　一般に、ナットが被締結物に食い込むのを防止したり、緩み止めのために、被締結物とナットとの間にワッシャーが介在されている。しかしながら、両端が閉鎖されている雄ネジ部材に対しては、ワッシャーを横からしか組み込むことができないという問題がある。また、ワッシャーを介在させるのを忘れてナットを締め付けてしまった場合、一旦締め付けたナットを取り外した上で雄ネジ部材にワッシャーを挿通しなければならず、作業効率が低下してしまうという問題もある。 Generally, a washer is interposed between the object to be fastened and the nut to prevent the nut from biting into the object to be fastened or to prevent the nut from loosening. However, the male screw member whose both ends are closed has a problem that the washer can be incorporated only from the side. In addition, if you forget to interpose the washer and tighten the nut, you must remove the tightened nut and then insert the washer into the male screw member, which reduces work efficiency. is there.
　このため、従来、ボルト等の雄ネジ部材に横から差し込み可能なワッシャーが提案されている。例えば、特開２００６－３１６８３１号公報に記載の開閉片付き座金は、座金の挿入穴から外径部へ切り抜き、この切り抜いた線に沿って左右にスリット溝を設け、該スリット溝の底部を屈曲可能とする開閉片を設けてなるものである（特許文献１）。これにより、横から着脱自在に挿入でき、座金のズレや脱落を防止できるとされている。 For this reason, conventionally, a washer that can be inserted into a male screw member such as a bolt from the side has been proposed. For example, a washer with an opening and closing piece described in JP-A-2006-316831 is cut out from an insertion hole of the washer to an outer diameter portion, and slit grooves are provided on the left and right along the cut line, and the bottom portion of the slit groove can be bent Opening and closing pieces are provided (Patent Document 1). Thereby, it can insert detachably from the side, and it is supposed that the slippage and dropping of a washer can be prevented.

　しかしながら、特許文献１に記載された発明においては、締め付けたナットを緩み止めするための構成については特段に配慮されておらず、緩み止め効果が低い。このため、たとえ強固にナットを締め付けたとしても、継続的に振動や衝撃を受ける場所での使用や長期間にわたる使用によりナットが緩んでしまって締め付け効果が低下するという問題がある。 However, in the invention described in Patent Document 1, the structure for preventing the tightened nut from being loosened is not particularly considered, and the effect of preventing loosening is low. For this reason, even if the nut is firmly tightened, there is a problem that the tightening effect is reduced due to the nut loosening due to use in a place where vibration or impact is continuously applied or long-term use.
　また、特許文献１の従来技術にも記載されているように、単に、挿入穴に連通するように一部を切り抜いて横から挿入可能とする座金も知られている。しかしながら、このような座金は、ナットが少しでも緩んでしまった場合、ボルトからずれたり、脱落してしまうおそれがある。 Also, as described in the prior art of Patent Document 1, there is also known a washer that can be simply inserted by cutting out a part so as to communicate with the insertion hole. However, such a washer may be displaced from the bolt or fall off if the nut is loosened even a little.
　さらに、特許文献１に記載の座金においては、開閉片を屈曲可能に構成するため、スリット溝の肉厚を極めて薄く（０．１～０．３ｍｍ）形成している。このため、そのスリット溝で折れやすく、作業者は慎重に扱わなければならないが、一般に作業現場では締結作業等が急いで進められているため、ワッシャーの取り扱いを慎重にさせるのは不便である。また、開閉片を複数回開閉させるとスリット溝が金属疲労を起こし、すぐに破断してしまうおそれもある。よって、再利用することが求められる現場での使用には不向きである。 Furthermore, in the washer described in Patent Document 1, the slit groove is formed to be extremely thin (0.1 to 0.3 mm) in order to bend the opening / closing piece. For this reason, it is easy to bend in the slit groove, and the operator must handle it carefully. However, since the fastening operation and the like are generally proceeded quickly at the work site, it is inconvenient to handle the washer carefully. Further, when the opening / closing piece is opened and closed a plurality of times, the slit groove may cause metal fatigue and may be broken immediately. Therefore, it is not suitable for use in the field where reuse is required.
　本発明は、このような問題点を解決するためになされたものであって、ボルト等の雄ネジ部材に横から差し込めることはもとより、分割ナットや開閉式ナットが開口するのを防止でき、締め付けたナットの緩み止め効果を高めるととともに、位置ズレや脱落を防止することができる差込ワッシャーを提供することを目的としている。 The present invention has been made to solve such problems, and can be prevented from being opened from a split nut or an open / close nut as well as being inserted into a male screw member such as a bolt from the side. An object of the present invention is to provide an insertion washer capable of enhancing the effect of preventing the tightened nut from being loosened and preventing displacement and dropping.

発明を実施するための形態BEST MODE FOR CARRYING OUT THE INVENTION
　以下、本発明に係る差込ワッシャーの第１実施形態について図面を用いて説明する。 Hereinafter, a first embodiment of an insertion washer according to the present invention will be described with reference to the drawings.
　図１に示すように、本第１実施形態の差込ワッシャー１Ａは、主として、雄ネジ部材２を挿通させる挿通孔１１と、差込ワッシャー１Ａを開閉させるように分断された分断開閉部１２と、この分断開閉部１２を開閉させるための開閉支点部１３と、ナット３に係合するナット係合部１４とを有している。以下、各構成部についてより詳細に説明する。 As shown in FIG. 1, the insertion washer 1A of the first embodiment mainly includes an insertion hole 11 through which the male screw member 2 is inserted, and a divided opening / closing portion 12 divided to open and close the insertion washer 1A. The opening / closing fulcrum part 13 for opening and closing the divided opening / closing part 12 and the nut engaging part 14 engaged with the nut 3 are provided. Hereinafter, each component will be described in more detail.
　挿通孔１１は、ボルト等の雄ネジ部材２を挿通させるための孔であり、雄ネジ部材２の直径よりもやや大径に形成されている。なお、本発明において、雄ネジ部材２とは、ボルト等のように、棒状または筒状に形成され、外周面に雄ネジを有している全てのものを含む。 The insertion hole 11 is a hole through which the male screw member 2 such as a bolt is inserted, and is formed to have a diameter slightly larger than the diameter of the male screw member 2. In the present invention, the male screw member 2 includes all members such as bolts that are formed in a rod shape or a cylindrical shape and have a male screw on the outer peripheral surface.
　分断開閉部１２は、差込ワッシャー１Ａを雄ネジ部材２に横から差し込めるように開閉するものである。たとえば、この分断開閉部１２は、図１に示すように、差込ワッシャー１Ａが幅方向に分断ないし容易に分断可能に構成されている。また、本第１実施形態において、分断開閉部１２によって分断された一端面には、膨拡凸部１２ａが突出形成されており、この膨拡凸部１２ａをほぼ隙間なく嵌合させる膨拡凹部１２ｂが他端面に形成されている。 The split opening / closing part 12 opens and closes so that the insertion washer 1A can be inserted into the male screw member 2 from the side. For example, as shown in FIG. 1, the dividing opening / closing portion 12 is configured such that the insertion washer 1A can be divided in the width direction or can be easily divided. Further, in the first embodiment, the one end face divided by the dividing opening / closing part 12 is formed with a bulging convex part 12a so that the bulging convex part 12a can be fitted with almost no gap. 12b is formed on the other end surface.
　開閉支点部１３は、分断開閉部１２を上下方向に開閉し易くするためのものである。具体的には、開閉支点部１３は、図１に示すように、分断開閉部１２を上下に開閉させる支点として変形可能に小幅に形成されている。前記開閉支点部１３の形成位置は、特に限定されないが、本第１実施形態においては、挿通孔１１を基準として分断開閉部１２と略対称位置に形成している。なお、開閉支点部１３の幅は、分断開閉部１２を開閉し易く、かつ、複数回開閉させても破断しない程度の幅に設定される。また、開閉支点部１３は、小幅に形成することによらず、回動可能な部材を介して開閉可能に構成してもよい。 The opening / closing fulcrum part 13 is for making it easy to open and close the divided opening / closing part 12 in the vertical direction. Specifically, as shown in FIG. 1, the opening / closing fulcrum part 13 is formed in a small width so as to be deformable as a fulcrum for opening and closing the divided opening / closing part 12. The formation position of the opening / closing fulcrum part 13 is not particularly limited, but in the first embodiment, the opening / closing fulcrum part 13 is formed at a position substantially symmetrical to the dividing opening / closing part 12 with the insertion hole 11 as a reference. The width of the opening / closing fulcrum portion 13 is set to a width that allows the divided opening / closing portion 12 to be easily opened and closed and does not break even when the opening / closing fulcrum portion 12 is opened and closed a plurality of times. Moreover, you may comprise the opening-and-closing fulcrum part 13 so that opening and closing is possible via the member which can be rotated, without forming in small width.
　ナット係合部１４は、ナット３に係合して緩み止め効果を高めるためのものである。本第１実施形態では、図１および図３に示すように、差込ワッシャー１Ａの上面において、一対のナット係合部１４，１４が、挿通孔１１の周縁部に沿って略円弧状に突出形成されている。また、各ナット係合部１４，１４は、ナット３の寸法公差に関係なく軸心方向へ移動するため、その外周縁側から内周縁側に向けて下方傾斜された略テーパ状に形成されている。 The nut engaging portion 14 is for engaging the nut 3 to enhance the loosening prevention effect. In the first embodiment, as shown in FIGS. 1 and 3, the pair of nut engaging portions 14, 14 project in a substantially arc shape along the peripheral edge portion of the insertion hole 11 on the upper surface of the insertion washer 1 </ b> A. Is formed. Further, the nut engaging portions 14 and 14 are formed in a substantially tapered shape inclined downward from the outer peripheral edge side toward the inner peripheral edge side in order to move in the axial direction regardless of the dimensional tolerance of the nut 3. .
　このような略円弧状であって略テーパ状の傾斜面を有することにより、ナットと当接する作用面が十分に確保され、ナットに対して締め付け効果を高めるとともに、差込ワッシャー１Ａにとっても分断開閉部１２に閉鎖方向へ締め付ける力が作用するため、相乗的に緩み止め効果を高めることが可能となる。換言すれば、ナット係合部１４は、ナット３を締め付けた際にそのテーパ状傾斜面において当該ナット３と係合するように大きさや傾斜角が定められている。 By having such a substantially arc-shaped and substantially tapered inclined surface, a working surface that comes into contact with the nut is sufficiently secured, and the tightening effect on the nut is enhanced, and also the opening and closing of the insertion washer 1A is separated. Since the force tightening in the closing direction acts on the portion 12, it is possible to synergistically enhance the loosening prevention effect. In other words, the size and the inclination angle of the nut engaging portion 14 are determined so that when the nut 3 is tightened, the nut engaging portion 14 is engaged with the nut 3 on the tapered inclined surface.
　なお、本発明に係るナット係合部１４は、上記の構成に限定されるものではなく、少なくともナット３の対称線に関して両側に、周方向に連続したナット係合部１４、または複数のナット係合部１４が配置されていればよい。また、そのナット係合部１４の長さも適宜選択してよい。 Note that the nut engaging portion 14 according to the present invention is not limited to the above-described configuration, and the nut engaging portion 14 that is continuous in the circumferential direction on at least both sides with respect to the symmetry line of the nut 3 or a plurality of nut engaging portions. The joint part 14 should just be arrange | positioned. Moreover, you may select the length of the nut engaging part 14 suitably.
　つぎに、以上のような構成を備えた本第１実施形態における差込ワッシャー１Ａの作用について説明する。 Next, the operation of the insertion washer 1A according to the first embodiment having the above-described configuration will be described.
　まず、本第１実施形態では、雄ネジ部材２に螺合するナット３として、図２に示すような差込ナット３を使用している。この差込ナット３は、屈曲可能な薄肉部３１を残すように切り込み３２が形成されている。このため、指の力で簡単に開閉することができ、雄ネジ部材２の所望の位置に途中から差し込んで螺合させられるようになっている。また、差込ナット３の上下面には、外周縁に沿ってテーパ部３３が形成されている。なお、薄肉部３１は、１．０ｍｍ以下に形成することが好ましい。また、差込ナット３は、市販品に切り込み加工してからメッキ等の処理を施すだけで安価に製造できる。 First, in the first embodiment, the insertion nut 3 as shown in FIG. 2 is used as the nut 3 screwed into the male screw member 2. The insertion nut 3 is formed with a cut 32 so as to leave a bendable thin portion 31. For this reason, it can be easily opened and closed by the force of a finger, and is inserted into a desired position of the male screw member 2 from the middle to be screwed together. A tapered portion 33 is formed on the upper and lower surfaces of the insertion nut 3 along the outer peripheral edge. In addition, it is preferable to form the thin part 31 in 1.0 mm or less. Further, the insertion nut 3 can be manufactured at a low cost simply by performing a process such as plating after being cut into a commercially available product.
　なお、差込ナット３の構成は、上記に限られるものではなく、一対のナット片を組み合わせてなる分割ナットや、ヒンジピン等により開閉可能に構成された開閉式ナット等のように、横から差し込み可能な差込ナット３であればよい。このような差込ナット３を本発明に係る差込ワッシャー１Ａと合わせて使用することで、より作業性のよい締結力にすぐれたファスナーが構成されることになる。 Note that the structure of the insertion nut 3 is not limited to the above, and is inserted from the side, such as a split nut formed by combining a pair of nut pieces, or an open / close nut configured to be opened and closed by a hinge pin or the like. Any possible insertion nut 3 may be used. By using such an insertion nut 3 together with the insertion washer 1A according to the present invention, a fastener excellent in fastening force with better workability is configured.
　本第１実施形態の差込ワッシャー１Ａを被締結物Ｘと差込ナット３との間に介在させて締め付ける場合、まず、雄ネジ部材２に横から差込ワッシャー１Ａを差し込んだ後、雄ネジ部材２に差込ナット３を螺合させる。このとき、分断開閉部１２の一方と他方に上下方向の力を加えると、図１に示すように、開閉支点部１３を支点にして容易に上下に開口する。これにより、分断開閉部１２を雄ネジ部材２の径以上に開口させれば、所望の位置に差込ワッシャー１Ａが迅速に介在される。なお、差込ワッシャー１Ａは、図１に示すように、予め上下に開口させた状態で流通させて、使用時には雄ネジ部材２に差し込んで閉じるだけの構成にしてもよい。 When the insertion washer 1A of the first embodiment is interposed between the fastened object X and the insertion nut 3, and tightened, first, the insertion washer 1A is inserted into the male screw member 2 from the side, and then the male screw The insertion nut 3 is screwed into the member 2. At this time, when a force in the vertical direction is applied to one and the other of the divided opening / closing part 12, the opening / closing fulcrum part 13 is easily opened up and down as shown in FIG. Thereby, if the parting opening-and-closing part 12 is opened more than the diameter of the external thread member 2, the insertion washer 1A will be quickly interposed in a desired position. As shown in FIG. 1, the insertion washer 1 </ b> A may be configured to circulate in a state where it is opened up and down in advance, and to be inserted into the male screw member 2 and closed at the time of use.
　また、本第１実施形態では、差込ナット３を使用しているため、差込ワッシャー１Ａと差込ナット３との取り付け順序はどちらからでもよい。しかしながら、通常の六角ナットを使用する場合であっても、差込ワッシャー１Ａは、雄ネジ部材２に横から差し込んで取り付けられる。このため、六角ナットを先に締め付けてしまっても、それを取り外すことなく差込ワッシャー１Ａを介在させることができ、締め付け作業が効率化および迅速化する。 Further, in the first embodiment, since the insertion nut 3 is used, the mounting order of the insertion washer 1A and the insertion nut 3 may be from either. However, even when a normal hex nut is used, the insertion washer 1A is attached by being inserted into the male screw member 2 from the side. For this reason, even if the hexagon nut is tightened first, the insertion washer 1A can be interposed without removing it, and the tightening work becomes efficient and quick.
　また、本第１実施形態の差込ワッシャー１Ａおよび差込ナット３は、例えば、軸線方向に垂設された２本の長い雄ネジ部材２と、これら雄ネジ部材２にその両端をナットとワッシャーで固定される複数の支持部材とからなる棚等に使用するのに好適である。具体的には、雄ネジ部材２の両端が塞がれていても、差込ワッシャー１Ａを横から差し込むことができるため、差込ナット３と合わせて用いれば支持部材を所望の位置に固定できる。このため、既に固定済みのナット３やワッシャーを取り外すことなく支持部材を増設しうる。また、既に固定済みのナット３やワッシャーを取り外すことなく不要となった支持部材を削除することもできる。 Further, the insertion washer 1A and the insertion nut 3 of the first embodiment include, for example, two long male screw members 2 suspended in the axial direction, and nuts and washers at both ends of these male screw members 2. It is suitable for use in a shelf or the like comprising a plurality of support members fixed by Specifically, even if both ends of the male screw member 2 are closed, the insertion washer 1A can be inserted from the side, so that when used together with the insertion nut 3, the support member can be fixed at a desired position. . For this reason, a support member can be expanded without removing the already fixed nut 3 and washer. Further, the support member that is no longer necessary can be deleted without removing the already fixed nut 3 or washer.
　さらに、本第１実施形態では、分断開閉部１２を閉じる際、膨拡凸部１２ａと膨拡凹部１２ｂとが、ほぼ密接状態で嵌合する。このため、差込ワッシャー１Ａは、水平方向へ拡げられる力が加わっても開口してしまうことがない。また、後述するように、差込ナット３の締め付けに伴って、ナット係合部１４に拡開方向の力が加わっても、容易に開口してしまうことがない。 Furthermore, in the first embodiment, when the dividing opening / closing part 12 is closed, the expansion / contraction convex part 12a and the expansion / contraction concave part 12b are fitted in a substantially intimate state. For this reason, the insertion washer 1A does not open even if a force that expands in the horizontal direction is applied. Further, as will be described later, even if a force in the expanding direction is applied to the nut engaging portion 14 as the insertion nut 3 is tightened, the nut does not easily open.
　つぎに、差込ナット３を締め付け方向に回転させると、軸線方向に沿って下方に螺進し差込ワッシャー１Ａに当接する。このとき、テーパ状に形成された各ナット係合部１４が、寸法公差に関係なく差込ナット３を軸心方向へ移動させるため、締め付け度合いを増大させ緩み止め効果を向上する。 Next, when the insertion nut 3 is rotated in the tightening direction, it is screwed downward along the axial direction and comes into contact with the insertion washer 1A. At this time, since each nut engaging part 14 formed in the taper shape moves the insertion nut 3 in the axial direction regardless of the dimensional tolerance, the tightening degree is increased and the loosening prevention effect is improved.
　また、本第１実施形態では、各ナット係合部１４が、締め付け動作に伴って差込ナット３のテーパ部３３から拡開方向の力を受けるため、差込ナット３のテーパ部３３に対し閉じる方向の反作用力を付与する。これにより、締め付け中に差込ナット３が開いてしまうことがなく、より強固に締結される。 Moreover, in this 1st Embodiment, since each nut engaging part 14 receives the force of the expansion direction from the taper part 33 of the insertion nut 3 in connection with clamping operation | movement, with respect to the taper part 33 of the insertion nut 3 Applies a reaction force in the closing direction. Thereby, the insertion nut 3 does not open during tightening, and is tightened more firmly.
　差込ナット３をさらに強く締め付けると、螺進しなくなった状態で締め付け作業が完了する。この状態では、図３に示すように、差込ナット３の下面が差込ワッシャー１Ａの上面に密着するとともに、差込ナット３のテーパ部３３がナット係合部１４のテーパ状の傾斜面に密着した状態で固定される。これにより、差込ワッシャー１Ａと差込ナット３との間に発生する摩擦抵抗が高められ、緩み止め効果がより高められる。 る と When the insertion nut 3 is tightened more strongly, the tightening operation is completed in a state where the screw does not advance. In this state, as shown in FIG. 3, the lower surface of the insertion nut 3 is in close contact with the upper surface of the insertion washer 1 </ b> A, and the tapered portion 33 of the insertion nut 3 is brought into a tapered inclined surface of the nut engaging portion 14. Fixed in close contact. Thereby, the frictional resistance which generate | occur | produces between 1 A of insertion washers and the insertion nut 3 is raised, and the loosening prevention effect is raised more.
　また、本第１実施形態では、ナット係合部１４が、差込ナット３のテーパ部３３に係合するため、差込ナット３が拡開してしまうのを防止する。さらに、仮に差込ナット３が多少緩んでしまっても、ナット係合部１４が、差込ナット３のテーパ部３３に引っ掛かるため、差込ワッシャー１Ａが位置ズレしたり脱落してしまうのを防止する。 In the first embodiment, the nut engaging portion 14 is engaged with the taper portion 33 of the insertion nut 3, so that the insertion nut 3 is prevented from expanding. Furthermore, even if the insertion nut 3 is somewhat loosened, the nut engaging portion 14 is caught by the taper portion 33 of the insertion nut 3, so that the insertion washer 1A is prevented from being displaced or dropped. To do.
　以上のような本第１実施形態によれば、以下のような効果を奏する。
１．ボルト等の雄ネジ部材２に横から差し込んで所望の位置に取り付けることできる。
２．両端が塞がれている雄ネジ部材２に対しても横から取り付けることができる。
３．ワッシャーを介在させるのを忘れて六角ナットを締め付けてしまった場合でも、当該六角ナットを取り外す必要がなく、締め付け作業を効率化および迅速化できる。
４．ナット３の寸法公差を吸収し、緩み止め効果を向上することができる。

　つぎに、本発明に係る差込ワッシャー１Ｂの第２実施形態について図面を参照しつつ説明する。なお、上述した第１実施形態の構成と同等または相当する構成については同一の符号を付し、再度の説明を省略する。 Next, a second embodiment of the insertion washer 1B according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected about the structure equivalent to the structure of 1st Embodiment mentioned above, or it abbreviate | omits description.
　本第２実施形態の差込ワッシャー１Ｂの特徴は、図４に示すように、第１実施形態の構成のうち、分断開閉部１２および開閉支点部１３の代わりに、差込開口部１５を有している点にある。 The feature of the insertion washer 1B of the second embodiment is that, as shown in FIG. It is in the point.
　差込開口部１５は、差込ワッシャー１Ｂを雄ネジ部材２に横から差し込むための開口である。本第２実施形態において、差込開口部１５は、図４に示すように、差込ワッシャー１Ｂが幅方向に雄ネジ部材２を挿通させる挿通孔１１の孔径寸法と略同一の寸法幅で分断開口されている。 The insertion opening 15 is an opening for inserting the insertion washer 1B into the male screw member 2 from the side. In the second embodiment, as shown in FIG. 4, the insertion opening 15 is divided by a width substantially the same as the hole diameter of the insertion hole 11 through which the male screw member 2 is inserted by the insertion washer 1 </ b> B in the width direction. It is open.
　また、差込ワッシャー１Ｂの上面には、図４および図５に示すように、挿通孔１１の周縁部に沿って略円弧状のナット係合部１４が突出形成されている。本第２実施形態において、ナット係合部１４は、第１実施形態と同様、その外周縁側から内周縁側に向けて下方傾斜された略テーパ状に形成されており、この内側にナット３が座するようになっている。 Further, as shown in FIGS. 4 and 5, a substantially arc-shaped nut engaging portion 14 protrudes from the upper surface of the insertion washer 1 </ b> B along the peripheral portion of the insertion hole 11. In the second embodiment, the nut engaging portion 14 is formed in a substantially tapered shape inclined downward from the outer peripheral edge side toward the inner peripheral edge side, as in the first embodiment. Sit down.
　なお、本第２実施形態において、差込ワッシャー１Ｂには、後述する第３実施形態で組み合わされる補助ワッシャー５の円弧状収容凸部５４を遊嵌させる円弧状収容凹部１６が形成されている。この円弧状収容凹部１６は、図４および図５に示すように、差込ワッシャー１Ｂの下面において、ナット係合部１４の略円弧形状に合わせて凹状に形成されている。 In the second embodiment, the insertion washer 1B is formed with an arcuate accommodation recess 16 into which the arcuate accommodation projection 54 of the auxiliary washer 5 combined in the third embodiment to be described later is loosely fitted. As shown in FIGS. 4 and 5, the arcuate accommodation recess 16 is formed in a concave shape on the lower surface of the insertion washer 1 </ b> B in accordance with the substantially arcuate shape of the nut engaging portion 14.
　以上の構成を備えた本第２実施形態の差込ワッシャー１Ｂを被締結物Ｘと差込ナット３との間に介在させて締め付ける場合、まず、雄ネジ部材２に横から差込ワッシャー１Ｂを差し込んだ後、雄ネジ部材２に差込ナット３を螺合させる。このとき、差込開口部１５は雄ネジ部材２を容易に挿通孔１１へ導入し、差込ワッシャー１Ｂを所望の位置に迅速に介在させられる。 When the insertion washer 1B of the second embodiment having the above configuration is interposed between the fastened object X and the insertion nut 3 and tightened, first, the insertion washer 1B is first attached to the male screw member 2 from the side. After the insertion, the insertion nut 3 is screwed into the male screw member 2. At this time, the insertion opening 15 easily introduces the male screw member 2 into the insertion hole 11, and the insertion washer 1B can be quickly interposed at a desired position.
　つぎに、差込ナット３を締め付け方向に回転させると、軸線方向に沿って下方に螺進し差込ワッシャー１Ｂに当接する。このとき、ナット係合部１４のテーパ状傾斜面によって、寸法公差に関係なく差込ナット３を軸心方向へ移動させられるため、締め付け度合いを増大させて緩み止め効果を向上させられる。 Next, when the insertion nut 3 is rotated in the tightening direction, it is screwed downward along the axial direction and comes into contact with the insertion washer 1B. At this time, the insertion nut 3 can be moved in the axial direction regardless of the dimensional tolerance by the tapered inclined surface of the nut engaging portion 14, so that the tightening degree can be increased and the loosening prevention effect can be improved.
　さらに、差込ナット３を強く締め付けると、螺進しなくなった状態で締め付け作業が完了する。このとき、差込ワッシャー１Ｂの差込開口部１５と、差込ナット３の切り込み３２とが略直交する位置関係にて止めると、差込開口部１５と切り込み３２とが互いに閉口する力を作用させるため、緩み難くできる。なお、締め付けに際しては、差込ワッシャー１Ｂの差込開口部１５と、差込ナット３の切り込み３２とが略直交した状態で、両者を同時に締め付けるようにしてもよい。 Furthermore, if the insertion nut 3 is tightened strongly, the tightening operation is completed in a state where the screw does not advance. At this time, if the insertion opening 15 of the insertion washer 1B and the notch 32 of the insertion nut 3 are stopped in a substantially orthogonal relationship, a force is applied to close the insertion opening 15 and the notch 32. This makes it difficult to loosen. When tightening, the insertion opening 15 of the insertion washer 1B and the notch 32 of the insertion nut 3 may be tightened at the same time in a state of being substantially orthogonal.
　また、本第２実施形態では、差込ワッシャー１Ｂの下面に円弧状収容凹部１６が形成されているため、締め付け完了時に、差込ワッシャー１Ｂの下面が被締結物Ｘ側へ押されるように弾性変形させてもよい。この弾性力による反発力を差込ナット３が受けて、振動や衝撃に対する緩み止め効果を向上させられる。さらに、締め付け完了後は、図５に示すように、差込ナット３の下面が差込ワッシャー１Ｂの上面に密着するとともに、差込ナット３のテーパ部３３がナット係合部１４に密着した状態で固定される。これにより、差込ワッシャー１Ｂと差込ナット３との間に発生する摩擦抵抗が高められ、緩み止め効果がより一層向上する。 In the second embodiment, since the arcuate accommodation recess 16 is formed on the lower surface of the insertion washer 1B, the lower surface of the insertion washer 1B is elastic so that the lower surface of the insertion washer 1B is pushed to the fastened object X side when tightening is completed. It may be deformed. The insertion nut 3 receives the repulsive force due to this elastic force, and the effect of preventing loosening against vibration and impact can be improved. Furthermore, after completion of the tightening, as shown in FIG. 5, the bottom surface of the insertion nut 3 is in close contact with the upper surface of the insertion washer 1B, and the tapered portion 33 of the insertion nut 3 is in close contact with the nut engaging portion 14. It is fixed with. Thereby, the frictional resistance which generate | occur | produces between the insertion washer 1B and the insertion nut 3 is raised, and the loosening prevention effect improves further.
　以上のような本第２実施形態によれば、第１実施形態の効果１～６に加えて、以下のような効果を奏する。
１．差込ワッシャー１Ｂが簡単な構造であるため安価に製造できる。
２．雄ネジ部材２に対して極めて差し込みし易い。
３．差込開口部１５を大きく開口させているが、差込ナット３の締め付け位置を直交させることによって緩み止め効果を十分に発揮させられる。
４．差込ワッシャー１Ｂの円弧状収容凹部１６を弾性変形させるように差込ナット３を締め付けることで緩み止め効果を向上することができる。 According to the second embodiment as described above, in addition to the effects 1 to 6 of the first embodiment, the following effects can be obtained.
1. Since the insertion washer 1B has a simple structure, it can be manufactured at a low cost.
2. It is very easy to insert into the male screw member 2.
3. Although the insertion opening 15 is greatly opened, the loosening prevention effect can be sufficiently exhibited by making the tightening position of the insertion nut 3 orthogonal.
4). The loosening prevention effect can be improved by tightening the insertion nut 3 so as to elastically deform the arcuate accommodation recess 16 of the insertion washer 1B.
　つぎに、本発明に係る差込ワッシャー１Ｃの第３実施形態について図面を参照しつつ説明する。なお、上述した第１実施形態および第２実施形態の構成と同等または相当する構成については同一の符号を付し、再度の説明を省略する。 Next, a third embodiment of the insertion washer 1C according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected about the structure equivalent to or equivalent to the structure of 1st Embodiment mentioned above, and 2nd Embodiment, and description is abbreviate | omitted again.
　本第３実施形態の差込ワッシャー１Ｃの特徴は、図６に示すように、第２実施形態の差込ワッシャー１Ｂと組み合わせて使用する補助ワッシャー５を有している点にある。 The feature of the insertion washer 1C of the third embodiment is that it has an auxiliary washer 5 used in combination with the insertion washer 1B of the second embodiment, as shown in FIG.
　補助ワッシャー５は、図６および図７に示すように、主として、雄ネジ部材２を挿通させる補助側挿通孔５１と、この補助側挿通孔５１に雄ネジ部材２を横から差し込ませる補助側差込開口部５２と、ナット３に係合する補助側ナット係合部５３と、差込ワッシャー１Ｂと組み合わせるための円弧状収容凸部５４とを有している。 As shown in FIGS. 6 and 7, the auxiliary washer 5 mainly includes an auxiliary side insertion hole 51 through which the male screw member 2 is inserted, and an auxiliary side difference through which the male screw member 2 is inserted from the side into the auxiliary side insertion hole 51. It has the insertion opening 52, the auxiliary | assistant side nut engaging part 53 engaged with the nut 3, and the circular arc-shaped accommodation convex part 54 for combining with the insertion washer 1B.
　補助側差込開口部５２は、補助ワッシャー５を雄ネジ部材２に横から差し込むための開口である。本第３実施形態において、補助側差込開口部５２は、図７に示すように、その幅方向に雄ネジ部材２を挿通させる補助側挿通孔５１の孔径寸法と略同一の寸法幅で分断開口されている。換言すれば、当該補助側差込開口部５２は、前述した差込ワッシャー１Ｂの差込開口部１５と等しい形状に形成されている。 The auxiliary side insertion opening 52 is an opening for inserting the auxiliary washer 5 into the male screw member 2 from the side. In the third embodiment, as shown in FIG. 7, the auxiliary-side insertion opening 52 is divided by a width substantially the same as the diameter of the auxiliary-side insertion hole 51 through which the male screw member 2 is inserted in the width direction. It is open. In other words, the auxiliary side insertion opening 52 is formed in the same shape as the insertion opening 15 of the insertion washer 1B described above.
　補助側ナット係合部５３は、ナット３に係合して緩み止め効果を向上するためのものである。本第３実施形態において、補助側ナット係合部５３は、図６および図７に示すように、補助ワッシャー５の上面において、差込ワッシャー１Ｂの差込開口部１５と略同一の寸法幅であって、差込ワッシャー１Ｂのナット係合部１４と略同一の曲率半径を有する略円弧状に突出形成されている。 The auxiliary side nut engaging portion 53 is for engaging with the nut 3 to improve the loosening prevention effect. In the third embodiment, as shown in FIGS. 6 and 7, the auxiliary side nut engaging portion 53 has substantially the same dimensional width as the insertion opening 15 of the insertion washer 1 </ b> B on the upper surface of the auxiliary washer 5. Thus, it is formed to project in a substantially arc shape having a radius of curvature substantially the same as the nut engaging portion 14 of the insertion washer 1B.
　円弧状収容凸部５４は、差込ワッシャー１Ｂの下面に設けられた円弧状収容凹部１６と重ねて組み合わせるものである。すなわち、本第３実施形態では、図５に示すように、差込ワッシャー１Ｂの下面には、ナット係合部１４の裏側に沿って円弧状収容凹部１６が設けられている。そして、この円弧状収容凹部１６に下方から遊嵌するように、補助側ナット係合部５３以外の上面に円弧状収容凸部５４が突出形成されている。この円弧状収容凸部５４は、図７に示すように、差込ワッシャー１Ｂの円弧状収容凹部１６内に重ねられて収容可能な形状に形成されている。 The arcuate accommodation convex portion 54 is combined with the arcuate accommodation concave portion 16 provided on the lower surface of the insertion washer 1B. That is, in the third embodiment, as shown in FIG. 5, an arcuate accommodation recess 16 is provided along the back side of the nut engaging portion 14 on the lower surface of the insertion washer 1B. An arcuate accommodation convex portion 54 is formed on the upper surface other than the auxiliary nut engaging portion 53 so as to loosely fit into the arcuate accommodation recess 16 from below. As shown in FIG. 7, the arcuate accommodation convex portion 54 is formed in a shape that can be accommodated by being overlapped with the arcuate accommodation recess 16 of the insertion washer 1 </ b> B.
　以上の構成を備えた本第３実施形態の差込ワッシャー１Ｃを被締結物Ｘと差込ナット３との間に介在させて締め付ける場合、まず、雄ネジ部材２に横から差込ワッシャー１Ｂおよび補助ワッシャー５を差し込んだ後、雄ネジ部材２に差込ナット３を螺合させる。このとき、差込ワッシャー１Ｂを雄ネジ部材２の上方に差し込む一方、この差込方向と逆方向から補助ワッシャー５を雄ネジ部材２の下方に差し込む。 When the insertion washer 1C of the third embodiment having the above configuration is interposed between the fastened object X and the insertion nut 3, and tightened, first, the insertion washer 1B and After the auxiliary washer 5 is inserted, the insertion nut 3 is screwed into the male screw member 2. At this time, the insertion washer 1B is inserted above the male screw member 2, while the auxiliary washer 5 is inserted below the male screw member 2 from the opposite direction to the insertion direction.
　そして、差込ワッシャー１Ｂと補助ワッシャー５とを上下に重ね合わせると、補助側ナット係合部５３が、差込ワッシャー１Ｂの差込開口部１５に嵌合する。これにより、図６に示すように、差込開口部１５が閉じられるとともに、ナット係合部１４と補助側ナット係合部５３とが周方向に連続的に構成される。また、補助ワッシャー５の円弧状収容凸部５４が、差込ワッシャー１Ｂの円弧状収容凹部１６に遊嵌するため、差込ワッシャー１Ｂと補助ワッシャー５との位置ズレや脱落を相互に防止する。 Then, when the insertion washer 1B and the auxiliary washer 5 are vertically overlapped, the auxiliary side nut engaging portion 53 is fitted into the insertion opening 15 of the insertion washer 1B. Thereby, as shown in FIG. 6, the insertion opening 15 is closed, and the nut engaging portion 14 and the auxiliary side nut engaging portion 53 are continuously configured in the circumferential direction. Further, since the arcuate accommodation convex portion 54 of the auxiliary washer 5 is loosely fitted into the arcuate accommodation recess 16 of the insertion washer 1B, misalignment and drop-off of the insertion washer 1B and the auxiliary washer 5 are mutually prevented.
　つぎに、差込ナット３を締め付け方向に回転させると、軸線方向に沿って下方に螺進し差込ワッシャー１Ｃに当接する。このため、ナット係合部１４および補助側ナット係合部５３の各テーパ状傾斜面が、寸法公差に関係なく差込ナット３を軸心方向へ移動させるため、締め付け度合いを増大させ緩み止め効果を向上する。 Next, when the insertion nut 3 is rotated in the tightening direction, it is screwed downward along the axial direction and comes into contact with the insertion washer 1C. For this reason, the tapered inclined surfaces of the nut engaging portion 14 and the auxiliary nut engaging portion 53 move the insertion nut 3 in the axial direction regardless of the dimensional tolerance, thereby increasing the degree of tightening and preventing the loosening effect. To improve.
　さらに、差込ナット３を強く締め付けると、螺進しなくなった状態で締め付け作業が完了する。この状態では、図８に示すように、差込ナット３の下面が差込ワッシャー１Ｂおよび補助ワッシャー５の上面に密着するとともに、差込ナット３のテーパ部３３がナット係合部１４および補助側ナット係合部５３に密着した状態で固定される。これにより、差込ワッシャー１Ｂおよび補助ワッシャー５と差込ナット３との間に発生する摩擦抵抗が高められ、緩み止め効果が向上する。 Furthermore, if the insertion nut 3 is tightened strongly, the tightening operation is completed in a state where the screw does not advance. In this state, as shown in FIG. 8, the lower surface of the insertion nut 3 is in close contact with the upper surfaces of the insertion washer 1B and the auxiliary washer 5, and the tapered portion 33 of the insertion nut 3 is connected to the nut engaging portion 14 and the auxiliary side. It is fixed in close contact with the nut engaging portion 53. Thereby, the frictional resistance which generate | occur | produces between the insertion washer 1B and the auxiliary washer 5, and the insertion nut 3 is raised, and the loosening prevention effect improves.
　なお、本第３実施形態では、補助ワッシャー５の下面にも、円弧状収容凸部５４の裏側に沿って凹状の空間が形成されている。このため、締め付け完了時に、補助ワッシャー５の下面が被締結物Ｘ側に押し出すように弾性変形させてもよい。この弾性力による差込ナット３への反発力によって、振動や衝撃に対する緩み止め効果がより一層向上する。 In the third embodiment, a concave space is formed on the lower surface of the auxiliary washer 5 along the back side of the arcuate accommodation convex portion 54. For this reason, when the tightening is completed, the lower surface of the auxiliary washer 5 may be elastically deformed so as to be pushed out to the fastened object X side. Due to the repulsive force on the insertion nut 3 due to this elastic force, the effect of preventing loosening against vibration and impact is further improved.
　以上のような本第３実施形態によれば、第２実施形態の効果に加えて、以下のような効果を奏する。
１．ナット係合部１４および補助側ナット係合部５３を周方向に連続的に構成されるため、緩み止め効果を向上することができる。
２．差込ワッシャー１Ｂと補助ワッシャー５とを組み合わせることで、相互に位置ズレや脱落を防止することができる。 According to the third embodiment as described above, the following effects can be obtained in addition to the effects of the second embodiment.
1. Since the nut engaging part 14 and the auxiliary side nut engaging part 53 are continuously comprised in the circumferential direction, the loosening prevention effect can be improved.
2. By combining the insertion washer 1 </ b> B and the auxiliary washer 5, it is possible to prevent misalignment or dropout.
　つぎに、本発明に係る差込ワッシャー１Ｄの第４実施形態について図面を参照しつつ説明する。なお、上述した第１実施形態から第３実施形態の構成と同等または相当する構成については同一の符号を付し、再度の説明を省略する。 Next, a fourth embodiment of the insertion washer 1D according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected about the structure equivalent to the structure of 1st Embodiment mentioned above-3rd Embodiment, or it abbreviate | omits.
　本第４実施形態の差込ワッシャー１Ｄの特徴は、図９に示すように、同一形状に形成された一対のワッシャーピース６，６を組み合わせて構成される点にある。 The feature of the insertion washer 1D of the fourth embodiment is that it is configured by combining a pair of washer pieces 6 and 6 formed in the same shape as shown in FIG.
　各ワッシャーピース６は、図９および図１０に示すように、主として、雄ネジ部材２を挿通させる挿通孔１１と、この挿通孔１１を雄ネジ部材２に対して横から差し込むために開口された差込開口部１５と、ナット３に係合させるナット係合部１４と、組み合わせる相手方のワッシャーピース６を重ねた際に嵌り合う嵌合凹部１７および嵌合凸部１８とを有している。 As shown in FIGS. 9 and 10, each washer piece 6 is mainly opened to insert an insertion hole 11 through which the male screw member 2 is inserted, and the insertion hole 11 from the side to the male screw member 2. It has the insertion opening part 15, the nut engaging part 14 engaged with the nut 3, and the fitting recessed part 17 and the fitting convex part 18 which fit when the other washer piece 6 to combine is piled up.
　本第４実施形態において、差込開口部１５は、挿通孔１１の位置で幅方向に分断開口されている。そして、この差込開口部１５を構成する両端部に他方のワッシャーピース６と相互に嵌合する嵌合凹部１７と嵌合凸部１８とがそれぞれ形成されている。嵌合凸部１８は、図９に示すように、差込開口部１５を構成する両端部の先端において軸線方向に突出するように構成されている。一方、嵌合凹部１７は、前記嵌合凸部１８の基端側において差込ワッシャーの厚さの半分より薄い厚さに形成されており、他方のワッシャーピースの嵌合凸部１８を嵌合しうる凹状に形成されている。 In the fourth embodiment, the insertion opening 15 is divided and opened in the width direction at the position of the insertion hole 11. And the fitting recessed part 17 and the fitting convex part 18 which are mutually fitted with the other washer piece 6 are formed in the both ends which comprise this insertion opening part 15, respectively. The fitting convex part 18 is comprised so that it may protrude in an axial direction in the front-end | tip of the both ends which comprise the insertion opening part 15, as shown in FIG. On the other hand, the fitting concave portion 17 is formed on the proximal end side of the fitting convex portion 18 so as to be thinner than half of the thickness of the insertion washer, and the fitting convex portion 18 of the other washer piece is fitted. It is formed in a concave shape that can be.
　また、ナット係合部１４は、図１０に示すように、各ワッシャーピース６，６の上下面に形成されている。本第４実施形態において、ナット係合部１４は、差込開口部１５の周縁に沿って略円弧状に突出形成されており、その外周縁側から内周縁側に向けて下方傾斜された略テーパ状を構成している。そして、一対のワッシャーピース６，６を上下に重ねて組み合わせたとき、一方のワッシャーピース６の上面に形成されたナット係合部１４と、他方のワッシャーピース６の下面に形成されたナット係合部１４とが、挿入孔１１の周りに傾斜面がリング状に連続したナット係合部１４を構成するようになっている。 Moreover, the nut engaging part 14 is formed in the upper and lower surfaces of each washer piece 6 and 6, as shown in FIG. In the fourth embodiment, the nut engaging portion 14 is formed so as to protrude in a substantially arc shape along the peripheral edge of the insertion opening 15, and is substantially tapered inclined downward from the outer peripheral edge side toward the inner peripheral edge side. It constitutes the shape. And when a pair of washer pieces 6 and 6 are piled up and down, a nut engaging part 14 formed on the upper surface of one washer piece 6 and a nut engagement formed on the lower surface of the other washer piece 6 are combined. The portion 14 constitutes a nut engaging portion 14 in which an inclined surface continues in a ring shape around the insertion hole 11.
　これにより、上面にはナット係合部１４が形成され、下面にはナット係合部１４と同一形状の隙間が形成される。下面側の隙間は差込ナット３を締め付けた際の弾力を奏する機能を兼ね備えることが可能である。なお、ナット係合部１４は、周方向に連続的に構成されているが、差込ナット３の締め付け力を保持し得れば、傾斜面が分断されている部分が存在しても構わない。 Thus, the nut engaging portion 14 is formed on the upper surface, and a gap having the same shape as the nut engaging portion 14 is formed on the lower surface. The gap on the lower surface side can also have a function of exerting elasticity when the insertion nut 3 is tightened. In addition, although the nut engaging part 14 is comprised continuously in the circumferential direction, as long as the clamping force of the insertion nut 3 can be hold | maintained, the part into which the inclined surface is divided | segmented may exist. .
　以上の構成を備えた本第４実施形態の差込ワッシャー１Ｄを被締結物Ｘと差込ナット３との間に介在させて締め付ける場合、まず、雄ネジ部材２に横から差込ワッシャー１Ｄを差し込んだ後、雄ネジ部材２に差込ナット３を螺合させる。このとき、それぞれのワッシャーピース６を互いの嵌合凹部１７および嵌合凸部１８が向かい合うように上下に差し込む。各ワッシャーピース６，６は、同一形状に形成されているため、作業者が取り違えることがなく作業効率が高い。 When the insertion washer 1D of the fourth embodiment having the above configuration is interposed between the fastened object X and the insertion nut 3, and tightened, first, the insertion washer 1D is inserted into the male screw member 2 from the side. After the insertion, the insertion nut 3 is screwed into the male screw member 2. At this time, each washer piece 6 is inserted up and down so that the fitting concave portion 17 and the fitting convex portion 18 face each other. Since each washer piece 6 and 6 is formed in the same shape, an operator does not mix up and work efficiency is high.
　そして、各ワッシャーピース６，６を上下に重ね合わせると、一方のワッシャーピース６の嵌合凸部１８が、他方のワッシャーピース６の嵌合凹部１７に嵌合するとともに、他方のワッシャーピース６の嵌合凸部１８が一方のワッシャーピース６の嵌合凹部１７に嵌合する。このため、差込ワッシャー１Ｄは、水平方向へ拡げられる力が加わっても外れない。また、差込ナット３の締め付けに伴って、ナット係合部１４に拡開方向の力が加わっても外れないように作用する。 Then, when the washer pieces 6, 6 are stacked one above the other, the fitting convex portion 18 of one washer piece 6 is fitted into the fitting concave portion 17 of the other washer piece 6 and the other washer piece 6 The fitting convex part 18 fits into the fitting concave part 17 of one washer piece 6. For this reason, the insertion washer 1D does not come off even when a force that expands in the horizontal direction is applied. Further, as the insertion nut 3 is tightened, the nut engaging portion 14 acts so that it does not come off even if a force in the expanding direction is applied.
　また、本第４実施形態では、図９に示すように、各ワッシャーピース６，６を組み合わせるだけで、それぞれの差込開口部１５が互いに閉じられるとともに、テーパ状傾斜面を備えたナット係合部１４が挿入孔１１の周りに連続的に構成される。 Moreover, in this 4th Embodiment, as shown in FIG. 9, only by combining each washer piece 6 and 6, each insertion opening part 15 is mutually closed, and nut engagement provided with the tapered inclined surface The portion 14 is continuously formed around the insertion hole 11.
　つぎに、差込ナット３を締め付け方向に回転させると、軸線方向に沿って下方に螺進し差込ワッシャー１Ｄに当接する。このため、ナット係合部１４のテーパ状傾斜面が、寸法公差に関係なく差込ナット３を軸心方向へ移動させるため、締め付け度合いを増大させ緩み止め効果を向上する。 Next, when the insertion nut 3 is rotated in the tightening direction, it is screwed downward along the axial direction and comes into contact with the insertion washer 1D. For this reason, since the tapered inclined surface of the nut engaging portion 14 moves the insertion nut 3 in the axial direction regardless of the dimensional tolerance, the tightening degree is increased and the loosening prevention effect is improved.
　さらに、差込ナット３を強く締め付けると、螺進しなくなった状態で締め付け作業が完了する。この状態では、図１０に示すように、差込ナット３の下面が差込ワッシャー１Ｄの上面に密着するとともに、差込ナット３のテーパ部３３がナット係合部１４に密着した状態で固定される。これにより、差込ワッシャー１Ｄと差込ナット３との間に発生する摩擦抵抗が高められ、緩み止め効果が向上する。 Furthermore, if the insertion nut 3 is tightened strongly, the tightening operation is completed in a state where the screw does not advance. In this state, as shown in FIG. 10, the lower surface of the insertion nut 3 is fixed in contact with the upper surface of the insertion washer 1D, and the tapered portion 33 of the insertion nut 3 is fixed in contact with the nut engaging portion 14. The Thereby, the frictional resistance which generate | occur | produces between the insertion washer 1D and the insertion nut 3 is raised, and the loosening prevention effect improves.
　また、図１０に示すように、差込ナット３の固定位置は、差込ワッシャー１Ｄに対して、切り込み３２が各ワッシャーピース６，６の分割方向と直交する方向に位置されていることが緩み止め効果を高める点から好ましい。 Further, as shown in FIG. 10, the fixing position of the insertion nut 3 is loose with respect to the insertion washer 1D in that the notch 32 is positioned in a direction perpendicular to the dividing direction of the washer pieces 6 and 6. This is preferable from the viewpoint of enhancing the stopping effect.
　また、本第４実施形態では、各ワッシャーピース６，６が同一形状に形成されているため、図１０に示すように、下面側のナット係合部１４が、被締結物Ｘとの間にアーチ状の空間を形成する。このため、締め付け完了時に、差込ワッシャー１Ｄの下面が被締結物Ｘ側に押し出されるようにして弾性変形することが可能である。この弾性力による差込ナット３への反発力によって、振動や衝撃に対する緩み止め効果がより一層向上する。 In the fourth embodiment, since the washer pieces 6 and 6 are formed in the same shape, the nut engaging portion 14 on the lower surface side is between the fastened object X as shown in FIG. An arched space is formed. For this reason, it is possible to elastically deform so that the lower surface of the insertion washer 1D is pushed out to the fastened object X side when the tightening is completed. Due to the repulsive force on the insertion nut 3 due to this elastic force, the effect of preventing loosening against vibration and impact is further improved.
　以上のような本第４実施形態によれば、第２実施形態の効果に加えて、以下のような効果を奏する。
１．各ワッシャーピース６を同一形状に構成するため、製造コストを低減し、作業効率を向上することができる。
２．ナット係合部１４を周方向に連続的に構成するため、緩み止め効果を向上することができる。
３．嵌合凹部１７と嵌合凸部１８とを係止することで、厚さが薄く、簡単な構造でありながら緩み止め効果の高いワッシャーを提供できる。 According to the fourth embodiment as described above, the following effects can be obtained in addition to the effects of the second embodiment.
1. Since each washer piece 6 is configured in the same shape, the manufacturing cost can be reduced and the working efficiency can be improved.
2. Since the nut engaging part 14 is comprised continuously in the circumferential direction, the locking effect can be improved.
3. By locking the fitting concave portion 17 and the fitting convex portion 18, it is possible to provide a washer that is thin and has a simple structure but a high locking effect.
　なお、本発明に係る差込ワッシャーは、前述した各実施形態に限定されるものではなく、適宜変更することができる。 Note that the plug washer according to the present invention is not limited to the above-described embodiments, and can be changed as appropriate.
　例えば、上述した各実施形態では、外形が略円形の差込ワッシャー１Ａ，１Ｂ，１Ｃ，１Ｄについて説明したが、この構成に限られるものではなく、四角形等の差込ワッシャーであってもよい。 For example, in each of the above-described embodiments, the insertion washer 1A, 1B, 1C, 1D having a substantially circular outer shape has been described. However, the present invention is not limited to this configuration, and an insertion washer such as a square may be used.
