The valve seal 36 is formed in a substantially annular shape with, for example, resin, and has a seal opening 360 inside. The valve seal 36 is provided so that one surface thereof is in contact with the outer peripheral wall of the valve body 31, and can be liquid-tightly maintained between the valve seal 36 and the outer peripheral wall of the valve body 31.
　スリーブ３７１は、例えば金属により筒状に形成され、一端でバルブシール３６を保持している。スリーブ３７１の他端は、パイプ部５１１の一端の内側に位置している。スプリング３７２は、スリーブ３７１の一端とパイプ部５１１の一端との間に設けられ、スリーブ３７１とともにバルブシール３６を弁体３１側へ付勢している。シール部材３７３は、例えばゴムにより環状に形成され、パイプ部５１１の一端とスリーブ３７１の外周壁との間に設けられ、パイプ部５１１とスリーブ３７１との間を液密に保持可能である。 The sleeve 371 is formed in a cylindrical shape from, for example, metal, and holds the valve seal 36 at one end. The other end of the sleeve 371 is located inside one end of the pipe portion 511. The spring 372 is provided between one end of the sleeve 371 and one end of the pipe portion 511, and urges the valve seal 36 together with the sleeve 371 toward the valve body 31. The seal member 373 is formed in an annular shape by rubber, for example, is provided between one end of the pipe portion 511 and the outer peripheral wall of the sleeve 371, and can hold the space between the pipe portion 511 and the sleeve 371 in a liquid-tight manner.
　出口ポート２２２、２２３に設けられたシールユニット３５も、出口ポート２２１に設けられたシールユニット３５と同様の構成のため、説明を省略する。３つのシールユニット３５は、それぞれ、パイプ部５１１、５１２、５１３の一端に組み付けられている。 Since the seal units 35 provided at the outlet ports 222 and 223 are configured in the same manner as the seal unit 35 provided at the outlet port 221, description thereof will be omitted. The three seal units 35 are assembled to one ends of the pipe portions 511, 512, and 513, respectively.
　隔壁部６０は、例えば樹脂により形成されている。隔壁部６０は、ハウジング本体２１とは別体に形成されている。隔壁部６０は、隔壁部本体６１等を有している。隔壁部本体６１は、略円板状に形成されている。隔壁部６０は、隔壁部本体６１がハウジング開口部２１０を塞ぐようハウジング本体２１に設けられている。隔壁部６０は、隔壁部本体６１の中央を板厚方向に貫くシャフト挿通穴６２を有している。バルブ３０は、シャフト３２の一端がシャフト挿通穴６２を挿通するようにして設けられている。シャフト３２は、一端が隔壁部本体６１により軸受けされ、他端がハウジング本体２１により軸受けされている。 The partition wall 60 is made of, for example, resin. The partition wall 60 is formed separately from the housing body 21. The partition wall 60 has a partition wall body 61 and the like. The partition wall body 61 is formed in a substantially disk shape. The partition wall 60 is provided in the housing body 21 so that the partition wall body 61 closes the housing opening 210. The partition wall 60 has a shaft insertion hole 62 that penetrates the center of the partition wall body 61 in the thickness direction. The valve 30 is provided such that one end of the shaft 32 is inserted through the shaft insertion hole 62. One end of the shaft 32 is supported by the partition wall body 61 and the other end is supported by the housing body 21.
　駆動部カバー８０は、隔壁部６０に対し内部空間２００とは反対側に設けられ、隔壁部６０との間に駆動部空間８００を形成している。 The drive unit cover 80 is provided on the side opposite to the internal space 200 with respect to the partition wall 60, and forms a drive space 800 between the partition wall 60.
　駆動部７０は、駆動部空間８００に設けられ、シャフト３２の一端を経由して弁体３１を回転駆動可能である。駆動部７０は、モータ７１、ギア部７２等を有している。ギア部７２は、シャフト３２の一端に接続している。ＥＣＵ８がモータ７１への供給電力を制御すると、モータ７１の駆動力は、ギア部７２を経由してシャフト３２に伝達する。これにより、弁体３１が回転駆動する。 The drive unit 70 is provided in the drive unit space 800 and can rotate the valve body 31 via one end of the shaft 32. The drive unit 70 includes a motor 71, a gear unit 72, and the like. The gear part 72 is connected to one end of the shaft 32. When the ECU 8 controls the power supplied to the motor 71, the driving force of the motor 71 is transmitted to the shaft 32 via the gear portion 72. Thereby, the valve body 31 is rotationally driven.
　図５に示すように、リリーフポート２２４には、リリーフ弁３９が設けられている。リリーフ弁３９は、所定の条件、例えば冷却水の温度が所定の温度以上となったとき、開弁し、リリーフポート２２４を経由した内部空間２００とハウジング本体２１の外部すなわちパイプ部５１５の内側の空間との連通を許容し、冷却水の温度が所定の温度より低くなったとき、上記連通を遮断する。 As shown in FIG. 5, the relief port 224 is provided with a relief valve 39. The relief valve 39 is opened when a predetermined condition, for example, when the temperature of the cooling water is equal to or higher than a predetermined temperature, and is opened outside the internal space 200 and the housing body 21 via the relief port 224, that is, inside the pipe portion 515. The communication with the space is allowed, and when the temperature of the cooling water becomes lower than a predetermined temperature, the communication is cut off.
　図３、図６に示すように、隔壁部６０は、隔壁部本体６１の内部空間２００側の面から駆動部７０側へ凹むＣ字状の規制凹部６３が形成されている。規制凹部６３の周方向の端部間には、規制部６３１が形成されている。図３、図６に示すように、弁体３１には、駆動部７０側の端面から規制凹部６３側へ延びて先端部が規制凹部６３内に位置する第１規制凸部３３２、第２規制凸部３４２が形成されている。そのため、弁体３１は、第１規制凸部３３２が規制部６３１に当接したとき、および、第２規制凸部３４２が規制部６３１に当接したとき、その回転が規制される。つまり、弁体３１は、第１規制凸部３３２が規制部６３１に当接する位置から第２規制凸部３４２が規制部６３１に当接する位置までの範囲で回転可能である。 3 and 6, the partition wall 60 is formed with a C-shaped regulating recess 63 that is recessed from the surface of the partition wall body 61 on the inner space 200 side to the drive unit 70 side. A regulating portion 631 is formed between the circumferential ends of the regulating recess 63. As shown in FIGS. 3 and 6, the valve body 31 includes a first restriction convex portion 332 that extends from the end surface on the drive portion 70 side to the restriction concave portion 63 and has a tip portion located in the restriction concave portion 63. A convex portion 342 is formed. Therefore, the rotation of the valve body 31 is restricted when the first restriction convex part 332 comes into contact with the restriction part 631 and when the second restriction convex part 342 comes into contact with the restriction part 631. That is, the valve body 31 is rotatable in a range from a position where the first restriction convex part 332 contacts the restriction part 631 to a position where the second restriction convex part 342 contacts the restriction part 631.
　バルブ装置１０は、入口ポート２２０がウォータージャケット３の出口に接続するようエンジン２に取り付けられる。そのため、入口ポート２２０から内部空間２００に流入した冷却水は、バルブ間空間４００を経由して弁体内流路３００に流入する。また、弁体３１の回転により、弁体開口部４３０、４２０、４１０とそれぞれのシール開口部３６０とが重なったとき、その重なり面積に応じて冷却水が弁体内流路３００から弁体開口部４３０、４２０、４１０を経由してデバイス７、ヒータ６、ラジエータ５へ流れる。 The valve device 10 is attached to the engine 2 so that the inlet port 220 is connected to the outlet of the water jacket 3. Therefore, the cooling water that has flowed into the internal space 200 from the inlet port 220 flows into the valve body flow path 300 via the inter-valve space 400. Further, when the valve body openings 430, 420, 410 and the respective seal openings 360 are overlapped by the rotation of the valve body 31, the cooling water flows from the valve body flow path 300 to the valve body opening according to the overlapping area. It flows to the device 7, the heater 6, and the radiator 5 through 430, 420, and 410.
　ＥＣＵ８は、モータ７１の作動を制御し、弁体３１の回転位置を制御することにより、デバイス７に冷却水を流し、デバイス７において熱交換できるため、エンジンオイルやＥＧＲガスを冷却して燃費を向上できる。また、ヒータ６に冷却水を流し、車両１内の空気と冷却水との間で熱交換できるため、車両１内を暖めることができる。 The ECU 8 controls the operation of the motor 71 and controls the rotational position of the valve body 31 so that cooling water can flow through the device 7 and heat exchange can be performed in the device 7. Therefore, the engine oil and EGR gas are cooled to improve fuel efficiency. It can be improved. Moreover, since cooling water can be flowed through the heater 6 and heat can be exchanged between the air in the vehicle 1 and the cooling water, the inside of the vehicle 1 can be warmed.
　図７は、弁体３１の回転位置（横軸）と、弁体開口部４３０、４２０、４１０の開閉状態（縦軸）、すなわち、弁体開口部４３０、４２０、４１０とそれぞれのシール開口部３６０との重なり面積との関係を示す図である。ここで、弁体開口部４３０、４２０、４１０とそれぞれのシール開口部３６０との重なり面積は、デバイス７、ヒータ６、ラジエータ５への冷却水の流路面積に対応している。 7 shows the rotational position (horizontal axis) of the valve body 31 and the open / closed state (vertical axis) of the valve body openings 430, 420, 410, that is, the valve body openings 430, 420, 410 and the respective seal openings. It is a figure which shows the relationship with 360 and an overlapping area. Here, the overlapping area of the valve body openings 430, 420, 410 and the respective seal openings 360 corresponds to the flow path area of the cooling water to the device 7, the heater 6, and the radiator 5.
　ＥＣＵ８は、ヒータ６に冷却水を流す要求（ヒータ要求）がある場合に使用される「通常モード」と、ヒータ要求がない場合に使用される「ヒータカットモード」とを選択し、弁体３１を回転させる。「通常モード」と「ヒータカットモード」とは、全ての弁体開口部４３０、４２０、４１０が弁体３１の外周壁により閉じられて（全閉状態：図３参照）、デバイス７、ヒータ６、ラジエータ５への冷却水の流量がゼロとなる領域（領域ｄ）を隔てている。領域ｄでは、デバイス７、ヒータ６、ラジエータ５への冷却水の流れは遮断されている。 The ECU 8 selects a “normal mode” used when there is a request to flow cooling water through the heater 6 (heater request) and a “heater cut mode” used when there is no heater request, and the valve body 31. Rotate. In the “normal mode” and the “heater cut mode”, all the valve body openings 430, 420, and 410 are closed by the outer peripheral wall of the valve body 31 (fully closed state: see FIG. 3). A region (region d) where the flow rate of the cooling water to the radiator 5 is zero is separated. In the region d, the flow of cooling water to the device 7, the heater 6, and the radiator 5 is blocked.
　「通常モード」では、ヒータ６への通水が最優先される。図７において、領域ｄから右に進む方向に弁体３１を回転させると、弁体３１の回転位置が領域ｄの隣の領域（領域ｃ）に移行する。領域ｃでは弁体開口部４２０が開き始め、ヒータ６に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４２０が完全に開き、弁体３１の回転位置が領域ｃの隣の領域（領域ｂ）に移行する。領域ｂでは弁体開口部４３０が開き始め、デバイス７に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４３０が完全に開き、弁体３１の回転位置が領域ｂの隣の領域（領域ａ）に移行する。領域ａでは弁体開口部４１０が開き始め、ラジエータ５に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４１０が完全に開く（全開状態）。なお、弁体開口部４１０が完全に開かれる弁体３１の回転位置が弁体３１の回転限界（Ｒｏｔａｔｉｏｎ　ｌｉｍｉｔ）に相当し、このとき、第１規制凸部３３２は規制部６３１に当接している（図６参照）。 In the “normal mode”, the water flow to the heater 6 has the highest priority. In FIG. 7, when the valve body 31 is rotated in the direction proceeding to the right from the region d, the rotational position of the valve body 31 is shifted to a region (region c) adjacent to the region d. In the area c, the valve element opening 420 starts to open, and the cooling water starts to flow into the heater 6. When the valve body 31 is further rotated, the valve body opening 420 is completely opened, and the rotational position of the valve body 31 is shifted to a region (region b) adjacent to the region c. In the region b, the valve body opening 430 starts to open, and the cooling water starts to flow into the device 7. When the valve body 31 is further rotated, the valve body opening 430 is completely opened, and the rotational position of the valve body 31 shifts to a region (region a) adjacent to the region b. In the region a, the valve body opening 410 starts to open, and the cooling water starts to flow into the radiator 5. When the valve body 31 is further rotated, the valve body opening 410 is completely opened (fully opened state). Note that the rotational position of the valve body 31 at which the valve body opening 410 is completely opened corresponds to the rotation limit of the valve body 31, and at this time, the first restriction convex part 332 is in contact with the restriction part 631. (See FIG. 6).
　「ヒータカットモード」では、ヒータ６への通水は行われず、ラジエータ５よりもデバイス７への通水が優先される。図７において、領域ｄから左に進む方向に弁体３１を回転させると、領域ｄの隣の領域（領域ｅ）に移行する。領域ｅでは弁体開口部４３０が開き始め、デバイス７に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４３０が完全に開き、弁体３１の回転位置が領域ｅの隣の領域（領域ｆ）に移行する。領域ｆでは弁体開口部４３０のみが開き、デバイス７にのみ冷却水が流れる。さらに弁体３１を回転させると、弁体３１の回転位置が領域ｆの隣の領域（領域ｇ）に移行する。領域ｇでは弁体開口部４１０が開き始め、ラジエータ５に冷却水が流れ始める。さらに弁体３１を回転させると、弁体開口部４１０が完全に開く。ＥＣＵ８は、図７に示す「通常モード」と「ヒータカットモード」とに基づき弁体３１を回転駆動することにより、燃費と空調性能の両立を図ることが可能である。 In the “heater cut mode”, water is not passed to the heater 6, but water is given priority to the device 7 over the radiator 5. In FIG. 7, when the valve body 31 is rotated in a direction that proceeds to the left from the region d, the region shifts to a region adjacent to the region d (region e). In the region e, the valve body opening 430 starts to open, and the cooling water starts to flow into the device 7. When the valve body 31 is further rotated, the valve body opening 430 is completely opened, and the rotational position of the valve body 31 is shifted to a region (region f) adjacent to the region e. In the region f, only the valve body opening 430 is opened, and the cooling water flows only to the device 7. When the valve body 31 is further rotated, the rotational position of the valve body 31 shifts to a region (region g) adjacent to the region f. In the region g, the valve body opening 410 starts to open, and the cooling water starts to flow into the radiator 5. When the valve body 31 is further rotated, the valve body opening 410 is completely opened. The ECU 8 can achieve both fuel efficiency and air conditioning performance by rotationally driving the valve body 31 based on the “normal mode” and the “heater cut mode” shown in FIG.
　図２に示すように、エンジン２には、インテークマニホールド１１、オルタネータ１２、ウォーターポンプ４、コンプレッサ１３、スタータ１４、トランスミッション１５等が組付けられている。バルブ装置１０は、オルタネータ１２とインテークマニホールド１１との間の狭小空間Ａ１においてエンジン２に取り付けられる。ここで、バルブ装置１０は、駆動部７０側が鉛直方向下側を向くようにしてエンジン２に取り付けられる。そのため、内部空間２００等で発生したベーパ等の空気は、鉛直方向上側へ移動し、パイプ部５１６を経由してリザーバタンクに排出される。 As shown in FIG. 2, the engine 2 is assembled with an intake manifold 11, an alternator 12, a water pump 4, a compressor 13, a starter 14, a transmission 15, and the like. The valve device 10 is attached to the engine 2 in a narrow space A1 between the alternator 12 and the intake manifold 11. Here, the valve device 10 is attached to the engine 2 such that the drive unit 70 side faces downward in the vertical direction. Therefore, air such as vapor generated in the internal space 200 or the like moves upward in the vertical direction and is discharged to the reservoir tank via the pipe portion 516.

　図８、図９、図１０に示すように、ハウジング２０は、ハウジング本体２１と一体に形成された締結部２３１、２３２、２３３を有している。締結部２３１、２３２、２３３は、ハウジング本体２１の取付面２０１側の端部から取付面２０１の面方向に突出するよう形成されている。また、ハウジング２０は、締結部２３１、２３２、２３３のそれぞれに対応して形成された締結穴２４１、２４２、２４３を有している。ここで、締結穴２４１、２４２、２４３は、それぞれ、「第１締結穴」、「第２締結穴」、「第３締結穴」に対応している。 <1-2>
As shown in FIGS. 8, 9, and 10, the housing 20 includes fastening portions 231, 232, and 233 that are formed integrally with the housing body 21. The fastening portions 231, 232, and 233 are formed so as to protrude in the surface direction of the mounting surface 201 from the end of the housing body 21 on the mounting surface 201 side. The housing 20 has fastening holes 241, 242, 243 formed corresponding to the fastening portions 231, 232, 233, respectively. Here, the fastening holes 241, 242, and 243 correspond to a “first fastening hole”, a “second fastening hole”, and a “third fastening hole”, respectively.
　締結穴２４１、２４２、２４３には、締結部材２４０が挿通され、エンジン２に締結される。これにより、バルブ装置１０がエンジン２に取り付けられる。取付面２０１の入口ポート２２０の径方向外側には、環状ゴム製のポートシール部材２０９が設けられる。ポートシール部材２０９は、バルブ装置１０がエンジン２に取り付けられた状態において、締結部材２４０の軸力により圧縮された状態となる。これにより、ポートシール部材２０９は、取付面２０１とエンジン２との間を液密に保持し、入口ポート２２０から取付面２０１とエンジン２との間を経由して冷却水が漏れるのを抑制できる。 The fastening member 240 is inserted into the fastening holes 241, 242, and 243 and fastened to the engine 2. Thereby, the valve device 10 is attached to the engine 2. An annular rubber port seal member 209 is provided on the outer side in the radial direction of the inlet port 220 of the mounting surface 201. The port seal member 209 is compressed by the axial force of the fastening member 240 when the valve device 10 is attached to the engine 2. As a result, the port seal member 209 can keep the mounting surface 201 and the engine 2 in a liquid-tight state, and can prevent the coolant from leaking from the inlet port 220 through the mounting surface 201 and the engine 2. .
　図９、図１０に示すように、締結穴２４１は、取付面２０１における入口ポート２２０の開口の径方向外側に形成されている。締結穴２４２は、締結穴２４１との間に入口ポート２２０の開口を挟むようにして形成されている。締結穴２４３は、締結穴２４１、２４２に対し駆動部７０側に形成されている。 As shown in FIGS. 9 and 10, the fastening hole 241 is formed on the radially outer side of the opening of the inlet port 220 in the mounting surface 201. The fastening hole 242 is formed so as to sandwich the opening of the inlet port 220 between the fastening hole 241. The fastening hole 243 is formed on the drive unit 70 side with respect to the fastening holes 241 and 242.

A shaft 32.
　隔壁部６０は、内部空間２００とハウジング本体２１の外部とを隔てる。 The partition wall 60 separates the internal space 200 from the outside of the housing body 21.
　駆動部７０は、隔壁部６０に対し内部空間２００とは反対側に設けられ、シャフト３２を経由して弁体３１を回転駆動可能である。 The drive unit 70 is provided on the side opposite to the internal space 200 with respect to the partition wall unit 60, and can rotate the valve body 31 via the shaft 32.

　締結穴は、入口ポート２２０の開口の径方向外側に形成された第１締結穴（２４１）、第１締結穴との間に入口ポート２２０の開口を挟むよう形成された第２締結穴（２４２）、および、第１締結穴および第２締結穴に対し駆動部７０側に形成された第３締結穴（２４３）を含む。 The fastening holes are a first fastening hole (241) formed radially outside the opening of the inlet port 220, and a second fastening hole (242) formed so as to sandwich the opening of the inlet port 220 between the first fastening hole. ), And a third fastening hole (243) formed on the drive unit 70 side with respect to the first fastening hole and the second fastening hole.

Thereby, the sealing performance around the inlet port 220 can be effectively secured.
　また、締結穴２４３を通る締結部材２４０により締結部２３３がエンジン２に固定されることにより、エンジン２の振動の駆動部７０への影響を抑制することができる。 Further, the fastening portion 233 is fixed to the engine 2 by the fastening member 240 passing through the fastening hole 243, so that the influence of the vibration of the engine 2 on the driving portion 70 can be suppressed.

　締結穴２４３と駆動部７０との距離は、締結穴２４３と入口ポート２２０の開口の中心Ｃｐ１との距離より短い。 <1-2-3>
The distance between the fastening hole 243 and the drive unit 70 is shorter than the distance between the fastening hole 243 and the center Cp1 of the opening of the inlet port 220.

The valve device 10 further includes a fixing member 830 capable of fixing the housing main body 21 and the driving unit cover 80 in a state where the partition wall 60 is sandwiched between the housing main body 21 and the driving unit cover 80.
　そのため、隔壁部６０の位置が安定し、弁体３１の軸精度を向上できる。 Therefore, the position of the partition wall 60 is stabilized, and the axial accuracy of the valve body 31 can be improved.
　また、隔壁部６０および駆動部カバー８０をハウジング本体２１に一度に組み付けでき、組付けを簡素化できる。また、固定部材の数を低減できる。 Also, the partition wall 60 and the drive unit cover 80 can be assembled to the housing body 21 at a time, and the assembly can be simplified. Moreover, the number of fixing members can be reduced.
　固定部材８３０は、例えばねじであり、駆動部カバー８０に形成されたカバー締結穴８３１を通り、ハウジング本体２１の締結穴に螺合する。これにより、駆動部カバー８０は、ハウジング本体２１との間に隔壁部６０を挟んだ状態でハウジング本体２１に固定される。なお、カバー締結穴は、駆動部カバー８０に複数形成され、それぞれに固定部材８３０が挿通されている。なお、駆動部カバー８０の外縁部と隔壁部６０との間には、ゴム製環状のカバーシール部材８０９が設けられている。これにより、駆動部空間８００は気密液密に保持されている。 The fixing member 830 is, for example, a screw, passes through the cover fastening hole 831 formed in the drive unit cover 80, and is screwed into the fastening hole of the housing main body 21. Thus, the drive unit cover 80 is fixed to the housing body 21 with the partition wall 60 sandwiched between the drive body cover 80 and the housing body 21. A plurality of cover fastening holes are formed in the drive unit cover 80, and the fixing member 830 is inserted through each of them.

As shown in FIG. 11, the partition wall 60 has a shaft insertion hole 62 through which one end of the shaft 32 can be inserted. The valve device 10 includes a metal ring 601 that is insert-molded in the partition wall 60 in the shaft insertion hole 62. The metal ring 601 is formed of a metal in an annular shape and is provided coaxially with the shaft insertion hole 62. The valve device 10 is provided inside the metal ring 601 and includes a bearing portion 602 that supports one end of the shaft 32. The bearing portion 602 is a ball bearing, for example, and is press-fitted inside the metal ring 601.
　そのため、樹脂（隔壁部６０）と金属（軸受部６０２）との線膨張差や樹脂劣化により、軸受部６０２が保持できなくなるのを抑制でき、シャフト３２の軸受け精度を維持できる。 Therefore, it is possible to prevent the bearing portion 602 from being held due to a difference in linear expansion between the resin (partition wall portion 60) and the metal (bearing portion 602) or the resin deterioration, and the bearing accuracy of the shaft 32 can be maintained.

Here, the surface 609 is a planar part formed on the same plane as the end surface of the metal ring 601 on the drive unit cover 80 side on the drive unit cover 80 side of the partition wall 60.
　そのため、隔壁部６０の一体成型時のヒケや反り、軸受部６０２の圧入による変形を抑制できる。これにより、隔壁部６０の外周部分の寸法精度を向上でき、弁体３１の軸精度を向上できる。 Therefore, sink marks and warpage during integral molding of the partition wall portion 60 and deformation due to press-fitting of the bearing portion 602 can be suppressed. Thereby, the dimensional accuracy of the outer peripheral part of the partition part 60 can be improved, and the axial precision of the valve body 31 can be improved.

　図２４、図２５に示すように、弁体開口リブ４１１は、弁体３１のボールバルブ４１の外周壁に沿う仮想球面Ｖｓ１から径方向内側へ離れた位置に形成されている。 24 and 25, the valve body opening rib 411 is formed at a position away from the virtual spherical surface Vs1 along the outer peripheral wall of the ball valve 41 of the valve body 31 inward in the radial direction.
　そのため、弁体３１の回転時、バルブシール３６が弁体開口リブ４１１に引っ掛かり摺動抵抗が増大するのを抑制できる。 Therefore, when the valve body 31 is rotated, it is possible to suppress the valve seal 36 from being caught by the valve body opening rib 411 and increasing the sliding resistance.
＜３－９－１＞
　図２４、図２５に示すように、弁体開口リブ４１１は、仮想球面Ｖｓ１から所定の距離を空けて円弧状に形成されている。なお、弁体開口リブ４２１、４２２、および、弁体開口リブ４３１、４３２についても、ボールバルブ４２、４３の外周壁に沿う仮想球面から所定の距離を空けて円弧状に形成されている。 <3-9-1>
As shown in FIGS. 24 and 25, the valve body opening rib 411 is formed in an arc shape with a predetermined distance from the phantom spherical surface Vs1. The valve body opening ribs 421 and 422 and the valve body opening ribs 431 and 432 are also formed in an arc shape with a predetermined distance from a virtual spherical surface along the outer peripheral wall of the ball valves 42 and 43.
　そのため、弁体３１の回転時の摺動抵抗の増大を抑制できるとともに、弁体開口リブ４１１、４２１、４２２、４３１、４３２の内側の流路面積を大きくできる。 Therefore, an increase in sliding resistance during rotation of the valve body 31 can be suppressed, and the flow path area inside the valve body opening ribs 411, 421, 422, 431, and 432 can be increased.

　図２６に示すように、接合面３３１、３４１は、全てのバルブシール３６のシール開口部３６０の全てが弁体３１の外周壁で塞がれた全閉状態のとき、バルブシール３６から離れた位置にある。 <3-11>
As shown in FIG. 26, the joint surfaces 331 and 341 are separated from the valve seal 36 when all the seal openings 360 of all the valve seals 36 are closed by the outer peripheral wall of the valve body 31. In position.
　そのため、弁体３１の接合面３３１、３４１において外周壁に形成され得る段差により、弁体３１が全閉状態のとき、バルブシール３６と弁体３１の外周壁との間から冷却水が漏れるのを抑制できる。 Therefore, cooling water leaks between the valve seal 36 and the outer peripheral wall of the valve body 31 when the valve body 31 is in the fully closed state due to the steps that can be formed on the outer peripheral wall at the joint surfaces 331 and 341 of the valve body 31. Can be suppressed.

　図２０に示すように、弁体３１は、筒状接続部４４において接合面３３１、３４１上に形成され筒状接続部４４の外周壁の曲率と曲率が異なる外壁を有する特定形状部４４１を有している。弁体３１は、筒状バルブ接続部４５において接合面３３１、３４１上に形成され筒状バルブ接続部４５の外周壁の曲率と曲率が異なる外壁を有する特定形状部４５１を有している。 <3-12>
As shown in FIG. 20, the valve body 31 has a specific shape portion 441 that is formed on the joint surfaces 331 and 341 in the cylindrical connection portion 44 and has an outer wall having a curvature different from the curvature of the outer peripheral wall of the cylindrical connection portion 44. is doing. The valve body 31 has a specific shape portion 451 having an outer wall that is formed on the joint surfaces 331 and 341 in the tubular valve connection portion 45 and has a curvature different from the curvature of the outer peripheral wall of the tubular valve connection portion 45.
　そのため、弁体３１の回転時、特定形状部４４１、４５１とバルブシール３６とが摺動することはなく、弁体３１の作動不良を抑制できるとともに、バルブシール３６の摩耗を抑制できる。 Therefore, when the valve body 31 rotates, the specific shape portions 441 and 451 and the valve seal 36 do not slide, so that the malfunction of the valve body 31 can be suppressed and the wear of the valve seal 36 can be suppressed.

　特定形状部４４１、４５１は、それぞれ、外壁が筒状接続部４４、筒状バルブ接続部４５の外周壁から外側へ突出するよう形成されている。 <3-12-1>

　図２２に示すように、弁体３１は、筒状接続部４４の径方向外側においてボールバルブ４１とボールバルブ４２との間に形成されるバルブ間空間４００とボールバルブ４１の弁体内流路３００とを接続するようボールバルブ４１の回転軸Ａｘｒ１方向の端面に形成された端面開口部４１５、および、バルブ間空間４００とボールバルブ４２の弁体内流路３００とを接続するようボールバルブ４２の回転軸Ａｘｒ１方向の端面に形成された端面開口部４２５を有している。ここで、端面開口部４１５、４２５は、それぞれ、「第１端面開口部」、「第２端面開口部」に対応している。 <3-13>
As shown in FIG. 22, the valve body 31 includes an inter-valve space 400 formed between the ball valve 41 and the ball valve 42 on the radially outer side of the cylindrical connection portion 44 and a valve body flow path 300 of the ball valve 41. Of the ball valve 42 so as to connect the end surface opening 415 formed on the end surface of the ball valve 41 in the direction of the rotation axis Axr1 and the inter-valve space 400 and the valve body flow passage 300 of the ball valve 42. It has an end face opening 425 formed on the end face in the direction of the axis Axr1. Here, the end surface openings 415 and 425 correspond to a “first end surface opening” and a “second end surface opening”, respectively.
　入口ポート２２０は（図３参照）、バルブ間空間４００に連通している。そのため、入口ポート２２０から内部空間２００に流入した冷却水は、バルブ間空間４００、端面開口部４１５、４２５を経由して弁体内流路３００に流入可能である。 The inlet port 220 (see FIG. 3) communicates with the inter-valve space 400. Therefore, the cooling water flowing into the internal space 200 from the inlet port 220 can flow into the valve body flow path 300 via the inter-valve space 400 and the end surface openings 415 and 425.
　バルブ間空間４００は、周方向の全域にわたって開口している。そのため、入口ポート２２０から内部空間２００に流入し弁体内流路３００に向かう冷却水の通水抵抗を小さくできる。 The inter-valve space 400 is open over the entire circumferential direction. Therefore, the flow resistance of the cooling water flowing from the inlet port 220 into the internal space 200 and flowing toward the valve body flow path 300 can be reduced.

　図２７に示すように、シャフト３２は、筒状接続部４４においてインサート成型により弁体３１と一体に形成されている。つまり、シャフト３２は、筒状接続部４４には溶着されているが、弁体３１の筒状接続部４４以外の部位には溶着されていない。 <3-14>
As shown in FIG. 27, the shaft 32 is formed integrally with the valve body 31 by insert molding at the cylindrical connecting portion 44. That is, the shaft 32 is welded to the cylindrical connection portion 44, but is not welded to a portion other than the cylindrical connection portion 44 of the valve body 31.
　弁体内流路３００にシャフト３２とのインサート成型部を設けた場合、弁体内流路３００の流路面積が小さくなり通水抵抗が大きくなるおそれがあるが、本実施形態では、弁体内流路３００の外の筒状接続部４４にシャフト３２とのインサート成型部が設けられているため、通水抵抗を小さくできる。 When an insert molding portion with the shaft 32 is provided in the valve body flow path 300, the flow path area of the valve body flow path 300 may be reduced and the water flow resistance may be increased. Since the insert molding part with the shaft 32 is provided in the cylindrical connection part 44 outside 300, the water flow resistance can be reduced.
＜３－１５＞
　図２７に示すように、シャフト３２は、筒状接続部４４との相対回転を規制可能な回り止め部３２１を有している。回り止め部３２１は、断面形状が多角形となるよう形成されている。本実施形態では、断面形状が六角形となるよう形成されている。ここで、回り止め部３２１は、例えば円柱状のシャフト３２の外周壁を周方向に６箇所、平面状に切削等することにより形成されている。そのため、回り止め部３２１の外壁は、シャフト３２の外周壁に対し径方向内側に位置している。なお、筒状接続部４４の内壁は、回り止め部３２１の形状に対応するよう断面形状が六角形となるよう形成されている。 <3-15>
As shown in FIG. 27, the shaft 32 has a detent portion 321 that can restrict relative rotation with the cylindrical connection portion 44. The anti-rotation part 321 is formed so that the cross-sectional shape is a polygon. In this embodiment, the cross-sectional shape is a hexagon. Here, the rotation prevention part 321 is formed, for example, by cutting the outer peripheral wall of the columnar shaft 32 into a flat shape at six places in the circumferential direction. Therefore, the outer wall of the rotation preventing portion 321 is located on the radially inner side with respect to the outer peripheral wall of the shaft 32. Note that the inner wall of the cylindrical connection portion 44 is formed to have a hexagonal cross section so as to correspond to the shape of the rotation preventing portion 321.
　そのため、簡単な構成で、弁体３１とシャフト３２との相対回転を規制できる。 Therefore, the relative rotation between the valve body 31 and the shaft 32 can be restricted with a simple configuration.

　図２８に示すように、弁体３１は、ボールバルブ４２に対し筒状接続部４４とは反対側においてボールバルブ４２に接続し外周壁および内周壁が筒状に形成され内側に弁体内流路３００を形成する筒状バルブ接続部４５、および、筒状バルブ接続部４５に対しボールバルブ４２とは反対側において筒状バルブ接続部４５に接続し外周壁が球面状に形成されたボールバルブ４３を有している。 <3-16>
As shown in FIG. 28, the valve body 31 is connected to the ball valve 42 on the side opposite to the cylindrical connecting portion 44 with respect to the ball valve 42, and the outer peripheral wall and the inner peripheral wall are formed in a cylindrical shape, and the valve body flow path is formed inside. A cylindrical valve connecting portion 45 that forms 300, and a ball valve 43 that is connected to the cylindrical valve connecting portion 45 on the opposite side of the cylindrical valve connecting portion 45 from the ball valve 42 and whose outer peripheral wall is formed in a spherical shape. have.
　筒状バルブ接続部４５は、外周壁および内周壁が筒状に形成されている。そのため、内側の弁体内流路３００の流路面積を確保できる。 The cylindrical valve connecting portion 45 has an outer peripheral wall and an inner peripheral wall formed in a cylindrical shape. Therefore, the flow path area of the inner valve body flow path 300 can be secured.

　図２０に示すように、ボールバルブ４１の外周壁の外径は、ボールバルブ４３の外周壁の外径と同じである。なお、ボールバルブ４２の外周壁の外径も、ボールバルブ４１の外周壁の外径、ボールバルブ４３の外周壁の外径と同じである。 <3-17>
As shown in FIG. 20, the outer diameter of the outer peripheral wall of the ball valve 41 is the same as the outer diameter of the outer peripheral wall of the ball valve 43. The outer diameter of the outer peripheral wall of the ball valve 42 is also the same as the outer diameter of the outer peripheral wall of the ball valve 41 and the outer diameter of the outer peripheral wall of the ball valve 43.
　ボールバルブ４１の回転軸Ａｘｒ１方向のボールバルブ４３とは反対側の端面である第１最外端面３０１の面積は、ボールバルブ４３の回転軸Ａｘｒ１方向のボールバルブ４１とは反対側の端面である第２最外端面３０２の面積と異なる。ここで、第２最外端面３０２の面積は、第１最外端面３０１の面積より大きい。よって、回転軸Ａｘｒ１方向におけるボールバルブ４３の長さは、ボールバルブ４１の長さより短い。 The area of the first outermost end surface 301 that is the end surface of the ball valve 41 opposite to the ball valve 43 in the direction of the rotation axis Axr1 is the end surface of the ball valve 43 opposite to the ball valve 41 in the direction of the rotation axis Axr1. It is different from the area of the second outermost end surface 302. Here, the area of the second outermost end surface 302 is larger than the area of the first outermost end surface 301. Therefore, the length of the ball valve 43 in the direction of the rotation axis Axr1 is shorter than the length of the ball valve 41.
　そのため、弁体３１の軸方向の大きさを小さくでき、バルブ装置１０の体格を小さくできる。 Therefore, the size of the valve body 31 in the axial direction can be reduced, and the physique of the valve device 10 can be reduced.

As shown in FIGS. 20 and 22, the valve body 31 includes a valve body opening rib 422 connecting the inner edge of the valve body opening 420 of the ball valve 42 and an inner edge of the valve body opening 430 of the ball valve 43. The valve body opening rib 432 is connected. Here, the valve body opening rib 422 and the valve body opening rib 432 correspond to a “second valve body opening rib” and a “third valve body opening rib”, respectively.
　弁体開口リブ４２２と弁体開口リブ４３２とは、弁体３１の周方向において同じ位置に形成されている。つまり、弁体開口リブ４２２、４３２は、回転軸Ａｘｒ１と平行な方向に並ぶよう形成されている。なお、弁体開口リブ４１１と弁体開口リブ４２１とは、弁体３１の周方向において同じ位置に形成されている。 The valve element opening rib 422 and the valve element opening rib 432 are formed at the same position in the circumferential direction of the valve element 31. That is, the valve body opening ribs 422 and 432 are formed to be aligned in a direction parallel to the rotation axis Axr1. The valve body opening rib 411 and the valve body opening rib 421 are formed at the same position in the circumferential direction of the valve body 31.
　そのため、弁体開口リブ４２２、４３２の周囲を流れる冷却水の乱れを抑制でき、通水抵抗を低減できる。 Therefore, the disturbance of the cooling water flowing around the valve body opening ribs 422 and 432 can be suppressed, and the water flow resistance can be reduced.

Two end face opening ribs 417 and 427 are formed so that the cylindrical connecting portion 44 is sandwiched therebetween.
　なお、端面開口リブ４１６、４２６は、仮想平面Ｖｐ１上に形成されている。つまり、端面開口リブ４１６、４２６は、接合面３３１、３４１を挟むようにして形成されている。よって、弁体開口リブ４１１、４２１、および、端面開口リブ４１６、４２６は、弁体３１の周方向において同じ位置に形成されている。 Note that the end face opening ribs 416 and 426 are formed on the virtual plane Vp1. That is, the end surface opening ribs 416 and 426 are formed so as to sandwich the bonding surfaces 331 and 341.

In addition, the distance between the second concave surface 123 and the second convex surface 171 is the same.
　そのため、弁体３１の少なくとも一部を均肉にすることができる。これにより、弁体３１の外周壁の球面の精度をより向上でき、弁体内流路３００の流路面積をより大きくできる。 Therefore, at least a part of the valve body 31 can be made uniform. Thereby, the precision of the spherical surface of the outer peripheral wall of the valve body 31 can be further improved, and the flow passage area of the flow passage 300 can be increased.

　１次成形工程の後のスライド工程では、第１分割体３３と第２分割体３４とのそれぞれの接合面３３１、３４１が対向するよう、第１分割体３３または第２分割体３４を第１型１１０または第２型１２０ごとスライドさせる。具体的には、図２９の（Ｂ）に示すように、第１内型１１２を第１外型１１１から外し、第２内型１２２を第２外型１２１から外し、第１分割体３３と第２分割体３４とのそれぞれの接合面３３１、３４１が対向するよう、第１分割体３３を第１外型１１１ごとスライドさせる。 <3-23>
(Slide process)
In the slide process after the primary forming process, the first divided body 33 or the second divided body 34 is moved to the first divided body 33 or the second divided body 34 so that the joint surfaces 331 and 341 of the first divided body 33 and the second divided body 34 face each other. Slide the mold 110 or the second mold 120 together. Specifically, as shown in FIG. 29B, the first inner mold 112 is removed from the first outer mold 111, the second inner mold 122 is removed from the second outer mold 121, and the first divided body 33 and The first divided body 33 is slid together with the first outer mold 111 so that the respective joint surfaces 331 and 341 with the second divided body 34 face each other.

(Shaft placement process)
In the shaft arrangement step after the sliding step, the shaft 32 is arranged on the rotation axis Axr1 of the valve body 31. Specifically, as illustrated in FIG. 29C, the shaft 32 is disposed on the rotation axis Axr1 between the first divided body 33 and the second divided body 34.
　そのため、弁体３１成型後にシャフト３２を組み付ける場合と比べ、シャフト３２の組付け工数等を低減できる。 Therefore, compared with the case where the shaft 32 is assembled after the valve body 31 is molded, the number of steps for assembling the shaft 32 can be reduced.

　シャフト配置工程の後の２次成形工程では、第１分割体３３の接合面における溶着部と第２分割体３４の接合面における溶着部との間に樹脂を射出し、第１分割体３３と第２分割体３４とを溶着する。 <3-22>

Resin that has flowed into the welded portions 311, 312, and 313 from the gate inlets 141, 142, and 143 flows toward the gate outlets 145, 146, and 147, and flows out from the gate outlets 145, 146, and 147, respectively. When the resin in the welded parts 311, 312, and 313 is cooled and hardened, the first divided body 33, the second divided body 34, and the shaft 32 are welded, and the secondary molding process is completed. Here, the resin remaining at positions corresponding to the gate inlet 142 and the gate outlet 146 of the cylindrical connection portion 44 of the valve body 31 forms a specific shape portion 441.

As described above, the present embodiment is a method for manufacturing the valve 30 having the valve body 31 rotatable around the rotation axis Axr1 and the valve body flow passage 300 formed inside the valve body 31. A next forming step and a second forming step are included.
　弁体３１は、外周壁の少なくとも一部が球面状に形成され、内周壁の少なくとも一部が外側へ凹むよう形成され、回転軸Ａｘｒ１を含む仮想平面Ｖｐ１で２つに分割された第１分割体３３と第２分割体３４とを有し、第１分割体３３と第２分割体３４とがそれぞれの接合面３３１、３４１で接合される。 The valve body 31 has a first division in which at least a part of the outer peripheral wall is formed into a spherical shape, and at least a part of the inner peripheral wall is formed to be recessed outward, and is divided into two on a virtual plane Vp1 including the rotation axis Axr1. It has the body 33 and the 2nd division body 34, and the 1st division body 33 and the 2nd division body 34 are joined by each joint surface 331,341.
　１次成形工程では、第１分割体３３と第２分割体３４とをそれぞれ第１型１１０と第２型１２０とにより樹脂成形する。 In the primary molding step, the first divided body 33 and the second divided body 34 are resin-molded by the first mold 110 and the second mold 120, respectively.
　第２成形工程では、第１分割体３３の接合面３３１における溶着部（３１１、３１２、３１３）と第２分割体３４の接合面３４１における溶着部（３１１、３１２、３１３）との間に樹脂を射出し、第１分割体３３と第２分割体３４とを溶着する。 In the second molding step, a resin is formed between the welded portions (311, 312, 313) on the joint surface 331 of the first divided body 33 and the welded portions (311, 312, 313) on the joint surface 341 of the second divided body 34. The first divided body 33 and the second divided body 34 are welded.
　上記製造方法でバルブ３０を製造することにより、弁体３１の外周壁の球面の成形精度を向上できる。これにより、弁体３１の外周壁における冷却水の漏れを抑制可能である。 By manufacturing the valve 30 by the above manufacturing method, the molding accuracy of the spherical surface of the outer peripheral wall of the valve body 31 can be improved. Thereby, the leakage of the cooling water in the outer peripheral wall of the valve body 31 can be suppressed.
　また、弁体内流路３００の流路面積を大きくでき、通水抵抗を小さくできる。 Moreover, the flow passage area of the valve body flow passage 300 can be increased, and the water flow resistance can be reduced.
　　（第４実施形態）
　第４実施形態によるバルブ装置の一部を図３３に示す。 (Fourth embodiment)
A part of the valve device according to the fourth embodiment is shown in FIG.
＜３－１０＞
　図３３に示すように、弁体開口リブ４１１は、仮想球面Ｖｓ１から所定の距離を空けて直線状に形成されている。なお、弁体開口リブ４２１、４２２、および、弁体開口リブ４３１、４３２についても、ボールバルブ４２、４３の外周壁に沿う仮想球面から所定の距離を空けて直線状に形成されている。 <3-10>
As shown in FIG. 33, the valve body opening rib 411 is formed in a straight line with a predetermined distance from the phantom spherical surface Vs1. The valve body opening ribs 421 and 422 and the valve body opening ribs 431 and 432 are also formed in a straight line with a predetermined distance from a virtual spherical surface along the outer peripheral wall of the ball valves 42 and 43.
　そのため、弁体３１の回転時、バルブシール３６が弁体開口リブ４１１に引っ掛かり摺動抵抗が増大するのをより効果的に抑制できる。 Therefore, when the valve body 31 rotates, it is possible to more effectively suppress the valve seal 36 from being caught by the valve body opening rib 411 and increasing the sliding resistance.
　　（第５実施形態）
　第５実施形態によるバルブ装置の一部を図３４に示す。 (Fifth embodiment)

The shaft 32 is provided on the rotation axis Axr1 of the valve body 31. The ball valve 46 has an outer peripheral wall 461 and an inner peripheral wall 462. The outer peripheral wall 461 is formed in a spherical shape so as to swell outward in the radial direction of the ball valve 46. The inner peripheral wall 462 is formed in a spherical shape so as to be recessed outward in the radial direction of the ball valve 46. Here, the valve body 31 has the same distance between the outer peripheral wall 461 and the inner peripheral wall 462 in at least a partial range in the direction of the rotation axis Axr1 and the circumferential direction. That is, the valve body 31 is formed so that the thickness is uniform (equal thickness) at least in the above range.
　次に、バルブ３０の製造方法について説明する。 Next, a method for manufacturing the valve 30 will be described.
　図３５に示すように、型装置１５０は、上ベース１５１、下ベース１５２、上支持柱１５３、下支持柱１５４、型駆動体１５５、第１内側型１６０、第２内側型１７０、外側型１８０等を備えている。 As shown in FIG. 35, the mold apparatus 150 includes an upper base 151, a lower base 152, an upper support pillar 153, a lower support pillar 154, a mold driver 155, a first inner mold 160, a second inner mold 170, and an outer mold 180. Etc.
　上ベース１５１は、板状に形成されている。下ベース１５２は、板状に形成され、上ベース１５１に対し平行となるよう設けられている。上支持柱１５３は、棒状に形成され、一端が上ベース１５１の下ベース１５２とは反対側に接続している。上支持柱１５３は、一端が上ベース１５１において型装置１５０の中心軸ＣＡｘ１周りに環状をなすよう８本設けられている（図３６参照）。上支持柱１５３は、一端を支点として他端側が中心軸ＣＡｘ１側へ揺動可能である。 The upper base 151 is formed in a plate shape. The lower base 152 is formed in a plate shape and is provided so as to be parallel to the upper base 151. The upper support pillar 153 is formed in a rod shape, and one end thereof is connected to the side opposite to the lower base 152 of the upper base 151. Eight upper support columns 153 are provided so that one end of the upper support column 153 has an annular shape around the central axis CAx1 of the mold apparatus 150 in the upper base 151 (see FIG. 36). The upper support column 153 can swing toward the central axis CAx1 at the other end with one end as a fulcrum.
　下支持柱１５４は、棒状に形成され、一端が下ベース１５２の上ベース１５１側に接続している。下支持柱１５４は、他端が上ベース１５１の穴を通り上ベース１５１に対し下ベース１５２とは反対側に位置するよう設けられている。下支持柱１５４は、一端が下ベース１５２において中心軸ＣＡｘ１周りに環状をなすよう８本設けられている（図３７参照）。下支持柱１５４は、一端を支点として他端側が中心軸ＣＡｘ１側へ揺動可能である。 The lower support pillar 154 is formed in a rod shape, and one end thereof is connected to the upper base 151 side of the lower base 152. The lower support column 154 is provided so that the other end passes through the hole of the upper base 151 and is located on the opposite side of the lower base 152 with respect to the upper base 151. Eight lower support pillars 154 are provided so that one end forms a ring around the central axis CAx1 in the lower base 152 (see FIG. 37). The lower support column 154 is swingable toward the central axis CAx1 at the other end with one end as a fulcrum.
　第１内側型１６０は、８本の上支持柱１５３のそれぞれの他端に設けられている。すなわち、第１内側型１６０は、合計８個設けられている。第２内側型１７０は、８本の下支持柱１５４のそれぞれの他端に設けられている。すなわち、第２内側型１７０は、合計８個設けられている。 The first inner mold 160 is provided at the other end of each of the eight upper support columns 153. That is, a total of eight first inner molds 160 are provided. The second inner mold 170 is provided at the other end of each of the eight lower support columns 154. That is, a total of eight second inner molds 170 are provided.
　図３８に示すように、第１内側型１６０は、外壁の一部に第１凸面１６１を有している。第１凸面１６１は、球面状に形成されている。第２内側型１７０は、外壁の一部に第２凸面１７１を有している。第２凸面１７１は、球面状に形成されている。 38, the first inner mold 160 has a first convex surface 161 on a part of the outer wall. The first convex surface 161 is formed in a spherical shape. The second inner mold 170 has a second convex surface 171 on a part of the outer wall. The second convex surface 171 is formed in a spherical shape.
　図３５に示すように、第１内側型１６０と第２内側型１７０とは、第１凸面１６１、第２凸面１７１が中心軸ＣＡｘ１とは反対側を向くよう周方向に交互に配置されている。これにより、第１凸面１６１と第２凸面１７１とは、周方向に連続する球面を形成可能である。 As shown in FIG. 35, the first inner mold 160 and the second inner mold 170 are alternately arranged in the circumferential direction so that the first convex surface 161 and the second convex surface 171 face the side opposite to the central axis CAx1. . Thereby, the 1st convex surface 161 and the 2nd convex surface 171 can form the spherical surface continuous in the circumferential direction.
　外側型１８０は、内壁に凹面１８１を有している（図３９参照）。凹面１８１は、球面状に形成されている。外側型１８０は、凹面１８１が第１凸面１６１および第２凸面１７１に対向するよう第１内側型１６０および第２内側型１７０の外側に配置される。 The outer mold 180 has a concave surface 181 on the inner wall (see FIG. 39). The concave surface 181 is formed in a spherical shape. The outer mold 180 is disposed outside the first inner mold 160 and the second inner mold 170 so that the concave surface 181 faces the first convex surface 161 and the second convex surface 171.
　型駆動体１５５は、筒状に形成されている。型駆動体１５５は、中心軸ＣＡｘ１と同軸に第１内側型１６０および第２内側型１７０の内側に配置される。型駆動体１５５の外周壁には、係合溝部１５６が形成されている。係合溝部１５６は、型駆動体１５５の一端から他端へ延びるよう形成されている。係合溝部１５６は、型駆動体１５５の周方向に等間隔で８つ形成されている。 The mold driver 155 is formed in a cylindrical shape. The mold driver 155 is disposed inside the first inner mold 160 and the second inner mold 170 coaxially with the central axis CAx1. An engagement groove 156 is formed on the outer peripheral wall of the mold driver 155. The engaging groove 156 is formed so as to extend from one end to the other end of the mold driver 155. Eight engaging groove portions 156 are formed at equal intervals in the circumferential direction of the mold driver 155.
　第１内側型１６０は、第１凸面１６１とは反対側に係合凸部１６２を有している。係合凸部１６２は、型駆動体１５５の係合溝部１５６に係合可能である。また、型駆動体１５５は、係合溝部１５６に係合凸部１６２が係合した状態で、中心軸ＣＡｘ１方向に移動可能である。型駆動体１５５の外周壁は、テーパ状に形成されている。そのため、型駆動体１５５が第１内側型１６０および第２内側型１７０に対し中心軸ＣＡｘ１方向の上ベース１５１側へ相対移動すると、８個の第１内側型１６０は、中心軸ＣＡｘ１側へ集まるようにして移動する（図３９、図４０参照）。これにより、第１凸面１６１で形成される球状の面の内径が縮小する。なお、第１内側型１６０が中心軸ＣＡｘ１側へ集まるようにして移動すると、８個の第２内側型１７０も中心軸ＣＡｘ１側へ集まるようにして移動可能である。すなわち、第１内側型１６０と第２内側型１７０とが中心軸ＣＡｘ１側へ集まるようにして移動すると、第１凸面１６１および第２凸面１７１で形成される球状の面の内径が縮小する。 The first inner mold 160 has an engaging convex portion 162 on the side opposite to the first convex surface 161. The engaging convex portion 162 can be engaged with the engaging groove portion 156 of the mold driver 155. The mold driver 155 is movable in the direction of the central axis CAx1 in a state in which the engagement protrusion 162 is engaged with the engagement groove 156. The outer peripheral wall of the mold driver 155 is formed in a tapered shape. Therefore, when the mold driver 155 moves relative to the first inner mold 160 and the second inner mold 170 toward the upper base 151 in the direction of the central axis CAx1, the eight first inner molds 160 gather toward the central axis CAx1. In this way, it moves (see FIGS. 39 and 40). As a result, the inner diameter of the spherical surface formed by the first convex surface 161 is reduced. When the first inner mold 160 moves so as to gather toward the central axis CAx1, the eight second inner molds 170 can also move so as to gather toward the central axis CAx1. That is, when the first inner mold 160 and the second inner mold 170 move so as to gather toward the central axis CAx1, the inner diameter of the spherical surface formed by the first convex surface 161 and the second convex surface 171 is reduced.

(Resin molding process)
In the resin molding step, the valve body 31 is resin-molded between the outer mold 180 and the first inner mold 160 and the second inner mold 170 disposed inside the outer mold 180. Specifically, as shown in FIGS. 35 and 39A, a space formed between the spherical surface formed by the first convex surface 161 and the second convex surface 171 and the concave surface 181 of the outer die 180. Then, the molten resin is injected. When the resin cools and hardens, the resin molding process is completed.

When the valve body 31 is resin-molded in the resin molding step, the distance between the concave surface 181 and the first convex surface 161 and the second convex surface 171 is the same in at least a part of the rotational axis Axr1 direction and the circumferential direction (FIG. 39). (See (A)).
　そのため、弁体３１の少なくとも一部を均肉にすることができる。これにより、弁体３１の外周壁の球面の精度をより向上でき、弁体内流路３００の流路面積をより大きくできる。 Therefore, at least a part of the valve body 31 can be made uniform.

In the mold moving process after the resin molding process, the first inner mold 160 and the second inner mold 170 are moved to the inside of the valve body 31. Specifically, as shown in FIGS. 39A and 39B and FIGS. 40A to 40E, the mold driver 155 is centered with respect to the first inner mold 160 and the second inner mold 170. The first inner mold 160 and the second inner mold 170 are moved relative to each other in the direction of the axis CAx1, and the first inner mold 160 and the second inner mold 170 are moved toward the central axis CAx1, thereby reducing the diameter of the spherical surface formed by the first convex surface 161 and the second convex surface 171. Thereby, a gap is formed between the inner peripheral wall 462 of the valve body 31 and the first and second convex surfaces 161 and 171. Then, the first inner mold 160 and the second inner mold 170 are extracted from the valve body 31 by moving the first inner mold 160 and the second inner mold 170 relative to the valve body 31 in the direction of the central axis CAx1.

　そのため、第１内側型１６０および第２内側型１７０を弁体３１内から抜き出すとき、第１凸面１６１および第２凸面１７１が弁体３１の内周壁４６２に干渉することなく、第１内側型１６０および第２内側型１７０を弁体３１から容易に抜き出すことができる。 Therefore, when the first inner mold 160 and the second inner mold 170 are extracted from the valve body 31, the first convex surface 161 and the second convex surface 171 do not interfere with the inner peripheral wall 462 of the valve body 31, and the first inner mold 160 And the 2nd inner side type | mold 170 can be easily extracted from the valve body 31.
