各収容凹部１１ｃ〜１４ｃにおいて各基部１１ａ〜１４ａをなす収容凹部１１ｃ〜１４ｃの内壁面である収容凹部内壁面１３１〜１３４は、第一突出部及び第二突出部２１〜２４それぞれの下端縁２１ｄ〜２４ｄが当接する面である（図４等参照）。よって、センサ２０Ｒ，２０Ｌの形状に対応して、第二鉤型取付部１２，１４の基部の収容凹部内壁面１３２，１３４の第一方向Ｘに沿った位置は、第一鉤型取付部１１，１３の基部の収容凹部内壁面１３１，１３３よりも下方にずれて配置されている。第二鉤型取付部１２，１４の基部の収容凹部内壁面１３２，１３４は、第一鉤型取付部１１，１３の基部の収容凹部内壁面１３１，１３３よりも、センサ２０Ｒ，２０Ｌの本体部２５Ｒ，２５Ｌの一端縁部２５Ｒ１，２５Ｌ１と他端縁部２５Ｒ２，２５Ｌ２との第一方向Ｘに沿った位置ずれ間隔に等しくずらして形成されている。第三鉤型取付部１３の基部１３ａの収容凹部内壁面１３３の第一方向Ｘに沿った位置は、第二鉤型取付部１２の基部１２ａの収容凹部内壁面１３２よりも上方にずれて配置されており、センサ２０Ｒの第二突出部２２の第一方向Ｘの幅に等しくずらして形成されている。 The housing recess inner wall surfaces 131 to 134, which are the inner wall surfaces of the housing recesses 11c to 14c forming the bases 11a to 14a in the housing recesses 11c to 14c, respectively, have lower end edges 21d of the first projecting portion and the second projecting portions 21 to 24, respectively. It is a surface with which 24 to 24d abut (see FIG. 4 and the like). Therefore, the positions along the first direction X of the housing recess inner wall surfaces 132, 134 of the bases of the second hook-shaped mounting portions 12, 14 are corresponding to the shapes of the sensors 20R, 20L. , 13 are arranged below the accommodating recess inner wall surfaces 131, 133 of the base portions of the base plates 13, 13. The accommodating recess inner wall surfaces 132, 134 of the bases of the second hook-shaped mounting portions 12, 14 have a larger body than the accommodating recess inner wall surfaces 131, 133 of the bases of the first hook-shaped mounting portions 11, 13 of the sensors 20R, 20L. 25R and 25L are formed to be displaced by an equal amount to the positional displacement distance between the one end edge portions 25R1 and 25L1 and the other end edge portions 25R2 and 25L2 along the first direction X. The position of the accommodation recess inner wall surface 133 of the base portion 13a of the third hook-shaped mounting portion 13 along the first direction X is displaced above the accommodation recess inner wall surface 132 of the base portion 12a of the second hook-shaped mounting portion 12. The width of the second protrusion 22 of the sensor 20R is shifted by the same amount as the width in the first direction X.

よって、センサ２０Ｒの第二突出部２２の上端縁２２ｕにセンサ２０Ｌの第一突出部２３の下端縁２３ｄを当接させながら、センサ２０Ｒ及びセンサ２０Ｌの第一突出部及び第二突出部２１〜２４を第一ないし第四の各鉤型取付部１１〜１４に係止可能になる。第一突出部及び第二突出部２１〜２４は、各下端縁２１ｄ〜２４ｄが各基部の収容凹部内壁面１３１〜１３４に当接することで各鉤型取付部１１〜１４に係止され、各基部の収容凹部内壁面１３１〜１３４が第一方向Ｘに沿ってセンサ２０Ｒ,２０Ｌの取付配置を決定する位置決め部となる。 Therefore, while the lower end edge 23d of the first protruding portion 23 of the sensor 20L is brought into contact with the upper end edge 22u of the second protruding portion 22 of the sensor 20R, the first protruding portion and the second protruding portion 21 to of the sensor 20R and the sensor 20L. 24 can be locked to the first to fourth hook-shaped mounting portions 11 to 14. The first projecting portion and the second projecting portions 21 to 24 are locked to the hook-shaped mounting portions 11 to 14 by contacting the lower end edges 21d to 24d with the inner wall surface 131 to 134 of the recessed portion of the base portion, respectively. The accommodation recess inner wall surfaces 131 to 134 of the base portion serve as a positioning portion that determines the mounting arrangement of the sensors 20R and 20L along the first direction X.

また、各収容凹部１１ｃ〜１４ｃにおける第二方向Ｙに沿った間隔は、取付面１６（又は取付基準面１６＊）と、先部１１ｂ〜１４ｂの収容凹部内壁面１４１〜１４４との第二方向Ｙに沿った間隔で表される。先部１１ｂ〜１４ｂの収容凹部内壁面１４１〜１４４は、先部１１ｂ〜１４ｂの収容凹部１１ｃ〜１４ｃの内壁面である。先部１１ｂ〜１４ｂの各収容凹部内壁面１４１〜１４４は、各収容凹部１１ｃ〜１４ｃの開口部から底部に行くのに従って、第二方向Ｙに沿った間隔が小さくなる傾斜状に形成されている。よって、各収容凹部１１ｃ〜１４ｃにおける第二方向Ｙに沿った間隔は、開口部において最も大きく、底部に向けて奥方に行くに従って徐々に小さくなり、各先部１１ｂ〜１４ｂの収容凹部内壁面１４１〜１４４が各基部の収容凹部内壁面１３１〜１３４から斜めに立ち上がる底部において、最も小さい間隔ｆになる。最小間隔ｆは、第一及び第二の各突出部２１〜２４の厚みＴに対応して形成されており、取付面１６と収容凹部１１ｃ〜１４ｃ底部側の各先部１１ｂ〜１４ｂの収容凹部内壁面１４１〜１４４とで各下端縁２１ｄ〜２４ｄを挟持可能に形成されている。よって、センサ２０Ｒ，２０Ｌの第二方向Ｙに沿った取付配置を、本体部２５Ｒ，２５Ｌの背面と取付面１６とが当接する位置に固定することができる。 The intervals along the second direction Y in each of the accommodation recesses 11c to 14c are the second direction between the mounting surface 16 (or the mounting reference surface 16*) and the accommodation recess inner wall surfaces 141 to 144 of the leading portions 11b to 14b. It is represented by the spacing along Y. The accommodation recess inner wall surfaces 141 to 144 of the front portions 11b to 14b are the inner wall surfaces of the accommodation recess portions 11c to 14c of the front portions 11b to 14b. The accommodation recess inner wall surfaces 141 to 144 of the front portions 11b to 14b are formed in an inclined shape in which the intervals along the second direction Y become smaller as going from the openings of the accommodation recesses 11c to 14c to the bottom. .. Therefore, the space in each of the accommodation recesses 11c to 14c along the second direction Y is the largest at the opening, and gradually decreases toward the bottom toward the bottom, and the accommodation recess inner wall surface 141 of each of the tip portions 11b to 14b. ˜144 has the smallest interval f in the bottom portion that obliquely rises from the accommodation recess inner wall surfaces 131 to 134 of each base portion. The minimum distance f is formed corresponding to the thickness T of each of the first and second protrusions 21 to 24, and the accommodating recesses of the mounting surface 16 and the accommodating recesses 11c to 14c on the bottom side of the front ends 11b to 14b. The lower end edges 21d to 24d can be sandwiched between the inner wall surfaces 141 to 144. Therefore, the mounting arrangement of the sensors 20R and 20L along the second direction Y can be fixed at a position where the rear surfaces of the main body portions 25R and 25L and the mounting surface 16 are in contact with each other.

また、各鉤型取付部１１〜１４の基部１１ａ〜１４ａにおけるつけ根縁部１１１〜１１４は、本体部２５Ｒ，２５Ｌの第三方向の幅Ｗに対応した間隔を置いて（図２参照）、第三方向Ｚに沿って取付面１６上にそれぞれ配置されている。具体的には、第一及び第三の各鉤型取付部１１，１３と第二及び第四の鉤型取付部１２，１４との、第三方向Ｚに沿って互いに相手の側を向く内端面１１ｉｎ，１３ｉｎと内端面１２ｉｎ，１４ｉｎ間の間隔Ｄ（図３参照）は、本体部２５Ｒ、２５Ｌの幅Ｗに等しい。また、第二鉤型取付部１２の外端面１２ｏｕｔと第三鉤型取付部１３の外端面１３ｏｕｔ間の第三方向Ｚの間隔Ｇは、センサ２０Ｒの第二突出部２２及びセンサ２０Ｌの第一突出部２３の第三方向Ｚへの突出長よりもやや大きく形成されている。 In addition, the base edge portions 111 to 114 of the base portions 11a to 14a of the hook-shaped attachment portions 11 to 14 are spaced at intervals corresponding to the width W of the body portions 25R and 25L in the third direction (see FIG. 2). They are respectively arranged on the mounting surface 16 along the three directions Z. Specifically, the insides of the first and third hook-shaped mounting portions 11, 13 and the second and fourth hook-shaped mounting portions 12, 14 that face each other along the third direction Z. The distance D (see FIG. 3) between the end surfaces 11in and 13in and the inner end surfaces 12in and 14in is equal to the width W of the body portions 25R and 25L. Further, the gap G in the third direction Z between the outer end surface 12out of the second hook-shaped mounting portion 12 and the outer end surface 13out of the third hook-shaped mounting portion 13 is equal to the first protrusion 22 of the sensor 20R and the first of the sensor 20L. It is formed to be slightly longer than the protruding length of the protruding portion 23 in the third direction Z.

よって、本体部２５Ｒを、第一及び第二の各鉤型取付部１１，１２間に、第一方向Ｘに沿って挿入することで、センサ２０Ｒを第三方向Ｚに沿って位置決めして取り付けることができる。次に、本体部２５Ｌを、第三及び第四の各鉤型取付部１３，１４間に、第一方向Ｘに沿って挿入することで、センサ２０Ｌを第三方向Ｚに沿って位置決めして取り付けることができる。この際、センサ２０Ｌの第一突出部２３の下端縁２３ｄがセンサ２０Ｒの第二突出部２２の上端縁２２ｕ上に当接するように、センサ２０Ｌを第一方向Ｘ及び第三方向Ｚに沿って位置決めして取り付けることができる。 Therefore, by inserting the main body portion 25R between the first and second hook-shaped attachment portions 11 and 12 along the first direction X, the sensor 20R is positioned and attached along the third direction Z. be able to. Then, the main body portion 25L is inserted between the third and fourth hook-shaped attachment portions 13 and 14 along the first direction X to position the sensor 20L along the third direction Z. Can be installed. At this time, the sensor 20L is moved along the first direction X and the third direction Z so that the lower end edge 23d of the first projecting portion 23 of the sensor 20L abuts on the upper end edge 22u of the second projecting portion 22 of the sensor 20R. It can be positioned and attached.

（抜け止め防止部）
抜け止め防止部１７は、エンボス状に第二方向Ｙに沿って前端側に凸設され、第三方向Ｚに沿って第二鉤型取付部１２と第三鉤型取付部１３との間に配置して形成されている。また、抜け止め防止部１７は、第三鉤型取付部１３の収容凹部１３ｃの開口を臨む基部１３ａの収容凹部内壁面１３３から、第一突出部２３の第一方向Ｘに沿った幅分だけ同方向に離間した位置に配置されている。これにより、第一突出部２３の下端縁２３ｄを基部１３ａの収容凹部内壁面１３３に当接させるとともに、上端縁２３ｕを抜け止め防止部１７の取付面１６からの立ち上がり面１７ａ（図４参照）に当接させる。よって、第一突出部２３が第一方向Ｘに沿って移動するのを規制し、鉤型取付部１３の開口部から反対側に抜け出すのを防止する。また、第一突出部２３の下端縁２３ｄは、第二鉤型取付部１２の収容凹部１２ｃの基部の収容凹部内壁面１３２に係止する第二突出部２２の上端縁２２ｕに当接している。この構成により、センサ２０Ｒ，２０Ｌの双方が第一方向Ｘに沿って移動することを規制できる。 (Prevention prevention part)
The retaining portion 17 is embossed on the front end side along the second direction Y and extends between the second hook-shaped mounting portion 12 and the third hook-shaped mounting portion 13 along the third direction Z. It is arranged and formed. Further, the retaining portion 17 is provided only by the width along the first direction X of the first protruding portion 23 from the inner wall surface 133 of the housing recess of the base 13a facing the opening of the housing recess 13c of the third hook-shaped mounting portion 13. They are arranged at positions separated in the same direction. Thereby, the lower end edge 23d of the first projecting portion 23 is brought into contact with the inner wall surface 133 of the housing recess of the base portion 13a, and the upper end edge 23u rises from the mounting surface 16 of the retaining portion 17 (see FIG. 4). Abut. Therefore, the first projecting portion 23 is restricted from moving along the first direction X, and is prevented from coming out from the opening of the hook-shaped mounting portion 13 to the opposite side. Further, the lower end edge 23d of the first protruding portion 23 is in contact with the upper end edge 22u of the second protruding portion 22 that is locked to the housing recess inner wall surface 132 of the base of the housing recess 12c of the second hook-shaped mounting portion 12. .. With this configuration, it is possible to prevent both the sensors 20R and 20L from moving along the first direction X.

（切り込み）
また、図２に示すように、上記のエンボス状の抜け止め防止部１７の近傍であって、抜け止め防止部１７から左右両方向に離間した取付面１６には、取付板１５の裏面側に貫通する第一方向Ｘに沿った直線細溝状の２本の切り込み１８が形成されている。よって、センサ２０Ｒ，２０Ｌ取り付ける際に、抜け止め防止部１７が、第二突出部２２，第一突出部２３の裏面で圧接されることによって、取付面１６に対して容易に押し込まれるため、センサ２０Ｒ，２０Ｌをスムーズにスライド移動させることができる。 (Cut)
Further, as shown in FIG. 2, a mounting surface 16 near the embossed retaining portion 17 and separated from the retaining portion 17 in both left and right directions penetrates the rear surface of the mounting plate 15. Two linear groove-like cuts 18 are formed along the first direction X. Therefore, when attaching the sensors 20R and 20L, the retaining prevention portion 17 is easily pressed against the attachment surface 16 by being pressed into contact with the rear surfaces of the second protruding portion 22 and the first protruding portion 23. 20R and 20L can be smoothly slid.

（センサの取付構造の製造方法）
次に、第一実施形態のセンサの取付構造ＳＴ１の製造方法について説明する。上述した各鉤型取付部１１〜１４が形成された取付板１５の取付面１６に、センサ２０Ｒ，２０Ｌを取り付けるには、以下のように行う。まず、右側センサ２０Ｒを、第一及び第二の各鉤型取付部１１，１２の開口側から底部に向けて、第一方向Ｘに沿って取付面１６上をスライド移動させる。その際、本体部２５Ｒを鉤型取付部１１，１２の内端面１１ｉｎ，１２ｉｎにあてがいながらスライドさせる。内端面１１ｉｎ，１２ｉｎ間の第三方向Ｚの間隔Ｄが本体部２５Ｒの第三方向の幅Ｗに等しいので、センサ２０Ｒの第三方向Ｚに位置決めしながらスライド移動できる。 (Method for manufacturing sensor mounting structure)
Next, a method for manufacturing the sensor mounting structure ST1 of the first embodiment will be described. The sensors 20R and 20L are mounted on the mounting surface 16 of the mounting plate 15 on which the hook-shaped mounting portions 11 to 14 are formed as follows. First, the right sensor 20R is slid on the mounting surface 16 along the first direction X from the opening side of each of the first and second hook-shaped mounting portions 11 and 12 toward the bottom. At that time, the main body portion 25R is slid while being applied to the inner end surfaces 11in and 12in of the hook-shaped mounting portions 11 and 12. Since the distance D in the third direction Z between the inner end surfaces 11in and 12in is equal to the width W of the main body 25R in the third direction, the sensor 20R can be slid while being positioned in the third direction Z.

また、この際に、センサ２０Ｒの第一突出部２１及び第二突出部２２は、各鉤型取付部１１，１２の各つけ根縁部１１１，１１２よりも第三方向Ｚに沿って本体部２５Ｒより左右方向外側に突出して配置されている。よって、第二突出部２２の裏面によって抜け止め防止部１７を取付板１５の裏面側に押し込みながらスライド移動させる。抜け止め防止部１７の近傍には、切り込み１８が設けられており、抜け止め防止部１７を裏面側に容易に押し込み可能になっており、センサ２０Ｒをスライド移動させる操作性が良くなっている。第二突出部２２の上端縁２２ｕが抜け止め防止部１７を乗り越えるように、センサ２０Ｒを第一方向Ｘにスライド移動させる。 In addition, at this time, the first protruding portion 21 and the second protruding portion 22 of the sensor 20R have a main body portion 25R along the third direction Z rather than the root edge portions 111, 112 of the hook-shaped mounting portions 11, 12. It is arranged so as to project further outward in the left-right direction. Therefore, the retaining portion 17 is slid while being pushed toward the rear surface of the mounting plate 15 by the rear surface of the second protruding portion 22. A notch 18 is provided in the vicinity of the retaining prevention portion 17, so that the retaining prevention portion 17 can be easily pushed to the back surface side, and the operability of sliding the sensor 20R is improved. The sensor 20R is slid in the first direction X so that the upper edge 22u of the second protrusion 22 rides over the retaining portion 17.

そして、第一突出部２１を第一鉤型取付部１１に、及び第二突出部２２を第二鉤型取付部１２に係止させる。第一及び第二の各突出部２１，２２の下端縁２１ｄ、２２ｄを、各収容凹部１１ｃ、１２ｃの開口縁にあてがい、各突出部２１，２２を各収容凹部１１ｃ、１２ｃの底部に向けて挿入する。各先部１１ｂ，１２ｂの収容凹部内壁面１４１，１４２の斜面上を各突出部２１，２２の各下端縁２１ｄ，２２ｄで摺るように、第一及び第二の各突出部２１，２２を、第一方向Ｘに沿って各収容凹部１１ｃ，１２ｃの奥方に押し込む。先部１１ｂ，１２ｂの収容凹部内壁面１４１，１４２は、収容凹部１１ｃ，１２ｃの底部に近づくに従って、取付面１６又は取付基準面１６＊との離間距離が小さくなっており、第一及び第二の各突出部の下端縁２１ｄ、２２ｄは、第二方向Ｙに沿って前側から後側に、すなわち取付面１６又は取付基準面１６＊側に引寄せられる。各下端縁２１ｄ，２２ｄが基部１１ａ，１２ａの収容凹部内壁面１３１，１３２近傍まで到達するとともに、先部１１ｂ，１２ｂの収容凹部内壁面１４１，１４２によって取付面１６側に押圧される。このようにして、センサ２０Ｒを、第一及び第二の各突出部２１，２２を介して、第一方向Ｘ及び第二方向Ｙに沿って位置決めされた場所に取り付ける。 Then, the first protruding portion 21 is locked to the first hook-shaped mounting portion 11, and the second protruding portion 22 is locked to the second hook-shaped mounting portion 12.

It pushes in the inner side of each accommodation recessed part 11c, 12c along the 1st direction X. The accommodation recess inner wall surfaces 141, 142 of the front portions 11b, 12b have a smaller distance from the mounting surface 16 or the mounting reference surface 16* as they approach the bottoms of the housing recesses 11c, 12c. The lower end edges 21d and 22d of each of the protrusions are attracted from the front side to the rear side along the second direction Y, that is, to the mounting surface 16 or the mounting reference surface 16* side. The lower end edges 21d and 22d reach the vicinity of the accommodation recess inner wall surfaces 131 and 132 of the base portions 11a and 12a, and are pressed toward the mounting surface 16 side by the accommodation recess inner wall surfaces 141 and 142 of the tip portions 11b and 12b. In this way, the sensor 20R is attached to the location positioned along the first direction X and the second direction Y via the first and second protrusions 21 and 22.

さらに、左側センサ２０Ｌを、右側センサ２０Ｒと同様に第一方向Ｘにスライド移動させて取り付ける。まず、本体部２５Ｌを鉤型取付部１３，１４の内端面１３ｉｎ，１４ｉｎにあてがいながらスライドさせ、センサ２０Ｌの第三方向Ｚの配置を位置決めする。 Further, the left sensor 20L is slid in the first direction X and attached in the same manner as the right sensor 20R. First, the main body portion 25L is slid while being applied to the inner end surfaces 13in and 14in of the hook-shaped mounting portions 13 and 14 to position the sensor 20L in the third direction Z.

この際に、第一突出部２３の裏面によって抜け止め防止部１７を取付板１５の裏面側に押し込みながら、第一突出部２３が抜け止め防止部１７を乗り越えるまで、センサ２０Ｌを第一方向Ｘにスライド移動させる。第一突出部２３が抜け止め防止部１７を乗り越える位置では、第一突出部２３の上端縁２３ｕが抜け止め防止部１７に係止し、第一突出部２３の下端縁２３ｄがセンサ２０Ｒの第二突出部２２の上端縁２２ｕに当接し、センサ２０Ｒ及びセンサ２０Ｌの第一方向Ｘに沿った移動が規制される。 At this time, the sensor 20L is moved in the first direction X until the first protrusion 23 passes over the retaining portion 17 while pushing the retaining portion 17 by the rear surface of the first protruding portion 23 toward the rear surface of the mounting plate 15.

以上詳述したとおり、上記の第一実施形態によれば、取付板１５（取付先部材）の取付面１６にセンサ２０Ｒ，２０Ｌが取り付けられているセンサの取付構造ＳＴ１であって、センサ２０Ｒは、取付面１６に取り付けるための被取付部である第一突出部２１及び第二突出部２２を有し、センサ２０Ｌは、同様の第一突出部２３及び第二突出部２４を有し、取付板１５の取付面１６には、第一及び第二の各突出部２１〜２４が取り付けられる４つの鉤型に形成された第一ないし第四の各鉤型取付部１１〜１４が設けられ、第一ないし第四の各鉤型取付部１１〜１４は、取付面１６から凸設されている基部１１ａ〜１４ａと、基部１１ａ〜１４ａの先端から取付面１６に対向して延設されている先部１１ｂ〜１４ｂと、突出部２１〜２４が収容される収容凹部１１ｃ〜１４ｃと、から構成されており、各基部１１ａ〜１４ａの収容凹部内壁面１３１〜１３４は、第一及び第二の各突出部２１〜２４の下端縁（一端）２１ｄ〜２４ｄが当接し、各先部１１ｂ〜１４ｂの収容凹部内壁面１４１〜１４４は、各収容凹部１１ｃ〜１４ｃの開口から底部に行くに従って取付面１６に接近するように傾斜しており、各収容凹部１１ｃ〜１４ｃに収容されている第一及び第二の各突出部２１〜２４を取付面１６に押圧し、取付面１６には、収容凹部１３ｃの開口から所定距離だけ離れた位置に凸設され、第一突出部２３の上端縁（他端）２３ｕが当接する抜け止め防止部１７をさらに備えている。 (Operation and effect of the first embodiment)
As described in detail above, according to the first embodiment described above, the sensor mounting structure ST1 has the sensors 20R and 20L mounted on the mounting surface 16 of the mounting plate 15 (mounting destination member). , The first protrusion 21 and the second protrusion 22 that are the attached portions for attachment to the attachment surface 16, and the sensor 20L has the same first protrusion 23 and the second protrusion 24, and The mounting surface 16 of the plate 15 is provided with first to fourth hook-shaped mounting portions 11 to 14 formed in four hook shapes to which the first and second protrusions 21 to 24 are mounted. Each of the first to fourth hook-shaped attachment portions 11 to 14 extends from the attachment surface 16 so as to project from the base portions 11a to 14a, and the tip ends of the base portions 11a to 14a extend to face the attachment surface 16. Each of the bases 11a to 14a has an inner wall surface 131 to 134, which is a first and a second inner wall surface 131 to 134 of the base portion 11a to 14a. The lower end edges (one end) 21d to 24d of the respective projecting portions 21 to 24 are in contact with each other, and the accommodation recess inner wall surfaces 141 to 144 of the respective front portions 11b to 14b are attached to the mounting recesses 11c to 14c from the opening to the bottom. 16, the first and second protrusions 21 to 24 housed in the housing recesses 11c to 14c are pressed against the mounting surface 16, and the mounting surface 16 receives the housing recesses. The retainer 17 is further provided at a position spaced apart from the opening of the portion 13c by a predetermined distance, and comes in contact with the upper end (the other end) 23u of the first protrusion 23.

よって、センサ２０Ｒを取付板１５に取り付ける際には、取付板１５の取付面１６に平行な所定方向であって、収容凹部１１ｃ、１２ｃの開口から底部に向けた第一方向Ｘに沿って、センサ２０Ｒをスライド移動させる。この操作により、センサ２０Ｒの各突出部２１，２２を各鉤型取付部１１，１２の収容凹部１１ｃ，１２ｃに挿入する。各基部１１ａ，１２ａの収容凹部内壁面１３１，１３２に各突出部の下端縁（一端）２１ｄ，２２ｄを当接させ、各鉤型取付部１１，１２に突出部２１，２２を係止させることができる。次に、センサ２０Ｌを取付板１５に取り付ける際にも、同様に、センサ２０Ｌをスライド移動させる操作により、各基部１３ａ，１４ａの収容凹部内壁面１３３，１３４に各突出部の下端縁（一端）２３ｄ，２４ｄを当接させ、各鉤型取付部１３，１４に各突出部２３，２４を係止させることができる。 Therefore, when the sensor 20R is attached to the attachment plate 15, along a first direction X parallel to the attachment surface 16 of the attachment plate 15 and extending from the openings of the accommodation recesses 11c and 12c toward the bottom, The sensor 20R is slid. By this operation, the protrusions 21 and 22 of the sensor 20R are inserted into the housing recesses 11c and 12c of the hook-shaped mounting portions 11 and 12, respectively. Lower end edges (one end) 21d, 22d of each protrusion are brought into contact with the housing recess inner wall surfaces 131, 132 of each base 11a, 12a, and the protrusions 21, 22 are locked to each hook-shaped mounting portion 11, 12. You can Next, when the sensor 20L is attached to the mounting plate 15, the lower end edge (one end) of each protruding portion is similarly formed on the accommodation recess inner wall surface 133, 134 of each base 13a, 14a by sliding the sensor 20L. The protrusions 23 and 24 can be locked to the hook-shaped mounting portions 13 and 14 by abutting 23d and 24d.

また、取付面１６には、収容凹部１３ｃの開口から所定距離だけ離れた位置に凸設され、第一突出部２３の上端縁（他端）２３ｕが当接する抜け止め防止部１７が設けられている。よって、まず、センサ２０Ｒをスライド移動させる際には、抜け止め防止部１７を第二突出部２２の裏面で圧接し、第二突出部２２の上端縁２２ｕが抜け止め防止部１７を乗り越えるように、スライド移動させる作業を行う。次に、センサ２０Ｌをスライド移動させる際には、第一突出部２３の上端縁２３ｕが抜け止め防止部１７を乗り越えて当接するまで、スライド移動させる作業を行う。これにより、各突出部２１〜２４を各鉤型取付部１１〜１４に係止して配置した状態を維持して、確実にセンサ２０Ｒ，２０Ｌを取付板１５に取り付けることができる。 Further, the attachment surface 16 is provided with a retaining prevention portion 17 which is provided at a position spaced apart from the opening of the accommodation recess 13c by a predetermined distance and which is in contact with the upper end edge (the other end) 23u of the first protrusion 23. There is. Therefore, first, when the sensor 20R is slid, the retaining prevention portion 17 is pressed against the back surface of the second protruding portion 22 so that the upper end edge 22u of the second protruding portion 22 passes over the retaining prevention portion 17. , Perform the work of sliding. Next, when sliding the sensor 20L, the work of sliding the sensor 20L is performed until the upper end edge 23u of the first projecting portion 23 passes over and comes into contact with the retaining prevention portion 17. As a result, the sensors 20R and 20L can be reliably attached to the attachment plate 15 while maintaining the state in which the protrusions 21 to 24 are locked and arranged on the hook-shaped attachment portions 11 to 14, respectively.

このように取付板１５にセンサ２０Ｒ，２０Ｌが取り付けられた状態では、センサ２０Ｌの第一突出部２３の下端縁２３ｄは、第三鉤型取付部１３の基部の収容凹部内壁面１３３に当接しており、第一突出部２３の上端縁２３ｕは、抜け止め防止部１７に当接している。また、センサ２０Ｒの第二突出部２２の下端縁２２ｄは、第二鉤型取付部１２の基部の収容凹部内壁面１３２に当接している。第二突出部２２の上端縁２２ｕは、センサ２０Ｌの第一突出部２３の下端縁２３ｄに当接しており、その第一突出部２３を介して、間接的に、抜け止め防止部１７に係止されている。よって、第二突出部２２及び第一突出部２３は、第一方向Ｘに沿って移動することが規制され、センサ２０Ｒ，２０Ｌを取付板１５に取り付けた配置状態が確実に維持されている。 In the state where the sensors 20R and 20L are attached to the attachment plate 15 in this manner, the lower end edge 23d of the first protrusion 23 of the sensor 20L abuts the accommodation recess inner wall surface 133 of the base of the third hook-shaped attachment portion 13. The upper end edge 23u of the first protruding portion 23 is in contact with the retaining prevention portion 17. Further, the lower end edge 22d of the second protruding portion 22 of the sensor 20R is in contact with the inner wall surface 132 of the housing recess of the base of the second hook-shaped mounting portion 12. The upper end edge 22u of the second protruding portion 22 is in contact with the lower end edge 23d of the first protruding portion 23 of the sensor 20L, and is indirectly connected to the retaining prevention portion 17 via the first protruding portion 23. It has been stopped. Therefore, the second protrusion 22 and the first protrusion 23 are restricted from moving along the first direction X, and the arrangement state in which the sensors 20R and 20L are attached to the attachment plate 15 is reliably maintained.

また、取付板１５にセンサ２０Ｒ，２０Ｌが取り付けられた状態では、各収容凹部１１ｃ〜１４ｃに収容されている各突出部２１〜２４は、開口から底部に行くに従って取付面１６に接近するように傾斜する各先部１１ｂ〜１４ｂの収容凹部内壁面１４１〜１４４によって取付面１６に押圧されている。よって各突出部２２〜２４は、第二方向Ｙに沿って移動することが規制されている。センサ２０Ｒ，２０Ｌを取付板１５に取り付けた配置状態が確実に維持されている。 Further, in the state where the sensors 20R and 20L are attached to the attachment plate 15, the protrusions 21 to 24 accommodated in the accommodation recesses 11c to 14c approach the attachment surface 16 from the opening to the bottom. It is pressed against the mounting surface 16 by the accommodating recess inner wall surfaces 141 to 144 of the inclined front portions 11b to 14b. Therefore, the protrusions 22 to 24 are restricted from moving in the second direction Y. The arrangement state in which the sensors 20R and 20L are attached to the attachment plate 15 is reliably maintained.

従って、従来技術のようにボルト、ビス等の別途の取付部品を用いて作業を行うよりも、容易に取付板１５にセンサ２０Ｒ，２０Ｌを取り付け、第一方向Ｘ及び第二方向Ｙにセンサ２０Ｒ，２０Ｌを固定することができる。また、良好な取付状態を維持しながら、必要に応じて容易に取り外すことができる。さらに、先部１１ｂ〜１４ｂの傾斜角によって、第二方向Ｙに沿ってセンサ２０Ｒ，２０Ｌを取付面１６の側に付勢する押付け力の加減を調節することができる。よって、ボルト、ビス等の取付部品を用いて作業者の技量によりねじ締めを行い取付作業するよりも、センサ２０Ｒ，２０Ｌを取付板１５に取り付ける製造工程の管理を容易に行うことができる。 Therefore, the sensors 20R and 20L can be easily attached to the attachment plate 15 and the sensor 20R can be attached to the first direction X and the second direction Y more easily than in the case of performing work using separate attachment parts such as bolts and screws as in the prior art. , 20L can be fixed. Further, it can be easily removed as needed while maintaining a good attachment state. Furthermore, the inclination angle of the front portions 11b to 14b can adjust the amount of pressing force that urges the sensors 20R and 20L toward the mounting surface 16 along the second direction Y. Therefore, it is possible to easily manage the manufacturing process of mounting the sensors 20R and 20L on the mounting plate 15 as compared with the mounting work by tightening the screw with the skill of the operator using the mounting parts such as bolts and screws.

また、センサ２０Ｒ，２０Ｌは、本体部２５Ｒ，２５Ｌの一端縁部２５Ｒ１，２５Ｌ１及び一端縁部２５Ｒ１，２５Ｌ１と反対側にある他端縁部２５Ｒ２，２５Ｌ２から外側に向けてそれぞれ延設され、かつ取付面１６と平行をなす板状に形成されている第一突出部２１，２３及び第二突出部２２，２４と、を有し、第一突出部２１，２３及び第二突出部２２，２４は、被取付部であり、センサの取付構造ＳＴ１は、板状に形成されかつ第一突出部２１，２３に係止されている鉤型取付部である第一及び第三の各鉤型取付部１１，１３と、板状に形成されかつ第二突出部２２，２４に係止されている鉤型取付部である第二及び第四の各鉤型取付部１２，１４と、を有し、第一及び第三の各鉤型取付部１１，１３と第二及び第四の各鉤型取付部１２，１４とは、本体部２５Ｒ，２５Ｌの一端縁部２５Ｒ１，２５Ｌ１と他端縁部２５Ｒ２，２５Ｌ２との幅Ｗに等しい間隔Ｄだけ離間させて配置されている。 Further, the sensors 20R and 20L extend outward from the one end edge portions 25R1 and 25L1 of the main body portions 25R and 25L and the other end edge portions 25R2 and 25L2 opposite to the one end edge portions 25R1 and 25L1 respectively, and The first protrusions 21 and 23 and the second protrusions 22 and 24 that are formed in a plate shape that is parallel to the mounting surface 16 are provided, and the first protrusions 21 and 23 and the second protrusions 22 and 24 are included. Is a part to be mounted, and the sensor mounting structure ST1 is a hook-shaped mounting part formed in a plate shape and locked to the first protrusions 21 and 23. And parts 11 and 13, and second and fourth hook-shaped mounting portions 12 and 14 which are hook-shaped mounting portions formed in a plate shape and locked to the second protruding portions 22 and 24. , The first and third hook-shaped mounting portions 11 and 13 and the second and fourth hook-shaped mounting portions 12 and 14 are one end edge portions 25R1 and 25L1 and the other end edge portions of the main body portions 25R and 25L. 25R2 and 25L2 are spaced apart by a distance D equal to the width W.

よって、各センサ２０Ｒ，２０Ｌが１つのセンサ２０Ｒ又はセンサ２０Ｌの２つの第一及び第二の各突出部２１，２２又は２つの第一及び第二の各突出部２３，２４を用いて、２カ所の第一及び第二の各鉤型取付部１１，１２又は２カ所の第三及び第四の各鉤型取付部１３，１４に取り付けられている。よって、簡易な構成で、１カ所で取り付けるよりも取付状態を安定化できる。 Therefore, each sensor 20R, 20L uses one sensor 20R or two first and second protrusions 21 and 22 of the sensor 20L or two first and second protrusions 23 and 24, respectively. It is attached to each of the first and second hook-shaped attachment portions 11 and 12 at one place or to each of the third and fourth hook-shaped attachment portions 13 and 14 at two places. Therefore, with a simple structure, the mounting state can be stabilized rather than mounting at one location.

また、第一及び第三の各鉤型取付部１１，１３と第二及び第四の各鉤型取付部１２，１４との第三方向Ｚに沿った間隔Ｄ，Ｄが、各本体部２５Ｒ，２５Ｌの各第一突出部２１，２３の付け根に相当する一端縁部２５Ｒ１，２５Ｌ１と各第二突出部２２，２４の付け根に相当する他端縁部２５Ｒ２，２５Ｌ２との、第三方向Ｚに沿った幅Ｗに等しく形成されている。よって、本体部２５Ｒ又は本体部２５Ｌをスライド移動させて第一鉤型取付部１１と第二鉤型取付部１２間、又は、第三鉤型取付部１３と第四鉤型取付部１４間に本体部２５Ｒ又は本体部２５Ｌを挿入するとともに、第一ないし第四の各鉤型取付部１１〜１４の収容凹部１１ｃ〜１４ｃに第一及び第二の各突出部２１〜２４を収容することができる。各鉤型取付部１１〜１４を取付板１５に対するセンサ２０Ｒ，２０Ｌの第一方向Ｘの移動規制部とするとともに、第三方向Ｚの取付位置決め部としても機能させることができる。 Further, the distances D and D along the third direction Z between the first and third hook-shaped mounting portions 11 and 13 and the second and fourth hook-shaped mounting portions 12 and 14 are the main body portions 25R. , 25L, one end edge portion 25R1, 25L1 corresponding to the root of each first protruding portion 21, 23 and the other end edge portion 25R2, 25L2 corresponding to the root of each second protruding portion 22, 24 in the third direction Z. The width W is equal to the width W. Therefore, the main body portion 25R or the main body portion 25L is slid to move between the first hook-shaped mounting portion 11 and the second hook-shaped mounting portion 12, or between the third hook-shaped mounting portion 13 and the fourth hook-shaped mounting portion 14. While inserting the main body portion 25R or the main body portion 25L, the first and second protruding portions 21 to 24 can be housed in the housing recesses 11c to 14c of the first to fourth hook-shaped mounting portions 11 to 14, respectively. it can. The hook-shaped mounting portions 11 to 14 can function as the movement restricting portions of the sensors 20R and 20L with respect to the mounting plate 15 in the first direction X, and can also function as the mounting positioning portions in the third direction Z.

さらに、第一及び第二の各突出部２１〜２４が板状なので、一般的に厚みが大きくなく、コンパクトに形成された第一ないし第四の各鉤型取付部１１〜１４の収容凹部１１ｃ〜１４ｃに第一及び第二の各突出部２１〜２４を容易に収容できる。しかも取付面１６と第一及び第二の各突出部２１〜２４の板表面との面同士で当接可能になり、取付状態を安定させて維持し易くなる。よって、ボルト、ビス等の取付部品を用いる場合と比較して、取付板１５へのセンサ２０Ｒ，２０Ｌの取付状態の安定性を損なわずに、取り付け作業を容易に行うことができる。 Furthermore, since the first and second protrusions 21 to 24 are plate-shaped, the thickness is not generally large, and the accommodating recesses 11c of the first to fourth hook-shaped mounting portions 11 to 14 are compact. It is possible to easily accommodate the first and second protrusions 21 to 24 in 14 to 14c. Moreover, the mounting surface 16 and the plate surfaces of the first and second projecting portions 21 to 24 can come into contact with each other, and the mounting state can be easily stabilized and maintained. Therefore, as compared with the case where mounting parts such as bolts and screws are used, the mounting work can be easily performed without impairing the stability of the mounting state of the sensors 20R and 20L to the mounting plate 15.

また、抜け止め防止部１７の近傍には、取付板１５を厚み方向に貫通する細溝状の切り込み１８が設けられている。よって、取付板１５の強度を損なわずに抜け止め防止部１７近傍の可撓性を大きくでき、抜け止め防止部１７を押し込む際の抵抗力を小さくできる。抜け止め防止部１７を取付板１５の裏面側に押し込むことが容易になり、センサ２０Ｒ，２０Ｌの取り付け作業をさらに容易に行うことができる。 Further, in the vicinity of the retaining prevention portion 17, a narrow groove-shaped cut 18 is provided which penetrates the mounting plate 15 in the thickness direction.

The sensors 20R and 20L are formed so that they can be prevented from coming off by being locked to the upper edge 24u.

（第二実施形態の作用効果）
第二実施形態のセンサの取付構造ＳＴ２によれば、取付面１６には、第一、三、四の各鉤型取付部１１，１３，１４の収容凹部１１ｃ，１３ｃ，１４ｃの開口部を臨む基部１１ａ，１３ａ，１４ａの収容凹部内壁面１３１，１３３，１３４から、第一及び第二の各突出部２１，２３，２４の第一方向Ｘに沿った幅分だけ同方向に離れた位置に凸設され、センサ２０Ｒの第一突出部２１の上端縁２１ｕ、センサ２０Ｌの第一突出部２３の上端縁２３ｕ，第二突出部２４の上端縁２４ｕが当接する抜け止め防止部１７２が形成されている。 (Operation and effect of the second embodiment)
According to the sensor mounting structure ST2 of the second embodiment, the mounting surface 16 faces the openings of the housing recesses 11c, 13c, 14c of the first, third, and fourth hook-shaped mounting portions 11, 13, 14, respectively. From the inner wall surface 131, 133, 134 of the recessed portion of the base 11a, 13a, 14a to a position separated by the width of the first and second protrusions 21, 23, 24 along the first direction X in the same direction. A retaining prevention portion 172 that is provided in a protruding manner and is in contact with the upper edge 21u of the first protruding portion 21 of the sensor 20R, the upper edge 23u of the first protruding portion 23 of the sensor 20L, and the upper edge 24u of the second protruding portion 24 is formed. ing.

よって、センサ２０Ｒを取付板１５に取り付ける際には、第一実施形態と同様に、第一方向Ｘに沿って、センサ２０Ｒをスライド移動させる。この操作により、各基部１１ａ，１２ａの収容凹部内壁面１３１，１３２に各突出部の下端縁（一端）２１ｄ，２２ｄを当接させ、鉤型取付部１１，１２に各突出部２１，２２を係止させることができる。また、突出部２１の上端縁２１ｕが抜け止め防止部１７２の下端縁１７２ｄを乗り越えて立ち上がり面１７２ａに当接するまで、スライド移動させる作業を行う。突出部２１の下端縁２１ｄは、鉤型取付部１１の基部の収容凹部内壁面１３１に当接しており、上端縁２１ｕは、抜け止め防止部１７２に係止する。よって、第一突出部２１は、第一方向Ｘに沿って移動することが規制され、センサ２０Ｒを取付板１５に取り付けた配置状態が維持されている。 Therefore, when mounting the sensor 20R on the mounting plate 15, the sensor 20R is slid along the first direction X, as in the first embodiment. By this operation, the lower end edges (one end) 21d, 22d of the respective projecting portions are brought into contact with the housing recess inner wall surfaces 131, 132 of the respective base portions 11a, 12a, and the respective projecting portions 21, 22 are attached to the hook-shaped mounting portions 11, 12. It can be locked. Further, the work of sliding the upper end edge 21u of the protrusion 21 over the lower end edge 172d of the retaining portion 172 and contacting the rising surface 172a is performed. A lower end edge 21d of the protruding portion 21 is in contact with an inner wall surface 131 of the recessed portion of the base of the hook-shaped mounting portion 11, and an upper end edge 21u thereof is locked by the retaining portion 172. Therefore, the first protrusion 21 is restricted from moving along the first direction X, and the arrangement state in which the sensor 20R is attached to the attachment plate 15 is maintained.

次に、同様に、センサ２０Ｌを取付板１５に取り付ける際には、センサ２０Ｒが取付板１５に取り付けられた配置状態を確実に維持した上で、センサ２０Ｌの取付作業を行うことができる。センサ２０Ｒと同様に、センサ２０Ｌをスライド移動させる操作により、第一及び第二の突出部２３，２４の下端縁２３ｄ，２４ｄを、鉤型取付部１３，１４の基部の収容凹部内壁面１３３，１３４に当接させ、上端縁２３ｕ，２４ｕを、抜け止め防止部１７２に係止させる。第一及び第二突出部２３，２４は、第一方向Ｘに沿って移動することが規制され、センサ２０Ｒ，２０Ｌともに取付板１５に取り付けた配置状態が確実に維持されている。第二実施形態では、センサ２０Ｌの取付操作時に、センサ２０Ｒの第一方向Ｘの移動が規制されて確実に取付板１５に取り付けられており、続いてセンサ２０Ｌの取り付け操作を行い易くなっている。また、各抜け止め防止部１７２の下端縁１７２ｄと突出部の上端縁２１ｕ，２３ｕ，２４ｕとが、直状に係止可能になっており、抜け止め防止効果に優れている。さらに、スナップフィット状の抜け止め防止部材を用いることによって、立ち上がり面１７２ａの立ち上がり角度の調節を容易に行える。よって、突出部の端縁部を係止する係止力の加減を、適宜に調節しやすい構成となっている。 Similarly, when the sensor 20L is mounted on the mounting plate 15, the sensor 20L can be mounted on the mounting plate 15 after the sensor 20R is securely mounted on the mounting plate 15. Similar to the sensor 20R, the lower end edges 23d and 24d of the first and second protrusions 23 and 24 are moved to the housing recess inner wall surface 133 of the base of the hook-shaped mounting portions 13 and 14 by an operation of sliding the sensor 20L. The upper end edges 23 u and 24 u are brought into contact with the stopper 134 and are locked to the retaining portion 172. The first and second protrusions 23 and 24 are restricted from moving in the first direction X, and the arrangement state in which both the sensors 20R and 20L are attached to the attachment plate 15 is reliably maintained. In the second embodiment, when the sensor 20L is attached, the movement of the sensor 20R in the first direction X is restricted so that the sensor 20L is reliably attached to the attachment plate 15, and subsequently the sensor 20L is easily attached. .. Further, the lower end edge 172d of each retaining portion 172 and the upper end edges 21u, 23u, 24u of the projecting portions can be directly engaged with each other, which is excellent in retaining prevention effect. Furthermore, by using the snap-fitting prevention member, the rising angle of the rising surface 172a can be easily adjusted. Therefore, the amount of locking force for locking the edge portion of the protruding portion can be easily adjusted appropriately.
