The frame main body 12 is formed with a locking projection 17, a regulation projection 18, and a screw hole 19 to form the instrument mounting frame 11.

次に、配線器具Ｈを保持する器具保持枠２０について説明する。
図１に示すように、器具保持枠２０は、縦長の四角枠状に形成されるとともに、器具保持枠２０の内側には、縦長四角形状の保持孔２１が形成されている。なお、器具保持枠２０の長辺方向への長さＭ１は、壁孔Ｗａの長辺方向への長さＮ１より長くなっている。一方、器具保持枠２０の短辺方向への長さＭ２は、壁孔Ｗａの短辺方向への長さＮ２より短くなっている。器具保持枠２０の上下両部には、横長の挿通孔２２が器具保持枠２０を厚み方向に貫通して形成されている。 Next, the appliance holding frame 20 that holds the wiring appliance H will be described.
As shown in FIG. 1, the device holding frame 20 is formed in a vertically long rectangular frame shape, and a vertically long rectangular holding hole 21 is formed inside the device holding frame 20. Note that the length M1 of the instrument holding frame 20 in the long side direction is longer than the length N1 of the wall hole Wa in the long side direction. On the other hand, the length M2 of the instrument holding frame 20 in the short side direction is shorter than the length N2 of the wall hole Wa in the short side direction. A horizontally long insertion hole 22 is formed in both the upper and lower portions of the instrument holding frame 20 so as to penetrate the instrument holding frame 20 in the thickness direction.

次に、器具取付枠１１及び器具保持枠２０を用いて配線器具Ｈを壁材Ｗに設置する方法について説明する。
まず、図５（ａ）及び（ｂ）に示すように、壁材Ｗの表面において、壁孔Ｗａを形成する位置に、四つの罫書用突起１８ｂが壁孔Ｗａの四つの角部の内側に位置するように器具取付枠１１を配置し、器具取付枠１１を壁材Ｗの表面に押し付けて四つの罫書用突起１８ｂを壁材Ｗの表面に食い込ませる。図５（ｃ）に示すように、器具取付枠１１を壁材Ｗから取り外すと、四つの罫書用突起１８ｂが食い込んだ位置それぞれに突起跡Ｐが形成される。そして、四つの突起跡Ｐを直線状の罫書線Ｑで結ぶと、壁孔Ｗａの外形線が壁材Ｗに罫書かれる。その後、罫書線Ｑに沿って壁材Ｗを切除することにより壁材Ｗに壁孔Ｗａが穿設される。 Next, a method of installing the wiring device H on the wall material W using the device mounting frame 11 and the device holding frame 20 will be described.
First, as shown in FIGS. 5A and 5B, on the surface of the wall material W, the four ruled line projections 18b are located inside the four corners of the wall hole Wa at the position where the wall hole Wa is formed. The instrument mounting frame 11 is disposed so as to be positioned, and the instrument mounting frame 11 is pressed against the surface of the wall material W to cause the four ruled line projections 18b to bite into the surface of the wall material W. As shown in FIG. 5C, when the instrument mounting frame 11 is removed from the wall material W, projection marks P are formed at the respective positions where the four ruled line projections 18b are bitten. Then, when the four protrusion traces P are connected by a linear ruled line Q, the outline of the wall hole Wa is marked on the wall material W. Thereafter, the wall material W is cut along the ruled line Q, so that a wall hole Wa is formed in the wall material W.

次に、図６に示すように、配線器具Ｈを器具保持枠２０の保持孔２１に保持させるとともに、器具保持枠２０の上側の挿通孔２２にビス２３を挿通する。そして、このビス２３を、器具取付枠１１の上側の螺入孔１９に挿入するとともに、ナットに螺入し、器具取付枠１１と器具保持枠２０を仮固定する。すると、器具取付枠１１と器具保持枠２０は、それぞれビス２３を回動軸として互いに回動自在に連結される。さらに、各配線器具ＨにケーブルＫを接続する。そして、器具保持枠２０を壁材Ｗの表側に配置しつつ、器具取付枠１１のみを壁孔Ｗａを通過させる。このとき、ビス２３を回動中心として器具取付枠１１を回動させ、壁孔Ｗａの開口縁を開口部１５内に位置させるようにし、器具取付枠１１を壁孔Ｗａを通過させる。すると、器具保持枠２０は、壁材Ｗの表側に配置されながら、器具取付枠１１のみが壁材Ｗの裏側に配置されるとともに、ビス２３により、器具取付枠１１は壁材Ｗの裏側に支持される。   Next, as shown in FIG. 6, the wiring device H is held in the holding hole 21 of the device holding frame 20, and the screw 23 is inserted into the insertion hole 22 on the upper side of the device holding frame 20. Then, the screw 23 is inserted into the screw hole 19 on the upper side of the instrument mounting frame 11 and is screwed into the nut to temporarily fix the instrument mounting frame 11 and the instrument holding frame 20. Then, the instrument mounting frame 11 and the instrument holding frame 20 are connected to each other so as to be rotatable about the screw 23 as a rotation axis. Further, a cable K is connected to each wiring device H. Then, while the instrument holding frame 20 is disposed on the front side of the wall material W, only the instrument mounting frame 11 is passed through the wall hole Wa. At this time, the instrument mounting frame 11 is rotated with the screw 23 as the center of rotation so that the opening edge of the wall hole Wa is positioned in the opening 15, and the instrument mounting frame 11 is passed through the wall hole Wa. Then, while the instrument holding frame 20 is arranged on the front side of the wall material W, only the instrument mounting frame 11 is arranged on the back side of the wall material W, and the instrument mounting frame 11 is placed on the back side of the wall material W by screws 23. Supported.

続いて、壁材Ｗの裏側で、器具取付枠１１の当接面１２ａを壁材Ｗの裏面に当接させるとともに、四つの規制突部１８を壁孔Ｗａ内に挿入する。図３に示すように、上側の一対の規制突部１８においては、右側の規制突部１８は、上面が壁孔Ｗａの上側面Ｗ１に当接するとともに、右側端が、上側面Ｗ１に隣り合う右側面Ｗ３に当接する。左側の規制突部１８は、上面が壁孔Ｗａの上側面Ｗ１に当接するとともに、左側端が、上側面Ｗ１に隣り合う左側面Ｗ４に当接する。   Subsequently, on the back side of the wall material W, the contact surface 12a of the instrument mounting frame 11 is brought into contact with the back surface of the wall material W, and the four restricting protrusions 18 are inserted into the wall holes Wa. As shown in FIG. 3, in the pair of upper restriction protrusions 18, the right restriction protrusion 18 has an upper surface that abuts on the upper side surface W <b> 1 of the wall hole Wa and a right end adjacent to the upper side surface W <b> 1. It contacts the right side W3. The upper surface of the left regulation protrusion 18 is in contact with the upper side surface W1 of the wall hole Wa, and the left end is in contact with the left side surface W4 adjacent to the upper side surface W1.

下側の一対の規制突部１８においては、右側の規制突部１８は、下面が壁孔Ｗａの下側面Ｗ２に当接支持されるとともに、右側端が、下側面Ｗ２に隣り合う右側面Ｗ３に当接する。左側の規制突部１８は、下面が壁孔Ｗａの下側面Ｗ２に当接支持されるとともに、左側端が、下側面Ｗ２に隣り合う左側面Ｗ４に当接する。   In the pair of lower restricting protrusions 18, the right restricting protrusion 18 is supported such that the lower surface is in contact with and supported by the lower side surface W2 of the wall hole Wa, and the right end is adjacent to the lower side surface W2. Abut. The left regulation protrusion 18 has a lower surface in contact with and supported by the lower side surface W2 of the wall hole Wa, and a left end in contact with the left side surface W4 adjacent to the lower side surface W2.

そして、四つの規制突部１８が壁孔Ｗａに挿入された状態では、下側の一対の規制突部１８が、壁孔Ｗａの下側面Ｗ２に支持されることにより、器具取付枠１１が壁材Ｗに位置決めされる。この位置決め状態では、器具取付枠１１の開口部１５が、壁孔Ｗａから壁材Ｗの表側に臨むとともに、螺入孔１９も壁孔Ｗａから壁材Ｗの表側に臨んでいる。   In the state where the four restricting protrusions 18 are inserted into the wall hole Wa, the pair of lower restricting protrusions 18 are supported by the lower side surface W2 of the wall hole Wa, so that the instrument mounting frame 11 is attached to the wall. Positioned on the material W. In this positioning state, the opening 15 of the instrument mounting frame 11 faces the front side of the wall material W from the wall hole Wa, and the screw hole 19 also faces the front side of the wall material W from the wall hole Wa.

さらに、図４に示すように、上側の係止突部１７の各爪片１７ａを、壁孔Ｗａの上側面Ｗ１に食い込ませて係止させるとともに、下側の係止突部１７の各爪片１７ａを、壁孔Ｗａの下側面Ｗ２に食い込ませて係止させる。すると、各爪片１７ａの係止により、器具取付枠１１が壁材Ｗの裏側へ落下することが規制される。   Further, as shown in FIG. 4, each claw piece 17a of the upper locking projection 17 is bitten into the upper side surface W1 of the wall hole Wa and locked, and each claw of the lower locking projection 17 is locked. The piece 17a is bitten into the lower surface W2 of the wall hole Wa to be locked. Then, the locking of each claw piece 17a restricts the instrument mounting frame 11 from falling to the back side of the wall material W.

続いて、図７に示すように、器具取付枠１１に対し、上側のナットに螺入されたビス２３をさらに螺入する。また、器具保持枠２０の下側の挿通孔２２に対し、ビス２３を挿通するとともに、そのビス２３を器具取付枠１１の下側の螺入孔１９のナットに螺入する。そして、両ビス２３を増締めすると、ビス２３のナットへの螺進に伴い器具保持枠２０が壁材Ｗに引寄せられるとともに、器具取付枠１１の両挟持片１３と、器具保持枠２０の上下両部との間に壁材Ｗが挟持される。ビス２３のナットへの螺入により、配線器具Ｈが壁材Ｗの表側に設置されることで、器具取付枠１１が壁材Ｗの裏側に設置される。このとき、枠本体１２の当接面１２ａが、壁材Ｗの裏面における壁孔Ｗａの周縁部に当接する。   Subsequently, as shown in FIG. 7, the screw 23 screwed into the upper nut is further screwed into the instrument mounting frame 11. Further, the screw 23 is inserted into the lower insertion hole 22 of the instrument holding frame 20, and the screw 23 is screwed into the nut of the lower screw hole 19 of the instrument mounting frame 11. When both the screws 23 are tightened, the instrument holding frame 20 is attracted to the wall material W as the screws 23 are screwed into the nuts, and both the holding pieces 13 of the instrument mounting frame 11 and the instrument holding frame 20 are A wall material W is sandwiched between the upper and lower portions. When the screw 23 is screwed into the nut, the wiring device H is installed on the front side of the wall material W, so that the device mounting frame 11 is installed on the back side of the wall material W. At this time, the contact surface 12 a of the frame body 12 contacts the peripheral edge of the wall hole Wa on the back surface of the wall material W.

次に、器具取付枠１１の作用について説明する。
枠本体１２に四つの規制突部１８が突設され、四つ規制突部１８を壁孔Ｗａに挿入すると、四つの規制突部１８が四つの内側面Ｗ１〜Ｗ４に当接する。このため、枠本体１２に対し、上下左右のいずれかの方向へ移動させる力が作用しても、規制突部１８がその移動方向の先にある内側面Ｗ１〜Ｗ４に当接し、枠本体１２の上下左右方向への移動が規制される。その結果、器具取付枠１１が、開口部１５及び螺入孔１９が壁材Ｗの表側に臨む位置で位置決めされるため、器具取付枠１１のナットに対するビス２３の螺入作業を容易に行うことができる。 Next, the operation of the instrument mounting frame 11 will be described.
Four restricting protrusions 18 project from the frame body 12 and when the four restricting protrusions 18 are inserted into the wall holes Wa, the four restricting protrusions 18 come into contact with the four inner side surfaces W1 to W4. For this reason, even if a force that moves the frame main body 12 in any of the up, down, left, and right directions is applied, the restricting protrusion 18 abuts on the inner side surfaces W1 to W4 that are ahead in the moving direction, and the frame main body 12 Movement in the vertical and horizontal directions is restricted. As a result, the instrument mounting frame 11 is positioned at a position where the opening 15 and the screw hole 19 face the front side of the wall material W, so that the screw 23 can be easily screwed into the nut of the instrument mounting frame 11. Can do.

上記実施形態によれば、以下のような効果を得ることができる。
（１）器具取付枠１１において、枠本体１２の前面に規制突部１８を突設した。そして、規制突部１８を壁孔Ｗａに挿入すると、規制突部１８が壁孔Ｗａの四つの内側面Ｗ１〜Ｗ４に当接して、器具取付枠１１の開口部１５が壁孔Ｗａに臨む位置に位置決めすることができる。したがって、規制突部１８を壁孔Ｗａに挿入するだけで、器具取付枠１１を位置決めすることができ、背景技術のように爪片を折り曲げる作業を必要とせずに器具取付枠１１の位置決め作業を簡単に行うことができる。 According to the above embodiment, the following effects can be obtained.
(1) In the instrument mounting frame 11, a restricting protrusion 18 is provided on the front surface of the frame body 12. When the restricting protrusion 18 is inserted into the wall hole Wa, the restricting protrusion 18 comes into contact with the four inner surfaces W1 to W4 of the wall hole Wa, and the opening 15 of the instrument mounting frame 11 faces the wall hole Wa. Can be positioned. Therefore, the instrument mounting frame 11 can be positioned simply by inserting the restricting protrusion 18 into the wall hole Wa, and the positioning operation of the instrument mounting frame 11 can be performed without the need to bend the claw pieces as in the background art. It can be done easily.

（２）枠本体１２の当接面１２ａを壁材Ｗの裏面に当接させた状態では、規制突部１８は壁孔Ｗａ内に位置し、壁材Ｗの表側に突出しないため、壁孔Ｗａ内で規制突部１８を曲げたり、折り取る必要がない。よって、当接面１２ａを壁材Ｗの裏面に当接させつつ規制突部１８を壁孔Ｗａに挿入するだけで、器具取付枠１１の位置決め作業が完了し、位置決め作業を簡単に行うことができる。   (2) In the state where the contact surface 12a of the frame main body 12 is in contact with the back surface of the wall material W, the restricting protrusion 18 is located in the wall hole Wa and does not protrude to the front side of the wall material W. There is no need to bend or break the regulating protrusion 18 in Wa. Therefore, the positioning operation of the instrument mounting frame 11 is completed and the positioning operation can be easily performed simply by inserting the regulating protrusion 18 into the wall hole Wa while the abutting surface 12a is abutting against the back surface of the wall material W. it can.

（３）規制突部１８は、枠本体１２に四つ突設されるとともに、各規制突部１８は、壁孔Ｗａの各角部の内側に配置される。そして、規制突部１８は、各角部を形成する隣り合う内側面に当接する。このため、四つの規制突部１８を、壁孔Ｗａの四つの内側面に当接させる構成としても、それら四つの規制突部１８は壁孔Ｗａの上側面Ｗ１と下側面Ｗ２寄りに配置することができ、四つの規制突部１８が壁孔Ｗａを大きく邪魔することがなく、規制突部１８が、配線器具Ｈ設置の妨げになることを防止することができる。   (3) Four restricting protrusions 18 are provided to protrude from the frame body 12, and each restricting protrusion 18 is disposed inside each corner of the wall hole Wa. And the control protrusion 18 is contact | abutted to the adjacent inner surface which forms each corner | angular part. For this reason, even if the four restricting protrusions 18 are configured to abut on the four inner surfaces of the wall hole Wa, the four restricting protrusions 18 are arranged closer to the upper side W1 and the lower side W2 of the wall hole Wa. The four restricting protrusions 18 do not greatly disturb the wall hole Wa, and the restricting protrusions 18 can be prevented from hindering the installation of the wiring device H.

（４）規制突部１８は、枠本体１２に四つ突設されるとともに、各規制突部１８は、壁孔Ｗａの各角部の内側に配置される。そして、規制突部１８は、各角部を形成する隣り合う内側面に当接する。このため、四つの規制突部１８を、枠本体１２の二つの挟持片１３に形成することができ、連結片１４に規制突部１８を形成しなくて済む。このため、連結片１４が、壁孔Ｗａ内に位置することがなく、壁孔Ｗａの短辺方向が器具取付枠１１によって狭められることを防止することができる。   (4) Four restriction protrusions 18 are provided to protrude from the frame body 12, and each restriction protrusion 18 is disposed inside each corner of the wall hole Wa. And the control protrusion 18 is contact | abutted to the adjacent inner surface which forms each corner | angular part. For this reason, the four restricting protrusions 18 can be formed on the two sandwiching pieces 13 of the frame body 12, and the restricting protrusions 18 need not be formed on the connecting piece 14. For this reason, the connecting piece 14 is not positioned in the wall hole Wa, and the short side direction of the wall hole Wa can be prevented from being narrowed by the instrument mounting frame 11.

（５）規制突部１８は、枠本体１２に四つ突設されるとともに、各規制突部１８は、壁孔Ｗａの各角部の内側に配置される。そして、規制突部１８は、各角部を形成する隣り合う内側面に当接する。このため、四つの規制突部１８を、枠本体１２の二つの挟持片１３に形成することができ、枠本体１２をコ字状に形成して右側方を開放させることができる。したがって、枠本体１２に四つの規制突部１８を形成しつつも、器具取付枠１１をコ字状に形成することが可能になり、器具取付枠１１を壁孔Ｗａを簡単に通過させることができ、器具取付枠１１を壁材Ｗの裏側に簡単に配置することができる。   (5) Four restricting protrusions 18 are provided to protrude from the frame body 12, and each restricting protrusion 18 is disposed inside each corner of the wall hole Wa. And the control protrusion 18 is contact | abutted to the adjacent inner surface which forms each corner | angular part. For this reason, the four restricting protrusions 18 can be formed on the two sandwiching pieces 13 of the frame main body 12, and the frame main body 12 can be formed in a U shape to open the right side. Therefore, it is possible to form the fixture mounting frame 11 in a U-shape while forming the four restricting protrusions 18 on the frame main body 12, and it is possible to easily pass the fixture mounting frame 11 through the wall hole Wa. The instrument mounting frame 11 can be easily arranged on the back side of the wall material W.

（６）枠本体１２には、係止突部１７が形成されるとともに、この係止突部１７は、壁孔Ｗａの上側面Ｗ１及び下側面Ｗ２に係止する。このため、ビス２３を器具取付枠１１の螺入孔１９に螺入する際、器具取付枠１１に壁材Ｗの裏側へ押す力が作用しても、係止突部１７の係止により器具取付枠１１の壁材Ｗの裏側への移動を規制することができる。したがって、ビス２３の螺入作業時に、器具取付枠１１を手で押さえて壁材Ｗの裏側へ移動することを規制する必要がなく、ビス２３の螺入作業を簡単に行うことができる。   (6) A locking projection 17 is formed on the frame body 12 and the locking projection 17 is locked to the upper side W1 and the lower side W2 of the wall hole Wa. For this reason, when the screw 23 is screwed into the screw hole 19 of the instrument mounting frame 11, even if a force pushing the instrument mounting frame 11 to the back side of the wall material W acts on the instrument mounting frame 11, the locking projection 17 locks the instrument. The movement of the mounting frame 11 to the back side of the wall material W can be restricted. Therefore, it is not necessary to restrict the movement of the screw 23 to the back side of the wall material W by manually pressing the tool mounting frame 11 during the screwing operation of the screw 23, and the screwing operation of the screw 23 can be easily performed.

（７）係止突部１７は、枠本体１２に四つ突設されるとともに、各係止突部１７は、枠本体１２の短辺方向（左右方向）における各規制突部１８の内側に配置される。このため、四つの係止突部１７を、壁孔Ｗａの内側面に係止させる構成としても、それら四つの係止突部１７は壁孔Ｗａの上側面Ｗ１と下側面Ｗ２寄りに配置することができ、四つの係止突部１７が壁孔Ｗａを大きく邪魔することがなく、係止突部１７が、配線器具Ｈ設置の妨げになることを防止することができる。   (7) Four locking protrusions 17 are provided on the frame main body 12, and the locking protrusions 17 are provided inside the restricting protrusions 18 in the short side direction (left-right direction) of the frame main body 12. Be placed. For this reason, even if the four locking projections 17 are configured to be locked to the inner side surface of the wall hole Wa, the four locking projections 17 are arranged closer to the upper side surface W1 and the lower side surface W2 of the wall hole Wa. Therefore, the four locking projections 17 do not greatly disturb the wall hole Wa, and the locking projections 17 can be prevented from hindering the installation of the wiring device H.

（８）係止突部１７は、枠本体１２に四つ突設されるとともに、各係止突部１７は、枠本体１２の短辺方向（左右方向）における各規制突部１８の内側に配置される。このため、四つの係止突部１７を、枠本体１２の二つの挟持片１３に形成することができ、連結片１４に係止突部１７を形成しなくて済む。このため、連結片１４が、壁孔Ｗａ内に位置することがなく、壁孔Ｗａの短辺方向が器具取付枠１１によって狭められることを防止することができる。   (8) Four locking protrusions 17 are provided on the frame main body 12, and the locking protrusions 17 are provided inside the restricting protrusions 18 in the short side direction (left-right direction) of the frame main body 12. Be placed. For this reason, the four locking projections 17 can be formed on the two sandwiching pieces 13 of the frame main body 12, and the locking projections 17 do not have to be formed on the connecting piece 14. For this reason, the connecting piece 14 is not positioned in the wall hole Wa, and the short side direction of the wall hole Wa can be prevented from being narrowed by the instrument mounting frame 11.

（９）係止突部１７は、枠本体１２に四つ突設されるとともに、各係止突部１７は、枠本体１２の短辺方向（左右方向）における各規制突部１８の内側に配置される。このため、四つの係止突部１７を、枠本体１２の二つの挟持片１３に形成することができ、枠本体１２をコ字状に形成して右側方を開放させることができる。したがって、枠本体１２に四つの係止突部１７を形成しつつも、器具取付枠１１をコ字状に形成することが可能になり、器具取付枠１１を壁孔Ｗａを簡単に通過させることができ、器具取付枠１１を壁材Ｗの裏側に簡単に配置することができる。   (9) Four locking protrusions 17 are provided to protrude from the frame body 12, and each locking protrusion 17 is provided inside each restricting protrusion 18 in the short side direction (left-right direction) of the frame body 12. Be placed. For this reason, the four latching protrusions 17 can be formed in the two clamping pieces 13 of the frame main body 12, and the frame main body 12 can be formed in a U-shape to open the right side. Therefore, it is possible to form the fixture mounting frame 11 in a U-shape while forming the four locking projections 17 on the frame main body 12, and easily pass the fixture mounting frame 11 through the wall hole Wa. The instrument mounting frame 11 can be easily placed on the back side of the wall material W.

（１０）器具取付枠１１において、各挟持片１３の長辺方向一端側と他端側に規制突部１８を形成するとともに、挟持片１３の一端側の規制突部１８を、連結片１４の幅分だけ内寄りに配置し、他端側の規制突部１８を挟持片１３の他端より外方に突出して配置した。そして、左右の規制突部１８を一つの規制部材とした場合、この規制部材は、挟持片１３の長辺方向に沿って他端側に位置ずれした位置に配置されている。このため、規制部材の両外側端が、壁孔Ｗａの右側面Ｗ３及び左側面Ｗ４に当接した状態では、連結片１４での当接面１２ａ全体が壁材Ｗに当接し、壁孔Ｗａ内に連結片１４が露出していない。よって、左右の規制突部１８の配置を設定することで、器具取付枠１１が壁孔Ｗａを狭めることが防止できる。また、配線器具Ｈを操作することに伴い、器具取付枠１１を壁材Ｗに押し付ける力が作用しても、その力を枠本体１２の三辺（一対の挟持片１３と、連結片１４）で受承することができ、器具取付枠１１が損傷することを防止することができる。   (10) In the instrument mounting frame 11, the restricting protrusions 18 are formed on one end side and the other end side of each holding piece 13 in the long side direction, and the restricting protrusion 18 on one end side of the holding piece 13 is connected to the connecting piece 14. The restricting protrusion 18 on the other end side is disposed so as to protrude outward from the other end of the sandwiching piece 13. When the left and right restricting protrusions 18 are used as one restricting member, the restricting member is disposed at a position displaced to the other end side along the long side direction of the sandwiching piece 13. For this reason, in a state where both outer ends of the regulating member are in contact with the right side surface W3 and the left side surface W4 of the wall hole Wa, the entire contact surface 12a of the connecting piece 14 is in contact with the wall material W, and the wall hole Wa. The connecting piece 14 is not exposed inside. Therefore, it is possible to prevent the instrument mounting frame 11 from narrowing the wall hole Wa by setting the arrangement of the left and right regulating protrusions 18. Moreover, even if the force which presses the fixture mounting frame 11 against the wall material W acts with operation of the wiring fixture H, the force is applied to the three sides of the frame main body 12 (a pair of clamping pieces 13 and a connecting piece 14). It is possible to prevent the instrument mounting frame 11 from being damaged.

（１１）器具取付枠１１の枠本体１２には、規制突部１８に加え、罫書用突起１８ｂが形成されている。このため、規制突部１８により器具取付枠１１を位置決めすることができるとともに、罫書用突起１８ｂにより壁材Ｗに壁孔Ｗａを穿設する作業を簡単に行うことができる。   (11) In addition to the restricting protrusion 18, the ruler protrusion 18b is formed on the frame main body 12 of the instrument mounting frame 11. For this reason, the instrument mounting frame 11 can be positioned by the restricting protrusion 18 and the operation of making the wall hole Wa in the wall material W by the ruled projection 18b can be easily performed.

なお、上記実施形態は以下のように変更してもよい。
○ 実施形態では、規制突部１８に罫書用突起１８ｂを設けたが、罫書用突起１８ｂは無くてもよい。 In addition, you may change the said embodiment as follows.

In the embodiment, in addition to the restricting protrusion 18, the locking protrusion 17 is separately provided on the frame body 12. However, as shown in FIG. 8, only the restricting protrusion 18 is formed and the restricting protrusion 18 is formed. It is good also as a structure which protrudes in the nail | claw piece 18a and the control protrusion 18 serves as a latching | locking part.

このように構成すると、規制突部１８に係止部を一体に設けることとなり、器具取付枠１１の製造コストを抑えることができる。
○ 実施形態では、四つの規制突部１８を、壁孔Ｗａの各角部の内側に配置されるように枠本体１２に設けたが、四つの規制突部１８の位置は、壁孔Ｗａの四つの内側面Ｗ１〜Ｗ４に当接するのであれば、任意に変更してもよい。例えば、各規制突部１８が、各内側面Ｗ１〜Ｗ４の中央に当接するように変更してもよい。この場合、枠本体１２は四角枠状に形成される。 If comprised in this way, the latching | locking part will be integrally provided in the control protrusion 18, and the manufacturing cost of the instrument attachment frame 11 can be held down.
In the embodiment, the four restricting protrusions 18 are provided on the frame main body 12 so as to be arranged inside each corner of the wall hole Wa. However, the four restricting protrusions 18 are positioned at the wall holes Wa. As long as it contacts the four inner side surfaces W1 to W4, it may be arbitrarily changed. For example, each regulation protrusion 18 may be changed so as to contact the center of each inner side surface W1 to W4. In this case, the frame body 12 is formed in a square frame shape.

○ 実施形態では、規制部として四つの規制突部１８に具体化したが、規制部をコ字状をなす突条に具体化してもよい。この突条は、上下両挟持片１３及び連結片１４に跨って延びるように形成される。そして、突条の上面が壁孔Ｗａの上側面Ｗ１に当接するとともに、突条の下面が壁孔Ｗａの下側面Ｗ２に当接する。さらに、突条の左側面が壁孔Ｗａの左側面Ｗ４に当接するとともに、突条の上下両右側端が、壁孔Ｗａの右側面Ｗ３に当接する。   In the embodiment, the four restricting protrusions 18 are embodied as restricting parts, but the restricting part may be embodied as a U-shaped protrusion. This protrusion is formed so as to extend across the upper and lower sandwiching pieces 13 and the connecting piece 14. And while the upper surface of a protrusion contact | abuts to the upper surface W1 of wall hole Wa, the lower surface of a protrusion contact | abuts the lower surface W2 of wall hole Wa. Further, the left side surface of the ridge contacts the left side surface W4 of the wall hole Wa, and the upper and lower right ends of the ridge contact the right side surface W3 of the wall hole Wa.

○ 実施形態では、規制部として四つの規制突部１８に具体化したが、上下右側の規制突部１８のいずれか一つを削除し、三つの規制突部１８としてもよい。このように構成しても、右側の一つの規制突部１８が、壁孔Ｗａの右側面Ｗ３に当接し、残りの左側二つの規制突部１８が、壁孔Ｗａの上側面Ｗ１、下側面Ｗ２、及び左側面Ｗ４に当接するため、三つの規制突部１８が壁孔Ｗａの四つの内側面Ｗ１〜Ｗ４に当接する。   In the embodiment, the four restriction protrusions 18 are embodied as restriction parts. However, any one of the upper and lower right restriction protrusions 18 may be deleted to form three restriction protrusions 18. Even in such a configuration, one right regulation protrusion 18 abuts on the right side surface W3 of the wall hole Wa, and the remaining two left side regulation projections 18 are the upper side surface W1 and the lower side surface of the wall hole Wa. In order to come into contact with W2 and the left side surface W4, the three regulating protrusions 18 come into contact with the four inner side surfaces W1 to W4 of the wall hole Wa.

○ 実施形態では、器具取付枠１１を、取着部としての螺入孔１９及びナットを上下一対備えるタイプに具体化したが、器具取付枠１１を、挟持片１３を長辺方向に延長し、取着部を上下二対以上備えるタイプに変更してもよい。   In the embodiment, the instrument mounting frame 11 is embodied as a type including a pair of upper and lower screw holes 19 and nuts as attachment parts, but the instrument mounting frame 11 is extended in the long side direction of the holding piece 13, You may change into the type provided with two or more pairs of attachment parts.

○ 実施形態では、器具取付枠１１をコ字状にしたが、枠状に変更してもよい。
○ 実施形態では、配線器具Ｈを壁材Ｗに設置する際、ビス２３によって器具取付枠１１と器具保持枠２０を組み付けた状態で、器具取付枠１１を壁材Ｗの裏側に配置するようにしたが、これに限らない。すなわち、器具取付枠１１と器具保持枠２０を組み付けず、器具取付枠１１のみを壁材Ｗの裏側に配置し、その後、ビス２３によって器具取付枠１１に器具保持枠２０を組み付けてもよい。 In embodiment, although the instrument attachment frame 11 was made into U shape, you may change into frame shape.
In the embodiment, when the wiring device H is installed on the wall material W, the device mounting frame 11 is arranged on the back side of the wall material W in a state where the device mounting frame 11 and the device holding frame 20 are assembled by the screws 23. However, it is not limited to this. That is, the appliance mounting frame 11 and the appliance holding frame 20 may not be assembled, and only the appliance mounting frame 11 may be disposed on the back side of the wall material W, and then the appliance holding frame 20 may be assembled to the appliance mounting frame 11 with screws 23.

次に、上記実施形態及び別例から把握できる技術的思想について以下に追記する。
