　本発明者は、蓋に対してハンドルが回動可能に取り付けられた鉛蓄電池を車両に搭載したところ、車両の振動に伴い鉛蓄電池の方から異音が発生することを発見した。そこで、この異音の原因を調べたところ、車両の振動に伴いハンドルが蓋に対して回動し、これによりハンドルが蓋に衝突して異音が発生することを突き止めた。 The present inventor has discovered that when a lead-acid battery having a handle rotatably attached to a lid is mounted on a vehicle, an abnormal noise is generated from the lead-acid battery due to the vibration of the vehicle. Therefore, when the cause of this abnormal noise was investigated, it was found that the steering wheel rotated with respect to the lid due to the vibration of the vehicle, which caused the steering wheel to collide with the lid and generate an abnormal noise.
　そこで、本発明の一側面は、車両の振動に伴う鉛蓄電池からの異音の発生を抑制することができる鉛蓄電池の蓋及び鉛蓄電池を提供することを課題とする。 Therefore, one aspect of the present invention is to provide a lead-acid battery lid and a lead-acid battery capable of suppressing the generation of abnormal noise from the lead-acid battery due to vehicle vibration.
　本発明の一側面に係る鉛蓄電池の蓋は、鉛蓄電池の電槽の上部に取り付けられる蓋本体と、蓋本体に対して回動可能に取り付けられるハンドルと、蓋本体に対してハンドルを所定の回動位置に維持するロック機構と、を備える。 The lid of the lead-acid battery according to one aspect of the present invention has a lid body attached to the upper part of the battery case of the lead-acid battery, a handle rotatably attached to the lid body, and a handle to the lid body. It is provided with a lock mechanism that maintains the rotating position.
　この鉛蓄電池の蓋では、ハンドルが蓋本体に対して回動可能に取り付けられているが、ロック機構により、ハンドルを蓋本体に対して所定の回動位置に維持することができる。このため、例えば、鉛蓄電池を車両に搭載した際に、ロック機構により、ハンドルを蓋本体に対して所定の回動位置に維持しておくことで、車両が振動しても、ハンドルが蓋本体に衝突することによる振動の発生を抑制することができる。 In the lid of this lead-acid battery, the handle is rotatably attached to the lid body, but the lock mechanism can maintain the handle in a predetermined rotating position with respect to the lid body. Therefore, for example, when the lead-acid battery is mounted on the vehicle, the handle is maintained at a predetermined rotation position with respect to the lid body by the lock mechanism, so that the handle can be kept on the lid body even if the vehicle vibrates. It is possible to suppress the generation of vibration due to collision with the lid.
　蓋本体は、ハンドルが収容される収容凹部を有し、ロック機構は、ハンドルを、ハンドルが収容凹部に収容された回動位置に維持してもよい。この鉛蓄電池の蓋では、ロック機構により、ハンドルを蓋本体の収容凹部に収容した状態に維持することができるため、ハンドルに邪魔されることなく鉛蓄電池を車両に搭載することができる。 The lid body has an accommodating recess in which the handle is housed, and the locking mechanism may maintain the handle in a rotating position where the handle is housed in the accommodating recess. In the lid of the lead-acid battery, the handle can be maintained in a state of being housed in the housing recess of the lid body by the lock mechanism, so that the lead-acid battery can be mounted on the vehicle without being disturbed by the handle.
　ロック機構は、蓋本体に設けられて蓋本体に対してハンドルを回動可能に軸支するための軸部と、ハンドルに設けられて軸部が嵌め込まれる穴部と、を有し、穴部は、穴部に嵌め込まれた軸部が摺動可能な長穴であってもよい。この鉛蓄電池の蓋では、蓋本体に設けられた軸部がハンドルに設けられた穴部に嵌め込まれることで、蓋本体に対してハンドルを回動可能とすることができる。そして、この穴部が、穴部に嵌め込まれた軸部が摺動可能な長穴であるため、穴部に対する軸部の位置を変えることで、軸部を中心としたハンドルの回動半径を変えることができる。このため、例えば、軸部を中心としたハンドルの回動半径の違いにより、ハンドルの回動軌跡と蓋本体との重なり具合が変わるように、軸部の位置、穴部の位置、及び穴部の長さを設定する。これにより、穴部に対する軸部の位置を変えることで、蓋本体に対してハンドルが回動可能となる状態と、蓋本体に対してハンドルが所定の回動位置に維持される状態とを、切り換えることができる。 The lock mechanism has a shaft portion provided on the lid body for rotatably supporting the handle with respect to the lid body, and a hole portion provided on the handle into which the shaft portion is fitted. May be an elongated hole in which the shaft portion fitted in the hole portion is slidable. In the lid of this lead-acid battery, the handle can be made rotatable with respect to the lid body by fitting the shaft portion provided in the lid body into the hole portion provided in the handle. Since this hole is an elongated hole in which the shaft fitted in the hole is slidable, the radius of rotation of the handle around the shaft can be changed by changing the position of the shaft with respect to the hole. Can be changed. Therefore, for example, the position of the shaft portion, the position of the hole portion, and the hole portion so that the degree of overlap between the rotation locus of the handle and the lid body changes depending on the difference in the turning radius of the handle around the shaft portion. Set the length of. As a result, by changing the position of the shaft portion with respect to the hole portion, the state in which the handle can be rotated with respect to the lid body and the state in which the handle is maintained at a predetermined rotation position with respect to the lid body can be obtained. It can be switched.
　ハンドルは、基端側に穴部が形成されるとともに軸部が穴部に嵌め込まれることにより蓋本体に回動可能に取り付けられるアーム部を有し、穴部は、第一位置と、第一位置よりもアーム部の先端側に位置する第二位置と、を有し、アーム部は、軸部が穴部の第一位置に位置する際に、蓋本体に対して回動可能な形状であり、軸部が穴部の第二位置に位置する際に、蓋本体に対して回動不能な形状であってもよい。この鉛蓄電池の蓋では、軸部を穴部の第一位置に位置することで、蓋本体に対してアーム部が回動可能となり、軸部が穴部の第二位置に位置することで、蓋本体に対してアーム部が回動不能となる。これにより、蓋本体に対してハンドルを回動可能としつつ、ロック機構により、蓋本体に対してハンドルを所定の回動位置に維持することができる。 The handle has an arm portion that is rotatably attached to the lid body by forming a hole portion on the base end side and fitting the shaft portion into the hole portion, and the hole portion is the first position and the first position. It has a second position located closer to the tip of the arm than the position, and the arm has a shape that allows it to rotate with respect to the lid body when the shaft is located at the first position of the hole. There may be a shape that cannot rotate with respect to the lid body when the shaft portion is located at the second position of the hole portion. In the lid of this lead-acid battery, the arm portion can be rotated with respect to the lid body by locating the shaft portion at the first position of the hole portion, and the shaft portion is located at the second position of the hole portion. The arm portion cannot rotate with respect to the lid body. As a result, the handle can be rotated with respect to the lid body, and the handle can be maintained at a predetermined rotation position with respect to the lid body by the lock mechanism.
　ハンドルは、基端側に穴部が形成されるとともに軸部が穴部に嵌め込まれることにより蓋本体に回動可能に取り付けられるアーム部を有し、アーム部は、ハンドルが収容凹部に収容された際に収容凹部の底面に面する第一平面を有し、穴部は、第一位置と、第一位置よりもアーム部の先端側に位置する第二位置と、を有し、第一平面のアーム部の基端側の先端は、軸部が穴部の第一位置に位置する際に、収容凹部の底面に垂直で軸部の中心を通る基準線上、又は、基準線よりもアーム部の先端側に位置し、軸部が穴部の第二位置に位置する際に、基準線よりもアーム部の基端側に位置してもよい。この鉛蓄電池の蓋では、軸部が穴部の第一位置に位置する際は、アーム部の第一平面が収容凹部の底面に押し当てられることなく、蓋本体に対してハンドルを回動することができる。一方、軸部が穴部の第二位置に位置する際は、蓋本体に対してハンドルを回動しようとしても、アーム部の第一平面が収容凹部の底面に押し当てられることで、蓋本体に対するハンドルの回動が阻止される。これにより、蓋本体に対してハンドルを回動可能としつつ、ロック機構により、蓋本体に対してハンドルを所定の回動位置に維持することができる。 The handle has an arm portion that is rotatably attached to the lid body by forming a hole portion on the base end side and fitting the shaft portion into the hole portion, and the arm portion is accommodated in the accommodating recess. It has a first plane facing the bottom surface of the accommodating recess, and the hole has a first position and a second position located closer to the tip of the arm than the first position. The tip of the flat arm portion on the base end side is on the reference line passing through the center of the shaft portion perpendicular to the bottom surface of the accommodating recess when the shaft portion is located at the first position of the hole portion, or the arm is closer to the reference line. When it is located on the tip end side of the portion and the shaft portion is located at the second position of the hole portion, it may be located on the base end side of the arm portion with respect to the reference line. In the lid of this lead-acid battery, when the shaft portion is located at the first position of the hole portion, the handle is rotated with respect to the lid body without the first plane of the arm portion being pressed against the bottom surface of the accommodating recess. be able to. On the other hand, when the shaft portion is located at the second position of the hole portion, even if the handle is to be rotated with respect to the lid main body, the first flat surface of the arm portion is pressed against the bottom surface of the accommodating recess, so that the lid main body The rotation of the handle with respect to is prevented. As a result, the handle can be rotated with respect to the lid body, and the handle can be maintained at a predetermined rotation position with respect to the lid body by the lock mechanism.
　アーム部は、第一平面から延びる円弧面を有し、円弧面の中心は、軸部が穴部の第一位置に位置する際の軸部の中心であり、円弧面の半径は、軸部が穴部の第一位置に位置する際の軸部の中心から収容凹部の底面までの距離以下であってもよい。この鉛蓄電池の蓋では、軸部が穴部の第一位置に位置する際に、アーム部の円弧面が収容凹部の底面に押し当てられないため、蓋本体に対してハンドルを回動することができる。 The arm portion has an arc plane extending from the first plane, the center of the arc plane is the center of the shaft portion when the shaft portion is located at the first position of the hole portion, and the radius of the arc plane is the shaft portion. May be less than or equal to the distance from the center of the shaft portion to the bottom surface of the accommodating recess when is located at the first position of the hole portion. In the lid of this lead-acid battery, when the shaft portion is located at the first position of the hole portion, the arc surface of the arm portion is not pressed against the bottom surface of the accommodating recess, so that the handle must be rotated with respect to the lid body. Can be done.
　アーム部は、円弧面から延びるとともにハンドルが蓋本体に対して垂直に直立した際に収容凹部の底面に面する第二平面を有してもよい。この鉛蓄電池の蓋では、蓋本体に対してハンドルを持ち上げると、アーム部の第二平面が収容凹部の底面に当接されることで、ハンドルが蓋本体に対して立ち上げられた状態で保持される。これにより、ハンドルを持ちやすくなる。 The arm portion may have a second plane that extends from the arcuate surface and faces the bottom surface of the accommodating recess when the handle stands upright with respect to the lid body. With the lid of this lead-acid battery, when the handle is lifted with respect to the lid body, the second plane of the arm portion is brought into contact with the bottom surface of the accommodating recess, so that the handle is held in a raised state with respect to the lid body. Will be done. This makes it easier to hold the handle.
　本発明の一側面に係る鉛蓄電池は、上記の何れかの鉛蓄電池の蓋を備える。この鉛蓄電池では、上記の蓋を備えるため、車両が振動しても、ハンドルが蓋本体に衝突することによる振動の発生を抑制することができる。 The lead-acid battery according to one aspect of the present invention includes the lid of any of the above-mentioned lead-acid batteries. Since this lead-acid battery is provided with the lid as described above, even if the vehicle vibrates, it is possible to suppress the occurrence of vibration due to the handle colliding with the lid body.

　側面２１Ｃ，２１Ｃは、アーム部２１，２１の対向方向内側に面して、アーム部２１，２１の軸線方向に延びる平面状の面である。第一平面２１Ｄ，２１Ｄは、側面２１Ｃ，２１Ｃと隣接して、アーム部２１，２１の軸線方向に延びる平面状の面である。第一平面２１Ｄ，２１Ｄは、ハンドル２０が収容凹部１４に収容された際に、収容凹部１４の底面１４Ａに面する（図１１及び図１３参照）。円弧面２１Ｅは、第一平面２１Ｄ，２１Ｄの基端２１Ａ，２１Ａ側に隣接して、第一平面２１Ｄ，２１Ｄから延びる円弧状の面である。第二平面２１Ｆ，２１Ｆは、側面２１Ｃ，２１Ｃ及び円弧面２１Ｅの基端２１Ａ，２１Ａ側に隣接して、円弧面２１Ｅから延びる平面状の面である。第二平面２１Ｆ，２１Ｆは、アーム部２１，２１の基端２１Ａ，２１Ａを成す。第二平面２１Ｆ，２１Ｆは、ハンドル２０が蓋本体１０に対して垂直に直立した際に、収容凹部１４の底面１４Ａに面する（図１３参照）。第三平面２１Ｇは、第一平面２１Ｄ，２１Ｄの反対側において側面２１Ｃ，２１Ｃと隣接し、アーム部２１，２１の軸線方向に延びる平面状の面である。第三平面２１Ｇは、ハンドル２０が収容凹部１４に収容された際に、蓋本体１０の天面１１Ａと略面一となる。 The side surfaces 21C and 21C are planar surfaces that face inward in the facing direction of the arm portions 21 and 21 and extend in the axial direction of the arm portions 21 and 21. The first planes 21D and 21D are flat planes extending in the axial direction of the arm portions 21 and 21 adjacent to the side surfaces 21C and 21C. The first planes 21D and 21D face the bottom surface 14A of the accommodating recess 14 when the handle 20 is accommodated in the accommodating recess 14 (see FIGS. 11 and 13). The arcuate surface 21E is an arcuate surface extending from the first planes 21D and 21D adjacent to the base ends 21A and 21A of the first planes 21D and 21D. The second planes 21F and 21F are flat surfaces extending from the arcuate surface 21E adjacent to the base ends 21A and 21A of the side surfaces 21C and 21C and the arcuate surface 21E. The second planes 21F and 21F form the base ends 21A and 21A of the arm portions 21 and 21. The second planes 21F and 21F face the bottom surface 14A of the accommodating recess 14 when the handle 20 stands upright with respect to the lid body 10 (see FIG. 13). The third plane 21G is a plane surface adjacent to the side surfaces 21C and 21C on the opposite side of the first planes 21D and 21D and extending in the axial direction of the arm portions 21 and 21. The third plane 21G is substantially flush with the top surface 11A of the lid body 10 when the handle 20 is housed in the storage recess 14.
　アーム部２１，２１の基端２１Ａ，２１Ａ側の端部には、蓋本体１０の軸部１６，１６が嵌め込まれる穴部２４，２４が形成されている。穴部２４，２４は、アーム部２１，２１の側面２１Ｃ，２１Ｃに形成された穴であり、Ｘ軸方向に沿って、側面２１Ｃ，２１Ｃから、互いに反対方向に延びるように膨出部２３，２３に向けて延びている。穴部２４，２４は、Ｘ軸方向から見て、互いに同じ位置に形成されている。 Holes 24, 24 into which the shaft portions 16, 16 of the lid main body 10 are fitted are formed at the base ends 21A, 21A side ends of the arm portions 21, 21. The holes 24 and 24 are holes formed in the side surfaces 21C and 21C of the arm portions 21 and 21, and the bulging portions 23 and so as to extend in opposite directions from the side surfaces 21C and 21C along the X-axis direction. It extends toward 23. The holes 24, 24 are formed at the same positions as each other when viewed from the X-axis direction.
　アーム部２１，２１は、軸部１６，１６が穴部２４，２４に嵌め込まれることにより、蓋本体１０に回動可能に取り付けられる。後述するように、軸部１６，１６と穴部２４，２４とは、蓋本体１０に対してハンドル２０を所定の回動位置に維持するロック機構を構成する。本実施形態では、ロック機構は、ハンドル２０を、ハンドル２０が収容凹部１４に収容された回動位置に維持する。 The arm portions 21 and 21 are rotatably attached to the lid body 10 by fitting the shaft portions 16 and 16 into the holes 24 and 24. As will be described later, the shaft portions 16 and 16 and the hole portions 24 and 24 form a locking mechanism for maintaining the handle 20 at a predetermined rotational position with respect to the lid main body 10. In the present embodiment, the locking mechanism maintains the handle 20 in a rotational position where the handle 20 is housed in the housing recess 14.
　また、アーム部２１，２１には、穴部２４，２４の側面２１Ｃ，２１Ｃ側の一部を第一平面２１Ｄ，２１Ｄ側に開放する切欠き２５，２５が形成されている。このため、第一平面２１Ｄ，２１Ｄ側から見た場合に、切欠き２５，２５が形成された部分において、穴部２４，２４が浅くなっている。このため、穴部２４，２４に軸部１６，１６を嵌め込む際は、軸部１６，１６に形成された傾斜面１６Ａ，１６Ａを、アーム部２１，２１に形成された切欠き２５，２５に当接させ、ハンドル２０を収容凹部１４の底面１４Ａ側に押し込む。これにより、穴部２４，２４に軸部１６，１６を容易に嵌め込むことができる。 Further, the arm portions 21 and 21 are formed with notches 25 and 25 that open a part of the side surfaces 21C and 21C of the holes 24 and 24 to the first planes 21D and 21D. Therefore, when viewed from the first planes 21D and 21D, the holes 24 and 24 are shallow in the portions where the notches 25 and 25 are formed. Therefore, when the shaft portions 16 and 16 are fitted into the hole portions 24 and 24, the inclined surfaces 16A and 16A formed in the shaft portions 16 and 16 are formed in the arm portions 21 and 21 with the notches 25 and 25. The handle 20 is pushed into the bottom surface 14A side of the accommodating recess 14. As a result, the shaft portions 16 and 16 can be easily fitted into the hole portions 24 and 24.
　穴部２４，２４は、穴部２４，２４に嵌め込まれた軸部１６，１６が摺動可能な長穴である。本実施形態では、穴部２４，２４は、アーム部２１，２１の軸線方向に延びている。穴部２４，２４は、第一位置２４Ａ，２４Ａと、第一位置２４Ａ，２４Ａよりもアーム部２１，２１の先端２１Ｂ，２１Ｂ側に位置する第二位置２４Ｂ，２４Ｂと、を有する。第一位置２４Ａ，２４Ａ及び第二位置２４Ｂ，２４Ｂは、軸部１６，１６が位置し得る穴位置である。第一位置２４Ａ，２４Ａは、例えば、長穴である穴部２４，２４の基端２１Ａ，２１Ａ側の端部の穴位置であり、第二位置２４Ｂ，２４Ｂは、例えば、長穴である穴部２４，２４の先端２１Ｂ，２１Ｂ側の端部の穴位置である。 The hole portions 24, 24 are elongated holes into which the shaft portions 16, 16 fitted in the hole portions 24, 24 can slide. In the present embodiment, the holes 24 and 24 extend in the axial direction of the arm portions 21 and 21. The holes 24 and 24 have first positions 24A and 24A and second positions 24B and 24B located closer to the tips 21B and 21B of the arm portions 21 and 21 than the first positions 24A and 24A. The first positions 24A and 24A and the second positions 24B and 24B are hole positions where the shaft portions 16 and 16 can be located. The first positions 24A and 24A are, for example, the hole positions of the end portions on the base ends 21A and 21A side of the hole portions 24 and 24 which are elongated holes, and the second positions 24B and 24B are, for example, holes which are elongated holes. This is the hole position of the end portion on the tip 21B, 21B side of the portions 24, 24.
　図１１～図１３に示すように、アーム部２１，２１は、軸部１６，１６が穴部２４，２４の第一位置２４Ａ，２４Ａに位置する際に、蓋本体１０に対して回動可能となる形状であるとともに、軸部１６，１６が穴部２４，２４の第二位置２４Ｂ，２４Ｂに位置する際に、蓋本体１０に対して回動不能となる形状となっている。なお、図１１は、図３に示すＸＩ－ＸＩ線における断面図であり、図１３は、図１に示すＸＩＩＩ－ＸＩＩＩ線における断面図である。 As shown in FIGS. 11 to 13, the arm portions 21 and 21 can rotate with respect to the lid main body 10 when the shaft portions 16 and 16 are located at the first positions 24A and 24A of the hole portions 24 and 24. In addition to the shape, when the shaft portions 16 and 16 are located at the second positions 24B and 24B of the hole portions 24 and 24, the shape is such that they cannot rotate with respect to the lid main body 10. 11 is a cross-sectional view taken along the line XI-XI shown in FIG. 3, and FIG. 13 is a cross-sectional view taken along the line XIII-XIII shown in FIG.
　具体的に説明すると、収容凹部１４の底面１４Ａに垂直で軸部１６，１６の中心Ｏを通る線を、基準線Ａ，Ａとする。そして、軸部１６，１６が穴部２４，２４の第一位置２４Ａ，２４Ａに位置する際に（図１１及び図１２参照）、第一平面２１Ｄ，２１Ｄのアーム部２１，２１の基端２１Ａ，２１Ａ側の先端は、基準線Ａ，Ａ上、又は、基準線Ａ，Ａよりもアーム部２１，２１の先端２１Ｂ，２１Ｂ側に位置する。これにより、軸部１６，１６が穴部２４，２４の第一位置２４Ａ，２４Ａに位置する際は、アーム部２１，２１の第一平面２１Ｄ，２１Ｄが収容凹部１４，１４の底面１４Ａ，１４Ａに押し当てられることなく、蓋本体１０に対してハンドル２０を回動することができる。なお、軸部１６，１６が第二位置２４Ｂ，２４Ｂに位置している場合は、凹部１５に指を差し込み、凹部１５からハンドル２０を押すことで、軸部１６，１６を穴部２４，２４の第一位置２４Ａ，２４Ａに位置させることができる。 Specifically, the lines perpendicular to the bottom surface 14A of the accommodating recess 14 and passing through the center O of the shaft portions 16 and 16 are defined as reference lines A and A. Then, when the shaft portions 16 and 16 are located at the first positions 24A and 24A of the hole portions 24 and 24 (see FIGS. 11 and 12), the base ends 21A of the arm portions 21 and 21 of the first planes 21D and 21D are formed. , The tip on the 21A side is located on the reference lines A and A, or on the tip 21B and 21B side of the arm portions 21 and 21 with respect to the reference lines A and A. As a result, when the shaft portions 16 and 16 are located at the first positions 24A and 24A of the holes 24 and 24, the first planes 21D and 21D of the arm portions 21 and 21 are the bottom surfaces 14A and 14A of the accommodating recesses 14 and 14. The handle 20 can be rotated with respect to the lid body 10 without being pressed against the lid body 10. When the shaft portions 16 and 16 are located at the second positions 24B and 24B, the shaft portions 16 and 16 are formed into the holes 24 and 24 by inserting a finger into the recess 15 and pushing the handle 20 from the recess 15. It can be located at the first positions 24A and 24A of.
　また、軸部１６，１６が穴部２４，２４の第二位置２４Ｂ，２４Ｂに位置する際に（図１３参照）、第一平面２１Ｄ，２１Ｄのアーム部２１，２１の基端２１Ａ，２１Ａ側の先端は、基準線Ａ，Ａよりもアーム部２１，２１の基端２１Ａ，２１Ａ側に位置する。これにより、軸部１６，１６が穴部２４，２４の第二位置２４Ｂ，２４Ｂに位置する際は、蓋本体１０に対してハンドル２０を回動しようとしても、アーム部２１，２１の第一平面２１Ｄ，２１Ｄが収容凹部１４，１４の底面１４Ａ，１４Ａに押し当てられることで、蓋本体１０に対するハンドル２０の回動が阻止される。つまり、蓋本体１０に対してハンドル２０を所定の回動位置に維持することができる。なお、軸部１６，１６が第一位置２４Ａ，２４Ａに位置している場合は、蓋本体１０の側面１１Ｂ側からハンドル２０を押すことで、軸部１６，１６を穴部２４，２４の第二位置２４Ｂ，２４Ｂに位置させることができる。 Further, when the shaft portions 16 and 16 are located at the second positions 24B and 24B of the hole portions 24 and 24 (see FIG. 13), the base ends 21A and 21A sides of the arm portions 21 and 21 of the first planes 21D and 21D Is located closer to the base ends 21A and 21A of the arm portions 21 and 21 than the reference lines A and A. As a result, when the shaft portions 16 and 16 are located at the second positions 24B and 24B of the hole portions 24 and 24, even if the handle 20 is to be rotated with respect to the lid body 10, the first of the arm portions 21 and 21 When the flat surfaces 21D and 21D are pressed against the bottom surfaces 14A and 14A of the accommodating recesses 14 and 14, the rotation of the handle 20 with respect to the lid body 10 is prevented. That is, the handle 20 can be maintained at a predetermined rotation position with respect to the lid body 10. When the shaft portions 16 and 16 are located at the first positions 24A and 24A, the shaft portions 16 and 16 can be moved to the holes 24 and 24 by pushing the handle 20 from the side surface 11B side of the lid body 10. It can be located at two positions 24B and 24B.
　蓋本体１０に対してハンドル２０を所定の回動位置に維持する観点からは、穴部２４，２４の短軸の長さ（短径）は、軸部１６，１６の径と同じ、又は、軸部１６，１６が摺動可能な範囲で軸部１６，１６の径よりも小さくすることができる。これにより、軸部１６，１６と穴部２４，２４との間で適度の摩擦が生じるため、更に、蓋本体１０に対してハンドル２０を所定の回動位置に維持しやすくなる。 From the viewpoint of maintaining the handle 20 at a predetermined rotation position with respect to the lid body 10, the length (minor diameter) of the minor shafts of the holes 24 and 24 is the same as the diameters of the shaft portions 16 and 16 or The diameter of the shaft portions 16 and 16 can be made smaller than the diameter of the shaft portions 16 and 16 within a slidable range. As a result, an appropriate amount of friction is generated between the shaft portions 16 and 16 and the hole portions 24 and 24, so that the handle 20 can be easily maintained at a predetermined rotation position with respect to the lid body 10.
　また、円弧面２１Ｅ，２１Ｅの中心（円弧中心）は、軸部１６，１６が穴部２４，２４の第一位置２４Ａ，２４Ａに位置する際の軸部１６，１６の中心Ｏとなっている。更に、円弧面２１Ｅ，２１Ｅの半径（円弧半径）は、軸部１６，１６が穴部２４，２４の第一位置２４Ａ，２４Ａに位置する際の軸部１６，１６の中心Ｏから収容凹部１４，１４の底面１４Ａ，１４Ａまでの距離以下となっている。これにより、軸部１６，１６が穴部２４，２４の第一位置２４Ａ，２４Ａに位置する際は、アーム部２１，２１の円弧面２１Ｅ，２１Ｅが収容凹部１４，１４の底面１４Ａ，１４Ａに押し当てられないため、蓋本体１０に対してハンドルを回動することができる。 Further, the center of the arcuate surfaces 21E and 21E (center of the arc) is the center O of the shaft portions 16 and 16 when the shaft portions 16 and 16 are located at the first positions 24A and 24A of the hole portions 24 and 24. .. Further, the radius (arc radius) of the arcuate surfaces 21E and 21E is the accommodating recess 14 from the center O of the shaft portions 16 and 16 when the shaft portions 16 and 16 are located at the first positions 24A and 24A of the hole portions 24 and 24. , 14 is less than the distance to the bottom surfaces 14A, 14A. As a result, when the shaft portions 16 and 16 are located at the first positions 24A and 24A of the holes 24 and 24, the arcuate surfaces 21E and 21E of the arm portions 21 and 21 are placed on the bottom surfaces 14A and 14A of the accommodating recesses 14 and 14. Since it is not pressed, the handle can be rotated with respect to the lid body 10.
　以上説明したように、本実施形態では、ハンドル２０が蓋本体１０に対して回動可能に取り付けられているが、ロック機構を構成する軸部１６，１６と穴部２４，２４とにより、ハンドル２０を蓋本体１０に対して所定の回動位置に維持することができる。このため、例えば、鉛蓄電池１を車両に搭載した際に、ハンドル２０を蓋本体１０に対して所定の回動位置に維持しておくことで、車両が振動しても、ハンドル２０が蓋本体１０に衝突することによる振動の発生を抑制することができる。 As described above, in the present embodiment, the handle 20 is rotatably attached to the lid body 10, but the handle is formed by the shaft portions 16 and 16 and the hole portions 24 and 24 constituting the lock mechanism. 20 can be maintained at a predetermined rotation position with respect to the lid body 10. Therefore, for example, when the lead-acid battery 1 is mounted on the vehicle, the handle 20 is maintained at a predetermined rotation position with respect to the lid body 10, so that the handle 20 stays on the lid body even if the vehicle vibrates. It is possible to suppress the generation of vibration due to collision with 10.
　また、ハンドル２０を蓋本体１０の収容凹部１４に収容した状態に維持することができるため、ハンドル２０に邪魔されることなく鉛蓄電池１を車両に搭載することができる。 Further, since the handle 20 can be maintained in the state of being housed in the housing recess 14 of the lid main body 10, the lead storage battery 1 can be mounted on the vehicle without being disturbed by the handle 20.
　また、蓋本体１０に設けられた軸部１６，１６がハンドル２０に設けられた穴部２４，２４に嵌め込まれることで、蓋本体１０に対してハンドル２０を回動可能とすることができる。そして、この穴部２４，２４が、穴部２４，２４に嵌め込まれた軸部１６，１６が摺動可能な長穴であるため、穴部２４，２４に対する軸部１６，１６の位置を変えることで、軸部１６，１６を中心としたハンドル２０の回動半径を変えることができる。このため、例えば、軸部１６，１６を中心としたハンドル２０の回動半径の違いにより、ハンドル２０の回動軌跡と蓋本体１０との重なり具合が変わるように、軸部１６，１６の位置、穴部２４，２４の位置、及び穴部２４，２４の長さを設定する。これにより、穴部２４，２４に対する軸部１６，１６の位置を変えることにより、蓋本体１０に対してハンドル２０が回動可能となる状態と、蓋本体１０に対してハンドル２０が回動不能となる状態とを、切り換えることができる。具体的には、軸部１６，１６を穴部２４，２４の第一位置２４Ａ，２４Ａに位置させることで、蓋本体１０に対してアーム部２１，２１を回動可能とすることができる。一方で、軸部１６，１６が穴部２４，２４の第二位置２４Ｂ，２４Ｂに位置させることで、蓋本体１０に対してアーム部２１，２１を回動不能とすることができる。つまり、蓋本体１０に対してアーム部２１，２１を所定の回動位置で維持することができる。 Further, by fitting the shaft portions 16, 16 provided in the lid main body 10 into the holes 24, 24 provided in the handle 20, the handle 20 can be rotated with respect to the lid main body 10. Since the holes 24, 24 are elongated holes in which the shafts 16 and 16 fitted in the holes 24 and 24 are slidable, the positions of the shafts 16 and 16 with respect to the holes 24 and 24 are changed. As a result, the turning radius of the handle 20 centered on the shaft portions 16 and 16 can be changed. Therefore, for example, the positions of the shaft portions 16 and 16 change so that the degree of overlap between the rotation locus of the handle 20 and the lid body 10 changes depending on the difference in the turning radius of the handle 20 centered on the shaft portions 16 and 16. , The positions of the holes 24, 24, and the lengths of the holes 24, 24 are set. As a result, by changing the positions of the shaft portions 16 and 16 with respect to the holes 24 and 24, the handle 20 can be rotated with respect to the lid main body 10 and the handle 20 cannot be rotated with respect to the lid main body 10. It is possible to switch between the states where Specifically, by locating the shaft portions 16 and 16 at the first positions 24A and 24A of the hole portions 24 and 24, the arm portions 21 and 21 can be rotated with respect to the lid body 10. On the other hand, by locating the shaft portions 16 and 16 at the second positions 24B and 24B of the hole portions 24 and 24, the arm portions 21 and 21 can be made non-rotatable with respect to the lid main body 10. That is, the arm portions 21 and 21 can be maintained at a predetermined rotation position with respect to the lid main body 10.
　また、アーム部２１，２１の第二平面２１Ｆ，２１Ｆは、円弧面２１Ｅ，２１Ｅから延びるとともにハンドル２０が蓋本体１０に対して垂直に直立した際に収容凹部１４の底面１４Ａに面する。このため、蓋本体１０に対してハンドル２０を持ち上げると、アーム部２１，２１の第二平面２１Ｆ，２１Ｆが収容凹部１４の底面１４Ａに当接されることで、ハンドル２０が蓋本体１０に対して立ち上げられた状態で保持される。これにより、ハンドル２０を持ちやすくなる。 Further, the second planes 21F and 21F of the arm portions 21 and 21 extend from the arcuate surfaces 21E and 21E and face the bottom surface 14A of the accommodating recess 14 when the handle 20 stands upright with respect to the lid body 10. Therefore, when the handle 20 is lifted with respect to the lid body 10, the second planes 21F and 21F of the arm portions 21 and 21 are brought into contact with the bottom surface 14A of the accommodating recess 14, so that the handle 20 is brought into contact with the lid body 10. It is held in the launched state. This makes it easier to hold the handle 20.
　また、穴部２４，２４がアーム部２１，２１の軸線方向に延びているため、容易に、蓋本体１０に対してハンドル２０を回動可能としつつ、ロック機構により、蓋本体１０に対してハンドル２０を所定の回動位置に維持することができる。 Further, since the holes 24 and 24 extend in the axial direction of the arm portions 21 and 21, the handle 20 can be easily rotated with respect to the lid main body 10, and the lock mechanism allows the lid main body 10 to rotate. The handle 20 can be maintained at a predetermined rotation position.
　本発明は、上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない限り適宜変更が可能である。 The present invention is not limited to the above embodiment, and can be appropriately modified as long as it does not deviate from the gist of the present invention.
　例えば、上記実施形態では、ハンドルが二つのアーム部を備え、それぞれのアーム部にロック機構を設けるものとして説明したが、例えば、片方のアーム部にのみロック機構を設けるものとしてもよく、アーム部が一つのハンドルを用いるものとしてもよい。 For example, in the above embodiment, the handle is provided with two arm portions, and the lock mechanism is provided for each arm portion. However, for example, the lock mechanism may be provided for only one arm portion, and the arm portion may be provided. May use one handle.
　また、上記実施形態では、蓋本体の収容凹部は、蓋本体の天面及び蓋本体の側面に開放されているものとして説明したが、例えば、蓋本体の天面に開放されるが蓋本体の側面には開放されないものとしてもよい。図１４及び図１５に示す鉛蓄電池１Ａでは、収容凹部１４は、蓋本体１０Ａの天面１１Ａに開放されているが、蓋本体１０Ａの側面１１Ｂに開放されていない。つまり、Ｙ方向における第二収容部１４Ｄの両側は、蓋本体１０Ａの側面１１Ｂに開放されていない。このため、Ｙ方向における第二収容部１４Ｄの両側に凹部１５Ａ及び凹部１５Ｂが形成されている。凹部１５Ａ及び凹部１５Ｂは、上記実施形態の凹部１５と同様に、収容凹部１４に収容されたハンドル２０Ａを指などで引っ掛けるために天面１１Ａから窪んだ凹部である。これにより、凹部１５Ａ又は凹部１５Ｂからハンドル２０ＡをＹ方向に押すことができる。 Further, in the above embodiment, the storage recess of the lid body has been described as being open to the top surface of the lid body and the side surface of the lid body. For example, although it is opened to the top surface of the lid body, the lid body It may not be open to the side. In the lead-acid battery 1A shown in FIGS. 14 and 15, the accommodating recess 14 is open to the top surface 11A of the lid body 10A, but not to the side surface 11B of the lid body 10A. That is, both sides of the second accommodating portion 14D in the Y direction are not open to the side surfaces 11B of the lid body 10A. Therefore, recesses 15A and 15B are formed on both sides of the second accommodating portion 14D in the Y direction. The recess 15A and the recess 15B are recesses recessed from the top surface 11A for hooking the handle 20A housed in the storage recess 14 with a finger or the like, similarly to the recess 15 of the above embodiment. As a result, the handle 20A can be pushed in the Y direction from the recess 15A or the recess 15B.
　また、上記実施形態では、蓋本体に対してハンドルを回動可能に軸支する軸部及び穴部がロック機構を構成するものとして説明したが、例えば、このような軸部及び穴部とは別の要素によりロック機構を構成してもよい。例えば、図１６に示すように、蓋本体１０Ｂに、軸部とは別に凸部１８を形成するとともに、ハンドル２０に、穴部とは別に凹部２８を形成する。このようにしても、蓋本体１０Ｂに対してハンドル２０を回動させ、凸部１８を凹部２８に嵌め込むことで、蓋本体１０Ｂに対するハンドル２０の回動位置を維持させることができる。 Further, in the above embodiment, the shaft portion and the hole portion that rotatably support the handle with respect to the lid body have been described as forming the lock mechanism. However, for example, such a shaft portion and the hole portion are The locking mechanism may be configured by another element. For example, as shown in FIG. 16, a convex portion 18 is formed on the lid body 10B separately from the shaft portion, and a concave portion 28 is formed on the handle 20 separately from the hole portion. Even in this way, the rotation position of the handle 20 with respect to the lid main body 10B can be maintained by rotating the handle 20 with respect to the lid main body 10B and fitting the convex portion 18 into the concave portion 28.
