以下、本発明に係る組付け部材の組付け構造の実施の形態について、図面を参照しながら説明する。なお、以下の説明において、上述の従来例と同一の構成要素は、同一符号を付す。   Embodiments of an assembly structure for assembly members according to the present invention will be described below with reference to the drawings. In the following description, the same components as those in the conventional example are given the same reference numerals.

図１は、本発明に係る組付け部材の組付け構造の第１の実施形態を示すメータ装置全体の縦断側面図である。図１において、メータ装置は、被組付け部材としての、たとえばＰＰ（ポリプロピレン）樹脂の成形品からなるメータケース１の前部に、組付け部材としての、たとえばアクリル樹脂の成形品からなる表ガラス１０が取り付けられて構成される。メータケース１内には、指針５および文字板６を有する速度計等の計器が収納されている。   FIG. 1 is a longitudinal sectional side view of the entire meter device showing a first embodiment of the assembly structure of the assembly member according to the present invention. In FIG. 1, a meter device is a front glass made of, for example, an acrylic resin molded product as an assembly member at the front portion of a meter case 1 made of, for example, a molded product of PP (polypropylene) resin, as an assembled member. 10 is attached and comprised. In the meter case 1, a meter such as a speedometer having a pointer 5 and a dial 6 is accommodated.

メータケース１の端部には、係止孔８が形成された係止部７が複数個、一体形成されている。表ガラス１０の端部には、弾性を有する複数個の係止片１１が係止部７に対応して一体形成され、この係止片１１の先端には、爪部１２が形成されている。   A plurality of locking portions 7 each having a locking hole 8 are integrally formed at the end of the meter case 1. At the end portion of the front glass 10, a plurality of elastic locking pieces 11 are integrally formed corresponding to the locking portion 7, and a claw portion 12 is formed at the tip of the locking piece 11. .

図２は、係止部７と爪部１２の係合を説明する図であり、（Ａ）は係合前、（Ｂ）は係合後を示す。まず、係止部７の形状を説明すると、図２（Ａ）の拡大図に示すように、係止部７の係止孔８は、爪部１２が挿入される入口側が漏斗状に形成されると共に、その内面が漏斗状部分から出口側に向かって孔の大きさが次第に小さくなるテーパ面となっている。また、係止孔８の出口側の端面７ａの内周部分には、係止孔８の端面７ａと内面との間で直線的な斜面に形成された（つまり、「Ｃ面取り」と呼ばれる形状の）第１の面取り部としての面取り部１７が設けられている。すなわち、従来例の図５（Ｂ）では、テーパ面が出口側の端面まで続いていたが、図２では、テーパ面は、出口側の端面７ａまで続かずに端面７ａの少し手前までで終端し、その終端場所から面取り部１７が形成されているのである。   2A and 2B are diagrams for explaining the engagement between the locking portion 7 and the claw portion 12, wherein FIG. 2A shows before engagement, and FIG. 2B shows after engagement. First, the shape of the locking portion 7 will be described. As shown in the enlarged view of FIG. 2A, the locking hole 8 of the locking portion 7 is formed in a funnel shape on the inlet side where the claw portion 12 is inserted. In addition, the inner surface is a tapered surface that gradually decreases in size from the funnel-shaped portion toward the outlet side. Further, an inner peripheral portion of the end surface 7a on the outlet side of the locking hole 8 is formed on a linear slope between the end surface 7a and the inner surface of the locking hole 8 (that is, a shape called “C chamfering”). A chamfered portion 17 is provided as a first chamfered portion. That is, in FIG. 5B of the conventional example, the tapered surface continues to the end surface on the outlet side. However, in FIG. 2, the tapered surface does not continue to the end surface 7a on the outlet side, but ends just before the end surface 7a. The chamfered portion 17 is formed from the end location.

次に、爪部１２の形状を説明すると、爪部１２は、弾性を有する係止片１１の先端から延出形成されており、係止片１１の外面から直角に所定寸法だけ延出形成された平らな段部１６を有する。また、爪部１２は、その先端から段部１６の先端部分に向かってその大きさが次第に大きくなるように、テーパ面１２ａが形成されている。   Next, the shape of the claw portion 12 will be described. The claw portion 12 is formed to extend from the tip of the locking piece 11 having elasticity, and is formed to extend from the outer surface of the locking piece 11 by a predetermined dimension at a right angle. A flat step 16. Further, the claw portion 12 is formed with a tapered surface 12a so that the size thereof gradually increases from the tip end toward the tip end portion of the step portion 16.

次に、上述のような構造を有する係止部７と爪部１２の係合の仕方を説明する。まず、図２（Ａ）に示すように、メータケース１に設けられた係止部７の係止孔８上に、この係止孔８に対応して表ガラス１０に設けられた係止片１１の爪部１２が位置決めされる。係止片１１は、対応する係止孔８上に位置決めされたとき、係止孔８と整列する位置からわずかに外側の方に（すなわち、メータケース１から離れる方に）配置されるようになされている。   Next, how to engage the locking portion 7 and the claw portion 12 having the above-described structure will be described. First, as shown in FIG. 2 (A), on the locking hole 8 of the locking portion 7 provided on the meter case 1, the locking piece provided on the front glass 10 corresponding to the locking hole 8. Eleven claws 12 are positioned. When the locking piece 11 is positioned on the corresponding locking hole 8, the locking piece 11 is arranged slightly outward from the position aligned with the locking hole 8 (that is, away from the meter case 1). Has been made.

そこで、係止片１１が、組付け作業者によりその弾性に抗して横方向に押されて係止孔８上に整列させられ、爪部１２が係止孔８に挿入される。次に、係止片１１が押し下げられることによって、爪部１２は、段部１６の先端が係止片１１の弾性に起因して係止孔８のテーパ面と面取り部１７に接触しながら係止孔８の出口側に向かう。   Therefore, the locking piece 11 is pushed in the lateral direction against the elasticity by the assembly operator and aligned on the locking hole 8, and the claw portion 12 is inserted into the locking hole 8. Next, when the locking piece 11 is pushed down, the claw portion 12 is engaged while the tip of the stepped portion 16 is in contact with the tapered surface of the locking hole 8 and the chamfered portion 17 due to the elasticity of the locking piece 11. Head toward the exit side of the stop hole 8.

次いで、図２（Ｂ）に示すように、爪部１２の段部１６は、係止孔８の出口側に抜け、端面７ａに係合する。   Next, as shown in FIG. 2B, the stepped portion 16 of the claw portion 12 comes out to the exit side of the locking hole 8 and engages with the end surface 7a.

このようにして係止部７と爪部１２の係合が行われるが、爪部１２の段部が係合する係止孔８の端面７ａの内周部分が面取りされているため、係止孔８のテーパ面と面取り部１７とでなす角度が鈍角となるため爪部１２の段部１６の先端によって削られることがほとんどなくなり、削りくず（すなわち、異物）はほぼ発生しなくなる。したがって、削りくずがメータ内部に異物として混入することがほぼなくなる。   The engaging portion 7 and the claw portion 12 are engaged in this way, but the inner peripheral portion of the end surface 7a of the engaging hole 8 with which the step portion of the claw portion 12 engages is chamfered. Since the angle formed by the taper surface of the hole 8 and the chamfered portion 17 is an obtuse angle, it is hardly scraped by the tip end of the step portion 16 of the claw portion 12, and shavings (that is, foreign matter) are hardly generated. Therefore, the shavings are hardly mixed as foreign matter inside the meter.

次に、図３は、本発明に係る組付け部材の組付け構造の第２の実施形態を示すメータ装置全体の縦断側面図である。図３において、メータ装置は、被組付け部材としての、たとえばＰＰ樹脂の成形品からなるメータケース１の前部に、組付け部材としての、たとえばＡＢＳ樹脂の成形品かからなる見返し板１８が取り付けられている。メータケース１内には、指針５および文字板６を有する速度計等の計器が収納されている。   Next, FIG. 3 is a longitudinal side view of the entire meter device showing a second embodiment of the assembly structure of the assembly member according to the present invention. In FIG. 3, the meter device has a turn-back plate 18 made of, for example, a molded product of ABS resin as an assembled member at the front portion of the meter case 1 made of, for example, a molded product of PP resin. It is attached. In the meter case 1, a meter such as a speedometer having a pointer 5 and a dial 6 is accommodated.

メータケース１の端部には、係止孔８が形成された係止部７が複数個、一体形成されている。見返し板１８の端部には、弾性を有する複数個の係止片１１が係止部７に対応して形成され、この係止片１１の先端には、爪部１２が形成されている。   A plurality of locking portions 7 each having a locking hole 8 are integrally formed at the end of the meter case 1. A plurality of elastic locking pieces 11 are formed on the end portion of the facing plate 18 corresponding to the locking portions 7, and claw portions 12 are formed on the tips of the locking pieces 11.

図４は、係止部７と爪部１２の係合を説明する図であり、（Ａ）は係合前、（Ｂ）は係合後を示す。まず、係止部７の形状を説明すると、図２（Ａ）に示すように、係止部７の係止孔８は、爪部１２が挿入される入口側が漏斗状に形成されると共に、その内面が漏斗状部分から出口側に向かって孔の大きさが次第に小さくなるテーパ面となっている。   4A and 4B are diagrams for explaining the engagement between the locking portion 7 and the claw portion 12, in which FIG. 4A shows before engagement and FIG. 4B shows after engagement. First, the shape of the locking portion 7 will be described. As shown in FIG. 2A, the locking hole 8 of the locking portion 7 is formed in a funnel shape on the inlet side where the claw portion 12 is inserted. The inner surface is a tapered surface in which the size of the hole gradually decreases from the funnel-shaped portion toward the outlet side.

次に、爪部１２の形状を説明すると、爪部１２は、弾性を有する係止片１１の先端から延出形成されており、係止片１１の外面から直角に所定寸法だけ延出形成された平らな段部１６を有する。また、爪部１２は、その先端から段部１６に向かってその大きさが次第に大きくなるように、テーパ面１２ａが形成されている。また、テーパ面１２ａと段部１６の先端部分との間で曲線な斜面に形成された（つまり、「Ｒ面取り」と呼ばれる形状の）第２の面取り部としての面取り部１９が設けられている。すなわち、従来例の図５（Ｂ）では、段部１６の先端部分は直角になるように突出していたが、図４では、テーパ面１２と段部１６の間で鋭角的な角は形成されず、面取り部１９が形成されているのである。   Next, the shape of the claw portion 12 will be described. The claw portion 12 is formed to extend from the tip of the locking piece 11 having elasticity, and is formed to extend from the outer surface of the locking piece 11 by a predetermined dimension at a right angle. A flat step 16. Further, the claw portion 12 is formed with a tapered surface 12a so that the size thereof gradually increases from the tip toward the step portion 16. Further, a chamfered portion 19 is provided as a second chamfered portion formed in a curved slope between the tapered surface 12a and the tip portion of the step portion 16 (that is, a shape called “R chamfer”). . That is, in FIG. 5B of the conventional example, the tip portion of the step portion 16 protrudes at a right angle, but in FIG. 4, an acute angle is formed between the tapered surface 12 and the step portion 16. Instead, the chamfered portion 19 is formed.

次に、上述のような構造を有する係止部７と爪部１２の係合の仕方を説明する。まず、図４（Ａ）に示すように、メータケース１に設けられた係止部７の係止孔８上に、この係止孔８に対応して表ガラス１０に設けられた係止片１１の爪部１２が位置決めされる。係止片１１は、対応する係止孔８上に位置決めされたとき、係止孔８と整列する位置からわずかに外側の方に（すなわち、メータケース１から離れる方に）配置されるようになされている。   Next, how to engage the locking portion 7 and the claw portion 12 having the above-described structure will be described. First, as shown in FIG. 4 (A), on the locking hole 8 of the locking portion 7 provided on the meter case 1, the locking piece provided on the front glass 10 corresponding to the locking hole 8. Eleven claws 12 are positioned. When the locking piece 11 is positioned on the corresponding locking hole 8, the locking piece 11 is arranged slightly outward from the position aligned with the locking hole 8 (that is, away from the meter case 1). Has been made.

そこで、係止片１１が、組付け作業者によりその弾性に抗して横方向に押されて係止孔８上に整列させられ、爪部１２が係止孔８に挿入される。次に、係止片１１が押し下げられることによって、爪部１２は、面取り部１９が係止片１１の弾性に起因して係止孔８のテーパ面に接触しながら係止孔８の出口側に向かう。   Therefore, the locking piece 11 is pushed in the lateral direction against the elasticity by the assembly operator and aligned on the locking hole 8, and the claw portion 12 is inserted into the locking hole 8. Next, when the locking piece 11 is pushed down, the claw portion 12 causes the chamfered portion 19 to come into contact with the taper surface of the locking hole 8 due to the elasticity of the locking piece 11. Head for.

次いで、図４（Ｂ）に示すように、爪部１２の段部１６は、係止孔８の出口側に抜け、端面７ａに係合する。   Next, as shown in FIG. 4B, the stepped portion 16 of the claw portion 12 comes out to the exit side of the locking hole 8 and engages with the end surface 7a.

このようにして係止部７と爪部１２の係合が行われるが、爪部１２の段部１６の先端部分が鋭角な角にならないように、面取り部１９が形成されているため、係止孔８の端面７ａの内周部分が削られることがほとんどなくなり、削りくず（すなわち、異物）はほぼ発生しなくなる。したがって、削りくずがメータ内部に異物として混入することがほぼなくなる。   In this way, the engaging portion 7 and the claw portion 12 are engaged, but the chamfered portion 19 is formed so that the tip end portion of the step portion 16 of the claw portion 12 does not have an acute angle. The inner peripheral portion of the end surface 7a of the stop hole 8 is hardly scraped, and shavings (that is, foreign matter) are hardly generated. Therefore, the shavings are hardly mixed as foreign matter inside the meter.

また、上述の第２の実施形態では、爪部１２の段部１６とテーパ面１２ａの間に面取り部１９が形成されているが、これに代えて、段部１６の平らな部分をなくし、係止片１１の外面１１ａから直接大きな曲面状の面取り部１９を形成しても良い。   Further, in the second embodiment described above, the chamfered portion 19 is formed between the stepped portion 16 of the claw portion 12 and the tapered surface 12a. Instead, the flat portion of the stepped portion 16 is eliminated, A large curved chamfer 19 may be formed directly from the outer surface 11 a of the locking piece 11.

また、上述の第１および第２の実施形態の組付け構造を組み合わせて適用しても良い。すなわち、係止孔８の端面７ａの内周部分に面取り部１７を形成すると共に、爪部１２の段部１６の先端部分に面取り部１９を形成するように構成しても良い。   Moreover, you may apply combining the assembly structure of the above-mentioned 1st and 2nd embodiment. That is, the chamfered portion 17 may be formed at the inner peripheral portion of the end surface 7 a of the locking hole 8, and the chamfered portion 19 may be formed at the tip portion of the step portion 16 of the claw portion 12.

また、本発明は、上述の実施の形態では、メータケース１と表ガラス１０または見返し板１８との組付けについて説明したが、これに限らず見返し板１８と表ガラス１０の組付けにも適用することができる。   In the above-described embodiment, the present invention has been described with respect to the assembly of the meter case 1 and the front glass 10 or the facing plate 18. However, the present invention is not limited to this and is also applicable to the assembly of the facing plate 18 and the facing glass 10. can do.

さらに、本発明は、メータ装置に限らず、一般的に、被組付け部材と組付け部材間の組付けを係止部の係止孔と爪部の係合により行う際に適用可能である。   Further, the present invention is not limited to the meter device, and is generally applicable when the assembly between the assembly target member and the assembly member is performed by the engagement of the locking hole of the locking portion and the claw portion. .
