Later, the endless groove 27 on the composition surface of receiving portion 22 is set to is embedded in the 1st seal member 30.
Solenoid part 1 and the assembling in ozzle portion 2 carry out as follows.
(1) flex portion 10c is in the outside that the housing 10 of extended configuration covers on from axial one end solenoid part 1, led to
It crosses the edge of the periphery of metallic plate 19 and to abut to carry out axial positioning with stage portion 10b.
(2) in cover lower housing 10, by being inserted into the protrusion 13a of iron core 13 in the hole portion 10a of housing 10, so as to carry out
The circumferential positioning of housing 10.
(3) from axial another side insertion ozzle portion 2 in the opening portion of housing 10.At this point, it is inserted into receiving portion 22
The guide member 14 and plunger pin 15, the axial other end of plunger pin 15 protruded from metallic plate 19 is contacted with spool 25.
(4) simultaneously, metal parts 26 is be overlapped with metallic plate 19, and the edge of the periphery of the two is configured in the step of housing 10
The part of portion 10b, the axial other end of the flex portion 10c of extended configuration are dashed forward than the axial another side surface of metal parts 26
Go out.
(5) by by flex portion 10c to central shaft side calking, so as to clamp gold between stage portion 10b and flex portion 10c
Belong to component 26 and metallic plate 19, solenoid part 1 and ozzle portion 2 are fixed together.
(6) by the calking of flex portion 10c, flange part 11b, metallic plate 19 and the metal parts 26 of bobbin winder bracket 11 are in axis
Strongly pressed upwards, the 1st seal member 30 and the 2nd seal member 31 deform, between flange part 11b and metallic plate 19 between
Gap between gap and metallic plate 19 and ozzle portion 2 is sealed.
The electromagnetic valve device manufactured in the above described manner is by being partially submerged into resin pipe mouth 20 to being set to speed changer
It is mounted on control valve in the mounting hole of the solenoid valve of control valve.In this case, it is set to the peripheral surface of ozzle 20
Seal member 20a can block the gap between the inner peripheral surface of mounting hole and the peripheral surface of ozzle 20, prevent the leakage of oil.
More than, according to illustrative implementation structure, it can be anticipated that following effect.
(1) it is separate structure to make solenoid part 1 and ozzle portion 2, by the two by calking processing come be fixed together so as to
Electromagnetic valve device is formed, therefore, it is possible to by the solenoid part 1 to different size and ozzle portion 2 suitably select and combine,
So as to simply manufacture various electromagnetic valve devices.
(2) metallic plate is clamped by the flex portion 10c and stage portion 10b of the opening portion for being set to metal housing 10
19 and metal parts 26 this two panels, firmly fix solenoid part 1 and ozzle portion 2 so as to the high metal of use intensity.
(3) it is configured in endless groove 27 due to having, the be sealed to the axial one end in ozzle portion 2 and metallic plate 19
1 seal member 30, therefore, solenoid part 1 and ozzle portion 2 by the calking of housing 10 and by it is fixed when, the linking part of the two
The gap divided is sealed by the 1st seal member 30.
As a result, even if due to the hydraulic pressure from the 1st port 23 and 24 part of the 2nd port, oil is along plunger pin 15, column
Plunger member 15a or guide member 14 reach the linking portion of the two, the 1st seal member can also be utilized to prevent the oil from escaping to outer
Portion.
(4) surface that the axial one end by the axial other end of bobbin winder bracket 11 and metallic plate is configured to due to having is close
The 2nd seal member 31 contiguously clamped, therefore, it is possible to the oil that prevents from leaking out from port section along plunger part 15a and
Guide member 14 and escape to outside from the gap between the flange part 11b of bobbin winder bracket 11 and metallic plate 19.
(5) there is slot 13c and the 3rd seal member 32, the slot 13c is hollowly circumferentially arranged in axial the one of iron core 13
The circumferential surface of end side, the 3rd seal member 32 are configured in slot 13c, and iron core 13 and bobbin winder bracket are clamped in compressive state
Between 11, therefore, it is possible to the oil that prevents from leaking out from port section along plunger part 15a and guide member 14, even line
Circle 13, the gap between the inner peripheral surface of the cylindrical portion 11a of bobbin winder bracket 11 and the peripheral surface of coil 13 escape to outside.
(6) due to being provided with the 4th seal member 33 between the flange part 11c of bobbin winder bracket 11 and the inner surface of housing 10,
Therefore, it is possible to prevent external moisture from passing through the inner surface of housing 10 and resin component 17 from the edge of the opening portion of housing 10
Gap between peripheral surface enters inside device.
(7) metal parts 26 is the cricoid component for having opening portion in center, and peripheral part has to be stretched to radial outside
The flange part 26a gone out, inner peripheral portion have the embedded division 26b for the inside for being embedded in the resin for forming ozzle 20, therefore, it is possible to only logical
Cross 10 independent fixed metal plate 19 of housing and metal parts 26 it is entire around, can be by simple inner surface structure by spiral shell
Spool portion 1 and ozzle portion 2 are fixed together.Especially since the embedded division 26b of metal parts 26 is embedded in the tree in ozzle portion 2
In fat, therefore, in ozzle portion 2 when being molded, can metal portion be simply fixed with high intensity by insert-molding
Part 26.
(8) due to being provided with the circular protrusion 11d protruded towards metallic plate 19 in the axial other end of bobbin winder bracket 11, at this
The radial outside of circular protrusion 11d is configured with the 2nd seal member 31, therefore, it is possible to using circular protrusion 11d come accurately to
2 seal members 31 are positioned.
(9) spring 16 and plunger part 15a are provided between iron core 13 and plunger pin 15, therefore, from closing housing
The component that the centrally disposed opening portion of the metallic plate 19 of 10 opening portion is exposed is more.Therefore, by from solenoid part 1 and ozzle
The water of gap intrusion between portion 2 and the component of oil pollution damage are more, the reason of easily becoming failure, and in the present embodiment,
Since the gap between solenoid part 1 and ozzle portion 2 is sealed by the 3rd seal member 32, the dirt of these components will not be generated
Damage, the reliability of device are improved.
(10) since the axial one end in iron core 13 is provided with protrusion 13a, the upper axial end of housing 10 is provided with confession

(3) due to using between the inner surface of the 5th seal member 34 closing housing 10 and the peripheral surface of resin component 17
Gap, therefore can prevent gap of the oil between plunger pin 15 and iron core 13 from passing through the inner peripheral surface of bobbin winder bracket 11 and iron core 13
Gap between peripheral surface escapes to outside.
(4) since the 6th seal member 35 to be configured to circumferential surface complete cycle and ozzle in the one end of iron core 13 in intimate contact
Between the inner surface of 20 hollow portion 21, by clearance seal between the two, between preventing oil from passing through between the two
Gap escapes to outside.
(5) since the 7th seal member 36 to be configured to the flange part 13d on the surface of the one end of bobbin winder bracket 11 and iron core 13
Between, therefore, it is possible to prevent the oil of the axial one end from iron core 13 pass through bobbin winder bracket 11 inner peripheral surface and iron core 13 it is outer
Gap between circumferential surface and escape to outside.Also, due to clamping the 7th seal member by flange part 13d and bobbin winder bracket 11
36, therefore, it is possible to easily carry out the positioning of the 7th seal member 36.
The utility model be not limited to more than illustrative implementation structure.Above illustrative implementation structure is conduct
