Description

本考案は、理容鋏における枢結軸部分の改良に関するものである。 The present invention relates to the improvement of the pivot axis part in the barber shop.

鋏の基本的構成は、周知の通り一対の刀体をＸ状に交叉させ、両刀体を貫通する軸孔を穿設し、該軸孔に挿通した枢結軸で交叉部を枢結してなるものである。しかも前記枢結軸部分は、軸方向に緩いとスムーズな切断作用を発揮しないので、ある程度強く緊締する必要がある。しかし強く緊締すると刀体の回動がスムーズにならない虞がある。その対策として、強い緊締でも刀体がスムーズに動作するように刀体間に樹脂ワッシャを介装する手段や、樹脂ワッシャの代わりに上下摺動板を備えベアリング体を内装する手段が知られている（特許文献１）。 As is well known, the basic structure of a spear is to cross a pair of swords in an X shape, drill a shaft hole that penetrates both swords, and pivotally connect the crossing part with a pivot shaft inserted through the shaft hole. It will be. Moreover, if the pivot shaft portion is loose in the axial direction, it does not exhibit a smooth cutting action, so it must be tightened to some extent. However, if tightened strongly, the blade may not rotate smoothly. As countermeasures, there are known means for interposing a resin washer between the blades so that the blades can operate smoothly even with strong tightening, and means for installing a bearing body with an upper and lower sliding plate instead of the resin washer. (Patent Document 1).

ベアリング体を介在させる手段は、摩擦抵抗の軽減のみを目的とした樹脂ワッシャよりも刀体回動操作がスムーズになされる。然し上下摺動板を備えベアリング体を採用した場合に、枢結部のベアリング体収納凹部面に切断された毛髪細片が侵入すると、凹部の底面やベアリング体の表面に毛髪細片が付着し易く、特にベアリング球の通過位置の凹部底面に付着すると、毛髪細片が動作部分に介在することになり、その使用感は著しく低下してしまう。 The means for interposing the bearing body allows the blade to rotate more smoothly than the resin washer for the purpose of reducing the frictional resistance. However, when the bearing body is used with the upper and lower sliding plates, if the hair fragment cut into the bearing body housing recess surface of the pivoting portion enters, the hair strip adheres to the bottom surface of the recess or the surface of the bearing body. If it adheres to the bottom face of the concave part at the passing position of the bearing ball, hair strips are interposed in the operating part, and the feeling of use is significantly reduced.

そこで、本願出願人は、内外二重筒体間にベアリング球を介装したベアリング体（筒型ベアリング体）を、枢結部の刀体の対向面に設けた凹部に内装する手段を提案した（特許文献２）。更に前記筒型ベアリング体の内外筒部がそれぞれ対向刀体と容易に共回り接続するように凹部内に所定の突起を設けると共に、筒型ベアリング体にカラー部材を装着する構成も提案した（特許文献３）。 Therefore, the applicant of the present application has proposed a means for interiorizing a bearing body (cylindrical bearing body) in which a bearing ball is interposed between the inner and outer double cylinders in a recess provided on the opposing surface of the blade of the pivoting part. (Patent Document 2). Furthermore, a configuration has been proposed in which a predetermined projection is provided in the recess so that the inner and outer cylindrical portions of the cylindrical bearing body can be easily connected together with the opposing blade body, and a collar member is attached to the cylindrical bearing body (patent) Reference 3).

また筒状ベアリング体を枢結部対向面に設けた凹部内に収納せずに、一方の刀体は貫通孔とし、当該貫通孔と対向面凹部に筒型ベアリング体を収納する構成も提案した（特許文献４）。 In addition, a configuration was proposed in which the cylindrical bearing body is not housed in the concave portion provided on the surface opposite to the pivoting portion, but one of the blades is a through hole, and the cylindrical bearing body is accommodated in the through hole and the opposing surface concave portion. (Patent Document 4).

更に枢結部を連結する枢結ボルト及び締付ナットの頭部の外方への突出を少なくする構造についても提案した（特許文献５）。 Furthermore, the structure which reduces the protrusion to the outward of the head of the pivot bolt and fastening nut which connect a pivot part was proposed (patent document 5).

筒型ベアリング体を採用している特許文献２〜４は、枢結部の締付ナットが突出しており、締付ナットが刀体外方に突出して存在していると、当該突出部分は毛髪との接触の可能性が高くナット下方に毛髪が入り込み、使用後の清掃が煩雑である。また外見上バランスの良い形態とは言えない。 In Patent Documents 2 to 4 adopting a cylindrical bearing body, when the fastening nut of the pivoting portion protrudes and the fastening nut protrudes outward from the blade body, the protruding portion becomes hair and hair. There is a high possibility of contact, and hair enters the lower part of the nut, and cleaning after use is complicated. Moreover, it cannot be said that the form is well balanced in appearance.

また筒型ベアリング体の内外筒部が対向する各刀体と各別に当接して、各々の刀体が内外筒部とそれぞれ共回り構造とするために、刀体の枢結部の凹部の底面を傾斜させたり、小突起を形成するなどの複雑で煩瑣な加工が必要であり、前記の底面傾斜や突起が微妙にずれると、刀体対向面のクリアランスが微妙に変化してしまう。 In addition, the bottom surface of the concave portion of the pivotal portion of the blade body is formed so that the inner and outer cylinder portions of the cylindrical bearing body are in contact with the respective blade bodies facing each other and each blade body has a co-rotating structure with the inner and outer cylinder portions. It is necessary to perform complicated and troublesome processing such as tilting the surface or forming small protrusions. If the bottom surface inclination or the protrusions are slightly deviated, the clearance of the blade-facing surface slightly changes.

また特許文献５の枢結部における枢結ボルト頭部及び締付ナットを刀体に埋没した構造を採用することで、前記の突出ナットの問題は解消されているが、枢結部における刀体の凹部形状が複雑であり、製造上の煩雑さがある。 Further, by adopting a structure in which the pivot bolt head and the fastening nut in the pivot part of Patent Document 5 are buried in the knife, the problem of the protruding nut is solved, but the knife in the pivot part. The shape of the recess is complicated, and there is a complexity in manufacturing.

即ち枢結軸に対して相対的に動作する側の刀体の凹部には、枢結ボルトの頭部が埋没する浅い凹部と、筒型ベアリング体の収納凹部と、枢結軸用丸孔を穿設すると共に、対向刀体のクリアランスを確保するリング状樹脂パッキンの収納凹部を必要とする。 In other words, the concave portion of the blade that moves relative to the pivot shaft includes a shallow concave portion in which the head of the pivot bolt is buried, a storage concave portion of the cylindrical bearing body, and a round hole for the pivot shaft. A recess for storing the ring-shaped resin packing that secures the clearance between the opposing blades is required.

クリアランスを確保するリング状樹脂パッキンが存在しないと、両刀体の対向面が強く当接することになり、ベアリング体を採用してスムーズな開閉操作を行うという利点を殺してしまう結果となる。 If there is no ring-shaped resin packing that secures the clearance, the opposing surfaces of the two blades will come into strong contact with each other, resulting in the advantage of performing a smooth opening / closing operation using a bearing body.

そこで本考案は、筒型ベアリング体を採用した理容鋏において、枢結部の刀体凹部形状の簡素化と、枢結部における刀体対向面のクリアランス確保が容易に行なえる新規な枢結部構造を提案したものである。 Therefore, the present invention is a novel pivoting part that can simplify the shape of the concave part of the sword body of the pivoting part and ensure the clearance of the sword body facing surface at the pivoting part in a barber that employs a cylindrical bearing body. The structure is proposed.

本考案に係る理容鋏は、端部に指孔部を形成した一対の刀体をＸ状に交叉させ、交叉部にベアリング部材を介在させて両刀体を貫通する枢結ボルト及び締付ナットで枢結してなる理容鋏であって、ベアリング部材を、内外二重筒部間にベアリング球を介装した筒型ベアリング体、及び前記筒型ベアリング体における内側筒部に貫通挿着し且つ外側筒部外周より内方位置となるフランジ部を有するカラー体とで形成してなり、枢結ボルトを、カラー体に挿着した際に、頭部底面が筒型ベアリング体の外側筒部端面と当接せず、筒型ベアリング体の外側筒部外周と略一致する大きさで、且つカラー体のフランジ部から突出した軸部を角軸部に形成すると共に、角軸部の先端側に螺軸部に形成し、締付ナットを、前記螺軸部と螺合する袋ナットに形成し、刀体の一方には、外面側から前記ベアリング部材が収納されると共に、対向面側からカラー体のフランジ部が突出し、且つ外側筒部の端面と当接する当接段差を設けた収納孔部を形成し、他方の刀体には、対向面側に突出したカラー体のヒンジ部が当接する当接凹部、及び外面側に締付ナットの収納凹部、及び当接凹部と収納凹部との間に角軸孔を形成し、収納孔部にベアリング部材を収納すると共に、枢結ボルトを挿通し締付ナットを螺合緊締して対向する刀体を枢結してなることを特徴とするものである。 A barber according to the present invention includes a pivot bolt and a tightening nut that cross a pair of blades having finger holes at the ends in an X shape, and through both blades with a bearing member interposed at the intersection. It is a barber made by pivoting, and a bearing member is inserted through and inserted into a cylindrical bearing body having a bearing ball interposed between inner and outer double cylindrical portions, and an inner cylindrical portion of the cylindrical bearing body and It is formed with a collar body having a flange portion located inward from the outer periphery of the cylinder portion, and when the pivot bolt is inserted into the collar body, the bottom surface of the head is the end surface of the outer cylinder portion of the cylindrical bearing body. A shaft portion protruding from the flange portion of the collar body is formed in the angular shaft portion and does not abut and is substantially coincident with the outer periphery of the outer cylindrical portion of the cylindrical bearing body, and is screwed to the distal end side of the angular shaft portion. Formed on the shaft, and the tightening nut is formed into a cap nut that is screwed onto the screw shaft. One side of the blade body accommodates the bearing member from the outer surface side, and a housing hole provided with a contact step where the flange portion of the collar body projects from the opposite surface side and contacts the end surface of the outer cylindrical portion. The other sword body has a contact recess with which the hinge portion of the collar body protruding toward the opposing surface abuts, a storage recess of the tightening nut on the outer surface side, and a contact recess and a storage recess. A rectangular shaft hole is formed in between, and a bearing member is housed in the housing hole, and a pivoting bolt is inserted, a tightening nut is screwed and tightened, and the opposing blades are pivoted. Is.

また第二の考案（請求項２）は、前記の第一の考案において、筒型ベアリング体の外側筒部にフランジ筒部を設け、刀体の収納孔部の底方の当接段差を、表面側の筒型ベアリング体のヒンジ筒部が当接する当接段差としたものである。 A second device (Claim 2) is the above-mentioned first device, wherein a flange tube portion is provided on the outer tube portion of the cylindrical bearing body, and the contact step at the bottom of the storage hole portion of the blade body is provided. This is a contact step where the hinge cylinder part of the cylindrical bearing body on the surface side contacts.

然して枢結ボルトに締付ナットを螺合して緊締すると、筒型ベアリング体の外側筒部と当接する一方の刀体（当接段差を備えた刀体）と、筒型ベアリング体の内側筒部、カラー体、枢結ボルト、締付ナットと共回りする刀体との相対的回動は、筒型ベアリング体を介在することになり、また両刀体の対向面のクリアランスは、外側筒部と刀体の当接段差との当接、並びにカラー体の他方刀体の当接凹部の当接によって確実に確保されることになり、鋏作用をなす刀体の開閉操作はスムーズに行なわれることになる。 However, when the tightening nut is screwed onto the pivot bolt and tightened, one sword (a sword having a contact step) that contacts the outer cylinder of the cylindrical bearing body and the inner cylinder of the cylindrical bearing body The relative rotation of the blade body, the collar body, the pivot bolt, and the knife that rotates together with the tightening nut interposes the cylindrical bearing body, and the clearance between the opposing surfaces of both blade bodies is the outer cylinder portion. The contact between the blade and the contact step of the blade and the contact of the contact recess of the other blade of the collar body are surely secured, and the opening / closing operation of the blade that performs the scissors action is performed smoothly. It will be.

本考案は上記構成を採用したことによって、筒型ベアリング体を採用した理容鋏において、枢結部の刀体凹部形状が、一方の刀体は段差を備えた貫通孔（収納孔部）であり、他方刀体においては、表裏に凹部（当接凹部と収納凹部）を形成するのみであり、製造加工においては、段差位置の掘削深さと、当接凹部の掘削深さの一定の加工調整のみで所望の対向面クリアランスを得ることができ、また枢結部における枢結ボルト頭部及び締付ナットを刀体に埋没した構造を容易に製造できたものである。 The present invention adopts the above-described configuration, so that in the barber adopting the cylindrical bearing body, the shape of the sword body recess of the pivoting part is one through hole (storage hole part) provided with a step. On the other hand, the sword body only has recesses (abutting recesses and storage recesses) formed on the front and back sides, and in manufacturing processing, only a fixed adjustment of the excavation depth at the step position and the excavation depth of the abutting recess. Thus, a desired opposing surface clearance can be obtained, and a structure in which the pivot bolt head and the fastening nut in the pivot portion are buried in the blade can be easily manufactured.

次に本考案の実施形態について説明する。図１乃至図５は本考案の第一実施形態で、その理容鋏の基本的構成は、一対の刀体１，２と、ベアリング部材３と、枢結ボルト４と、締付ナット５とで構成される。 Next, an embodiment of the present invention will be described. 1 to 5 show a first embodiment of the present invention. The basic structure of the barber is composed of a pair of blades 1 and 2, a bearing member 3, a pivot bolt 4 and a tightening nut 5. Composed.

刀体１，２は従前の理容鋏と同様にＸ状に交叉させ、交叉部を枢結するもので、刀体１，２の一方は刃部１１，１２とし、他方端部には指孔１２，２２を形成したものである。そして刀体１の交叉部対向面（枢結部）に、ベアリング部材３と、枢結ボルト４と、締付ナット５を装着収納する凹部や孔部を形成したものである。 The swords 1 and 2 are crossed in an X shape like the conventional barber, and the crossing parts are pivoted. One of the swords 1 and 2 is the blade parts 11 and 12, and the other end is a finger hole. 12 and 22 are formed. And the recessed part and hole which mount and store the bearing member 3, the pivot bolt 4, and the fastening nut 5 are formed in the crossing part opposing surface (pivot part) of the sword 1.

枢結部における一方の刀体１には、外面側からベアリング部材３が収納される収納孔部１３を形成すると共に、収納孔部１３の底方の周壁に、周壁より小径となる当接段差１４を設けてなる。 One blade body 1 in the pivot portion is formed with a storage hole portion 13 in which the bearing member 3 is stored from the outer surface side, and a contact step having a smaller diameter than the peripheral wall on the peripheral wall at the bottom of the storage hole portion 13. 14 is provided.

また他方の刀体２には、対向面側に後述するカラー体３４のフランジ部３５が当接する当接凹部２３を形成し、外面側に締付ナット５の収納凹部２４を形成し、更に前記当接凹部２３と収納凹部２４との間に角軸孔２５を形成してなる。 The other sword body 2 is formed with an abutting recess 23 in which a flange portion 35 of a collar body 34, which will be described later, abuts on the opposite surface side, and an accommodation recess 24 of a tightening nut 5 is formed on the outer surface side. An angular shaft hole 25 is formed between the contact recess 23 and the storage recess 24.

ベアリング部材３を、筒型ベアリング体３０とカラー体３４で構成され、筒型ベアリング体３０は、内外二重筒部３１，３２間にベアリング球３３を介装したものであり、カラー体３４は、前記筒型ベアリング体３０における内側筒部３１に貫通挿着し且つ外側筒部３２の外周より内方位置となるフランジ部３５を備えるものである。 The bearing member 3 includes a cylindrical bearing body 30 and a collar body 34. The cylindrical bearing body 30 includes a bearing ball 33 interposed between the inner and outer double cylindrical portions 31 and 32. The flange portion 35 is provided so as to pass through the inner cylindrical portion 31 of the cylindrical bearing body 30 and to be inward from the outer periphery of the outer cylindrical portion 32.

またその大きさは、前記収納孔部１３と対応する外径で、且つ後述する枢結ボルト４を装着して刀体１の収納孔部１３に装着した際（外側筒部３２が当接段差１４に当接した状態）に、枢結ボルト４の頭部４１が収納孔部１３より外方に突出しないか、或いは僅かに突出する程度の大きさで、更に対向面側からカラー体３４のフランジ部３５が適宜長突出する大きさに形成したものである。 Further, the outer diameter thereof corresponds to the storage hole portion 13 and when the pivot bolt 4 described later is attached to the storage hole portion 13 of the blade body 1 (the outer cylindrical portion 32 is in contact with the contact step). 14 in a state in which the head 41 of the pivot bolt 4 does not protrude outward from the housing hole 13 or slightly protrudes, and further from the opposite surface side of the collar body 34. The flange portion 35 is formed so as to protrude appropriately.

枢結ボルト４は、所定の頭部４１と、丸軸部４２と、角軸部４３と、螺軸部４４を備えてなり、頭部４１は、ベアリング部材３のカラー体３４に挿着した際に、筒型ベアリング体３０の外側筒部３２の上端面と当接しない形状で、且つ筒型ベアリング体３０の外側筒部３２の外周と略一致する大きさとしたものである。 The pivot bolt 4 includes a predetermined head 41, a round shaft portion 42, a square shaft portion 43, and a screw shaft portion 44, and the head portion 41 is attached to the collar body 34 of the bearing member 3. In this case, the cylindrical bearing body 30 has a shape that does not come into contact with the upper end surface of the outer cylindrical portion 32, and has a size that substantially coincides with the outer periphery of the outer cylindrical portion 32 of the cylindrical bearing body 30.

また丸軸部４２は、カラー体３４の貫通孔に密挿される大きさとし、角軸部４３は、角軸孔２５と対応する形状で、角軸部４３の先端側を螺軸部４４に形成したものである。 The round shaft portion 42 is sized to be closely inserted into the through hole of the collar body 34, and the square shaft portion 43 has a shape corresponding to the square shaft hole 25, and the tip end side of the square shaft portion 43 is formed in the screw shaft portion 44. It is a thing.

締付ナット５は、刀体２の収納凹部２４に対応するする大きさで、前記螺軸部４４と螺合する袋ナットである。 The tightening nut 5 is a cap nut having a size corresponding to the storage recess 24 of the blade 2 and screwed into the screw shaft portion 44.

而して枢結ボルト４をベアリング部材３に挿着し、ベアリング部材３を収納孔部１３内に収納し、外側筒部３２の下端を当接段差１４に当接し、刀体１の対向面から突出したカラー体３４のフランジ部３５を、対向する刀体２の当接凹部２３に入れ込み、枢結ボルト４の螺軸部４４を締付ナット５の収納凹部２４内に突出させて、締付ナット５を螺合装着する。 Thus, the pivot bolt 4 is inserted into the bearing member 3, the bearing member 3 is accommodated in the accommodation hole 13, the lower end of the outer cylindrical portion 32 abuts against the abutting step 14, and the opposing surface of the blade 1 The flange portion 35 of the collar body 34 projecting from the shaft is inserted into the contact recess 23 of the opposing blade body 2, and the screw shaft portion 44 of the pivot bolt 4 is projected into the housing recess 24 of the tightening nut 5 to tighten it. The attached nut 5 is screwed and attached.

そこで締付ナット５を緊締すると、当接段差１４と外側筒部３２が当接し、カラー体３４のフランジ部３５と当接凹部２３が当接し、各当接箇所は、各々密着状態となり、刀体１，２の対向面のクリアランスＡが自然に定まる。 When the tightening nut 5 is tightened, the contact step 14 and the outer cylindrical portion 32 come into contact with each other, the flange portion 35 of the collar body 34 and the contact recess 23 come into contact with each other. The clearance A between the opposing surfaces of the bodies 1 and 2 is naturally determined.

そして一方の刀体１は、筒型ベアリング体３０の外側筒部３２と当接段差１４を介して連結状態となり、他方の刀体２は、角軸孔２５への角軸部４３の挿着（枢結ボルト４の連結）、並びにベアリング体３０の内側筒部３１、カラー体３４、締付ナット５と連結状態となり、両刀体１，２との相対的回動（開閉操作）は、筒型ベアリング体３０のベアリング球３３を介在することになり、スムーズに行なわれることになる。 One blade 1 is connected to the outer cylindrical portion 32 of the cylindrical bearing body 30 via the contact step 14, and the other blade 2 is attached to the square shaft hole 25 in the angular shaft portion 43. (Connection of the pivot bolt 4) and the inner cylinder portion 31, the collar body 34, and the tightening nut 5 of the bearing body 30 are connected to each other, and the relative rotation (opening and closing operation) between the two blade bodies 1 and 2 is performed by the cylinder. The bearing ball 33 of the mold bearing body 30 is interposed, so that smooth operation is performed.

更に枢結ボルト４の頭部４１は、収納孔部１３に納まるか、或いは僅かに外方に突出し、また締付ナット５も、めくらナットとしてその全体の殆どが収納凹部２４内に収納されることになり、枢結軸部分の外方突出を小さくでき、刀体表裏のバランスを良くしたものである。 Further, the head 41 of the pivot bolt 4 is accommodated in the accommodation hole 13 or slightly protrudes outward, and the tightening nut 5 is mostly accommodated in the accommodation recess 24 as a blind nut. As a result, the outward protrusion of the pivot shaft portion can be reduced, and the balance between the front and back of the blade is improved.

図６乃至図８は本考案の第二実施形態で、基本的には第一実施形態と同様な構成を具備したもので、相違する箇所は、刀体１の収納孔部１３における当接段差１４ａと、当該当接段差１４ａに採用にともなって、ベアリング部材３ａの筒型ベアリング体３０ａの構造と、枢結ボルト４ａの頭部４１ａが相違するもので、その他の構造は第一実施形態と同一である（図面の指示番号が一致する箇所は同一構造であり、その説明は省略した）。 6 to 8 show a second embodiment of the present invention, which basically has the same configuration as that of the first embodiment. The difference is the contact step in the storage hole 13 of the blade 1. 14a and the contact step 14a, the structure of the cylindrical bearing body 30a of the bearing member 3a is different from the head 41a of the pivot bolt 4a. Other structures are the same as those of the first embodiment. They are the same (the parts with the same designation numbers in the drawings have the same structure, and the explanation is omitted).

刀体１の収納凹部２４は、ベアリング部材３ａが収納される形状に形成すると共に、収納孔部１３の上方の周壁適宜位置に、周壁より大径となる当接段差１４ａを設けてなるものである。 The storage recess 24 of the blade 1 is formed in a shape in which the bearing member 3a is stored, and is provided with a contact step 14a having a larger diameter than the peripheral wall at an appropriate position on the peripheral wall above the storage hole 13. is there.

またベアリング部材３ａの筒型ベアリング体３０ａは、外側筒部３２の上端に、前記当接段差１４ａと対応するフランジ筒部３６を設けてなるものである。 The cylindrical bearing body 30a of the bearing member 3a is provided with a flange cylinder portion 36 corresponding to the contact step 14a at the upper end of the outer cylinder portion 32.

更に枢結ボルト４ａにおいては、その頭部４１ａを、フランジ筒部３６の上方を覆う形状に形成したものである。 Further, in the pivot bolt 4a, the head portion 41a is formed in a shape that covers the upper side of the flange tube portion 36.

而して枢結ボルト４ａをベアリング部材３ａに挿着し、両刀体１，２の枢結箇所に装着し、枢結ボルト４ａの螺軸部４４に締付ナット５を螺合装着すると、フランジ筒部３６が当接段差１４ａに当接して装着されることになる。 Thus, when the pivoting bolt 4a is inserted into the bearing member 3a, mounted at the pivotal positions of the two blades 1, 2, and the tightening nut 5 is screwed onto the screw shaft portion 44 of the pivotal bolt 4a, the flange is The cylindrical portion 36 is attached in contact with the contact step 14a.

従って締付ナット５の螺合緊締によって、当接段差１４ａと外側筒部３２のフランジ筒部３６が当接し、カラー体３４のフランジ部３５と当接凹部２３の当接することになり、当該当接箇所が各々密着状態となって、刀体１，２の対向面のクリアランスＡが自然に定まることなる。このように第一実施形態と同様に所定のクリアランスを備えることで、両刀体１，２との相対的回動（開閉操作）は、ベアリング体３０ａによってスムーズに行なわれることになる。 Accordingly, the screwing tightening of the tightening nut 5 causes the contact step 14a and the flange tube portion 36 of the outer tube portion 32 to contact, and the flange portion 35 of the collar body 34 and the contact recess 23 contact each other. The contact portions are in close contact with each other, and the clearance A between the opposing surfaces of the blades 1 and 2 is naturally determined. As described above, by providing a predetermined clearance as in the first embodiment, the relative rotation (opening / closing operation) between the two blades 1 and 2 is smoothly performed by the bearing body 30a.

また枢結ボルト４ａの頭部４１ａは、前記のフランジ筒部３６の上方を覆うもので、外観的に、また毛髪の侵入を防ぐ効果を備えるものである。 The head 41a of the pivot bolt 4a covers the upper portion of the flange tube 36, and has an effect of preventing hair from entering in appearance.

尚前記実施形態においては、特に螺軸部４４への締付ナット５の螺合に板バネ体を介在させていないが、特に排除しているものではなく、板バネ体を介在させても良い。この場合には、クリアランスＡは所定間隔を保持するが、軸方向においた対向面間を広げる方向（クリアランスを大きくする方向）に不測の力が作用した場合に、当該力を逃がす作用を奏することになる。 In the above embodiment, the leaf spring body is not particularly interposed in the screwing of the tightening nut 5 to the screw shaft portion 44. However, the leaf spring body is not particularly excluded, and a leaf spring body may be interposed. . In this case, the clearance A maintains a predetermined interval, but when an unexpected force is applied in the direction in which the distance between the opposing surfaces in the axial direction is increased (direction in which the clearance is increased), the clearance A has an effect of releasing the force. become.
