a which has the corner | angular part 2aa can be formed more simply. Furthermore, according to the present embodiment, the corner 2aa is formed at a position corresponding to the vibration characteristics of the two-wheeled vehicle (boarding means), so that erroneous detection due to vibration of the two-wheeled vehicle (boarding means) can be further prevented. Thus, the inclination of the motorcycle can be detected with higher accuracy.

以上、本実施形態に係る搭乗手段の傾斜センサについて説明したが、本発明はこれに限定されず、例えば図１１に示すように、揺動軸部２ａの周面に形成された平面Ｈと円弧部Ｋとの間に平面Ｈ’（平面Ｈとは別個の平面）を介在させたものとし、角部２ａａを上記実施形態のものより増加させたものとしてもよい。また、揺動軸部２ａに形成される一対の平面Ｈは、上記実施形態の如く略平行のものに限定されず、図１２に示すように、平行でない一対の平面としてもよい。   The tilt sensor of the boarding means according to the present embodiment has been described above. However, the present invention is not limited to this, and for example, as shown in FIG. 11, a plane H and an arc formed on the peripheral surface of the swing shaft portion 2a. A plane H ′ (a plane different from the plane H) may be interposed between the portion K and the corner 2aa may be increased from that of the above embodiment. Further, the pair of planes H formed on the swing shaft portion 2a is not limited to a substantially parallel plane as in the above embodiment, and may be a pair of planes that are not parallel as shown in FIG.

さらに、本実施形態の傾斜センサにおいては、二輪車（搭乗手段）の転倒を検知するものとされているが、二輪車（搭乗手段）の傾斜角度を逐次検知するものや、あるいは、検知された傾斜角度を単に表示するものに適用してもよい。またさらに、本実施形態の傾斜センサは、二輪車（搭乗手段）の転倒を検知するとエンジンを停止させるよう構成されているが、これに代えて転倒を検知した場合であってもエンジンの停止を伴わないもの（例えば単にアイドリングさせるもの等）であってもよい。なお、本実施形態の傾斜センサは、二輪車に適用されているが、例えば二輪車の他、バギーやスノーモービル、或いは船外機付きの船舶やウォータビークル等人員を搭載させ得る種々の搭乗手段に固定して、これらの傾斜を検知するものとしてもよい。   Furthermore, in the inclination sensor of this embodiment, it is assumed that the fall of the two-wheeled vehicle (boarding means) is detected, but the one that sequentially detects the inclination angle of the two-wheeled vehicle (boarding means), or the detected inclination angle. May be applied to a simple display. Furthermore, the tilt sensor according to the present embodiment is configured to stop the engine when a fall of the two-wheeled vehicle (boarding means) is detected. However, instead of this, even when a fall is detected, the engine is stopped. It may be something that is not (for example, something that is simply idled). The tilt sensor of the present embodiment is applied to a two-wheeled vehicle, but is fixed to various boarding means that can carry a person such as a buggy, a snowmobile, a ship with an outboard motor or a water vehicle, for example. And it is good also as what detects these inclinations.

揺動軸部は、その周面に角部を有して成り、振り子が中立位置から所定角度揺動したとき、当該角部が支持部に当接し得る搭乗手段の傾斜センサであれば、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 swing shaft portion has a corner portion on its peripheral surface, and when the pendulum swings a predetermined angle from the neutral position, if the corner portion is a tilt sensor of the riding means that can contact the support portion, the appearance The present invention can also be applied to ones with different shapes or other functions added.
