The lower half of above-mentioned movable part 3 in fig. 2, movable part 3 width ( Terminal block column direction and be the direction at a right angle with the paper in Fig. 2) on the first terminal 20, Second terminal 30 and the position of fixture 40 correspondence, be front and back formed through and allowed the first terminal 20, the second terminal 30 and respective first pressing arm 21, second press arm of fixture 40 52, the second groove portion of first groove portion of the slit-shaped that portion 31, the respective front portion of upper arm parts 41 enter 53 and the 3rd groove portion 54.Thus, the 52, second groove portion of above-mentioned first groove portion 53 and the 3rd groove Groove width (groove inner surface direction at a right angle with the paper width each other) shape in portion 54 Become more slightly larger than the respective thickness of slab of above-mentioned the first terminal the 20, second terminal 30 and fixture 40 Size.In the 52, second groove portion of above-mentioned first groove portion 53 and the 3rd groove portion 54, it is respectively provided with Have first cam part the 55, second cam part 56 and together connected to each other for groove inner surface Three cam part 57.

From (A) of Fig. 2 it can be seen that be arranged on terminal block column direction and the first terminal 20 First cam part 55 in the first corresponding groove portion 52 is positioned at the above-mentioned of the movable part 3 of open position The bottom in the first groove portion 52, and be formed as around 3/4 perimembranous of center of rotation be divided into circle, remaining Bottom right 1/4 perimembranous be divided into the shape in foursquare corner.In the rotation of this first cam part 55 On the extended line of the rotational axis x that the heart is positioned at movable part 3.By the rotation of movable part 3, Making the elastic displacement of the first pressurized arm 24 of the first terminal 20, thus this center of rotation moves up and down, But limited by the edge before and after concave first compression zone 24A in the lateral direction and do not move. The direction of the elastic displacement of above-mentioned first pressurized arm 24 is to be extended with this first pressurized arm 24 Direction at a right angle, direction, therefore the top of the first cam part 55 is supported with the first compression zone 24A The first abutment connect moves at above-mentioned above-below direction, links this first abutment and above-mentioned rotary shaft The neutral line Z of line X is vertically extending and at a right angle with fore-and-aft direction.Above-mentioned first convex The slidably contacting section rotated in concave above-mentioned first compression zone 24A in wheel portion 55 (is positioned at Compare by the horizontal line of rotational axis x upper section by the top with compare the neutral line Z side of keeping left The section below of position) be formed as circular portion, therefore its radius is cam radius.Therefore, For this first cam part 55, when movable part 3 turns to the pass of Fig. 4 from the open position of Fig. 2 During closed position, the first cam part 55 is only formed as above-mentioned 3/4 circumferential portion and first of circular portion The boundary slip contact of compression zone 24A, the cam radius at this slidably contacting section is constant, therefore, In this first cam part 55, only do not produce cam displacement.

Interval which till no matter movable part 3 is positioned at from open position to closed position rotates Position, above-mentioned first cam part 55 also will not be with the front portion of the first supporting arm 22 of the first terminal Upper limb contact, but mutually leave and be positioned at compare this first supporting arm 22 position by the top.

As long as above-mentioned first cam part 55 can be along with the rotation of movable part 3 by concave One compression zone 24A guides and rotates and be sufficient for, as it can be seen, slide with the first compression zone 24A Contact and directed part can be formed as circular portion, it is also possible to be formed as non-circular not Other shapes Deng radius.Now, even if non-circular cam face, the first cam part 55 Rotational axis x the most only move up and down on neutral line Z, by concave first compression zone 24A The edge of both sides limits without moving along transverse direction.

On the other hand, from (B) of Fig. 2 it can be seen that be arranged on terminal block column direction with Second the comparing of cam part 56 in the second groove portion 53 of the second terminal 30 correspondence passes through pivot center The horizontal line of X by the top and compare the neutral line Z side of keeping left part formed arc-shaped epirelief wheel face 56A, has substantially fan type portion relative to this epirelief wheel face 56A on right side, and in this scallop Forming lower cam surface 56B, center of rotation is positioned at consistent with the center of rotation of the first cam part 55 The position of rotational axis x.Epirelief wheel face 56A is formed as comparing the first cam being shown in broken lines The cam surface that the arc-shaped part in portion 55 highlights towards radius foreign side.Form above-mentioned lower cam surface 56B Scallop have in (B) of Fig. 2 from the right end position of above-mentioned epirelief wheel face 56A towards right Extend upper extension and extend obliquely towards lower right from the lower end position of epirelief wheel face 56A Lower extension, front lower by what the front end from above-mentioned upper extension was the most linearly extended Cam surface 56B-1 and from the front end of lower extension linearly extend towards right rear under convex Under the centre of wheel face 56B-2 arc-shaped, cam surface 56B-3 links and forms lower cam surface 56B.Whether which position of rotational axis x and above-mentioned lower cam surface 56B is linked, should be away from Cam radius from the most above-mentioned epirelief wheel face 56A.Further, for linking above-mentioned pivot center X and front lower cam surface 56B-1, rear lower cam surface 56B-2 and middle lower cam surface 56B- Each the distance of 3 that is the size of cam radius, under centre, cam surface 56B-3 is maximum, Secondly, diminish according to the order of front lower cam surface 56B-1 and rear lower cam surface 56B-2.

Illustrating that movable part 3 is positioned in (B) of Fig. 2 of the state of open position, second is convex The epirelief wheel face 56A in wheel portion 56 is positioned at and compares the second compression zone 34A of the second terminal 30 and keep left Side and from this second compression zone 34A position slightly away, the rear lower cam of lower cam surface 56B Face 56B-2 is solid with before the second of the front portion of the second supporting arm 32 as the second terminal 30 The cam support 38 that the upper limb in arms portion 36 is formed contacts.Thus, as lower cam surface 56B Second time of the position abutted with above-mentioned cam support 38 abutting contact along with movable part 3 from Open position rotates towards closed position, according to above-mentioned rear lower cam surface 56B-2, middle lower cam Face 56B-3, the order of front lower cam surface 56B-1 be positioned at their region and this position from Rear is moved forward.

From (C) of Fig. 2 it can be seen that be arranged at fixture 40 correspondence on terminal block column direction The 3rd cam part 57 in the 3rd groove portion 54 be fabricated to and be positioned at above-mentioned the of the second groove portion 53 Two cam part 56 same shapes, have the scallop stretched out towards right side, center of rotation position In the rotational axis x consistent with the center of rotation of the first cam part 55 and the second cam part 56 Position.The difference of above-mentioned 3rd cam part 57 and the second cam part 56 is: the 3rd cam part In the lower cam surface of 57 and the second cam part 56 rear lower cam surface 56B-2 and centre Lower part suitable for cam surface 56B-3 be positioned in (C) of Fig. 2 and (C) of Fig. 3 from The lower arm part 42 of fixture 40 positions away from, does not contacts with this lower arm part 42.Thus, this Kind of the 3rd cam part 57 when movable part 3 is positioned at open position and rotation process position not with Above-mentioned lower arm part 42 contacts, when movable part 3 arrives closed position, and can from (C) of Fig. 4 To find out, the front lower cam surface 56B-1 of the 3rd cam part 57 contacts with above-mentioned lower arm part 42.

The adapter of the present embodiment of such structure is used concurrently according to following main points Wave function.

First, adapter 1 is configured at the assigned position on circuit substrate (not shown), by Second connecting portion 39 of first connecting portion the 29, second terminal 30 of one terminal 20, fixture 40 The respective corresponding portion soldering of soldering fixed part 49 and circuit substrate connect and be fixed.

For being installed on the adapter 1 of circuit substrate by this way, by movable part 3 such as Fig. 2 As shown in be arranged at the open position erected, make the receiving peristome 16 of housing 10 be formed as court The state of rear (left in figure) opening, is formed as being inserted into the state of strap F.

Secondly, when movable part 3 is positioned at open position as shown in Figure 2, by flat The coupling part of flush conductor F is inserted in above-mentioned receiving peristome 16 forward.The first terminal 20 The first press section 25A of the first flexible arm 25 support with the first of the first rear support arm 27 Between portion 27A, the second press section 35A of the second flexible arm 35 of the second terminal 30 and the All become between the second support 37A-1 of two flexible support arm 37A and compare strap F The slightly wider interval of the thickness of above-mentioned coupling part, therefore, the connecting portion partial volume of this strap F Easily insert.But, about above-mentioned fixing piece 40, the fastener of the upper arm parts 41 of this fixture 40 The connecting portion of above-mentioned strap F compared with becoming between 45A and the fastener 49A of lower arm part 42 Point the narrow interval of thickness, therefore, strap F is by making above-mentioned locking with its front end The displacement of portion 45A elasticity and fastener 45A is lifted thus widen above-mentioned interval and advance on one side advise After location is put, above-mentioned fastener 45A enters the engaged part F3 of the incision-like of strap F, Thus, strap F is temporarily held.

Even if the coupling part of strap F is inserted in the above described manner, due to above-mentioned movable part 3 It is positioned at open position, therefore supports the latter half of of arm 22 constitute the first terminal 20 first The teat 27B that the lower edge of the first rear support arm 27 is formed is still located at the diapire 15 from housing 10 Position away from and form clearance C.

Secondly, as see from Fig. 3 and Fig. 4, make movable part 3 via Fig. 3's The position being in rotation process turns to the closed position of Fig. 4.It addition, at Fig. 3 and Fig. 4 In, originally should illustrate when being inserted with strap, but for easy to understand the One terminal the 20, second terminal 30 and fixture 40 at utmost can elastic addendum modification, it is shown that There is not Bitwise during strap, but actually strap is inserted into and exists, therefore, When identical with (B) of Fig. 5, elastic addendum modification stops at and decreases strap The amount of thickness, produce with above-mentioned at utmost can the suitable contact pressure of the difference of elastic addendum modification. By the rotation of above-mentioned movable part 3, first cam part the 55, second cam part of movable part 3 56 and the 3rd cam part 57 rotate centered by center of rotation X.Turning shown in Fig. 3 During Dong, the first cam part 55 and the 3rd cam part 57 are respectively at from the first terminal 20 First before fix the state that the anterior upper limb of arm 26 and lower arm part 42 leaves, but from Fig. 3 (B) it can be seen that the second cam part 56 lower cam surface 56B with the second terminal 30 The position of second time abutment that cam support 38 abuts is from the rear lower cam surface of (B) of Fig. 2 56B-2 is transitioned into cam surface 56B-3 under the centre of this lower cam surface 56B.Due to cam radius Under centre, cam surface 56B-3 is maximum, and therefore, second time abutment is from rear lower cam surface 56B -2 are transitioned into cam surface 56B-3 under centre, and, the epirelief wheel face 56A of the second cam 56 Utilize its on second abutment make the elastic displacement of the second pressurized arm 34 of the second terminal 30 and by the Two pressurized arms 34 lift upward.Although the position of second time abutment supports at above-mentioned cam Move towards the rear from front on the upper limb in portion 38, but owing to this upper limb is the most horizontal-extending, The most do not change.Thus, owing to the cam radius at second time abutment exists Maximum at cam surface 56B-3 under above-mentioned centre, therefore, the position court of the rotational axis x of cam The amount of the increment of top translating cam radius.Due to the first cam part 55 and the 3rd cam part 57 Center of rotation be all located at the position on rotational axis x too, therefore the first cam part 55 with And the 3rd cam part 57 the most all rotate while its center of rotation rises, and by its upper surface By first pressurized arm 24 and the fixture being formed with the first compression zone 24A of the first terminal 20 The front portion of the upper arm parts 41 of 40 is lifted.So, rotated towards closed position by movable part 3, First cam part the 55, second cam part formed as one as a part for movable part 3 56 and the 3rd cam part 57 rotate, thus, the first pressurized arm 24 of the first terminal 20, Second pressurized arm 34 of the second terminal 30 and the anterior difference of the upper arm parts 41 of fixture 40 It is lifted, by lever principle, flexible arm the 25, second terminal 30 of the first of the first terminal 20 The second flexible arm 35 and the rear portion of upper arm parts 41 of fixture 40 the most elastic Displacement, and maintain its position.Thus, the first terminal 20 utilizes the first of the first flexible arm 25 Press section 25A, the second terminal 30 utilize the second press section 35A of the second flexible arm 35 respectively Pressing strap F downward and make it bend, this strap F self-forming from below is in first First support 27A of the first rear support arm 27 of terminal 20 and be formed at the second terminal 30 The second support 37A-1 of the second flexible support arm 37A be supported by by counter-force.Though First rear support arm 27 elastic deflection downward displacement of right above-mentioned the first terminal 20, but at this The rear end lower edge of the first rear support arm 27 is formed with teat 27B prominent downward, works as activity When parts 3 turn to closed position, the upper surface of the diapire 15 of above-mentioned teat 27B and housing 10 Abut and stop the first rear support arm 27 to produce the displacement of further elastic deflection, make maximum change Position is constant, and, by from the counter-force of diapire 15, make above-mentioned first support 27A and the The clamping force to strap F between one press section 25A is reliable and is allowed to strength.

Further, by the first press section 25A and second pressing of the second terminal 30 of the first terminal 20 Portion 35A press downward and decline the engaged part F3 of the incision-like of the strap F of movement with The fastener 49A locking of the lower arm part 42 of fixture 40, utilizes close in the way of the most opposed Two fastener 45A and 49A arranged prevent strap F from deviating from.

Therefore, in the present embodiment, strap F is connected with adapter 1, but to being formed at The teat 27B of the first rear support arm 27 of the first terminal 20 of the adapter 1 of present embodiment And the first cam part 55 of movable part 3 and the second cam part 56 are described in detail.

The teat ＞ of ＜ the first terminal

In the electrical connector for flat conductive member of the form of present embodiment, keep the thickness of slab of metallic plate Tabular surface and make, thus, by being terminal block column direction by this thickness of slab direction setting, Can be with the high multiple terminal of density array.Further, due to formed high-density array and terminal that Distance around here is little, therefore, becomes at least make connecting portion connect relative to the soldering of circuit substrate Obtain easily, two kinds of terminals are alternately arranged and connecting portion is arranged in the longitudinal direction housing Outer different position, increases connecting portion terminal block column direction interval to each other.So, when many When individual different types of terminal is arranged in broad range on the width of strap, most feelings Under condition uneven in the rigidity of this width upper shell and the flexure of strap.Moreover, when The dimensional discrepancy that causes because of scale error when manufacturing to each other at terminal, relative to the group of housing When assembling position error during dress etc. are overlapping, even if on above-mentioned width the most linearly Shape ground makes the pressurization part of single movable part, is also not easy to make between terminal and strap Contact pressure is the most identical at any one terminal.For the impact of this deviation, if guaranteeing significantly to work as Rotatable parts are made to support flat leading from below to obtain contact pressure when rotating towards closed position The variable bit amount of the supporting arm of body and bending deflection, and the addendum modification of reality to be incorporated in this variable In the amount of position, then can relax the impact of this deviation.In patent documentation 1, to this end, at supporting arm Gap is set between portion and the diapire of housing, and the size in this gap is set as at supporting arm Along with being gradually increased from trend rear end, linking part position under free state.But, by variable bit amount Being set to big way, result can cause the height dimension of adapter correspondingly to become big, and this runs counter to Want the requirement of miniaturization as far as possible.Further, even if increasing variable bit amount, terminal is the completeest The most freely conjugate, but the supporting arm of each terminal is by being pressed via a strap Press and bending deflection, therefore, the plus-pressure produced by movable part and propping up from all terminals The counter-force in bearing arm portion add up to balance state under, at each terminal each other, with strap it Between contact pressure and addendum modification remain deviation.

In the present embodiment, it is not over increasing the variable bit amount of above-mentioned supporting arm, and makes to live The actual addendum modification of supporting arm when dynamic component arrives closed position and relative to strap Contact pressure become uniform each other at terminal.

In the present embodiment, at the rear end lower edge of the first rear support arm 27 of the first terminal 20 It is provided with teat 27B.Thus, when rotatable parts from the open position shown in (A) of Fig. 5 to When reaching the closed position of (B) of Fig. 5, above-mentioned first rear support arm 27 bending deflection and above-mentioned Teat 27B abuts with the upper surface of the diapire 15 of housing 10, stops above-mentioned first rear support arm 27 conjugate further.Thus, about the first terminal 20, in all terminals after above-mentioned first The addendum modification of bearing portion 27 is identical.Further, in the case of this addendum modification, teat 27B is from above-mentioned The diapire 15 of housing 10 is by counter-force, and therefore in all terminals, contact pressure is the most identical.So, The variable bit amount of supporting arm will not be excessive, and can eliminate the inclined of addendum modification and contact pressure Difference.The rigidity of diapire 15 is high, therefore, it is possible to guarantee that counter-force i.e. contact pressure is bigger.Additionally, energy Enough prevent strap waving in the vertical direction, contact pressure change on wiring direction.

First cam part of ＜ movable part and the second cam part ＞

In the present embodiment, in order to utilize the first press section and the second press section relative to flat Conductor pressing the first terminal and the second terminal, movable part 3 has with by the first terminal and the The mode that first compression zone of two-terminal and the second compression zone lift respectively play a role first Cam part 55 and the second cam part 56.

First cam part 55 with the first compression zone 24A sliding contact of the first terminal 20 rotating Though scope in be formed as cam rottion angle the most all there is the rounded portions of constant cam radius Point, therefore, the cam displacement caused because of the rotating self of the first cam part 55 will not be produced. The rotational axis x of movable part 3 being merely by being caused by the second cam part 56 described later Mobile and that rotational axis x is common above-mentioned first cam part 55 that rises of position also rises movement, Thus produce same amount of displacement.Thus, in the present embodiment, as long as to the second cam part 56 Movement illustrate, it becomes possible to understand the first compression zone 24A and second of the first terminal 20 The displacement of the second compression zone 34A of terminal 30.

With reference to (B) of Fig. 2, the shape of the second cam part 56, epirelief wheel face 56A and under convex The magnitude relationship of the cam radius of wheel face 56B is described above.This second cam part 56 was rotating In journey, its rotational axis x also moves up and down, in order to easy to understand, shown in (A) of Fig. 6 The position of rotational axis x is motionless and the appearance of cam surface in the case of being positioned at fixing point, then exists Appearance after moving up and down overlapping rotational axis x further in (B) of Fig. 6 is said Bright.In (A) of Fig. 6, (B) of Fig. 6, movable part 3 is just opened from open position Begin the position of the second cam part 56 after rotating be set to position ＜ 1 ＞, will be rotated further and this Position when second time abutment of two cam part 56 is positioned at the neutral line Z of cam is set to position ＜ 2 ＞, position when will rotate into closed position are set to position ＜ 3 ＞, it is shown that the second of position Cam part 56.Further, by above-mentioned position ＜ 1 ＞, ＜ 2 ＞, the ＜ 3 second cam part 56 at ＞ Second on abutment P token and be set to P1, P2, P3, by second time abutment Q It is expressed as Q1, Q2, Q3.

In (A) of the Fig. 6 illustrated in the position of fixed bias circuit line X, movable part 3 from Open position start to rotate and via position ＜ 1 ＞, ＜ 2 ＞ turn to the position ＜ 3 of closed position ＞, on above-mentioned rotational axis x, the second of the second cam part 56 abutment P according to P1, P2, The order of P3 moves, and second time abutment Q moves according to the order of Q1, Q2, Q3.About Abutment P on second, when being positioned at P2 on abutment P be positioned at top portion in the height direction Position, about second time abutment Q, when being positioned at Q2, second time abutment Q is positioned at and leans on most The position of bottom.That is, as on second abutment P be P2 and time second time abutment Q is Q2 Like that, on second in short transverse the distance of abutment P and second time abutment Q at P2 and Q2 is maximum when being both positioned at neutral line Z.Thus, now, the of the second terminal 30 The bending deflection amount of the second pressurized arm 34 of two compression zone 34A is maximum.

Secondly, actually defer to shown in (B) of Fig. 6 shown in (A) of above-mentioned Fig. 6 The action of the second cam part 56, each position Q1 of second time abutment Q, Q2, Q3 be at height Do not move on degree direction and before second as the second terminal 30, fix the upper limb of arm 36 The state moved in the horizontal direction on the upper limb of horizontally extending cam support 36A.As Upper described, due to each position Q1 of second time abutment Q, Q2, Q3 the most not It is mobile, so the short transverse of these positions shown in (A) of Fig. 6 moves (B) at Fig. 6 In show as the movement of position of rotational axis x.That is, rotational axis x is in (B) of Fig. 6 Move in the height direction according to the order of X1, X2, X3.

From (B) of Fig. 6 it can be seen that move with the order according to position X1, X2, X3 Centered by rotational axis x rotate and the second of movement on abutment P, the biggest Amplitude moves while changing position according to the mode of P1, P2, P3.This is abutment P on second Short transverse amount of movement is that the short transverse of second time abutment Q in (A) of overlapping Fig. 6 is moved The height of abutment P on momentum (that is, the short transverse amount of movement of rotational axis x) and second Direction amount of movement sum is suitable with the elastic addendum modification of above-mentioned second compression zone 34A.Along with this The bigger short transverse amount of movement of abutment P, abutment P on second on above-mentioned the second of sample And second time abutment Q cross neutral line Z and move along transverse direction, therefore, upper simultaneously Before and after stating neutral line Z, operator feels big click sense.

Secondly, for present embodiment, it is pointed to the first rear support arm 27 of the first terminal 20 The variation of teat 27B of rear end illustrate.Even if teat 27B is unlike (A) of Fig. 2 It is shaped generally as quadrilateral shape like that, can be formed as that there is the conical surface as (A) of Fig. 7 Low triangle, can be positioned at the position comparing rear end slightly by front as (B) of Fig. 7, Can not be arranged at the first rear support arm 27 as (C) of Fig. 7 and be arranged at housing The diapire 15 of 10, in addition it is also possible at the first rear support arm 27 as (D) of Fig. 7 Opposite disposed with the both sides of the diapire 15 of housing 10.

Secondly, in the present embodiment, in the first terminal 20, constitute the first supporting arm 22 Forward portion first before fix arm 26 the first connecting portion 29 as mentioned above in front end and the There is between one linking part 23 protrusion 28 that ground is the most prominent in mountain shape.From Fig. 8 (A), (B) it can be seen that the neighboring area S(S1+S2 that is positioned at this protrusion 28), Owing to linking part 23 also is located at relation herein, in this neighboring area, in order to realize keeping terminal Purpose, the groove width of the terminal groove of housing becomes narrow (with reference to the Fig. 8 only illustrating housing (B)).Thus, when by the first connecting portion 29 and circuit substrate soldering of above-mentioned the first terminal 20 During connection, scaling powder have on the surface of the first connecting portion 29 rise and towards linking part 23 side shifting Tendency.When being not provided with above-mentioned protrusion 28, there is following situation: scaling powder is in terminal table Narrow gap between face and terminal groove arrives under the effect of capillarity linking part 23, According to the amount of the scaling powder moved, there is the further movement of situation of scaling powder.Therefore, at this In embodiment, by guaranteeing above-mentioned protrusion 28 significantly, even if the amount of the scaling powder of movement is slightly Many, scaling powder is also stranded in this in the diffusion into the surface of this protrusion 28, does not haves further The scaling powder of movement.So, scaling powder will not move and be attached to carry out between strap The terminal back-end location of electrical contact.

Secondly, the movable part 3 being formed with cam part is further described.This embodiment party Transitional region in formula, after the movable part 3 shown in (A) of Fig. 9 and between lower surface 58 have the curved outer wall being formed as the circular arc centered by rotational axis x.Thus, front and back Position restraining portions 18B of the island of the position of movable part 3,18C it is located nearest on direction Front surface and the interval of above-mentioned transitional region 58, no matter movable part 3 is positioned at open position and pass Which position between closed position, is all constant.

When movable part 3 is carried out rotating operation, there is movable part 3 by power towards the rear Situation, in the case of this power is big, result will cause above-mentioned transitional region 58 in rotation process Conjugate movement towards the rear.Assume when as (B) of Fig. 9 transitional region 58 for straight line distance The distance of pivot center and non-constant time, in rotation process, at above-mentioned distance the best part, Exist movable part move towards the rear with this therefore cause apart from suitable amount terminal by excessively by Press and the worry of breakage.In the present embodiment, owing to transitional region 58 is arc-shaped, therefore Distance between transitional region and position restraining portions 18B, 18C is constant in rotation process, even if Assume that movable part abuts with terminal, also will not excessive press terminal, it is possible to prevent terminal damaged.

Secondly, for the cam face of the second cam part 56 of movable part 3, companion is not only existed Along with in the rotation second of movable part 3, abutment P and the second abutment Q form the position of Fig. 6 Put relation and situation that the second cam part 56 rotates, it is possible to be designed with various position relationship. In the example shown in Fig. 6, in order to obtain maximum cam addendum modification, abutment P on second is made to reach The Q2 of the position in portion most on the lower is reached to the P2 of position in top portion and second time abutment P It is positioned on neutral line Z simultaneously, but in the present embodiment, abutment on second can not only be passed through The both sides of P and second time abutment Q obtain cam addendum modification, and can increase second time abutting Cam addendum modification at some Q, the most not necessarily makes the top portion of abutment P on second The position Q2 in the portion most on the lower of position P2 and second time abutment is positioned on neutral line Z simultaneously, And, it is not necessary to arrive neutral line Z.

Each example of (B)～(D) of Figure 10 is shown.In (A) of Figure 10, in order to compare Relatively the position relationship of already described Fig. 6 is shown.For this position relationship, as from (A) of Figure 10 As being seen, it is thus achieved that abutment P2 and second on the second of the moment of maximum cam addendum modification Lower abutment Q2 is positioned to constitute simultaneously and becomes straight relative to the cam support 36A of the second terminal 30 On the neutral line Z of the line at angle, but in (B)～(D) of Figure 10, both and non-concurrent position In neutral line Z, or a side does not arrive neutral line Z.

In (B) of Figure 10, when movable part 3 arrives closed position, second time abutment Neutral line Z is significantly crossed compared with the situation of (A) of Q3 with Figure 10, but abutment on second P3 is positioned on neutral line Z.Thus, obtain after click sense at epirelief wheel face 56A, under convex Wheel face 56B obtains click sense, but the click sense at this lower cam surface 56B is big.

Secondly, in (C) of Figure 10, when movable part 3 arrives closed position, second time Abutment Q3 arrives the position on neutral line Z, and now, on second, abutment P3 arrives the most logical Cross the position after neutral line Z.

Further, (D) of Figure 10 illustrates two kinds of situations, as a kind of situation, in order to compare, By the example of (B) of Figure 10 abutment P1, P2, P3 and second time abutment on second Q1, Q2, Q3 represent, for another kind of situation, with abutment P1 on second ', P2 ', P3 ' And second time abutment Q1 ', Q2 ', Q3 ' represent.
