Both sides in the substantial middle of the medial surface of aforementioned accommodation section 1a, form a pair of

spring accommodation section

1c, 1c, this a pair of

spring accommodation section

1c, 1c are by the elongated slot formation along the state (configuration of Ha font) that has the circular arc at roughly the same center with circular arc above the shell 1 and tilt slightly, the length direction of this spring accommodation section 1c relatively to medial surface, become the 1d of wall portion, the 1d of the location, two ends of the back-moving spring (elastic component) 2 that will describe later.In addition, between aforementioned a pair of

spring accommodation section

1c, 1c, the connection groove section 1e at the dark end that formation is narrower slightly than the width of aforementioned spring accommodation section 1c, so that connect both, in addition, relative with aforementioned spring accommodation section 1c to a pair of aforesaid wall 1d of portion, 1d between, form slip slot part 1f, the 1f link to each other with described connection groove section 1e, the jut 4d of the driving body 4a that describes later carried out slide-and-guide.

In this case, aforementioned link slot 1e forms with identical size continuously with

slip slot part

1f, 1f, and different is with aforementioned spring accommodation section 1c being formed linearity, forms with aforementioned peristome 1b top circular-arc to have the circular-arc of same central point.

In addition, on side, form the guiding groove section 1g that constitutes by top circular-arc circular-arc elongated slot with same central point with aforementioned peristome 1b near accommodation section 1a inner bottom surface.By make 4e of direction protrusion portion on the driving body 4a that is arranged on the control member of describing later 4 and the jut 4d slip of leading in this guiding groove section 1g and slip slot part 1f, control member 4 slides along circular arc and moves.But between forms predetermined gap.

In a pair of spring accommodation section 1c, the 1c of aforementioned shell 1, hold and keeping a pair of back-moving

spring

2,2 that constitutes by the metal wire rod that is wound into coiled type.In this case, two ends of back-moving spring 2 compression contact spring accommodation section 1c relatively to the 1d of wall portion, 1d, whereby, position by two ends to back-moving spring 2, back-moving spring 2 is remained in the 1c of spring accommodation section.In addition, a pair of back-moving

spring

2,2 is relatively on one of the ground configuration distolateral 1d of wall portion, 1d, dispose respectively by having the distance piece 3 that the isoelastic material of rubber constitutes, thereby one of a pair of back-moving

spring

2,2 distolaterally contacts with the 1d of wall portion via distance piece 3.The jut 4d that is arranged on the driving body 4a of the control member of describing later 4 is clamped between this

distance piece

3,3, transmits the spring force of a pair of back-moving

spring

2,2, and aforementioned operation member 4 is remained on the neutral position.

Control member 4 utilizes insulating material such as synthetic resin to form, and the support 4e that is roughly square driving body 4a, has operation projection (knob) 4c of the circular-arc flange part 4b that is provided with at this drivings body 4a upside and is supported an end of back-moving spring 2 by the plane forms.On the side of aforementioned driving body 4a, in its substantial middle position, setting is elongated circular-arc laterally projecting jut 4d to Fig. 1, and this jut 4d combines with the connection groove section 1e of shell 1.In addition, two ends of jut 4d form outwards outstanding curved surface shape, contact with distance piece 3 by these curved two ends, make distance piece 3 strains.In addition, the distance between two ends of jut 4d exists in its size under the situation of skew, than below the 1d of wall portion between distance, than above the 1d of wall portion between distance little.

Like this, on the 1d of wall portion of the side that the connection groove section 1e by spring accommodation section 1c connects, the distance piece 3 that the elastomeric material that configuration is contacted by the other end with back-moving spring 2 constitutes, owing to the driving body 4a of connection groove section 1e combination on the curved surface of two ends of the jut 4d that is provided be formed, contact with the other end of distance piece 3 and make distance piece 3 strains, so, when control member 4 resets to middle position, the impact sound when the jut 4d that can suppress driving body 4a contacts with the end of back-moving spring 2.

In addition, downside at jut 4d, two ends that stride across the plane are being set highlightedly and are being elongated circular-arc guiding projection 4e along the projected direction identical with jut 4d, this guiding projection 4e is attached on the guiding groove section 1g on the accommodation section 1a that is formed at shell 1 slidably.

With when connection groove section 1e that forms on the 1a of the accommodation section of shell 1 and slip slot part 1f combine, guiding projection 4e combines with guiding groove section 1g and carries out slide-and-guide, will operate projection 4c and be circular-arc ground slide by jut 4d.In this case, being provided with the plane that drives body 4a becomes the sliding surface that the inner bottom surface with accommodation section 1a slides, and guiding projection 4e and guiding groove section 1g might not be necessary, can form as required.

In addition, because a pair of back-moving

spring

2,2 is configured to the Ha font, so, near the neutral position, from the below slightly at the two ends of the elongated circular-arc jut 4d that forms control member 4, apply the elastic force of a pair of back-moving

spring

2,2, so, control member 4 is pushed to the top of Fig. 1, till moving to the top of jut 4d always and the upper inside surface of connection groove section 1e contacting.At this moment, because the distance between the 1d of wall portion is elongated along with advancing upward, be positioned at the top so be accompanied by this control member 4, back-moving

spring

2,2 is at the close 4d of wall portion in the end of control member 4 sides.Wherein, surpass under the situation of predetermined value in the difference of elastic force, the maximum of the skew of neutral position becomes the poor of the length of jut 4d and the length between the 1d of wall portion.Thereby, when back-moving

spring

2,2 in the end of control member 4 sides during near the 1d of wall portion, even under the situation of the difference of the elastic force that causes thus, also very little in the offset of the neutral position of control member 4 with left and right sides back-moving

spring

2,2.

In addition, under the state above control member 4 is positioned at, even jut 4d is longer than connection groove section 1e slightly, both also impartial basically strains of back-moving spring 2,2 (elastic component), two

distance pieces

3,3 become and jut 4d and the 1d of wall portion state of contact, even the elastic force of left and right sides back-moving

spring

2,2 has difference, the neutral position of control member 4 can not be offset yet.

In addition, if control member 4 can be moved upward fully, then control member 4 is moved upward, the state that is connected with end difference 1d up to becoming that strain does not take place two

distance pieces

3,3 and with jut 4d, even the elastic force of left and right sides back-moving

spring

2,2 has the deflection of difference, elastic component difference is arranged, the neutral position of control member 4 can not be offset yet.

Like this, by forming slip slot part 1f circular-arc, the jut 4d that drives body 4a is slided on slip slot part 1f, can carry out slide and maintenance with circular-arc to operation projection 4c, so,, and can dwindle the size of driving body 4a on glide direction in the slide scope that can increase operation projection 4c, so, can when guaranteeing to operate the operating characteristics of projection 4c, make it miniaturization.

In addition, drive body 4a relatively to another plane on plane on, be fixed with the slide 5 that constitutes by conductive metal material.The contact chip 5a of a plurality of single armed shapes is being set on this slide 5, and this contact chip 5a contacts with conductive pattern (not shown) on being arranged on the base of describing later 6 and breaks away from.

Base 6 is made of laminated plates such as phenolic resins, forms the conductive pattern (not shown) that is made of electric conducting materials such as steel foil and carbon from the teeth outwards, and forms the collector body and the resistive element of variable resistance.In addition, be fixed with the outside terminal 7 that the conductive metal plate that is connected with through hole etc. with aforementioned conductive pattern is made overleaf.

Aforementioned base 6, its rear side becomes overall fixed on the flat lid 8 that is made of insulating material such as synthetic resin, aforementioned conductive pattern be fixed on aforementioned driving body 4a on the contact chip 5a of aforementioned slide 5 contact the mode that breaks away from and be installed on the aforementioned shell 1 to ground relatively.In addition, under the situation that forms aforementioned slide 5 and aforementioned conductive pattern, also can on aforementioned driving body 4a, form aforementioned conductive pattern, on aforementioned base 6, form aforementioned slide 5.

When the slidingtype electric component of assembling said structure, aforementioned distance piece 3 is inserted aforementioned shell 1 a pair of aforementioned

spring accommodation section

1c, 1c relatively to the distolateral 1d of wall portion, a 1d in, with a distolateral state of contact under, aforementioned back-moving spring 2 be inserted into another of this distance piece 3 distolateral in.

Secondly, by the aforementioned jut 4d and the aforementioned guiding projection 4e that will on the sliding surface of the driving body 4a of aforementioned operation member 4, be provided with, be inserted in the aforementioned connection groove section 1e that on the 1a of the accommodation section of aforementioned shell 1, is provided with and the aforementioned guiding groove section 1g and make it to overlap, to become overall fixed to be provided with the aforementioned cover 8 of the aforementioned base 6 of aforementioned conductive pattern, overlayed on the aforementioned slide 5 on the side of being fixed in contrast, install by methods such as usefulness riveted joint or bondings, and finish assembling.

Like this, because on the aforementioned driving body 4a of aforementioned operation member 4, to form the sliding surface of aforementioned jut 4d, and in the side table of fixing aforementioned slide 5 relatively to mode form, so, after on the aforementioned spring accommodation section 1c that aforementioned distance piece 3 and aforementioned back-moving spring 2 is installed to aforementioned shell 1, to be provided with the overlapping installation of sliding surface of the aforementioned jut 4d of aforementioned operation member 4 down from above, the side the aforementioned cover 8 of the aforementioned base 6 that is provided with conductive pattern to becoming overall fixed from it, finish assembling, so assembling is simple, can improve operation.In addition, because conductive pattern forms the shape that the side is a tabular surface of aforementioned driving body 4a, form conductive pattern easily.

Secondly, the action of the slidingtype electric component of said structure is described with Fig. 1 and Fig. 3.

At first, in initial condition shown in Figure 1, control member 4 (operation projection 4c) is positioned at the neutral position, in this state, the jut 4d that drives body 4a is inserted in the connection groove section 1e, and two ends of jut 4d contact with a pair of

distance piece

3,3, utilize a pair of back-moving

spring

2,2 applied forces, via a pair of

distance piece

3,3,4c remains on the neutral position with operating knob.

At this moment, become the state that balancedly keeps a pair of back-moving

spring

2,2 both applied forces, in addition, because the distance between two ends of jut 4d, its size than below the 1d of wall portion between distance, so, the rocking of aforementioned operation projection 4c that can suppress to be in the neutral position.

In addition,, become two

distance pieces

3,3 and jut 4d and the 1d of shell wall portion state of contact owing to utilize back-moving

spring

2,2 to push control member 4 to top, so, be positioned at predetermined neutral position.

For example as shown in Figure 3, when from this state, to operate projection 4c when the left shown in the figure is pushed, operation projection 4c slides mobile to the left, jut 4d slide-and-guide, guiding projection 4e slide-and-guide in guiding groove section 1g in slip slot part 1f moves thereby driving body 4a is circular-arc slip to left thereupon.Be accompanied by this slip and move, compression reseting spring 2 is come via back-moving spring 2 applied forces that distance piece 3 opposings are configured in the left side in the left part of jut 4d.When this slip was moved, the contact chip 5a of slide 5 slided on the surface of base 6, contacts with conductive pattern, became the state that contact is connected.On the other hand, as shown in Figure 3, right side back-moving spring 2 is accommodated in the spring accommodation section 1c on right side, thereby an end of control member 4 sides of the back-moving spring 2 on right side (actual connect be the distance piece 3 on right side) leaves the right part of the jut 4d of control member 4.

At this moment, driving body 4a becomes jut 4d and is and slides mobilely circular-arcly along forming circular-arc slip slot part 1f, on the other hand, forms linearity with the corresponding spring of circular-arc slip slot part 1f accommodation section 1c, 1c.Like this, back-moving spring 2 is configured in each back-moving spring accommodation section 1c in straight mode, because back-moving spring 2 roughly forms along the circular-arc slip moving direction of jut 4d, so when jut 4d was circular-arc slip on slip slot part 1f, back-moving spring 2 bent to linearity.Like this, because when jut 4d is circular-arc slip on slip slot part 1f, back-moving spring 2 can bend to linearity, so can keep linear state to use back-moving spring 2, in addition, vertically be added on the end face of back-moving spring 2 owing to will load, so can not twist, and owing to unusual load can be added on the jut 4d, so the action that can carry out control member 4 is stablized and resetted reliably.In addition, carry out from the neutral position that this operation projection 4c moves when action that glide direction is pushed slightly downwards, become to the moving of the Width of resistive element but should move, constant from the resistive element end to the distance of contact chip 5a, so output is almost constant.

When removing the pushing of operation projection 4c from the state of Fig. 3, one side utilizes back-moving

spring

2,2 to apply power upward, and one side is utilized back-moving spring 2 applied forces in compressed left side will drive body 4a to reset to neutral position shown in Figure 1.At this moment, the right part of jut 4d contacts with the distance piece 3 that the back-moving spring 2 that is configured in the right side applies the right side of power, can suppress the impact sound that distance piece 3 is at this moment produced.

In addition, near the neutral position, apply a pair of back-moving

spring

2,2 applied forces from the below slightly at the two ends of the elongated circular-arc jut 4d that forms control member 4, control member 4 is upwards shifted onto the top (direction vertical with the slip moving direction) of Fig. 1, and moves above jut 4d with till the inner face of connection groove section 1e upside contacts.In addition, when jut 4d is pushed to the top, owing to the 1d of wall portion tilts to dispose, so, even jut 4d also can withdraw gradually than the 1d of wall portion is outstanding more, an end of control member 4 sides of back-moving spring 2 contacts (actual in distance piece 3) respectively with the 1d of wall portion of shell 1, thereby reliably control member is positioned at the neutral position.Whereby, control member 4 can not rock at the slip moving direction, thereby improves reseting precision.In addition, by to right-hand the pushing shown in the figure time, also carry out action same as described above at aforementioned operation projection 4c, so, its explanation omitted here.

In addition, in above-mentioned first embodiment, aforementioned operation projection 4c and aforementioned driving body 4a become circular-arc slip to move, but the present invention is not limited thereto, for example, the shape that also can be in line slide to move (among second embodiment that describes in the back this example being described in addition), self-evident, also can obtain identical effect in this case.

In addition, conductive pattern constitutes illustrated gliding rheostat with resistive element and collector body, but also can form conductive pattern with the switch figure of conducting state and off-state, makes slipping switch.In addition, also the configuration of slide 5 and conductive pattern can be reversed, also they can be arranged on relative with the operation projection 4c that drives body 4a to the side on.

In addition, form back-moving spring 2 with helical spring, when back-moving spring 2 is configured to the Ha font, the part of touching with shell joint also forms the Ha font, so back-moving spring 2 can not twist, can be along moving smoothly with the perpendicular direction of the moving direction of control member 4.

In addition, owing between back-moving spring 2 and control member 4, install distance piece 3 additional, under the situation of the end surface shape that can not influence back-moving spring 2, control member 4 can move to the direction vertical with the moving direction of control member 4 smoothly, forming under the situation of back-moving spring 2 better effects if with helical spring.

In addition, because control member 4 is contained in the shell 1 in the mode that moves on circular arc, so even lengthening back-moving spring 2 can not maximize yet, so, can be under the situation of miniaturization, corresponding long stroke.In addition, owing to back-moving spring 2 usefulness vertical planes contact with control member 4, so can be along sliding resetting.

In addition, according to above-mentioned first embodiment, on the driving body 4a of control member 4, form jut 4d, this jut 4d is outstanding along the direction vertical with glide direction, and with a pair of back-moving spring 2, the distolateral combination of another of 2, and in the 1a of the accommodation section of shell 1, below the sliding surface that drives body 4d, a pair of spring accommodation section 1c is set side by side along glide direction, 1c, at this a pair of spring accommodation section 1c, form the connection groove section 1e that connects both between the 1c, and form aforementioned slip slot part 1f, this slip slot part 1f is connected with this connection groove section 1e, and at spring accommodation section 1c, in the 1c jut 4d that drives body 4a is carried out slide-and-guide, so, can with position that the driving body 4a of aforementioned magnetic component 4 overlaps on be set up in parallel the aforementioned spring accommodation section 1c that forms arrangement reset spring 2, thereby, arranging the structure that disposes aforementioned back-moving spring 2 with the glide direction of edge driving body 4a compares, can dwindle the size of the glide direction that drives body 4a, so, the size that can dwindle whole electric component.

In addition, in aforementioned first embodiment, install distance piece 3 additional, but this is also nonessential, in this case, back-moving

spring

2,2 contacts with jut 4d in the end of operation projection 4c side, and becomes the approaching state with the 1d of wall portion, so, can improve reseting precision equally in the neutral position.

Secondly, with reference to Fig. 8～Figure 11 second embodiment of the present invention is described.Fig. 8～Figure 11 represents the slidingtype electric component as second embodiment, Fig. 8 is the sectional arrangement drawing of major part, Fig. 9 is the amplification key diagram of the major part of Fig. 8, and Figure 10 is the drawing in side sectional elevation of major part, and Figure 11 is the amplification key diagram of the major part of Figure 10.In addition, because this second embodiment prior art example with the Figure 12 that illustrates previously and Figure 13 except that the part that the following describes is identical, so, except that characteristic of the present invention, omit its detailed description.

In this second embodiment, keeping out of the way the connecting portion that groove 22b and stator are kept out of the way groove 22c as the spring of the slide mass 22 of control member, end difference is made along with moving and outstanding laterally tapered portion 30 upward.In the neutral position of slide mass 22, the top of this tapered portion 30 is side-prominent to each back-moving spring 23 from stator 21b.Thereby an end of slide mass 22 sides by a pair of back-moving spring 23 contacts respectively with from the outstanding tapered portion 30 of spring stator 21b, to the middle position application of force of slide mass 22 to shell 21.At this moment, because slide mass 22 just had the gap originally in the direction vertical with the slip moving direction, so, back-moving

spring

23,23 by both sides pushes away slide mass 22 on aforementioned vertical direction (the last direction among Fig. 8), two back-moving

springs

23,23 contact with each

spring stator

21b, 21b respectively in an end of slide mass 22 sides.Whereby, slide mass 22 is positioned in neutral position shown in Figure 8.

Like this, tapered

portion

30,30 is set in the both sides of slide mass 22, the part of the length of tapered

portion

30,30 is than the distance between spring stator 21b, the 21b of shell 21, and its short part is than short between spring stator 21b, the 21b of shell 21.

In addition, this tapered portion 30 also can form arc surface, and whereby, control member 22 can move to the direction vertical with the slip moving direction of control member 22 smoothly.

In this second embodiment, also play the effect identical with first embodiment.
