Fig. 3 to Fig. 5 is the initial stage of the attended operation for the inserted sleeve for representing present embodiment, interstage respectively
And complete the sectional view of each state in stage.In addition, (a) and (b) in Fig. 6 to Fig. 8 was represented in above-mentioned each stage respectively
The enlarged drawing of relation between the front end of the engagement pawl and insert port 10a of existing structure and present embodiment.
First, the initial stage of attended operation is illustrated with reference to Fig. 3 and Fig. 6.As shown in figure 3, by insert 10
In the receiving port of insert port insertion receiver member 20 '.At this time, the corner 11p of the outer circumferential side of the leading edge portion 11 of insert 10 with
The above-mentioned inclination face 24a1 ' abuttings of engagement pawl 24 ', make engagement pawl 24 ' towards the direction in the opening 26a for entering pawl seat 26
(outer circumferential side) is mobile.It should be noted that what the corner 11p for the outer circumferential side that above-mentioned zone includes leading edge portion 11 was contacted at first
Tilt the part of face 24a1 '.In addition, above-mentioned zone at least has the scope between outer boundaries o ' and inboard boundary i ', its
In, outer boundaries o ' is located to compare to incline with the radial direction position correspondence of the corner 11p of the outer circumferential side of leading edge portion 11
The surface portion of inclined plane part 24a1 ' is closer at the position of above-mentioned outer rim o sides, and inboard boundary i ' is positioned at comparing above-mentioned surface portion
Closer at the position of above-mentioned inner edge i sides.
At this time, in existing structure, as shown in (a) in Fig. 6, the above-mentioned zone for tilting face 24a1 of inner peripheral surface 24a
Curvature on the virtual plane vertical with the axis of receiving port 20a, more than the curvature of the outer circumferential surface of leading edge portion 11.Cause
This, tilt face 24a1 above-mentioned virtual plane on surface location s and leading edge portion 11 outer circumferential side corner 11p it
Between circumferencial direction central portion office produce gap g.Therefore, the corner 11p of the outer circumferential side of leading edge portion 11 only with inclined plane
The left and right crestal line portion contact of portion 24a1, so as to produce the contact site te of point-like.But, it is illustrated that situation represent be insert port
The center of 10a insertion receiving ports 20a, and the state that insert port 10a is consistent with the axis of receiving port 20a.But actual feelings
Under condition, insert port 10 is inserted into sometimes relative to receiving port 20a eccentric positions or opposite with the axis of insert port 10a
In the posture insertion that the axis of receiving port 20a is slightly tilted.Therefore, the corner 11p of the outer circumferential side of leading edge portion 11 is only with one
A crestal line portion in the left and right crestal line portion of a engagement pawl 24 abuts and produces contact site te, thus causes engagement pawl 24 in circumference
Stress on direction, so as to cause engagement pawl 24 not smooth enough relative to the disengaging action of the opening 26a of pawl seat 26.
For example, in the case where example as shown is configured with three engagement pawls 24 in a circumferential direction like that, in existing knot
In structure, the corner 11p of leading edge portion 11 is limited by six contact points on circumferencial direction.But if insert port 10a phases
For the axis of receiving port 20a it is slightly off or tilt, then can produce engagement pawl 24 and be subject to huge power at some contact point,
And situation about not stressing at other contact points.The position for being additionally, since the contact point of stress is located at the circumference of each engagement pawl 24
In the crestal line portion (contact site te) of direction end, thus compared to the component of radial direction it is easier to produce in engagement pawl 24
The component of raw circumferencial direction.Thus, it is difficult to swimmingly carry out extruding engagement pawl 24 using corner 11p and making it into pawl seat 26
The action being open in 26a, therefore, in the initial stage of attended operation, insert port 10a is difficult to be inserted into receiving port 20a, easily produces
The situation collided or blocked.
On the other hand, in the present embodiment, as shown in (b) in Fig. 6, inner peripheral surface 24a's ' tilts face 24a1's '
Curvature on the above-mentioned virtual plane of above-mentioned zone is consistent with the curvature of the outer circumferential surface of leading edge portion 11.Therefore, face is tilted
Between the corner 11p of the outer circumferential side of surface location s ' and leading edge portion 11 on the above-mentioned virtual plane of 24a1 ', entirely justifying
It is difficult to produce above-mentioned gap g in circumferential direction.Therefore, in the above-mentioned zone for tilting face 24a1 ', outside leading edge portion 11
States or close state of the corner 11p of side in the gamut ta on above-mentioned virtual plane in line contact.
Thus, the initial stage even if described above in attended operation is inserted into eccentric position or is inserted into inclination attitude, due to inclined plane
The curvature of portion 24a1 ' is larger, so that also the other positions easily outside the end of circumferencial direction also equably produce insert port
The contact position of the corner 11p of 10a.Therefore, the suffered power of engagement pawl 24 ' is not easy to be inclined to circumferencial direction, and easily towards half
On the outside of the direction of footpath, therefore, the smooth degree for easily maintaining engagement pawl 24 ' to be acted relative to the disengaging of the opening 26a of pawl seat 26.
In general, the inclination face 24a1 ' of initial stage and the corner 11p engagement pawls 24 ' contacted at first in attended operation
Above-mentioned zone in, curvature on the virtual plane vertical with axis is less than the curvature of path side part 12a, and compares path side
Curvature of the part 12a closer to major diameter side part 11a.Alternatively, in above-mentioned zone, on the virtual plane vertical with axis
Curvature is less than the curvature of at least main part 24a2 ' of inner peripheral edge portion.Therefore, the corner 11p of leading edge portion 11 is with engaging
The contact condition of pawl 24 ' is closer to line contact condition rather than point contact state, the circle that engagement pawl 24 ' is subject to from corner 11p
Component in circumferential direction is less than existing structure, correspondingly, the component increase of radial direction.Therefore, engagement pawl 24 ' is than existing
Structure is easier into the opening 26a of pawl seat 26, therefore, can be swimmingly by insert port in the initial stage of attended operation
In 10a insertion receiving ports 20a.
In addition, with the inside that insert port 10a is gradually inserted to receiving port 20a as described above, the inclined plane of engagement pawl 24 '
Portion 24a1 ' is guided for the corner 11p of the outer circumferential side of the leading edge portion 11 of insert port 10a, so that insert port 10a
Eccentric position or inclination attitude are corrected.At this time, in existing structure, as described above only in the circumferencial direction of each engagement pawl 24
On left and right crestal line portion at contacted with the contact site te of point-like, thus guiding function is restricted.In contrast, in this embodiment party
In formula, since the curvature for tilting face 24a1 ' of engagement pawl 24 ' is big, it is thus possible to which diagonal section p is played on whole circumference direction
Guiding function.Therefore, in the initial stage of attended operation, successfully can be modified to insert port 10a can be with receiving port
The position of 20a connections and angle.Therefore, it can not only prevent the state that can not be inserted into is produced because of collision or can not be pulled and pushed
State, additionally it is possible to obtain from initial stage during attended operation to smoothly installing sense during interstage transition.
Here, in the case that the curvature on the above-mentioned virtual plane of above-mentioned zone is more than the curvature of major diameter side part 11a,
It is preferred that increase the radius of rounded shapes or the width of chamfer shape of above-mentioned crestal line portion J1 in the same manner as aftermentioned crestal line portion J2.By
This, can somewhat reduce radial direction height of the engagement pawl 24 ' at the corner 11p of the outer circumferential side of leading edge portion 11, so that
Gap g can be reduced.Therefore, it is possible to somewhat increase the radial direction stroke surplus of the engagement pawl 24 ' in initial stage, therefore,
Also can suppress because eccentric position or inclination attitude and there is a situation where the connection of occlusion etc. is bad.In addition, it can also mitigate
The Cat-in resisting force during attended operation of initial stage.
In addition, the present invention is not limited in present embodiment, as long as the curvature on the above-mentioned virtual plane of above-mentioned zone exists
Curvature compared to above-mentioned path side part 12a is closer to below the curvature of the curvature of major diameter side part 11a, in addition, only
Will curvature of the curvature less than at least main part 24a2 ' of inner peripheral edge portion.At this time, above-mentioned zone is above-mentioned virtual flat
Curvature on face can also be that the curvature of the curvature smaller than above-mentioned major diameter side part 11a (has the radius of curvature R b of bigger
Curvature).In this case, as shown in the double dot dash line in (b) of Fig. 6, the surface on the above-mentioned virtual plane of face 24a1 ' is tilted
The curvature of position s " is less than the curvature of the corner 11p of the outer circumferential side of leading edge portion 11.Therefore, corner 11p is not easy and engagement pawl
The left and right end edge portion tap of the 24 ' above-mentioned zone for tilting face 24a1 ' is touched, and easily the central portion with above-mentioned zone taps
Touch.Therefore, the component for the circumferencial direction that engagement pawl 24 ' is subject to becomes smaller, and the component of radial direction becomes much larger, thus energy
Enough disengaging actions further suppressed to engagement pawl 24 ' cause obstacle.
Insert port 10a obtains certain relative to the eccentric position or inclination attitude of receiving port 20a in above-mentioned initial stage
In the state of degree is corrected, further by insert port 10a insertion receiving ports 20a.Then, as shown in figure 4, being changed into engagement pawl
The main part 24a2 ' and left and right end edge portion 24a3 ' of 24 ' inner peripheral edge portion are moved to the outer circumferential surface of leading edge portion 11
State (interstage) on (i.e. major diameter side part 11a).In this condition, as shown in fig. 7, in existing structure and this embodiment party
It is that the big inner peripheral edge portion of curvature (at least main part 24a2,24a2 ') is configured in the small leading edge portion of curvature in formula
On 11 outer circumferential surface.Thus, the crestal line portion J2 and the outer circumferential surface of leading edge portion 11 for being changed into only left and right in inner peripheral edge portion are connecing
The state contacted at contact portion tf, tg.
At this time, in the present embodiment, left and right crestal line can also be increased as the main part 24a2 ' of inner peripheral edge portion
The radius of the rounded shapes of portion J2 or the width of chamfer shape (with reference to Fig. 7 and Fig. 8).Thus, by varying crestal line portion J2 with before
Contact site tg between the outer circumferential surface of end edge edge 11, can somewhat reduce engagement pawl 24 ', leading edge portion 11 outer circumferential surface
On radial direction height, so as to reduce gap g '.Therefore, it is possible to somewhat increase the interstage engagement pawl 24 ' half
The stroke surplus in footpath direction, thus can also suppress because inclination attitude and there is a situation where occlusion etc. connection it is bad.In addition,
Also the Cat-in resisting force during attended operation in interstage can be reduced.And then as shown in Figure 1, can also partly it reduce above-mentioned
The curvature of the left and right end edge portion 24a3 ' of the inner side of crestal line portion J2.That is, as described above, by setting curvature small in inner peripheral edge portion
In the above-mentioned end edge portion 24a3 ' of the curvature of main part 24a2 ', the tg ' of contact site as shown expands like that, so as to make a left side
Right crestal line portion J2 and its contact condition of neighbouring position and the outer circumferential surface of leading edge portion 11 is changed into face from line contact condition and connects
The state of touching.Therefore, in addition to the above-described effects, additionally it is possible to the damage of the outer circumferential surface of engagement pawl 24 ' and insert port 10a is reduced, from
And improve durability.
Finally, when from the above-mentioned interstage further by insert port 10a insertions receiving port 20a when, leading edge portion 11
The main part 24a2 ' and left and right end edge portion 24a3 ' of the inner peripheral edge portion than engagement pawl 24 ' are moved to closer to the position of inner side
Place is put, so that the path sidepiece of the main part 24a2 ' of inner peripheral edge portion and left and right end edge portion 24a3 ' and periphery end difference 12
Divide 12a opposite.Thus, engagement pawl 24 ' is prominent under the action of the elastic force of spring members 25, thus the snap-latch surface of engagement pawl 24 '
24b ' engages with periphery end difference 12, is changed into connection status (completing the stage).
As described above, in the present embodiment, the regulation area for tilting face 24a1 ' of the inner peripheral surface 24a ' of engagement pawl 24 '
The curvature in domain is less than existing curvature (that is, radius of curvature R a is more than D/2=32.25mm (when nominal diameter is 65mm)).Thus,
In the initial stage of attended operation, the suffered power of engagement pawl 24 ' is not easy to put on circumferencial direction.Therefore, it is possible to avoid occurring
The state of affairs that engagement pawl 24 ' is blocked and can not acted in the opening 26a of pawl seat 26 ' etc., so as to make engagement pawl 24 ' swimmingly
Acted into traveling out.In addition, in the initial stage of attended operation, compared with the point contact state in existing structure, insert port
