Description

本発明は、互いに組み付けられる複数の樹脂体を備える樹脂構造体に関する。 The present invention relates to a resin structure including a plurality of resin bodies that are assembled to each other.

従来から、車両に搭載される電気接続箱（例えば、リレーボックス）等のように、複数の樹脂体を互いに組み付けて構成される樹脂構造体が提案されている。例えば、従来の電気接続箱の一つは、電子部品などを保持する樹脂製のブロック部と、そのブロック部が内部に挿入されて組み付けられる樹脂製のフレーム部と、を有している（例えば、特許文献１を参照。）。 Conventionally, a resin structure having a plurality of resin bodies assembled with each other, such as an electric connection box (for example, a relay box) mounted on a vehicle, has been proposed. For example, one of the conventional electrical connection boxes has a resin block portion for holding an electronic component or the like, and a resin frame portion into which the block portion is inserted and assembled (for example). , Patent Document 1).

上述した従来の樹脂構造体では、ブロック部の外壁に設けられているロック部と、フレーム部の内壁に設けられている被ロック部と、が互いに係合することで、ブロック部とフレーム部とが組み付けられるようになっている。しかし、この樹脂構造体では、ブロック部及びフレーム部の製造公差や、それらを構成する樹脂材料の違いによる膨張収縮の度合いの相違等に起因し、ブロック部をフレーム部に組み付ける作業が困難になる場合がある。また、同様の原因から、フレーム部の内部におけるブロック部の位置ズレ（いわゆるガタつき）が生じる場合もある。換言すると、ブロック部とフレーム部との組み付け性が損なわれる場合がある。 In the conventional resin structure described above, the lock portion provided on the outer wall of the block portion and the locked portion provided on the inner wall of the frame portion engage with each other to form the block portion and the frame portion. Is designed to be assembled. However, in this resin structure, the work of assembling the block portion to the frame portion becomes difficult due to the manufacturing tolerance of the block portion and the frame portion and the difference in the degree of expansion and contraction due to the difference in the resin materials constituting them. In some cases. Further, due to the same cause, the position of the block portion inside the frame portion may be displaced (so-called rattling). In other words, the assembling property between the block portion and the frame portion may be impaired.

本発明の目的の一つは、複数の樹脂体同士の組み付け性に優れた樹脂構造体の提供である。 One of the objects of the present invention is to provide a resin structure having excellent assembling property between a plurality of resin bodies.

［２］
上記［１］に記載の樹脂構造体において、
前記受け部は、
前記当て面の周縁の少なくとも一部から前記挿入方向に延びる壁部を、更に有する、
樹脂構造体であること。 In order to achieve the above-mentioned object, the resin structure according to the present invention is characterized by the following [1] to [2].
[1]
A resin structure comprising a first resin body and a second resin body having an assembly region inside in which the first resin body is inserted and assembled.
The first resin body is
It has a locking portion that engages with the locked portion of the second resin body, and a regulating portion that regulates the relative position of the first resin body with respect to the second resin body in the assembly region.
The regulatory department
It has a plate-shaped portion that protrudes toward the inner wall of the second resin body that defines the assembly region and extends in the insertion direction, and a protruding portion that protrudes from the plate-shaped portion in a direction intersecting the insertion direction. death,
The second resin body is
The inner wall has a groove-shaped receiving portion extending in the insertion direction so as to receive the restricting portion.
The receiving part is
It has a groove structure in which a first groove portion extending so as to sandwich the plate-shaped portion and a second groove portion extending so as to sandwich the protrusion portion are communicated with each other, and is outside the second groove portion and at the groove entrance of the second groove portion. It has a contact surface that is located on the inner side in the insertion direction and spreads in a direction intersecting the insertion direction.
Must be a resin structure.
[2]
In the resin structure according to the above [1],
The receiving part is
Further having a wall portion extending in the insertion direction from at least a part of the peripheral edge of the contact surface.
Must be a resin structure.

上記［１］の構成の樹脂構造体によれば、第１樹脂体と第２樹脂体との組み付けの際、第１樹脂体のロック部と第２樹脂体の被ロック部とが係合するとともに、第１樹脂体の規制部が第２樹脂体の受け部に挿入されながら受け入れられる。このとき、規制部が受け部に案内されることで組み付けの作業が容易になる。更に、規制部の板状部が受け部の第１溝部に挟まれ、且つ、規制部の突出部が受け部の第２溝部に挟まれることで、受け部に対する規制部の位置ズレ（即ち、組付領域内での第２樹脂体に対する第１樹脂体の相対位置のズレ。いわゆるガタつき）が抑制される。加えて、仮に、組み付けの際に規制部が受け部に適正に挿入されなかった場合、規制部の突出部が当て面に突き当たることで、規制部が受け部に適正に挿入されていないことを作業者等が容易に認識できる。また、受け部の溝入口よりも奥側に当て面が設けられることで、溝入口と当て面とを作業者等が目視で容易に区別できる。したがって、本構成の樹脂構造体は、従来の樹脂構造体に比べ、複数の樹脂体同士の組み付け性に優れる。 According to the resin structure having the configuration of [1] above, when the first resin body and the second resin body are assembled, the locked portion of the first resin body and the locked portion of the second resin body are engaged with each other. At the same time, the regulating portion of the first resin body is accepted while being inserted into the receiving portion of the second resin body. At this time, the assembly work becomes easy because the regulation part is guided to the receiving part. Further, the plate-shaped portion of the regulating portion is sandwiched between the first groove portions of the receiving portion, and the protruding portion of the regulating portion is sandwiched between the second groove portions of the receiving portion, so that the position of the regulating portion is displaced with respect to the receiving portion (that is,). Misalignment of the relative position of the first resin body with respect to the second resin body in the assembly region, so-called rattling) is suppressed. In addition, if the regulating part is not properly inserted into the receiving part during assembly, the protruding part of the regulating part hits the contact surface, so that the regulating part is not properly inserted into the receiving part. Workers can easily recognize it. Further, since the contact surface is provided on the back side of the groove entrance of the receiving portion, the operator or the like can easily visually distinguish between the groove entrance and the contact surface. Therefore, the resin structure having this configuration is superior in assembling property between a plurality of resin bodies as compared with the conventional resin structure.

上記［２］の構成の樹脂構造体によれば、当て面の周縁から延びる壁部が、当て面の少なくとも一部を囲んだ状態となる。これにより、規制部が受け部に適正に挿入されなかった場合、当て面に突き当たった突出部が、当て面に沿って滑るように移動したとしても、当て面の外にまで移動する（例えば、当て面から脱落する）ことが抑制される。よって、本構成の樹脂構造体は、規制部が受け部に適正に挿入されているか否かを、作業者等が更に容易かつ確実に認識できる。 According to the resin structure having the configuration of [2] above, the wall portion extending from the peripheral edge of the contact surface surrounds at least a part of the contact surface. As a result, if the regulating portion is not properly inserted into the receiving portion, the protruding portion that hits the contact surface moves out of the contact surface even if it slides along the contact surface (for example,). (Drop off from the contact surface) is suppressed. Therefore, in the resin structure of this configuration, the operator or the like can more easily and surely recognize whether or not the regulating portion is properly inserted into the receiving portion.

このように、本発明によれば、複数の樹脂体同士の組み付け性に優れる樹脂構造体を提供できる。 As described above, according to the present invention, it is possible to provide a resin structure having excellent assembling property between a plurality of resin bodies.

＜実施形態＞
以下、図面を参照しながら、図１に示す本発明の実施形態に係る樹脂構造体１について説明する。樹脂構造体１は、典型的には、車両に搭載され、リレー等の電子部品を収容するリレーボックス（電気接続箱）である。 <Embodiment>
Hereinafter, the resin structure 1 according to the embodiment of the present invention shown in FIG. 1 will be described with reference to the drawings. The resin structure 1 is typically a relay box (electrical connection box) mounted on a vehicle and accommodating electronic components such as relays.

図１及び図２に示すように、樹脂構造体１は、筒状のフレーム部２と、フレーム部２の内部に組み付けられるブロック部３と、を含んで構成される。フレーム部２及びブロック部３の各々は、樹脂成形体である。フレーム部２は、本発明の「第２樹脂体」に対応し、ブロック部３は、本発明の「第１樹脂体」に対応している。 As shown in FIGS. 1 and 2, the resin structure 1 includes a cylindrical frame portion 2 and a block portion 3 assembled inside the frame portion 2. Each of the frame portion 2 and the block portion 3 is a resin molded body. The frame portion 2 corresponds to the "second resin body" of the present invention, and the block portion 3 corresponds to the "first resin body" of the present invention.

以下、説明の便宜上、図１、図３～図５に示すように、「上下方向」、「周方向」、「内外方向」、「上」、「下」、「内」及び「外」を定義する。「上下方向」、「周方向」及び「内外方向」は、互いに直交している。樹脂構造体１の車両搭載時において、「上下方向」は、車両の上下方向に対応している。「周方向」は、フレーム部２の後述する周壁１１の周方向に対応し、「内外方向」は、周壁１１の厚み方向に対応している。以下、樹脂構造体１を構成する各部材について順に説明する。 Hereinafter, for convenience of explanation, as shown in FIGS. 1, 3 to 5, "vertical direction", "circumferential direction", "inside / outside direction", "top", "bottom", "inside" and "outside" are used. Define. The "vertical direction", "circumferential direction" and "inner / outer direction" are orthogonal to each other. When the resin structure 1 is mounted on the vehicle, the "vertical direction" corresponds to the vertical direction of the vehicle. The "circumferential direction" corresponds to the circumferential direction of the peripheral wall 11 described later of the frame portion 2, and the "inner / outer direction" corresponds to the thickness direction of the peripheral wall 11. Hereinafter, each member constituting the resin structure 1 will be described in order.

まず、フレーム部２について説明する。フレーム部２は、図１及び図２に示すように、上下方向に延びる略矩形筒状の周壁１１を有する。周壁１１の内部には、図２（ｂ）に示すように、隔壁１２が設けられている。隔壁１２は、上下方向に延び、且つ、複数箇所（本例では、２箇所）で屈曲しながら周壁１１の内部空間を横断するように延びて、周壁１１の内部空間を二分している。隔壁１２によって二分された２つの内部空間のうち一方側の空間（即ち、隔壁１２と周壁１１の周方向の一部分とで囲まれ且つ上下方向に延びる空間）は、ブロック部３が組み付けられる組付領域Ｒを画成している（図２（ｂ）参照）。ブロック部３は、下側から、フレーム部２の組付領域Ｒに組み付けられることになる。 First, the frame portion 2 will be described. As shown in FIGS. 1 and 2, the frame portion 2 has a substantially rectangular tubular peripheral wall 11 extending in the vertical direction. As shown in FIG. 2B, a partition wall 12 is provided inside the peripheral wall 11. The partition wall 12 extends in the vertical direction and extends so as to cross the internal space of the peripheral wall 11 while bending at a plurality of locations (two locations in this example) to divide the internal space of the peripheral wall 11 into two. The space on one side of the two internal spaces divided by the partition wall 12 (that is, the space surrounded by the partition wall 12 and a part of the peripheral wall 11 in the circumferential direction and extending in the vertical direction) is assembled to which the block portion 3 is assembled. The area R is defined (see FIG. 2B). The block portion 3 will be assembled to the assembly region R of the frame portion 2 from the lower side.

図２（ｂ）に示すように、組付領域Ｒに面する隔壁１２の側面における複数箇所（本例では、２箇所）にはそれぞれ、被ロック部１３が設けられている。組付領域Ｒに面する周壁１１の内壁面の１箇所には、受け部２６が設けられている。フレーム部２とブロック部３との組付時、被ロック部１３は、ブロック部３の後述するロック部３３と係合することになり、受け部２６には、ブロック部３の後述する規制部３４が挿入されて受け入れられることになる。 As shown in FIG. 2B, locked portions 13 are provided at a plurality of locations (two locations in this example) on the side surface of the partition wall 12 facing the assembly region R. A receiving portion 26 is provided at one location on the inner wall surface of the peripheral wall 11 facing the assembly region R. When the frame portion 2 and the block portion 3 are assembled, the locked portion 13 engages with the lock portion 33 described later in the block portion 3, and the receiving portion 26 has a restricting portion described later in the block portion 3. 34 will be inserted and accepted.

以下、図３（ａ）を参照しながら、受け部２６について説明する。図３（ａ）では、構造を理解し易くするため、樹脂構造体１が上下逆向きに示されている（図３（ｂ）、図４（ｂ）及び図５も同様）。 Hereinafter, the receiving portion 26 will be described with reference to FIG. 3A. In FIG. 3A, the resin structure 1 is shown upside down in order to make the structure easier to understand (the same applies to FIGS. 3B, 4B, and 5).

受け部２６は、周方向に所定距離だけ離れて周壁１１の内壁面から内側に突出し且つ上下方向に平行に延びる一対の略直方体状の突条部１４によって画成されている。一対の突条部１４の間には、上下方向に延びる第１溝部１７が画成されている。第１溝部１７は、上下双方に開口している。第１溝部１７に、ブロック部３の後述する規制部３４の板状部３５が挿入されることになる（図３（ｂ）等参照）。 The receiving portion 26 is defined by a pair of substantially rectangular parallelepiped ridge portions 14 projecting inward from the inner wall surface of the peripheral wall 11 and extending in parallel in the vertical direction at a distance of a predetermined distance in the circumferential direction. A first groove portion 17 extending in the vertical direction is defined between the pair of ridge portions 14. The first groove portion 17 is open on both the upper and lower sides. The plate-shaped portion 35 of the restricting portion 34 described later of the block portion 3 is inserted into the first groove portion 17 (see FIG. 3 (b) and the like).

各突条部１４は、周壁１１の内壁面に連続し且つ上下方向に延びる略直方体状の第１部分１５と、第１部分１５の内側に連続し且つ上下方向に延びる略直方体状の第２部分１６と、で構成されている。第２部分１６の下端面は、第１部分１５の下端面より上側（ブロック部３の挿入方向において奥側）に位置している。換言すれば、各突条部１４は、段付きの下端面を有する略直方体状の形状を有している。 Each ridge portion 14 has a substantially rectangular parallelepiped first portion 15 continuous with the inner wall surface of the peripheral wall 11 and extending in the vertical direction, and a substantially rectangular parallelepiped second portion continuous with the inside of the first portion 15 and extending in the vertical direction. It is composed of a portion 16. The lower end surface of the second portion 16 is located above the lower end surface of the first portion 15 (back side in the insertion direction of the block portion 3). In other words, each ridge portion 14 has a substantially rectangular parallelepiped shape having a stepped lower end surface.

一対の第１部分１５における周方向内側の側面（第１溝部１７に面する側面）には、周方向外側に窪み且つ上下方向に延びる一対の第２溝部１８が形成されている。各第２溝部１８の外側の溝側面は、周壁１１の内壁面の一部で構成されている。各第２溝部１８は、下方に開口する一方で、上方が上面１９（図４（ｂ）も参照）によって閉塞されている。一対の第２溝部１８は、第１溝部１７と連通している。一対の第２溝部１８に、ブロック部３の後述する規制部３４の突出部３６が挿入されることになる（図３（ｂ）等参照）。第１溝部１７及び一対の第２溝部１８は、上下方向からみて、Ｔ字状の溝部を構成している。ここで、第１溝部１７及び一対の第２溝部１８が、受け部２６を構成している。以上、受け部２６について説明した。 A pair of second groove portions 18 that are recessed outward in the circumferential direction and extend in the vertical direction are formed on the inner side surfaces (side surfaces facing the first groove portion 17) of the pair of first portions 15 in the circumferential direction. The outer groove side surface of each second groove portion 18 is formed of a part of the inner wall surface of the peripheral wall 11. Each second groove 18 opens downward, while the upper surface is closed by an upper surface 19 (see also FIG. 4B). The pair of second groove portions 18 communicate with the first groove portion 17. The protruding portion 36 of the restricting portion 34, which will be described later, of the block portion 3 will be inserted into the pair of second groove portions 18 (see FIG. 3 (b) and the like). The first groove portion 17 and the pair of second groove portions 18 form a T-shaped groove portion when viewed from the vertical direction. Here, the first groove portion 17 and the pair of second groove portions 18 form the receiving portion 26. The receiving portion 26 has been described above.

図３（ｂ）に示すように、一対の第２部分１６の下面には、上方に窪み且つ周方向内側に開口する（即ち、第１溝部１７に連通する）一対の矩形状の凹部２１が形成されている。各凹部２１を囲う溝側面は、Ｌ字状の囲み壁２３と、第１部分１５の内側端面の一部と、で構成されている。各凹部２１の溝底面（上面）は、当て面２２を構成している。当て面２２が設けられたことによる作用については後述する。囲み壁２３は、当て面２２の周方向に延びる内側の縁部及び内外方向に延びる周方向外側の縁部から下方に突出するＬ字状の壁である。 As shown in FIG. 3B, a pair of rectangular recesses 21 that are recessed upward and open inward in the circumferential direction (that is, communicate with the first groove portion 17) are formed on the lower surface of the pair of second portions 16. It is formed. The side surface of the groove surrounding each recess 21 is composed of an L-shaped surrounding wall 23 and a part of the inner end surface of the first portion 15. The bottom surface (upper surface) of the groove of each recess 21 constitutes a contact surface 22. The action due to the provision of the contact surface 22 will be described later. The surrounding wall 23 is an L-shaped wall that protrudes downward from the inner edge portion extending in the circumferential direction of the contact surface 22 and the outer edge portion in the circumferential direction extending in the inner / outer direction.

当て面２２は、第２溝部１８の上面１９よりも下側（ブロック部３の挿入方向において手前側）に位置し、且つ、第２溝部１８の下方開口よりも上側（ブロック部３の挿入方向において奥側）に位置している。図４から理解できるように、一対の当て面２２の周方向外側端縁同士の周方向の間隔は、一対の第２溝部１８の溝底面同士の周方向の間隔より広い。このように、一対の当て面２２と一対の第２溝部１８の下方開口との間で、上下方向の位置及び周方向の端部同士の間隔に差を設けることで、一対の当て面２２と一対の第２溝部１８の下方開口とを、作業者が目視で区別し易くなる。 The contact surface 22 is located below the upper surface 19 of the second groove portion 18 (front side in the insertion direction of the block portion 3) and above the lower opening of the second groove portion 18 (insertion direction of the block portion 3). It is located on the back side). As can be understood from FIG. 4, the circumferential distance between the circumferential outer edges of the pair of contact surfaces 22 is wider than the circumferential distance between the groove bottom surfaces of the pair of second groove portions 18. In this way, by providing a difference in the position in the vertical direction and the distance between the end portions in the circumferential direction between the pair of contact surfaces 22 and the lower opening of the pair of second groove portions 18, the pair of contact surfaces 22 and the lower openings are provided. It is easy for the operator to visually distinguish the lower opening of the pair of second groove portions 18.

図３（ｂ）に示すように、一対の突条部１４の間に位置する（即ち、第１溝部１７に面する）周壁１１の内壁面には、内側に突出し且つ上下方向に延びるリブ２４が形成されている。更に、一対の第２部分１６の内側端面にはそれぞれ、内側に突出し且つ上下方向に延びるリブ２５が形成されている。リブ２４及び一対のリブ２５が設けられたことによる作用については後述する。 As shown in FIG. 3 (b), the inner wall surface of the peripheral wall 11 located between the pair of ridges 14 (that is, facing the first groove 17) has ribs 24 protruding inward and extending in the vertical direction. Is formed. Further, each of the inner end faces of the pair of second portions 16 is formed with ribs 25 that project inward and extend in the vertical direction. The operation due to the provision of the rib 24 and the pair of ribs 25 will be described later.

次いで、ブロック部３について説明する。ブロック部３は、図１及ぶ図２に示すように、上下方向に延び且つフレーム部２の組付領域Ｒの輪郭形状に対応する輪郭形状を有する外周壁３１を有している。このため、ブロック部３は、下側から、フレーム部２の組付領域Ｒに組み付け可能となっている。 Next, the block portion 3 will be described. As shown in FIGS. 1 and 2, the block portion 3 has an outer peripheral wall 31 that extends in the vertical direction and has a contour shape corresponding to the contour shape of the assembly region R of the frame portion 2. Therefore, the block portion 3 can be assembled to the assembly region R of the frame portion 2 from the lower side.

ブロック部３の上面には、図１に示すように、上方に開口する多数の保持部３２が形成されている。多数の保持部３２には、電子部品などが保持される。ブロック部３の外周壁３１には、フレーム部２の複数の被ロック部１３に対応して、周方向の複数箇所（本例では、２箇所）にて、ロック部３３がそれぞれ設けられている。 As shown in FIG. 1, a large number of holding portions 32 that open upward are formed on the upper surface of the block portion 3. Electronic components and the like are held in a large number of holding portions 32. The outer peripheral wall 31 of the block portion 3 is provided with lock portions 33 at a plurality of locations in the circumferential direction (two locations in this example) corresponding to the plurality of locked portions 13 of the frame portion 2. ..

ブロック部３の外周壁３１には、フレーム部２の受け部２６に対応して、規制部３４が設けられている。規制部３４は、図３（ａ）及び図４に示すように、外周壁３１から外側に突出し且つ上下方向に延びる板状部３５と、板状部３５の突出端部（外側端部）から周方向両側に突出し且つ上下方向に延びる突出部３６と、で構成される。よって、規制部３４は、上下方向からみて、Ｔ字状の形状を有している。以上、樹脂構造体１を構成する各部材について説明した。 The outer peripheral wall 31 of the block portion 3 is provided with a regulating portion 34 corresponding to the receiving portion 26 of the frame portion 2. As shown in FIGS. 3A and 4, the restricting portion 34 extends from the outer peripheral wall 31 to the outside and extends in the vertical direction from the plate-shaped portion 35 and the protruding end portion (outer end portion) of the plate-shaped portion 35. It is composed of a protruding portion 36 that protrudes on both sides in the circumferential direction and extends in the vertical direction. Therefore, the regulating unit 34 has a T-shaped shape when viewed from the vertical direction. The members constituting the resin structure 1 have been described above.

次いで、フレーム部２とブロック部３との正規の組み付けについて説明する。フレーム部２とブロック部３とを正規に組み付けるためには、図１に示すように、多数の電子部品などが多数の保持部３２に保持されたブロック部３が、フレーム部２の下方に位置するように、フレーム部２及びブロック部３を配置する。なお、電子部品などの保持部３２への保持は、ブロック部３がフレーム部２に組付けられた後に行われてもよい。 Next, the regular assembly of the frame portion 2 and the block portion 3 will be described. In order to properly assemble the frame portion 2 and the block portion 3, as shown in FIG. 1, the block portion 3 in which a large number of electronic components and the like are held by a large number of holding portions 32 is located below the frame portion 2. The frame portion 2 and the block portion 3 are arranged so as to do so. It should be noted that the holding of the electronic component or the like in the holding portion 32 may be performed after the block portion 3 is assembled to the frame portion 2.

次いで、フレーム部２に対して、ブロック部３を下側から近づけて、フレーム部２の組付領域Ｒにブロック部３を挿入する。この挿入は、ブロック部３の規制部３４がフレーム部２の受け部２６に挿入されるように、進行していく。より具体的には、規制部３４の板状部３５が第１溝部１７に挿入され、規制部３４の突出部３６が一対の第２溝部１８に挿入されていく（図３（ｂ）及び図４（ａ）参照）。これにより、規制部３４が受け部２６に案内されることで、組み付けの作業が容易になる。 Next, the block portion 3 is brought closer to the frame portion 2 from below, and the block portion 3 is inserted into the assembly region R of the frame portion 2. This insertion proceeds so that the regulating portion 34 of the block portion 3 is inserted into the receiving portion 26 of the frame portion 2. More specifically, the plate-shaped portion 35 of the regulating portion 34 is inserted into the first groove portion 17, and the protruding portion 36 of the regulating portion 34 is inserted into the pair of second groove portions 18 (FIGS. 3 (b) and FIG. 4 (a)). As a result, the regulating unit 34 is guided to the receiving unit 26, which facilitates the assembling work.

この挿入は、図４（ｂ）に示すように、規制部３４の突出部３６の上端面（ブロック部３の挿入方向において奥側の端面）が、一対の第２溝部１８の上面１９に当接するまで継続される。規制部３４の突出部３６の上端面が一対の第２溝部１８の上面１９に当接すると、ブロック部３の複数のロック部３３とフレーム部２の複数の被ロック部１３とがそれぞれ係合すると共に、フレーム部２とブロック部３との組み付けが完了する。 In this insertion, as shown in FIG. 4B, the upper end surface of the protruding portion 36 of the regulating portion 34 (the end surface on the inner side in the insertion direction of the block portion 3) hits the upper surface 19 of the pair of second groove portions 18. It will continue until it touches. When the upper end surface of the protruding portion 36 of the regulating portion 34 comes into contact with the upper surface 19 of the pair of second groove portions 18, the plurality of locked portions 33 of the block portion 3 and the plurality of locked portions 13 of the frame portion 2 are engaged with each other. At the same time, the assembly of the frame portion 2 and the block portion 3 is completed.

フレーム部２とブロック部３との組付完了状態（図３（ｂ）及び図４参照）では、複数のロック部３３と複数の被ロック部１３とがそれぞれ係合していることで、フレーム部２とブロック部３との上下方向への分離が防止される。更に、ブロック部３の規制部３４が、フレーム部２の受け部２６に受け入れられていることで（図４（ａ）参照）、規制部３４の板状部３５が受け部２６の第１溝部１７に挟まれ、且つ、規制部３４の突出部３６が受け部２６の一対の第２溝部１８に挟まれる。これにより、受け部２６に対する規制部３４の周方向及び内外方向の相対移動（即ち、位置ズレ。ガタつき）が抑制される。 In the assembled state of the frame portion 2 and the block portion 3 (see FIGS. 3B and 4), the plurality of locked portions 33 and the plurality of locked portions 13 are engaged with each other, whereby the frame is framed. Separation of the portion 2 and the block portion 3 in the vertical direction is prevented. Further, since the regulating portion 34 of the block portion 3 is received by the receiving portion 26 of the frame portion 2 (see FIG. 4A), the plate-shaped portion 35 of the regulating portion 34 becomes the first groove portion of the receiving portion 26. It is sandwiched between 17 and the protruding portion 36 of the regulating portion 34 is sandwiched between the pair of second groove portions 18 of the receiving portion 26. As a result, relative movement (that is, positional deviation, rattling) of the restricting portion 34 with respect to the receiving portion 26 in the circumferential direction and the inward / outward direction is suppressed.

更に、図４（ａ）に示すように、リブ２４が規制部３４（突出部３６）の外側端面と当接し、一対のリブ２５がブロック部３の外周壁３１と当接している。これにより、受け部２６に対する規制部３４の内外方向の位置ズレ（ガタつき）がより一層抑制される。以上、フレーム部２とブロック部３との正規の組み付けについて説明した。 Further, as shown in FIG. 4A, the rib 24 is in contact with the outer end surface of the regulating portion 34 (protruding portion 36), and the pair of ribs 25 is in contact with the outer peripheral wall 31 of the block portion 3. As a result, the positional deviation (rattling) of the regulating portion 34 with respect to the receiving portion 26 in the inward and outward directions is further suppressed. The regular assembly of the frame portion 2 and the block portion 3 has been described above.

以下、フレーム部２に対するブロック部３の誤組付が生じた状態について説明する。本例では、ブロック部３を下側から、フレーム部２の組付領域Ｒに挿入する際、図５に示すように、ブロック部３の規制部３４の突出部３６全体（又は、突出部３６の周方向の一方側の端部）が、フレーム部２の受け部２６の一対の第２溝部１８に対して、相対的に内側に位置ズレする場合が発生し得る。 Hereinafter, a state in which the block portion 3 is erroneously assembled with respect to the frame portion 2 will be described. In this example, when the block portion 3 is inserted into the assembly region R of the frame portion 2 from the lower side, as shown in FIG. 5, the entire protruding portion 36 (or the protruding portion 36) of the regulating portion 34 of the block portion 3 is inserted. The end portion on one side in the circumferential direction of the frame portion 2 may be displaced inward relative to the pair of second groove portions 18 of the receiving portion 26 of the frame portion 2.

この場合、突出部３６が一対の第２溝部１８に正規に挿入されず、図５に示すように、突出部３６が、当て面２２に突き当たることになる。上述したように、当て面２２は、第２溝部１８の上面１９よりも下側（ブロック部３の挿入方向において手前側）に位置している。よって、正規の挿入の場合と比べて早期の段階（挿入が浅い段階）で挿入が停止させられることで、挿入が不適正であることを作業者等が容易に認識できる。 In this case, the protruding portion 36 is not normally inserted into the pair of second groove portions 18, and the protruding portion 36 abuts on the contact surface 22 as shown in FIG. As described above, the contact surface 22 is located below the upper surface 19 of the second groove portion 18 (front side in the insertion direction of the block portion 3). Therefore, since the insertion is stopped at an earlier stage (the stage where the insertion is shallow) as compared with the case of the regular insertion, the operator or the like can easily recognize that the insertion is inappropriate.

更に、当て面２２の縁部が囲み壁２３によって囲まれている。このため、当て面２２に突き当たった突出部３６が、当て面２２に沿って周方向又は内側に滑るように移動したとしても、突出部３６が囲み壁２３に当接することで、突出部３６が当て面２２の外にまで移動する（即ち、当て面２２から逃げる）ことが抑制される。このため、突出部３６が当て面２２から逃げることで、ブロック部３の更なる奥側への挿入が開始される事態が発生し難くなり、挿入が不適正であることを作業者等が容易かつより確実に認識できる。 Further, the edge portion of the contact surface 22 is surrounded by the surrounding wall 23. Therefore, even if the protruding portion 36 that abuts on the contact surface 22 slides in the circumferential direction or inward along the contact surface 22, the protruding portion 36 comes into contact with the surrounding wall 23, so that the protruding portion 36 is formed. Movement to the outside of the contact surface 22 (that is, escape from the contact surface 22) is suppressed. For this reason, when the protruding portion 36 escapes from the contact surface 22, it is less likely that the block portion 3 is further inserted into the inner side, and it is easy for the operator or the like to confirm that the insertion is improper. And it can be recognized more reliably.

＜作用・効果＞
以上より、本実施形態に係る樹脂構造体１によれば、フレーム部２とブロック部３の組み付けの際、ブロック部３のロック部３３とフレーム部２の被ロック部１３とが係合するとともに、ブロック部３の規制部３４がフレーム部２の受け部２６に挿入されて受け入れられる。そして、規制部３４の板状部３５が受け部２６の第１溝部１７に挟まれ、且つ、規制部３４の突出部３６が受け部２６の第２溝部１８に挟まれることで、受け部２６に対する規制部３４の位置ズレ（特に、挿入方向に交差する向きの位置ズレ）が抑制される。これにより、ブロック部３とフレーム部２との組み付けの際には、規制部３４が受け部２６に案内されることで組み付けの作業が容易になり、且つ、両者が組み付けられた後には、規制部３４と受け部２６との間の位置ズレが抑えられることで両者間の位置ズレ（ガタつき）を抑制できる。更に、組み付けの際、仮に規制部３４が受け部２６に適正に挿入されなかった場合、当て面２２に規制部３４の突出部３６が突き当たることで、挿入が不適正であることを作業者等が容易に認識できる。したがって、本実施形態に係る樹脂構造体１は、複数の樹脂体同士の組み付け性に優れる。 <Action / effect>
From the above, according to the resin structure 1 according to the present embodiment, when the frame portion 2 and the block portion 3 are assembled, the lock portion 33 of the block portion 3 and the locked portion 13 of the frame portion 2 are engaged with each other. , The regulating portion 34 of the block portion 3 is inserted into the receiving portion 26 of the frame portion 2 and accepted. Then, the plate-shaped portion 35 of the regulating portion 34 is sandwiched between the first groove portions 17 of the receiving portion 26, and the protruding portion 36 of the regulating portion 34 is sandwiched between the second groove portions 18 of the receiving portion 26. The positional deviation of the regulating portion 34 with respect to the insertion direction (particularly, the positional deviation in the direction intersecting the insertion direction) is suppressed. As a result, when assembling the block portion 3 and the frame portion 2, the regulating portion 34 is guided to the receiving portion 26, which facilitates the assembling work, and after both are assembled, the regulation portion 34 is regulated. By suppressing the positional deviation between the portion 34 and the receiving portion 26, it is possible to suppress the positional deviation (rattling) between the two portions. Further, at the time of assembly, if the regulating portion 34 is not properly inserted into the receiving portion 26, the protruding portion 36 of the regulating portion 34 abuts on the contact surface 22, and the operator or the like indicates that the insertion is improper. Can be easily recognized. Therefore, the resin structure 1 according to the present embodiment is excellent in assembling property between a plurality of resin bodies.

更に、本実施形態に係る樹脂構造体１によれば、当て面２２の縁部から延びる囲み壁２３により、当て面２２が囲まれた状態となる。よって、組み付けの際に規制部３４が受け部２６に適正に挿入されなかった場合、当て面２２に突き当たった突出部３６が、当て面２２に沿って滑るように移動したとしても、当て面２２の外にまで移動する（即ち、当て面２２から逃げる）ことが抑制される。これにより、挿入が不適正であることを作業者等が容易かつより確実に認識できる。 Further, according to the resin structure 1 according to the present embodiment, the contact surface 22 is surrounded by the surrounding wall 23 extending from the edge portion of the contact surface 22. Therefore, if the regulating portion 34 is not properly inserted into the receiving portion 26 during assembly, even if the protruding portion 36 that abuts on the contact surface 22 slides along the contact surface 22, the contact surface 22 Movement to the outside of the (that is, escaping from the contact surface 22) is suppressed. As a result, the operator or the like can easily and more reliably recognize that the insertion is improper.
