図１〜図５に示す本実施形態に係るバッテリー端子１は、バッテリー５０のバッテリーポスト５１に組み付けられるものである。バッテリー端子１は、バッテリーポスト５１に取り付けられることにより、バッテリー５０と、このバッテリー５０が搭載される車両等の本体側の電線の末端に設けられた金具等とを電気的に接続するための部品である。   The battery terminal 1 according to the present embodiment shown in FIGS. 1 to 5 is assembled to the battery post 51 of the battery 50. The battery terminal 1 is a part for electrically connecting the battery 50 and a metal fitting provided at the end of the electric wire on the main body side of the vehicle or the like on which the battery 50 is mounted by being attached to the battery post 51. It is.

なお、以下の説明では、バッテリーポスト５１の中心軸線Ｘに沿った方向を軸方向という。またここでは、以下の説明を分かり易くするために、便宜的に当該軸方向と直交する２方向のうち一方を長辺方向（第１の幅方向）、他方を短辺方向（第２の幅方向）という。これら軸方向、長辺方向、及び、短辺方向は互いに直交する。   In the following description, a direction along the central axis X of the battery post 51 is referred to as an axial direction. Also, here, in order to make the following explanation easy to understand, for convenience, one of the two directions orthogonal to the axial direction is set to the long side direction (first width direction), and the other is set to the short side direction (second width). Direction). The axial direction, the long side direction, and the short side direction are orthogonal to each other.

ここで、このバッテリー端子１が適用されるバッテリー５０は、例えば、車両等に蓄電装置として搭載されるものである。バッテリー５０は、図３、図４、図５等に示すように、バッテリー液や当該バッテリー５０を構成する種々の部品を収容するバッテリー筐体５２、当該バッテリー筐体５２に設けられた上述のバッテリーポスト５１等を含んで構成される。バッテリー筐体５２は、いずれか１つの面が開放された略矩形箱状の筐体本体と、上記開放された面を閉塞させる蓋部材とを含んで構成され、全体として略直方体形状に形成される。ここでは、バッテリー筐体５２は、長辺方向に沿った方向が長辺、短辺方向に沿った方向が短辺となるがこれに限らない。また、バッテリー筐体５２は、典型的には、筐体本体の鉛直方向上側の面が開放されており、当該鉛直方向上側の面を蓋部材によって閉塞させる。つまり、蓋部材は、典型的には、バッテリー筐体５２の鉛直方向上側の面を構成する。そして、バッテリーポスト５１は、鉛等により構成され、バッテリー筐体５２の蓋部材のポスト立設面５３に立設される。ポスト立設面５３は、バッテリー筐体５２においてバッテリーポスト５１が立設される面である。ここでは、当該ポスト立設面５３は、例えば、バッテリー５０が車両等に搭載された状態で、蓋部材の鉛直方向上側の上面である。バッテリーポスト５１は、略円柱形状であり、中心軸線Ｘがポスト立設面５３と直交するような位置関係で当該ポスト立設面５３上に突出するようにして立設される。より詳細には、本実施形態のバッテリーポスト５１は、ポスト立設面５３の角位置近傍に形成された凹部５４内に立設される。当該凹部５４は、ポスト立設面５３の角位置近傍において略矩形状に陥没した部分である。つまり、バッテリーポスト５１は、バッテリー筐体５２の上面であるポスト立設面５３に形成された凹部５４の底面に立設されている。バッテリーポスト５１は、典型的には、軸方向の先端側に進むにつれて径が小さくなるようテーパが付けられている。つまり、バッテリーポスト５１は、先端の外径が基端の外径より小さいテーパ形状となる。バッテリー端子１は、上記のように構成されるバッテリーポスト５１に締結される。   Here, the battery 50 to which the battery terminal 1 is applied is mounted on a vehicle or the like as a power storage device, for example. As shown in FIGS. 3, 4, 5, and the like, the battery 50 includes a battery housing 52 that houses battery liquid and various components that constitute the battery 50, and the above-described battery provided in the battery housing 52. It includes a post 51 and the like. The battery housing 52 is configured to include a substantially rectangular box-shaped housing body whose one surface is open and a lid member for closing the open surface, and is formed in a substantially rectangular parallelepiped shape as a whole. The Here, the battery casing 52 has a long side in the direction along the long side direction and a short side in the direction along the short side direction, but is not limited thereto. The battery casing 52 typically has an open upper surface in the vertical direction of the casing body, and the upper surface in the vertical direction is closed by a lid member. That is, the lid member typically constitutes the upper surface in the vertical direction of the battery housing 52. The battery post 51 is made of lead or the like and is erected on the post erecting surface 53 of the lid member of the battery housing 52. The post standing surface 53 is a surface on which the battery post 51 is erected in the battery housing 52. Here, the post standing surface 53 is, for example, an upper surface on the upper side in the vertical direction of the lid member in a state where the battery 50 is mounted on a vehicle or the like. The battery post 51 has a substantially cylindrical shape, and is erected so as to protrude on the post erection surface 53 in such a positional relationship that the central axis X is orthogonal to the post erection surface 53. More specifically, the battery post 51 of this embodiment is erected in a recess 54 formed in the vicinity of a corner position of the post erection surface 53. The concave portion 54 is a portion that is depressed into a substantially rectangular shape near the corner position of the post standing surface 53. That is, the battery post 51 is erected on the bottom surface of the recess 54 formed on the post erection surface 53 that is the upper surface of the battery housing 52. The battery post 51 is typically tapered such that its diameter decreases as it advances toward the tip end in the axial direction. That is, the battery post 51 has a tapered shape in which the outer diameter of the tip is smaller than the outer diameter of the base end. The battery terminal 1 is fastened to the battery post 51 configured as described above.

なお、以下の説明では、バッテリー５０が車両等に搭載された状態で、バッテリーポスト５１の軸方向が鉛直方向に沿った方向となり、上述の長辺方向、短辺方向が水平方向に沿った方向となる場合を説明する。   In the following description, in a state where the battery 50 is mounted on a vehicle or the like, the axial direction of the battery post 51 is a direction along the vertical direction, and the long side direction and the short side direction described above are directions along the horizontal direction.

And the battery terminal 1 of this embodiment converts the clamping force by the fastening member generated in the direction along the axial direction into the pressing force in the width direction of the annular portion intersecting with the axial direction, and the battery terminal by the pressing force. 1, the battery post 51 is fastened to the battery post 51 by pressing a portion where the battery post 51 is inserted. At this time, the battery terminal 1 of the present embodiment has a configuration in which the fastening member is fastened from the upper side in the vertical direction, so that the work space of the tool for fastening the fastening member is above the battery 50 and the work on the side of the battery 50 is performed. The space is reduced, thereby improving the workability.

具体的には、本実施形態のバッテリー端子１は、本体部２１と、スタッドボルト２２と、締付部２３とを備える。なお、以下の説明では、特に断りのない限り、バッテリー端子１がバッテリー５０のバッテリーポスト５１に取り付けられ、当該バッテリー５０が車両等に搭載された状態で軸方向、長辺方向、短辺方向となる方向を、それぞれ単に「軸方向」、「長辺方向」、「短辺方向」という。   Specifically, the battery terminal 1 of the present embodiment includes a main body portion 21, a stud bolt 22, and a tightening portion 23.

To do. Further, the stacking direction is typically a direction along the axial direction in a state where the battery terminal 1 is assembled to the battery post 51, and here, a side from which a shaft portion 22a of a stud bolt 22 to be described later protrudes. The upper side in the stacking direction and the opposite side are the lower side in the stacking direction. The upper side in the stacking direction corresponds to the front end side of the battery post 51, and the lower side in the stacking direction corresponds to the base end side of the battery post 51. Here, as for the main-body part 21, the cyclic | annular part 21a and the bolt holding part 21c become a lamination direction upper side, and the cyclic | annular part 21b and the bolt holding part 21d become a lamination direction lower side.

A post insertion hole 21g is formed. Each of the post insertion hole 21f and the post insertion hole 21g has an inner peripheral wall surface formed by folding the sheet metal in the same direction, here, the lower side. The post insertion hole 21f and the post insertion hole 21g have a taper corresponding to the taper of the battery post 51 described above on each inner peripheral wall surface. Here, of the post insertion hole 21f and the post insertion hole 21g, the side from which a shaft portion 22a of a stud bolt 22 to be described later protrudes, that is, the inner diameter of the post insertion hole 21f is minimized, and the opposite side of the post insertion hole 21g side. The maximum inner diameter is obtained. Each of the post insertion holes 21 f and the post insertion holes 21 g comes into contact with the battery posts 51 in a state where the battery posts 51 are inserted.

また、一対の環状部２１ａ、２１ｂは、屈曲連結部２１ｅを介して上下に積層された状態でスリット２１ｈとスリット２１ｉとが積層方向に対向する位置関係となるように当該スリット２１ｈ、スリット２１ｉが形成される。スリット２１ｈ、スリット２１ｉは、屈曲連結部２１ｅにて連続しており、全体として屈曲連結部２１ｅ及び環状部２１ａ、２１ｂにおいて、当該屈曲連結部２１ｅからポスト挿入孔２１ｆ、ポスト挿入孔２１ｇまで延在している。言い換えれば、スリット２１ｈ、２１ｉは、ポスト挿入孔２１ｆ、２１ｇから環状部２１ａ、２１ｂの一部を分断するようにして屈曲連結部２１ｅまで延在して形成される。   In addition, the pair of annular portions 21a and 21b are arranged such that the slit 21h and the slit 21i are in a positional relationship in which the slit 21h and the slit 21i face each other in the stacking direction in a state where the slits 21h and 21i are stacked vertically via the bending connection portion 21e.

The slit 21h and the slit 21i are continuous at the bent connecting portion 21e, and extend as a whole from the bent connecting portion 21e to the post insertion hole 21f and the post insertion hole 21g in the bent connecting portion 21e and the annular portions 21a and 21b. doing. In other words, the slits 21h and 21i are formed to extend from the post insertion holes 21f and 21g to the bent connection portion 21e so as to divide a part of the annular portions 21a and 21b.

さらに、一対の環状部２１ａ、２１ｂは、それぞれポスト挿入孔２１ｆ、２１ｇから屈曲連結部２１ｅまでの間の部分が後述の締付部２３によって締め付けられる締付端部２１ｋ、２１ｌを構成する。スリット２１ｈ、２１ｉは、この締付端部２１ｋ、２１ｌを短辺方向に沿ってポスト挿入孔２１ｆ、２１ｇから屈曲連結部２１ｅまで貫通する。締付端部２１ｋ、２１ｌは、長辺方向一方側の端部に、後述の当接部２４ｂが嵌合する略矩形状の切り欠き部２１ｍ、２１ｎが形成されている。   Further, the pair of annular portions 21a and 21b constitute tightening end portions 21k and 21l in which portions between the post insertion holes 21f and 21g and the bent connection portion 21e are tightened by a tightening portion 23 described later. The slits 21h and 21i penetrate the tightening end portions 21k and 21l from the post insertion holes 21f and 21g to the bent connection portion 21e along the short side direction. The fastening end portions 21k and 21l are formed with substantially rectangular cutout portions 21m and 21n into which a contact portion 24b described later is fitted at one end portion in the long side direction.

一対のボルト保持部２１ｃ、２１ｄは、折り曲げ加工の前に事前に各ボルト挿入孔２１ｊにスタッドボルト２２が挿入された状態で折り曲げ加工されることで、屈曲連結部２１ｅを介して上下に積層された状態で当該スタッドボルト２２を保持する。本体部２１は、各ボルト挿入孔２１ｊにスタッドボルト２２の軸部２２ａが挿入された状態で、ボルト保持部２１ｃから折り返された折返部２１ｏと、ボルト保持部２１ｄとの間にスタッドボルト２２の基部２２ｂ（軸部２２ａが立設される矩形板状の台座部分）を保持する（図５等参照）。   The pair of bolt holding portions 21c and 21d are stacked in the vertical direction via the bending connecting portion 21e by bending in a state in which the stud bolt 22 is inserted into each bolt insertion hole 21j in advance before bending. In this state, the stud bolt 22 is held. The main body portion 21 includes the stud bolt 22 between the folded portion 21o folded from the bolt holding portion 21c and the bolt holding portion 21d in a state where the shaft portion 22a of the stud bolt 22 is inserted into each bolt insertion hole 21j. A base 22b (a rectangular plate-like pedestal portion on which the shaft 22a is erected) is held (see FIG. 5 and the like).

スタッドボルト２２は、ボルト保持部２１ｃとボルト保持部２１ｄとの間に保持された状態で、各ボルト挿入孔２１ｊから軸部２２ａが軸方向に沿って突出するようにして露出している。スタッドボルト２２は、各ボルト挿入孔２１ｊから露出した当該軸部２２ａに電線等の末端に設けられた端子金具等が電気的に接続される。   The stud bolt 22 is exposed so that the shaft portion 22a protrudes along the axial direction from each bolt insertion hole 21j while being held between the bolt holding portion 21c and the bolt holding portion 21d. The stud bolt 22 is electrically connected to a terminal fitting provided at the end of an electric wire or the like to the shaft portion 22a exposed from each bolt insertion hole 21j.

なお、以上の説明では、本体部２１は、導電性を有する金属板のプレス折り曲げ加工等により、一対の環状部２１ａ、２１ｂ、一対のボルト保持部２１ｃ、２１ｄ、及び、屈曲連結部２１ｅが一体で形成されるものとして説明したがこれに限らない。本体部２１は、例えば、屈曲連結部２１ｅを備えず、軸方向に対して上側分割体（環状部２１ａ、ボルト保持部２１ｃ）と下側分割体（環状部２１ｂ、ボルト保持部２１ｄ）との２層分割構造とし、別体に構成される上側分割体と下側分割体とを一体化する構成を有するものであってもよい。   In the above description, the body portion 21 is formed by integrating the pair of annular portions 21a and 21b, the pair of bolt holding portions 21c and 21d, and the bending connecting portion 21e by, for example, press bending of a conductive metal plate. However, the present invention is not limited to this. The main body portion 21 does not include, for example, the bending connection portion 21e, and includes an upper divided body (annular portion 21a and bolt holding portion 21c) and a lower divided body (annular portion 21b and bolt holding portion 21d) with respect to the axial direction. You may have a structure which makes it a 2 layer division structure and integrates the upper division body and lower division body which are comprised separately.

The tightening portion 23 includes an L-shaped bolt 24 as a width direction member, a fastening nut 25 as a fastening member, and a bracket 26 as a pressing force conversion member.

Ｌ字ボルト２４は、金属等によって略Ｌ字型の棒状に形成され、環状部幅方向に沿って環状部２１ａ、２１ｂの一端側からスリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの他端側まで延在して配置される。ここで、環状部幅方向とは、バッテリーポスト５１の中心軸線Ｘに沿った軸方向と交差する方向、ここでは軸方向と直交する方向であって環状部２１ａ、２１ｂに形成されたスリット２１ｈ、２１ｉを横断する方向である。環状部幅方向は、典型的には、環状部２１ａ、２１ｂをバッテリーポスト５１に締結する際に環状部２１ａ、２１ｂを締め付ける方向（締め付け方向）に沿った方向に相当する。本実施形態の環状部幅方向は、バッテリー端子１がバッテリーポスト５１に取り付けられた状態で、長辺方向に沿った方向となっている。   The L-shaped bolt 24 is formed in a substantially L-shaped rod shape by metal or the like, and the other ends of the annular portions 21a and 21b across the slits 21h and 21i from one end side of the annular portions 21a and 21b along the annular portion width direction. It is arranged extending to the side. Here, the annular portion width direction is a direction intersecting with the axial direction along the center axis X of the battery post 51, here, a direction orthogonal to the axial direction and formed in the annular portions 21a and 21b, It is a direction which crosses 21i. The annular portion width direction typically corresponds to a direction along the direction (tightening direction) in which the annular portions 21a and 21b are tightened when the annular portions 21a and 21b are fastened to the battery post 51. The annular portion width direction of the present embodiment is a direction along the long side direction in a state where the battery terminal 1 is attached to the battery post 51.

具体的には、Ｌ字ボルト２４は、軸部２４ａと、当接部２４ｂと、螺合部２４ｃとを有し、これらが一体で形成される。軸部２４ａは、円柱棒状に形成され、環状部幅方向に沿って環状部２１ａ、２１ｂの一端側からスリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの他端側まで貫通する。当接部２４ｂは、軸部２４ａの環状部幅方向の一端側に設けられる。ここでは、当接部２４ｂは、軸部２４ａが環状部幅方向に沿って環状部２１ａ、２１ｂの一端側からスリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの他端側まで貫通するように本体部２１に組み付けられた状態で、切り欠き部２１ｍ、２１ｎ側に位置する端部に、当該軸部２４ａと一体で形成される。当接部２４ｂは、環状部幅方向に対する環状部２１ａ、２１ｂの一端側で環状部２１ａ、２１ｂと当接する部分である。ここでは、当接部２４ｂは、略矩形板状に形成され、Ｌ字ボルト２４が本体部２１に組み付けられた状態で、上述の締付端部２１ｋ、２１ｌの長辺方向一方側の端部に形成された各切り欠き部２１ｍ、２１ｎに嵌合して環状部２１ａ、２１ｂと当接する。螺合部２４ｃは、軸部２４ａの環状部幅方向の他端側に設けられる。ここでは、螺合部２４ｃは、軸部２４ａが環状部幅方向に沿って環状部２１ａ、２１ｂの一端側からスリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの他端側まで貫通するように本体部２１に組み付けられた状態で、切り欠き部２１ｍ、２１ｎ側とは反対側の端部に、当該軸部２４ａと一体で形成される。螺合部２４ｃは、当該軸部２４ａの環状部幅方向の他端側の端部が軸方向に沿って略Ｌ型に屈曲することで形成される。螺合部２４ｃは、後述する締結ナット２５が螺合可能な螺合溝２４ｄが形成されている。   Specifically, the L-shaped bolt 24 includes a shaft portion 24a, a contact portion 24b, and a screwing portion 24c, which are integrally formed. The shaft portion 24a is formed in a cylindrical bar shape, and penetrates from the one end side of the annular portions 21a, 21b to the other end side of the annular portions 21a, 21b across the slits 21h, 21i along the annular portion width direction. The contact portion 24b is provided on one end side in the annular portion width direction of the shaft portion 24a. Here, the contact portion 24b is formed such that the shaft portion 24a penetrates from one end side of the annular portions 21a, 21b to the other end side of the annular portions 21a, 21b across the slits 21h, 21i along the annular portion width direction. In the state assembled to the main body portion 21, it is formed integrally with the shaft portion 24a at the end portion located on the notch portions 21m, 21n side. The contact portion 24b is a portion that contacts the annular portions 21a and 21b on one end side of the annular portions 21a and 21b with respect to the annular portion width direction. Here, the contact portion 24b is formed in a substantially rectangular plate shape, and the end portion on one side in the long side direction of the above-described tightening end portions 21k and 21l in a state where the L-shaped bolt 24 is assembled to the main body portion 21. It fits in each notch part 21m and 21n formed in this, and contact | abuts to the annular parts 21a and 21b. The screw portion 24c is provided on the other end side in the annular portion width direction of the shaft portion 24a. Here, the threaded portion 24c is such that the shaft portion 24a penetrates from one end side of the annular portions 21a, 21b to the other end side of the annular portions 21a, 21b across the slits 21h, 21i along the annular portion width direction. In the state assembled to the main body portion 21, it is formed integrally with the shaft portion 24a at the end opposite to the notches 21m and 21n. The threaded portion 24c is formed by bending the end portion on the other end side in the annular portion width direction of the shaft portion 24a into a substantially L shape along the axial direction. The screwing portion 24c is formed with a screwing groove 24d into which a fastening nut 25 described later can be screwed.

Ｌ字ボルト２４は、図２に二点鎖線で例示するように、螺合部２４ｃを短辺方向に沿って倒した状態（寝かせた状態）で、当該螺合部２４ｃ側を環状部２１ａ、２１ｂの切り欠き部２１ｍ、２１ｎ側から締付端部２１ｋと締付端部２１ｌとの間に挿入し、環状部幅方向に沿って環状部２１ａ、２１ｂの一端側から他端側まで貫通させた後、当該螺合部２４ｃを軸方向に沿うように起立させることで、本体部２１に組み付けられる。つまり、Ｌ字ボルト２４は、環状部幅方向に沿ってスリット２１１ｈ、２１ｉを横断するような位置関係で本体部２１に組み付けられる。Ｌ字ボルト２４は、本体部２１に組み付けられた状態で、当接部２４ｂが切り欠き部２１ｍ、２１ｎに嵌合すると共に螺合部２４ｃが締付端部２１ｋ、２１ｌを挟んで当接部２４ｂとは反対側に位置し、当接部２４ｂと螺合部２４ｃとが環状部幅方向（長辺方向）に対向する。そして、Ｌ字ボルト２４は、本体部２１に組み付けられた状態で、螺合部２４ｃの先端が軸方向一方側、ここでは、ポスト立設面５３とは反対側すなわち、鉛直方向上側を向く。   As illustrated by a two-dot chain line in FIG. 2, the L-shaped bolt 24 is in a state where the screwed portion 24 c is tilted along the short side direction (laid state), and the screwed portion 24 c side is annular portion 21 a, 21b is inserted between the clamping end 21k and the clamping end 21l from the notch 21m, 21n side, and penetrates from one end side to the other end side of the annular portions 21a, 21b along the annular portion width direction. After that, the screwing portion 24c is erected along the axial direction to be assembled to the main body portion 21. That is, the L-shaped bolt 24 is assembled to the main body portion 21 in such a positional relationship as to cross the slits 211h and 21i along the annular portion width direction. When the L-shaped bolt 24 is assembled to the main body 21, the contact portion 24b fits into the notches 21m and 21n, and the screwing portion 24c sandwiches the tightening end portions 21k and 21l. It is located on the opposite side to 24b, and the contact part 24b and the screwing part 24c are opposed to the annular part width direction (long side direction). In the state where the L-shaped bolt 24 is assembled to the main body 21, the tip end of the screwing portion 24 c faces one side in the axial direction, here, the side opposite to the post standing surface 53, that is, the upper side in the vertical direction.

締結ナット２５は、Ｌ字ボルト２４の螺合部２４ｃと螺合するものである。締結ナット２５は、軸方向周りの回転に伴って、螺合部２４ｃとの螺合作用により、軸方向に沿って移動する。   The fastening nut 25 is screwed with the screwing portion 24 c of the L-shaped bolt 24. The fastening nut 25 moves along the axial direction by the screwing action with the screwing portion 24c as the shaft rotates around the axial direction.

ブラケット２６は、締結ナット２５に沿った移動に伴って当該軸方向に沿って移動可能に設けられ、環状部幅方向の押圧力を発生させるものである。ここでは、ブラケット２６は、螺合部２４ｃに組み付けられた状態で締結ナット２５に沿った移動に伴って当該軸方向に沿って移動し、環状部２１ａ、２１ｂの他端側、すなわち、螺合部２４ｃが位置する側で当該環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌと当接し、環状部幅方向の押圧力を発生させる。ブラケット２６は、締結ナット２５の軸方向周りの回転に伴って締結ナット２５とＬ字ボルト２４との間に発生する軸方向の締付力を、環状部幅方向の押圧力に変換する。ここで、環状部幅方向の押圧力とは、ブラケット２６と当接部２４ｂとの間で環状部幅方向に沿って環状部２１ａ、２１ｂのスリット２１ｈ、２１ｉの間隔を縮小する方向に当該環状部２１ａ、２１ｂを押圧する力である。   The bracket 26 is provided so as to be movable along the axial direction along with the movement along the fastening nut 25 and generates a pressing force in the annular portion width direction. Here, the bracket 26 moves along the axial direction along with the movement along the fastening nut 25 in a state where it is assembled to the screwing portion 24c, so that the other end side of the annular portions 21a and 21b, that is, screwing. On the side where the portion 24c is located, it comes into contact with the tightening end portions 21k, 21l of the annular portions 21a, 21b, and generates a pressing force in the annular portion width direction. The bracket 26 converts the axial tightening force generated between the fastening nut 25 and the L-shaped bolt 24 as the fastening nut 25 rotates in the axial direction into a pressing force in the annular portion width direction. Here, the pressing force in the annular portion width direction refers to the annular force in the direction of reducing the interval between the slits 21h and 21i of the annular portions 21a and 21b along the annular portion width direction between the bracket 26 and the contact portion 24b. It is the force which presses the parts 21a and 21b.

具体的には、ブラケット２６は、略矩形板状に形成される基部２６ａと、当該基部２６ａと一体で形成され当該基部２６ａの４辺のうち対向する２辺から鉛直方向下側へ延在する一対の直立部２６ｂとを含んで構成される。一対の直立部２６ｂは、短辺方向に対向する。ブラケット２６は、例えば、金属板のプレス折り曲げ加工等により、基部２６ａ、及び、各直立部２６ｂ全体として略コの字型に形成される。そして、ブラケット２６は、基部２６ａに形成される貫通部２６ｃと、各直立部２６ｂに形成されるテーパ面２６ｄとを有する。   Specifically, the bracket 26 is formed integrally with the base portion 26a formed in a substantially rectangular plate shape, and extends from the two opposite sides of the base portion 26a downward in the vertical direction. It is comprised including a pair of upright part 26b. The pair of upright portions 26b oppose each other in the short side direction. The bracket 26 is formed in a substantially U shape as a whole of the base portion 26a and the upright portions 26b by, for example, press bending of a metal plate. And the bracket 26 has the penetration part 26c formed in the base part 26a, and the taper surface 26d formed in each upright part 26b.

貫通部２６ｃは、螺合部２４ｃが貫通する略正円形状の貫通孔であり、基部２６ａを軸方向に貫通するようにして形成される。ブラケット２６は、当該貫通部２６ｃに軸方向に沿って螺合部２４ｃが挿入されることで、軸方向に沿って移動可能に当該螺合部２４ｃに組み付けられる。ブラケット２６は、貫通部２６ｃに螺合部２４ｃが挿入されるような位置関係で当該螺合部２４ｃに組み付けられた状態で、各直立部２６ｂが基部２６ａより軸部２４ａ側に位置する。典型的には、ブラケット２６は、螺合部２４ｃに組み付けられた状態で、基部２６ａが鉛直方向上側、各直立部２６ｂが鉛直方向下側に位置する。   The through portion 26c is a substantially circular through hole through which the screwing portion 24c passes, and is formed so as to penetrate the base portion 26a in the axial direction. The bracket 26 is assembled to the threaded portion 24c so as to be movable along the axial direction by inserting the threaded portion 24c along the axial direction into the penetrating portion 26c. In the bracket 26, each upright portion 26 b is positioned closer to the shaft portion 24 a than the base portion 26 a in a state where the bracket 26 is assembled to the screw portion 24 c in such a positional relationship that the screw portion 24 c is inserted into the through portion 26 c. Typically, in a state where the bracket 26 is assembled to the screwing portion 24c, the base portion 26a is located on the upper side in the vertical direction, and the upright portions 26b are located on the lower side in the vertical direction.

テーパ面２６ｄは、各直立部２６ｂの長辺方向の一方の端面にそれぞれ形成される。テーパ面２６ｄは、環状部２１ａ、２１ｂの他端側、すなわち、螺合部２４ｃが位置する側で当該環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌと対向する面に形成され当該締付端部２１ｋ、２１ｌと当接する当接面を構成する。そして、各テーパ面２６ｄは、軸方向周りの締結ナット２５の回転に伴って当該締結ナット２５と共に当該ブラケット２６が軸方向に沿って軸部２４ａ側に接近した際に、締結ナット２５と軸部２４ａとの間に発生する軸方向の締付力を、環状部２１ａ、２１ｂを環状部幅方向の当接部２４ｂ側に押圧する環状部幅方向の押圧力に変換する方向に傾斜している。ここでは、各テーパ面２６ｄは、軸方向に対して傾斜している。より詳細には、各テーパ面２６ｄは、ブラケット２６が螺合部２４ｃに組み付けられた状態で、基部２６ａ側から軸方向に沿って離間するのにしたがって徐々に締付端部２１ｋ、２１ｌ側から離間するような傾斜面（言い換えれば、各直立部２６ｂの環状部幅方向に沿った幅が徐々に狭まるような傾斜面）として形成される。   The tapered surface 26d is formed on one end surface in the long side direction of each upright portion 26b. The taper surface 26d is formed on a surface facing the tightening end portions 21k and 21l of the annular portions 21a and 21b on the other end side of the annular portions 21a and 21b, that is, the side where the screwing portion 24c is located. A contact surface that contacts the end portions 21k and 21l is formed. Then, each tapered surface 26d is formed so that the fastening nut 25 and the shaft portion are formed when the bracket 26 together with the fastening nut 25 approaches the shaft portion 24a side along the axial direction along with the rotation of the fastening nut 25 around the axial direction. The axial direction tightening force generated with respect to 24a is inclined in a direction to convert the annular portions 21a and 21b into a pressing force in the annular portion width direction that presses the annular portions 21b toward the contact portion 24b side in the annular portion width direction. . Here, each taper surface 26d is inclined with respect to the axial direction. More specifically, each taper surface 26d is gradually removed from the tightening end portions 21k and 21l as it is separated from the base portion 26a side in the axial direction in a state where the bracket 26 is assembled to the screwing portion 24c. It is formed as an inclined surface that separates (in other words, an inclined surface in which the width along the annular portion width direction of each upright portion 26b gradually decreases).

さらに、本実施形態の環状部２１ａ、２１ｂは、環状部幅方向の他端側のブラケット２６と当接する部位、すなわち、締付端部２１ｋ、２１ｌにおいて螺合部２４ｃが位置する側（螺合部２４ｃと対向する側）の端面にガイド部２１ｐを有する。ガイド部２１ｐは、ブラケット２６の軸方向周りの回転を規制すると共にブラケット２６の軸方向に沿った移動を案内するものである。ガイド部２１ｐは、締付端部２１ｋ、２１ｌそれぞれに、ブラケット２６の各テーパ面２６ｄが挿入される切り欠き部として形成される（図２等参照）。ここでは、各ガイド部２１ｐは、テーパ面２６ｄの傾斜と対応するような形状に形成されている。すなわち、各ガイド部２１ｐは、締付端部２１ｋに各テーパ面２６ｄに対応して一対が設けられ、締付端部２１ｌに各テーパ面２６ｄに対応して一対が設けられる。そして、各ガイド部２１ｐは、締付端部２１ｋ側に形成されるガイド部２１ｐの切り欠き量（環状部幅方向に沿った深さ）が締付端部２１ｌ側に形成されるガイド部２１ｐの切り欠き量より大きくなるように形成される。各ガイド部２１ｐは、各テーパ面２６ｄが挿入されることで、ブラケット２６の軸方向周りの回転を規制しブラケット２６の軸方向に沿った移動を案内することができる。   Further, the annular portions 21a and 21b of the present embodiment are in contact with the bracket 26 on the other end side in the annular portion width direction, that is, on the side where the screwing portion 24c is located at the tightening end portions 21k and 21l (screwing). The guide portion 21p is provided on the end surface on the side facing the portion 24c. The guide portion 21p regulates the rotation of the bracket 26 around the axial direction and guides the movement of the bracket 26 along the axial direction. The guide portion 21p is formed in each of the tightening end portions 21k and 21l as a notch portion into which each tapered surface 26d of the bracket 26 is inserted (see FIG. 2 and the like). Here, each guide portion 21p is formed in a shape corresponding to the inclination of the tapered surface 26d. That is, each guide portion 21p is provided with a pair corresponding to each tapered surface 26d at the tightening end portion 21k, and a pair corresponding to each tapered surface 26d at the tightening end portion 21l. Each guide portion 21p has a guide portion 21p in which the notch amount (depth along the annular portion width direction) of the guide portion 21p formed on the tightening end portion 21k side is formed on the tightening end portion 21l side. It is formed to be larger than the notch amount. Each guide portion 21p can guide the movement of the bracket 26 along the axial direction by restricting the rotation of the bracket 26 around the axial direction by inserting each tapered surface 26d.

上記のように構成されるバッテリー端子１は、Ｌ字ボルト２４が本体部２１に組み付けられた状態で、当接部２４ｂが環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌの環状部幅方向一方側で切り欠き部２１ｍ、２１ｎに嵌合すると共に、螺合部２４ｃが当該締付端部２１ｋ、２１ｌの環状部幅方向他方側に位置し、当該螺合部２４ｃの先端が軸方向一方側（鉛直方向上側）を向いている。そして、バッテリー端子１は、ブラケット２６の貫通部２６ｃに螺合部２４ｃが挿入され、ガイド部２１ｐに各テーパ面２６ｄが位置するような位置関係で、螺合部２４ｃにブラケット２６が組み付けられる。そして、バッテリー端子１は、軸方向に対して、Ｌ字ボルト２４の軸部２４ａと締結ナット２５との間にブラケット２６が介在するような位置関係で螺合部２４ｃに締結ナット２５が組み付けられる。そして、バッテリー端子１は、スタッドボルト２２の軸部２２ａが露出するような位置関係でポスト挿入孔２１ｆ、２１ｇにバッテリーポスト５１が挿入されることで、バッテリーポスト５１に組み付けられる。そして、バッテリー端子１は、ポスト挿入孔２１ｆ、２１ｇの内周面とバッテリーポスト５１の外周面とが接触した状態で、締結ナット２５が軸方向一方側、ここでは、鉛直方向上側から締め付けられることで、スリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌの両側が接近方向に締め付けられ、これにより、バッテリーポスト５１に締結される。   In the battery terminal 1 configured as described above, in the state where the L-shaped bolt 24 is assembled to the main body portion 21, the contact portion 24b has the tightening end portions 21k and 21l of the annular portions 21a and 21b in the width direction of the annular portion. One side engages with the notches 21m and 21n, and the screwing portion 24c is positioned on the other side in the width direction of the annular portion of the tightening end portions 21k and 21l. It faces the side (vertical upper side). The battery terminal 1 is assembled with the bracket 26 in the threaded portion 24c in such a positional relationship that the threaded portion 24c is inserted into the penetrating portion 26c of the bracket 26 and each tapered surface 26d is positioned in the guide portion 21p. In the battery terminal 1, the fastening nut 25 is assembled to the screwing portion 24c in such a positional relationship that the bracket 26 is interposed between the shaft portion 24a of the L-shaped bolt 24 and the fastening nut 25 with respect to the axial direction. . The battery terminal 1 is assembled to the battery post 51 by inserting the battery post 51 into the post insertion holes 21f and 21g in such a positional relationship that the shaft portion 22a of the stud bolt 22 is exposed. The battery terminal 1 is tightened from one side in the axial direction, here the upper side in the vertical direction, with the inner peripheral surfaces of the post insertion holes 21f and 21g and the outer peripheral surface of the battery post 51 in contact with each other. Thus, both sides of the tightening end portions 21k and 21l of the annular portions 21a and 21b are tightened in the approaching direction with the slits 21h and 21i interposed therebetween, thereby being fastened to the battery post 51.

より詳細には、バッテリー端子１は、締結ナット２５が工具等によって軸方向（螺合部２４ｃ）周りに回転されることで、螺合作用により、締結ナット２５が軸方向他方側、ここでは、鉛直方向下側に移動する。バッテリー端子１は、締結ナット２５の軸方向他方側（鉛直方向下側）への移動に伴ってブラケット２６も軸方向他方側へ移動し、Ｌ字ボルト２４の軸部２４ａ側に接近する。このとき、ブラケット２６は、締付端部２１ｋ、２１ｌに形成されたガイド部２１ｐによって軸方向周りの回転が規制されつつ軸方向に沿った移動が案内される。バッテリー端子１は、ブラケット２６の軸方向の移動に伴って当該ブラケット２６に形成された各テーパ面２６ｄが環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌに当接する。バッテリー端子１は、締結ナット２５の回転に伴って当該締結ナット２５と共にブラケット２６が軸方向に沿って軸部２４ａ側に接近すると、各テーパ面２６ｄの作用によって、締結ナット２５と軸部２４ａとの間に発生する軸方向の締付力が、環状部２１ａ、２１ｂを環状部幅方向の当接部２４ｂ側に押圧する環状部幅方向の押圧力、言い換えれば、スリット２１ｈ、２１ｉの間隔を縮小する方向への押圧力に変換される（図５中の矢印Ａ参照）。これにより、バッテリー端子１は、各テーパ面２６ｄからの環状部幅方向の押圧力によって環状部２１ａ、２１ｂが環状部幅方向の当接部２４ｂ側に押圧される。このとき、当接部２４ｂは、各テーパ面２６ｄによる押圧力の反力を受ける反力部材として機能する。この結果、バッテリー端子１は、各テーパ面２６ｄによる押圧力によって、環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌがスリット２１ｈ、２１ｉの間隔を縮小する方向に押圧され、当該スリット２１ｈ、２１ｉの間隔が狭まる。   More specifically, in the battery terminal 1, the fastening nut 25 is rotated around the axial direction (screwing portion 24c) by a tool or the like, so that the fastening nut 25 is moved to the other side in the axial direction by the screwing action. Move vertically down. In the battery terminal 1, the bracket 26 also moves to the other side in the axial direction along with the movement of the fastening nut 25 toward the other side in the axial direction (downward in the vertical direction), and approaches the shaft part 24 a side of the L-shaped bolt 24. At this time, the bracket 26 is guided to move along the axial direction while the rotation around the axial direction is restricted by the guide portion 21p formed at the tightening end portions 21k and 21l. In the battery terminal 1, as the bracket 26 moves in the axial direction, each tapered surface 26d formed on the bracket 26 comes into contact with the tightening end portions 21k and 21l of the annular portions 21a and 21b. When the bracket 26 approaches the shaft portion 24a along the axial direction along with the rotation of the fastening nut 25 along with the rotation of the fastening nut 25, the battery terminal 1 is connected to the fastening nut 25 and the shaft portion 24a by the action of each tapered surface 26d. The axial tightening force generated between the annular portions 21a and 21b presses the annular portions in the width direction of the annular portions 21a and 21b, in other words, the interval between the slits 21h and 21i. It is converted into a pressing force in the direction of reduction (see arrow A in FIG. 5). Thereby, the battery terminal 1 is pressed by the annular portions 21a, 21b toward the contact portion 24b in the annular portion width direction by the pressing force in the annular portion width direction from each tapered surface 26d. At this time, the contact portion 24b functions as a reaction force member that receives the reaction force of the pressing force by each tapered surface 26d. As a result, the battery terminal 1 is pressed in the direction in which the tightening end portions 21k and 21l of the annular portions 21a and 21b reduce the interval between the slits 21h and 21i by the pressing force of each tapered surface 26d, and the slits 21h and 21i. The interval of becomes narrower.

したがって、バッテリー端子１は、締結ナット２５の回転に伴ってテーパ面２６ｄが変換、発生させる押圧力によって、スリット２１ｈ、２１ｉの間隔が狭められることで、ポスト挿入孔２１ｆ、２１ｇの内周面とバッテリーポスト５１の外周面とが接触した状態でポスト挿入孔２１ｆ、２１ｇの径が縮小され、バッテリーポスト５１に締結される。そして、バッテリー端子１は、スタッドボルト２２の軸部２２ａに電線の末端に設けられた金具等が電気的に接続される。一方、バッテリー端子１は、締結ナット２５が逆回転に回転されることで、各テーパ面２６ｄによる押圧力が弱まり、スリット２１ｈ、２１ｉの間隔が広がり、ポスト挿入孔２１ｆ、２１ｇの径が拡大され、バッテリーポスト５１から取り外し可能な状態となる。   Accordingly, the battery terminal 1 is formed so that the gap between the slits 21h and 21i is narrowed by the pressing force generated by the conversion and generation of the tapered surface 26d with the rotation of the fastening nut 25, so that the inner peripheral surface of the post insertion holes 21f and 21g The diameters of the post insertion holes 21 f and 21 g are reduced in a state where the outer peripheral surface of the battery post 51 is in contact with the battery post 51 and fastened to the battery post 51. The battery terminal 1 is electrically connected to a shaft portion 22a of the stud bolt 22 with a metal fitting provided at the end of the electric wire. On the other hand, in the battery terminal 1, when the fastening nut 25 is rotated in the reverse direction, the pressing force by each tapered surface 26d is weakened, the interval between the slits 21h and 21i is widened, and the diameters of the post insertion holes 21f and 21g are enlarged. The battery post 51 can be removed.

以上で説明したバッテリー端子１によれば、バッテリーポスト５１が挿入されるポスト挿入孔２１ｆ、２１ｇ、及び、当該ポスト挿入孔２１ｆ、２１ｇと連続するスリット２１ｈ、２１ｉが形成された環状部２１ａ、２１ｂと、バッテリーポスト５１の中心軸線Ｘに沿った軸方向と交差する方向であってスリット２１ｈ、２１ｉを横断する方向である環状部幅方向に沿って環状部２１ａ、２１ｂの一端側からスリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの他端側まで延在して配置されると共に、環状部幅方向の一端側に環状部２１ａ、２１ｂと当接する当接部２４ｂが設けられ、環状部幅方向の他端側に軸方向に沿って屈曲し螺合溝２４ｄが形成された螺合部２４ｃが設けられるＬ字ボルト２４と、螺合部２４ｃと螺合し軸方向周りの回転に伴って軸方向に沿って移動する締結ナット２５と、締結ナット２５の軸方向に沿った移動に伴って当該軸方向に沿って移動可能に設けられ、環状部２１ａ、２１ｂの他端側で当該環状部２１ａ、２１ｂと当接し、締結ナット２５の軸方向周りの回転に伴って締結ナット２５と幅方向部材との間に発生する軸方向の締付力を、当接部２４ｂとの間で環状部幅方向に沿って環状部２１ａ、２１ｂのスリット２１ｈ、２１ｉの間隔を縮小する方向に当該環状部２１ａ、２１ｂを押圧する環状部幅方向の押圧力に変換するブラケット２６とを備える。   According to the battery terminal 1 described above, the annular portions 21a and 21b in which the post insertion holes 21f and 21g into which the battery post 51 is inserted and the slits 21h and 21i continuous with the post insertion holes 21f and 21g are formed. A slit 21h from one end side of the annular portions 21a, 21b along the annular width direction, which is a direction intersecting the axial direction along the central axis X of the battery post 51 and intersecting the slits 21h, 21i. The annular portion 21a, 21b is disposed so as to extend to the other end side of the annular portion 21a, and an abutting portion 24b that contacts the annular portions 21a, 21b is provided on one end side in the annular portion width direction. An L-shaped bolt 24 provided with a threaded portion 24c that is bent along the axial direction on the other end side in the direction and formed with a threaded groove 24d; And the other end of the annular portions 21a and 21b provided to be movable along the axial direction of the fastening nut 25 along with the movement of the fastening nut 25 along the axial direction. The axial tightening force generated between the fastening nut 25 and the width direction member as the fastening nut 25 rotates around the axial direction is brought into contact with the annular portions 21a and 21b on the side, and the contacting portion 24b. A bracket 26 for converting the pressing force in the annular portion width direction to press the annular portions 21a and 21b in the direction of reducing the interval between the slits 21h and 21i of the annular portions 21a and 21b along the annular portion width direction. Prepare.

したがって、バッテリー端子１は、ブラケット２６の作用によって、締結ナット２５の軸方向周りの回転に伴って発生する軸方向の締付力を、Ｌ字ボルト２４に設けられた当接部２４ｂとブラケット２６との間で環状部２１ａ、２１ｂのスリットの間隔を縮小させる環状部幅方向の押圧力に変換することで、環状部２１ａ、２１ｂをバッテリーポスト５１に締結することができる。つまり、バッテリー端子１は、例えば、バッテリーポスト５１の側方、すなわちバッテリー５０の側方に、締結ナット２５を回転させるための工具をセットして回転操作するための作業スペースを確保しなくても、比較的作業スペースを取りやすいバッテリーポスト５１の軸方向一方側（例えば、鉛直方向上方側）から当該工具をセットし操作することができる。この結果、バッテリー端子１は、例えば、バッテリー５０周囲に作業スペースを確保しにくいような場合であっても、バッテリーポスト５１に締結する際の作業性を向上することができる。   Therefore, the battery terminal 1 causes the bracket 26 to apply the axial tightening force generated by the rotation of the fastening nut 25 around the axial direction by the action of the bracket 26 and the bracket 26. The annular portions 21a, 21b can be fastened to the battery post 51 by converting the pressure between the slits of the annular portions 21a, 21b to a pressing force in the annular portion width direction. That is, for example, the battery terminal 1 does not have to secure a work space for rotating by setting a tool for rotating the fastening nut 25 on the side of the battery post 51, that is, on the side of the battery 50. The tool can be set and operated from one side (for example, the upper side in the vertical direction) of the battery post 51, which is relatively easy to take up a work space. As a result, the battery terminal 1 can improve workability when fastened to the battery post 51 even when it is difficult to secure a work space around the battery 50, for example.

より詳細には、以上で説明したバッテリー端子１によれば、Ｌ字ボルト２４は、環状部幅方向に沿って環状部２１ａ、２１ｂの一端側からスリット２１ｈ、２１ｉを挟んで環状部２１ａ、２１ｂの他端側まで貫通し環状部幅方向の一端側に当接部２４ｂが設けられ環状部幅方向の他端側に螺合部２４ｃが設けられる軸部２４ａを有し、ブラケット２６は、軸方向に沿って螺合部２４ｃが挿入される貫通部２６ｃと、環状部２１ａ、２１ｂの他端側で当該環状部２１ａ、２１ｂと当接し軸方向周りの締結ナット２５の回転に伴って当該締結ナット２５と共に当該ブラケット２６が軸方向に沿って軸部２４ａ側に接近した際に、締結ナット２５と軸部２４ａとの間に発生する軸方向の締付力を、環状部２１ａ、２１ｂを環状部幅方向の当接部２４ｂ側に押圧する環状部幅方向の押圧力に変換する方向に傾斜したテーパ面２６ｄとを有する。したがって、バッテリー端子１は、締結ナット２５の軸方向周りの回転に伴って締結ナット２５とＬ字ボルト２４との間に発生する軸方向の締付力を、当接部２４ｂとブラケット２６との間で環状部幅方向に沿ってスリット２１ｈ、２１ｉの間隔を縮小する方向に当該環状部２１ａ、２１ｂを押圧する環状部幅方向の押圧力に変換する構成を実現することができる。   More specifically, according to the battery terminal 1 described above, the L-shaped bolt 24 is formed in the annular portions 21a and 21b with the slits 21h and 21i sandwiched from one end side of the annular portions 21a and 21b along the annular portion width direction. The shaft 26a has a shaft portion 24a which penetrates to the other end side of the ring portion and is provided with a contact portion 24b on one end side in the annular portion width direction and a screwing portion 24c on the other end side in the annular portion width direction. The through portion 26c into which the threaded portion 24c is inserted along the direction, and the fastening with the rotation of the fastening nut 25 around the axial direction in contact with the annular portions 21a and 21b on the other end side of the annular portions 21a and 21b When the bracket 26 together with the nut 25 approaches the shaft portion 24a side along the axial direction, the annular portion 21a, 21b is annularly formed by the axial tightening force generated between the fastening nut 25 and the shaft portion 24a. Contact portion 24 in the width direction And a tapered surface 26d inclined in a direction to convert the pressing force of the annular portion width direction of pressing to the side. Therefore, the battery terminal 1 uses the axial tightening force generated between the fastening nut 25 and the L-shaped bolt 24 as the fastening nut 25 rotates in the axial direction between the contact portion 24 b and the bracket 26. It is possible to realize a configuration in which the pressure is converted into a pressing force in the annular portion width direction that presses the annular portions 21a and 21b in a direction in which the interval between the slits 21h and 21i is reduced along the annular portion width direction.

さらに、以上で説明したバッテリー端子１によれば、環状部２１ａ、２１ｂは、環状部幅方向の他端側のブラケット２６と当接する部位に形成され、ブラケット２６の軸方向周りの回転を規制すると共にブラケット２６の軸方向に沿った移動を案内するガイド部２１ｐを有する。したがって、バッテリー端子１は、締結ナット２５の軸方向に沿った移動に伴ってブラケット２６が軸方向に沿って移動する際に、締付端部２１ｋ、２１ｌに形成されたガイド部２１ｐによって、ブラケット２６の回転を規制しつつ当該ブラケット２６の軸方向に沿った移動を案内する。この結果、バッテリー端子１は、ブラケット２６の位置を適正に保持することができるので、安定した締め付け位置を確保することができることから、この点でもバッテリーポスト５１に締結する際の作業性を向上することができる。またこの場合、バッテリー端子１は、ガイド部２１ｐが環状部２１ａ、２１ｂの締付端部２１ｋ、２１ｌに一体的にガイド部２１ｐを組み込むことができるので、例えば、バッテリー端子１を構成する部品点数を抑制することができ、製造コストを抑制することができる。   Further, according to the battery terminal 1 described above, the annular portions 21a and 21b are formed in a portion that contacts the bracket 26 on the other end side in the annular portion width direction, and restricts the rotation of the bracket 26 around the axial direction. In addition, a guide portion 21p for guiding the movement of the bracket 26 along the axial direction is provided. Therefore, when the bracket 26 moves along the axial direction in accordance with the movement of the fastening nut 25 along the axial direction, the battery terminal 1 is moved by the guide portion 21p formed at the fastening end portions 21k and 21l. The movement of the bracket 26 along the axial direction is guided while the rotation of the bracket 26 is restricted. As a result, since the battery terminal 1 can appropriately hold the position of the bracket 26, a stable tightening position can be ensured, so that the workability at the time of fastening to the battery post 51 is also improved in this respect. be able to. In this case, the battery terminal 1 has the guide portion 21p that can be integrated into the fastening ends 21k and 21l of the annular portions 21a and 21b, so that, for example, the number of parts constituting the battery terminal 1 can be reduced. Can be suppressed, and the manufacturing cost can be suppressed.
