Summary of the invention
The object of the present invention is to provide a kind of cylinder type toothbrush, wherein, can under the situation that does not reduce intraoral outwash effect, improve massage effect gum portion.
To achieve these goals, cylinder type toothbrush of the present invention comprises shaft-like handle, and this handle can hold by one hand, moves back and forth along central axis direction; The brush of drum, it is concentric shape and is installed on the leading section of shaft-like handle; In addition, above-mentioned brush adopt the spherical brush element of hard and soft spherical brush element along Handle axis to and the mixed structure that mixes, the spherical brush element of this hard is formed by the material of the hair of toothbrush, has the through hole that the handle leading section runs through at central part, and annual disk portion on every side from through hole, there are a plurality of materials to stretch out radially, this soft spherical brush element is formed by the soft resin of material softness than the hair of toothbrush, has the through hole that the handle leading section runs through at central part, and the annual disk portion on every side from through hole is extruded with a plurality of planar projections towards periphery.
In cylinder type toothbrush of the present invention, the mixed structure of the combination of two kinds of ball type devices that the brush of formation drum mixes vertically.The 1st spherical brush element is the spherical brush element of hard, its material by the hair of toothbrush forms, has the through hole that the handle leading section runs through at central part, and annual disk portion on every side from through hole, the multi-filament material stretches out radially, the 1st spherical brush element uses basically in the past, is used from the outwash of tartar removal and the effect of massage.The 2nd spherical brush element is soft ball type device, it is formed by the gentle soft resin of material softer than the hair of toothbrush, has the through hole that the handle leading section runs through at central part, and annual disk portion on every side from through hole, a plurality of towards periphery planar projections are outstanding, and the 2nd spherical brush element mainly plays the massage effect to gum.
Establish soft spherical brush element by being situated between between the spherical brush element of hard, the axial gross density of planting of the radial blade part in the spherical brush element of hard reduces, and improves usability, security.Owing between the radial blade part of the spherical brush element of hard, be situated between and establish outstanding towards periphery planar set of protrusions, so, can bring into play outwash ability steady in a long-term by suppressing axial the skewing of ring-shaped blade portion from the annual disk portion of soft spherical brush element.By the planar set of protrusions of soft spherical brush element, performance is to the excellent massage effect of gum portion.The planar set of protrusions of soft spherical brush element all by the radial blade part supporting of hard brush element, stops axial skewing, and thus, massage effect further increases.Spherical brush element of hard and soft spherical brush element cooperatively interact and performance are improved.
The spherical brush element of hard basically with patent documentation 1,2 in the element of record identical, usually by the nylon yarn manufacturing.By soft spherical brush element, adjust the axial gross density of planting, thus, pad or one lug boss are unwanted.From the aspect of usability, outwash performance, silk footpath is adapted in the scope of 0.09 thin～0.13mm of the silk used than common flat toothbrush.Be along Handle axis to, the occasion of the rectilinear form that external diameter is certain at brush, from the aspect of intraoral operability etc., the element external diameter is adapted in the scope of 12～16mm, more particularly, best, when being used for the adult, for about 15mm, when being used for child, for about 13mm.The thickness of the annual disk portion of the spherical brush element of hard is about 0.5mm, if increase the thickness of annual disk portion, then the spherical brush element of hard can be overlapped.
Soft spherical brush element can be made by soft resin is carried out integrally formed mode.As the kind of resin,, be suitably for SEBS resin that is used for toothpick etc. etc. from the viewpoint of hardness etc., even comprise according to food hygiene law and using if having, be still safely, and the rubber of hardness that can bring into play the brush performance is the soft resin of resin, and then whatsoever kind all can be used.When moulding,, can make brush have anti-microbial property by sneaking into antibacterial material.
As the shape of soft spherical brush element, be preferably full week, a plurality of tongue-shaped outstanding radially towards periphery petal-shaped of planar projection from annual disk portion.From the aspect of massage effect, the number of planar projection is preferably in 2～20 the scope.The external diameter of soft spherical brush element is preferably 0.6～1 times of diameter of the spherical brush element of hard, particularly is preferably in 0.7～0.95 times the scope.If the external diameter of soft spherical brush element is greater than the external diameter of the spherical brush element of hard, then the high-quality green tea of the spherical brush element of hard is difficult to contact with the oral cavity is inner, as the outwash performance reduction of the original function of toothbrush.If the external diameter of the spherical brush element of the relative hard of the external diameter of soft spherical brush element is minimum, otherwise then, the planar projection of soft spherical brush element is difficult to contact with the oral cavity is inner, and the massage performance reduces.Because in outwash, the high-quality green tea contact tooth of the spherical brush element of hard, gums etc. and being out of shape so massage the aspect of performance from performance to greatest extent, are preferably the external diameter degree slightly littler than the external diameter of hard brush element of soft brush element.
Guarantee, plant the viewpoint of gross density adjustment etc. from the intensity of self, the thickness of the annual disk portion in the soft spherical brush element is adapted in the scope of 1～2mm.From the intensity of self guarantee, the aspect of outwash etc., the thickness of planar overshooting shape is adapted in the scope of 0.5～1mm.
As the Handle axis of spherical brush element of hard and soft spherical brush element to spread pattern, best from function aspects, the ratio according to the spherical brush element of hard of a relative specified quantity of soft spherical brush element is provided with regularly.Specifically, the ratio of a spherical brush element of relative 1～3 hard of soft spherical brush element is desirable.In addition, equally aspect outward appearance,, be preferably in the both ends of element rows, the spherical brush element of hard is set from the aspect of the axial expansion of the radial blade part that suppresses the spherical brush element of hard.
At the shaft-like handle of supporting brush, because brush do not have circumferential directionality, thus can adopt the such type that does not have circumferential directionality of round bar, still, and if brush and handle are round bar shape, in the time of then on being positioned over the tabular surface of table top etc., rolling easily.Thus, be preferably the type of the such prism-shaped of triangular prism, still,, then eliminate such restriction if special-shaped flange described later is set.
The front of passing through hand-held part of holding that is preferably in handle is provided with flange part, wherein, particularly preferably preferably adopt a plurality of protuberances outstanding towards periphery comprise polygonal non-circular special-shaped flange.If have flange part, then cut off the saliva flowed from brush etc., be difficult to be attached on hand, be health, and, moreover, in the time of on the tabular surface that the cylinder type toothbrush is positioned over table top etc., brush does not contact with this tabular surface, also is health from this respect.In addition, if as its flange part, above-mentioned non-circular special-shaped flange is set, then same is the occasion of the so easy rolling shape of round bar at handle, even on the tabular surface that is positioned over table top etc., still do not roll, when having good stability, the apparent free degree of handle shape increases.
The material of handle is identical with other common toothbrush, is PP (polypropylene) or PET (PETG) etc.
Having the handle shape of flange part and the structure-irrelevant of brush, is effective.That is, for the brush that between the spherical brush element of hard, does not have soft spherical brush element, the brush of the distance piece beyond Jie between the spherical brush element of hard establishes soft spherical brush element etc., the handle shape that has this flange part all is effective.
The shape of brush be substantially along above-mentioned Handle axis to, the rectilinear form that external diameter is certain, still, also can be along Handle axis to, the non-linear shapes that external diameter changes.More particularly, because the external diameter of the spherical brush element of hard is more than or equal to the external diameter of soft spherical brush element, so the shape of brush is determined according to the external diameter of the spherical brush element of hard.That is, according to the external diameter of brush from Handle axis to leading section end and the mode that changes backward, the spherical brush element of the hard that external diameter is classified to change thus, constitutes the brush of non-linear shapes along the handle axially-aligned.
As non-linear shapes, can enumerate from Handle axis to both ends towards pars intermedia, the barrel shape that external diameter increases gradually; In contrast, from the axial both ends of handle towards pars intermedia, the drum type that external diameter increases gradually; From Handle axis to leading section towards rearward end, the truncated cone shape that external diameter increases gradually etc.Wherein, particularly be preferably the brush of barrel shape, compare, be preferably the former with the brush of rectilinear form.
In the occasion of the brush of barrel shape,,, easily internal tooth is carried out the outwash processing so enter intraoral inboard easily because the leading section of brush attenuates.Be to the side-prominent shape of periphery and bending to, outer peripheral face along Handle axis, extend, thus, easily outwash is carried out in the inboard of nipper along the curve of nipper.In the large-diameter portion of brush, basically, the diameter difference of the external diameter of the spherical brush element of hard and the external diameter of soft spherical brush element increases.Consequently, in large-diameter portion, the radial blade part of the spherical brush element of hard is more outstanding towards periphery from the periphery of soft spherical brush element.In the large-diameter portion that the radial blade part of the spherical brush element of hard is given prominence to more longways, high-quality green tea enters in the gap of tooth and tooth easily.In addition, high-quality green tea is crooked easily, and the occasion of removal tongue fur or the tactility of gum are improved.
On the other hand, in the more outstanding large-diameter portion of the radial blade part of the spherical brush element of hard, high-quality green tea is crooked easily, and tactility improves, and in contrast, the outwash effect reduces.For along brush axially make the outwash effect even, the silk material diameter that is arranged at the spherical brush element of hard of a large-diameter portion is effective greater than the silk material diameter this point of the spherical brush element of the hard that is arranged at a minor diameter.That is, the diameter of brush changes the diameter of the silk material that constitutes the spherical brush element of hard corresponding to the external diameter of the spherical brush element of the hard of determining it.
Because being the external diameter variation of the spherical brush element of hard specially, these effects when brush is non-linear shapes cause, so with the shape of the soft spherical brush element of brush or have or not, obtain in irrelevant mode, in other words, and Jie is located at the shape of the distance piece class between the spherical brush element of hard or has or not, and obtains in irrelevant mode.So, for the brush that between the spherical brush element of hard, does not have soft spherical brush element, or at the brush that has other distance piece class between the spherical brush element of hard, any distance piece class does not all have between the spherical brush element of hard brush, the non-linear shapes of this brush is effective.
Because in cylinder type toothbrush of the present invention, be installed on brush cylindraceous on the handle leading section and be spherical brush element of hard and soft spherical brush element along Handle axis to the mixed structure that mixes, so form Handle axis to the gross density of planting be fit to, not only usability, outwash function admirable, and the massage function admirable, level that can be higher satisfies whole performances, for performance is very high, the toothbrush that quality is high.In addition, with only and the brush of showing hard ball shape brush element compare, dry easily, also be health.

The specific embodiment
Below form of implementation of the present invention is described.
The cylinder type toothbrush of the 1st form of implementation such as Fig. 1～shown in Figure 3, by holding by one hand, the handle 10 of the round bar shape of back and forth operating along central axis direction, the brush cylindraceous 20 that is installed on the leading section of handle 10 constitutes.Handle 10 is by constituting by the hand-held main part 10A that holds, the maintaining part 10B that is installed on its front in mode removably.
The main part 10A of handle 10 basically, for having the cylindrical shape of the diameter that holds easily, still, hold easiness in order further to improve, part except leading section is along circumferentially, at interval 4 faces is carried out the section octagonal of the abnormity of chamfer machining according to 90 degree.In order to realize and being connected of a maintaining part 10B that from the front end face of main part 10A, screw rod 11 forward end are side-prominent.
A maintaining part 10B of handle 10 has the minor diameter axial region 12 of the isometrical round bar shape that keeps brush 20 at leading section.In order to keep brush 20, the front of minor diameter axial region 12 is a large diameter ca(u)lk portion 13, and rear end side is large diameter retainer 14.The cone shape of rearward end for enlarging gradually towards the rear diameter of maintaining part 10B, the maximum gauge portion in the rear end is provided with the flange part 15 of bigger shape.In addition, on the rear end face of maintaining part 10B, offer the screwed hole 16 of the screw rod 11 that is screwed with on the front end face that is arranged at main part 10A, be screwed into, main part 10A is connected with a maintaining part 10B, finish the assembling of handle 10 by this.
Assembled the handle of finishing 10 and had flange part 15 in hand-held front (the forward slightly front of length direction pars intermedia) of holding part.This flange part 15 is circumferentially spent the petal of 6 petals arranged side by side at interval according to 60 for being circular-arc to 6 side-prominent protuberances edges of periphery here, and its external diameter is about 19mm.In addition, the maximum outside diameter of the part except flange part 15 in the handle 10 is about 14mm here.
Here the material of handle 10 is PP (polypropylene) or PET (PETG) with main part 10A, a maintaining part 10B.
The material of the spherical brush element 20A of hard is the nylon that is generally used for the hair of toothbrush, more particularly, make by following mode, this mode is: such as making diameter is that about 800 of the nylon yarn of 0.09mm is bundled into the tow that bundle obtains and opens equably towards periphery, welding central part in the form of a ring, rounded shape carries out punching press to the inboard of weld portion, and its tow is separated.The external diameter of the spherical brush element 20A of hard (is being used for child's time spent in the scope of 12～16mm, in the scope of 12～14mm, when being used for the adult, in the scope of 14～16mm), the external diameter of annual disk portion 22 is about 7mm, thickness is about 0.5mm, and the radical of the silk material in the blade part 23 is about 800.In the occasion that the child uses, the external diameter of the spherical brush element 20A of hard is suitably for about 10mm.
On the other hand, soft spherical brush element 20B is formed by the material than the spherical brush element 20A of hard softness,, is the integrally formed product of the SEBS resin that is used for toothpick etc. here.The shape of soft spherical brush element 20B is at central part, through hole 24 with circle that the minor diameter axial region 12 of handle 10 connects, and around it, has annual disk portion 25, in addition at its outer circumferential side, has outside week, radially Tu Chu a plurality of tongue-shaped planar projection 26 from annual disk portion 25.A plurality of planar projections 26 here, according to equidistantly arranging, as a whole, soft spherical brush element 20B is the petal of 12 petals along circumferentially for 12 planar projections.
The external diameter of soft spherical brush element 20B is more smaller than the external diameter of the spherical brush element 20A of hard, (uses occasion with big human child, all in the scope of 12～13mm) in the scope of 12～13mm.Proportionally, the external diameter of soft spherical brush element 20B is preferably 0.6～1 times of external diameter of the spherical brush element 20A of hard, particularly is preferably 0.7～0.95 times.The diameter of the annual disk portion 22 of the spherical brush element 20A of the diameter of annual disk portion 25 and hard is identical, and thickness is than the thick approximately 1.4mm of annual disk portion 22.For the elasticity that obtains to be fit to, the thickness of projection 26 is the 0.7mm than the thin thickness of annual disk portion 25.
In addition, in the cylinder type toothbrush of the 1st form of implementation, the spherical brush element 20A of hard and a soft spherical brush element 20B of replacing vertically two coincidences overlap, at two ends, soft spherical brush element 20B is set, thus, constitute brush 20, more particularly, between the ca(u)lk portion 13 and retainer 14 of the fusion of the minor diameter axial region 12 on the leading section that is formed at handle 10, be packed with outward and state spherical brush element 20A of hard and above-mentioned soft spherical brush element 20B, by fixing at the state of pressurization vertically, constitute brush 20, this brush 20 is installed on the leading section of handle 10.
The number of the spherical brush element 20A of the hard here is 2 * 9～10, and the number of soft brush element 20B is 10～11, and the total length of brush is in the scope of 18～20mm.
To the using method and the performance of the cylinder type toothbrush of the 1st form of implementation of formation describe like this.
Hold the handle 10 of cylinder type toothbrush, brush 20 is inserted in the oral cavity, make handle 10 motions vertically, thus, brush teeth.In addition, gum is massaged.In addition, outwash is carried out on the surface of tongue, remove tongue fur.Brush 20 is a mixed structure, wherein, two spherical brush element 20A of hard and a soft spherical brush element 20B alternately arrange, only the spherical brush element 20A of hard props up and plants gross density, thus, although do not adopt pad, one lug boss, the axial gross density of planting descends, usability improves, and makes the danger of gum damage also few.
Relative this situation, in outwash, the high-quality green tea of the radial blade part 23 of the spherical brush element 20A of hard skews, thus, even under the situation of external diameter of soft spherical brush element 20B less than the external diameter of the spherical brush element 20A of hard, by being assembled in the planar projection 26 of the soft spherical brush element 20B in the brush 20, effectively gum is massaged.Thus, the massage performance improves.
In addition, because between the radial blade part 23 of the spherical brush element 20A of hard, being situated between is provided with the planar projection 26 of soft spherical brush element 20B, suppresses the distortion that skews of radial blade part 23, brush 20 is durable.Because the planar projection 26 of soft spherical brush element 20B also is supported on the radial blade part 23 of the spherical brush element 20A of hard of adjacency, so prevention skews, brings into play high massage effect steadily in the long term.
Owing on handle 10, have flange part 15, so in brushing teeth, can not allow the hands of making dirty such as saliva, health not only, and is as shown in Figure 9 placed the cylinder type toothbrush on table top etc., at this moment, by flange part 15, handle 10 tilts, thus, brush 20 is from placed side come-up, do not contact with table top etc., thus, from in this respect, flange part 15 is useful for the health aspect.
In addition, because the flange part 15 of handle 10 is petal non-circular, thus although handle 10 is round bar shape as a whole, the danger of on the placed side, not rolling, not first-class from platform, the danger of dropping because of carelessness.From in this respect, flange part 15 helps health.Handle 10 has flange part 15 and the effect that produces is effective for the cylinder type toothbrush that all have the brush beyond the brush 20 of mixed structure.
In addition, owing to can take off from main part 10A,, be economical so, can realize the replacing effect of brush 20 by brushing the replacement of maintaining part 10B as the brush maintaining part 10B of the leading section of handle 10, can bring into play function.
In addition, soft spherical brush element 20B is set at the two ends of brush 20.Thus, radial blade part 23 forward end that suppress the spherical brush element 20A of hard of front slant down and situation about opening.In addition, the radial blade part 23 that suppresses the spherical brush element 20A of hard of rear end side slants down and situation about opening to the back-end.In addition, equally from the outward appearance aspect, constitute the brush 20 of characteristics.
The cylinder type toothbrush of the 2nd form of implementation is brush 20 with the difference of the cylinder type toothbrush of the 1st form of implementation shown in Figure 10～15.The cylinder type toothbrush with the 1st form of implementation is identical in fact for structure beyond the brush 20.
The non-linear shapes that brush 20 in the cylinder type toothbrush of the 2nd form of implementation changes vertically for its external diameter, more particularly, for from axial both ends towards pars intermedia, external diameter increases gradually, outer peripheral face is laterally the so-called barrel shape of shape bending of projection vertically.
, it should be noted that the external diameter of soft spherical brush element 20B is certain here, here is 13mm.To this, only the external diameter of the spherical brush element 20A of hard increases gradually from axial both ends towards pars intermedia, according to being 14mm at leading section, is 19mm at pars intermedia, is that the mode of 17mm changes in rearward end.More particularly, the annual disk portion 22 of the spherical brush element 20A of hard is 7mm with the external diameter of the annual disk portion 25 of soft spherical brush element 20B, the external diameter of soft spherical brush element 20B also is certain, be 13mm, only the length of the radial blade 23 among the spherical brush element 20A of hard changes, thus, the spherical brush element 20A of hard, and then the external diameter of brush 20 changes.
The external diameter of the spherical brush element 20 of hard is poor, according to the ratio of the external diameter of the spherical brush element 20A of hard of the relative minimum diameter of external diameter of the spherical brush element 20A of hard of maximum gauge, is adapted in 1.2～1.5 the scope.If this ratio is little, then indeterminate with the difference of the performance of the brush 20 of linearity, in excessive occasion, the shape of brush 20 breaks away from cylindric, near discoid, reduces as brush 20 original performances.
In addition, in this brush 20, also be 0.12mm (or 0.09mm) according to the silk footpath that is arranged at both ends than the spherical brush element 20A of the hard of minor diameter, the silk footpath that is arranged at the spherical brush element 20A of larger-diameter hard of pars intermedia is the mode of 0.14mm (or 0.12mm), and the silk footpath of the spherical brush element 20A of the hard of a large-diameter portion is greater than the silk footpath of the spherical brush element 20A of hard of a minor diameter.
According to the cylinder type toothbrush of the 2nd form of implementation, not only have effect (effect of the mixed structure that spherical brush element 20A of hard and soft spherical brush element 20B mix etc.), and obtain following new effect by the cylinder type toothbrush acquisition of the 1st form of implementation.
Because toothbrush 20 is a barrel shape, leading section attenuates, so enter intraoral inboard easily, easily internal tooth is carried out outwash and handles.Because outer peripheral face carries out outwash to the inboard of nipper easily along the curve of nipper.In the large-diameter portion of axial pars intermedia, the radial blade part 23 of the spherical brush element 20A of hard is more outstanding partly.Thus, long at the large-diameter portion high-quality green tea of the axial pars intermedia that is formed at head, high-quality green tea enters in the gap of tooth and tooth easily.In addition, long high-quality green tea is crooked easily, in the occasion of removing tongue fur, with the sense of touch raising of gum.
On the other hand, in the long large-diameter portion of the radial blade part 23 of the spherical brush element 20A of hard, high-quality green tea is crooked easily, and sense of touch improves, and in contrast, the outwash effect reduces.But in the cylinder type toothbrush of the 2nd form of implementation, the silk material diameter that is arranged at the spherical brush element 20A of hard on the large-diameter portion is greater than the silk material diameter that is arranged at the spherical brush element 20A of hard on the minor diameter, and thus, the outwash effect is even vertically.In addition, the axial sense of touch of brush 20 is also even.
The cylinder type toothbrush of the 3rd form of implementation as shown in figure 16, the external diameter that is brush 20 is from axial leading section end, the truncated cone shape of Zeng Jiaing at leisure backward.Its shape also cylinder type toothbrush with the 2nd form of implementation is identical, by the external diameter of the spherical brush element 20A of hard, particularly, the variation of the length of radial blade part 23 and realize that the external diameter of soft spherical brush element 20B is certain.
This cylinder type toothbrush not only has the effect of brush 20 for the mixed structure of spherical brush element 20A of hard and soft spherical brush element 20B mixing, and because front end is pointed, so internal tooth is stably scrubbed, in addition, by the long rearward end of high-quality green tea, present the excellent massage effect.
In the cylinder type toothbrush of the 4th form of implementation, as shown in figure 17, brush 20 is drum type, and wherein, its external diameter increases towards both ends at leisure from axial pars intermedia.The cylinder type toothbrush of this shape and the 2nd form of implementation is identical with the cylinder type toothbrush of the 3rd form of implementation, external diameter by the spherical brush element 20A of hard, the variation of the length of particularly radial blade part 23 and realize that the external diameter of soft spherical brush element 20B is certain.
In the present invention, can adopt the brush 20 of such non-linear shapes.
In the cylinder type toothbrush of the 2nd～the 4th form of implementation, the external diameter of the soft spherical brush element 20B in the brush 20 of non-linear shapes is certain, still, can change corresponding to the external diameter such as the spherical brush element 20A of, hard, changes its external diameter.In this occasion, best equally, according in the large-diameter portion side greater than the minor diameter of brush 20, the mode that the diameter difference of spherical brush element 20A of hard and soft spherical brush element 20B increases is careful.
In any occasion, because brush 20 is that external diameter variation because of the spherical brush element 20A of hard causes for the effect of non-linear shapes specially, so can be irrelevant with the shape of soft spherical brush element 20B, and with the irrelevant situation of its existence under obtain, also can obtain to exist the situation of the distance piece beyond the soft spherical brush element 20B.That is, brush 20 is that the effect of non-linear shapes is identical with the effect of the flange part 15 of handle 10, and is for all cylinder type toothbrushes of the brush beyond the brush 20 with mixed structure, all effective.
As the method that constitutes brush 20 at the leading section of handle 10, in the cylinder type toothbrush of the 1st～the 4th form of implementation, minor diameter axial region 12 at handle 10, embed the spherical brush element 20A of hard and the soft spherical brush element 20B of regulation number according to the rules in proper order from front, then, leading section to minor diameter axial region 12 carries out thermoplastic, form ca(u)lk portion 13, between the ca(u)lk portion 13 and retainer 14 of minor diameter axial region 12, be maintained fixed brush 20, but, as shown in figure 18, be to be pre-formed on the leading section on the axis body 10C of large diameter retainer 17, embed spherical brush element 20A of hard and the soft spherical brush element 20B that stipulates number according to the rules in proper order from rear end side, then, the rearward end of this axis body 10C inserted in the patchhole 18 on the front end face that is arranged at handle 10, by heat sealing machine both are fixed, even in this case, still the leading section at handle 10 is maintained fixed brush 20.
As the fixation of axis body 10C, also can adopt the ring-type on the rearward end outer peripheral face that is arranged at its taper, the fitting portion 19 of wedge shape as shown in figure 19.
The soft spherical brush element 20B that is used for brush 20 is the cylinder type toothbrush in above-mentioned form of implementation, from annual disk portion 25, with a plurality of tongue-shaped outstanding radially petal-shaped of planar projection 26, but, also can be as shown in figure 20, be the circumferential shape (in Figure 20, two are arranged at diagonal position) that is provided with according to isogonism in fan-shaped planar projection 26 edges that width enlarges, particularly regardless of its shape.For along the shape that the big planar projection 26 of width circumferentially is set according to isogonism, can be according between soft spherical brush element 20B arranged side by side vertically, the mode that planar projection 26 does not overlap forms the setting of phase difference ground.
