The hook portion 52 and the elastic claw portion 53 function as a first attachment portion for attaching the lower portion of the base member 22, and the locking claw portion 54 and the overhang portion 58 are second attachment portions for attaching the upper portion of the base member 22. Function as.
　ロック装置１０の外側部材１２への取付工程について説明する。ベース部材２２は、操作部材２０を軸支した状態で外側部材１２の裏側から取付口１２ａに取り付けられる。作業者は、外側部材１２の裏側から操作部材２０の操作部３６を取付口１２ａに挿入し、フック部５２を取付縁部１２ｈに引っ掛け、位置決めする。フック部５２を引っかけるとともに、一対の弾性爪部５３は、撓んで取付縁部１２ｈを乗り越え、復元して取付縁部１２ｈの係止する。 The attachment process to the outer member 12 of the locking device 10 will be described. The base member 22 is attached to the attachment port 12a from the back side of the outer member 12 with the operation member 20 being pivotally supported. The operator inserts the operation portion 36 of the operation member 20 into the attachment port 12a from the back side of the outer member 12, and hooks the hook portion 52 to the attachment edge portion 12h to position it. While hooking the hook portion 52, the pair of elastic claws 53 bend and get over the mounting edge portion 12h to restore and lock the mounting edge portion 12h.
　次に、作業者は、フック部５２を支点としてベース部材２２を回転させて、一対の係止爪部５４を係合孔１２ｇの縁に押し込み、一対の係止爪部５４を撓ませる。一対の係止爪部５４は、取付壁部１２ｉを通過して係合孔１２ｇ内に入ると復元力により係合孔１２ｇの縁に係止して、ベース部材２２が外側部材１２の取付口１２ａに取り付けられる。 Next, the operator rotates the base member 22 with the hook portion 52 as a fulcrum, pushes the pair of locking claws 54 into the edges of the engagement holes 12g, and bends the pair of locking claws 54. When the pair of locking claws 54 pass through the mounting wall 12i and enter the engaging hole 12g, the base member 22 is locked to the edge of the engaging hole 12g by a restoring force, and the base member 22 is attached to the mounting hole of the outer member 12. 12a.
　このように、ネジ等で固定する場合と比べて、フック部５２を引っ掛けて位置決めし、後は係止爪部５４を係合孔１２ｇに押し込めば取付作業を完了でき、取付作業が容易である。また、ロック装置１０を外側部材１２の裏側から取り付けることで、取付工程で外側部材１２の表側の意匠面を傷つける可能性を低減できる。 Thus, compared with the case of fixing with screws or the like, if the hook portion 52 is hooked and positioned, and then the locking claw portion 54 is pushed into the engagement hole 12g, the mounting operation can be completed, and the mounting operation is easy. . Moreover, by attaching the locking device 10 from the back side of the outer member 12, the possibility of damaging the front-side design surface of the outer member 12 in the attaching step can be reduced.
　次に、ロータ２４、第１ロッド２６および第２ロッド２８は、予め連結された状態で、外側部材１２の裏側から取り付けられる。ロータ２４は、ロータ軸受部１２ｆに軸支され、第１ロッド２６の先端は第１支持孔部１２ｃに挿入され、第２ロッド２８の先端は第２支持孔部１２ｄに挿入される。次に、第１バネ部材３０が、ベース部材２２のバネ受け部６２に取り付けられて第１ロッド２６を付勢させ、第２バネ部材３２がバネ保持部１２ｅに取り付けられて第２ロッド２８を付勢させる。これで、ロック装置１０の取り付けが完了する。なお、第１バネ部材３０は、第１ロッド２６の取り付けより先にベース部材２２に取り付けられてよい。 Next, the rotor 24, the first rod 26, and the second rod 28 are attached from the back side of the outer member 12 in a state of being connected in advance. The rotor 24 is pivotally supported by the rotor bearing portion 12f, the tip of the first rod 26 is inserted into the first support hole 12c, and the tip of the second rod 28 is inserted into the second support hole 12d. Next, the first spring member 30 is attached to the spring receiving portion 62 of the base member 22 to urge the first rod 26, and the second spring member 32 is attached to the spring holding portion 12e to attach the second rod 28. Energize. This completes the mounting of the locking device 10. The first spring member 30 may be attached to the base member 22 before the first rod 26 is attached.
　ロック装置１０の全ての部材を外側部材１２の裏側から取り付けることができるため、取付工程において外側部材１２を裏向きに台座に載置すれば、そのままの状態でロック装置１０および開閉部材の内側部材を取り付け、開閉部材を組み立てることができ、取付作業を容易にできる。 Since all the members of the lock device 10 can be attached from the back side of the outer member 12, if the outer member 12 is placed on the pedestal in the attachment process, the lock device 10 and the inner members of the opening / closing member are left as they are. Can be assembled and the opening and closing member can be assembled, and the mounting operation can be facilitated.
　図３は、ロータ２４と第１ロッド２６と第２ロッド２８とを連結した状態の斜視図である。ロータ２４は、支持部６２、第１軸部６０ａおよび第２軸部６０ｂ（これらを区別しない場合「軸部６０」という）を有する。 FIG. 3 is a perspective view showing a state in which the rotor 24, the first rod 26, and the second rod 28 are connected. The rotor 24 includes a support portion 62, a first shaft portion 60a, and a second shaft portion 60b (referred to as “shaft portion 60” if they are not distinguished from each other).
　支持部６２は、ロータ２４の中央に形成され、図２に示すロータ軸受部１２ｆが挿入される。ロータ２４は、ロータ軸受部１２ｆに回転可能に支持される。第１軸部６０ａおよび第２軸部６０ｂは、支持部６２の回転軸に沿って柱状に立設され、支持部６２から離れて位置する。軸部６０は、先端に一対の接続部６６を有する。接続部６６は、軸部６０の円錐状の先端部から径方向外向きに張り出す。接続部６６は、成形時にロータ２４と第１ロッド２６および第２ロッド２８とを接続する。 The support portion 62 is formed at the center of the rotor 24, and the rotor bearing portion 12f shown in FIG. The rotor 24 is rotatably supported by the rotor bearing portion 12f. The first shaft portion 60 a and the second shaft portion 60 b are erected in a column shape along the rotation axis of the support portion 62 and are located away from the support portion 62. The shaft portion 60 has a pair of connection portions 66 at the tip. The connecting portion 66 projects radially outward from the conical tip portion of the shaft portion 60. The connection part 66 connects the rotor 24 to the first rod 26 and the second rod 28 during molding.
　第１ロッド２６は、基端側に第１軸孔部６８ａを有し、第２ロッド２８は、基端側に第２軸孔部６８ｂを有する。第１軸孔部６８ａおよび第２軸孔部６８ｂ（これらを区別しない場合「軸孔部６８」という）は、断面が略矩形状に形成される。図３（ａ）に示すように、軸部６０は、軸孔部６８に挿入され、軸孔部６８内で回転可能である。 The first rod 26 has a first shaft hole 68a on the base end side, and the second rod 28 has a second shaft hole 68b on the base end side. The first shaft hole portion 68a and the second shaft hole portion 68b (referred to as “shaft hole portion 68” if they are not distinguished from each other) have a substantially rectangular cross section. As shown in FIG. 3A, the shaft portion 60 is inserted into the shaft hole portion 68 and can rotate within the shaft hole portion 68.
　軸孔部６８は、ロッド２６，２８の長手方向に対向する第１壁部７０と、第１壁部７０の対向方向に直交する方向に対向する第２壁部７２と、を有する。第１壁部７０は、第２壁部７２と比べて、厚い板厚であり、剛性が高くなるように形成される。 The shaft hole portion 68 includes a first wall portion 70 facing the longitudinal direction of the rods 26 and 28 and a second wall portion 72 facing the direction orthogonal to the facing direction of the first wall portion 70. The first wall portion 70 is thicker than the second wall portion 72 and is formed to have higher rigidity.
　図４は、軸部６０および軸孔部６８の挿嵌状態について説明するための図である。図４（ａ）は第１ロッド２６の長手方向に直交する方向に沿う断面であり、図４（ｂ）は第１ロッド２６の長手方向に沿う断面である。 FIG. 4 is a view for explaining the insertion state of the shaft portion 60 and the shaft hole portion 68. FIG. 4A is a cross section along a direction orthogonal to the longitudinal direction of the first rod 26, and FIG. 4B is a cross section along the longitudinal direction of the first rod 26.
　図４（ａ）に示すように、軸部６０は、根元側に位置する小径部６５と、小径部から径方向外向きに張り出す抜け止め部６４を有する。抜け止め部６４は、軸部６０の外周面に段状に形成され、小径部６５より大径である。軸孔部６８は、第２壁部７２に段状に形成される係合部７６を有する。抜け止め部６４が係合部７６に引っ掛かって、軸部６０を軸孔部６８から抜け止めする。このように、ロータ２４とロッド２６、２８が連結された状態では、軸部６０が軸孔部６８に挿嵌された状態にあり、軸部６０および軸孔部６８の挿嵌状態では、軸部６０の軸孔部６８への挿入が完了して軸部６０の抜け止め部６４が軸孔部６８の係合部７６により抜け止めされている。 As shown in FIG. 4 (a), the shaft portion 60 has a small diameter portion 65 located on the root side and a retaining portion 64 projecting radially outward from the small diameter portion. The retaining portion 64 is formed in a step shape on the outer peripheral surface of the shaft portion 60 and has a larger diameter than the small diameter portion 65. The shaft hole portion 68 has an engaging portion 76 formed in a step shape on the second wall portion 72. The retaining portion 64 is caught by the engaging portion 76, and the shaft portion 60 is retained from the shaft hole portion 68. Thus, when the rotor 24 and the rods 26 and 28 are coupled, the shaft portion 60 is inserted into the shaft hole portion 68, and when the shaft portion 60 and the shaft hole portion 68 are inserted, the shaft portion 60 is inserted. After the insertion of the portion 60 into the shaft hole portion 68 is completed, the retaining portion 64 of the shaft portion 60 is retained by the engaging portion 76 of the shaft hole portion 68.
　図５は、ロータ２４およびロッド２６、２８の一体成形について説明するための図である。図５（ａ）はロータ２４の軸方向に見た図であり、図５（ｂ）はロッド２６、２８の長手方向に見た図である。また、図６（ａ）は、図５（ａ）に示すロータ２４および第１ロッド２６のＡ－Ａ断面図であり、図６（ｂ）は、図５（ａ）に示すロータ２４および第１ロッド２６のＢ－Ｂ断面図である。なお、図６では、第１軸部６０ａと第１軸孔部６８ａを示すが、第２軸部６０ｂと第２軸孔部６８ｂも同じ形状である。 FIG. 5 is a diagram for explaining integral molding of the rotor 24 and the rods 26 and 28. FIG. 5A is a diagram viewed in the axial direction of the rotor 24, and FIG. 5B is a diagram viewed in the longitudinal direction of the rods 26 and 28. 6A is a cross-sectional view of the rotor 24 and the first rod 26 shown in FIG. 5A taken along the line AA. FIG. 6B is a diagram showing the rotor 24 and the first rod shown in FIG. 2 is a cross-sectional view of one rod 26 taken along the line BB. FIG. 6 shows the first shaft portion 60a and the first shaft hole portion 68a, the second shaft portion 60b and the second shaft hole portion 68b have the same shape.
　図５および図６では、ロータ２４およびロッド２６、２８が、成形用の金型から取り出された際の状態であり、一体である一体成形状態を示す。ロータ２４とロッド２６、２８を一体に成形することで、製造コストを抑えることができる。 5 and 6 show a state where the rotor 24 and the rods 26 and 28 are taken out from the molding die, and show an integral molding state. Manufacturing costs can be reduced by integrally forming the rotor 24 and the rods 26 and 28.
　図５（ｂ）に示すように、第１軸部６０ａが第１ロッド２６に接続され、第２軸部６０ｂが第２ロッド２８に接続される。図６（ａ）に示すように、一対の接続部６６が、軸孔部６８の縁であり、第１壁部７０の端縁に接続している。 As shown in FIG. 5 (b), the first shaft portion 60 a is connected to the first rod 26, and the second shaft portion 60 b is connected to the second rod 28. As shown in FIG. 6A, the pair of connection portions 66 are the edges of the shaft hole portion 68 and are connected to the end edge of the first wall portion 70.
　図６（ｂ）に示すように、一体成形状態で軸部６０の先端は、軸孔部６８に入っており、接続部６６は、軸孔部６８内に位置する。 As shown in FIG. 6B, the tip end of the shaft portion 60 enters the shaft hole portion 68 in the integrally molded state, and the connection portion 66 is located in the shaft hole portion 68.
　図５（ａ）および図６（ａ）に示すように、軸部６０と軸孔部６８は一体成形状態で同じ中心軸上に位置し、同軸上に形成される。これにより、軸部６０および軸孔部６８の位置決めが不要になり、軸部６０を軸孔部６８にそのまま押すことで、回転可能な連結状態することができ、組み付け作業を容易にできる。 As shown in FIGS. 5 (a) and 6 (a), the shaft portion 60 and the shaft hole portion 68 are located on the same central axis in an integrally molded state, and are formed coaxially. Thereby, the positioning of the shaft portion 60 and the shaft hole portion 68 becomes unnecessary, and the shaft portion 60 can be pushed into the shaft hole portion 68 as it is, so that it can be connected in a rotatable state, and the assembling work can be facilitated.
　ロータ２４とロッド２６、２８との組み付け工程について説明する。ロータ２４およびロッド２６、２８は、樹脂成形により一体に成形される。次に、作業者は、軸部６０を軸孔部６８に挿入するため、軸部６０を軸孔部６８に向かって軸方向に押す。作業者の押し込みにより接続部６６が破断されて軸部６０が軸孔部６８へ進行し、抜け止め部６４が係合部７６に係合することで、軸部６０が軸孔部６８に回転可能に挿嵌される。このように、作業者は、軸部６０を軸孔部６８に押し込むだけで、ロータ２４とロッド２６、２８を容易に組み付けることができる。軸部６０を軸孔部６８に挿嵌して連結させることで、ロータ２４の回転と、第１ロッド２６および第２ロッド２８の進退との連動性を向上できる。 The assembly process of the rotor 24 and the rods 26 and 28 will be described. The rotor 24 and the rods 26 and 28 are integrally formed by resin molding. Next, the operator pushes the shaft portion 60 in the axial direction toward the shaft hole portion 68 in order to insert the shaft portion 60 into the shaft hole portion 68. When the operator pushes in, the connecting portion 66 is broken, the shaft portion 60 advances to the shaft hole portion 68, and the retaining portion 64 engages with the engaging portion 76, whereby the shaft portion 60 rotates into the shaft hole portion 68. Inserted as possible. As described above, the operator can easily assemble the rotor 24 and the rods 26 and 28 simply by pushing the shaft portion 60 into the shaft hole portion 68. By inserting and connecting the shaft portion 60 to the shaft hole portion 68, the linkage between the rotation of the rotor 24 and the advance and retreat of the first rod 26 and the second rod 28 can be improved.
　変形例では、軸部６０が軸孔部６８に挿嵌される工程は、ロータ２４およびロッド２６、２８を金型から取り出す際に実行されてよい。たとえば、金型から一体成形されたロータ２４およびロッド２６、２８を取り出す際に、押し出しピンでロータ２４のみを押して接続部６６を破断させ、軸部６０が軸孔部６８に挿嵌されると、金型からロータ２４およびロッド２６、２８が取り出せるように構成されてよい。また、金型から一体成形されたロータ２４およびロッド２６、２８を取り出す際に、押し出しピンでロッド２６、２８のみを押して接続部６６を破断させ、軸部６０が軸孔部６８に挿嵌されると、金型からロータ２４およびロッド２６、２８が取り出せるように構成されてよい。 In a modification, the step of inserting the shaft portion 60 into the shaft hole portion 68 may be performed when the rotor 24 and the rods 26 and 28 are taken out from the mold. For example, when the rotor 24 and the rods 26, 28 integrally formed from the mold are taken out, only the rotor 24 is pushed with the push pin to break the connection portion 66, and the shaft portion 60 is inserted into the shaft hole portion 68. The rotor 24 and the rods 26 and 28 may be removed from the mold. Further, when the rotor 24 and the rods 26, 28 integrally formed from the mold are taken out, only the rods 26, 28 are pushed by the push pins to break the connection portion 66, and the shaft portion 60 is inserted into the shaft hole portion 68. Then, the rotor 24 and the rods 26 and 28 may be configured to be taken out from the mold.
　図４（ｂ）に示すように、一対の第１壁部７０は、軸孔部６８の縁を凹むように形成させる凹部７４を有する。凹部７４は、軸部６０の挿入方向の奥側に位置する。連結状態において、軸部６０の先端部は、軸孔部６８の内面と干渉しないように位置する。つまり、軸部６０の先端側の接続部６６は、軸孔部６８の内面と離間した状態にある。凹部７４により、接続部６６に残ったバリが軸孔部６８に干渉せず、軸部６０を軸孔部６８内でスムーズに回転させることができる。 As shown in FIG. 4B, the pair of first wall portions 70 have recesses 74 that are formed so as to recess the edges of the shaft hole portion 68. The concave portion 74 is located on the far side in the insertion direction of the shaft portion 60. In the connected state, the tip portion of the shaft portion 60 is positioned so as not to interfere with the inner surface of the shaft hole portion 68. That is, the connecting portion 66 on the distal end side of the shaft portion 60 is in a state of being separated from the inner surface of the shaft hole portion 68. Due to the recess 74, the burr remaining in the connection portion 66 does not interfere with the shaft hole portion 68, and the shaft portion 60 can be smoothly rotated in the shaft hole portion 68.
　また、図４（ｂ）に示すように、軸部６０の根元側に小径部６５を形成することで、第１壁部７０における接続部６６との破断部分７５が軸部６０に干渉しないように構成でき、軸部６０を軸孔部６８内でスムーズに回転させることができる。第１壁部７０の破断部分７５は、軸部６０の挿入方向の手前側で、軸孔部６８の縁に位置する。 Further, as shown in FIG. 4B, by forming the small diameter portion 65 on the base side of the shaft portion 60, the fracture portion 75 of the first wall portion 70 with the connection portion 66 does not interfere with the shaft portion 60. The shaft portion 60 can be smoothly rotated in the shaft hole portion 68. The fracture portion 75 of the first wall portion 70 is positioned at the edge of the shaft hole portion 68 on the near side in the insertion direction of the shaft portion 60.
　図６（ａ）に示すように、第１壁部７０は、一体成形状態で、接続部６６に接続する。第１壁部７０が第２壁部７２より撓みにくいため、接続部６６を破断させやすくできる。接続部６６は、連結状態で第１壁部７０に当接または近接し、軸部６０のガタつきを抑える。なお、接続部６６を破断させやすくするため、接続部６６に切り込みを形成してもよい。 As shown in FIG. 6A, the first wall portion 70 is connected to the connection portion 66 in an integrally molded state. Since the first wall portion 70 is more difficult to bend than the second wall portion 72, the connection portion 66 can be easily broken. The connecting portion 66 is in contact with or close to the first wall portion 70 in a connected state, and suppresses rattling of the shaft portion 60. In addition, in order to make the connection part 66 easy to fracture | rupture, you may form a notch in the connection part 66. FIG.
　図４（ａ）に示すように、第２壁部７２に係合部７６を形成することで、軸部６０を軸孔部６８に押し込む際に、抜け止め部６４が第２壁部７２を撓ませて係合部７６に係合する。第２壁部７２が第１壁部７０より撓みやすいため、軸部６０を軸孔部６８に挿入しやすくできる。 As shown in FIG. 4A, by forming the engaging portion 76 in the second wall portion 72, when the shaft portion 60 is pushed into the shaft hole portion 68, the retaining portion 64 pushes the second wall portion 72. It bends and engages with the engaging portion 76. Since the second wall portion 72 is more easily bent than the first wall portion 70, the shaft portion 60 can be easily inserted into the shaft hole portion 68.
　図７は、変形例の一体成形状態のロータ２４、第１ロッド２６および第２ロッド２８について説明するための図である。変形例のロータ２４、第１ロッド２６および第２ロッド２８は、図５（ａ）に示すロータ２４、第１ロッド２６および第２ロッド２８に比べて、第１ロッド２６および第２ロッド２８の配置が異なる。 FIG. 7 is a view for explaining the rotor 24, the first rod 26, and the second rod 28 in the integrally formed state of a modified example. The rotor 24, the first rod 26, and the second rod 28 of the modified example are different from the rotor 24, the first rod 26, and the second rod 28 shown in FIG. The arrangement is different.
　変形例では、第１ロッド２６および第２ロッド２８は、一体成形状態で並列に配置される。つまり、第１ロッド２６および第２ロッド２８は、軸孔部６８が形成される基端側から先端側に延びる方向が同じで、平行に配置される。これにより、一体成形状態の第１ロッド２６および第２ロッド２８の長手方向の長さを短くして、金型を小さくし、一体成形状態での搬送を容易にできる。 In the modification, the first rod 26 and the second rod 28 are arranged in parallel in an integrally molded state. That is, the first rod 26 and the second rod 28 have the same direction extending from the proximal end side where the shaft hole portion 68 is formed to the distal end side, and are arranged in parallel. Thereby, the length of the longitudinal direction of the 1st rod 26 and the 2nd rod 28 of an integrally molded state can be shortened, a metal mold | die can be made small, and the conveyance in an integrally molded state can be made easy.
　図８は、第２実施例のロータ１２４、第１ロッド１２６および第１ロッド１２６について説明するための図である。図８（ａ）はロータ１２４の軸方向に見た図であり、図８（ｂ）はロッド１２６、１２８の長手方向に見た図である。また、図９（ａ）は、図８（ａ）に示すロータ１２４および第１ロッド１２６のＣ－Ｃ断面図であり、図９（ｂ）は、図８（ａ）に示すロータ１２４および第１ロッド１２６のＤ－Ｄ断面図である。 FIG. 8 is a diagram for explaining the rotor 124, the first rod 126, and the first rod 126 of the second embodiment. 8A is a view as seen in the axial direction of the rotor 124, and FIG. 8B is a view as seen in the longitudinal direction of the rods 126 and 128. 9A is a cross-sectional view of the rotor 124 and the first rod 126 shown in FIG. 8A taken along the line CC, and FIG. 9B is a diagram showing the rotor 124 and the first rod 126 shown in FIG. 2 is a DD cross-sectional view of one rod 126. FIG.
　第２実施例のロータ１２４およびロッド１２６、１２８は、図５（ｂ）に示す第１実施例のロータ２４およびロッド２６、２８と比べて、軸部１６０と軸孔部１６８が形成される部材が逆である。つまり、ロータ１２４に軸孔部１６８が形成され、ロッド１２６、１２８に軸部１６０が形成される。 The rotor 124 and the rods 126 and 128 of the second embodiment are members in which the shaft portion 160 and the shaft hole portion 168 are formed as compared with the rotor 24 and the rods 26 and 28 of the first embodiment shown in FIG. Is the opposite. That is, the shaft hole portion 168 is formed in the rotor 124, and the shaft portion 160 is formed in the rods 126 and 128.
　図８（ｂ）に示すように、第１ロッド１２６および第２ロッド１２８に、柱状の軸部１６０がそれぞれ形成される。図９（ｂ）に示すように、軸部１６０は、軸部１６０の先端部に形成される接続部１６６により、軸孔部１６８の縁に接続される。 As shown in FIG. 8B, columnar shaft portions 160 are formed on the first rod 126 and the second rod 128, respectively. As shown in FIG. 9B, the shaft portion 160 is connected to the edge of the shaft hole portion 168 by a connection portion 166 formed at the distal end portion of the shaft portion 160.
　図９（ａ）および図９（ｂ）に示すように、軸部１６０と軸孔部１６８は一体成形状態で同じ中心軸上、すなわち同軸上に形成される。これにより、軸部１６０を軸孔部１６８にそのまま押せば挿嵌できる。 9A and 9B, the shaft portion 160 and the shaft hole portion 168 are formed on the same central axis, that is, coaxially, in an integrally molded state. Accordingly, the shaft portion 160 can be inserted by being pushed into the shaft hole portion 168 as it is.
　図１０は、第２実施例のロータ１２４、第１ロッド１２６および第２ロッド１２８の連結状態の斜視図である。連結状態では、軸部１６０が軸孔部１６８に挿通されている。軸孔部１６８の周りにスリット１６９が形成されており、軸孔部１６８が拡開するように撓み可能に形成される。スリット１６９により、軸部１６０の押し込みを容易にできる。 FIG. 10 is a perspective view of the coupled state of the rotor 124, the first rod 126 and the second rod 128 of the second embodiment. In the connected state, the shaft portion 160 is inserted through the shaft hole portion 168. A slit 169 is formed around the shaft hole portion 168, and the shaft hole portion 168 is formed to be able to bend so as to expand. The slit 169 can easily push the shaft portion 160.
　ロータ１２４とロッド１２６、１２８との組み付け工程について説明する。第２実施例でも、ロータ１２４およびロッド１２６、１２８は、樹脂成形により一体に成形される。作業者は、軸部１６０を軸孔部１６８に挿入するため、軸部１６０を軸孔部１６８に向かって軸方向に押す。作業者の押し込みにより接続部１６６が破断されて軸部１６０が軸孔部１６８へ進行し、抜け止め部１６４が軸孔部１６８の縁に係合することで、軸部１６０が軸孔部１６８に回転可能に挿嵌される。 The assembly process of the rotor 124 and the rods 126 and 128 will be described. Also in the second embodiment, the rotor 124 and the rods 126 and 128 are integrally formed by resin molding. The operator pushes the shaft portion 160 in the axial direction toward the shaft hole portion 168 in order to insert the shaft portion 160 into the shaft hole portion 168. The connection portion 166 is broken by the operator's pressing, the shaft portion 160 advances to the shaft hole portion 168, and the retaining portion 164 engages with the edge of the shaft hole portion 168, so that the shaft portion 160 becomes the shaft hole portion 168. It is inserted in a rotatable manner.
