第一元件1 0在其上端，形成上側平坦面1 0 A，從第一元 件1 0的内側，向著上側平坦面1 0 A，開口形成第一流路1 Ο B。 另外，在第一流路1 Ο B的側面的上側平坦面1 Ο A處，穿 透設置内螺紋孔1 0 C，更具體地說是，多個内螺紋孔1 0 C 穿透設置於包含上側平坦面1 Ο A的突邊部1 0 D處。 元件符號2 0是作為被連接的另一個元件的第二元件， 同樣由鋁等金屬材料製成。 在第二元件2 0的下端，形成下側平坦面2 0 A，從第二元 件2 0的内側，向著下側平坦面2 0 A，開口形成第二流路2 Ο B。 又，在第二流路2 Ο B的側面的下側平坦面2 Ο A上，形成 與内螺紋孔1 0 C對應的通孔2 0 C，多個該通孔2 0 C穿透設 置在包含下側平坦面2 Ο A的突邊部2 0 D處。 另外，圍繞開口於下側平坦面2 Ο A的第二流路2 Ο B，形 6 312/發明說明書(補件)/92-10/9212063 7 1231741 成0形環槽2 Ο E，0形環2 1放置在該0形環槽内。 第一元件1 0和第二元件2 0係依如下方式連接。 即：將第二元件2 0的下側平坦面2 0 Α頂接配置在第一 元件1 0的上側平坦面1 0 A上，在這個狀態下，通過通孔 2 0 C，向著内螺紋孔1 0 C將螺釘B擰緊。 如此一來，由於第一元件1 0和第二元件2 0分別具有平 坦面1 0 A、2 0 A並加以螺合固緊，因此，這時開口於上側平 坦面1 0 A的第一流路1 0 B和開口於下側平坦面2 0 A的第二 流路2 0 B，通過上述頂接面而將流路連接。 在這種連接狀態下，通過將配置在第二元件2 0的0形 環槽2 0 E内的0形環2 1抵壓配置在第一元件1 0的上側平 坦面1 0 A上，抑制從第一流路1 0 B、第二流路2 0 B經上側 平坦面1 0 A和下側平坦面2 0 A的頂接面而向外洩漏的上述 流路内流體的洩漏。 【發明内容】 (發明所欲解決之問題） 由於在這種二元件之安裝裝置中，強烈希望降低製造成 本和減輕裝置的重量，因此，第一，希望共同使用現有的 元件。 第二，為了降低材料費和減輕重量，可用合成樹脂材料 製造元件。 即：以共用化為目標，共用第二元件2 0。以及第一元件 1 0用合成樹脂材料製成。 這相當於在圖4的狀態下，用合成樹脂材料製造第一元 312/發明說明書(補件)/92-10/92120637 1231741 件1 0。 即··由於用金屬材料製成的第二元件2 0係藉由螺釘Β， 與由合成樹脂材料製成的第一元件1 0固接，由此，隨著時 間的推移，螺釘Β的連接緊固力降低（這是由於合成樹脂 材料的耐蠕變性低的緣故），第一元件1 0的上側平坦面1 0 A 和第二元件2 0的下側平坦面2 0 A的面間壓力降低，使得由 0形環21產生的密封功能降低，因此，第一流路1 0 B、第 二流路2 Ο B内的流體，將產生從上述上側平坦面和下側平 坦面20A的頂接面向外洩漏的不良狀況。 本發明是考慮到二元件之安裝裝置的上述問題而提出 的，其目的是要提供一種上述裝置，將以往使用的金屬材 料製第二元件和合成樹脂材料製第一元件在利用其各自的 平坦面接續流路並予以固緊，以此可降低製造成本及減輕 重量。 (解決問題之手段） 為了達到.上述目的，本發明的二元件之安裝裝置，其特 徵為，具有： 第一元件，由合成樹脂材料製成，第一流路向著上側平 坦面開口 ，同時，向著所述上側平坦面而固定配置有由金 屬材料製成、穿透設置有内螺紋孔的内螺紋元件； 第二元件，由金屬材料製成，第二流路向著下側平坦面 開口；和 連接器，由形成平板形的突邊部和圓筒部形成，該突邊 部由金屬材料製成、配置在第一元件的上側平坦面和第二 8 312/發明說明書(補件)/92-10/92120637 1231741 元件的下側平坦面之間，該圓筒部從突邊部向下突出形 成、***配置在第一元件的第一流路内， 連接器的突邊部配置在第一元件的上側平坦面和第二 元件的下側平坦面之間，同時，圓筒部***配置在第一元 件的第一流路内， 利用從第二元件向著内螺紋元件的内螺紋孔螺合配置 的螺釘，藉由内螺紋元件的上端和第二元件的下側平坦 面，夾住連接器的突邊部， 第一元件的第一流路和第二元件的第二流路經連接器 的圓筒部的内面連通，同時，將第一密封元件抵壓配置在 第一元件的第一流路和圓筒部的外圓周之間，將第二密封 元件抵壓配置在第二元件的下側平坦面和突邊部之間。 (作用） 連接器的突邊部，係由固定配置在第一元件上的内螺紋 元件的端部和金屬材料製成的第二元件所夾住，螺釘通過 第二元件和連接器，與内螺紋元件的内螺紋孔螺合，這樣 將第二元件固緊在第一元件上。 由於第一元件的第一流路内的流體通過配置在連接器 的圓筒部和第一流路之間的第一密封元件而保持氣密，因 此，在第一元件的上側平坦面和突邊部的下面之間的洩漏 得以抑制。 另一方面，由於螺釘與内螺紋元件的内螺紋孔螺合，由 金屬材料製成的連接器的突邊部和由金屬材料製成的第二 元件抵壓保持在由金屬材料製成的内螺紋元件的端部上， 9 312/發明說明書(補件)/92-10/92120637 1231741 因此，可以長期地維持穩定的連接緊固力，可以適當的壓 緊力，將第二密封元件抵壓在突邊部的上面，因此可抑制 第二元件的下側平坦面和突邊部上面之間的洩漏。 【實施方式】 以下，參照圖式來說明本發明的二元件之安裝裝置的一 個實施例。 圖1表示將兩個元件連接後的狀態的縱剖面圖。 圖2為連接溺的上部俯視圖。 圖3為沿圖2的A — A線所取的縱剖面圖。 第二元件由金屬材料製成，由於與圖4所示的第二元件 2 0相同，故省略其說明。 (與第二元件2 0有關的元件符號，使用以前的元件符號， 0形環21是指第二密封元件21。另外，第二密封元件21 可以是0形環、方形環等，只要用彈性材料製成並形成環 狀即可）。 元件符號1為用合成樹脂材料製成的第一元件，第一流 路1 B向著上端平坦面1A而開口 。（該第一流路1B面對著 第二元件2 0的第二流路2 Ο B )。 元件符號2為圓筒形，為由内螺紋孔2A貫通内部而穿 透設置的金屬材料製内螺紋元件，該内螺紋元件2在射出 成形第一元件1時，同時内嵌成形，藉此，内螺紋元件2 固定在第一元件1上。 該内螺紋元件2的上端2B配置成與第一元件1的上側 平坦面1 A高度相同，但最好為稍微向上方突出（例如， 10 312/發明說明書(補件)/92-10/92120637 1231741 0.5mm)0 又，内螺紋元件2的内螺紋孔2 A，與第二元件2 0的通 孔2 0 C對應配置，同時沿著通孔2 0 C的長邊軸心方向配置。 在本實施例中，設置有2個通孔2 0 C和2個内螺紋元件2。 另外，内螺紋元件2與第一元件1的固定方法，不僅是 限於上述方法，也可以使用黏接、熱熔接、鉚接等方法。 其次，利用圖2、圖3來說明連接器。 由於連接器3用薄板金屬材料製成，它由作成板狀的突 邊部3A，和從突邊部3A的大致中央部向下方突出的圓筒 部3B構成，在圓筒部3B下端外圓周上，凹入設置有作成 環狀的0形環槽3C。又，元件符號3D為與固定在第一元 件1上的内螺紋元件2的内螺紋孔2 A相對而形成的2個通 孔。該連接器3可通過將0 . 5〜0 . 8 m m的薄板金屬材料拉深 加工而形成。 其次，來說明第一元件1和第二元件2的固接。 第一，將連接器3的突邊部3 A放置在第一元件1的上 側平坦面1 A上，將圓筒部3 B***配置在第一元件1的第 一流路1 B内。 在此狀態下，突邊部3A的通孔3D配置為面向内螺紋元 件2的内螺紋孔2 A，内螺紋元件2的上端2 B與突邊部3 A 的下面頂接配置，並且，0形環等第一密封元件4配置在 圓筒部3 B的0形環槽3 C内。 第二，使第二元件2 0的下側平坦面2 0 A向著連接器3 的突邊部3 A的上面而配置。 11 312/發明說明書(補件)/92-10/92120637 1231741 在這種狀態下，第二元件2 0的通孔2 0 C與連接器3的 通孔3 D相對而配置，同時，第二流路2 Ο B與連接器3的圓 筒部3 B的内側相對而酉己置，配置在0形環槽2 Ο E内的第二 密封元件21，配置在連接器3的突邊部3 A的上面。 然後，通過第二元件2 0的通孔2 0 C、連接器3的通孔 3 D，將螺釘B與内螺紋元件2的内螺紋孔2 A螺合，這樣可 將第二元件2 0與第一元件1連接固緊，因此，連接器3 的突邊部3 A，由第二元件2 0的下側平坦面2 Ο A和第一元 件1的上側平坦面1 A夾住。 根據如上構成，金屬材料製成的第二元件2 0的下側平 坦面2 Ο A，通過由金屬材料製成的連接器3的突邊部3 A， 由螺釘B與固定在第一元件1上的金屬材料製成的内螺紋 元件2的上端2 B螺合，在該螺釘B的連接固定方向上，由 於沒有介入合成樹脂材料，全部為金屬材料製成，因此可 以長期穩定地保持螺釘B的螺合力。 因此，由於第二密封元件2 1，以穩定的抵壓力配置在0 形狀槽2 Ο E内，同時以穩定的抵壓力保持壓緊突邊部3 A 的上面，第一流路1 B、第二流路2 Ο B内的流體不會從第二 元件2 0的下側平坦面2 Ο A和突邊部3 A的上面之間向外部 洩漏。 另夕卜，由於在連接器3的圓筒部3 B的外圓周和第一元 件1的第一流路1 B的内圓周之間，抵壓配置有第一密封元 件4，因此，第一流路1 B、第二流路2 Ο B内的流體不會從 第一元件1的上側平坦面1 A和突邊部3 A的下面之間向外 12 312/發明說明書(補件)/92-10/92〗20637 1231741 洩漏。 如上所述，在連接固緊第一元件1和第二元件2 0後， 可以經過長時間而完全抑制在兩元件1、2 0内形成的流路 1 Β、2 Ο Β和外部之間的洩漏。 又，根據本發明，第二元件2 0仍可使用以往使用的金 屬材料製成的第二元件2 0，因此可以實現元件的共用化， 降低成本。 另外，根據本發明，將内螺紋元件2固定配置在第一元 件1上，和使用由薄板金屬材料形成的連接器3，這樣， 可用合成樹脂材料製造第一元件1，因此，與現有的使用 金屬材料的第一元件1比較，可大大減輕重量。 另外，内螺紋元件2和連接器3由金屬材料製成，但内 螺紋元件2為薄壁中空形狀，連接器3用薄板材料製成， 因此重量增加很小，不會妨礙上述減輕重量的效果。 再者，當用合成樹脂材料製造第一元件1時，與用鋁等 金屬材料製造第一元件1比較，材料費可大大降低，因此 製造成本可降低。 本實施例的第一元件1可在内燃機構的燃料喷射裝置中 使用。可適於用在支持燃料噴射閥的燃料分配管（輸送管） 上，第二元件2 0適於用在對流過燃料分配管的燃料壓力加 以調整的壓力控制閥（壓力調節器）上。 (發明效果） 如上所述，本發明的二元件之安裝裝置具有：第一元 件，由合成樹脂材料製成、第二流路向著上側平坦面開口、 13 312/發明說明書(補件)/92-10/92120637 1231741 穿透設置有内螺紋孔的内螺紋元件向著上側平坦面而固定 配置；連接器，由薄板金屬材料製成、平板狀的突邊部和 圓筒部從突邊部向著下方而連續設置；和第二元件，由金 屬材料製成，具有向著下側平坦面而開口的第一流路，連 接器的突邊部配置在第一元件的上側平坦面上，同時，連 接器的圓筒部***配置在第一元件的第一流路内，第二元 件的下側平坦面配置在突邊部的上面，通過經第二元件將 螺釘螺合於内螺紋元件的内螺紋孔中，這樣將連接器的突 邊部、第二元件螺合連接在内螺紋元件的上端，可用在長 時間内穩定的連接緊固力，將金屬材料製第二元件連接在 用合成樹脂材料製造的第一元件上。 另外，利用配置在連接器圓筒部和第一元件的第一流路 之間的第一密封元件，可以完全抑制内部流體向外洩漏， 利用配置在突邊部和第二元件的下側平坦面之間的第二密 封元件，也可完全抑止流體向外洩漏。 如上所述，第二元件可以使用以往使用的由金屬材料製 成的第二元件，另一方面，可用合成樹脂材料製造第一元 件。這樣，可以共用元件，降低材料費，降低製品的製造 成本。 用合成樹脂材料製造第一元件，可減輕製品重量，特別 是在内燃機構所用的燃料供給裝置中有效。 【圖式簡單說明】 圖1為顯示本發明的二元件之安裝裝置的一個實施例的 縱剖面圖。 14 312/發明說明書(補件)/92-10/92120637 1231741 圖2為圖1所用的連接器的上部俯視圖。

belongs] The present invention relates to a two-element mounting device for screwing a flat surface formed on a first element and a flat surface formed on a second element by screws, Among them, it particularly relates to a mounting device for two components that connects a first flow path opened on a flat surface of a first element and a second flow path opened on a second flat surface. [Prior Art] FIG. 4 shows a conventional two-element mounting device. The element symbol 10 is a first element which is a connected element, and is made of a metal material such as aluminum. The first element 10 is formed at its upper end with an upper flat surface 10 A, and from the inside of the first element 10 toward the upper flat surface 10 A, an opening forms a first flow path 10 B. In addition, an internally threaded hole 1 0 C is penetratingly provided at an upper flat surface 10 A of a side surface of the first flow path 10C, and more specifically, a plurality of internally threaded holes 10C are penetratingly provided to include the upper side. The flange portion 10 D of the flat surface 10A. The component symbol 20 is a second component which is another component to be connected, and is also made of a metal material such as aluminum. A lower flat surface 20 A is formed at the lower end of the second element 20, and a second flow path 20B is formed by opening from the inside of the second element 20 toward the lower flat surface 20 A. A through hole 2 0 C corresponding to the internally threaded hole 1 0 C is formed on the lower flat surface 2 〇 A of the side surface of the second flow path 2 〇 B. A plurality of through holes 2 0 C are provided in a penetrating manner. The flange portion 20 D including the lower flat surface 2 0 A is included. In addition, the second flow path 2 0 B, which is open on the lower flat surface 2 0 A, is shaped as 6 312 / Invention Specification (Supplement) / 92-10 / 9212063 7 1231741 into 0-shaped ring groove 2 0 E, 0-shaped The ring 21 is placed in the 0-ring groove. The first element 10 and the second element 20 are connected as follows. That is, the lower flat surface 2 A of the second element 20 is placed on the upper flat surface 1 A of the first element 10 in an abutting manner. In this state, the through-hole 20 C is directed toward the internally threaded hole. 1 0 C Tighten the screw B. In this way, since the first element 10 and the second element 20 have flat surfaces 10 A and 2 A, respectively, and are screwed and fastened, at this time, the first flow path 1 opened on the upper flat surface 10 A 0 B and the second flow path 2 0 B opened on the lower flat surface 20 A, and the flow paths are connected by the above-mentioned abutment surface. In this connection state, the 0-ring 2 1 arranged in the 0-ring groove 20 E of the second element 20 is pressed against the upper flat surface 1 0 A of the first element 10 to suppress the Leakage of fluid in the above-mentioned flow path from the first flow path 10 B and the second flow path 20 B through the abutting surfaces of the upper flat surface 10 A and the lower flat surface 20 A. SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) In such a two-component mounting device, it is strongly desired to reduce the manufacturing cost and the weight of the device. Therefore, first, it is desirable to use the existing components together. Second, in order to reduce material costs and weight, components can be manufactured from synthetic resin materials. That is, the second element 20 is shared for the purpose of sharing. And the first element 10 is made of a synthetic resin material. This is equivalent to manufacturing the first element 312 / Invention Specification (Supplement) / 92-10 / 92120637 1231741 pieces 10 from a synthetic resin material in the state shown in FIG. 4. That is, since the second component 20 made of a metal material is fixed to the first component 10 made of a synthetic resin material by a screw B, the screw B is connected over time. The tightening force is reduced (due to the low creep resistance of the synthetic resin material), between the upper flat surface 1 0 A of the first element 10 and the lower flat surface 2 0 A of the second element 20 The reduced pressure reduces the sealing function produced by the O-ring 21. Therefore, the fluid in the first flow path 10 B and the second flow path 2 0 B will generate a top from the upper flat surface and the lower flat surface 20A. The interface is facing the bad condition of external leakage. The present invention has been made in consideration of the above-mentioned problems of a two-component mounting device, and an object thereof is to provide the above-mentioned device. It can reduce the manufacturing cost and weight by connecting the flow path and tightening it. (Means for Solving the Problem) In order to achieve the above-mentioned object, the two-element mounting device of the present invention is characterized by having: a first element made of a synthetic resin material; a first flow path opening toward an upper flat surface; The upper flat surface is fixedly provided with an internally threaded element made of a metal material and penetratingly provided with an internally threaded hole; a second element made of a metal material with a second flow path opening toward the lower flat surface; and a connection The device is formed by a flange portion and a cylindrical portion formed in a flat plate shape. The flange portion is made of a metal material and is arranged on the upper flat surface of the first element and the second 8 312 / Invention Specification (Supplement) / 92- 10/92120637 1231741 Between the lower flat surfaces of the element, the cylindrical portion protrudes downward from the flange portion, is inserted into the first flow path of the first element, and the flange portion of the connector is arranged on the first element. Between the upper flat surface and the lower flat surface of the second element, at the same time, the cylindrical portion is inserted into the first flow path of the first element, and the screw threaded from the second element to the internally threaded hole of the internally threaded element is screwed. With the upper end of the internally threaded element and the lower flat surface of the second element sandwiching the flange portion of the connector, the first flow path of the first element and the second flow path of the second element pass through the cylindrical portion of the connector. At the same time, the first sealing element is arranged between the first flow path of the first element and the outer circumference of the cylindrical portion while the second sealing element is arranged on the lower flat surface of the second element and Between the flanges. (Action) The protruding portion of the connector is clamped by the end of the internally threaded element fixedly arranged on the first element and the second element made of metal material. The screw passes through the second element and the connector to the inner part. The internally threaded hole of the threaded element is screwed, so that the second element is fastened on the first element. Since the fluid in the first flow path of the first element is kept airtight by the first sealing element arranged between the cylindrical portion of the connector and the first flow path, the upper flat surface and the flange portion of the first element Leakage between the underside was suppressed. On the other hand, since the screw is screwed with the internally threaded hole of the internally threaded element, the flange portion of the connector made of a metal material and the second element made of the metal material are pressed against and held inside the metal material. On the end of the threaded element, 9 312 / Invention Specification (Supplement) / 92-10 / 92120637 1231741 Therefore, a stable connection fastening force can be maintained for a long period of time, and a proper pressing force can be used to press the second sealing element. On the upper surface of the flange portion, leakage between the lower flat surface of the second element and the upper surface of the flange portion can be suppressed. [Embodiment] Hereinafter, an embodiment of a two-component mounting device according to the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a state where two elements are connected. Figure 2 is a top plan view of the connection. Fig. 3 is a longitudinal sectional view taken along the line A-A in Fig. 2. The second element is made of a metal material, and its description is omitted because it is the same as the second element 20 shown in FIG. 4. (The component symbols related to the second component 20 use the previous component symbols. The 0-ring 21 refers to the second sealing element 21. In addition, the second sealing element 21 may be a 0-ring, a square ring, etc., as long as it is elastic The material can be made into a ring). The reference numeral 1 is a first element made of a synthetic resin material, and the first flow path 1 B is opened toward the upper flat surface 1A.

The female threaded element 2 is formed by insert molding when the first element 1 is injection-molded. The internally threaded element 2 is fixed on the first element 1. The upper end 2B of the internally threaded element 2 is arranged to have the same height as the upper flat surface 1 A of the first element 1, but it is preferable to protrude slightly upward (for example, 10 312 / Invention Specification (Supplement) / 92-10 / 92120637 1231741 0.5mm) 0 The internally threaded hole 2 A of the internally threaded element 2 is arranged corresponding to the through-hole 2 0 C of the second element 20, and is arranged along the long axis direction of the through-hole 20 C. In this embodiment, two through holes 2 0 C and two internally threaded elements 2 are provided. In addition, the method of fixing the internally threaded element 2 and the first element 1 is not limited to the above-mentioned method, and methods such as adhesion, heat welding, and riveting may be used. Next, the connector will be described using FIG. 2 and FIG. 3. Since the connector 3 is made of a thin plate metal material, it is composed of a plate-shaped flange portion 3A and a cylindrical portion 3B protruding downward from a substantially central portion of the flange portion 3A. The outer circumference of the lower end of the cylindrical portion 3B On the upper side, a ring-shaped 0-ring groove 3C is recessed. The element symbol 3D is two through holes formed to face the internally threaded hole 2 A of the internally threaded element 2 fixed to the first element 1. The connector 3 can be formed by deep-drawing a sheet metal material of 0.5 to 0.8 mm. Next, the fixation of the first element 1 and the second element 2 will be described. First, the flange portion 3A of the connector 3 is placed on the upper flat surface 1A of the first element 1, and the cylindrical portion 3B is inserted into and arranged in the first flow path 1B of the first element 1. In this state, the through hole 3D of the flange portion 3A is arranged to face the female screw hole 2 A of the female threaded element 2, and the upper end 2 B of the female threaded element 2 is in abutment with the lower surface of the flanged portion 3 A, and 0 The first sealing element 4 such as a ring is disposed in the 0-ring groove 3 C of the cylindrical portion 3 B. Second, the lower flat surface 20 A of the second element 20 is arranged toward the upper surface of the flange portion 3 A of the connector 3. 11 312 / Invention Specification (Supplement) / 92-10 / 92120637 1231741 In this state, the through hole 2 0 C of the second element 20 is arranged opposite to the through hole 3 D of the connector 3, and at the same time, the second The flow path 2 Ο B is opposed to the inside of the cylindrical portion 3 B of the connector 3, and the second sealing element 21 is disposed in the 0-ring groove 2 Ο E, and is disposed at the flange portion 3 of the connector 3 The top of A. Then, through the through-hole 20 C of the second component 20 and the through-hole 3 D of the connector 3, screw the screw B with the internally threaded hole 2 A of the internally threaded component 2, so that the second component 20 and the The first element 1 is firmly connected. Therefore, the protruding portion 3 A of the connector 3 is sandwiched by the lower flat surface 20 A of the second element 20 and the upper flat surface 1 A of the first element 1. According to the above configuration, the lower flat surface 20A of the second element 20 made of a metal material passes through the flange portion 3A of the connector 3 made of the metal material, and is fixed to the first element 1 by the screw B The upper end 2 B of the internally threaded element 2 made of metal material is screwed. In the connection and fixing direction of the screw B, since no synthetic resin material is involved, all the metal material is used, so the screw B can be stably maintained for a long time. Screw force. Therefore, since the second sealing element 21 is arranged in the 0-shaped groove 2 0 E with a stable abutment pressure, and the upper surface of the pressing protrusion 3 A is maintained with a stable abutment pressure, the first flow path 1 B, the second The fluid in the flow path 2 O B does not leak to the outside from between the lower flat surface 2 A of the second element 20 and the upper surface of the flange portion 3 A. In addition, since the first sealing element 4 is arranged to be pressed between the outer circumference of the cylindrical portion 3 B of the connector 3 and the inner circumference of the first flow path 1 B of the first element 1, the first flow path 1 B, the second flow path 2 〇 The fluid in B does not go outward from between the upper flat surface 1 A of the first element 1 and the lower surface of the flange portion 3 A 12 312 / Invention Specification (Supplement) / 92- 10/92〗 20637 1231741 Leak. As described above, after the first element 1 and the second element 20 are connected and fastened, the flow paths 1 Β, 20 Β formed between the two elements 1 and 20 and the outside can be completely suppressed after a long time. leakage. In addition, according to the present invention, the second element 20 can still use the second element 20 made of a metal material that has been conventionally used, so that the elements can be shared and the cost can be reduced. In addition, according to the present invention, the internally threaded element 2 is fixedly disposed on the first element 1 and the connector 3 formed of a thin plate metal material is used. In this way, the first element 1 can be manufactured from a synthetic resin material, and therefore, it is similar to the conventional use Compared with the first element 1 made of metal, the weight can be greatly reduced. In addition, the internally threaded element 2 and the connector 3 are made of a metal material, but the internally threaded element 2 is a thin-walled hollow shape, and the connector 3 is made of a thin plate material, so the weight increase is small, and the aforementioned weight reduction effect will not be hindered. . Furthermore, when the first element 1 is manufactured from a synthetic resin material, compared with manufacturing the first element 1 from a metal material such as aluminum, the material cost can be greatly reduced, and therefore the manufacturing cost can be reduced. The first element 1 of this embodiment can be used in a fuel injection device of an internal combustion engine structure. It is suitable for use in a fuel distribution pipe (delivery pipe) supporting a fuel injection valve, and the second element 20 is suitable for use in a pressure control valve (pressure regulator) that adjusts the pressure of the fuel flowing through the fuel distribution pipe. (Effects of the Invention) As described above, the two-component mounting device of the present invention has the first component made of a synthetic resin material, the second flow path opening toward the upper flat surface, 13 312 / Invention Specification (Supplement) / 92 -10/92120637 1231741 The internally threaded element provided with an internally threaded hole is fixedly arranged toward the upper flat surface; the connector is made of a thin metal material, and the flat flange portion and the cylindrical portion are downward from the flange portion And the second element is made of a metal material and has a first flow path opening toward the lower flat surface, and the protruding portion of the connector is arranged on the upper flat surface of the first element; The cylindrical portion is inserted and disposed in the first flow path of the first element, and the lower flat surface of the second element is disposed on the upper side of the flange portion, and the screw is screwed into the internally threaded hole of the internally threaded element through the second element. In this way, the flange portion of the connector and the second element are screw-connected to the upper end of the internally threaded element, and the second element made of metal material can be connected to the synthetic resin material by a stable connection fastening force over a long period of time. The first element manufactured. In addition, the first sealing element disposed between the cylindrical portion of the connector and the first flow path of the first element can completely prevent the internal fluid from leaking outward, and the flat surface disposed under the flange portion and the second element is used. The second sealing element in between can also completely prevent the fluid from leaking outward. As described above, the second element may be a second element made of a metal material that has been conventionally used. On the other hand, the first element may be made of a synthetic resin material. In this way, components can be shared, material costs can be reduced, and manufacturing costs of products can be reduced. Manufacture of the first element from a synthetic resin material can reduce the weight of the product, and is particularly effective in a fuel supply device for an internal combustion engine mechanism.
