Above-mentioned movable part 3 be supported to can from the open position shown in Fig. 2 through centre position as shown in Figure 3 till the interval of the off-position shown in Fig. 4 rotate.In Fig. 2, the rotational axis x of movable part 3 is positioned at the Lower Half of this movable part 3, and this Lower Half is incorporated in the open spaces 17 forming in the front portion of housing 10.In Fig. 2, be positioned at this open spaces 17 outer and compare the upper wall 14 of housing 10 the outstanding first half is configured for this movable part 3 being carried out to the operating portion 51 of rotating operation for user towards top.

The Lower Half of the above-mentioned movable part 3 in Fig. 2, the position corresponding with the first terminal 20, the second terminal 30 and fixture 40 on the Width of movable part 3 (at terminal board column direction and be and the rectangular direction of paper in Fig. 2), front and back be formed through allow the first terminal 20, the second terminal 30 and fixture 40 separately first press the first slot part 52, the second slot part 53 and the 3rd slot part 54 that arm 21, second is pressed the slit-shaped that the front portion separately of arm 31, upper arm parts 41 enters.Thereby the groove width of above-mentioned the first slot part 52, the second slot part 53 and the 3rd slot part 54 (with groove inner surface in the rectangular direction of paper width each other) forms the size slightly larger than the thickness of slab separately of above-mentioned the first terminal 20, the second terminal 30 and fixture 40.At above-mentioned the first slot part 52, the second slot part 53 and the 3rd slot part 54, be respectively arranged with groove inner surface the first cam part 55, the second cam part 56 and the 3rd cam part 57 together connected to each other.

From Fig. 2 (A), can find out, the first cam part 55 that is arranged at first slot part 52 corresponding with the first terminal 20 on terminal board column direction is positioned at the bottom of above-mentioned the first slot part 52 of the movable part 3 of open position, and forms 3/4 perimembranous around center of rotation and be divided into the shape that circle, remaining bottom right 1/4 perimembranous are divided into foursquare bight.The center of rotation of this first cam part 55 is positioned on the extended line of rotational axis x of movable part 3.By the rotation of movable part 3, make the first pressurized arm 24 elasticity displacements of the first terminal 20, this center of rotation moves up and down thus, but by the restriction of the edge of the front and back of the first compression zone 24A of concavity, is not moved on left and right directions.The direction of the elasticity displacement of above-mentioned the first pressurized arm 24 is the rectangular directions of direction of extending with this first pressurized arm 24, therefore the top of the first cam part 55 and the first abutment of the first compression zone 24A butt move at above-mentioned above-below direction, the neutral line Z that links this first abutment and above-mentioned rotational axis x extends along the vertical direction, and meets at right angles with fore-and-aft direction.The sliding contact of rotating in the above-mentioned first compression zone 24A of the concavity part (being positioned at the upper section and the below part of comparing the position of the neutral line Z side of keeping left compared by the top side of horizontal line of rotational axis x) of above-mentioned the first cam part 55 forms circular portion, so its radius is cam radius.Therefore, for this first cam part 55, when movable part 3 turns to the off-position of Fig. 4 from the open position of Fig. 2, the first cam part 55 only forms above-mentioned 3/4 circumferential portion of circular portion and the edge sliding contact of the first compression zone 24A, the cam radius of this sliding contacting part office is constant, therefore, only in this first cam part 55, do not produce cam displacement.

Which interval turned position till no matter movable part 3 is positioned at from open position to off-position, above-mentioned the first cam part 55 can contact with the anterior upper limb of the first supporting arm 22 of the first terminal yet, but mutually leave and be positioned at, compares this first position of supporting arm 22 top sides.

As long as above-mentioned the first cam part 55 can be accompanied by the rotation of movable part 3, by the first compression zone 24A guiding of concavity, rotated just enough, as shown in the figure, the part directed with the first compression zone 24A sliding contact can form circular portion, also can form non-circular other shapes that not wait radius.Now, even if non-circular cam face, the rotational axis x of the first cam part 55 also only moves up and down on neutral line Z, by the first compression zone 24A both sides' of concavity edge limitation, can not moved along transverse direction.

On the other hand, from Fig. 2 (B), can find out, the part of comparing the top side of horizontal line by rotational axis x and comparing the neutral line Z side of keeping left that is arranged at the second cam part 56 of second slot part 53 corresponding with the second terminal 30 on terminal board column direction forms circular-arc epirelief wheel face 56A, with respect to this epirelief wheel face, 56A has roughly fan type portion on right side, and in this scallop, form lower cam surface 56B, center of rotation is positioned at the position of the rotational axis x consistent with the center of rotation of the first cam part 55.Epirelief wheel face 56A form compare the first cam part 55 being shown in broken lines circular-arc part towards the outstanding cam surface of radius foreign side.The scallop that forms above-mentioned lower cam surface 56B have in (B) of Fig. 2 from the right end position of above-mentioned epirelief wheel face 56A towards right-hand extension extension and from the lower end position of epirelief wheel face 56A, towards lower right, extend obliquely extension, by the front end of extension from above-mentioned is linked and forms down cam surface 56B with cam surface 56B-3 under circular-arc centre towards right-hand linearly the rear lower cam surface 56B-2 extending towards the front lower cam surface 56B-1 of the linearly extension in below with from the front end of lower extension.No matter be which position of rotational axis x and above-mentioned lower cam surface 56B is linked, this distance is all greater than the cam radius of above-mentioned epirelief wheel face 56A.And, for link above-mentioned rotational axis x and front lower cam surface 56B-1, rear lower cam surface 56B-2 and middle time cam surface 56B-3 each distance that is the size of cam radius, under centre, cam surface 56B-3 is maximum, secondly, according to front lower cam surface 56B-1 and descend afterwards the order of cam surface 56B-2 to diminish.

Movable part 3 be shown be arranged in (B) of Fig. 2 of the state of open position, the epirelief wheel face 56A of the second cam part 56 is positioned at and compares the second compression zone 34A side of keeping left of the second terminal 30 and the position of leaving a little from this second compression zone 34A, and the rear lower cam surface 56B-2 of lower cam surface 56B contacts with the cam support 38 that the upper limb of the second anterior front fixedly arm 36 of the second supporting arm 32 as the second terminal 30 forms.Thereby, as second time butt contact of the position of lower cam surface 56B and above-mentioned cam support 38 butts, along with movable part 3 rotates towards off-position from open position, move towards the place ahead from rear the region and this position that according to the order of above-mentioned rear lower cam surface 56B-2, middle lower cam surface 56B-3, front lower cam surface 56B-1, are positioned at them.

From Fig. 2 (C), can find out, the 3rd cam part 57 that is arranged at the 3rd slot part 54 of fixture 40 correspondences on terminal board column direction is made into the shape roughly the same with the second above-mentioned cam part 56 that is positioned at the second slot part 53, have the scallop of stretching out towards right side, center of rotation is positioned at the position of the rotational axis x consistent with the center of rotation of the first cam part 55 and the second cam part 56.Above-mentioned the 3rd cam part 57 is with the difference of the second cam part 56: in the lower cam surface of the 3rd cam part 57, in Fig. 2 (C) and Fig. 3 (C), be positioned at the position left from the lower arm part 42 of fixture 40, do not contact with this lower arm part 42 with the rear lower cam surface 56B-2 of the second cam part 56 and the suitable part of middle lower cam surface 56B-3.Thereby, this the 3rd cam part 57 does not contact with above-mentioned lower arm part 42 when movable part 3 is positioned at open position and rotation process position, when movable part 3 arrives off-position, from Fig. 4 (C), can find out, the front lower cam surface 56B-1 of the 3rd cam part 57 contacts with above-mentioned lower arm part 42.

The connector of the present embodiment of such structure is used and is brought into play function according to following main points.

First, connector 1 is disposed to the assigned position on circuit substrate (not shown), by the corresponding portion brazing separately of the first connecting portion 29 of the first terminal 20, the second connecting portion 39 of the second terminal 30, the soldering fixed part 49 of fixture 40 and circuit substrate and be fixed.

For the connector 1 that is installed on by this way circuit substrate, movable part 3 is arranged at as shown in Figure 2 to the open position erecting, the state of the receiving peristome 16 of housing 10 is formed towards the rear (left in figure) opening, forms the state that can insert strap F.

Secondly, at movable part 3, be positioned at as shown in Figure 2 under the state of open position, the coupling part of strap F is inserted in above-mentioned receiving peristome 16 towards the place ahead.Between the first press section 25A of the first flexible arm 25 of the first terminal 20 and the first support 27A of the first rear support arm 27, between the second press section 35A of the second flexible arm 35 of the second terminal 30 and the second support 37A-1 of the second flexible support arm 37A, all become the slightly wide interval of thickness of the above-mentioned coupling part of comparing strap F, therefore, easily insert the coupling part of this strap F.But, about above-mentioned fixing piece 40, between the fastener 45A of the upper arm parts 41 of this fixture 40 and the fastener 49A of lower arm part 42, become the narrow interval of thickness of the coupling part of comparing above-mentioned strap F, therefore, thereby strap F lifts fastener 45A by make above-mentioned fastener 45A elasticity displacement with its front end on one side and widens after above-mentioned interval advances to assigned position on one side, above-mentioned fastener 45A enters the engaged part F3 of the incision-like of strap F, thus, strap F is kept temporarily.

Even if insert in the above described manner the coupling part of strap F, because above-mentioned movable part 3 is positioned at open position, the teat 27B therefore forming at the first lower edge that supports the first latter half of rear support arm 27 of arm 22 that forms the first terminal 20 is still positioned at the position of leaving from the diapire 15 of housing 10 and forms clearance C.

Secondly, as seen from Fig. 3 and Fig. 4, make movable part 3 via the position in rotation process of Fig. 3, turn to the off-position of Fig. 4.In addition, in Fig. 3 and Fig. 4, originally should illustrate being inserted with under the state of strap, but at utmost can elasticity addendum modification for what easily understand the first terminal 20, the second terminal 30 and fixture 40, displacement state while there is not strap is shown, but in fact strap is inserted into and exists, therefore, under the state identical with Fig. 5 (B), elasticity addendum modification stops at the amount of the thickness that has reduced strap, produces and the above-mentioned suitable contact of difference that at utmost can elasticity addendum modification.By the rotation of above-mentioned movable part 3, the first cam part 55, the second cam part 56 and the 3rd cam part 57 of movable part 3 are rotated centered by center of rotation X.In the rotation process shown in Fig. 3, the first cam part 55 and the 3rd cam part 57 respectively in from the first terminal 20 first state that fixedly the anterior upper limb of arm 26 and lower arm part 42 leaves, but from Fig. 3 (B), can find out, the position of second time abutment of the lower cam surface 56B of the second cam part 56 and cam support 38 butts the second terminal 30 lower cam surface 56B-2 from Fig. 2 (B) is transitioned into cam surface 56B-3 under the centre of this lower cam surface 56B.Due to cam radius, cam surface 56B-3 under centre is maximum, therefore, lower cam surface 56B-3 in the middle of second time abutment is transitioned into from rear lower cam surface 56B-2, and, the epirelief wheel face 56A of the second cam 56 utilize its on second abutment make the second pressurized arm 34 elasticity displacements of the second terminal 30 and the second pressurized arm 34 lifted towards top.Although move towards the rear from the place ahead on the upper limb of above-mentioned cam support 38 position of second time abutment, due to this linearly ground of upper limb horizontal-extending, therefore in short transverse, do not change.Thereby because cam radius cam surface 56B-3 place under above-mentioned centre at second time abutment place is maximum, therefore, the position of the rotational axis x of cam is towards the amount of the increment of top translating cam radius.Because the center of rotation of the first cam part 55 and the 3rd cam part 57 is all positioned at the position on rotational axis x too, therefore the first cam part 55 and the 3rd cam part 57 also all rise while rotating its center of rotation, and by its upper surface, the front portion of the upper arm parts 41 of the first pressurized arm 24 that is formed with the first compression zone 24A of the first terminal 20 and fixture 40 are lifted.Like this, by movable part 3, towards off-position, rotate, the first cam part 55 forming as one as the part of movable part 3, the second cam part 56 and the 3rd cam part 57 are rotated, thus, the front portion of the first pressurized arm 24, the second pressurized arm 34 of the second terminal 30 and the upper arm parts 41 of fixture 40 of the first terminal 20 is lifted respectively, by lever principle, the square elasticity displacement down respectively of the rear portion of the first flexible arm 25 of the first terminal 20, the second flexible arm 35 of the second terminal 30 and the upper arm parts 41 of fixture 40, and maintain its position.Thereby, the first terminal 20 utilizes the first press section 25A of the first flexible arm 25, the second press section 35A that the second terminal 30 utilizes the second flexible arm 35 towards below, to press strap F respectively and make its deflection, and this strap F is formed in the first rear support arm 27 of the first terminal 20 the first support 27A from below idiomorphism is subject to counter-force and is supported with the second support 37A-1 that is formed at the second flexible support arm 37A of the second terminal 30.Although the first rear support arm 27 of above-mentioned the first terminal 20 is towards below elastic deflection displacement, but the rear end lower edge of this first rear support arm 27 be formed with towards below outstanding teat 27B, when movable part 3 turns to off-position, the upper surface butt of the diapire 15 of above-mentioned teat 27B and housing 10 and stop the first rear support arm 27 to produce further elastic deflection displacement, make maximum displacement constant, and, be subject to the counter-force from diapire 15, make reliable and make it powerful to the clamping force of strap F between above-mentioned the first support 27A and the first press section 25A.

And, the engaged part F3 of incision-like of strap F and the fastener 49A of the lower arm part 42 of fixture 40 that by the second press section 35A of the first press section 25A of the first terminal 20 and the second terminal 30, towards below, are pressed and decline mobile lock, and utilize in upper and lower opposed mode, to approach two the fastener 45A and the 49A that arrange and prevent that strap F from deviating from.

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

The teat > of < the first terminal

At the strap of the form of present embodiment with in electric connector, keep metallic plate thickness of slab tabular surface and make, thereby, by being terminal board column direction by this thickness of slab direction setting, can arrange a plurality of terminals with high density.And, owing to forming high density arrangement, terminal distance is to each other little, therefore, in order at least to make connecting portion become easy with respect to the brazing of circuit substrate, two kinds of terminals are alternately arranged and connecting portion is configured on fore-and-aft direction the different position outside housing, increase connecting portion terminal board column direction interval to each other.Like this, while being arranged in broad range on the Width of a plurality of different types of terminals at strap, in most cases inhomogeneous in the rigidity of this Width upper shell and the deflection of strap.Moreover, when the assembling position errors when in the terminal dimensional discrepancy that the scale error when manufacturing causes to each other, with respect to the assembling of housing etc. are overlapping, even if make the pressurization part of single movable part on above-mentioned Width accurately linearlyly, be also not easy to make terminal all identical at any terminal with the contact between strap.Impact for this deviation, if guarantee significantly to support from below in order to obtain contact the variable bit amount of the supporting arm of strap and bending deflection when rotatable parts are rotated towards off-position, and actual addendum modification is incorporated in this variable bit amount, can relax the impact of this deviation.In patent documentation 1, for this reason, between supporting arm and the diapire of housing, gap is set, and the size in this gap is set as under the free state of supporting arm along with increasing gradually from trend rear end, linking part position.But, the way that variable bit amount is set greatly, result can cause the height dimension of connector correspondingly to become greatly, and this has run counter to and has wanted the requirement of miniaturization as far as possible.And, even if increase variable bit amount, terminal is not completely independent and free to deflect each other yet, but the supporting arm of each terminal is by being pressed and bending deflection via a strap, therefore, under the state of the plus-pressure being produced by movable part and the total balance of counter-force from the supporting arm of all terminals, at each terminal each other, and the contact between strap and addendum modification remain deviation.

In the present embodiment, excessively increase the variable bit amount of above-mentioned supporting arm, and the actual addendum modification of the supporting arm while making movable part arrive off-position and become each other even at terminal with respect to the contact of strap.

In the present embodiment, the rear end lower edge at the first rear support arm 27 of the first terminal 20 is provided with teat 27B.Thereby, when rotatable parts arrive the off-position of (B) of Fig. 5 from open position shown in Fig. 5 (A), the upper surface butt of the diapire 15 of above-mentioned the first rear support arm 27 bending deflections and above-mentioned teat 27B and housing 10, stops the further displacement of above-mentioned the first rear support arm 27.Thereby about the first terminal 20, in all terminals, the addendum modification of above-mentioned the first rear support portion 27 is identical.And the in the situation that of this addendum modification, teat 27B is subject to counter-force from the diapire 15 of above-mentioned housing 10, therefore in all terminals, contact is also identical.Like this, the variable bit amount of supporting arm can be not excessive, and can eliminate the deviation of addendum modification and contact.The rigidity of diapire 15 is high, therefore can guarantee that counter-force is that contact is larger.In addition, can prevent strap waving on above-below direction, the variation of contact on wiring direction.

The 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 to press the first terminal and the second terminal with respect to strap, movable part 3 has the first cam part 55 and the second cam part 56 that the mode so that the first compression zone of the first terminal and the second terminal and the second compression zone are lifted respectively plays a role.

No matter the first cam part 55 forms the circular portion how cam rottion angle all has constant cam radius in the scope of the first compression zone 24A sliding contact with the first terminal 20 rotation, therefore, can not produce the cam displacement that the rotation self because of the first cam part 55 causes.Be only the rising of position of the rotational axis x of the movable part 3 by being caused by the second cam part 56 described later move and common above-mentioned the first cam part 55 of rotational axis x also rise mobile, the displacement that produces thus same amount.Thereby, in the present embodiment, as long as the movement of the second cam part 56 is described, just can understand the displacement of the first compression zone 24A of the first terminal 20 and the second compression zone 34A of the second terminal 30.

With reference to (B) of Fig. 2, the magnitude relationship of the cam radius of the shape of the second cam part 56, epirelief wheel face 56A and lower cam surface 56B as mentioned above.This second cam part 56 its rotational axis x in rotation process also moves up and down, for easy understanding, in the situation that the position of rotational axis x shown in Fig. 6 (A) is motionless, be positioned at the appearance of the cam surface of fixing point, then in (B) of Fig. 6, further overlapping appearance after moving up and down of rotational axis x described.At Fig. 6 (A), in Fig. 6 (B), movable part 3 is just made as to position < 1 >, will further rotates and the position of second time abutment of this second cam part 56 while being positioned at the neutral line Z of cam is made as position < 2 >, position when turning to off-position is made as position < 3 > in the position of the second cam part 56 from open position starts to rotate, the second cam part 56 of position is shown.And, by second cam part 56 at above-mentioned position < 1 >, < 2 >, < 3 > places second on abutment with P souvenir, be made as respectively P1, P2, P3, second time abutment Q is expressed as to Q1, Q2, Q3.

In the position of fixed bias circuit line X and in the Fig. 6 illustrating (A), movable part 3 starts to rotate and via position < 1 >, < 2 >, turns to position < 3 > of off-position from open position, around above-mentioned rotational axis x, the second cam part 56 second on abutment P according to the ordinal shift of P1, P2, P3, second time abutment Q is according to the ordinal shift of Q1, Q2, Q3.About abutment P on second, when being positioned at P2 on abutment P in short transverse, be positioned at the position of top portion, about second time abutment Q, when being positioned at Q2, second time abutment Q is positioned at the position of portion most on the lower.That is, as abutment P on second be P2 and second time abutment Q while being Q2, in second in short transverse the distance of abutment P and second time abutment Q P2 and Q2 be both positioned at neutral line Z time be maximum.Thereby now, the bending deflection amount of the second pressurized arm 34 of the second compression zone 34A of the second terminal 30 is maximum.

Secondly, at each position Q1 action, second time abutment Q, Q2, the Q3 that in fact defer to the second cam part 56 shown in (A) of above-mentioned Fig. 6 shown in (B) of Fig. 6, in short transverse, do not move and state that on the upper limb of the cam support 36A that extends at the along continuous straight runs of the upper limb of the second front fixedly arm 36 as the second terminal 30, along continuous straight runs moves.As mentioned above, because each position Q1, Q2, the Q3 of second time abutment Q do not move in short transverse, so the short transverse of these positions shown in Fig. 6 (A) moves the movement that shows as the position of rotational axis x in (B) of Fig. 6.That is, rotational axis x moves in short transverse according to the order of X1, X2, X3 in (B) of Fig. 6.

From Fig. 6 (B), can find out, rotate centered by according to the rotational axis x of the ordinal shift of position X1, X2, X3 and abutment P on mobile second, on short transverse significantly mobile on one side according to the mode of P1, P2, P3 change position on one side.The short transverse amount of movement of second time abutment Q in this (A) that short transverse amount of movement of abutment P is overlapping Fig. 6 on second (, the short transverse amount of movement of rotational axis x) with second on the short transverse amount of movement sum of abutment P, suitable with the elasticity addendum modification of above-mentioned the second compression zone 34A.Be accompanied by the larger short transverse amount of movement of abutment P on so above-mentioned second, on second, abutment P and second time abutment Q cross neutral line Z simultaneously and move along transverse direction, therefore,, in the front and back of above-mentioned neutral line Z, operator feels the sense of rattling away of large click.

Secondly, for present embodiment, to being positioned at the variation of teat 27B of rear end of the first rear support arm 27 of the first terminal 20, describe.Even if teat 27B forms roughly quadrangle shape unlike Fig. 2 (A), can as Fig. 7 (A), form the low triangle with the conical surface, can being positioned at as Fig. 7 (B) compare position slightly on the front, rear end, can as Fig. 7 (C), not be arranged at the first rear support arm 27 and be arranged at the diapire 15 of housing 10, in addition, also can be as Fig. 7 (D) in both sides' opposite disposed of the diapire 15 of the first rear support arm 27 and housing 10.

Secondly, in the present embodiment, in the first terminal 20, the first front fixedly arm 26 that forms the place ahead part of the first supporting arm 22 between the first connecting portion 29 of front end and the first linking part 23, have be as mentioned above mountain shape significantly towards above outstanding protrusion 28.From (A), (B) of Fig. 8, can find out, the neighboring area S(S1+S2 being positioned at this protrusion 28), because linking part 23 is also positioned at relation herein, in this neighboring area, in order to realize the object that keeps terminal, the groove width of the terminal groove of housing becomes narrow (with reference to Fig. 8 of housing (B) is only shown).Thereby when by the first connecting portion 29 of above-mentioned the first terminal 20 during with circuit substrate brazing, scaling powder has and rises on the surface of the first connecting portion 29 and towards the tendency of linking part 23 side shiftings.When above-mentioned protrusion 28 not being set, there is following situation: scaling powder arrives linking part 23 in the narrow gap between terminal surfaces and terminal groove under the effect of capillarity, according to the amount of moved scaling powder, the situation that exists scaling powder to be moved further.Therefore, in the present embodiment, by guaranteeing significantly above-mentioned protrusion 28, even if the amount of mobile scaling powder is slightly many, scaling powder is also stranded in this in the diffusion into the surface of this protrusion 28, there will not be the scaling powder being moved further.Like this, scaling powder can not move and be attached to carry out and strap between the terminal back-end location electrically contacting.

Secondly, to being formed with the movable part 3 of cam part, be further described.In the present embodiment, the transitional region 58 below and between lower surface of the movable part 3 shown in Fig. 9 (A) has the curved outer wall that forms the circular arc centered by rotational axis x.Thereby, on fore-and-aft direction, be positioned at the front surface of the 18B of position limitation portion, 18C and the interval of above-mentioned transitional region 58 of the island of the position that approaches movable part 3 most, no matter which position of movable part 3 between open position and off-position is all constant.

When movable part 3 is carried out to rotating operation, exist movable part 3 to be subject to the situation of power towards the rear, in the situation that this power is large, result will cause above-mentioned transitional region 58 displacement towards the rear in rotation process to be moved.Suppose when transitional region 58 as Fig. 9 (B) is for straight line is apart from the distance of pivot center and when non-constant, in rotation process, therefore above-mentioned, apart from the best part, exist movable part to move the amount suitable with this distance towards the rear and cause terminal excessively to be pressed and damaged worry.In the present embodiment, because transitional region 58 is circular-arc, so the distance between transitional region and the 18B of position limitation portion, 18C is constant in rotation process, even if hypothesis movable part and terminal butt, also excessive press terminal not, can prevent that terminal is damaged.

Secondly, cam face for the second cam part 56 of movable part 3, not only exist abutment P and the second abutment Q in the rotation second be accompanied by movable part 3 to form the position relationship of Fig. 6 and situation that the second cam part 56 is rotated, can be designed to there are various position relationships.In the example shown in Fig. 6, in order to obtain maximum cam addendum modification, making abutment P on second reach the P2 of the position of top portion and second time abutment P reaches the Q2 of the position of portion most on the lower and is positioned on neutral line Z simultaneously, but in the present embodiment, not only can obtain cam addendum modification by the both sides of abutment P on second and second time abutment Q, and can increase the cam addendum modification at second time abutment Q place, therefore and the nonessential position P2 of top portion of abutment P on second and the position Q2 of the portion most on the lower of second time abutment of making be positioned on neutral line Z simultaneously, and, and nonessential arrival neutral line Z.

Illustrate Figure 10 (B)～each example (D).In Figure 10 (A), the position relationship of already described Fig. 6 is shown in order to compare.For this position relationship, as seen in (A) from Figure 10, obtain maximum cam addendum modification the moment second on abutment P2 and second time abutment Q2 be positioned on the neutral line Z forming with respect to the rectangular line of cam support 36A of the second terminal 30 simultaneously, but in Figure 10 (B)～(D), both are not positioned at neutral line Z, or a side does not arrive neutral line Z simultaneously.

In (B) of Figure 10, when movable part 3 arrives off-position, second time abutment Q3 compares and significantly crosses neutral line Z with the situation of Figure 10 (A), but on second, abutment P3 is positioned on neutral line Z.Thereby, at epirelief wheel face 56A, obtain click and rattle away after sense, at lower cam surface 56B, obtain the click sense of rattling away, but rattle away and feel greatly at the click at this lower cam surface 56B place.

Secondly, in (C) of Figure 10, when movable part 3 arrives off-position, second time abutment Q3 arrives the position on neutral line Z, and now, abutment P3 arrives by the position after neutral line Z on second.

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