It includes magnets Ma and Mb, a pipe-shaped member 10, and a frame part F. Further, the self-holding solenoid S according to the present embodiment has a plunger P that can be displaced by the magnetic force generated by energizing the coil C and the magnetic force of the permanent magnets Ma and Mb, and the plunger P is connected to the lock bar R.

　フレーム部Ｆは、自己保持型ソレノイドＳの筐体を構成するもので、図６、７に示すように、コ字状に折り曲げ加工された金属部品から成り、コイルＣ、プランジャＰ、永久磁石Ｍａ、Ｍｂ及びパイプ状部材１０が取り付けられるとともに、カバー部材３の所定位置に固定されている。なお、フレーム部Ｆの端部には、図５及び図７、８に示すように、板状の蓋部材Ｆａがかしめ等により固定されている。 The frame part F constitutes the housing of the self-holding solenoid S, and as shown in FIGS. , Mb and the pipe-shaped member 10 are attached and fixed at a predetermined position on the cover member 3. In addition, as shown in FIG. 5 and FIGS. 7 and 8, a plate-shaped lid member Fa is fixed to the end of the frame portion F by caulking or the like.
　コイルＣは、配線ｈ１、ｈ２（図６参照）を介して通電可能とされ、通電により磁気を生じさせて、その磁力によりプランジャＰを変位させ得るよう構成されている。プランジャＰは、パイプ状部材１０内に収容されるとともに、基端部側がコイルＣ内に位置して組付けられている。なお、フレーム部Ｆには、受け部材１１（図３、５参照）が取り付けられており、当該受け部材１１にパイプ状部材１０の基端が固定されるとともに、プランジャＰの基端部Ｐ２を受け得るようになっている。 The coil C can be energized via the wirings h1 and h2 (see FIG. 6), and is configured to generate magnetism when energized and displace the plunger P by the magnetic force. The plunger P is housed within the pipe-like member 10 and is assembled with its base end located within the coil C. A receiving member 11 (see FIGS. 3 and 5) is attached to the frame portion F, and the base end of the pipe-like member 10 is fixed to the receiving member 11, and the base end P2 of the plunger P is fixed to the receiving member 11. It is now possible to receive it.
　かかるパイプ状部材１０は、例えば真鍮など高い電気伝導性を有した円筒状の金属部品から成り、内部にプランジャＰを変位可能に収容するとともに永久磁石Ｍａ、Ｍｂが取り付けられている。永久磁石Ｍａ、Ｍｂは、互いに同極（Ｓ極どうし又はＮ極どうし）のものを２つ組み合わせ、パイプ状部材１０の外周面とフレーム部Ｆの内周面との間に固定されたものである。 The pipe-like member 10 is made of a cylindrical metal part having high electrical conductivity, such as brass, and accommodates the plunger P movably therein, and has permanent magnets Ma and Mb attached thereto. The permanent magnets Ma and Mb are a combination of two of the same polarity (S poles or N poles) and are fixed between the outer circumferential surface of the pipe-shaped member 10 and the inner circumferential surface of the frame portion F. be.
　本実施形態に係る連結部材６は、図３、５、７、８に示すように、自己保持型ソレノイドＳのプランジャＰとロックバーＲとを略直交する方向に連結し、プランジャＰの変位方向に対して略直交する方向にロックバーＲを移動させるもので、図１３に示すように、第１連結溝６ａと、第２連結溝６ｂと、挿通孔６ｃとを有して構成されている。 As shown in FIGS. 3, 5, 7, and 8, the connecting member 6 according to the present embodiment connects the plunger P of the self-retaining solenoid S and the lock bar R in a direction substantially orthogonal to each other, and As shown in FIG. 13, it is configured to have a first connecting groove 6a, a second connecting groove 6b, and an insertion hole 6c. .
　第１連結溝６ａは、プランジャＰの先端部に形成された突出部Ｌ１を挿通してプランジャＰと連結し得るとともに、第２連結溝６ｂは、ロックバーＲに形成された突出部Ｌ２を挿通してロックバーＲと連結し得るようになっている。また、挿通孔６ｃは、カバー部材３に形成された突出部Ｌ３を挿通し、連結部材６をカバー部材３に対して揺動自在とされている。なお、プランジャＰの先端部には、挿通孔Ｐ１が形成されており、当該挿通孔Ｐ１に突出部Ｌ１が挿通されるとともに、プランジャＰの基端部Ｐ２を受け部材１１が受け得るようになっている。 The first connecting groove 6a can pass through a protrusion L1 formed at the tip of the plunger P and connect to the plunger P, and the second connection groove 6b can pass through a protrusion L2 formed on the lock bar R. It is designed so that it can be connected to the lock bar R. Further, a protrusion L3 formed on the cover member 3 is inserted into the insertion hole 6c, so that the connecting member 6 can freely swing relative to the cover member 3. Note that an insertion hole P1 is formed at the tip of the plunger P, and the protrusion L1 is inserted into the insertion hole P1, and the receiving member 11 can receive the proximal end P2 of the plunger P. ing.
　さらに、本実施形態に係る連結部材６は、図１３に示すように、所定部位に接点７が取り付けられている。これにより、連結部材６が突出部Ｌ３を中心として揺動するのに伴って接点７も移動し得るようになっている。かかる接点７と対向する位置には、図１１、１２に示すように、第１接触板９ａ、第２接触板９ｂ及び第３接触板９ｃを有した固定端子板８が取り付けられている。 Furthermore, as shown in FIG. 13, the connecting member 6 according to this embodiment has contacts 7 attached to predetermined locations. Thereby, as the connecting member 6 swings about the protrusion L3, the contact 7 can also move. A fixed terminal plate 8 having a first contact plate 9a, a second contact plate 9b, and a third contact plate 9c is attached at a position facing the contact 7, as shown in FIGS. 11 and 12.
　固定端子板８は、その一方の面において接点７を摺動させ得るもので、第１接触板９ａ、第２接触板９ｂ及び第３接触板９ｃからそれぞれ配線ｈ３～ｈ５が延設されており、これら配線ｈ３～ｈ５は、検出手段１３と接続されている。かかる検出手段１３は、車体側に設置されたマイコン等から成り、ロックバーＲが突出状態とされて接点７が位置Ｈ１（図１２参照）にあるとき、第１接触板９ａと第３接触板９ｃとの間を導通して電気回路が形成されるとともに、ロックバーＲが没入状態とされて接点７が位置Ｈ２（図１２参照）にあるとき、第２接触板９ｂと第３接触板９ｃとの間を導通して電気回路が形成されるようになっている。 The fixed terminal plate 8 allows the contact 7 to slide on one surface thereof, and has wiring h3 to h5 extending from the first contact plate 9a, the second contact plate 9b, and the third contact plate 9c, respectively. , these wirings h3 to h5 are connected to the detection means 13. The detection means 13 is composed of a microcomputer or the like installed on the vehicle body side, and when the lock bar R is in the protruding state and the contact point 7 is at the position H1 (see FIG. 12), the first contact plate 9a and the third contact plate 9c to form an electric circuit, and when the lock bar R is retracted and the contact point 7 is at position H2 (see FIG. 12), the second contact plate 9b and the third contact plate 9c An electric circuit is formed by conducting between the two.
　したがって、検出手段１３は、第１接触板９ａ、第２接触板９ｂ及び第３接触板９ｃとそれぞれ接続されているので、接点７と第１接触板９ａ、第２接触板９ｂ及び第３接触板９ｃとの間に形成された電気回路に基づいてロックバーＲの位置を検出することができ、例えば非接触センサ等の別個のセンサを具備することなく、ロックバーＲの突出状態又は没入状態を検出することができる。 Therefore, since the detection means 13 is connected to the first contact plate 9a, the second contact plate 9b, and the third contact plate 9c, respectively, the contact point 7 and the first contact plate 9a, the second contact plate 9b, and the third contact plate are connected to each other. The position of the lock bar R can be detected based on the electric circuit formed between the plate 9c, and the position of the lock bar R can be detected in the protruding or retracted state without the need for a separate sensor such as a non-contact sensor. can be detected.
　一方、本実施形態においては、図６に示すように、配線ｈ１、ｈ２を介して自己保持型ソレノイドＳと制御手段１２とが接続可能とされている。かかる制御手段１２は、車体側に設置されたマイコン等から成り、配線ｈ１、ｈ２を介して自己保持型ソレノイドＳと電気的に接続され、任意のタイミングで自己保持型ソレノイドＳのコイルＣに通電可能とされている。 On the other hand, in this embodiment, as shown in FIG. 6, the self-holding solenoid S and the control means 12 can be connected via wiring h1 and h2. The control means 12 consists of a microcomputer installed on the vehicle body side, is electrically connected to the self-holding solenoid S via wiring h1 and h2, and energizes the coil C of the self-holding solenoid S at any timing. It is considered possible.
　そして、コイルＣに通電されない状態において、永久磁石Ｍａ、Ｍｂの磁力によるプランジャＰの吸引力は、付勢部材５の付勢力より大きく設定されており、図５に示すように、プランジャＰを吸引した状態が維持され、ロックバーＲの没入状態が保持されるようになっている。この没入状態からコイルＣに対して所定方向に電流を流して通電（順方向の通電）すると、コイルＣに生じた磁力と永久磁石Ｍａ、Ｍｂによる磁力とが互いに打ち消し合うこととなり、図３に示すように、付勢部材５の付勢力によってプランジャＰがパイプ状部材１０内を摺動してロックバーＲが突出状態とされる。 When the coil C is not energized, the attraction force of the plunger P due to the magnetic force of the permanent magnets Ma and Mb is set to be larger than the urging force of the urging member 5, and as shown in FIG. This state is maintained, and the retracted state of the lock bar R is maintained. When a current is applied to the coil C in a predetermined direction from this immersed state (forward energization), the magnetic force generated in the coil C and the magnetic force caused by the permanent magnets Ma and Mb cancel each other out, as shown in FIG. As shown, the plunger P slides within the pipe-like member 10 due to the biasing force of the biasing member 5, and the lock bar R is brought into a protruding state.
　さらに、この突出状態からコイルＣに対して所定方向とは逆方向に電流を流して通電（逆方向の通電）すると、コイルＣで生じる磁力と永久磁石Ｍａ、Ｍｂの磁力とが同一方向に作用することとなり、図５に示すように、コイルＣで生じる磁力及び永久磁石Ｍａ、Ｍｂの磁力によってプランジャＰがパイプ状部材１０内を摺動してロックバーＲが没入状態とされる。かかる没入状態において通電を終了させると、永久磁石Ｍａ、Ｍｂの磁力によってロックバーＲの没入状態が保持されることとなる。 Furthermore, when a current is applied to the coil C in the opposite direction to the predetermined direction from this protruding state (reverse direction energization), the magnetic force generated in the coil C and the magnetic force of the permanent magnets Ma and Mb act in the same direction. As shown in FIG. 5, the plunger P slides within the pipe-shaped member 10 due to the magnetic force generated by the coil C and the magnetic force of the permanent magnets Ma and Mb, and the lock bar R is brought into the retracted state. When energization is terminated in such a retracted state, the retracted state of the lock bar R is maintained by the magnetic force of the permanent magnets Ma and Mb.
　したがって、自己保持型ソレノイドＳによれば、コイルＣに通電されない状態において、永久磁石Ｍａ、Ｍｂの磁力によってロックバーＲの没入状態が保持されるとともに、コイルＣに対する所定方向の電流の付与（順方向の通電）によりロックバーＲを突出状態まで移動させ、且つ、コイルＣに対する所定方向とは反対方向の電流の付与（逆方向の通電）によりロックバーＲを没入状態まで移動させることができる。 Therefore, according to the self-holding solenoid S, when the coil C is not energized, the retracted state of the lock bar R is maintained by the magnetic force of the permanent magnets Ma and Mb, and current is applied to the coil C in a predetermined direction (sequentially). The lock bar R can be moved to the protruding state by applying current to the coil C in the opposite direction to the predetermined direction (current being applied in the opposite direction), and the lock bar R can be moved to the retracted state by applying current to the coil C in the opposite direction to the predetermined direction (current being applied in the opposite direction).
　しかるに、例えば、ロックバーＲの係止が不良であり不用意な負荷が付与されていて没入状態にならない場合、コイルＣに逆方向の通電をしてロックバーＲを突出状態から没入状態に移動させようとしても、突出状態が維持されることとなる。そこで、本実施形態においては、コイルＣに通電（逆方向の通電）してプランジャＰを吸引し、且つ、検出手段１３にてロックバーＲが突出状態の位置にあることが検出されたとき、制御手段１２によってコイルＣに所定回数繰り返し通電するよう制御されるようになっている。 However, if, for example, the lock bar R is not properly locked and the retracted state is not achieved due to an inadvertent load being applied, the coil C is energized in the opposite direction to move the lock bar R from the protruding state to the retracted state. Even if an attempt is made to do so, the protruding state will be maintained. Therefore, in this embodiment, when the coil C is energized (energized in the opposite direction) to attract the plunger P, and the detection means 13 detects that the lock bar R is in the protruding position, The control means 12 controls the coil C to be repeatedly energized a predetermined number of times.
　このように、本実施形態においては、検出手段１３にてロックバーＲの位置を検出することにより、係止不良等によりロックバーＲが突出状態から没入状態にならないことを把握することができるので、制御手段１２によってコイルＣに所定回数繰り返し通電（例えば１秒に１回、複数回数繰り返し通電）することにより、係止不良の解消を促すことができ、ロックバーＲを没入状態とすることができる。 In this way, in this embodiment, by detecting the position of the lock bar R with the detection means 13, it is possible to know that the lock bar R does not change from the protruding state to the retracted state due to a locking failure or the like. By repeatedly energizing the coil C a predetermined number of times by the control means 12 (for example, repeatedly energizing a plurality of times once per second), it is possible to promote the resolution of the locking failure and to bring the lock bar R into the retracted state. can.
　ここで、本実施形態に係るステアリングロック装置１は、図１４～１７に示すように、車両のフロントフォークＤを連結するブラケットＢに取り付けられるとともに、ロックバーＲは、車両のステアリングの回動軸Ｎと略平行な方向（図１７における上下方向）に移動可能に取り付けられている。なお、車両のハンドルバーＪ、ハンドルバーＪの操作に伴って回転する回動軸Ｎ、および回動軸Ｎを収容する外筒部Ｔにより車両のステアリングＷが構成されている。 Here, as shown in FIGS. 14 to 17, the steering lock device 1 according to the present embodiment is attached to a bracket B that connects a front fork D of a vehicle, and a lock bar R is attached to a rotation axis of a steering wheel of a vehicle. It is attached so as to be movable in a direction substantially parallel to N (vertical direction in FIG. 17). Note that the steering wheel W of the vehicle is constituted by the handlebar J of the vehicle, a rotation shaft N that rotates as the handlebar J is operated, and an outer cylindrical portion T that accommodates the rotation shaft N.
　本実施形態においては、例えば小型のスクータから成る自動二輪車に適用されており、フロントフォークＤを連結するブラケットＢ（アッパブラケット）の所定位置（例えばブラケットＢにおける回動軸Ｎより車両前方側の位置）にステアリングロック装置１が取り付けられている。また、ブラケットＢには、図１６、１７に示すように、ステアリングロック装置１のケース部材２の形状（外観形状）に倣った凹部Ｂａが形成されており、かかる凹部Ｂａにケース部材２が嵌入されている。 In this embodiment, it is applied to a motorcycle consisting of a small scooter, for example, and a predetermined position of a bracket B (upper bracket) that connects a front fork D (for example, a position on the front side of the vehicle from the rotation axis N of the bracket B) is applied. ) is attached with a steering lock device 1. Further, as shown in FIGS. 16 and 17, the bracket B is formed with a recess Ba that follows the shape (external appearance) of the case member 2 of the steering lock device 1, and the case member 2 is fitted into the recess Ba. has been done.
　しかるに、ステアリングロック装置１がブラケットＢに取り付けられた状態において、ソレノイドＳのコイルＣに対して通電または通電の停止を行うことにより、ロックバーＲが回動軸Ｎと略平行な方向（上下方向）に移動するよう構成されている。そして、ロックバーＲが上方に向かって前進することにより突出状態となると、図１５に示すように、当該ロックバーＲの先端部が外筒部Ｔの下部において突出形成された突出部Ｔａに係止してステアリングロックが行われるとともに、ロックバーＲが下方に向かって後退することにより没入状態となると、ロックバーＲの先端部が突出部Ｔａから離間してステアリングロックが解除されることとなる。 However, when the steering lock device 1 is attached to the bracket B, by energizing or de-energizing the coil C of the solenoid S, the lock bar R is moved in a direction substantially parallel to the rotation axis N (vertical direction). ). Then, when the lock bar R moves upward and enters the protruding state, the tip end of the lock bar R engages with the protruding part Ta protrudingly formed at the lower part of the outer cylindrical part T, as shown in FIG. When the steering wheel is stopped and the steering is locked, and the lock bar R is retracted downward to enter the retracted state, the tip of the lock bar R is separated from the protrusion Ta and the steering lock is released. .
　本実施形態に係るステアリングロック装置１によれば、車両のフロントフォークＤを連結するブラケットＢに取り付けられたので、ブラケットＢを利用してステアリングロック装置１をステアリング近傍に容易に配置することができるとともに、ステアリングロック装置１の取り付け位置やステアリング近傍のレイアウトの自由度を向上させることができる。 According to the steering lock device 1 according to the present embodiment, since it is attached to the bracket B that connects the front fork D of the vehicle, the steering lock device 1 can be easily placed near the steering wheel using the bracket B. At the same time, it is possible to improve the degree of freedom in the mounting position of the steering lock device 1 and the layout in the vicinity of the steering wheel.
　また、本実施形態によれば、ステアリングロック装置１を取り付けるための部材が不要となるため、製造コストの低下を図ることができ、さらに、強度及び剛性の高いブラケットＢにステアリングロック装置１を取り付けるので、ステアリングロック装置１を簡素化及び軽量化することができる。さらに、本実施形態によれば、ステアリング近傍のワイヤーハーネス配策の自由度を向上させることができる。すなわち、ステアリング近傍には、ハンドルバーＪに取り付けられる電装品のワイヤーハーネスが配策されるが、ブラケットＢにステアリングロック装置１を取り付けることで、ワイヤーハーネスの配策のためのガイド部材や保護部材の配置の自由度を増したり、或いはこれらの部材を廃止したりすることができる。 Further, according to the present embodiment, since no member is required for attaching the steering lock device 1, manufacturing costs can be reduced, and the steering lock device 1 is attached to the bracket B having high strength and rigidity. Therefore, the steering lock device 1 can be simplified and lightened. Furthermore, according to the present embodiment, the degree of freedom in arranging the wire harness near the steering wheel can be improved. That is, the wire harness of the electrical equipment attached to the handlebar J is routed near the steering wheel, but by attaching the steering lock device 1 to the bracket B, a guide member and a protective member for routing the wire harness are routed. It is possible to increase the degree of freedom in the arrangement of these members, or to eliminate these members.
　さらに、ブラケットＢにケース部材２の形状に倣った凹部Ｂａが形成され、当該凹部Ｂａにケース部材２が嵌入されるとともに、ロックバーＲは、上方に向かって前進することにより突出状態となってステアリングロックを行わせるとともに、下方に向かって後退することにより没入状態となってステアリングロックを解除するので、ステアリングロック装置１をブラケットに安定して固定させることができるとともに、ロックバーＲを円滑に上下させてステアリングロック及びその解除を行わせることができる。また、強度及び剛性の高いブラケットＢにステアリングロック装置１のケース部材２を嵌入させるので、ステアリングロック装置１の強度及び剛性をブラケットＢに依存することができ、ステアリングロック装置１をより簡素化且つ軽量化することができる。 Further, a recess Ba that follows the shape of the case member 2 is formed in the bracket B, and the case member 2 is fitted into the recess Ba, and the lock bar R is moved upward to be in a protruding state. The steering lock is locked and the steering lock is released by retracting downward, so that the steering lock device 1 can be stably fixed to the bracket and the lock bar R can be moved smoothly. It can be moved up and down to lock and release the steering wheel. Furthermore, since the case member 2 of the steering lock device 1 is fitted into the bracket B, which has high strength and rigidity, the strength and rigidity of the steering lock device 1 can be made to depend on the bracket B, and the steering lock device 1 can be simplified and It can be made lighter.
　またさらに、ロックバーＲを突出状態で保持する付勢部材５と、コイルＣへの通電により生じる磁力及び永久磁石（Ｍａ、Ｍｂ）の磁力により変位可能なプランジャＰを有するとともに、プランジャＰがロックバーＲと連結されて永久磁石（Ｍａ、Ｍｂ）の磁力により当該ロックバーＲを没入状態で保持する自己保持型ソレノイドＳとを具備したので、ソレノイドでロックバーＲを移動させることができるとともに、コイルＣに通電することなくロックバーＲの突出状態及び没入状態を保持することができる。 Furthermore, it has a biasing member 5 that holds the lock bar R in a protruding state, and a plunger P that can be displaced by the magnetic force generated by energizing the coil C and the magnetic force of the permanent magnets (Ma, Mb), and the plunger P is locked. Since the self-holding solenoid S is connected to the bar R and holds the lock bar R in a retracted state by the magnetic force of the permanent magnets (Ma, Mb), the lock bar R can be moved by the solenoid. The protruding state and retracted state of the lock bar R can be maintained without energizing the coil C.
　加えて、プランジャＰとロックバーＲとを略直交する方向に連結し、プランジャＰの変位方向に対して略直交する方向にロックバーＲを移動させる連結部材６を具備したので、プランジャＰの変位方向とロックバーＲの移動方向とを容易に異ならせることができ、車両のステアリング近傍におけるレイアウトの自由度をより向上させることができる。なお、本実施形態においては、プランジャＰの移動方向とロックバーＲの移動方向とが略直交しているが、平行な方向であってもよく、直交とは異なる所定角度有した方向であってもよい。 In addition, since the connecting member 6 is provided which connects the plunger P and the lock bar R in a direction substantially orthogonal to each other and moves the lock bar R in a direction substantially orthogonal to the displacement direction of the plunger P, the displacement of the plunger P is controlled. The direction of movement of the lock bar R can be easily made different from that of the lock bar R, and the degree of freedom in layout near the steering wheel of the vehicle can be further improved. In the present embodiment, the moving direction of the plunger P and the moving direction of the lock bar R are substantially perpendicular to each other, but they may be parallel directions, or may be directions having a predetermined angle different from orthogonal directions. Good too.
　また、自己保持型ソレノイドＳは、プランジャＰを収容しつつ永久磁石（Ｍａ、Ｍｂ）が取り付けられたパイプ状部材１０を有するので、プランジャＰの変位を円滑に行わせることができるとともに、永久磁石（Ｍａ、Ｍｂ）を所定の位置に確実に取り付けることができる。さらに、検出手段１３は、ロックバーＲと連動可能に取り付けられた接点７と、接点７との接触位置に応じた電気回路が形成される接触板とを有するとともに、接点７と接触板との間に形成された電気回路に基づいてロックバーＲの位置を検出可能とされたので、ロックバーＲの位置決め確認のためのセンサを不要とすることができ、製造コストを抑制することができる。 Furthermore, since the self-holding solenoid S has a pipe-shaped member 10 that accommodates the plunger P and is attached with permanent magnets (Ma, Mb), the plunger P can be smoothly displaced, and the permanent magnet (Ma, Mb) can be reliably attached to a predetermined position. Furthermore, the detection means 13 includes a contact 7 attached to the lock bar R so as to be interlocked with the lock bar R, and a contact plate on which an electric circuit is formed according to the contact position with the contact 7, and a contact plate between the contact 7 and the contact plate. Since the position of the lock bar R can be detected based on the electric circuit formed therebetween, a sensor for confirming the position of the lock bar R can be eliminated, and manufacturing costs can be suppressed.
　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、図１８～２０に示すように、鞍乗り型の大型車両に取り付けられるものであってもよい。この場合、上記実施形態と同様、ハンドルバーＪ、ハンドルバーＪの操作に伴って回転する回動軸Ｎ、および回動軸Ｎを収容する外筒部Ｔにより車両のステアリングＷが構成されるとともに、ステアリングロック装置１は、フロントフォークＤを連結するブラケットＡ（アンダーブラケット）の下部に取り付けられている。 Although the present embodiment has been described above, the present invention is not limited thereto, and may be attached to a large saddle type vehicle, for example, as shown in FIGS. 18 to 20. In this case, as in the above embodiment, the steering W of the vehicle is configured by the handlebar J, a rotation axis N that rotates with the operation of the handlebar J, and an outer cylinder part T that accommodates the rotation axis N. , the steering lock device 1 is attached to the lower part of a bracket A (under bracket) that connects a front fork D.
　しかるに、ステアリングロック装置１がブラケットＡに取り付けられた状態において、ソレノイドＳのコイルＣに対して通電または通電の停止を行うことにより、ロックバーＲが回動軸Ｎと略平行な方向（上下方向）に移動するよう構成されている。そして、ロックバーＲが上方に向かって前進することにより突出状態となると、図２０に示すように、当該ロックバーＲの先端部が外筒部Ｔの下部において突出形成された突出部Ｔａに係止してステアリングロックが行われるとともに、ロックバーＲが下方に向かって後退することにより没入状態となると、ロックバーＲの先端部が突出部Ｔａから離間してステアリングロックが解除されることとなる。 However, when the steering lock device 1 is attached to the bracket A, by energizing or de-energizing the coil C of the solenoid S, the lock bar R is moved in a direction substantially parallel to the rotation axis N (vertical direction). ). Then, when the lock bar R advances upward and enters the protruding state, the tip end of the lock bar R engages with the protruding part Ta protrudingly formed at the lower part of the outer cylindrical part T, as shown in FIG. When the steering wheel is stopped and the steering is locked, and the lock bar R is retracted downward to enter the retracted state, the tip of the lock bar R is separated from the protrusion Ta and the steering lock is released. .
　さらに、本実施形態に係るステアリングロック装置１は、ロックバーＲの駆動源として自己保持型ソレノイドＳが使用されているが、例えば永久磁石（Ｍａ、Ｍｂ）を具備しない他の形態のソレノイドＳ、或いはモータなど他の駆動源を使用してもよい。なお、本実施形態においては、二輪車に適用されているが、他の形態の車両に適用してもよい。 Furthermore, although the steering lock device 1 according to the present embodiment uses a self-holding solenoid S as a drive source for the lock bar R, for example, other types of solenoid S that do not include permanent magnets (Ma, Mb), Alternatively, other driving sources such as a motor may be used. Note that although this embodiment is applied to a two-wheeled vehicle, it may be applied to other types of vehicles.
　ロックバーが車両のステアリングの回動軸と略平行な方向に移動可能に取り付けられたステアリングロック装置であれば、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としてもよい。 As long as the lock bar is attached movably in a direction substantially parallel to the rotation axis of the steering wheel of the vehicle, the steering lock device may have a different external shape or may have other functions.
