（参考例）
本例は、図８、図９に示すごとく、被取付部材３が環状に形成されているステータコア１の例である。
被取付部材３は、ヨーク部２１に係合する係合爪部３３を複数有する。係合爪部３３によって被取付部材３が磁気回路部材２に固定されている。 ( Reference example )
This example is an example of the stator core 1 in which the attached member 3 is formed in an annular shape as shown in FIGS.
The mounted member 3 has a plurality of engaging claw portions 33 that engage with the yoke portion 21. The attached member 3 is fixed to the magnetic circuit member 2 by the engaging claw 33.

（実施例２）
本例は、図１０〜図１２に示すごとく、磁気回路部材２と被取付部材３とが金属製の連結部材６によって互いに連結固定されているステータコア１の例である。
連結部材６は、図１０、図１１に示すごとく、磁気回路部材２と被取付部材３との間に介設される筒状体６１と、筒状体６１からそれぞれ複数突出した第１係合爪部６３１及び第２係合爪部６３２とを有する。複数の第１係合爪部６３１が被取付部材３に係合され、複数の第２係合爪部６３２が磁気回路部材２に係合されることにより、被取付部材３と磁気回路部材２とが互いに固定されている。 (Example 2 )
This example is an example of the stator core 1 in which the magnetic circuit member 2 and the mounted member 3 are connected and fixed to each other by a metal connecting member 6 as shown in FIGS.
As shown in FIGS. 10 and 11, the connecting member 6 includes a cylindrical body 61 interposed between the magnetic circuit member 2 and the attached member 3, and a plurality of first engagements each protruding from the cylindrical body 61. It has a claw part 631 and a second engagement claw part 632. The plurality of first engaging claws 631 are engaged with the attached member 3, and the plurality of second engaging claws 632 are engaged with the magnetic circuit member 2, whereby the attached member 3 and the magnetic circuit member 2 are engaged. And are fixed to each other.

図１０、図１１に示すごとく、各被取付部材３は、一対の鍔部３２が第１係合爪部６３１によって係合され、かしめられることにより、連結部材６に固定される。各鍔部３２には、軸方向に対向する一対の第１係合爪部６３１が係合している。また、第２係合爪部６３２は、磁気回路部材２のヨーク部２１に係合し、かしめられている。第２係合爪部６３２の磁気回路部材２への係合の状態は、参考例（図８、図９）における係合爪部３３による磁気回路部材２への係合の状態と略同様である。 As shown in FIGS. 10 and 11, each mounted member 3 is fixed to the connecting member 6 by the pair of flange portions 32 being engaged and caulked by the first engaging claw portions 631.
