PROBLEM TO BE SOLVED: To exhaust air to an outside at the time of resin injection and to suppress formation of voids.SOLUTION: A through-hole 32 passing through a stator core 30 in an axial direction is formed. A groove 45 causing two grooves 44a and 44b and the through-hole 32 to communicate with one another is formed while the two grooves 44a and 44b causing an outer peripheral side and an inner peripheral side of the stator core 30 to communicate with each other are being formed on a contact surface 42 of a three-phase terminal fixing member 40. On this account, air between the stator core 30 and a stationary mold 12 can be exhausted to outside the outer peripheral side of the stator core 30 via the through-hole 32, the grooves 45 and the grooves 44a and 44b, air between the stator core 30 and a movable mold 14 can be exhausted to outside the outer peripheral side of the stator core 30 via the grooves 44a and 44b at the time of resin injection, and formation of voids generated by the air remaining between the stator core 30 and the stationary mold 12 or the stationary mold 14 can be suppressed.SELECTED DRAWING: Figure 1 |
