以下、本発明を具体化した一実施形態の座金を図1〜図6を参照して説明する。
図1に示すように、座金10は、円盤状に形成されている。座金10の表側面10aの周縁部には、リング状の突条12が形成されている。突条12は、規制突部の一例である。図2、図3に示すように座金10の突条12で囲まれた表側面10aには、裏側面10bまで貫通した透孔14及びボルト挿通孔16が形成されている。前記表側面10aはボルト出口側面の一例である。また、裏側面10bは、ボルト挿入側面の一例である。
Hereinafter, a washer according to an embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the washer 10 is formed in a disk shape. A ring-shaped protrusion 12 is formed on the peripheral edge of the front side surface 10 a of the washer 10. The protrusion 12 is an example of a restriction protrusion. As shown in FIGS. 2 and 3, the front side surface 10a surrounded by the ridges 12 of the washer 10 is formed with a through hole 14 and a bolt insertion hole 16 penetrating to the back side surface 10b. The front side surface 10a is an example of a bolt outlet side surface. The back side surface 10b is an example of a bolt insertion side surface.

図2に示すように透孔14は、その中心軸が座金10の軸心Oと同軸となるようにして穿設されている。透孔14は、ボルト30の雄ネジ部34の山径以下の径を有する。
また、図2に示すようにボルト挿通孔16は、軸心Oからオフセットした中心軸O1を有するように穿設されるとともに、透孔14と一部が重なるように配置されている。
As shown in FIG. 2, the through hole 14 is drilled so that the central axis thereof is coaxial with the axis O of the washer 10. The through hole 14 has a diameter equal to or smaller than the mountain diameter of the male threaded portion 34 of the bolt 30.
Further, as shown in FIG. 2, the bolt insertion hole 16 is formed so as to have a central axis O <b> 1 that is offset from the axial center O, and is disposed so as to partially overlap the through-hole 14.

ボルト挿通孔16の裏側面10bの開口16aはボルト挿入側開口に相当する。また、ボルト挿通孔16の表側面10aの開口16bはボルト出口開口に相当する。透孔14とボルト挿通孔16間には連通部20が設けられている。連通部20は、ボルト30の雄ネジ部34の山径以下の間隔を有する。   The opening 16a in the back side surface 10b of the bolt insertion hole 16 corresponds to the bolt insertion side opening. Further, the opening 16b on the front side surface 10a of the bolt insertion hole 16 corresponds to a bolt outlet opening. A communication portion 20 is provided between the through hole 14 and the bolt insertion hole 16. The communication part 20 has a distance equal to or smaller than the mountain diameter of the male thread part 34 of the bolt 30.

図5に示すようにボルト挿通孔16に螺合するボルト30は、ボルトヘッド32、雄ネジ部34及び雄ネジ部34をボルトヘッド32に連結するとともに雄ネジ部34の山径よりも小径の小径部36を有する。   As shown in FIG. 5, the bolt 30 screwed into the bolt insertion hole 16 connects the bolt head 32, the male screw portion 34, and the male screw portion 34 to the bolt head 32 and has a smaller diameter than the mountain diameter of the male screw portion 34. A small diameter portion 36 is provided.

ボルト挿通孔16の雌ネジ部18は、ボルト30の雄ネジ部34と螺合するネジ径及びネジピッチを有する。この結果、ボルト30の雄ネジ部34をボルト挿通孔16から通過させることができ、通過させると、小径部36は、雌ネジ部18の谷径以下の間隔を有する連通部20を介して同じく雌ネジ部18の谷径以下の径を有する透孔14に移動可能である。   The female screw portion 18 of the bolt insertion hole 16 has a screw diameter and a screw pitch to be screwed with the male screw portion 34 of the bolt 30. As a result, the male threaded portion 34 of the bolt 30 can be passed through the bolt insertion hole 16, and when it is passed, the small-diameter portion 36 is similarly connected via the communicating portion 20 having a gap equal to or less than the valley diameter of the female threaded portion 18. It can move to the through-hole 14 having a diameter equal to or smaller than the valley diameter of the female screw portion 18.

なお、図5に示すボルト30は、ボルトヘッド32に六角穴を有するが、この形式に限定するものではなく、例えば、外形が六角を有するボルト(六角ボルト)であってもよい。   In addition, although the volt | bolt 30 shown in FIG. 5 has a hexagon socket in the bolt head 32, it is not limited to this form, For example, the volt | bolt (hexagon bolt) which an outer shape has a hexagon may be sufficient.

また、図1、図2に示すように、ボルト挿通孔16の開口16bの周縁には、面取り部17が形成されている。ボルト30の雄ネジ部34は、面取り部17にガイドされて、雌ネジ部18から凹部19側へ通過可能であるとともに、雌ネジ部18に対して螺入可能である。また表側面10a側の透孔14の開口には、面取り部15が形成されている。図1に示すように面取り部15は、連通部20まで延出されている。透孔14の面取り部15は、ボルト挿通孔16の面取り部17よりも深く形成されている。   As shown in FIGS. 1 and 2, a chamfered portion 17 is formed on the periphery of the opening 16 b of the bolt insertion hole 16. The male screw portion 34 of the bolt 30 is guided by the chamfered portion 17, can pass from the female screw portion 18 to the concave portion 19 side, and can be screwed into the female screw portion 18. A chamfered portion 15 is formed in the opening of the through hole 14 on the front side surface 10a side. As shown in FIG. 1, the chamfered portion 15 extends to the communicating portion 20. The chamfered portion 15 of the through hole 14 is formed deeper than the chamfered portion 17 of the bolt insertion hole 16.

(実施形態の作用)
さて、上記のように構成された座金10の作用を図4〜図6を参照して説明する。
図4は、ボルト30により、扉部材40に対して、コ字状に形成された把手50の各端部が締結された状態を示している。本実施形態では、把手50の各端部の断面形状は、座金10の突条12で囲まれる凹部19の断面形状と相似形状に形成されており、前記凹部19内に嵌合可能に形成されている。把手50は、被締結部材の一例である。
(Operation of the embodiment)
Now, the operation of the washer 10 configured as described above will be described with reference to FIGS.
FIG. 4 shows a state in which each end portion of the handle 50 formed in a U shape is fastened to the door member 40 by the bolt 30. In the present embodiment, the cross-sectional shape of each end of the handle 50 is formed to be similar to the cross-sectional shape of the recess 19 surrounded by the ridge 12 of the washer 10, and is formed so as to be able to fit in the recess 19. ing. The handle 50 is an example of a member to be fastened.

把手50の端部52は、座金10の突条12で囲まれる凹部19内に嵌合された状態で、扉部材40の裏面(図4では下面)から扉部材40及び座金10を貫通したボルト30の雄ネジ部34にて締結されている。この締結により、把手50の各端面は、座金10の表側面10aに当接されている。   The end 52 of the handle 50 is a bolt that penetrates the door member 40 and the washer 10 from the back surface (the lower surface in FIG. 4) of the door member 40 in a state of being fitted in the recess 19 surrounded by the protrusion 12 of the washer 10. It is fastened by 30 male screw portions 34. By this fastening, each end surface of the handle 50 is in contact with the front side surface 10 a of the washer 10.

この把手50を扉部材40に取付けする場合、図5に示すように、扉部材40の裏面側から扉部材40の貫通孔42にボルト30を挿通するとともに、座金10のボルト挿通孔16に対してボルト30の雄ネジ部34を螺合する。そして、ボルト30の雄ネジ部34をボルト挿通孔16から通過させる。ボルト挿通孔16から雄ネジ部34を通過させると、小径部36がボルト挿通孔16に挿入された状態となるため、この状態で、図6に示すように、座金10を移動させて小径部36を連通部20から透孔14内に位置させるようにする。この状態で、把手50の端面に設けられた雌ネジ孔に対してボルト30を螺合する。この場合、把手50の端部端面に対するボルト30の螺合が進行すると、把手50の端部が突条12に規制された状態で凹部19内に嵌合されて扉部材40に対して締結される。   When the handle 50 is attached to the door member 40, as shown in FIG. 5, the bolt 30 is inserted into the through hole 42 of the door member 40 from the back surface side of the door member 40 and to the bolt insertion hole 16 of the washer 10. Then, the male thread portion 34 of the bolt 30 is screwed together. Then, the male screw portion 34 of the bolt 30 is passed through the bolt insertion hole 16. When the male screw part 34 is passed through the bolt insertion hole 16, the small diameter part 36 is inserted into the bolt insertion hole 16, and as shown in FIG. 6, the washer 10 is moved in this state to move the small diameter part. 36 is positioned in the through hole 14 from the communication portion 20. In this state, the bolt 30 is screwed into the female screw hole provided on the end face of the handle 50. In this case, when the screw 30 is engaged with the end face of the end of the handle 50, the end of the handle 50 is fitted into the recess 19 in a state where the end of the handle 50 is regulated by the protrusion 12, and is fastened to the door member 40. The

<ボルト30が緩んだ場合>
また、扉部材40に対するボルト30による把手50の締結後において、ボルト30の締結が緩むことがある。例えば、扉部材40の開閉時における振動、或いは、周辺環境から長期間に亘って付与される振動等によってボルトの締結の緩みが生ずる。
<When bolt 30 is loose>
In addition, the fastening of the bolt 30 may be loosened after the handle 50 is fastened to the door member 40 by the bolt 30. For example, the bolts are loosened due to vibrations when the door member 40 is opened or closed, or vibrations applied over a long period of time from the surrounding environment.

前記ボルト30の締結の緩みがあっても、把手50の端部が凹部19内に嵌合されている場合には、ボルト挿通孔16の雌ネジ部18と、把手50の雌ネジ孔は同軸にはなくずれていることから、ボルト30がボルト挿通孔16の雌ネジ部18から抜け出ることがないとともに透孔14から抜けでることもない。   Even if the bolt 30 is loosened, if the end of the handle 50 is fitted in the recess 19, the female screw portion 18 of the bolt insertion hole 16 and the female screw hole of the handle 50 are coaxial. Therefore, the bolt 30 does not come out of the female screw portion 18 of the bolt insertion hole 16 and does not come out of the through hole 14.

前記ボルト30の締結の緩みにより、ボルト30が把手50の端面の雌ネジ孔から抜け出た場合、ボルト30の小径部36が透孔14またはボルト挿通孔16または連通部20のいずれかの位置に挿通された状態となる。   When the bolt 30 is pulled out of the female screw hole on the end face of the handle 50 due to loose fastening of the bolt 30, the small-diameter portion 36 of the bolt 30 is positioned at any position of the through hole 14, the bolt insertion hole 16, or the communication portion 20. It will be inserted.

以下では、扉部材40の表面(把手50を取り付けている面)が上を向いている場合、上方とは直交する横を向いている場合について説明する。なお、把手50の扉部材40の表面が下を向いている場合は、ボルト30の雄ネジ部34が重力方向の下向きになり、ボルト30のボルトヘッド32が、扉部材40の裏面に係止する。このため、この場合は、扉部材40の表面(把手50を取り付けている面)が上を向いている場合よりもボルト30が更に扉部材40の貫通孔42から抜け出にくくなることは自明であるため説明を省略する。   Below, the case where the surface (surface to which the handle 50 is attached) of the door member 40 is facing upward, and the side that is orthogonal to the upper side will be described. When the surface of the door member 40 of the handle 50 faces downward, the male screw portion 34 of the bolt 30 faces downward in the gravity direction, and the bolt head 32 of the bolt 30 is locked to the back surface of the door member 40. To do. For this reason, in this case, it is obvious that the bolt 30 is more difficult to come out of the through hole 42 of the door member 40 than when the surface of the door member 40 (the surface to which the handle 50 is attached) is facing upward. Therefore, explanation is omitted.

<1.扉部材40の表面(把手50を取り付けている面)が上を向いている場合>
この場合、ボルト30が重力方向に引っ張られるため、ボルトヘッド32が下向きになるとともに、ボルト30の雄ネジ部34は、透孔14の面取り部15、または、連通部20の面取り部15に係合する。なお、振動等により雄ネジ部34がボルト挿通孔16に移動しようとしても、面取り部15の方が、ボルト挿通孔16の面取り部17よりも面取りを深く形成しているため、雄ネジ部34を面取り部15の方に誘うことになる。このため、ボルト30が、ボルト挿通孔16側に移動することが抑制されるため、ボルト挿通孔16からのボルト30の抜けを抑制する。
<1. When the surface of the door member 40 (the surface to which the handle 50 is attached) is facing upward>
In this case, since the bolt 30 is pulled in the direction of gravity, the bolt head 32 faces downward, and the male screw portion 34 of the bolt 30 is engaged with the chamfered portion 15 of the through hole 14 or the chamfered portion 15 of the communicating portion 20. Match. Even if the male screw portion 34 tries to move to the bolt insertion hole 16 due to vibration or the like, the chamfered portion 15 is deeper than the chamfered portion 17 of the bolt insertion hole 16, so the male screw portion 34. Will be invited to the chamfer 15. For this reason, since it is suppressed that the volt | bolt 30 moves to the volt | bolt penetration hole 16 side, the detachment | leave of the volt | bolt 30 from the bolt penetration hole 16 is suppressed.

<2.扉部材40の表面(把手50を取り付けている面)が横を向いている場合>
この場合、例えば、図6に示すようにボルト30は、貫通孔42が許容する範囲で、横方向に向く姿勢か、或いは、ボルトヘッド32が若干下向き、或いは若干上向きの姿勢となる。この場合、座金10は、ボルト30及び把手50による拘束が解除されているため、振動等により、自由に小径部36の周りで回転可能となる。
<2. When the surface of the door member 40 (the surface to which the handle 50 is attached) faces sideways>
In this case, for example, as shown in FIG. 6, the bolt 30 has a lateral orientation or a bolt head 32 slightly downward or slightly upward as long as the through hole 42 allows. In this case, since the restraint by the bolt 30 and the handle 50 is released, the washer 10 can freely rotate around the small diameter portion 36 due to vibration or the like.

座金10の回転位置によって、ボルト30の雄ネジ部34が、透孔14、または、連通部20の面取り部15に係合することになる。
仮に、座金10の回転位置によって、雄ネジ部34が連通部20から遠位のときは、ボルト挿通孔16からのボルト30の抜けを抑制する。
Depending on the rotational position of the washer 10, the male screw portion 34 of the bolt 30 is engaged with the through hole 14 or the chamfered portion 15 of the communication portion 20.
If the male screw portion 34 is distal from the communication portion 20 due to the rotational position of the washer 10, the bolt 30 is prevented from coming off from the bolt insertion hole 16.

また、仮に座金10の回転位置によって、雄ネジ部34が連通部20に近位のときは、雄ネジ部34が、面取り部17にガイドされない限り、ボルト挿通孔16からボルト30が抜け出ることがない。特に、ボルトヘッド32が若干下向き、或いは若干上向きの姿勢の場合は、ボルト30がボルト挿通孔16に対して斜めとなるため、極めてボルト挿通孔16に螺入しがたいものとなる。   Further, if the male screw portion 34 is proximal to the communication portion 20 due to the rotational position of the washer 10, the bolt 30 may come out of the bolt insertion hole 16 unless the male screw portion 34 is guided by the chamfered portion 17. Absent. In particular, when the bolt head 32 is in a slightly downward or slightly upward posture, the bolt 30 is inclined with respect to the bolt insertion hole 16, so that it is extremely difficult to screw into the bolt insertion hole 16.

従って、この場合においても、座金10によって、ボルト30の抜け出しが困難となる。
なお、扉部材40が、斜め下方向き、或いは斜め上方向きの場合は、上記の作用が組み合わされるため、いずれにしても、ボルト30の抜けを抑制できる。
Accordingly, even in this case, the bolt 30 is difficult to be pulled out by the washer 10.
In addition, since the said effect | action is combined when the door member 40 is diagonally downward or diagonally upward, it can suppress the detachment | leave of the volt | bolt 30 in any case.

本実施形態によれば、下記の特徴がある。
(1)本実施形態の座金10は、裏側面10b(ボルト挿入側面)には開口16a(ボルト挿入側開口)を備えるとともに表側面10a(ボルト出口側面)には開口16b(ボルト出口開口)を有するボルト挿通孔16を備える。また、ボルト挿通孔16は、内周面に雌ネジ部18が形成されている。この結果、本実施形態によれば、簡単な構成で、ボルトの脱落が抑制できる。
The present embodiment has the following features.
(1) The washer 10 of the present embodiment includes an opening 16a (bolt insertion side opening) on the back side surface 10b (bolt insertion side surface) and an opening 16b (bolt outlet opening) on the front side surface 10a (bolt outlet side surface). A bolt insertion hole 16 is provided. The bolt insertion hole 16 has a female screw portion 18 formed on the inner peripheral surface. As a result, according to the present embodiment, the bolt can be prevented from falling off with a simple configuration.

(2)本実施形態の座金10は、ボルト挿通孔16に対してオフセットした透孔14と、前記透孔14とボルト挿通孔16を連通する連通部20を備えている。また、連通部20及び透孔14は、ボルト挿通孔16の雌ネジ部18の谷径(すなわち、ボルト30の雄ネジ部34の山径)以下の径を有する。   (2) The washer 10 of this embodiment includes a through hole 14 that is offset with respect to the bolt insertion hole 16 and a communication portion 20 that communicates the through hole 14 and the bolt insertion hole 16. Further, the communication portion 20 and the through hole 14 have a diameter equal to or less than the root diameter of the female screw portion 18 of the bolt insertion hole 16 (that is, the mountain diameter of the male screw portion 34 of the bolt 30).

この結果、本実施形態によれば、連通部20及び透孔14が、ボルト挿通孔16の雌ネジ部18の谷径以下であるため、ボルト挿通孔16に螺合するボルトを透孔14または連通部20で、抜け出しを抑制することができる。   As a result, according to the present embodiment, since the communication portion 20 and the through hole 14 are equal to or less than the valley diameter of the female screw portion 18 of the bolt insertion hole 16, the bolt to be screwed into the bolt insertion hole 16 is inserted into the through hole 14 or The communication part 20 can suppress the escape.

(3)本実施形態の座金10の透孔14の中心軸は、座金10の軸心Oと同軸に配置されている。この結果、ボルト締結時には、座金10をボルトの軸心と同軸にすることができる。   (3) The central axis of the through hole 14 of the washer 10 of this embodiment is arranged coaxially with the axis O of the washer 10. As a result, at the time of bolt fastening, the washer 10 can be coaxial with the axis of the bolt.

(4)本実施形態の座金10の透孔14は、ボルト挿通孔16と一部が重なるように配置されている。また、連通部20は透孔14とボルト挿通孔16の間に形成されている。この結果、本実施形態によれば、ボルト挿通孔16と一部が重なるように配置した分だけ、座金10の大きさを小さくできる。   (4) The through hole 14 of the washer 10 of the present embodiment is disposed so as to partially overlap the bolt insertion hole 16. The communication part 20 is formed between the through hole 14 and the bolt insertion hole 16. As a result, according to the present embodiment, the size of the washer 10 can be reduced by an amount that is disposed so as to partially overlap the bolt insertion hole 16.

(5)本実施形態の座金10は、ボルト挿通孔16の開口16b(ボルト出口開口)及び透孔14の表側面10a(ボルト出口側面)側の開口には、それぞれ面取り部17、15が形成されている。また、透孔14の面取り部15は、ボルト挿通孔16の面取り部17よりも深く形成されている。   (5) In the washer 10 of this embodiment, chamfered portions 17 and 15 are formed in the opening 16b (bolt outlet opening) of the bolt insertion hole 16 and the opening on the front side surface 10a (bolt outlet side surface) side of the through hole 14, respectively. Has been. Further, the chamfered portion 15 of the through hole 14 is formed deeper than the chamfered portion 17 of the bolt insertion hole 16.

この結果、雄ネジ部を面取り部の方に誘うことができ、ボルトがボルト挿通孔16側に移動することが抑制されるため、ボルト挿通孔からのボルトの抜けを抑制できる。
(6)本実施形態の座金10は、表側面10a(ボルト出口側面)には、透孔14に挿入されたボルトにより表側面10a(ボルト出口側面)に当接して締結される把手50(被締結部材)を規制する突条12(規制突部)が形成されている。この結果、本実施形態によれば、ボルトの締結の若干の緩みがあった場合、被締結部材の締結の緩みによる動きを規制突部により規制することができる。
As a result, the male screw portion can be invited toward the chamfered portion and the bolt is suppressed from moving to the bolt insertion hole 16 side, so that the bolt can be prevented from coming off from the bolt insertion hole.
(6) The washer 10 of the present embodiment has a handle 50 (covered) that is fastened to the front side surface 10a (bolt outlet side surface) by abutting against the front side surface 10a (bolt outlet side surface) with a bolt inserted into the through hole 14. A protrusion 12 (restriction protrusion) that restricts the fastening member) is formed. As a result, according to this embodiment, when there is a slight loosening of the bolt, the movement due to the loosening of the fastened member can be restricted by the restriction protrusion.

なお、本発明は前記実施形態に限定されるものではなく、下記のように構成してもよい。
・前記実施形態では、透孔14を設けたが、透孔14を省略してもよい。この場合、貫通孔42の中心軸O1は、座金10の軸心と同軸に配置してもよい。このようにした場合、例えば、把手50から抜け出たボルト30の雄ネジ部34が、ボルト挿通孔16に合致しない限り、ボルト30が、座金10から抜け出ることがない。ボルト30の雄ネジ部34が、ボルト挿通孔16の雌ネジ部18に対して合致するまでの期間及び合致した後からボルト挿通孔16を抜け出るまでの期間は、ボルト挿通孔16が、扉部材40から抜け出せない期間となる。
In addition, this invention is not limited to the said embodiment, You may comprise as follows.
In the embodiment, the through hole 14 is provided, but the through hole 14 may be omitted. In this case, the central axis O <b> 1 of the through hole 42 may be arranged coaxially with the axial center of the washer 10. In this case, for example, the bolt 30 does not come out of the washer 10 unless the male thread portion 34 of the bolt 30 that has come out of the handle 50 matches the bolt insertion hole 16. During the period until the male threaded portion 34 of the bolt 30 matches the female threaded portion 18 of the bolt insertion hole 16 and the period after the matching until the male threaded portion 34 exits the bolt insertion hole 16, the bolt insertion hole 16 is connected to the door member. It is a period during which it is not possible to escape from 40.

なお、雌ネジ部18が形成されていない従来の座金の場合は、前述したボルト挿通孔16の雌ネジ部18に対して合致するまでの期間及び合致した後からボルト挿通孔16を螺退しながら抜け出るまでの期間はない。   In the case of a conventional washer in which the female screw portion 18 is not formed, the bolt insertion hole 16 is screwed out after the period until the bolt insertion hole 16 is matched with the female screw portion 18 and after the matching. However, there is no time to exit.

このため、従来は、この実施形態に比較すると、把手50との螺合が解除されたボルトは、扉部材40から脱落する時期が早期となる。一方、この実施形態によればボルトの脱落時点を遅くすることができ、そのボルト脱落時点が遅くなるだけ、ボルトの緩んだことを知らせる期間が長くできる。例えば、ボルト30と把手50との螺合が解除されると、扉部材40の開閉等による振動、或いは、周辺環境の振動が付与されれば、その振動により座金10が振動する。このため、座金10が扉部材40、把手50等に当たるときの音等により、ボルトの緩みがあることを報知することも期待できる。   For this reason, conventionally, when compared with this embodiment, the bolt that has been unscrewed from the handle 50 is removed from the door member 40 earlier. On the other hand, according to this embodiment, the drop-off time of the bolt can be delayed, and the period for notifying that the bolt has been loosened can be lengthened as the bolt drop-off time is delayed. For example, when the screwing of the bolt 30 and the handle 50 is released, the washer 10 vibrates due to the vibration caused by the opening and closing of the door member 40 or the vibration of the surrounding environment. For this reason, it can be expected that the bolt is loosely notified by a sound or the like when the washer 10 hits the door member 40, the handle 50, or the like.

・前記実施形態において、突部(突条12等)を省略してもよい。
・前記実施形態において、前記表側面10aをボルト出口側面とし、裏側面10bをボルト挿入側面としたが、逆の関係であってもよい。
-In the said embodiment, you may abbreviate | omit a protrusion (projection 12 etc.).
In the embodiment, the front side surface 10a is a bolt outlet side surface and the back side surface 10b is a bolt insertion side surface, but the reverse relationship may be used.

・前記実施形態では、座金10を円盤状に形成したが、これは一例であってその形状は限定されるものではない。
例えば、図7に示すように、座金10を四角板状に形成するとともに、表側面10aの長手方向の両端に規制突部としての突部13を形成してもよい。なお、図7に示す構成において、前記実施形態と同一または相当する構成については、同一符号を付して、その説明を省略する。図7に示す例では、把手50に代えて六角ナット60を被締結部材としている。このようにしても、ボルト30と六角ナット60により、図示しない支持部材に対して、図示しない被支持部材を取付固定することが可能であり、この場合でもボルト挿通孔16からのボルト30の抜けを抑制できる。なお、図7では、被支持部材、及び支持部材は説明の便宜上、省略されている。
In the embodiment, the washer 10 is formed in a disc shape, but this is an example and the shape is not limited.
For example, as shown in FIG. 7, the washer 10 may be formed in a square plate shape, and the protrusions 13 as the restriction protrusions may be formed at both ends of the front side surface 10 a in the longitudinal direction. In the configuration shown in FIG. 7, the same or corresponding components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the example shown in FIG. 7, a hexagon nut 60 is used as a fastened member instead of the handle 50. Even in such a case, it is possible to attach and fix a supported member (not shown) to a supporting member (not shown) with the bolt 30 and the hexagon nut 60. Even in this case, the bolt 30 can be removed from the bolt insertion hole 16. Can be suppressed. In FIG. 7, the supported member and the supporting member are omitted for convenience of explanation.

・前記実施形態では、透孔14の一部がボルト挿通孔16と重なるように配置したが、重ならないように離間して配置してもよい。この場合、連通部は、両者を繋ぐように設ければよい。また、この場合、前記連通部は、ボルトの雄ネジの山径よりも小径の小径部36を移動可能な幅に形成すればよい。   In the above embodiment, the through hole 14 is disposed so that a part of the through hole 14 overlaps with the bolt insertion hole 16, but may be disposed apart so as not to overlap. In this case, the communication unit may be provided so as to connect the two. In this case, the communicating portion may be formed to have a width that allows the small-diameter portion 36 smaller in diameter than the mountain diameter of the male screw of the bolt to be moved.

・前記実施形態において、透孔14とボルト挿通孔16のそれぞれに面取り部15及び面取り部17を設けたが、省略してもよい。或いは、面取り部15と面取り部17の面取り深さを同じとしてもよい。   In the embodiment, the chamfered portion 15 and the chamfered portion 17 are provided in each of the through hole 14 and the bolt insertion hole 16, but may be omitted. Alternatively, the chamfering depth of the chamfered portion 15 and the chamfered portion 17 may be the same.

・前記実施形態では、ボルト30を六角穴ボルトとしたが、六角穴ボルト以外の多角穴等の穴ボルト、または、六角ボルト以外のボルトであってもよい。   In the embodiment, the bolt 30 is a hexagon socket bolt, but a bolt such as a polygonal hole other than the hexagon socket bolt or a bolt other than the hexagon bolt may be used.
