And through between two faces of packing ring 47.Slit 547b has the shape of closing, and the shape of this closing is that do not having lead 45
And when packing ring 47 is installed on recess 52c sealing resin 56 will not spill close-shaped.Slit 547b is from container 52 opening
Edge 52b along container 52 depth direction extend.Slit 547b provides the maintaining part keeping lead 45 in sealed states.Narrow
Seam 547b can be formed by the cutting action of packing ring 47 or forming process.
Packing ring 47 has multiple slit 547b.Multiple slit 547b are parallel to each other.Packing ring 47 has along edge 52b on a large scale
Extension and 3 slit 547b being distributed.One slit 547b has the size that can receive many leads 45.Illustrate shows
In example, in a slit 547b, it is configured with 2 leads 45.
In the manufacture method of electric rotating machine 10, lead 45 is radially pressed in slit 547b.Packing ring 47 is with from drawing
The radial outside of line 45 is installed on lead 45 into slit 547b in the way of encasing lead 45.The bullet by itself for the packing ring 47
Property, or natural resiliency and the pushing force producing because being incorporated in recess 52c, make inner surface and lead 45 phase of slit 547b
Contact.Reliably carry out the closely sealed of packing ring 47 and lead 45 by setting the magnitude of interference that compressed in recess 52c of packing ring 47.
At least after packing ring 47 is installed on recess 52c, packing ring 47 is made in slit 547b in the way of stoping sealing resin 56 from spilling
Surface is closely sealed with lead 45.
Slit 547b can be in the optional position of lead 45, and lead 45 is combined by the radial direction along lead 45 with packing ring 47.Cause

It is arranged with 3 leads 45.According to this embodiment, many leads 45 being capable of centralized configuration.
(the 7th embodiment)
Present embodiment is by the variation of embodiment based on formerly embodiment.In the above-described embodiment,
Lead 45 configures in through hole 47a or slit 547b.Instead, in the present embodiment, lead 45 configures in groove
In 747c.
As shown in figure 9, packing ring 47 has the groove 747c being properly termed as U-shaped or V-shaped.Groove 747c is from the edge of packing ring 47
Portion extends towards in packing ring 47, and through between two faces of packing ring 47.Groove 747c has, even if not having lead 45 and padding
Circle 47 also still can connect the size in two faces of packing ring 47 in the case of being arranged on recess 52c.Groove 747c, by lead
45 are radially pushed in groove 747c and for lead 45 to be maintained at sealing state.In the manufacture method of electric rotating machine 10, draw
Line 45 radially enters in groove 747c.
Groove 747c has the size that can receive many leads 45.In order to fill between the inner surface of groove 747c and lead 45
Gap and lead 45 and lead 45 between gap, bonding agent or gap filler can be applied.
According to this embodiment, on packing ring 47, many leads 45 can be become a branch of state.As a result, many
Lead 45 can be configured to extend from packing ring 47 with wire harness state.Further, it is possible to make the width of packing ring 47 diminish.Thus, draw
Line 45 will not be configured by the outer surface along housing 51.Therefore, on minimizing housing 51 outer surface, exposing of lead 45 is reduced.
