図3に示されているように、プラグ部材17はプランジャチューブ16の外径とほぼ同一径で、プランジャチューブ16に連続する円柱部41と、円柱部41の上端面側に形成された非円形の回転止め部43とを有する。回転止め部43は、円柱部41より小径で、図6に示されているように、挿入孔28と同様の平行2面取り部42を有する小判形に形成されている。回転止め部43の輪郭及び寸法は、挿入孔28の形状及び寸法とほぼ同じで、回転止め部43が挿入孔28に嵌合可能になっている。   As shown in FIG. 3, the plug member 17 has substantially the same diameter as the outer diameter of the plunger tube 16, a cylindrical portion 41 continuous with the plunger tube 16, and a non-circular shape formed on the upper end surface side of the cylindrical portion 41. And a rotation stopper 43. The rotation stopper 43 has a smaller diameter than the cylindrical portion 41 and is formed in an oval shape having a parallel two chamfered portion 42 similar to the insertion hole 28 as shown in FIG. The outline and dimensions of the rotation stopper 43 are substantially the same as the shape and dimensions of the insertion hole 28, and the rotation stopper 43 can be fitted into the insertion hole 28.

円柱部41と回転止め部43との段差部分により、円柱部41の軸方向における端面44が形成されている。回転止め部43の端面には先太のテーパ軸部45が形成されている。テーパ軸部45のテーパ面(傾斜面)45Aと回転止め部43の端面43Aとにより係合溝46が画定されている。   An end surface 44 in the axial direction of the cylindrical portion 41 is formed by the step portion between the cylindrical portion 41 and the rotation stopper 43. A taper shaft 45 having a thick tip is formed on the end face of the rotation stopper 43. An engaging groove 46 is defined by the tapered surface (inclined surface) 45 </ b> A of the tapered shaft portion 45 and the end surface 43 </ b> A of the rotation stopper 43.

テーパ軸部45の先端には、先端外周縁をR加工(R面47)された頭部48が形成されている。図4に示されている係合溝46の小径側直径DaminとR面47の小径側直径Dbminは、ともに抜け止め係止状態(係合溝46と係合していない状態)での円弧形状部35Aと36Aの内側の間隔寸法tより小さく、係合溝46の大径側直径DamaxとR面47の大径側直径Dbmaxは、ともに抜け止め係止状態(係合溝46と係合していない状態)での円弧形状部35Aと36Aの内側の間隔寸法tより大きい。   At the tip of the taper shaft portion 45, a head 48 is formed by rounding the outer periphery of the tip (R surface 47).

Is larger than the distance t between the arcuate portions 35A and 36A.

つぎに、電磁コイルユニット21の取付手順を説明する。図3に示されているように、挿入孔28の平行2面取り部27の位置と回転止め部43の平行2面取り部42の位置とがガイド部材17の周方向において一致するようにした状態で、電磁コイルユニット21を、外凾22の下片22A側から円筒部(プラグ部材17+プランジャチューブ16)の外周に嵌装する。換言すれば、電磁コイルユニット21の挿入孔24、25、28に、円筒部(プラグ部材17+プランジャチューブ16)を挿入孔24の側から挿入する。   Next, a procedure for attaching the electromagnetic coil unit 21 will be described. As shown in FIG. 3, the position of the parallel two chamfered portion 27 of the insertion hole 28 and the position of the parallel two chamfered portion 42 of the rotation stopper 43 are aligned in the circumferential direction of the guide member 17. The electromagnetic coil unit 21 is fitted on the outer periphery of the cylindrical portion (plug member 17 + plunger tube 16) from the lower piece 22A side of the outer casing 22. In other words, the cylindrical portion (plug member 17 + plunger tube 16) is inserted into the insertion holes 24, 25, and 28 of the electromagnetic coil unit 21 from the insertion hole 24 side.

この嵌装(挿入)によってプラグ部材17の頭部48が電磁コイルユニット21の挿入孔28の部分に到達すると、頭部48のR面47が係止線材31の中間部35、36、特に、円弧形状部35A、36Aに当接する。これより、さらに、挿入(押し込み)を行うと、R面47に案内されて係止線材31の中間部35、36が外側(互いに離間する方向)に押し広げられる。   When the head portion 48 of the plug member 17 reaches the insertion hole 28 of the electromagnetic coil unit 21 by this fitting (insertion), the R surface 47 of the head portion 48 is connected to the intermediate portions 35 and 36 of the locking wire 31, It contacts the arcuate portions 35A, 36A. Accordingly, when the insertion (pushing) is further performed, the intermediate portions 35 and 36 of the locking wire 31 are pushed outward (in a direction away from each other) by being guided by the R surface 47.

そして、係止線材31の中間部35、36(円弧形状部35A、36A)が頭部48を乗り越えてテーパ軸部45のテーパ面(傾斜面)45Aに差しかかると、中間部35、36が係合溝46に、これを両側から挟むようにして径方向の弾性変形状態で落ち込み係合する。これと同時に、ガイド部材17の周方向における両平行2面取り部27、42の位置が一致していることから、回転止め形状の挿入孔28に回転止め部43が整合係合する。   When the intermediate portions 35 and 36 (arc-shaped portions 35A and 36A) of the locking wire 31 get over the head 48 and come into contact with the tapered surface (inclined surface) 45A of the tapered shaft portion 45, the intermediate portions 35 and 36 are The engagement groove 46 is engaged by being depressed in an elastically deformed state in the radial direction so as to be sandwiched from both sides. At the same time, since the positions of the two parallel chamfered portions 27 and 42 in the circumferential direction of the guide member 17 coincide with each other, the rotation stopper 43 is aligned and engaged with the rotation stopper-shaped insertion hole 28.

上述の如く、係止線材31の中間部35、36が係合溝46に径方向の弾性変形状態で係合することにより、径方向のがた付きを含むことなく、電磁コイルユニット21が弁ハウジング11側の円筒部(プラグ部材17+プランジャチューブ16)に抜け止め固定される。   As described above, when the intermediate portions 35 and 36 of the locking wire 31 are engaged with the engagement groove 46 in the elastically deformed state in the radial direction, the electromagnetic coil unit 21 can be operated without including the radial backlash. It is fixed to the cylindrical portion (plug member 17 + plunger tube 16) on the housing 11 side to prevent it from coming off.

これと同時に、係止線材31が弾性変形によるばね荷重によって傾斜面であるテーパ面(溝面)45Aに押し付けられることにより、ガイド部材17の軸線方向分力(頭部48を上方へ持ち上げる方向の力)が、円筒部(プラグ部材17+プランジャチューブ16)と電磁コイルユニット21との間に発生する。この軸線方向分力によって、図4に示されているように、プラグ部材17の円柱部41と回転止め部43との段差部分に設けられている端面44が、上片22Bの下端面37に押し付けられる。これにより、電磁コイルユニット21が軸線方向のがた付きを含むことなく円筒部(プラグ部材17+プランジャチューブ16)に固定される。   At the same time, the locking wire 31 is pressed against the tapered surface (groove surface) 45A, which is an inclined surface, by a spring load caused by elastic deformation, whereby the axial force component of the guide member 17 (in the direction of lifting the head 48 upward). Force) is generated between the cylindrical portion (plug member 17 + plunger tube 16) and the electromagnetic coil unit 21. Due to this axial force component, as shown in FIG. 4, the end surface 44 provided at the step portion between the cylindrical portion 41 and the rotation stop portion 43 of the plug member 17 becomes the lower end surface 37 of the upper piece 22B. Pressed. As a result, the electromagnetic coil unit 21 is fixed to the cylindrical portion (plug member 17 + plunger tube 16) without including any backlash in the axial direction.

そして、上述の電磁コイルユニット21の取り付けは、電磁コイルユニット21の挿入孔24、25、28に、円筒部(プラグ部材17+プランジャチューブ16)を挿入孔24の側から挿入するだけで、何の工具も必要とすることなく、ワンタッチで、簡便、且つ確実に行われる。   The above-described electromagnetic coil unit 21 can be attached by simply inserting the cylindrical portion (plug member 17 + plunger tube 16) into the insertion holes 24, 25, and 28 of the electromagnetic coil unit 21 from the insertion hole 24 side. It is simple and reliable with one touch without the need for tools.

さらには、これと同時に、回転止め形状の挿入孔28と回転止め部43との整合係合によって電磁コイルユニット21の回転止めも行われる。なお、挿入孔28、回転止め部43の回転止め形状は、図示されているような、小判形に限られることはなく、長円、四角形、六角形、星形等であってよい。   Furthermore, at the same time, the rotation of the electromagnetic coil unit 21 is also stopped by the alignment engagement between the rotation-preventing insertion hole 28 and the rotation stopper 43. The rotation stop shapes of the insertion hole 28 and the rotation stop portion 43 are not limited to the oval shape as illustrated, and may be an ellipse, a quadrangle, a hexagon, a star, or the like.

なお、係合溝46の溝面は、テーパ面45Aに限られることはなく、図9に示されているように、R面49であってもよく、上述の実施形態と同様の作用、効果を得ることがてきる。さらには、係合溝46は、図10に示されているように、抜け止め強化の矩形断面部46Aとテーパ面45Aとの組み合わせ形状であってよい。   The groove surface of the engagement groove 46 is not limited to the tapered surface 45A, but may be an R surface 49 as shown in FIG. 9, and the same operation and effect as in the above-described embodiment. You can get Furthermore, as shown in FIG. 10, the engagement groove 46 may have a combined shape of a rectangular cross-section portion 46A and a taper surface 45A for reinforcing removal.

また、頭部48の先端外周縁は、R加工(R面47)以外に、図11に示されているように、面取り加工(面取り面50)形成されていてもよい。この場合も、ワンタッチ取り付けのために、面取り面50の小径側直径Dbminは、抜け止め係止状態(係合溝46と係合していない状態)での円弧形状部35Aと36Aの内側の間隔寸法tより小さく、面取り面50の大径側直径Dbmaxは、ともに抜け止め係止状態(係合溝46と係合していない状態)での円弧形状部35Aと36Aの内側の間隔寸法tより大きい。   Further, the tip outer peripheral edge of the head 48 may be chamfered (chamfered surface 50) as shown in FIG. 11 in addition to the R process (R surface 47). Also in this case, for the one-touch attachment, the small diameter side diameter Dbmin of the chamfered surface 50 is an interval between the arc-shaped portions 35A and 36A in the retaining lock state (a state where the chamfered surface is not engaged with the engagement groove 46). The large-diameter side diameter Dbmax of the chamfered surface 50 is smaller than the dimension t, both from the distance dimension t inside the arcuate portions 35A and 36A in the retaining lock state (not engaged with the engagement groove 46). large.

なお、面取り面50は、45度傾斜のものに限られることはなく、上述の小径側直径Dbmin、大径側直径Dbmaxと円弧形状部35Aと36Aの内側の間隔寸法tとの関係を保つ範囲で、いかなる傾斜度の傾斜面であってもよい。   In addition, the chamfered surface 50 is not limited to the one inclined at 45 degrees, and the range in which the relationship between the small diameter side diameter Dbmin and the large diameter side diameter Dbmax described above and the distance t between the arcuate portions 35A and 36A is maintained. Thus, the inclined surface may have any inclination.

また、係止線材31の抜け止めは、図12に示されているように、折曲部32、33が上片22Bに形成された丸孔51、52に係合することにより、あるいは、図13に示されているように、折曲部32、33が上片22Bに形成された長孔53に係合することにより行われてもよい。また、図14、図15に示されているように、係止線材31は、外側へのばね力によってブリッジ状の嵌め込み装着部29、30の内面に押さえ付けられ、係止線材31の中間部35、36(二つの嵌め込み装着部29、30間に位置する部分)が段差形状になっていることにより抜け止めされる形態をとることもできる。   Further, as shown in FIG. 12, the retaining wire 31 is prevented from coming off by engaging the bent portions 32 and 33 with the round holes 51 and 52 formed in the upper piece 22B, or 13, the bent portions 32 and 33 may be engaged with a long hole 53 formed in the upper piece 22B. Further, as shown in FIGS. 14 and 15, the locking wire 31 is pressed against the inner surface of the bridge-like fitting mounting portions 29 and 30 by the spring force to the outside, and the intermediate portion of the locking wire 31 35 and 36 (part located between the two fitting attachment parts 29 and 30) can also take the form which is prevented from falling out by having a step shape.

また、係止線材31は、一方の中間部35にのみ円弧形状部35Aが形成され他方の中間部36の円弧形状部36Aが省略されたものであったり、図16に示されているように、円弧形状部に代えて山形折曲部35Bとしたものであったり、あるいは図17に示されているように、中間部35、36のいずれもにも円弧形状部が形成されていないものであってもよい。   In addition, the locking wire 31 is formed such that the arc-shaped portion 35A is formed only in one intermediate portion 35 and the arc-shaped portion 36A of the other intermediate portion 36 is omitted, or as shown in FIG. Instead of the arc-shaped portion, a mountain-shaped bent portion 35B is used, or as shown in FIG. 17, neither of the intermediate portions 35, 36 is formed with an arc-shaped portion. There may be.

また、係止線材31は、図18に示されているように、両中間部35、36を接続するターン部39が傾斜角θをもって傾斜しているものであってもよい。この場合には、係止線材31と外凾22との間のがた付きを完全になくすことができる。   Further, as shown in FIG. 18, the locking wire 31 may be one in which a turn part 39 connecting both the intermediate parts 35 and 36 is inclined with an inclination angle θ. In this case, rattling between the locking wire 31 and the outer casing 22 can be completely eliminated.

また、係止線材31は、図19に示されているように、両端部54,55を上片22の上面にスポット溶接されたものであってもよく、さらに、図20に示されているように、円弧形状部に代えてコの字形等のばね性強化形状部56を両端部54,55の間に備えているものであってもよい。これらのように係止線材31を構成する場合、図19や図20に示されているように頭部48の一側のみに係止線材31を設けるのではなく、頭部48の両側に各々係止線材31を設けるようにすることもできる。   Further, as shown in FIG. 19, the locking wire 31 may be one in which both end portions 54 and 55 are spot-welded to the upper surface of the upper piece 22, and further shown in FIG. Thus, instead of the arc-shaped portion, a spring-enhanced shape portion 56 such as a U-shape may be provided between both end portions 54 and 55. When the locking wire 31 is configured as described above, the locking wire 31 is not provided only on one side of the head 48 as shown in FIG. 19 and FIG. A locking wire 31 can also be provided.

図21、図22は、この発明による電磁コイル取付構造の他の実施形態を示している。なお、図21、図22において、図1〜図8に対応する部分は、図1〜図8に付した符号と同一の符号を付けて、その説明を省略する。   21 and 22 show another embodiment of the electromagnetic coil mounting structure according to the present invention. 21 and 22, parts corresponding to those in FIGS. 1 to 8 are denoted by the same reference numerals as those in FIGS. 1 to 8, and description thereof is omitted.

この実施形態では、プラグ部材17の頭部148が先細のテーパ軸状に形成され、その外周面を傾斜した平行2面取り(平行2面取り部61)されている。平行2面取り部61は回転止め部43の平行2面取り部42と同一の周方向位置にある。これにより、頭部148は横断面形状が回転止め部43と整合する非円形(小判形)の先細の平行2面取り錐体62をなす。   In this embodiment, the head portion 148 of the plug member 17 is formed in a tapered taper shaft shape, and the outer peripheral surface thereof is inclined in parallel two chamfers (parallel two chamfered portion 61). The parallel two chamfered portion 61 is at the same circumferential position as the parallel two chamfered portion 42 of the rotation stopper 43. Thus, the head 148 forms a non-circular (oval) tapered parallel two-chamfered cone 62 whose cross-sectional shape is aligned with the rotation stopper 43.

傾斜面である平行2面取り部61の最大幅Tmaxは小判形の挿入孔28の平行2面取り部27の内側の間隔寸法sより少し小さく、平行2面取り部61の最小幅Tminは最大幅Tmaxよりさらに小さい。なお、平行2面取り部61の最大幅Tmaxは、回転止め部43の平行2面取り部42の幅寸法と同等であってよい。   The maximum width Tmax of the parallel two-chamfered portion 61 that is an inclined surface is slightly smaller than the interval dimension s inside the parallel two-chamfered portion 27 of the oval insertion hole 28, and the minimum width Tmin of the parallel two-chamfered portion 61 is larger than the maximum width Tmax. Even smaller. Note that the maximum width Tmax of the parallel two-chamfered portion 61 may be equal to the width dimension of the parallel two-chamfered portion 42 of the rotation stopper 43.

この実施形態では、電磁コイルユニット21側の挿入孔28にプラグ先端を挿入する際に、最初に、平行2面取り錐体62と挿入孔28の小判形状が互いに整合する状態にして電磁コイルユニット21を円筒部(プラグ部材17+プランジャチューブ16)の外周に嵌装する。   In this embodiment, when the plug tip is inserted into the insertion hole 28 on the electromagnetic coil unit 21 side, first, the parallel two-chamfered cone 62 and the oval shape of the insertion hole 28 are in alignment with each other. Is fitted on the outer periphery of the cylindrical portion (plug member 17 + plunger tube 16).

この嵌装は、平行2面取り錐体62と挿入孔28との係合によって回り止め状態で行われ、真っ直ぐの挿入により、挿入孔28と回転止め部43との係合が、その後の回転方向の位置あわせを行うことなく、双方の平行2面取り部27、42が合った状態で円滑に行われる。   This fitting is performed in a non-rotating state by the engagement between the parallel two-chamfered cone 62 and the insertion hole 28, and by the straight insertion, the engagement between the insertion hole 28 and the rotation preventing portion 43 is performed in the subsequent rotation direction. Is performed smoothly in a state where the two parallel chamfered portions 27 and 42 are aligned.

この嵌装(挿入)過程で、係止線材31の中間部35,36は、平行2面取り錐体62の傾斜面である平行2面取り部61に案内されて外側に押し広げられ、平行2面取り部61の最大幅部を乗り越えることにより、前述の実施形態と同様に、係合溝46に落ち込み係合する。   During this fitting (insertion) process, the intermediate portions 35 and 36 of the locking wire 31 are guided by the parallel two-chamfered portion 61 that is the inclined surface of the parallel two-chamfered conical body 62 and are spread outwardly, so that two parallel chamfers are formed. By climbing over the maximum width portion of the portion 61, the engagement is lowered into the engagement groove 46 as in the above-described embodiment.

したがって、この実施形態でも、前述した実施形態と同等の作用、効果が得られる。   Therefore, this embodiment can provide the same operations and effects as the above-described embodiment.

図23は、この発明による電磁コイル取付構造の他の実施形態を示している。なお、図23において、図1〜図8に対応する部分は、図1〜図8に付した符号と同一の符号を付けて、その説明を省略する。   FIG. 23 shows another embodiment of the electromagnetic coil mounting structure according to the present invention. 23, parts corresponding to those in FIGS. 1 to 8 are denoted by the same reference numerals as those in FIGS. 1 to 8, and description thereof is omitted.

この実施形態では、小判形の回転止め部43の端面に形成された先太のテーパ軸部45のテーパ面(傾斜面)45A上に円柱状の頭部148Aが形成され、この頭部148Aに、回転止め部43の平行2面取り部42と同等の幅寸法で平行2面取り(平行2面取り部63)され、各平行2面取り部63の上縁部に先細のテーパ面(傾斜面)45Bが形成されている。平行2面取り部63は回転止め部43の平行2面取り部42と同一の周方向位置にある。   In this embodiment, a columnar head portion 148A is formed on a tapered surface (inclined surface) 45A of a thick tapered shaft portion 45 formed on an end surface of an oval rotation stopper 43, and this head portion 148A is formed on the head portion 148A. The two parallel chamfered portions (parallel two chamfered portions 63) having the same width dimension as the parallel two chamfered portions 42 of the rotation stop portion 43, and a tapered tapered surface (inclined surface) 45B is formed on the upper edge portion of each parallel two chamfered portion 63. Is formed. The parallel two chamfered portion 63 is at the same circumferential position as the parallel two chamfered portion 42 of the rotation stopper 43.

この実施形態では、電磁コイルユニット21側の挿入孔28にプラグ先端を挿入する際に、最初に、平行2面取り部63と挿入孔28の小判形状が互いに整合する状態にして電磁コイルユニット21を円筒部(プラグ部材17+プランジャチューブ16)の外周に嵌装する。   In this embodiment, when inserting the plug tip into the insertion hole 28 on the electromagnetic coil unit 21 side, the electromagnetic coil unit 21 is first set in a state where the parallel two-chamfered portion 63 and the oval shape of the insertion hole 28 are aligned with each other. It is fitted on the outer periphery of the cylindrical portion (plug member 17 + plunger tube 16).

この嵌装は、平行2面取り部63と挿入孔28との係合によって回り止め状態で行われ、真っ直ぐの挿入により、挿入孔28と回転止め部43との係合が、その後の回転方向の位置あわせを行うことなく、双方の平行2面取り部27、42が合った状態で円滑に行われる。   This fitting is performed in a non-rotating state by the engagement between the parallel two chamfered portion 63 and the insertion hole 28, and by the straight insertion, the engagement between the insertion hole 28 and the rotation preventing portion 43 is performed in the subsequent rotation direction. Without the alignment, the two parallel chamfered portions 27 and 42 are smoothly aligned.

この嵌装(挿入)過程で、係止線材31の中間部35,36は、平行2面取り部63に連なるテーパ面45Bに案内されて外側に押し広げられ、平行2面取り部63を乗り越えてテーパ軸部45のテーパ面(傾斜面)45Aに差しかかると、中間部35、36がテーパ面(傾斜面)45Aに、これを両側から挟むようにして径方向の弾性変形状態で落ち込み係合する。これと同時に、ガイド部材17の周方向における両平行2面取り部27、42の位置が一致していることから、回転止め形状の挿入孔28に回転止め部43が整合係合する。   In this fitting (insertion) process, the intermediate portions 35 and 36 of the locking wire 31 are guided by the taper surface 45 </ b> B connected to the parallel two-chamfered portion 63, spread outward, and get over the parallel two-chamfered portion 63 to taper. When approaching the taper surface (inclined surface) 45A of the shaft portion 45, the intermediate portions 35 and 36 are engaged with the taper surface (inclined surface) 45A in a state of being elastically deformed in the radial direction so as to be sandwiched from both sides. At the same time, since the positions of the two parallel chamfered portions 27 and 42 in the circumferential direction of the guide member 17 coincide with each other, the rotation stopper 43 is aligned and engaged with the rotation stopper-shaped insertion hole 28.

上述の如く、係止線材31の中間部35、36がテーパ面(傾斜面)45Aに径方向の弾性変形状態で係合することにより、径方向のがた付きを含むことなく、電磁コイルユニット21が弁ハウジング11側の円筒部(プラグ部材17+プランジャチューブ16)に抜け止め固定される。   As described above, the intermediate portions 35 and 36 of the locking wire 31 are engaged with the tapered surface (inclined surface) 45A in the elastically deformed state in the radial direction, so that the electromagnetic coil unit does not include radial backlash. 21 is secured to the cylindrical portion (plug member 17 + plunger tube 16) on the valve housing 11 side.

これと同時に、係止線材31が弾性変形によるばね荷重によって傾斜面であるテーパ面(溝面)45Aに押し付けられることにより、ガイド部材17の軸線方向分力(頭部148Aを上方へ持ち上げる方向の力)が、円筒部(プラグ部材17+プランジャチューブ16)と電磁コイルユニット21との間に発生する。この軸線方向分力によって、プラグ部材17の円柱部41と回転止め部43との段差部分に設けられている端面44が、上片22Bの下端面37に押し付けられる。これにより、電磁コイルユニット21が軸線方向のがた付きを含むことなく円筒部(プラグ部材17+プランジャチューブ16)に固定される。   At the same time, the locking wire 31 is pressed against the tapered surface (groove surface) 45A, which is an inclined surface, by a spring load due to elastic deformation, whereby the axial force component of the guide member 17 (in the direction of lifting the head portion 148A upward). Force) is generated between the cylindrical portion (plug member 17 + plunger tube 16) and the electromagnetic coil unit 21. By this axial force component, the end surface 44 provided at the step portion between the cylindrical portion 41 and the rotation stopper 43 of the plug member 17 is pressed against the lower end surface 37 of the upper piece 22B. As a result, the electromagnetic coil unit 21 is fixed to the cylindrical portion (plug member 17 + plunger tube 16) without including any backlash in the axial direction.

さらには、これと同時に、回転止め形状の挿入孔28と回転止め部43との整合係合によって電磁コイルユニット21の回転止めも行われる。   Furthermore, at the same time, the rotation of the electromagnetic coil unit 21 is also stopped by the alignment engagement between the rotation-preventing insertion hole 28 and the rotation stopper 43.

図24、図25は、この発明による電磁コイル取付構造のさらにもう一つの実施形態を示している。なお、図24、図25においても、図1〜図8に対応する部分は、図1〜図8に付した符号と同一の符号を付けて、その説明を省略する。   24 and 25 show still another embodiment of the electromagnetic coil mounting structure according to the present invention. 24 and 25, portions corresponding to those in FIGS. 1 to 8 are denoted by the same reference numerals as those in FIGS. 1 to 8, and description thereof is omitted.

この実施形態でも、電磁コイルユニット21の上片22Bに平行2面取り部27による小判形の挿入孔28と同じ小判形が形成され、この小判形の挿入孔28の長辺(平行2面取り部27)に沿って係止線材31の中間部35、36が配置されている。なお、係止線材31の上片22Bに対する取り付けは、図示していないが、上述の実施形態と同様に行われる。   Also in this embodiment, the same oval shape as the oval insertion hole 28 formed by the parallel two-chamfered portion 27 is formed on the upper piece 22B of the electromagnetic coil unit 21, and the long side (the parallel two-chamfered portion 27) of the oval-shaped insertion hole 28 is formed. ) Are disposed along the intermediate portions 35 and 36 of the locking wire 31. The attachment to the upper piece 22B of the locking wire 31 is not shown, but is performed in the same manner as in the above embodiment.

プラグ部材17の頭部248が平行2面取り部63によって挿入孔28と同じ小判形に形成されている。頭部248、すなわち小判形形状部分の形状、寸法は、挿入孔28の形状及び寸法とほぼ同じで、頭部248が挿入孔28を貫通可能になっている。頭部248と円柱部41との間に、平行2面取り部63の幅寸法より少し小さい外径の中間円柱部64が形成されている。頭部248と挿入孔28は小判形に代えて長方形でもよい。   The head 248 of the plug member 17 is formed in the same oval shape as the insertion hole 28 by the parallel two chamfered portion 63. The shape and size of the head portion 248, that is, the oval shape portion are substantially the same as the shape and size of the insertion hole 28, and the head portion 248 can penetrate the insertion hole 28. Between the head portion 248 and the cylindrical portion 41, an intermediate cylindrical portion 64 having an outer diameter slightly smaller than the width dimension of the parallel two-chamfered portion 63 is formed. The head 248 and the insertion hole 28 may be rectangular instead of the oval shape.

中間円柱部64の外周のうち、頭部248の長辺(平行2面取り部63)と直交する方向の2箇所(両側)に係合溝65が形成されている。係合溝65は、前述の実施形態の係合溝46と同等のものであり、傾斜溝底面66を有する。なお、係合溝65は中間円柱部64の全周に設けられていてもよく、その底面66は、傾斜溝でなく中間円柱部64の軸方向に沿って傾斜を有しない平面であってもよい。   Engaging grooves 65 are formed at two locations (both sides) in a direction orthogonal to the long side (parallel two chamfered portion 63) of the head 248 in the outer periphery of the intermediate cylindrical portion 64. The engagement groove 65 is equivalent to the engagement groove 46 of the above-described embodiment, and has an inclined groove bottom surface 66. Note that the engagement groove 65 may be provided on the entire circumference of the intermediate cylindrical portion 64, and the bottom surface 66 may be a flat surface that does not have an inclination along the axial direction of the intermediate cylindrical portion 64 instead of the inclined groove. Good.

この実施形態では、挿入孔28の平行2面取り部27の位置と頭部248の平行2面取り部63の位置とがプラグ部材17の周方向において一致するようにした状態で、電磁コイルユニット21を、下側から円筒部(プラグ部材17+プランジャチューブ16)の外周に嵌装する。   In this embodiment, the electromagnetic coil unit 21 is placed in a state in which the position of the parallel two chamfered portion 27 of the insertion hole 28 and the position of the parallel two chamfered portion 63 of the head portion 248 coincide with each other in the circumferential direction of the plug member 17. The cylinder portion (plug member 17 + plunger tube 16) is fitted to the outer periphery from below.

頭部248が挿入孔28を通過した段階で、電磁コイルユニット21を円筒部(プラグ部材17+プランジャチューブ16)に対して中心軸線周りに90度回転させる。これにより、両側の係合溝65の各々に係止線材31の中間部35、36が径方向に弾性変形した状態で嵌り込み係合する。   When the head 248 passes through the insertion hole 28, the electromagnetic coil unit 21 is rotated 90 degrees around the central axis with respect to the cylindrical portion (plug member 17 + plunger tube 16). Accordingly, the intermediate portions 35 and 36 of the locking wire 31 are fitted and engaged with the engagement grooves 65 on both sides in a state of being elastically deformed in the radial direction.

この実施形態でも、係止線材31の中間部35、36が係合溝65に径方向の弾性変形状態で係合することにより、径方向のがた付きを含むことなく、電磁コイルユニット21が弁ハウジング11側の円筒部(プラグ部材17+プランジャチューブ16)に抜け止め固定される。   Even in this embodiment, the intermediate portions 35 and 36 of the locking wire 31 are engaged with the engaging groove 65 in the elastically deformed state in the radial direction, so that the electromagnetic coil unit 21 has no radial backlash. It is secured to the cylindrical portion (plug member 17 + plunger tube 16) on the valve housing 11 side.

これと同時に、係止線材31が弾性変形によるばね荷重によって傾斜溝底面66に押し付けられることにより、ガイド部材17の軸線方向分力(頭部248を上方へ持ち上げる方向の力)が、円筒部(プラグ部材17+プランジャチューブ16)と電磁コイルユニット21との間に発生する。この軸線方向分力によって、プラグ部材17の円柱部41と回転止め部43との段差部分に設けられている端面44が、上片22Bの下端面37に押し付けられる。これにより、電磁コイルユニット21が軸線方向のがた付きを含むことなく円筒部(プラグ部材17+プランジャチューブ16)に固定される。また、この固定状態では、頭部248と挿入孔28とが相互に90度回転変位しているから、確実な抜け止めが行われる。   At the same time, the locking wire 31 is pressed against the inclined groove bottom surface 66 by a spring load due to elastic deformation, whereby the axial component of the guide member 17 (the force in the direction of lifting the head 248 upward) is applied to the cylindrical portion ( It occurs between the plug member 17 + plunger tube 16) and the electromagnetic coil unit 21. By this axial force component, the end surface 44 provided at the step portion between the cylindrical portion 41 and the rotation stopper 43 of the plug member 17 is pressed against the lower end surface 37 of the upper piece 22B. As a result, the electromagnetic coil unit 21 is fixed to the cylindrical portion (plug member 17 + plunger tube 16) without including any backlash in the axial direction. Further, in this fixed state, the head 248 and the insertion hole 28 are rotationally displaced by 90 degrees with each other, so that reliable securing is performed.

図26、図27は、この発明による電磁コイル取付構造のもう一つの実施形態を示している。この実施形態では、係止線材31が外凾22の下片22Aの下面に取り付けられ、係合溝46がプランジャチューブ16の下端側(弁ハウジング11側)に設けられた構造になっている。   26 and 27 show another embodiment of the electromagnetic coil mounting structure according to the present invention. In this embodiment, the locking wire 31 is attached to the lower surface of the lower piece 22A of the outer casing 22, and the engaging groove 46 is provided on the lower end side (valve housing 11 side) of the plunger tube 16.

この場合には、図27に示されているように、外凾22の下片22Aには丸穴67が明けられ、外凾22の上片22Bに設けられる挿入孔28の平行2面取り部27の位置と丸穴67の周りにある係止線材31の中間部35、36の位置とがガイド部材17の周方向において90度位相ずれしている場合を示している。   In this case, as shown in FIG. 27, a round hole 67 is formed in the lower piece 22 </ b> A of the outer casing 22, and a parallel two chamfered portion 27 of the insertion hole 28 provided in the upper piece 22 </ b> B of the outer casing 22. And the positions of the intermediate portions 35 and 36 of the locking wire 31 around the round hole 67 are 90 degrees out of phase in the circumferential direction of the guide member 17.

この実施形態では、プラグ部材17の先端側の回転止め部43の平行2面取り部42を係止線材31の中間部35、36の間隔方向に合わせた状態で、円筒部(プラグ部材17+プランジャチューブ16)の外周への電磁コイルユニット21の嵌装、つまり、円筒部(プラグ部材17+プランジャチューブ16)の挿入孔24への挿入を開始する。   In this embodiment, the cylindrical portion (plug member 17 + plunger tube) in a state where the parallel two chamfered portions 42 of the rotation stopper 43 on the distal end side of the plug member 17 are aligned with the interval direction of the intermediate portions 35, 36 of the locking wire 31. 16) The mounting of the electromagnetic coil unit 21 on the outer periphery, that is, the insertion of the cylindrical portion (plug member 17 + plunger tube 16) into the insertion hole 24 is started.

そして、回転止め部43の2面取り部42が中間部35、36間に入った段階で、電磁コイルユニット21を回転させる。これにより、回転止め部43の平行2面取り部42に当接していた係止線材31の中間部35、36が回転止め部43の周面43Aに乗り上げて押し広げられる。これよりさらに、円筒部(プラグ部材17+プランジャチューブ16)を丸穴67に挿入し、挿入孔28の平行2面取り部27の位置と回転止め部43の平行2面取り部42の位置とがガイド部材17の周方向において一致するように回転させ、回転止め部43を挿入孔28に挿入係合させる。そして、プラグ部材17に設けられている平行2面取り部42の端面42Aが上片22Bの下面に当接した時点で、挿入嵌合が完了し、係止線材31の中間部35、36が係合溝46に係合する。   Then, the electromagnetic coil unit 21 is rotated at the stage where the two chamfered portions 42 of the rotation stopping portion 43 enter between the intermediate portions 35 and 36. As a result, the intermediate portions 35 and 36 of the locking wire 31 that have been in contact with the parallel two chamfered portions 42 of the rotation stopping portion 43 ride on the circumferential surface 43A of the rotation stopping portion 43 and are spread. Further, the cylindrical portion (plug member 17 + plunger tube 16) is inserted into the round hole 67, and the position of the parallel two chamfered portion 27 of the insertion hole 28 and the position of the parallel two chamfered portion 42 of the rotation stopper 43 are guide members. The rotation stoppers 43 are rotated so as to coincide with each other in the circumferential direction, and the rotation stoppers 43 are inserted and engaged with the insertion holes 28. When the end face 42A of the parallel two chamfered portion 42 provided on the plug member 17 comes into contact with the lower surface of the upper piece 22B, the insertion fitting is completed, and the intermediate portions 35 and 36 of the locking wire 31 are engaged. Engage with the mating groove 46.

これにより、この実施形態でも、上述した実施形態と同等の作用、効果が得られる。   Thereby, also in this embodiment, the same operation and effect as the above-described embodiment can be obtained.

ちなみに、図26、図27の実施形態において、図27に示されているように、丸穴67の周りにある係止線材31の中間部35、36の位置に対してプラグ部材17の周方向において90度位相ずれさせている、外凾22の上片22Bに設けられる挿入孔28の平行2面取り部27を、係止線材31の中間部35、36の位置と合致して両者に位相ずれの無い位置に形成し、プラグ部材17に平行2面取り部42を形成することによってプラグ部材17と回転止め部43との段差部分に発生する端面42Aを、傾斜面またはR面としてもよい。   Incidentally, in the embodiment of FIGS. 26 and 27, as shown in FIG. 27, the circumferential direction of the plug member 17 with respect to the positions of the intermediate portions 35 and 36 of the locking wire 31 around the round hole 67. The two parallel chamfered portions 27 of the insertion hole 28 provided in the upper piece 22B of the outer casing 22 are shifted in phase by 90 degrees at the same position as the intermediate portions 35 and 36 of the locking wire 31 and shifted in phase to each other. The end surface 42A generated at the step portion between the plug member 17 and the rotation stopper 43 by forming the parallel chamfered portion 42 on the plug member 17 may be an inclined surface or an R surface.

その場合には、電磁コイルユニット21を途中で回転させなくても、円筒部(プラグ部材17+プランジャチューブ16)を丸孔67に単に挿入し続けることで、係止線材31の中間部35、36が平行2面取り部42に当接しながらこれに乗り上げて、プラグ部材17の直径と同じ間隔となるまで押し広げられるので、さらに円筒部(プラグ部材17+プランジャチューブ16)を丸孔67に挿入すると、プラグ部材17に設けられている平行2面取り部42の端面42Aが上片22Bの下面に当接した時点で、回転止め部43が挿入孔28に挿入係合することになる。   In that case, the intermediate portions 35 and 36 of the locking wire 31 can be obtained by simply inserting the cylindrical portion (plug member 17 + plunger tube 16) into the round hole 67 without rotating the electromagnetic coil unit 21 halfway. Rides on the parallel two-chamfered portion 42 and pushes it up to the same distance as the diameter of the plug member 17, so that when the cylindrical portion (plug member 17 + plunger tube 16) is further inserted into the round hole 67, When the end face 42A of the parallel chamfer 42 provided on the plug member 17 comes into contact with the lower surface of the upper piece 22B, the rotation stopper 43 is inserted into and engaged with the insertion hole 28.

図28、図29は、この発明による電磁コイル取付構造のもう一つの実施形態を示している。   28 and 29 show another embodiment of the electromagnetic coil mounting structure according to the present invention.

この実施形態でも、電磁コイルユニット21の上片22Bには平行2面取り部27による小判形の挿入孔28の小判形が形成されている。この小判形の挿入孔28の長辺(平行2面取り部27)に沿って係止線材31の中間部35、36が配置されている。中間部35、36の配置位置は、図示されているように、平行2面取り部27の縁部より外側になっている。なお、係止線材31の上片22Bに対する取り付けは、図示していないが、上述の実施形態と同様に行われる。   Also in this embodiment, an oval shape of an oval insertion hole 28 is formed in the upper piece 22B of the electromagnetic coil unit 21 by a parallel two-chamfered portion 27. Intermediate portions 35 and 36 of the locking wire 31 are disposed along the long side (parallel two chamfered portion 27) of the oval insertion hole 28. The arrangement positions of the intermediate portions 35 and 36 are outside the edge of the parallel two-chamfered portion 27 as shown in the figure. The attachment to the upper piece 22B of the locking wire 31 is not shown, but is performed in the same manner as in the above embodiment.

プラグ部材17の頭部348が平行2面取り部68によって挿入孔28と同じ小判形に形成されている。頭部348、すなわち小判形形状部分の形状、寸法は、挿入孔28の形状及び寸法とほぼ同じで、頭部348が挿入孔28を貫通可能になっている。頭部348と円柱部41との間に、平行2面取り部68の幅寸法より少し小さい外径の中間円柱部69が形成されている。頭部348の長辺(平行2面取り部68)と直交する側の両側面がV形の傾斜面70になっている。なお、頭部348と挿入孔28は小判形に代えて長方形でもよい。   The head portion 348 of the plug member 17 is formed in the same oval shape as the insertion hole 28 by the parallel two chamfered portions 68. The shape and size of the head portion 348, that is, the oval shape portion are substantially the same as the shape and size of the insertion hole 28, and the head portion 348 can penetrate the insertion hole 28. Between the head portion 348 and the cylindrical portion 41, an intermediate cylindrical portion 69 having an outer diameter slightly smaller than the width dimension of the parallel two-chamfered portion 68 is formed. Both side surfaces of the head 348 on the side orthogonal to the long side (parallel two chamfered portions 68) are V-shaped inclined surfaces 70. The head 348 and the insertion hole 28 may be rectangular instead of the oval shape.

この実施形態では、挿入孔28の平行2面取り部27の位置と頭部348の平行2面取り部68の位置とがプラグ部材17の周方向において一致するようにした状態で、電磁コイルユニット21を、下側から円筒部(プラグ部材17+プランジャチューブ16)の外周に嵌装する。   In this embodiment, the electromagnetic coil unit 21 is placed in a state in which the position of the parallel two chamfered portion 27 of the insertion hole 28 and the position of the parallel two chamfered portion 68 of the head 348 coincide with each other in the circumferential direction of the plug member 17. The cylinder portion (plug member 17 + plunger tube 16) is fitted to the outer periphery from below.

頭部348が挿入孔28を通過した段階で、電磁コイルユニット21を円筒部(プラグ部材17+プランジャチューブ16)に対して中心軸線周りに90度回転させる。これにより、頭部348の両側の傾斜面70の各々に係止線材31の中間部35、36が径方向に弾性変形した状態で係合する。   When the head 348 passes through the insertion hole 28, the electromagnetic coil unit 21 is rotated 90 degrees around the central axis with respect to the cylindrical portion (plug member 17 + plunger tube 16). Accordingly, the intermediate portions 35 and 36 of the locking wire 31 are engaged with the inclined surfaces 70 on both sides of the head 348 in a state of being elastically deformed in the radial direction.

この実施形態では、係止線材31の中間部35、36が傾斜面70に径方向の弾性変形状態で係合することにより、径方向のがた付きを含むことなく、電磁コイルユニット21が弁ハウジング11側の円筒部(プラグ部材17+プランジャチューブ16)に抜け止め固定される。   In this embodiment, the intermediate portions 35 and 36 of the locking wire 31 are engaged with the inclined surface 70 in an elastically deformed state in the radial direction, so that the electromagnetic coil unit 21 has the valve without including radial backlash. It is fixed to the cylindrical portion (plug member 17 + plunger tube 16) on the housing 11 side to prevent it from coming off.

これと同時に、係止線材31が弾性変形によるばね荷重によって傾斜面70に押し付けられることにより、ガイド部材17の軸線方向分力(頭部348を上方へ持ち上げる方向の力)が、円筒部(プラグ部材17+プランジャチューブ16)と電磁コイルユニット21との間に発生する。この軸線方向分力によって、プラグ部材17の円柱部41と回転止め部43との段差部分に設けられている端面44が、上片22Bの下端面37に押し付けられる。これにより、電磁コイルユニット21が軸線方向のがた付きを含むことなく円筒部(プラグ部材17+プランジャチューブ16)に固定される。また、この固定状態では、頭部348と挿入孔28とが相互に90度回転変位しているから、確実な抜け止めが行われる。   At the same time, when the locking wire 31 is pressed against the inclined surface 70 by the spring load due to elastic deformation, the axial component of the guide member 17 (the force in the direction of lifting the head 348 upward) is applied to the cylindrical portion (plug It occurs between the member 17 + plunger tube 16) and the electromagnetic coil unit 21. By this axial force component, the end surface 44 provided at the step portion between the cylindrical portion 41 and the rotation stopper 43 of the plug member 17 is pressed against the lower end surface 37 of the upper piece 22B. As a result, the electromagnetic coil unit 21 is fixed to the cylindrical portion (plug member 17 + plunger tube 16) without including any backlash in the axial direction. Further, in this fixed state, the head 348 and the insertion hole 28 are rotated and displaced by 90 degrees with respect to each other, so that reliable securing is performed.

ちなみに、図28、図29の実施形態では、元々円柱形状であった部材を回転させつつ切削して傾斜面70を形成していることから、傾斜面70が曲面状となっているが、円柱形状であった部材の両側を切り落として各平行2面取り部68を先に形成し、続いて、各平行2面取り部68のプランジャチューブ16側の部分や、両平行2面取り部68間を接続する頭部348の一対の側面のうちプランジャチューブ16側の部分を、傾斜状に切り落とすことで、各傾斜面70を、両傾斜面70間を接続する面と同様に、平坦面としてもよい。   Incidentally, in the embodiment of FIGS. 28 and 29, since the inclined surface 70 is formed by cutting while rotating the originally cylindrical member, the inclined surface 70 has a curved surface. Both parallel chamfered portions 68 are first formed by cutting off both sides of the shaped member, and subsequently, the portion of each parallel two chamfered portion 68 on the plunger tube 16 side and the two parallel chamfered portions 68 are connected.
