  Thereafter, synthetic resin is injected into the cavity from an injection hole (not shown), and the first peripheral wall portion 1, the connector connecting portion 2, the second peripheral wall portion 3, the partition portion 4, the terminal concentrating portion 5 and the like shown in FIG. When integrally molded in one step, a housing 400 in which the coil conductor member 6, the sensor conductor member 7, the motor conductor member 8, the terminal unit 44, and the tubular member 45 are insert-molded is obtained. When the housing 400 is taken out from the lower mold 10 or the like, the connecting portions 41a, 41b, 42a, 42b, and 43a (see FIG. 4) of the conductor units 41, 42, and 43 exposed from the opening 4e (see FIG. 4) of the partition portion 4 and the like. 10) and the like.

  According to the housing 400 described above and the manufacturing method thereof, the conductor units 41, 42, 43 are positioned by the lower mold 10 used when injection-molding the housing 400, and then the lower mold 10 and the upper mold 20 are used to form the conductor members. Since the first terminals 6a, 7a, 8a of 6, 7, and 8 can be firmly held, the partition portion 4 in which the conductor members 6, 7, and 8 are embedded is designated as the first peripheral wall portion 1 and the first peripheral portion. Even if the molding is performed together with the two-wall portion 3 or the like, the positions of the conductor members 6, 7, and 8 are not shifted by the pressure at the time of injection molding. That is, according to the housing 400, since it is not necessary to make the partition part 4 as a separate part, it is possible to reduce the number of injection moldings and, in turn, it is possible to reduce the manufacturing cost of the housing 400.

  Further, according to the housing 400, the first terminals 6a, 7a, 8a are provided with the support portion 5a that supports the first terminals 6a, 7a, 8a from the back side (the first storage chamber K1 side), so the first terminals 6a, 7a, 8a are electronically controlled. It is possible to suppress the bending that occurs in the first terminals 6a, 7a, and 8a when performing an operation (for example, wire bonding or the like) for connecting the lead wires leading to the unit 300, and thus the work for connecting the lead wires is efficient. It becomes possible to perform well and stably.
