上述した操作レバー８、第１の回動体１０、第２の回動体１１、第１の連結体１８、第２の連結体２３との関係を図７を参照して説明すると、操作レバー８は、本体ボディー２５に取り付けられる芯棒(ピン)２６に回動自在に支持され、操作レバー８に力が作用しない状態にあっては、図４に示す中立状態にある。本体ボディー２５は、スライドドア１ｃ１に取り付けられている。操作レバー８の他端部には、第１の回動体１０、第２の回動体１１を回動自在に支持する支持部８ｂ、突起８ｃ、８ｄを有している。
操作レバー８を一方の回動方向（図４、スライドドア１ｃ１の内側Ｉから見て反時計回りの方向）に回動させると、突起８ｃにより第１の回動体１０を回動させ、逆に、操作レバー８を他方の回動方向（図４、スライドドア１ｃ１の内側Ｉから見て時計回りの方向）に回動させると、突起８ｄにより第２の回動体１１を回動させるようになっている。
図７に示す２７は、高さ調整用のワッシャー、２８はキーシリンダー、２９は座金、
３０は、操作レバー８の動きをロックするロック金物(ロック用の駒)、３１は裏カバーである。なお、図示しないキーを使用して、ロック金物３０を図１５記載から図１６記載のように回動させて、略Ｖ字形状のロック金物３０のそれぞれの先端と突起８ｃ、８ｄとを係合させて、第１の回動体１０、第２の回動体１１の回動を拘束し、操作レバー８の移動を阻止することができる。 The relationship between the operation lever 8, the first rotating body 10, the second rotating body 11, the first connecting body 18, and the second connecting body 23 will be described with reference to FIG. In a state in which a force is not applied to the operation lever 8 supported by a core rod (pin) 26 attached to the main body body 25 so as to be rotatable, it is in a neutral state shown in FIG. The main body 25 is attached to the slide door 1c1. The other end portion of the operation lever 8 has a support portion 8b and protrusions 8c and 8d that rotatably support the first rotating body 10 and the second rotating body 11.
When the operating lever 8 is rotated in one direction of rotation (a counterclockwise direction when viewed from the inside I of the sliding door 1c1 in FIG. 4), the first rotating body 10 is rotated by the protrusion 8c, and conversely. When the operating lever 8 is rotated in the other rotation direction (FIG. 4, clockwise direction when viewed from the inside I of the slide door 1c1), the second rotation body 11 is rotated by the protrusion 8d. ing.
7, 27 is a height adjusting washer, 28 is a key cylinder, 29 is a washer,
Reference numeral 30 is a lock hardware (locking piece) for locking the movement of the operation lever 8, and 31 is a back cover. The lock metal 30 is rotated as shown in FIGS. 15 to 16 by using a key (not shown) to engage the respective tips of the substantially V-shaped lock metal 30 with the protrusions 8c and 8d. Thus, the rotation of the first rotating body 10 and the second rotating body 11 can be restricted and the movement of the operation lever 8 can be prevented.

従って、図８に示すように、第１のストッパー１２に第１の係止突起１４が係止して、スライドドア１ｃ１で車体の開口部２(図１２参照)を閉めた状態を保持する。
第１のストッパー１２と第１の係止突起１４との係止状態は、操作レバー８の一方の回動方向（図９、スライドドア１ｃ１の内側Ｉから見て反時計回りの方向）の回動により、第１の回動体１０、第１の連結体１８を介して第１の係止突起１４の下方への移動により解除される(図９参照)。
そして、操作レバー８の一方の回動方向に力を作用させると、スライドドア１ｃ１が図９及び図１０に示す方向に移動する。スライドドア１ｃ１が移動すると、第２の係止突起１９の先端は、スライドドア１ｃ１による開口部２(図１２参照)を開ける移動方向に対して、下がり勾配１９ｂに形成されているため、下がり勾配１９ｂに第２のストッパー１３が当接し（図１０参照)、第２の付勢部材２１に抗して第２の係止突起１９が下方へ移動し、第２のストッパー１３を乗り越える。乗り越えた後は、図１１に示すように、第２の付勢部材２１により第２の係止突起１９が上方へ移動し、第２のストッパー１３に第２の係止突起１９が係止して、スライドドア１ｃ１で車体の開口部２(図１２参照)を開けた状態を保持することとなる。
次に、スライドドア１ｃ１で車体の開口部２(図１２参照)を開けた状態から閉じる状態にするには、操作レバー８の他方の回動方向（図１２、スライドドア１ｃ１の内側Ｉから見て時計回りの方向）の回動により、第２の回動体１１、第２の連結体２３を介して、第２の係止突起１９の下方への移動により解除される(図１２参照)。
そして、操作レバー８の他方の回動方向に力を作用させると、スライドドア１ｃ１が図１２に示す方向に移動する。スライドドア１ｃ１が移動すると、第１の係止突起１４の先端は、スライドドア１ｃ１による開口部２(図１２参照)を開ける移動方向に対して、下がり勾配１４ｂに形成されているため、下がり勾配１４ｂに第１のストッパー１２が当接し（図１３参照)、第１の付勢部材１６に抗して第１の係止突起１４が下方へ移動し、第１のストッパー１２を乗り越える。乗り越えた後は、図１４に示すように、第１の付勢部材１６により第１の係止突起１４が上方へ移動し、第１のストッパー１２に第１の係止突起１４が係止して、スライドドア１ｃ１で車体の開口部２(図１２参照)を閉じた状態を保持することとなる。 Therefore, as shown in FIG. 8, the first locking projection 14 is locked to the first stopper 12, and the state in which the opening 2 (see FIG. 12) of the vehicle body is closed by the slide door 1c1 is maintained.
The locking state of the first stopper 12 and the first locking protrusion 14 is determined by rotating the operating lever 8 in one rotational direction (counterclockwise direction as viewed from the inside I of the sliding door 1c1 in FIG. 9). The movement is released by the downward movement of the first locking projection 14 via the first rotating body 10 and the first connecting body 18 (see FIG. 9).
When a force is applied in one rotation direction of the operation lever 8, the slide door 1c1 moves in the direction shown in FIGS. When the sliding door 1c1 moves, the tip of the second locking projection 19 is formed with a descending slope 19b with respect to the moving direction of opening the opening 2 (see FIG. 12) by the sliding door 1c1, so the descending slope The second stopper 13 comes into contact with 19b (see FIG. 10), the second locking projection 19 moves downward against the second urging member 21, and gets over the second stopper 13. After getting over, as shown in FIG. 11, the second urging member 21 moves the second locking projection 19 upward, and the second locking projection 19 is locked to the second stopper 13. Thus, the state in which the opening 2 (see FIG. 12) of the vehicle body is opened by the slide door 1c1 is held.
Next, in order to change the opening 2 (see FIG. 12) of the vehicle body from the opened state to the closed state with the slide door 1c1, the other rotation direction of the operation lever 8 (see from the inside I of the slide door 1c1 in FIG. 12). Is released by the downward movement of the second locking projection 19 via the second rotating body 11 and the second connecting body 23 (see FIG. 12).
When a force is applied in the other rotation direction of the operation lever 8, the slide door 1c1 moves in the direction shown in FIG. When the slide door 1c1 moves, the tip of the first locking projection 14 is formed with a downward slope 14b with respect to the moving direction of opening the opening 2 (see FIG. 12) by the slide door 1c1, and therefore the downward slope The first stopper 12 comes into contact with 14b (see FIG. 13), and the first locking projection 14 moves downward against the first biasing member 16 to get over the first stopper 12. After getting over, as shown in FIG. 14, the first urging member 16 moves the first locking projection 14 upward, and the first locking projection 14 is locked to the first stopper 12. Thus, the sliding door 1c1 holds the vehicle body opening 2 (see FIG. 12) closed.

つまり、スライドドア１ｃ１で開口部２(図１２参照)を開ける方向は、操作レバー８の一方の回動方向（図９、スライドドア１ｃ１の内側Ｉから見て反時計回りの方向）であり、操作レバー８の一方の回動方向の回動により第１のストッパー１２と第１の係止突起１４との係止状態が解除され、解除後、スライドドア１ｃ１の開口部２(図１２参照)を開ける方向の移動が許容される（図８及び図９参照）。
該許容後、スライドドア１ｃ１を開口部２(図１２参照)が開くように移動させて、第２の係止突起１９が第２のストッパー１３に当接し、第２の付勢部材２１に抗して第２の係止突起１９が移動して（図１０参照）、スライドドア１ｃ１の開口部２(図１２参照)を開ける方向の移動が許容され、スライドドア１ｃ１が開口部２(図１２参照)を開くように移動させて第２の係止突起１９が第２のストッパー１３に非当接すると、第２の付勢部材２１により第２の係止突起１９が移動（図１１参照）し、該移動の後、スライドドア１ｃ１が開口部２(図１２参照)を閉じるように移動させても、第２の係止突起１９が第２のストッパー１３に当接して、スライドドア１ｃ１の開口部２(図１２参照)を閉じる方向の移動が阻止される。
また、スライドドア１ｃ１で開口部２(図１２参照)を閉じる方向は、操作レバー８の他方の回動方向（図１２、スライドドア１ｃ１の内側Ｉから見て時計回りの方向）であり、操作レバー８の他方の回動方向の回動により第２のストッパー１９と第２の係止突起１３との係止状態が解除され(図１２参照)、解除後、スライドドア１ｃ１の開口部２(図１２参照)を閉じる方向の移動が許容される。
該許容後、スライドドア１ｃ１を開口部２(図１２参照)が閉じるように移動させて、第１の係止突起１４が第１のストッパー１２に当接し、第１の付勢部材１６に抗して第１の係止突起１４が移動して(図１３参照)、スライドドア１ｃ１の開口部２(図１２参照)を閉じる方向の移動が許容され、スライドドア１ｃ１が開口部２(図１２参照)を閉じるように移動させて第１の係止突起１４が第１のストッパー１２に非当接すると、第１の付勢部材１６により第１の係止突起１４が移動し(図１４参照)、該移動の後、スライドドア１ｃ１が開口部２(図１２参照)を開けるように移動させても、第１の係止突起１４が第１のストッパー１２に当接して、スライドドア１ｃ１の開口部２(図１２参照)を開ける方向の移動が阻止される。 That is, the direction in which the opening 2 (see FIG. 12) is opened by the slide door 1c1 is one of the rotation directions of the operation lever 8 (the counterclockwise direction as viewed from the inside I of the slide door 1c1 in FIG. 9). The locking state of the first stopper 12 and the first locking protrusion 14 is released by turning the operating lever 8 in one turning direction, and after releasing, the opening 2 of the slide door 1c1 (see FIG. 12). The movement in the direction of opening is allowed (see FIGS. 8 and 9).
After the allowance, the sliding door 1c1 is moved so that the opening 2 (see FIG. 12) is opened, and the second locking projection 19 comes into contact with the second stopper 13 and resists the second urging member 21. Then, the second locking projection 19 is moved (see FIG. 10), and the movement in the direction of opening the opening 2 (see FIG. 12) of the slide door 1c1 is allowed, and the slide door 1c1 is opened in the opening 2 (FIG. 12). When the second locking projection 19 is not in contact with the second stopper 13 by moving the second locking projection 19 so as to open (see FIG. 11). After the movement, even if the slide door 1c1 is moved so as to close the opening 2 (see FIG. 12), the second locking projection 19 comes into contact with the second stopper 13 and the slide door 1c1 Movement in the direction of closing the opening 2 (see FIG. 12) is prevented.
The direction in which the opening 2 (see FIG. 12) is closed by the slide door 1c1 is the other rotation direction of the operation lever 8 (the clockwise direction as viewed from the inside I of the slide door 1c1 in FIG. 12). The latching state of the second stopper 19 and the second latching protrusion 13 is released by turning the lever 8 in the other pivoting direction (see FIG. 12). After the release, the opening 2 of the slide door 1c1 ( Movement in the closing direction is permitted.
After the allowance, the sliding door 1c1 is moved so that the opening 2 (see FIG. 12) is closed, and the first locking projection 14 comes into contact with the first stopper 12 and resists the first biasing member 16. Then, the first locking projection 14 is moved (see FIG. 13), the movement in the direction of closing the opening 2 (see FIG. 12) of the slide door 1c1 is allowed, and the slide door 1c1 is opened in the opening 2 (FIG. 12). When the first locking projection 14 is not in contact with the first stopper 12 by moving the first locking projection 14 so as to be closed, the first biasing member 16 moves the first locking projection 14 (see FIG. 14). After the movement, even if the slide door 1c1 is moved so as to open the opening 2 (see FIG. 12), the first locking projection 14 comes into contact with the first stopper 12 and the slide door 1c1 Movement in the direction of opening the opening 2 (see FIG. 12) is prevented.

従って、上述した運搬車１００によれば、一つの操作レバー８を操作することにより、第１の係止突起１４を第１のストッパー１２に係止させてスライドドア１ｃ１の閉状態を維持し、また、第２の係止突起１９を第２のストッパー１３に係止させてスライドドア１ｃ１の開状態を維持するため、特に、運搬車１００が坂道で停車し、作業する際、スライドドア１ｃ１が不用意に、開いたり、閉じたりすることを防止することができ、作業性を向上させることができ、しかも、第１の係止突起１４と第１のストッパー１２との係止状態の解除から、車体の開口部２(図１２参照)を開ける一連の動作は、車体の開口部２(図１２参照)を開ける方向、つまり、操作レバー８の一方の回動方向であり、第２の係止突起１９と第２のストッパー１３との係止状態の解除から、車体の開口部２(図１２参照)を閉じる一連の動作は、車体の開口部２(図１２参照)を閉じる方向、つまり、操作レバー８の他方の回動方向であるため、操作性も良い。     Therefore, according to the transport vehicle 100 described above, by operating one operation lever 8, the first locking protrusion 14 is locked to the first stopper 12 to maintain the closed state of the slide door 1c1.

When the operation lever 8 is rotated in the other rotation direction (FIG. 17, clockwise direction when viewed from the inside I of the slide door 1c1), the second rotation body 11 is rotated by the protrusion 83. ing.

従って、図１７に示すように、第１のストッパー１２に第１の係止突起１４が係止して(図１７の破線で示す第１の係止突起１４参照)、スライドドア１ｃ１で車体の開口部を閉めた状態を保持する。
第１のストッパー１２と第１の係止突起１４との係止状態は、操作レバー８の一方の回動方向（図１７、スライドドア１ｃ１の内側Ｉから見て反時計回りの方向）の回動により、第１の回動体１０、第１の連結体１８を介して第１の係止突起１４の下方への移動により解除される。
そして、操作レバー８の一方の回動方向に力を作用させると、スライドドア１ｃ１が図１７に示す方向に移動する。スライドドア１ｃ１が移動すると、第２の係止突起１９の先端は、スライドドア１ｃ１による開口部を開ける移動方向に対して、上り勾配１９ｂに形成されているため、上り勾配１９ｂに第２のストッパー１３が当接し、第２の付勢部材２１に抗して第２の係止突起１９が上方へ移動し、第２のストッパー１３を乗り越える。乗り越えた後は、図１７に破線で示すように、第２の付勢部材２１により第２の係止突起１９が下方へ移動し、第２のストッパー１３に第２の係止突起１９が係止して、スライドドア１ｃ１で車体の開口部を開けた状態を保持することとなる。
次に、スライドドア１ｃ１で車体の開口部を開けた状態から閉じる状態にするには、操作レバー８の他方の回動方向（図１７、スライドドア１ｃ１の内側Ｉから見て時計回りの方向）の回動により、第２の回動体１１、第２の連結体２３を介して、第２の係止突起１９の上方への移動により解除される。
そして、操作レバー８の他方の回動方向に力を作用させると、スライドドア１ｃ１が図１７に示す方向に移動する。スライドドア１ｃ１が移動すると、第１の係止突起１４の先端は、スライドドア１ｃ１による開口部を開ける移動方向に対して、下がり勾配１４ｂに形成されているため、下がり勾配１４ｂに第１のストッパー１２が当接し、第１の付勢部材１６に抗して第１の係止突起１４が下方へ移動し、第１のストッパー１２を乗り越える。乗り越えた後は、図１７に破線で示すように、第１の付勢部材１６により第１の係止突起１４が上方へ移動し、第１のストッパー１２に第１の係止突起１４が係止して、スライドドア１ｃ１で車体の開口部を閉じた状態を保持することとなる。 Accordingly, as shown in FIG. 17, the first locking projection 14 is locked to the first stopper 12 (see the first locking projection 14 indicated by the broken line in FIG. 17), and the vehicle body is moved by the slide door 1c1. Keep the opening closed.
The locking state between the first stopper 12 and the first locking protrusion 14 is the rotation of one rotation direction of the operation lever 8 (the counterclockwise direction when viewed from the inside I of the slide door 1c1 in FIG. 17). The movement is released by the downward movement of the first locking projection 14 via the first rotating body 10 and the first connecting body 18.
When a force is applied in one rotation direction of the operation lever 8, the slide door 1c1 moves in the direction shown in FIG. When the slide door 1c1 moves, the tip of the second locking projection 19 is formed in the upward gradient 19b with respect to the moving direction for opening the opening by the slide door 1c1, and therefore the second stopper is set in the upward gradient 19b. 13 abuts, the second locking projection 19 moves upward against the second urging member 21, and gets over the second stopper 13. After getting over, as shown by a broken line in FIG. 17, the second locking projection 19 is moved downward by the second urging member 21, and the second locking projection 19 is engaged with the second stopper 13. It stops, and the state which opened the opening part of the vehicle body with the slide door 1c1 will be hold | maintained.
Next, in order to change the opening of the vehicle body from the open state to the closed state by the slide door 1c1, the other rotation direction of the operation lever 8 (the clockwise direction as viewed from the inside I of the slide door 1c1). Is released by the upward movement of the second locking projection 19 via the second rotating body 11 and the second connecting body 23.
When a force is applied in the other rotation direction of the operation lever 8, the slide door 1c1 moves in the direction shown in FIG. When the sliding door 1c1 moves, the tip of the first locking projection 14 is formed in a downward gradient 14b with respect to the moving direction for opening the opening by the sliding door 1c1, and therefore the first stopper is applied to the downward gradient 14b. 12 abuts against the first urging member 16, and the first locking projection 14 moves downward to get over the first stopper 12. After getting over, as shown by a broken line in FIG. 17, the first urging member 16 moves the first locking projection 14 upward, and the first locking projection 14 is engaged with the first stopper 12. It stops, and the state which closed the opening part of the vehicle body with the slide door 1c1 will be hold | maintained.

つまり、スライドドア１ｃ１で開口部２(図１２参照)を開ける方向は、操作レバー８の一方の回動方向（図１７、スライドドア１ｃ１の内側Ｉから見て反時計回りの方向）であり、操作レバー８の一方の回動方向の回動により第１のストッパー１２と第１の係止突起１４との係止状態が解除され（図１７の第１の係止突起１４が破線の位置から実線の位置へ移動)、解除後、スライドドア１ｃ１の開口部２(図１２参照)を開ける方向の移動が許容される。
該許容後、スライドドア１ｃ１を開口部２(図１２参照)が開くように移動させて、第２の係止突起１９が第２のストッパー１３に当接し、第２の付勢部材２１に抗して第２の係止突起１９が移動して、スライドドア１ｃ１の開口部２(図１２参照)を開ける方向の移動が許容され、スライドドア１ｃ１が開口部２(図１２参照)を開くように移動させて第２の係止突起１９が第２のストッパー１３に非当接すると、第２の付勢部材２１により第２の係止突起１９が移動し（図１７の第２の係止突起１９が実線の位置から破線の位置へ移動)、該移動の後、スライドドア１ｃ１が開口部２(図１２参照)を閉じるように移動させても、第２の係止突起１９が第２のストッパー１３に当接して、スライドドア１ｃ１の開口部２(図１２参照)を閉じる方向の移動が阻止される。
また、スライドドア１ｃ１で開口部２(図１２参照)を閉じる方向は、操作レバー８の他方の回動方向（図１７、スライドドア１ｃ１の内側Ｉから見て時計回りの方向）であり、操作レバー８の他方の回動方向の回動により第２のストッパー１３と第２の係止突起１９との係止状態が解除され、解除後、スライドドア１ｃ１の開口部２(図１２参照)を閉じる方向の移動が許容される（図１７の第２の係止突起１９が破線の位置から実線の位置へ移動)。
該許容後、スライドドア１ｃ１を開口部２(図１２参照)が閉じるように移動させて、第１の係止突起１４が第１のストッパー１２に当接し、第１の付勢部材１６に抗して第１の係止突起１４が移動して、スライドドア１ｃ１の開口部２(図１２参照)を閉じる方向の移動が許容され、スライドドア１ｃ１が開口部２(図１２参照)を閉じるように移動させて第１の係止突起１４が第１のストッパー１２に非当接すると、第１の付勢部材１６により第１の係止突起１４が移動し（図１７の第１の係止突起１４が実線の位置から破線の位置へ移動)、該移動の後、スライドドア１ｃ１が開口部２(図１２参照)を開けるように移動させても、第１の係止突起１４が第１のストッパー１２に当接して、スライドドア１ｃ１の開口部２(図１２参照)を開ける方向の移動が阻止される。 That is, the direction in which the opening 2 (see FIG. 12) is opened by the slide door 1c1 is one of the rotation directions of the operation lever 8 (the counterclockwise direction when viewed from the inside I of the slide door 1c1). The locking state of the first stopper 12 and the first locking projection 14 is released by the rotation of the operation lever 8 in one rotation direction (the first locking projection 14 in FIG. After movement, the movement in the direction of opening the opening 2 (see FIG. 12) of the slide door 1c1 is allowed.
After the allowance, the sliding door 1c1 is moved so that the opening 2 (see FIG. 12) is opened, and the second locking projection 19 comes into contact with the second stopper 13 and resists the second urging member 21. Then, the second locking projection 19 moves to allow movement in the direction of opening the opening 2 (see FIG. 12) of the slide door 1c1, and the slide door 1c1 opens the opening 2 (see FIG. 12). When the second locking projection 19 is not in contact with the second stopper 13 by moving the second locking projection 19, the second locking projection 19 is moved by the second biasing member 21 (the second locking projection in FIG. 17). The protrusion 19 moves from the position of the solid line to the position of the broken line). After the movement, even if the slide door 1c1 is moved so as to close the opening 2 (see FIG. 12), the second locking protrusion 19 is In the direction of closing the opening 2 (see FIG. 12) of the sliding door 1c1. There is prevented.
The direction in which the opening 2 (see FIG. 12) is closed by the slide door 1c1 is the other rotation direction of the operation lever 8 (FIG. 17, the clockwise direction when viewed from the inside I of the slide door 1c1). By the rotation of the lever 8 in the other rotation direction, the locked state between the second stopper 13 and the second locking projection 19 is released, and after the release, the opening 2 (see FIG. 12) of the slide door 1c1 is opened. Movement in the closing direction is allowed (the second locking projection 19 in FIG. 17 moves from the position of the broken line to the position of the solid line).
After the allowance, the sliding door 1c1 is moved so that the opening 2 (see FIG. 12) is closed, and the first locking projection 14 comes into contact with the first stopper 12 and resists the first biasing member 16. As a result, the first locking projection 14 moves to allow movement in the direction of closing the opening 2 (see FIG. 12) of the slide door 1c1, and the slide door 1c1 closes the opening 2 (see FIG. 12). When the first locking protrusion 14 is not in contact with the first stopper 12 by moving the first locking protrusion 14, the first locking protrusion 14 is moved by the first urging member 16 (the first locking protrusion in FIG. 17). The protrusion 14 moves from the position of the solid line to the position of the broken line). After the movement, even if the slide door 1c1 is moved so as to open the opening 2 (see FIG. 12), the first locking protrusion 14 is Direction in which the opening 2 (see FIG. 12) of the slide door 1c1 is opened in contact with the stopper 12 Movement is prevented.
