Description

本発明は、ブラケット、クリップ、ハーネス端子等の、被取付体（本体）にボルトによって装着される板部材の回り止め構造に関するものである。 The present invention relates to a structure for preventing rotation of a plate member such as a bracket, a clip, a harness terminal, and the like that is attached to a mounted body (main body) with bolts.

ブラケット等の板部材を一本のボルトで被取付体に固定する場合には、板部材の回り止めが必要となる。
このような回り止め構造として、板部材にボルト貫通孔の径方向外方に向かうアーム部を突設し、被取付体に同アーム部を係止する係止部を形成し、アーム部と係止部とを当接、係合させることにより板部材の回り止めを行う構造が公知である（特許文献１）。 When a plate member such as a bracket is fixed to the mounted body with a single bolt, it is necessary to prevent the plate member from rotating.
As such a detent structure, the plate member is provided with an arm portion projecting radially outward of the bolt through hole, and a locking portion for locking the arm portion is formed on the mounted body, and the arm portion is engaged. A structure in which a plate member is prevented from rotating by abutting and engaging with a stopper is known (Patent Document 1).

しかしながら、上記のような回り止め構造では、板部材に余分なアーム部を設けるので、板部材が大型化して取付け箇所が制約されると共にコストアップの要因ともなる。
また、被取付体にもアーム部のための係止部を形成する必要があるので、被取付体の材料量が増加し、重量増、コストアップを招くこととなる。 However, in the anti-rotation structure as described above, an extra arm portion is provided on the plate member, so that the plate member is enlarged and the mounting location is restricted, and the cost is increased.
Moreover, since it is necessary to form the latching | locking part for an arm part also to a to-be-attached body, the amount of materials of a to-be-attached body will increase, and it will cause a weight increase and a cost increase.

本発明は、上記のような課題に鑑み創案されたものであり、板部材の大型化を防止すると共に被取付体の材料増を抑制できる板部材の回り止め構造を提供することを目的としている。 The present invention has been devised in view of the above problems, and an object of the present invention is to provide a detent structure for a plate member that can prevent an increase in the size of the plate member and can suppress an increase in the material of the mounted body. .

上記の目的を達成するために、本発明の板部材の回り止め構造は、ボルトが挿通される貫通孔を備え、被取付体に形成された雌ネジに前記ボルトを螺合することによって前記被取付体に装着される板部材の回り止め構造であって、前記貫通孔の縁部に前記雌ネジの方向に向かって立設された突起部と、前記雌ネジが形成されたネジ穴に設けられ前記突起部が係合する溝部とを備えたことを特徴としている。 In order to achieve the above object, the rotation preventing structure for a plate member of the present invention includes a through-hole through which a bolt is inserted, and the bolt is screwed into a female screw formed in a mounted body. A rotation preventing structure for a plate member to be mounted on a mounting body, provided in a protruding portion erected in the direction of the female screw at an edge of the through hole and a screw hole in which the female screw is formed And a groove portion with which the protruding portion engages.

また、前記板部材は、板材から前記貫通孔に対応する部分の一部に前記突起部に相当する形状の舌片が残存するように打ち抜き加工することによって形成され、前記突起部は、前記舌片を曲折することによって形成されていることが好ましい。 Further, the plate member is formed by punching from a plate material so that a tongue piece having a shape corresponding to the protruding portion remains in a part of a portion corresponding to the through hole, and the protruding portion is It is preferably formed by bending a piece.

本発明によれば、板部材に余分なアーム部を設ける必要が無く、そのため被取付体にもアーム部のための係止部を形成する必要がなくなるので、板部材の大型化や被取付体の重量増が抑制でき、コストアップを防止できると共に板部材の取付け箇所の自由度が向上する。
また、板部材が、板材から貫通孔に対応する部分の一部に突起部に相当する形状の舌片が残存するように打ち抜き加工することによって形成され、突起部が、舌片を曲折することによって形成されていれば、本来、打ち抜き加工によって廃材となるボルトの貫通孔部分の板材を、前記突起部として利用できるので、材料の歩留まりを向上させることができる。 According to the present invention, it is not necessary to provide an extra arm portion on the plate member, and therefore, it is not necessary to form a locking portion for the arm portion on the mounted body. The weight increase of the plate member can be suppressed, the increase in cost can be prevented, and the degree of freedom of the plate member mounting location is improved.
Further, the plate member is formed by punching so that a tongue piece having a shape corresponding to the protruding portion remains in a part of the portion corresponding to the through hole from the plate material, and the protruding portion bends the tongue piece. Since the plate material of the through-hole portion of the bolt, which is essentially a waste material by punching, can be used as the protrusion, the yield of the material can be improved.

以下、図面を参照して本発明の実施形態を説明する。
なお、以下に示す実施形態はあくまでも例示に過ぎず、以下の実施形態で明示しない種々の変形や技術の適用を排除する意図はない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Note that the embodiment described below is merely an example, and there is no intention to exclude various modifications and technical applications that are not explicitly described in the following embodiment.

板部材としてのブラケット１０には、図示しないハーネス、コントロールワイヤ等を支持する支持部１２と、ボルトを挿通する貫通孔１４が穿設された基部１６と、貫通孔１４の縁部１８に立設された突起部２０とが設けられている。 A bracket 10 as a plate member is erected on a support portion 12 that supports a harness, a control wire, and the like (not shown), a base portion 16 in which a through hole 14 for inserting a bolt is formed, and an edge portion 18 of the through hole 14. Projecting portion 20 is provided.

一方、図示しないトランスミッションケース等の構造物（被取付体）の表面に形成されたボス部３０には、雌ネジ３２（図３参照）が形成されたネジ穴３４と、同ネジ穴３４の上端（開放端）から内部（底部）に向かって形成され前記突起部２０と係合可能な溝部３６とが設けられている。 On the other hand, a boss 30 formed on the surface of a structure (attached body) such as a transmission case (not shown) has a screw hole 34 in which a female screw 32 (see FIG. 3) is formed, and an upper end of the screw hole 34. A groove 36 that is formed from the (open end) toward the inside (bottom) and engageable with the protrusion 20 is provided.

図１，２から明らかなように、突起部２０は、前記ネジ穴３４方向に向かって縁部１８から立設されており、基部１６をボス部３０の上面に載置することにより溝部３６に係合するように構成されている。これらの突起部２０及び溝部３６により、本実施形態にかかる回り止め構造が構成されている。 As is apparent from FIGS. 1 and 2, the protrusion 20 is erected from the edge 18 toward the screw hole 34, and the base 16 is placed on the upper surface of the boss 30 to form the groove 36. It is configured to engage. The protrusion 20 and the groove 36 constitute a rotation preventing structure according to the present embodiment.

また、ブラケット１０は、板材から貫通孔１４に対応する部分の一部に突起部２０に相当する形状の舌片２０ａが残存するように打ち抜き加工することによって形成され、突起部２０は、この舌片２０ａを曲折することによって形成されている。つまり、突起部２０は、ブラケット１０を打ち抜き加工で成形する際、貫通孔１４部分に対応する板材の一部を、突起部２０の形状に相当する舌片２０ａとして縁部１８に連結して残すように打ち抜き加工を行い、その後に舌片２０ａをほぼ直角に曲折することによって形成されている。（図４参照） Further, the bracket 10 is formed by punching from a plate material so that a tongue piece 20a having a shape corresponding to the protruding portion 20 remains in a part of a portion corresponding to the through hole 14. It is formed by bending the piece 20a. That is, when the projection 20 is formed by punching the bracket 10, a part of the plate material corresponding to the through-hole 14 portion is left connected to the edge 18 as a tongue piece 20 a corresponding to the shape of the projection 20. In this way, the punching process is performed, and then the tongue piece 20a is bent substantially at a right angle. (See Figure 4)

そして、基部１６をボス部３０の上面に載置することで突起部２０と溝部３６とが係合するので、その後に、図示しないボルトを挿通して前記雌ネジ３２に螺着させることにより、ブラケット１０がボス部３０に固定されると共に前記突起部２０と溝部３６との係合によりブラケット１０の回り止めが成される。 And since the projection part 20 and the groove part 36 engage by mounting the base part 16 on the upper surface of the boss | hub part 30, after that, by inserting the bolt which is not shown in figure and screwing to the said female screw 32, The bracket 10 is fixed to the boss 30, and the rotation of the bracket 10 is prevented by the engagement of the protrusion 20 and the groove 36.

以上のように構成された本発明の一実施態様にかかる回り止め構造によれば、ブラケット１０に余分なアーム部を設ける必要が無く、そのためボス部３０及びその周辺にアーム部のための係止部を形成する必要がなくなるので、ブラケット１０の大型化やボス部３０が設けられる被取付体の重量増を抑制でき、コストアップを抑制できると共にブラケット１０の取付け箇所の自由度が向上する。
また、本来、打ち抜き加工によって廃材となるボルトの貫通孔１４部分の板材を、突起部２０として利用できるので、ブラケット１０を打ち抜き加工するために用意するブランク材（板材）を小型化でき、材料の歩留まりを向上させることができる。 According to the anti-rotation structure according to the embodiment of the present invention configured as described above, it is not necessary to provide an extra arm portion on the bracket 10, so that the boss portion 30 and the periphery thereof are latched for the arm portion. Since there is no need to form a portion, it is possible to suppress an increase in the size of the bracket 10 and an increase in the weight of the mounted body on which the boss portion 30 is provided.
In addition, since the plate material of the bolt through-hole 14 portion, which is originally a waste material by punching, can be used as the protrusion 20, the blank material (plate material) prepared for punching the bracket 10 can be reduced in size. Yield can be improved.

以上、本発明の実施形態を説明したが、本発明はかかる実施形態を適宜変形して実施することができる。
例えば、突起部２０を縁部１８に沿って複数個設けることも可能であり、一例としては、図５に示すように、二つの舌片２０ａ，２０ｂを残すように打ち抜き加工を行えば、二つの突起部を設けることができ、回り止めをより強固なものとすることができる。 Although the embodiments of the present invention have been described above, the present invention can be implemented by appropriately modifying such embodiments.
For example, it is possible to provide a plurality of protrusions 20 along the edge 18. For example, as shown in FIG. 5, if punching is performed so as to leave two tongue pieces 20 a and 20 b, Two protrusions can be provided, and the rotation stopper can be made stronger.
