〔作用及び効果〕
プラグ先端部を、ガス流入路の一部を形成する第１筒部と、ガス流入路の一部を形成する第２筒部とを、筒軸芯に沿って一定範囲で互いに遠近方向に往復移動自在、かつ、気密に接続して構成し、周溝部を囲んで互いに対向する一対の環状溝側面のうちの一方の溝側面を第１筒部に形成するとともに、他方の溝側面を第２筒部に形成してあるので、第１筒部と第２筒部とを互いに遠近方向に往復移動させると、一対の環状溝側面どうしも互いに遠近方向に往復移動する。
そして、ガス流入路を開閉自在な弁機構と、一対の環状溝側面の間に球体が入り込むように第１筒部と第２筒部とが互いに離間移動する動作に連係して弁機構を開弁させ、第１筒部と第２筒部とが互いに近接移動する動作に連係して弁機構を閉弁させる連係機構とをプラグ先端部に設けてあるので、第１筒部と第２筒部とが互いに離間している状態、つまり、弁機構が開弁している状態で、上記ソケットを使用せずに、誤って、ガスホースの内側にプラグ先端部を無理やり直に押し込むと、その押し込み動作に伴って、ガスホースとの摩擦力で第１筒部又は第２筒部がガスホースと共に押し込み方向に連れ動きして、第１筒部と第２筒部とが互いに近接移動し、その近接移動する動作に連係して弁機構が閉弁して、ガス供給先をガス供給元に連通接続できない状態に切り換わる。
また、ソケット先端部をプラグ先端部に外嵌する操作で、ソケット先端部と周溝部とに亘って球体を係合させて、ソケット先端部とプラグ先端部との接続解除を阻止する状態にボールデテント機構を切り換えてある状態では、一対の環状溝側面で囲まれた周溝部に球体が入り込むように第１筒部と第２筒部とが互いに離間しており、周溝部に球体が入り込むように第１筒部と第２筒部とが互いに離間移動する動作に連係して弁機構が開弁するので、ガス供給先をガス供給元に連通接続できる状態に切り換わっている。
尚、第１筒部と第２筒部とが互いに近接している状態、つまり、弁機構が閉弁されている状態で、ガスホースの内側にプラグ先端部を無理やり直に押し込むときは、第１筒部又は第２筒部が互いに近接する方向にガスホースで押圧されるので、第１筒部と第２筒部とが互いに離間移動することはなく、弁機構は閉弁状態に維持される。
従って、上記ソケットを使用せずに、誤って、ガスホースの内側にプラグ先端部を無理やり直に押し込んでも、ガス供給先をガス供給元に連通接続できない状態に切り換わる、又は、その状態に維持されるので、安全性を確保できる。 [Action and effect]
The plug tip part reciprocates in the perspective direction within a certain range along the cylinder axis between the first cylinder part that forms part of the gas inflow path and the second cylinder part that forms part of the gas inflow path. One groove side surface of the pair of annular groove side surfaces, which are configured to be movable and connected in an airtight manner and surround the circumferential groove portion, is formed in the first tube portion, and the other groove side surface is defined as the second groove side surface. Since it is formed in the cylindrical portion, when the first cylindrical portion and the second cylindrical portion are reciprocated in the perspective direction, the pair of annular groove side surfaces are reciprocated in the perspective direction.
Then, the valve mechanism is opened in conjunction with a valve mechanism that can freely open and close the gas inflow passage and an operation in which the first cylinder portion and the second cylinder portion move away from each other so that the sphere enters between the side surfaces of the pair of annular grooves. Since the plug tip portion is provided with a linkage mechanism for closing the valve mechanism in conjunction with the movement of the first cylinder portion and the second cylinder portion to move close to each other, the first cylinder portion and the second cylinder If the plug tip is forcibly pushed into the inside of the gas hose by mistake without using the socket in the state where the parts are separated from each other, that is, the valve mechanism is open, Along with the operation, the first cylinder part or the second cylinder part moves along with the gas hose in the pushing direction by the frictional force with the gas hose, and the first cylinder part and the second cylinder part move close to each other, and the proximity movement thereof. The valve mechanism closes in conjunction with the operation, and the gas supply destination becomes the gas supply source. It switched to a state that can not be through connection.
Further, by fitting the socket tip part to the plug tip part, the ball is engaged with the sphere over the socket tip part and the circumferential groove part to prevent the socket tip part and the plug tip part from being disconnected. In a state where the detent mechanism is switched, the first cylindrical portion and the second cylindrical portion are separated from each other so that the spherical body enters the circumferential groove portion surrounded by the pair of annular groove side surfaces, and the spherical body enters the circumferential groove portion. Since the valve mechanism is opened in conjunction with the movement of the first cylinder part and the second cylinder part away from each other, the gas supply destination is switched to a state where it can be connected to the gas supply source.
When the plug tip is forcibly pushed into the inside of the gas hose with the first cylinder and the second cylinder close to each other, that is, with the valve mechanism closed, the first cylinder Since the tube portion or the second tube portion is pressed by the gas hose in the direction in which they are close to each other, the first tube portion and the second tube portion do not move away from each other, and the valve mechanism is maintained in the valve-closed state.
Therefore, even if the plug tip is forcibly pushed into the inside of the gas hose by mistake without using the socket, the gas supply destination is switched to a state where it cannot be connected to the gas supply source or maintained in that state. Therefore, safety can be ensured.

本発明の第２特徴構成は、前記第１筒部と前記第２筒部とを互いに離間移動する方向に弾性付勢する第１付勢部材を前記プラグ先端部に設けてある点にある。   According to a second characteristic configuration of the present invention, a first urging member that elastically urges the first cylinder part and the second cylinder part to move away from each other is provided at the plug tip part.

〔作用及び効果〕
第１筒部と第２筒部とを互いに離間移動する方向に弾性付勢する第１付勢部材をプラグ先端部に設けてあるので、ソケット先端部をプラグ先端部に外嵌していない非接続状態において、第１筒部と第２筒部とを第１付勢部材の付勢力で互いに離間移動させて、その離間移動する動作に連係して弁機構を開弁させておくことができる。
そして、弁機構が開弁している状態で、上記ソケットを使用せずに、誤って、ガスホースの内側にプラグ先端部を無理やり直に押し込むと、その押し込み動作に伴って、第１筒部又は第２筒部を、第１付勢部材の付勢力に抗して、ガスホースと共に押し込み方向に連れ動きさせて、第１筒部と第２筒部とを互いに近接移動させ、その近接移動する動作に連係して弁機構を閉弁させて、ガス供給先をガス供給元に連通接続できない状態に切り換えることができる。
また、誤ってプラグ先端部を押し込んだガスホースをそのプラグ先端部から抜き出すと、第１筒部と第２筒部とを第１付勢部材の付勢力で互いに離間移動させて、弁機構を開弁状態に復帰させることができる。
そして、ソケット先端部をプラグ先端部に外嵌する操作で、ソケット先端部と周溝部とに亘って球体を係合させて、ソケット先端部とプラグ先端部との接続解除を阻止する状態にボールデテント機構を切り換えた状態では、第１筒部と第２筒部とを第１付勢部材の付勢力で互いに離間移動させて、弁機構を確実に開弁させておくことができる。
従って、ソケット先端部をプラグ先端部に外嵌した状態で、ガス供給先をガス供給元に連通接続できる状態に確実に切り換えることができるようにしながら、誤ってガスホースにプラグ先端部を押し込んだときには、ガス供給先をガス供給元に連通接続できない状態に切り換えることができる。 [Action and effect]
Since the first urging member for elastically urging the first cylinder part and the second cylinder part away from each other is provided at the plug tip part, the socket tip part is not externally fitted to the plug tip part. In the connected state, the first cylinder part and the second cylinder part can be moved away from each other by the urging force of the first urging member, and the valve mechanism can be opened in conjunction with the separated movement. .
When the plug tip is forcibly pushed into the gas hose by mistake without using the socket while the valve mechanism is open, the first cylinder or The second cylinder part is moved in the pushing direction together with the gas hose against the urging force of the first urging member, and the first cylinder part and the second cylinder part are moved in proximity to each other and moved in proximity to each other. The gas supply destination can be switched to a state in which the gas supply destination cannot be connected to the gas supply source by closing the valve mechanism.
If the gas hose that has accidentally pushed the plug tip is removed from the plug tip, the first cylinder and the second cylinder are moved away from each other by the biasing force of the first biasing member to open the valve mechanism. The valve state can be restored.
Then, by fitting the socket tip part to the plug tip part, the ball is engaged with the sphere over the socket tip part and the circumferential groove part to prevent the socket tip part and the plug tip part from being disconnected. In the state where the detent mechanism is switched, the valve mechanism can be reliably opened by moving the first cylinder portion and the second cylinder portion away from each other by the urging force of the first urging member.
Therefore, when the plug tip is accidentally pushed into the gas hose, while the socket tip is fitted over the plug tip, the gas supply destination can be switched to a state where it can be connected to the gas supply source. The gas supply destination can be switched to a state in which the gas supply destination cannot be connected to the gas supply source.

本発明の第３特徴構成は、前記第１筒部と前記第２筒部とを互いに近接移動する方向に弾性付勢する第２付勢部材を前記プラグ先端部に設けてある点にある。   According to a third characteristic configuration of the present invention, a second urging member that elastically urges the first cylinder part and the second cylinder part toward each other is provided at the plug tip part.

〔作用及び効果〕
第１筒部と第２筒部とを互いに近接移動する方向に弾性付勢する第２付勢部材をプラグ先端部に設けてあるので、ソケット先端部をプラグ先端部に外嵌していない非接続状態において、第１筒部と第２筒部とを第２付勢部材の付勢力で互いに近接移動させて、その近接移動する動作に連係して弁機構を閉弁させておくことができ、誤ってプラグ先端部をガスホースに押し込んだ状態において、弁機構を閉弁状態に確実に維持できる。
そして、ソケット先端部をプラグ先端部に外嵌する操作で、ソケット先端部と周溝部とに亘って球体を係合させて、ソケット先端部とプラグ先端部との接続解除を阻止する状態にボールデテント機構を切り換える際に、互いに近接している一対の環状溝側面間に球体を押し込むに伴って、第１筒部と第２筒部とが第２付勢部材の付勢力に抗して互いに離間移動させることができるので、その離間移動する動作に連係して弁機構を開弁させて、ガス供給先をガス供給元に連通接続できる状態に切り換えることができる。
従って、誤ってガスホースにプラグ先端部を押し込んだ状態で、ガス供給先をガス供給元に連通接続できない状態に確実に維持できるようにしながら、ソケット先端部をプラグ先端部に外嵌する操作で、ガス供給先をガス供給元に連通接続できる状態に切り換えることができる。 [Action and effect]
Since the second urging member that elastically urges the first cylinder part and the second cylinder part toward each other is provided at the plug tip part, the socket tip part is not fitted on the plug tip part. In the connected state, the first cylinder part and the second cylinder part can be moved close to each other by the urging force of the second urging member, and the valve mechanism can be closed in conjunction with the movement of the proximity movement. When the plug tip is accidentally pushed into the gas hose, the valve mechanism can be reliably maintained in the closed state.
Then, by fitting the socket tip part to the plug tip part, the ball is engaged with the sphere over the socket tip part and the circumferential groove part to prevent the socket tip part and the plug tip part from being disconnected. When the detent mechanism is switched, as the sphere is pushed between the side surfaces of the pair of annular grooves that are close to each other, the first cylindrical portion and the second cylindrical portion are opposed to each other against the urging force of the second urging member. Since they can be moved away from each other, the valve mechanism can be opened in conjunction with the operation of moving away and the gas supply destination can be switched to a state where it can be connected to the gas supply source.
Therefore, in the state where the plug tip is accidentally pushed into the gas hose and the gas supply destination can be reliably maintained in a state where the gas supply destination cannot be connected to the gas supply source, the socket tip is externally fitted to the plug tip. The gas supply destination can be switched to a state in which the gas supply destination can be connected to the gas supply source.

本発明の第４特徴構成は、前記弁機構を構成するに、前記第１筒部又は第２筒部の一方の筒部に、弁体をその内周面に対して隙間を隔てて取り付けるとともに、他方の筒部に、前記弁体に対して筒軸芯方向に相対的に離間することによって開弁し、前記弁体に対して筒軸芯方向から相対的に押し付けることにより閉弁する環状の弁座を設けて構成してある点にある。   According to a fourth characteristic configuration of the present invention, in order to configure the valve mechanism, a valve body is attached to one of the first cylindrical portion or the second cylindrical portion with a gap from the inner peripheral surface thereof. The other cylinder portion is opened by being relatively separated from the valve body in the cylinder axis direction, and is closed by being pressed against the valve body from the cylinder axis direction. The valve seat is provided.

〔作用及び効果〕
一対の環状溝側面の間に球体が入り込むように第１筒部と第２筒部とが互いに離間移動するに伴って、弁体と弁座とを離間させて開弁でき、第１筒部と第２筒部とが互いに近接移動するに伴って、弁体を弁座に押し付けて閉弁できるので、連係機構の簡略化を図ることができる。 [Action and effect]
As the first cylindrical portion and the second cylindrical portion move away from each other so that the spherical body enters between the pair of annular groove side surfaces, the valve body and the valve seat can be separated to open the first cylindrical portion. Since the valve body can be pressed against the valve seat and closed as the second cylinder portion and the second cylinder portion move closer to each other, the linkage mechanism can be simplified.

前記ソケット先端部５の周壁１２の内面側に、圧縮スプリング７を介して、弁作動リング１３を筒軸芯Ｘ方向にスライド移動自在に内嵌するとともに、周壁１２の外面側に、圧縮スプリング１４を介して、操作用リング１５を筒軸芯Ｘ方向にスライド移動自在に外嵌し、周壁１２の先端部に形成した貫通孔１６に球体１１を収容して、その球体１１を弁作動リング１３と操作用リング１５との間に挟んである。 The ball detent mechanism C will be described.
A valve operating ring 13 is fitted on the inner surface side of the peripheral wall 12 of the socket tip 5 via a compression spring 7 so as to be slidable in the direction of the cylinder axis X, and a compression spring 14 is disposed on the outer surface side of the peripheral wall 12. The operating ring 15 is externally fitted so as to be slidable in the direction of the cylinder axis X, and the sphere 11 is accommodated in the through-hole 16 formed in the distal end portion of the peripheral wall 12. And the operation ring 15.

前記弁作動リング１３は、その後端に弁体９が一体に連設されており、非接続状態では、弁体９が、圧縮スプリング７の付勢力で、周壁１２の内周に環状に突設された弁座８に圧接されて、図１に示すように、ガス流出路４を遮断している。   The valve operating ring 13 has a valve body 9 integrally connected to the rear end thereof, and in a non-connected state, the valve body 9 projects annularly on the inner periphery of the peripheral wall 12 by the urging force of the compression spring 7. As shown in FIG. 1, the gas outflow passage 4 is blocked by being pressed against the valve seat 8.

そして、ソケット先端部５をプラグ先端部２に外嵌するに伴って、弁作動リング１３がプラグ先端部２で圧縮スプリング７の付勢力に抗して押し込まれ、非接続状態では圧縮スプリング１４の付勢力で操作用リング１５の段部１７を介して弁作動リング１３に向けて押圧されていた球体１１が、プラグ先端部３の周溝部１０に押し込まれて、ソケット先端部５と周溝部１０とに亘って係合し、ソケット先端部５とプラグ先端部２との接続解除を阻止する状態に切り換えられる。   Then, as the socket tip 5 is fitted onto the plug tip 2, the valve operating ring 13 is pushed against the urging force of the compression spring 7 at the plug tip 2, and the compression spring 14 of the compression spring 14 is not connected. The sphere 11 that has been pressed toward the valve operating ring 13 via the step portion 17 of the operation ring 15 by the urging force is pushed into the circumferential groove portion 10 of the plug tip portion 3, and the socket tip portion 5 and the circumferential groove portion 10. To the state where the connection between the socket tip 5 and the plug tip 2 is prevented from being released.

また、このときの弁作動リング１３の押し込みにより、弁作動リング１３の後端に一体に連設されている弁体９が、周壁１２の内周側に突設されている弁座８から離間して開弁し、ガス供給先がガス供給元に連通接続される。   Further, when the valve operating ring 13 is pushed at this time, the valve body 9 integrally connected to the rear end of the valve operating ring 13 is separated from the valve seat 8 protruding on the inner peripheral side of the peripheral wall 12. Then, the valve is opened, and the gas supply destination is connected to the gas supply source.

次に、プラグＡからソケットＢを外すときには、操作用リング１５を圧縮スプリング１４の付勢力に抗してスライド操作することにより、周溝部１０に入り込んでいた球体１１が操作用リング１５の内周面に形成してある段部１７に入り込める状態になり、この状態でソケットＢをプラグＡから引き抜く操作に伴って、球体１１が溝側面１０ａに押圧されて段部１７に入り込んで、ソケットＢがプラグＡから外れ、同時に、圧縮スプリング７の付勢力で弁体９が弁作動リング１３と共に復帰移動して、球体１１が弁作動リング１３と操作用リング１５との間に挟み込まれると共に、弁体９が弁座８に接当してガス流出路４が遮断される。   Next, when the socket B is removed from the plug A, the operating ring 15 is slid against the urging force of the compression spring 14, so that the sphere 11 that has entered the circumferential groove portion 10 is moved to the inner periphery of the operating ring 15. When the socket B is pulled out from the plug A in this state, the sphere 11 is pressed by the groove side surface 10a and enters the step 17, so that the socket B is inserted into the step 17 formed on the surface. At the same time, the valve body 9 is returned and moved together with the valve operating ring 13 by the urging force of the compression spring 7 so that the spherical body 11 is sandwiched between the valve operating ring 13 and the operating ring 15 and the valve body. 9 contacts the valve seat 8 and the gas outflow path 4 is shut off.

前記プラグＡは、プラグ先端部２を、ガス流入路１の一部を形成するプラグ先端側の第１筒部１８と、ガス流入路２の残りの部分を形成するプラグ基部３側の第２筒部１９とを、第１筒部１８に連接した筒軸２０を第２筒部１９の先端側に形成した軸孔２１に嵌入するとともに、筒軸２０の先端側に抜け止めリング２２を装着して、筒軸芯Ｘに沿って一定範囲で互いに遠近方向に往復移動自在、かつ、軸孔２１に装着したシールリング２３で気密に接続して構成してある。   In the plug A, the plug tip portion 2 includes a first tube portion 18 on the plug tip side that forms part of the gas inflow passage 1 and a second portion on the plug base portion 3 side that forms the remaining portion of the gas inflow passage 2. A cylindrical shaft 20 connected to the first cylindrical portion 18 is fitted into a cylindrical hole 21 formed on the distal end side of the second cylindrical portion 19, and a retaining ring 22 is attached to the distal end side of the cylindrical shaft 20. Then, they are configured to be reciprocally movable toward and away from each other within a certain range along the cylinder axis X, and are hermetically connected by a seal ring 23 attached to the shaft hole 21.

前記一対の溝側面１０ａ，１０ｂのうちの一方の溝側面１０ａを第１筒部１８に形成し、他方の溝側面１０ｂを第２筒部１９に形成し、第１筒部１８と第２筒部１９とを互いに離間移動する方向に弾性付勢する第１付勢部材２４としての圧縮コイルスプリングを筒軸２０の外周側に遊嵌してある。   One groove side surface 10a of the pair of groove side surfaces 10a and 10b is formed in the first tube portion 18, and the other groove side surface 10b is formed in the second tube portion 19, and the first tube portion 18 and the second tube are formed. A compression coil spring as a first biasing member 24 that elastically biases the portion 19 in the direction of moving away from each other is loosely fitted to the outer peripheral side of the cylindrical shaft 20.

そして、ガス流入路１を開閉自在な弁機構Ｄと、一対の溝側面１０ａ，１０ｂの間に球体１１が入り込むように第１筒部１８と第２筒部１９とが互いに離間移動する動作に連係して弁機構Ｄを開弁させ、第１筒部１８と第２筒部１９とが互いに近接移動する動作に連係して弁機構Ｄを閉弁させる連係機構Ｅとを設けてある。   The first cylinder 18 and the second cylinder 19 move away from each other so that the spherical body 11 enters between the valve mechanism D that can freely open and close the gas inflow passage 1 and the pair of groove side surfaces 10a and 10b. There is provided a linkage mechanism E that opens the valve mechanism D in linkage and closes the valve mechanism D in linkage with an operation in which the first cylinder portion 18 and the second cylinder portion 19 move close to each other.

前記弁機構Ｄは、図６にも示すように、第２筒部１９の内側に、先端側を第１筒部１８側に向けた円錐形の弁体２５を、その筒部内周面に対して隙間Ｓを隔てて同芯状に固定するとともに、第１筒部１８に、弁体２５に対して筒軸芯方向に離間させることによって開弁し、弁体２５に対して筒軸芯方向から押し付けることにより閉弁する円環状の弁座２６を設けて構成してある。   As shown in FIG. 6, the valve mechanism D includes a conical valve body 25 with the tip side facing the first cylinder portion 18 on the inner side of the second cylinder portion 19 with respect to the inner peripheral surface of the cylinder portion. The first cylinder portion 18 is opened by being spaced apart from the valve body 25 in the cylinder axis direction, and is fixed in the cylinder axis direction with respect to the valve body 25. An annular valve seat 26 that is closed by being pressed is provided.

そして、弁座２６を第１筒部１８に連接してある筒軸２０の端縁で形成して、一対の溝側面１０ａ，１０ｂの間に球体１１が入り込むように、圧縮コイルスプリング２４の付勢力で第１筒部１８と第２筒部１９とが互いに離間移動する動作で、弁座２６を弁体２５から離間させて弁機構Ｄを開弁し、誤って、ガスホース２８にプラグ先端部２を無理やり押し込んだときに、ガスホース２８の内面との摩擦力で第１筒部１８が押し込み方向に連れ動きして、圧縮コイルスプリング２４の付勢力に抗して第１筒部１８と第２筒部１９とが互いに近接移動する動作で、図５に示すように、弁座２６を弁体２５に対して押し付けて弁機構Ｄを開弁する連係機構Ｅを構成してある。   Then, the valve seat 26 is formed by the end edge of the cylindrical shaft 20 connected to the first cylindrical portion 18, and the compression coil spring 24 is attached so that the sphere 11 enters between the pair of groove side surfaces 10a, 10b. By the operation in which the first cylinder portion 18 and the second cylinder portion 19 move away from each other by force, the valve mechanism D is opened by separating the valve seat 26 from the valve body 25, and the plug tip portion is accidentally connected to the gas hose 28. When the 2 is forcibly pushed in, the first cylinder portion 18 moves in the pushing direction by the frictional force with the inner surface of the gas hose 28, and resists the urging force of the compression coil spring 24 and the second cylinder portion 18 and the second cylinder portion 18. As shown in FIG. 5, the linkage mechanism E is configured to open the valve mechanism D by pressing the valve seat 26 against the valve body 25 by an operation in which the cylinder portion 19 moves close to each other.

つまり、ソケットＢをプラグ先端部２に外嵌するべく、第１筒部１８をソケット先端部５の内側に押し込んで弁作動リング１３を押圧するに伴って、図３に示すように、その押圧反力で第１筒部１８が圧縮コイルスプリング２４の付勢力に抗して第２筒部１９側に近接移動して、一旦、一対の溝側面１０ａ，１０ｂどうしが近接し、更に第１筒部１８をソケット先端部５に押し込んで、図４に示すように、球体１１が一対の溝側面１０ａ，１０ｂ間に対応する位置に移動するに伴って、図２に示したように、球体１１が一対の溝側面１０ａ，１０ｂ間の周溝部１０に入り込むように、第１筒部１８と第２筒部１９とが圧縮コイルスプリング２４の付勢力で互いに離間移動して、弁機構Ｄが開弁する。   That is, as shown in FIG. 3, as the first cylinder 18 is pushed into the socket tip 5 and the valve operating ring 13 is pressed in order to fit the socket B to the plug tip 2, as shown in FIG. The first cylinder part 18 moves closer to the second cylinder part 19 side against the urging force of the compression coil spring 24 by the reaction force, and the pair of groove side surfaces 10a and 10b once approach each other, and further the first cylinder. The portion 18 is pushed into the socket tip 5 and, as shown in FIG. 4, as the sphere 11 moves to a corresponding position between the pair of groove side surfaces 10a, 10b, as shown in FIG. The first cylinder 18 and the second cylinder 19 are moved away from each other by the urging force of the compression coil spring 24 so that the valve mechanism D is opened so that the first cylinder 18 and the second cylinder 19 are moved into the circumferential groove 10 between the pair of groove side surfaces 10a and 10b. I speak.

〔第２実施形態〕
図示しないが、第１筒部１８と第２筒部１９とを互いに近接移動する方向に弾性付勢する第２付勢部材としての引っ張りコイルスプリングを筒軸２０の外周側に遊嵌して、ソケットＢをプラグ先端部２に外嵌していない非接続状態でも、誤って、ガスホース２８にプラグ先端部２を無理やり押し込んだときでも、引っ張りコイルスプリングの付勢力で弁座２６を弁体２５に押し付けて弁機構Ｄを閉弁状態に維持できるように構成しても良い。 [Second Embodiment]
Although not shown in the drawings, a tension coil spring as a second biasing member that elastically biases the first cylindrical portion 18 and the second cylindrical portion 19 in the direction in which they move close to each other is loosely fitted to the outer peripheral side of the cylindrical shaft 20, Even in a disconnected state where the socket B is not externally fitted to the plug tip 2, even when the plug tip 2 is forcibly pushed into the gas hose 28 by mistake, the valve seat 26 is attached to the valve body 25 by the urging force of the tension coil spring. You may comprise so that it can press and can maintain the valve mechanism D in a valve closing state.

尚、本実施形態の場合、ソケットＢをプラグ先端部２に外嵌するに伴って、一対の溝側面１０ａ，１０ｂ間の周溝部１０に球体１１が入り込むように、引っ張りコイルスプリングの付勢力に抗して第１筒部１８と第２筒部１９とが互いに離間移動する動作で、弁座２６を弁体２５から離間させて弁機構Ｄを開弁させる連係機構Ｅを構成する。
その他の構成は第１実施形態と同様である。 In the case of this embodiment, as the socket B is externally fitted to the plug tip 2, the biasing force of the tension coil spring is applied so that the sphere 11 enters the circumferential groove 10 between the pair of groove side surfaces 10a, 10b. Accordingly, the first cylinder portion 18 and the second cylinder portion 19 move away from each other to constitute a linkage mechanism E that opens the valve mechanism D by separating the valve seat 26 from the valve body 25.
Other configurations are the same as those of the first embodiment.
