本発明の実施形態１を図１ないし図６によって説明する。本実施形態のバッテリーターミナル１０は、導電性の金属板材によって形成され、バッテリーポストＰに取り付けられる電極保持部１１と、電極保持部１１の前端１１Ａ（本発明における「一端」に相当）から前方（図４の左方に相当）に延出するベース部２０と、電極保持部１１に被せ付けられてこの電極保持部１１を締め付け可能な締付部３０とを備える。電極保持部１１とベース部２０とは一体に成形され、締付部３０はこれらとは別部品として構成される。 <Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. The battery terminal 10 of the present embodiment is formed of a conductive metal plate material, and has an electrode holding part 11 attached to the battery post P, and a front end (corresponding to “one end” in the present invention) from the front end 11A of the electrode holding part 11 ( 4 is provided with a base portion 20 extending to the left of FIG. 4 and a tightening portion 30 that is attached to the electrode holding portion 11 and can tighten the electrode holding portion 11. The electrode holding part 11 and the base part 20 are integrally formed, and the fastening part 30 is configured as a separate part.

バッテリーポストＰは、自動車等に搭載されるバッテリーに突設された電極であって、主に鉛を素材として上端側へ向けて次第に径の小さくなったテーパ状の円柱形に形成されている。   The battery post P is an electrode protruding from a battery mounted on an automobile or the like, and is formed in a tapered cylindrical shape whose diameter gradually decreases toward the upper end side mainly using lead.

電極保持部１１は、図１に示すように、バッテリーポストＰの外周面に沿って回曲する弧状をなし、ベース部２０が配設される側となる前面側には上下方向の全域に亘って開口部１２が形成されている。電極保持部１１の上下方向略中央部には、この電極保持部１１の周方向に延びるスリット１３が形成されており、このスリット１３は、その一端が開口部１２の両側縁に開口し、開口部１２を挟んで左右一対が対称に配されている。したがって、電極保持部１１におけるスリット１３を挟んだ上側領域（本発明における「スリットを挟んでベース部側とは反対側の領域」に相当）は、下側領域よりも内外に撓み変形し易い構造となっている。 As shown in FIG. 1, the electrode holding portion 11 has an arc shape that turns around the outer peripheral surface of the battery post P, and extends across the entire vertical direction on the front surface side on which the base portion 20 is disposed. Thus, an opening 12 is formed. A slit 13 extending in the circumferential direction of the electrode holding portion 11 is formed at a substantially central portion in the vertical direction of the electrode holding portion 11. One end of the slit 13 opens at both side edges of the opening portion 12. A pair of left and right sides are arranged symmetrically with respect to the portion 12. Therefore, the upper region (corresponding to the “region opposite to the base portion across the slit” in the present invention) sandwiching the slit 13 in the electrode holding portion 11 is more easily bent and deformed inward and outward than the lower region. It has become.

電極保持部１１の後端１１Ｂ（本発明における「他端」に相当）の外面上端部には、後方へ向けて突出する抜け止め突部１５が形成されている。抜け止め突部１５は、方形ブロック状をなし、電極保持部１１の板厚と略同一の突出寸法をもって構成されている。この抜け止め突部１５には、後述する締付部３０の受け部３３が嵌入可能とされる。   At the upper end of the outer surface of the rear end 11 </ b> B (corresponding to “the other end” in the present invention) of the electrode holding portion 11, a retaining protrusion 15 that protrudes rearward is formed. The retaining protrusion 15 has a rectangular block shape and is configured to have a protruding dimension substantially the same as the plate thickness of the electrode holding portion 11. A receiving portion 33 of a tightening portion 30 to be described later can be fitted into the retaining protrusion 15.

ベース部２０は、前後方向を開放させた箱形をなし、電極保持部１１の前面下端部から前方へ突出して形成されている。詳しくは、ベース部２０は、電極保持部１１の開口部１２の両側縁下端部に連結されて上下方向に切り立つよう対向に配された両側板２１と、両側板２１の下端から内側に直角曲げされてその端縁２２Ａ同士を離間させた左右一対の下板２２と、両側板２１の上端から内側に直角曲げされてその端縁２３Ａ同士を前後方向に沿って突き合わせた左右一対の上板２３とからなる。   The base portion 20 has a box shape with the front-rear direction opened, and is formed to protrude forward from the lower end portion of the front surface of the electrode holding portion 11. Specifically, the base portion 20 is connected to the lower end portions on both side edges of the opening portion 12 of the electrode holding portion 11 and arranged oppositely so as to stand up and down, and is bent at right angles from the lower ends of the both side plates 21 to the inside. The pair of left and right lower plates 22 with their edges 22A spaced apart from each other, and the pair of left and right upper plates 23 bent at right angles from the upper ends of the side plates 21 to face each other along the front and rear direction. It consists of.

上板２３の突き合わせ縁２３Ａはベース部２０の幅方向略中央部に配されており、ここに各端縁２３Ａに開口する半円弧部２３Ｂが合致することにより、ボルト２６の軸部２６Ｂの根元部分を挿通可能な略円形のボルト挿通孔２５が形成される。また、図５に示すように、ベース部２０の内側はボルト２６の頭部２６Ａを収容してボルト２６を起立状態で支持するための支持空間２４となっている。したがって、ボルト２６は、その頭部２６Ａが上板２３と下板２２との間に挟持された状態で支持空間内２４に固定され、かつ、その軸部２６Ｂがボルト挿通孔２５から上方へ向けて突出した状態で配置される。   The abutting edge 23A of the upper plate 23 is arranged at a substantially central portion in the width direction of the base portion 20, and a semicircular arc portion 23B opened to each end edge 23A is aligned therewith, whereby the base of the shaft portion 26B of the bolt 26 is obtained. A substantially circular bolt insertion hole 25 through which the portion can be inserted is formed. Further, as shown in FIG. 5, the inner side of the base portion 20 is a support space 24 for accommodating the head portion 26A of the bolt 26 and supporting the bolt 26 in an upright state. Therefore, the bolt 26 is fixed to the support space 24 in a state where the head portion 26A is sandwiched between the upper plate 23 and the lower plate 22, and the shaft portion 26B is directed upward from the bolt insertion hole 25. It is arranged in a protruding state.

締付部３０は、全体として概ね前方後円形状をなし、上方から電極保持部１１に被せ付けられる略環状の締め輪部３１と、締め輪部３１の前端から前方へ延出してベース部２０上に対向に配される略方形板状のアーム部３２とから構成される。   The tightening portion 30 has a generally front and rear circular shape as a whole. The tightening portion 30 extends substantially forward from the front end of the tightening ring portion 31 and the base portion 20. It is comprised from the substantially rectangular plate-shaped arm part 32 distribute | arranged facing upwards.

アーム部３２の略中央部には、ベース部２０側から突出するボルト２６の軸部２６Ｂを遊嵌状態で貫通させるボルト通し孔３４が形成されている。ボルト２６の軸部２６Ｂの先端部分は、図２に示すように、ボルト通し孔３４から上方に突出しており、この先端部分にナット２７が螺合し、さらにナット２７の座面２７Ａがアーム部３２の上面におけるボルト通し孔３４の孔縁部に係合するようになっている。   A bolt through hole 34 is formed at a substantially central portion of the arm portion 32 to allow the shaft portion 26B of the bolt 26 protruding from the base portion 20 side to pass through in a loosely fitted state. As shown in FIG. 2, the front end portion of the shaft portion 26B of the bolt 26 protrudes upward from the bolt through hole 34, the nut 27 is screwed into the front end portion, and the seat surface 27A of the nut 27 is the arm portion. It engages with the hole edge of the bolt through hole 34 on the upper surface of 32.

アーム部３２の前端下面略中央部には、ボルト２６にナット２７が過度締めされるのを防止するための過度締付防止片３５が延出して形成されている。過度締付防止片３５は、図４に示すように、アーム部３２が略水平姿勢をとるときに、アーム部３２の前端下面略中央部から垂下される垂直部３５Ａと、その下端から後方へ向けて延出する水平部３５Ｂとからなり、この水平部３５Ｂと垂直部３５Ａとにより全体として略Ｌの字をなしている。   An over-tightening prevention piece 35 for preventing the nut 27 from being over-tightened to the bolt 26 is formed at a substantially central portion of the lower surface of the front end of the arm portion 32. As shown in FIG. 4, the over-tightening prevention piece 35 includes a vertical portion 35 </ b> A that hangs down from a substantially central portion of the lower surface of the front end of the arm portion 32 when the arm portion 32 assumes a substantially horizontal posture, and a rear side from the lower end thereof. The horizontal portion 35B extends toward the surface, and the horizontal portion 35B and the vertical portion 35A form a substantially L shape as a whole.

締め輪部３１は、その内径寸法が電極保持部１１の先端側１１Ｃの外径寸法と基端側１１Ｅの外径寸法との間の大きさに設定されており、電極保持部１１の上下方向途中位置に嵌着可能となっている。また、締め輪部３１には、図２に示すように、その最後端位置から周方向に少しずれた位置に、受け部３３が形成されている。受け部３３は、図３に示すように、外向きに膨出する略門型枠状をなし、その内側に抜け止め突部１５を嵌入したあと周方向にずらされることで、その隣接領域３３Ａに抜け止め突部１５を係止させるようになっている。受け部３３の隣接領域３３Ａと抜け止め突部１５とが締付部３０の抜け方向で掛止し合うことにより、締付部３０の電極保持部１１からの抜け出しが防止される。   The inner diameter dimension of the fastening ring part 31 is set to a size between the outer diameter dimension of the distal end side 11C and the outer diameter dimension of the proximal end side 11E of the electrode holding part 11, and the vertical direction of the electrode holding part 11 It can be fitted in the middle position. Further, as shown in FIG. 2, the fastening ring portion 31 is formed with a receiving portion 33 at a position slightly deviated from the rear end position in the circumferential direction. As shown in FIG. 3, the receiving portion 33 has a substantially gate-shaped frame shape that bulges outward, and after the retaining protrusion 15 is fitted inside the receiving portion 33, the receiving portion 33 is shifted in the circumferential direction, thereby adjacent region 33 </ b> A. The retaining protrusion 15 is engaged with the stopper. The adjacent region 33A of the receiving portion 33 and the retaining protrusion 15 are engaged with each other in the direction in which the tightening portion 30 is detached, so that the tightening portion 30 is prevented from coming off from the electrode holding portion 11.

ここで、アーム部３２に対してナット２７の押圧力が作用していないときには、受け部３３の隣接領域３３Ａと抜け止め突部１５とが掛止し合うとともに、これと同じ高さ位置にアーム部３２が略水平な姿勢で連なるようになっている（図４を参照）。一方、アーム部３２に対してナット２７の押圧力が作用したときには、受け部３３の隣接領域３３Ａと抜け止め突部１５とが掛止し合う位置３６をてこ支点としてアーム部３２が下方へ傾倒するようになっている（図６を参照）。そして、アーム部３２の傾倒動作に連れ立って締め輪部３１の内縁３１Ａが下方へ変位することになり、この変位動作に伴って電極保持部１１が開口部１２の幅寸法を狭めるように縮径変形され、もってバッテリーターミナル１０がバッテリーポストＰを締め付けるようになっている。   Here, when the pressing force of the nut 27 does not act on the arm portion 32, the adjacent region 33A of the receiving portion 33 and the retaining projection 15 are engaged with each other, and the arm is positioned at the same height position. The parts 32 are arranged in a substantially horizontal posture (see FIG. 4). On the other hand, when the pressing force of the nut 27 acts on the arm portion 32, the arm portion 32 tilts downward with the position 36 where the adjacent region 33 </ b> A of the receiving portion 33 is engaged with the retaining projection 15 as a lever fulcrum. (See FIG. 6). Then, the inner edge 31A of the fastening ring portion 31 is displaced downward along with the tilting operation of the arm portion 32, and the diameter of the electrode holding portion 11 is reduced so that the width dimension of the opening 12 is narrowed along with this displacement operation. As a result, the battery terminal 10 tightens the battery post P.

次に、本実施形態の作用を説明する。まず、展開状態にあるベース部２０に対し、下板２２の上面中央部２２Ｂにボルト２６の頭部２６Ａを載せてボルト２６を起立させ、その状態で両側板２１を立て上げたあとその立ち上げ端を内向きに折り曲げて上板２３を形成し、その曲げ動作に伴って形成されるボルト挿通孔２５の内側にボルト２６の軸部２６Ｂの根元部分を嵌め入れる。   Next, the operation of this embodiment will be described. First, with respect to the base part 20 in the unfolded state, the head 26A of the bolt 26 is placed on the center part 22B of the upper surface of the lower plate 22 to raise the bolt 26. The upper plate 23 is formed by bending the end inward, and the base portion of the shaft portion 26B of the bolt 26 is fitted inside the bolt insertion hole 25 formed along with the bending operation.

続いて、アーム部３２を上方に持ち上げた状態で受け部３３に抜け止め突部１５を嵌入させ、その状態で締め輪部３１を周方向にずらして抜け止め突部１５に受け部３３の隣接領域３３Ａを掛止させ、さらにアーム部３２を引き下げて略水平姿勢となし、ボルト通し孔３４にボルト２６の軸部２６Ｂの先端部分を嵌め入れる。こうして締付部３０を初期位置にセットしたら、今度はボルト通し孔３４から突出するボルト２６の軸部２６Ｂの先端部分にナット２７を緩くねじ込み、その状態でバッテリーポストＰに対する組み付け現場に移送する（図２及び図３を参照）。   Subsequently, the retaining projection 15 is fitted into the receiving portion 33 in a state where the arm portion 32 is lifted upward, and in this state, the fastening ring portion 31 is shifted in the circumferential direction so that the retaining projection 15 is adjacent to the receiving portion 33. The region 33A is hooked, and the arm portion 32 is further lowered to form a substantially horizontal posture, and the tip portion of the shaft portion 26B of the bolt 26 is fitted into the bolt through hole 34. When the tightening portion 30 is set to the initial position in this way, the nut 27 is loosely screwed into the tip end portion of the shaft portion 26B of the bolt 26 protruding from the bolt through hole 34 and transferred to the assembly site for the battery post P in this state ( (See FIGS. 2 and 3).

組み付け現場においては、バッテリーポストＰに電極保持部１１を上方から被せ付け、次いでボルト２６に対してナット２７を深くねじ込むようにする。すると、ナット２７の座面２７Ａがアーム部３２の上面３２Ａを押圧してアーム部３２が下方へ傾動し、これに伴って締め輪部３１の内縁３１Ａが電極保持部１１の外周面に沿って下方へ変位する。このとき、締め輪部３１の内縁３１Ａが、受け部３３の隣接領域３３Ａと抜け止め突部１５との係合位置３６をてこ支点とする回動軌跡を描きながら電極保持部１１の外周面を摺動することになり、これにより電極保持部１１が次第に縮径変形してバッテリーポストＰに対する締め付け力を高めて行く。そして、ボルト２６に対してナット２７が正規深さでねじ込まれると、アーム部３２が、左下がりの所定角度をもって傾斜するとともに、電極保持部１１が適度な締め付け力をもってバッテリーポストＰに取り付けられる（図６を参照）。この場合に、ナット２７を過度にねじ込もうとしても、過度締付防止片３５がベース部２０と当接してそれ以上のねじ込み動作を阻止するから、ナット２７による過度の締め付けを防止できる。   At the assembly site, the electrode holder 11 is placed on the battery post P from above, and then the nut 27 is screwed deeply into the bolt 26. Then, the seat surface 27 </ b> A of the nut 27 presses the upper surface 32 </ b> A of the arm portion 32, and the arm portion 32 tilts downward. As a result, the inner edge 31 </ b> A of the fastening ring portion 31 extends along the outer peripheral surface of the electrode holding portion 11. Displaces downward. At this time, the inner edge 31 </ b> A of the fastening ring portion 31 draws a rotation trajectory having the engaging position 36 between the adjacent region 33 </ b> A of the receiving portion 33 and the retaining projection 15 as a lever fulcrum, and the outer peripheral surface of the electrode holding portion 11. As a result, the electrode holding portion 11 is gradually reduced in diameter to increase the tightening force on the battery post P. Then, when the nut 27 is screwed into the bolt 26 at a normal depth, the arm portion 32 is inclined at a predetermined angle that is lowered to the left, and the electrode holding portion 11 is attached to the battery post P with an appropriate tightening force ( (See FIG. 6). In this case, even if the nut 27 is to be screwed excessively, the excessive tightening prevention piece 35 abuts against the base portion 20 and prevents further screwing operation, so that excessive tightening by the nut 27 can be prevented.

このように本実施形態によれば、ナット２７によってアーム部３２を押し込むことにより、受け部３３の隣接領域３３Ａと抜け止め突部１５との係合位置３６をてこ支点としてアーム部３２を下方へ傾動させるとともに、このてこ支点とアーム部３２との間に配された締め輪部３１の内縁３１Ａを電極保持部１１の外周面に沿って下方へ変位させ、この変位動作に伴って電極保持部１１を縮径変形させるから、ナット２７とアーム部３２との係合位置３７を力点、締め輪部３１の内縁３１Ａと電極保持部１１の外周面との係合位置３８を作用点とするてこを構成することになり、低い操作力をもってバッテリーポストＰを締め付けることができ、締付トルクのロスの低減を図ることができる。   As described above, according to the present embodiment, by pushing the arm portion 32 with the nut 27, the arm portion 32 is moved downward with the engaging position 36 between the adjacent region 33 </ b> A of the receiving portion 33 and the retaining projection 15 as a lever fulcrum. In addition to tilting, the inner edge 31A of the fastening ring portion 31 disposed between the lever fulcrum and the arm portion 32 is displaced downward along the outer peripheral surface of the electrode holding portion 11, and the electrode holding portion is associated with the displacement operation. 11, the engaging position 37 between the nut 27 and the arm portion 32 is a force point, and the engaging position 38 between the inner edge 31A of the fastening ring portion 31 and the outer peripheral surface of the electrode holding portion 11 is an action point. Thus, the battery post P can be tightened with a low operating force, and the loss of tightening torque can be reduced.

また、電極保持部１１には、この電極保持部１１の周方向に延びるスリット１３が形成されているから、スリット１３を挟んだ上側領域が撓み変形し易くなり、この上側領域に係合される締め輪部３１に過大な締め付け力が必要とされない。その結果、一層低い操作力でバッテリーポストＰを締め付けることができる。 Moreover, since the slit 13 extending in the circumferential direction of the electrode holding portion 11 is formed in the electrode holding portion 11, the upper region sandwiching the slit 13 is easily bent and deformed, and is engaged with the upper region. An excessive tightening force is not required for the tightening ring portion 31. As a result, the battery post P can be tightened with a lower operating force.

＜実施形態２＞
次に、本発明の実施形態２を図７ないし図１３によって説明する。実施形態２では、締付部３０を含みつつ一体成形された締付ユニット４０が備わる点で実施形態１とは異なる。その他は、実施形態１と共通する部分が多いので、同じ構造部位には同一符号を付し、重複する説明は省略する。 <Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment is different from the first embodiment in that a tightening unit 40 that is integrally formed with the tightening portion 30 is provided. In other respects, since there are many parts in common with the first embodiment, the same reference numerals are given to the same structural parts, and duplicate descriptions are omitted.

実施形態２の電極保持部１１の開口部１２は、図８に示すように、ベース部２０の配設位置から周方向に位置ずれした電極保持部１１の一側面１１Ｃに配置され、その両側縁にはスリット１３の一端が臨んでいる。また、実施形態２のベース部２０は、略方形板状をなし、その略中央部に形成されたボルト挿通孔２５の孔壁には雌ねじが切られている。さらに、実施形態２には、抜け止め突部１５に相当するものが設けられていない。   As shown in FIG. 8, the opening 12 of the electrode holding unit 11 according to the second embodiment is disposed on one side surface 11 </ b> C of the electrode holding unit 11 that is displaced in the circumferential direction from the position where the base unit 20 is disposed. One end of the slit 13 faces. Further, the base portion 20 of the second embodiment has a substantially square plate shape, and a female thread is cut in a hole wall of a bolt insertion hole 25 formed in a substantially central portion thereof. Further, the second embodiment is not provided with an equivalent to the retaining projection 15.

締付ユニット４０は、図９に示すように、締付部３０と載置部４１と両者を連結する支持部４５とからなる。締付部３０の形態は、締め輪部３１に受け部３３が形成されていない点を除き、実施形態１と略同一である。また、載置部４１は、ベース部２０上に載置されるものであって、電極保持部１１の基端側１１Ｅを嵌入可能な略環状の取付部４２と、取付部４２の基端側の前面から前方へ突出する略方形板状の載置本体部４３とを備え、取付部４２が締め輪部３１と対向する位置に配置され、載置本体部４３がアーム部３２と対向する位置に配置されている。   As shown in FIG. 9, the tightening unit 40 includes a tightening portion 30, a placement portion 41, and a support portion 45 that couples both. The form of the fastening part 30 is substantially the same as that of the first embodiment except that the receiving part 33 is not formed on the fastening ring part 31. The mounting portion 41 is mounted on the base portion 20 and has a substantially annular mounting portion 42 into which the proximal end side 11E of the electrode holding portion 11 can be fitted, and a proximal end side of the mounting portion 42 A substantially rectangular plate-like mounting main body 43 protruding forward from the front surface of the lens, the mounting portion 42 is disposed at a position facing the fastening ring 31, and the mounting main body 43 is opposed to the arm portion 32. Is arranged.

取付部４２の内径寸法は、電極保持部１１の基端側１１Ｅの外径寸法と対応して締め輪部３１の内径寸法よりも大きく設定される一方、取付部４２の外径寸法は、締め輪部３１の外径寸法と略同一とされる。載置本体部４３の略中央部にはねじ孔４４が形成されており、載置部４１がベース部２０上に載置されたときには、ねじ孔４４が上記したボルト挿通孔２５と連通して両孔の孔壁に形成された両雌ねじが連続するようになっている。   The inner diameter dimension of the attachment portion 42 is set to be larger than the inner diameter dimension of the fastening ring portion 31 corresponding to the outer diameter dimension of the proximal end side 11E of the electrode holding portion 11, while the outer diameter dimension of the attachment portion 42 is The outer diameter of the ring portion 31 is substantially the same. A screw hole 44 is formed at a substantially central portion of the mounting main body 43. When the mounting portion 41 is mounted on the base portion 20, the screw hole 44 communicates with the bolt insertion hole 25 described above. Both female screws formed in the hole walls of both holes are continuous.

支持部４５は、図９に示すように、締付部３０と載置部４１のそれぞれの後端位置に連結されており、締付部３０と載置部４１との間を電極保持部１１の高さ寸法よりも小さい一定間隔に保持可能となっている。支持部４５は、締付部３０の締め輪部３１及び載置部４１の取付部４２の円弧に沿って湾曲する形態とされ、その内外面が取付部４２の内外面に略面一で連なって略鉛直に起立している。また、支持部４５は、アーム部３２が傾動したときにも、その起立状態を保つことが可能な剛性を有している。   As shown in FIG. 9, the support portion 45 is connected to the respective rear end positions of the tightening portion 30 and the placement portion 41, and the electrode holding portion 11 is interposed between the tightening portion 30 and the placement portion 41. It can be held at a fixed interval smaller than the height dimension. The support portion 45 is configured to bend along the arc of the fastening ring portion 31 of the fastening portion 30 and the attachment portion 42 of the mounting portion 41, and the inner and outer surfaces thereof are substantially flush with the inner and outer surfaces of the attachment portion 42. Standing upright. Moreover, the support part 45 has the rigidity which can maintain the standing state even when the arm part 32 tilts.

次に、実施形態２の作用効果を説明する。まず、図７に示すように、取付部４２に電極保持部１１を嵌め込むとともにねじ孔４４にボルト挿通孔２５を整合させつつ締付ユニット４０をベース部２０上に載せる。続いて、下方からボルト２６の軸部２６Ｂをボルト挿通孔２５からねじ孔４４にかけてねじ込み、ボルト２６をベース部２０及び締付ユニット４０に取り付ける。ボルト２６の頭部２６Ａがベース部２０の下面２０Ａに当接する位置に至ると、図１０に示すように、ボルト２６の軸部２６Ｂの先端部分はアーム部３２のボルト通し孔３４を貫通して上方に突出する。   Next, the effect of Embodiment 2 is demonstrated. First, as shown in FIG. 7, the electrode holding part 11 is fitted into the attachment part 42 and the bolting hole 25 is aligned with the screw hole 44 and the fastening unit 40 is placed on the base part 20. Subsequently, the shaft portion 26 </ b> B of the bolt 26 is screwed from below into the screw hole 44 from the bolt insertion hole 25, and the bolt 26 is attached to the base portion 20 and the tightening unit 40. When the head portion 26A of the bolt 26 reaches a position where it abuts against the lower surface 20A of the base portion 20, the tip portion of the shaft portion 26B of the bolt 26 passes through the bolt through hole 34 of the arm portion 32 as shown in FIG. Projects upward.
