The applicant (the inventors, etc.) has proposed a water vehicle that steers by moving the propulsion device to the left and right (see Patent Document 1).
JP 2005-280627 A

特許文献１においては、艇体６０（以下に特許文献１の公報中の符号を示す。以下同じ）に推進装置５０（船外機）を前後方向（横向き）の支軸１２を中心とした揺動自在に連結し、艇体の左右の傾き運動を、縦向きのステアリングシャフト５３を中心として操舵自在に支持された推進装置５０の操舵作動に変換する変換機構３０を備える。 In Patent Document 1, a propulsion device 50 (outboard motor) is swung around a support shaft 12 in the front-rear direction (lateral direction) on a hull 60 (hereinafter, the reference numerals in Patent Document 1 are shown below). A conversion mechanism 30 is provided that is movably connected and converts the horizontal tilting motion of the hull into a steering operation of the propulsion device 50 that is supported so as to be steerable around a vertical steering shaft 53.

変換機構３０は、艇体６０側の支軸１２の上方に設けた操作杆１６と、推進装置５０側支軸１２の上方に設けた支持杆１７と、支持杆１７にピン１９（揺動支軸）で揺動自在に枢支した揺動杆１８とを備える。艇体６０側の操作杆１６は、揺動杆１８のピン１９よりも下方位置で揺動杆１８にピン２１で枢着し、揺動杆１８の揺動支軸１９の上方の部分に長孔２０を設け、該長孔２０に、推進装置５０の上部の前面に前後方向（横向き）に突設したピン５４を係合して構成されている。 The conversion mechanism 30 includes an operation rod 16 provided above the support shaft 12 on the hull 60 side, a support rod 17 provided above the support device 12 on the propulsion device 50 side, and a pin 19 (swing support) on the support rod 17. And a rocking rod 18 pivotally supported by a shaft). The operation rod 16 on the hull 60 side is pivotally attached to the swing rod 18 with a pin 21 at a position lower than the pin 19 of the swing rod 18, and is long on a portion above the swing support shaft 19 of the swing rod 18. A hole 20 is provided, and the long hole 20 is configured by engaging a pin 54 protruding in the front-rear direction (lateral direction) on the front surface of the upper portion of the propulsion device 50.

以上においては、重心移動などによる艇体６０の左右の傾き運動で、支軸１２の上方に設けられた操作杆１６は、第１段目として、艇体６０の傾き運動側と同じ側に傾く。
この傾き運動は、支持杆１７にピン１９を中心として、揺動自在に支持された揺動杆１８の操作杆１６の運動方向とは逆向きの第２段目の運動に変換され、揺動杆１８の上部の運動を、揺動杆１８の上部に長孔２０を介して係合したピン５４により推進装置５０に伝達し、推進装置５０を操作杆１６とは逆方向にステアリングシャフト５３を中心として回動させ、操舵を行う。 In the above, the operation rod 16 provided above the support shaft 12 is tilted to the same side as the tilting motion side of the hull 60 as the first step by the tilting motion of the hull 60 left and right due to the movement of the center of gravity. .
This tilting motion is converted into a second stage motion that is opposite to the motion direction of the operating rod 16 of the swinging rod 18 that is supported by the supporting rod 17 about the pin 19 so as to be swingable. The movement of the upper portion of the rod 18 is transmitted to the propulsion device 50 by the pin 54 engaged with the upper portion of the swing rod 18 through the long hole 20, and the propulsion device 50 is moved in the direction opposite to the operation rod 16. Turn around the center and steer.

以上の従来技術は、艇体６０の傾きに応じてその傾き運動の第１段目として取り出すための操作杆１６が、中立位置から艇体６０の傾く側に偏寄し（操作杆１６は艇体側の同じ側に傾く）、この偏寄とは逆側（操作杆の動きとは反対側の動き）に運動を変換して推進装置５０の第２段目以降の運動として伝達する必要がある。この結果、構造の複雑化、その分の部品点数の増加、製造コストが嵩むなどの不利がある。 In the above prior art, the operating rod 16 for taking out as the first stage of the tilting motion according to the inclination of the hull 60 is offset from the neutral position to the inclined side of the hull 60 (the operating rod 16 is the boat). It is necessary to convert the movement to the opposite side (movement opposite to the movement of the operating rod) and transmit it as the movement after the second stage of the propulsion device 50. . As a result, there are disadvantages such as a complicated structure, an increase in the number of parts, and an increase in manufacturing cost.

特に特許文献１の技術は、艇体６０の傾きを２段目の揺動で伝達する揺動杆１８と、推進装置５０の係合は、揺動杆１８の長孔２０と推進装置５０のピンとの係合であり、揺動杆１８と艇体側の操作子１６とはピン２１で連結されているので、変換機構３０は艇体６０、推進装置５０を揺動可能であるが連結した状態にある。
従って、舵取り操作に有効な範囲を超えても連結状態を維持することになり、艇体の左右方向の大きな傾きが、推進機の無用な左右方向の大きな傾動をもたらす。
本発明は、主に以上の問題点を解決すべくなされたものである。 In particular, in the technique of Patent Document 1, the engagement between the swing rod 18 that transmits the inclination of the hull 60 by the second swing and the propulsion device 50 is performed between the long hole 20 of the swing rod 18 and the propulsion device 50. Since it is engaged with the pin and the swing rod 18 and the hull-side operation element 16 are connected by the pin 21, the conversion mechanism 30 can swing the hull 60 and the propulsion device 50, but in a connected state. It is in.
Accordingly, the connected state is maintained even if the effective range for the steering operation is exceeded, and a large horizontal tilt of the hull causes a large unnecessary horizontal tilt of the propulsion device.
The present invention has been made mainly to solve the above problems.

駆動部４１は、側面視が略Ｚ形で、上部４１ａを基板７の中央部下部にボルト４３，４３で固着し、後方に段状に突出し、且つ基板７の下縁７ａの下方に垂下した板状の本体部４１ｂの左右方向中央部には、下方に少し拡開する形状の略逆Ｖ形の係合溝４２が形成されている。 6 is a cross-sectional view taken along line 6-6 in FIG. 5, and FIG. 7 is a cross-sectional view taken along line 7-7 in FIG.
A drive part 41 (drive arm part) constituting the first operating element of the conversion mechanism 40 (oscillating turning mechanism) so as to project downward downward at the center in the left-right direction of the rear surface of the board 7 on the hull side. ) Is fixed and installed.
The drive part 41 is substantially Z-shaped in a side view, and the upper part 41a is fixed to the lower part of the center part of the board 7 with bolts 43, 43, protrudes rearwardly, and hangs below the lower edge 7a of the board 7 A substantially inverted V-shaped engagement groove 42 having a shape that slightly expands downward is formed at the center in the left-right direction of the plate-like main body 41b.

この係合溝４２の上端部４２ａは弧状であり、左右の内縁４２ｂ，４２ｂは、下方にゆくに従って順次その間隔を少し拡がり、下端部４２ｃ，４２ｃは弧状であり、また内縁４２ｂ，４２ｂは、向かい合うよう内側に対称的に突出する弧状の断面である。 The upper end portion 42a of the engagement groove 42 is arcuate, the left and right inner edges 42b and 42b are gradually widened as they move downward, the lower end portions 42c and 42c are arcuate, and the inner edges 42b and 42b are It is an arcuate cross section protruding symmetrically inward so as to face each other.

一方、船外機１０を回転自在に支持する支持外筒部２６下方に位置するギヤケース２２の上部には、揺動操舵機構４０の第２操作子を構成する従動部４４を固着する。
従動部４４は、図７に示したように幅広の基部４４ａの後部に弧状で二股状の取付部４４ｂ，４４ｂを備え、この部分をギヤケース２２の上部２２ａの前半部外周に溶接等して固着し、前方に突出するように設ける。 On the other hand, a follower 44 that constitutes the second operating element of the swing steering mechanism 40 is fixed to the upper portion of the gear case 22 positioned below the support outer cylinder portion 26 that rotatably supports the outboard motor 10.
As shown in FIG. 7, the driven portion 44 includes arcuate and bifurcated mounting portions 44b and 44b at the rear portion of the wide base portion 44a, and this portion is fixed to the outer periphery of the front half of the upper portion 22a of the gear case 22 by welding or the like. And provided so as to protrude forward.

従動部４４は、基部４４ａの先端部に、断面円形のスティック状の係合部４５が突設されており、該係合部４５を前記した駆動部４１の係合溝４２に係合する。係合部４５の先端部４５ａは半球状である。
この状態を図２、図５、図６、図７で示した。 The follower 44 is provided with a stick-like engagement portion 45 having a circular cross section at the tip of the base portion 44a, and engages the engagement portion 45 with the engagement groove 42 of the drive portion 41 described above. The tip 45a of the engaging part 45 is hemispherical.
This state is shown in FIG. 2, FIG. 5, FIG. 6, and FIG.

図８〜図１０は、重心移動などにより、艇体の傾き運動で艇体操舵作動を示す縦断面図で、艇体の中間部を縦断し、前方からみた図であり、図の手前側が進行方向の前方であり、図の奥側が進行方向の後方である。
図８は、艇体が水平な状態を示す図、図９は、艇体を左に傾動させ、左に転舵する状態を示す図（図では、前後が逆なので左右が逆に表れる）、図１０は、艇体を右に傾動させ、右に転舵する状態を示す図（同様に、図では前後が逆なので左右が逆に表れる）である。 FIGS. 8 to 10 are longitudinal sectional views showing the hull steering operation by the tilting motion of the hull due to the movement of the center of gravity, etc., and are longitudinal views of the middle part of the hull, viewed from the front. It is the front of the direction, and the back side of the figure is the rear of the traveling direction.
FIG. 8 is a diagram showing a state in which the hull is horizontal, and FIG. 9 is a diagram showing a state in which the hull is tilted to the left and steered to the left (in the figure, the left and right appear oppositely because the front and rear are reversed), FIG. 10 is a diagram showing a state in which the hull is tilted to the right and steered to the right (similarly, since the front and rear are reversed in the figure, the left and right appear reversely).

図８は、艇体１が水平な直進状態を示す図で、艇体１は水平な状態にあり、船外機１０のプロペラ１８は真後ろを向き、船外機１０の推進力で直進する。図において４ｄは、左右の横枠部４，４間に架設されたクロス部材である。
操縦者は艇体１の上で重心移動させることで、艇体１は左右に傾動する。この際、船外機１０は、左右のフロート９，９の作用で鉛直に保持される。 FIG. 8 is a view showing a state in which the hull 1 is in a horizontal straight state. The hull 1 is in a horizontal state, and the propeller 18 of the outboard motor 10 faces directly behind and moves straight by the propulsive force of the outboard motor 10. In the figure, reference numeral 4d denotes a cross member constructed between the left and right horizontal frame parts 4 and 4.
When the pilot moves the center of gravity on the hull 1, the hull 1 tilts left and right. At this time, the outboard motor 10 is held vertically by the action of the left and right floats 9 and 9.

図９は、艇体１を図の右側に傾けた状態を示し、艇体１の図の右方向への傾斜で、艇体に一体化した基板７は、支軸３２を中心として図の右方向に揺動し、一方、船外機１０は水平状態（操舵軸が鉛直）に保持されている。
艇体１の右方向への傾きで、これと一体化している基板７は同方向に傾き、基板７の中央部下部に垂下設置した駆動部４１は、艇体の傾き方向とは反対側に、偏寄するように一体的に傾き運動する。 FIG. 9 shows a state in which the hull 1 is tilted to the right in the figure, and the board 7 integrated with the hull is tilted to the right in the figure. On the other hand, the outboard motor 10 is held in a horizontal state (the steering shaft is vertical).
When the hull 1 is tilted in the right direction, the board 7 integrated with the hull 1 is tilted in the same direction, and the drive unit 41 suspended from the lower center of the board 7 is on the opposite side of the hull tilt direction. , Tilt and move together as if they are biased.

駆動部４１の係合溝４２には、前記したように船外機１０のギヤケース２２に、前方に突設した従動部４４のスティック状係合部４５が図６、図７に示すように係合しており、駆動部４１の傾き運動により係合部４５は同じ方向、即ち艇体の傾き方向とは反対側に、偏寄するように揺動する。
係合部４５の係合溝４２に対する係合は、係合部４５が先端部４５ａが半球状の丸棒部材であり、係合溝４２は下開きの逆Ｖ形であり、左右の内側面４２ｂ，４２ｂが断面弧状なので、駆動部４１の傾き運動に際し、係合溝４２内で係合部４５は円滑に摺接しつつ摺動し、駆動部４１が運動した方向に従動部４４を運動させる。 As shown in FIGS. 6 and 7, the engaging groove 42 of the drive unit 41 has a stick-like engaging portion 45 of a driven portion 44 projecting forward from the gear case 22 of the outboard motor 10 as described above. The engaging portion 45 swings so as to be biased in the same direction, that is, on the side opposite to the inclination direction of the hull.
The engagement portion 45 is engaged with the engagement groove 42 in a manner that the engagement portion 45 is a hemispherical round bar member having a tip end portion 45a, and the engagement groove 42 is a reverse V-shape with a downward opening. Since 42b and 42b are arc-shaped in cross section, when the drive part 41 tilts, the engagement part 45 slides smoothly in sliding contact within the engagement groove 42, and the driven part 44 moves in the direction in which the drive part 41 has moved. .

船外機１０は、支持板８に対して、スターンブラケット２４を介して縦向きの支持外筒部２６に、回転自在（操舵自在）に支持されており、従動部４４は、ギヤケース２２の上部に一体的に連結されているので、船外機１０は従動部４４の運動に追従して支持外筒部２６に嵌合されている筒軸状のエクステンションケース２１を中心と鉛直軸回りに回転する。
この結果、艇体１が傾斜した方向に船外機１０は揺動し、艇体を傾けた方向に転舵されることとなる。 The outboard motor 10 is rotatably supported (steered) by a vertically supporting outer cylinder portion 26 with respect to the support plate 8 via a stern bracket 24, and the driven portion 44 is an upper portion of the gear case 22. The outboard motor 10 follows the movement of the follower 44 and rotates around the vertical axis around the cylindrical extension case 21 fitted to the support outer cylinder 26. To do.
As a result, the outboard motor 10 swings in the direction in which the hull 1 is tilted, and is steered in the direction in which the hull is tilted.

図６は、艇体の傾き運動による駆動部４１の運動、駆動部４１の傾き運動による従動部４４の運動を鎖線で示している。
図６の中立位置Ａから図の左側に駆動部４１が傾動することで、従動部４４の係合部４５が係合溝４２内で図の左方に摺動して移動している状態が示され、転舵位置Ｂとなる。従動部４２の係合部４５は船外機１０側に配設されており、前記したように水平状態に保持されているので、水平なラインＬに沿って同一平面内で図の左方に移動する。 FIG. 6 shows the movement of the driving unit 41 by the tilting motion of the hull and the movement of the driven unit 44 by the tilting motion of the driving unit 41 by chain lines.
When the drive part 41 tilts from the neutral position A in FIG. 6 to the left side in the figure, the engagement part 45 of the driven part 44 slides and moves to the left in the figure in the engagement groove 42. As shown in FIG. Since the engaging portion 45 of the driven portion 42 is disposed on the outboard motor 10 side and is held in the horizontal state as described above, it is located on the left side of the drawing within the same plane along the horizontal line L. Moving.

図１０は、艇体１を左側に傾けた状態を示し、艇体１の図の左方向への傾斜で、艇体１側の基板７はこの方向に傾斜し、これに付設した駆動部４１は図の右方向に偏寄するように傾く。これにより従動部４４の係合部４５は係合溝４２の右方向への運動で右方向に運動させられ、船外機１０はステアリングシャフト（エクステンションケース２１）を中心として図の左方向に揺動、操舵され、艇体１を図９とは逆に左方向に転舵させることとなる。 FIG. 10 shows a state in which the hull 1 is tilted to the left side. When the hull 1 is tilted leftward in the figure, the board 7 on the hull 1 side is tilted in this direction, and a drive unit 41 attached thereto. Tilts to the right in the figure. As a result, the engagement portion 45 of the driven portion 44 is moved to the right by the movement of the engagement groove 42 to the right, and the outboard motor 10 swings to the left in the figure around the steering shaft (extension case 21). The hull 1 is moved and steered, and the hull 1 is steered in the left direction as opposed to FIG. 9.

以上のように、艇体１の操縦に際し、操縦者の重心移動で艇体１を左右に傾斜させることで、船外機１０（推進装置）を揺動転舵機構４０を介して転舵させることができる。
従って、船外機１０の推進力で推進しつつ、艇体１の重心移動で、艇体が傾斜する方向に船外機の転舵を行うことができる。 As described above, when maneuvering the hull 1, the outboard motor 10 (propulsion device) is steered via the oscillating turning mechanism 40 by tilting the hull 1 left and right by moving the center of gravity of the operator. Can do.
Accordingly, the outboard motor can be steered in the direction in which the hull is inclined by moving the center of gravity of the hull 1 while propelling with the propulsive force of the outboard motor 10.

図１１〜図１６は、艇体の過大な傾きによる揺動転舵機構の解除作動を示す説明図であり、これらの図面で説明する。
図１１は、図８に相当する図で、艇体の傾き運動で艇体操舵作動を示す縦断面図であり、艇体が水平な状態から傾き運動を説明する図、図１２は、図１１に相当する図で、艇体側の後部を含む推進装置を斜め後方から見た図である。 FIGS. 11-16 is explanatory drawing which shows cancellation | release operation | movement of the rocking | swiveling steering mechanism by the excessive inclination of a hull, and demonstrates with these drawings.
FIG. 11 is a view corresponding to FIG. 8 and is a longitudinal sectional view showing the hull steering operation by the tilting motion of the hull, illustrating the tilting motion from a horizontal state, and FIG. It is the figure equivalent to, and is the figure which looked at the propulsion apparatus containing the rear part of the hull side from diagonally back.

図１１の矢印（イ）に示すように図において艇体１が右を上となるように傾いたとしよう。図１２に示すように後方から見た斜視図として示しているので、艇体１は矢印（イ）のように右上がりに傾動する。 Assume that the hull 1 is tilted so that the right side is up in the figure as indicated by the arrow (A) in FIG. Since it is shown as a perspective view seen from the rear as shown in FIG. 12, the hull 1 tilts upward as shown by an arrow (A).

図１３は、図１１の図において、図１１から傾いた状態を示す図、図１４は、図１２の図において、図１２から傾いた状態を示す図である。
図１３では前記した矢印（イ）方向への艇体１の傾きで図の左側が上がり、右側が下がった状態（図９と同様の状態）を示す。 13 is a diagram showing a state tilted from FIG. 11 in the diagram of FIG. 11, and FIG. 14 is a diagram showing a state tilted from FIG. 12 in the diagram of FIG.
FIG. 13 shows a state where the left side of the figure is raised and the right side is lowered (the same state as FIG. 9) due to the inclination of the hull 1 in the direction of the arrow (A).

艇体１側の駆動部４１は、図１３に示す通り、艇体１の傾いた側とは反対方向に偏寄するように揺動し、船外機１０側の従動部４４は係合溝４２、係合部４５との係合で同じ方向に揺動し、水平な状態に保持される船外機１０を、左方向にステアリングシャフトを構成するエクステンションケース２１を中心として回転させ、転舵する。
図１４に示したように、船外機１０は、クランクシャフト１２、駆動軸１５などを鉛直に保持したまま、艇体１は矢印方向に傾く。
艇体１の傾動の継続で矢印（ロ）方向に傾動を続行したとしよう。 As shown in FIG. 13, the drive unit 41 on the hull 1 side swings so as to be offset in the opposite direction to the inclined side of the hull 1, and the driven unit 44 on the outboard motor 10 side has an engagement groove. 42. The outboard motor 10 that swings in the same direction by the engagement with the engagement portion 45 and is held in a horizontal state is rotated about the extension case 21 that constitutes the steering shaft in the left direction, and steered. To do.
As shown in FIG. 14, in the outboard motor 10, the hull 1 tilts in the direction of the arrow while the crankshaft 12, the drive shaft 15 and the like are held vertically.
Suppose that the tilt of the hull 1 continues to tilt in the direction of the arrow (b).

図１５は、艇体が図１３の状態から更に傾き、揺動操舵機構４０は駆動部と従動部との係合が解除された状態を示し、図１６は、図１５の状態を後方から見た斜視図として示した図である。
艇体１の更なる揺動で、艇体１側の駆動部４１は、艇体の傾動方向と反対側に偏寄して更に傾動し、一方、船外機１０側の従動部４４は、係合溝４２の図６におけるＢの位置から更に上方への傾動でＣの位置に達し、従動部４４の係合部４５は水平状態（図６の水平線Ｌの位置）を保持しているので、駆動部４１の係合溝４２から離脱する。 FIG. 15 shows a state where the hull is further tilted from the state of FIG. 13 and the swing steering mechanism 40 is disengaged from the drive unit and the driven unit. FIG. 16 shows the state of FIG. It is the figure shown as a perspective view.
As the hull 1 is further swung, the drive unit 41 on the hull 1 side is further tilted by being offset to the opposite side of the hull tilt direction, while the follower 44 on the outboard motor 10 side is The engagement groove 42 is further tilted upward from the position B in FIG. 6 to reach the position C, and the engagement portion 45 of the driven portion 44 holds the horizontal state (position of the horizontal line L in FIG. 6). Then, it disengages from the engaging groove 42 of the drive part 41.

このように、駆動部４１の揺動、艇体１の傾きが過大となると、従動部４４の係合部４５が駆動部４１の係合溝４２から鎖線Ｃのように離脱し、駆動部４１と従動部４４との係合は解除されることとなる。
これにより、艇体１の過大な傾きは、駆動部４１から従動部４４に伝達されることがなく、船外機１０に艇体１の過大な傾きは伝達されない。 As described above, when the swinging of the driving unit 41 and the inclination of the hull 1 are excessive, the engaging portion 45 of the driven portion 44 is detached from the engaging groove 42 of the driving portion 41 as indicated by a chain line C, and the driving portion 41 And the driven portion 44 are disengaged.
As a result, an excessive inclination of the hull 1 is not transmitted from the drive unit 41 to the driven unit 44, and an excessive inclination of the hull 1 is not transmitted to the outboard motor 10.

以上の駆動部４１の係合溝４２から従動部４４の係合部４５が離脱する係合解除作用であるが、係合溝４２の開放部両下端部４２ｃ，４２ｃは前記したように弧状であり、一方、従動部４４の係合部４５は丸棒状である。従って、係合溝４２から係合部４５が離脱する際、引っ掛かることなく、円滑に、迅速に係合状態は解除されることとなる。 The above-described engagement releasing action is to release the engaging portion 45 of the driven portion 44 from the engaging groove 42 of the driving portion 41. However, the open portion both lower end portions 42c and 42c of the engaging groove 42 are arcuate as described above. On the other hand, the engaging portion 45 of the driven portion 44 has a round bar shape. Therefore, when the engagement portion 45 is disengaged from the engagement groove 42, the engagement state is released smoothly and quickly without being caught.

また図７で示したように、中立位置Ａから鎖線で示した通り駆動部４１が移動し、Ｂに示すように、従動部４４がこの方向に揺動した場合、係合溝４２の内側面４２ｂ，４２ｂの断面が弧状であり、また従動部４４の係合部４５が丸棒なので、図６に示したように、係合部は係合溝４２内において、相対的な下方に移動及び水平方向おける係合溝４２内の前後方向の摺動は円滑になされる。 As shown in FIG. 7, when the drive unit 41 moves from the neutral position A as shown by the chain line and the driven unit 44 swings in this direction as shown in B, the inner surface of the engagement groove 42 Since the cross sections of 42b and 42b are arcuate and the engaging portion 45 of the driven portion 44 is a round bar, the engaging portion moves and moves relatively downward in the engaging groove 42 as shown in FIG. The sliding in the front-rear direction in the engaging groove 42 in the horizontal direction is performed smoothly.

このように、艇体１の過大な傾動に際し、船外機１を水平状態の保持したまま、艇体１と船外機１０との連結を解除し、艇体１が大きく傾動することが許容され、船外機１０は、艇体１に操舵範囲を超える傾動が生じたとしても対処することができる。
このように艇体１と船外機１０との間に介設される揺動転舵機構４０は、迅速に、円滑に、確実に、艇体１の設定された傾き角度（即ち、艇体１とともに傾く駆動部４１の係合溝４２の設定された角度）で係合を解除する。 As described above, when the hull 1 is excessively tilted, the hull 1 and the outboard motor 10 are allowed to be tilted greatly by releasing the connection between the hull 1 and the outboard motor 10 while keeping the outboard motor 1 in a horizontal state. Thus, the outboard motor 10 can cope with even if the hull 1 is tilted beyond the steering range.
Thus, the swing steering mechanism 40 interposed between the hull 1 and the outboard motor 10 can quickly, smoothly and reliably set the tilt angle of the hull 1 (that is, the hull 1). At the same time, the engagement is released at a set angle of the engaging groove 42 of the drive unit 41 which is inclined.

爾後、艇体１を通常姿勢に復帰させた際の揺動転舵機構４０の再係合であるが、図６の逆の作動、即ち、Ｃの位置から図の右方向に係合部４５を移動させ、基板７を実線方向に揺動させることで、係合部４５は図のＢのように係合溝４２に係合し、中立位置Ａの位置に復帰させることができる。
この際、前記したように、係合溝４２の開放部両下端部４２ｃ，４２ｃは弧状であり、一方、従動部４４の係合部４５は丸棒状であり、仍って、係合溝４２に係合部４５が係合する際、引っ掛かることなく、円滑に、迅速、確実、容易に係合状態に移行させることができる。 After the dredging, the swing steering mechanism 40 is re-engaged when the hull 1 is returned to the normal posture, but the reverse operation of FIG. 6, that is, the engagement portion 45 is moved from the position C to the right in the figure. By moving the substrate 7 and swinging the substrate 7 in the direction of the solid line, the engaging portion 45 can be engaged with the engaging groove 42 as shown in B in the figure and returned to the neutral position A.
At this time, as described above, both the lower end portions 42c and 42c of the opening portion of the engaging groove 42 are arc-shaped, while the engaging portion 45 of the driven portion 44 is a round bar shape. When the engagement portion 45 is engaged with the engagement portion 45, the engagement portion 45 can be smoothly, quickly, reliably, and easily shifted to the engagement state without being caught.

以上において、揺動転舵装置４０による艇体１と推進装置１０との係合、離脱作動であるが、図６は、艇体１が鎖線で示すように左側が上がり、左側が下がった傾動状態を示し、艇体１と推進装置１０との間の係合の離脱は、図では艇体１の角度θの傾動を越えた角度（図６のＤを越えた位置）で、係合溝４２から係合部４５が離脱し、艇体１側の駆動部４１と推進装置１０側の従動部との係合が解除される。 The above is the engagement and disengagement operation of the hull 1 and the propulsion device 10 by the swing steering device 40. FIG. 6 shows a tilted state in which the hull 1 is raised on the left side and the left side is lowered as indicated by the chain line. The engagement disengagement between the hull 1 and the propulsion device 10 is shown in the figure at an angle exceeding the tilt of the angle θ of the hull 1 (position beyond D in FIG. 6). The engagement portion 45 is disengaged and the engagement between the driving portion 41 on the hull 1 side and the driven portion on the propulsion device 10 side is released.

上記したＤの位置を越えると、前記したように係合溝４２の開放部両下端部４２ｃ，４２ｃが弧状で、従動部４４の係合部４５は断面円形であり、係合溝４２に係合部４５が引っ掛かることなく、円滑に、迅速、確実に双方の係合は解除され、艇体１と推進装置１０との間に介設された揺動転舵機構４０は解除される。
駆動部４１と従動部４４との解除角度θは、駆動部４１の係合溝の長さにより任意に設定することができ、艇体の種類などで適宜最適の角度に設定する。 When the position D is exceeded, as described above, both the lower end portions 42c and 42c of the open portion of the engaging groove 42 are arcuate, and the engaging portion 45 of the driven portion 44 is circular in cross section. Both the engagements are smoothly, quickly and reliably released without the joint portion 45 being caught, and the swing steering mechanism 40 interposed between the hull 1 and the propulsion device 10 is released.
The release angle θ between the drive unit 41 and the driven unit 44 can be arbitrarily set according to the length of the engagement groove of the drive unit 41, and is appropriately set to an optimum angle depending on the type of hull.
