In the conventional hairspring with conventional resistance to shake Bearning mechanism 101F, the 101R formed possessing as more than
In the conventional clock and watch 102 of escapement 103, such as Figure 13(a)With(b)As showing, appropriate shape is in hair-spring balance 103
In the case of state PS0, clock and watch 102 carry out appropriate action.That is, by the resistance to Bearning mechanism 101F that shakes of bottom side and dial plate side,
101R and endstone 110F, 110R of mechanism 101F, 101R are configured to make putting down for endstone 110F, 110R
Tenon bearing plane 111F, 111R of planar is vertical relative to the central axis C of balance staff 140 and the central axis C of balance staff 140 is actual
On it is not inclined in the case of, no matter take the resistance to Bearning mechanism 101F that shakes of bottom side to be located at the resistance to Bearning mechanism 101R that shakes of dial plate side
Top keep flat posture PP1, still take the resistance to Bearning mechanism 101R that shakes of dial plate side to be located at the resistance to Bearning mechanism that shakes of bottom side
The upset of 101F top keeps flat posture PP2, and balance staff 140 is all in position C0R, C0F and the dial plate side on the downside of it or bottom
Resistance to shake Bearning mechanism 101R, 101F of side endstone 110R, 110F tenon bearing plane 111R, 111F abut, and with
Rotated centered on the position C0R, C0F, described position C0R, C0F be positioned at downside tenon portion 141R, 141F end face 145R,
The position actually by central axis C in 145F.Therefore, posture PP1, PP2 regardless of clock and watch 102, hair-spring balance
103 actually can similarly be acted, and posture difference can be suppressed into bottom line.
But with the conventional of the conventional hair-spring balance 103 for possessing conventional resistance to shake Bearning mechanism 101F, 101R
Clock and watch 102 in, be located at the resistance to Bearning mechanism that shakes of dial plate side in the resistance to Bearning mechanism 101F that shakes that clock and watch 102 are configured to bottom side
Direction on 101R is posture(Hereinafter referred to as " keep flat posture ")The resistance to axle that shakes of dial plate side is configured to during PP1 and by clock and watch 102
Hold the direction i.e. posture that mechanism 101R is located on the resistance to Bearning mechanism 101F that shakes of bottom side(Hereinafter referred to as " upset keeps flat appearance
Gesture ")During PP2, there may be different situations for the state of hair-spring balance 103.
For example, such as Figure 14(a)With(b)It is shown, the endstone in the side of hair-spring balance clamping plate 105 or bottom side
110F is with a little(Such as 1 degree or so)Inclined state is installed on hole jewel bearing frame 120F state by stage clip 137F
Under PS1, as Figure 14(a)The resistance to Bearning mechanism 101F that shakes that clock and watch 102 are configured to bottom side as showing is located at dial plate
On the resistance to Bearning mechanism 101R that shakes of side when keeping flat posture PP1 and as Figure 14(b)Clock and watch 102 are configured as showing
Posture PP2 is kept flat for the resistance to Bearning mechanism 101R that shakes of the dial plate side upsets being located on the resistance to Bearning mechanism 101F that shakes of bottom side
When, the state of hair-spring balance 103 turns into different situations.Also, for endstone 110F inclination, it is typical that
Result from hole jewel bearing frame 120F relative to the resistance to pedestal 130F that shakes it is inclined in the case of.
In the feelings in the state PS1 for being obliquely mounted with the endstone 110F of the side of hair-spring balance clamping plate 105
Under condition, such as Figure 14(a)The resistance to Bearning mechanism 101R that shakes of dial plate side as showing is located at downside and the thrust of dial plate side is precious
Stone bearing 110R bears the keeping flat in posture PP1 of the tenon 141R of balance staff 140 end face by its tenon bearing plane 111R, with Figure 13
's(a)With(b)Situation actually, balance staff 140 is in position C0R and the resistance to Bearning mechanism that shakes of the dial plate side on the downside of it
101R endstone 110R tenon bearing plane 111R is abutted, and is rotated centered on the C0R of the position, the position C0R
It is the position actually by central axis C in the tenon portion 141R of downside end face 145R.
On the other hand, clock and watch 102 are overturn, such as Figure 14(b)The side of hair-spring balance clamping plate 105 as showing(Bottom
Side)The resistance to Bearning mechanism 101F that shakes be located at downside and the endstone 110F of the side of hair-spring balance clamping plate 105 is held by its tenon
Born by face 111F in the posture PP2 of the tenon 141F of balance staff 140 end face, with Figure 13's(a)With(b)Situation and Figure 14
's(a)Situation it is different, balance staff 140 leaves central axis C, and in ora terminalis CaF and the hair-spring balance clamping plate 105 on the downside of it
The resistance to Bearning mechanism 101F that shakes of side endstone 110F tenon bearing plane 111F is abutted, and the ora terminalis CaF is under being located at
The ora terminalis of the side consistent with the incline direction of endstone 110 in the tenon portion 141F of side end face 145F.Therefore, put
The pivot CaF of axle 140 is different from the central axis C of the balance staff 140, and the pivot CaF of balance staff 140 is from the central shaft
Line C leaves △ pr(Equivalent to the size of the radius of tenon portion 141, several 10 μm or so)Point CaF(Ca), rotary shaft is simultaneously unstable.
Therefore, in the case of in state PS1, clock and watch 102 take keep flat posture PP1 when and take upset to keep flat
During posture PP2, the action of hair-spring balance 103 is different, it is difficult to avoids producing the difference of considerable degree of step number.
In addition, such as Figure 15(a)With(b)(Particularly Figure 15's(b))It is shown, such as in upset keeps flat posture PP2,
Under the inclined situation PS2 of central axis C of balance staff 140, also with Figure 14's(a)With(b)Situation PS1 it is the same, balance staff 140 is therefrom
Mandrel line C leaves, and stopping in the ora terminalis CaF and resistance to Bearning mechanism 101F that shakes of the side of hair-spring balance clamping plate 105 on the downside of it
The tenon bearing plane 111F for pushing away jewel bearing 110F is abutted, and the ora terminalis CaF is in the tenon portion 141F of downside end face 145F
The central axis C with balance staff 140 the consistent side of incline direction ora terminalis.Therefore, the pivot CaF of balance staff 140 with
The central axis C of the balance staff 140 is different, and the pivot CaF of balance staff 140 is to leave △ pr from central axis C(Equivalent to tenon
The size of the radius in portion 141, several 10 μm or so)Point CaF(Ca), rotary shaft is simultaneously unstable.
In the case of in state PS2, clock and watch 102 take keep flat posture PP1 when and take upset to keep flat
During posture PP2, the action of hair-spring balance 103 is also different, it is difficult to avoids producing the difference of considerable degree of step number.
In addition, the circumferential weight that the central axis C of balance staff 140 inclination can for example result from escapement 150 is uneven
In the case of.Also, strictly speaking, for example, the form for volute spring hairspring 155 tighten action or release act when,
Moment of torsion is applied with to balance staff 140 via hairspring inside stud 143, correspondingly, the central axis C of balance staff 140 can be more or less
Tilt, or the inclination can more or less change.
In addition, such as Figure 16(a)With(b)It is shown, the side of hair-spring balance clamping plate 105 tenon 141F end face 145F relative to
In the case of the inclined state PS3 of central axis C of balance staff 140, in upset keeps flat posture PP2, in the 145F of end face with
Tilt and the prominent ora terminalis CaF and resistance to Bearning mechanism 101F that shakes of the side of hair-spring balance clamping plate 105 on the downside of it thrust treasured
Stone bearing 110F tenon bearing plane 111F is abutted.Therefore, the pivot CaF of balance staff 140 and the balance staff 140 central axis C
Difference, the pivot CaF of balance staff 140 are to leave △ pr from central axis C(It is several equivalent to the size of the radius of tenon portion 141
10 μm or so)Point CaF(Ca), rotary shaft is simultaneously unstable.
In the case of in state PS3, clock and watch 102 take keep flat posture PP1 when and take upset to keep flat
During posture PP2, the action of hair-spring balance 103 is also different, it is difficult to avoids producing the difference of considerable degree of step number.
On the other hand, it is also proposed that following scheme:Tenon 141F, 141R of balance staff 140 end face 145F, 145R are not made turn into
It is plane, but instead of so that the end face or tenon 145F, 145R bend to convex, keep flat appearance to avoid taking in clock and watch 102
During gesture PP1 and take upset made when keeping flat posture PP2 due to various reasons as described above step number produce difference possibility
Improve.
But tenon 141F, 141R diameter are usually up to 0.1mm or so, therefore, it is difficult to keep convex curvature higher
The dimensional accuracy of the shape in face, if the deviation of tenon length be the length of balance staff 140 deviation it is inclined with the shape in convex curvature face
Difference and increase, then keep flat posture PP1 and upset keep flat hairspring 155 in posture PP2 shape generation difference possibility increase.
Therefore, the hairspring 155 that should extend originally in plane inside vortex shape vertical the central axis C relative to balance staff 140 is for example
More or less turn into funnel-form, its spring performance when when clock and watch are in and keep flat posture PP1 or keeping flat posture PP2 in upset
Change, it is difficult to which the possibility for avoiding producing step number difference increases.

With possess the resistance to Bearning mechanism 1F that shakes as preferable one embodiment of the invention for forming as above,
The mechanical clock of preferable one embodiment of the invention of the hair-spring balance 3 of 1R preferable one embodiment of the invention
In 2, reference picture 4(a)With(b), Fig. 5(a)With(b)And Fig. 6(a)With(b), under various conditions, by clock and watch 2
The resistance to Bearning mechanism 1F that shakes for being configured to bottom side is located at the feelings of " keeping flat posture " P1 on the resistance to Bearning mechanism 1R that shakes of dial plate side
Condition and by clock and watch 2 be configured to dial plate side the resistance to Bearning mechanism 1R that shakes be located on the resistance to Bearning mechanism 1F that shakes of bottom side " upset
Keeping flat posture " degree of the presence or absence of difference between P2 situation or difference is described in detail.
The central axis C that the balance staff 40 actually relative to hair-spring balance 3 is configured in endstone 10F, 10R hangs down
Directly and bearing plane 11F, 11R of spherical calotte shape is in the case of the state of central axis C rotational symmetry, is adopted in clock and watch 2
When making even when putting posture P1 and take the upset keep flat posture P2, the bearing state of the balance staff 40 of hair-spring balance 3 is practically identical, because
This, as in the past the same, in the case where keeping flat posture P1 and overturning and keeping flat posture P2, the difference of step number actually and is not present.Also,
In the hair-spring balance 3, endstone 10F, 10R tenon bearing plane 11F, 11R is spherical calotte shape, therefore the tenon bearing plane
11F, 11R are actually abutted relative to end face 45F, 45R of tenon portion 41F, 41R of balance staff 40 with a bit, therefore, the rotation of balance staff 40
Turn easily stable.
Such as Fig. 4(a)With(b)It is shown, in the endstone 10F of the side of hair-spring balance clamping plate 5 or bottom side with a little
(Such as 1 degree or so)Inclined state is installed on by stage clip 37F under hole jewel bearing frame 20F state S1, strictly speaking,
Such as Fig. 4(a)Clock and watch 2 are taken when keeping flat posture P1 and such as Fig. 4 as showing(b)Clock and watch 2, which are taken, as showing turns over
When turning to keep flat posture P2, the state of hair-spring balance 3 is more or less to have some different situations.For endstone 10F
Inclination, the inclination in inclined plane 26a, 26b relative to the resistance to pedestal 30F that shakes in hole jewel bearing frame 20F typically occurs
Face 35a, 35b skew so as to relative to the resistance to pedestal 30F that shakes it is inclined in the case of.Also, this situation(Taken in clock and watch and keep flat appearance
It is different with the state of hair-spring balance when taking the upset to keep flat posture during gesture)Itself is with contacting Figure 14's(a)With(b)To with possessing
One when the conventional clock and watch 102 of conventional resistance to shake Bearning mechanism 101F, 101R conventional hair-spring balance 103 illustrate
Sample, but the degree of the difference of the state of hair-spring balance when keeping flat posture and when upset keeps flat posture is in clock and watch 2 and conventional clock
It is different in table 102.
That is, in clock and watch 2, in the shape for being obliquely mounted with the endstone 10F of the side of hair-spring balance clamping plate 5
In the case of state S1, such as Fig. 4(a)As showing, dial plate side the resistance to Bearning mechanism 1R that shakes is located at downside and dial plate side
The endstone 10R tenon 41R that bear by its tenon bearing plane 11R balance staff 40 end face 45R keep flat in posture P1, put
Spherical calotte of the axle 40 in position C0R and the resistance to Bearning mechanism 1R that shakes of the dial plate side on the downside of it endstone 10R
The tenon bearing plane 11R of shape is abutted, and is rotated centered on abutted position C0R around central axis C, and the position C0R is to be located at
The position by central axis C in the tenon portion 41R of downside end face 45R, this situation and Figure 14's(a)Situation actually phase
Together.I.e., within the range, be not in due to by stage clip 37F by the end stone axle of the side of hair-spring balance clamping plate 5 or bottom side
10F is held with a little(Such as 1 degree or so)Inclined state is installed on hole jewel bearing frame 20F and caused influence, this and figure
14(a)Situation be practically identical.But strictly speaking, endstone 10R tenon is born in the clock and watch 2
Face 11R bends to convex, therefore, the position C0R consistent with central axis C reliably turn into pivot on this point and clock
Table 102 has differences.
On the other hand, clock and watch 2 are overturn, such as Fig. 4(b)As the showing, side of hair-spring balance clamping plate 5(Bottom side)
The resistance to Bearning mechanism 1F that shakes be located at downside and the endstone 10F of the side of hair-spring balance clamping plate 5 is held by its tenon bearing plane 11F
Kept flat by the tenon 41F of balance staff 40 end face 45F upset in posture P2, even if the tenon bearing plane 11F near central axis C
Profile produces skew somewhat, and tenon bearing plane 11F profile is also like Fig. 4's(b)In be shown in phantom line as with produce 1
It is much the same before spending the inclination of left and right.Especially, with endstone 10F substantially 1 inclination spent, tenon bearing plane
The position that tangent line in 11F intersects with central axis C relative to vertical central axis C position CaV and bearing plane 11F is substantially
Unanimously.That is, when because hole jewel bearing frame 20F is relative to the skew of the resistance to pedestal 30 that shakes(Face 26a, 26b relative to face 35a,
35b skew)And when producing endstone 10F inclination, even if tenon bearing plane 11F with 1 degree of rotation correspondingly big
Cause rotates in a circumferential direction 1 degree, and the direction of the section for the position C0F that can also make with central axis C to intersect in tenon bearing plane 11F keeps big
Cause to fix, therefore, as a result, section in tenon bearing plane 11F relative to position CaV vertical central axis C hardly from
The position C0F skews that bearing plane 11F intersects with central axis C.Therefore, dial plate of the balance staff 40 at point CaV with being located on the downside of it
The tenon bearing plane 11F of the resistance to Bearning mechanism 1F that shakes of side endstone 10F spherical calotte shape is abutted, and with the position
Rotated centered on CaV around central axis C, the point CaV is to pass through central shaft in the tenon portion 41F of downside end face 45F
Point near line C position.Also, even if flange connector shape portions 25 of the tenon bearing plane 11F along hole jewel bearing frame 20F
Circular cone shape inner surface 25a skew, situation is also identical.
That is, in the mechanical clock 2 with hair-spring balance 3, the hair-spring balance 3 possesses resistance to shake Bearning mechanism 1F, 1R,
Resistance to shake Bearning mechanism 1F, the 1R possess convex curvature tenon bearing plane 11F, 11R of part spherical, such as Fig. 4(a)With(b)It is shown,
By stage clip 37F by the endstone 10F of the side of hair-spring balance clamping plate 5 or bottom side with a little(Such as 1 degree or so)Incline
Oblique state is installed in hole jewel bearing frame 20F state S1, such as Fig. 4(a)Clock and watch 2, which are taken, as shown keeps flat
During posture P1 and such as Fig. 4(b)When clock and watch 2 as shown take the upset to keep flat posture P2, strictly speaking, hair-spring balance 3
State is more or less different situation, but in fact, in the case of taking upset to keep flat posture P2, the resistance to axle that shakes
Hold the position that the convex curvature tenon bearing plane 11F of mechanism 1F part spherical abuts with the tenon portion 41F of balance staff 40 end face 45F
Position CaV on approximate centre axis C.Therefore, in keeping flat posture P1 and upset keeps flat posture P2, hair-spring balance 3 is real
Can equally it be acted on border, diversity ratio Figure 14's of step number(a)With(b)Situation it is much smaller.
On the other hand, such as Fig. 5(a)With(b)(Particularly Fig. 5's(b))It is shown, in upset keeps flat posture P2, putting
The central axis C of axle 40 is somewhat(Such as 0.2 degree or so)Under inclined situation S2, the tenon portion 41F of balance staff 40 end face 45F from
The position Cb of the central axis C of balance staff 40 slightly away and the resistance to Bearning mechanism that shakes of the side of hair-spring balance clamping plate 5 on the downside of it
1F endstone 10F tenon bearing plane 11F is abutted.Herein, position Cb is held equivalent to endstone 10F tenon
By the face 11F section position parallel with the tenon portion 41F of balance staff 40 end face 45F(Position that can be consistent), the balance staff 40
With inclined central axis C.
Therefore, the pivot Cb of balance staff 40 and the central axis C of the balance staff 40 are different, the pivot Cb positions of balance staff 40
In leaving △ r from the position that central axis C is passed through(The part of the radius of tenon portion 41,10 μm or so)Position, pendulum
Axle 40 is rotated centered on point Cb.
In the case of in state S2, when when clock and watch 2 are taken and keep flat posture P1 and taking upset to keep flat posture P2,
The action of hair-spring balance 3 is actually distinct, it is difficult to avoids producing the difference of small step number.But upset is taken to keep flat posture P2
When center Cb from center C skew for balance staff 40 tenon portion 41 radius part left and right, at this point, with
Produce the skew of the radial extents of the tenon portion 41 of balance staff 40(Figure 15's(b))Conventional clock and watch 102 compare, can significantly subtract
Few upset keeps flat posture P2 and keeps flat the difference of the step number between posture P1.
In addition, the central axis C of balance staff 40 inclination has a variety of causes.That is, inclination is produced in the central axis C of balance staff 40
In the case of phenomenon, no matter the posture of clock and watch 2, compared with conventional clock and watch 102, it is larger that step number generation can be reduced
The worry of difference.As such example, such as there are weight imbalance, the 50 inclined situation of escapement of escapement 50.It is also, strict
Ground says, for example, when the vortex in hairspring 55 is tightened or unclamped, due to acting on balance staff from hairspring 55 via hairspring inside stud 43
40 power, the central axis C of balance staff 40 axle may also be tilted more or less.Even if in this case, in balance staff 40
Both ends possess in the hair-spring balance 3 of the resistance to Bearning mechanism 1,1 that shakes, with the tenon bearing plane 111 as conventional hair-spring balance 103
Different for the situation of plane, tenon bearing plane 11 is spherical calotte, is not the lateral margin of the end face 45 of the tenon portion 41 of balance staff 40 therefore,
But the position of inclined section corresponding with tenon bearing plane 11 is capable of at the position near the central axis C in the end face 45
Abut.Therefore, it is possible to which the center of the rotation of balance staff 40 is suppressed into bottom line from the central axis C degree offset.
In addition, such as Fig. 6(a)With(b)It is shown, the side of hair-spring balance clamping plate 5 tenon 41F end face 45F relative to balance staff
Under the 40 inclined state S3 of central axis C, in upset keeps flat posture P2, inclined end face 45F is precious in position Cd and thrust
Stone bearing 10F tenon bearing plane 11F is abutted, and the thrust that position Cd is the resistance to Bearning mechanism 1F that shakes of the side of hair-spring balance clamping plate 5 is precious

That is, in the case of in state S3, when clock and watch 2 are taken and keep flat posture P1 and upset is taken to keep flat appearance
During gesture P2, the action of hair-spring balance 3 is also different, but its difference and Fig. 5(a)With(b)Situation it is the same, with Figure 16's(a)
With(b)The conventional clock and watch 102 shown are compared, and can significantly be reduced upset and be kept flat posture P2 and keep flat the step between posture P1
Several difference.
Therefore, the pivot Cd of balance staff 40 and the central axis C of the balance staff 40 are different, and balance staff 40 is with from the central axis
C leaves about △ r(The part of the radius of tenon portion 41,10 μm or so)Point Cd centered on rotate.
In addition, as more than, in clock and watch 2, the bearing plane 11 of endstone 10 is formed as part spherical, because
Even if this have it is various tilt etc., the offset that pivot is offset from the center C of balance staff 40 also very little, therefore can will be by keeping flat
The variation that posture P1 and upset keep flat the step number of clock and watch 2 caused by posture P2 etc. posture is suppressed to bottom line.
In addition, in the clock and watch 2, the part that is formed as part spherical is the tenon bearing plane 11F of endstone 10,
11R, rather than end face 45F, 45R of tenon portion 41F, 41R of balance staff 40, and the spherical calotte is relatively large in diameter, therefore balance staff 40
Length and the possibility that significantly changes of other amount it is also smaller.

Improve endstone 10A dimensional accuracy.Also, in the hair-spring balance 3A resistance to bearing structure 1A that shakes, end stone
Bearing 10A is made up of spheroid 13, therefore the size increase of clock and watch 2A thickness direction, therefore the resistance to pedestal 30A that shakes is except with axle
Outside the large diameter tubular portion 32A this point bigger than the large diameter tubular portion 32 of the resistance to pedestal 30 that shakes to length, with the resistance to pedestal 30 that shakes
It is actually same structure.
In addition, in the resistance to bearing structure 1A that shakes, endstone 10A is made up of spheroid 13, clock and watch 2A thickness side
To size increase, it is therefore, different from the situation of the resistance to bearing structure 1 that shakes, endstone 10A it is axial be not by through hole
Jewel bearing frame 20A is supported, but is supported by hole jewel bearing 17A.Therefore, hole jewel bearing 17A end face 17dA into
For the circular cone shape face in the spherical face 14 for bearing endstone 10A.In endstone 10A with through hole jewel axle
Holding the inner side of the annular section of the spherical facial 14 of 17A circular cone shape end face 17dA abuttings turns into tenon bearing plane 11A.
In addition, stage clip 37A is engaged by outer circumferential side holding section 38a, 38a, 38a with the resistance to pedestal 30A that shakes holding section 36, lead to
Area pressed 12A is carried out in the U-shaped holding section 39,39,39 for crossing inner circumferential side, and region 12A is located at the end stone of the form of spheroid 13
In bearing 10A with tenon bearing plane 11A in diametrically opposed side.
For hole jewel bearing frame 20A, as long as being conceived to outer circumferential surface section, its be exactly with hole jewel bearing frame 20 substantially
Identical structure, the hole jewel bearing frame 20A have:Periphery minor diameter cylindrical portion corresponding with minor diameter cylindrical portion 21
21A, periphery large diameter tubular portion 22A corresponding with large diameter tubular portion 22 and by they connect and flange connector
Profile circular cone shape flange connector shape portion 25A etc. corresponding to shape portion 25.But it is different from endstone 10, in order to suppress
Thickness, endstone 10A are made up of the spheroid 13 of minor diameter, thus endstone 10A configuration with through hole jewel
In tubular inner peripheral surface 27 roughly the same bearing bracket stand 20A tubular inner peripheral surface 21a.Also, the tubular inner peripheral surface 27 is that periphery is big
Diameter cylindrical portion 22A inner peripheral surface.
