 上述のインサイドハンドルを含む一般的なハンドルでは、ハンドルを取り付けるための取付部は、軽量化等の為に、内空間を有することがあり得る。また、把持部は、軽量化等の為に、中空領域を有することがあり得る。このようなハンドルでは、内空間及び中空領域を設けたことによる強度の減少を補うために、取付部の内空間と中空領域との間に壁(以下、隔壁)を備えるように構成されることがある。 In a general handle including the above-mentioned inside handle, the mounting portion for mounting the handle may have an inner space for weight reduction and the like. Further, the grip portion may have a hollow region for weight reduction and the like. In such a handle, in order to compensate for the decrease in strength due to the provision of the inner space and the hollow region, a wall (hereinafter referred to as a partition wall) is provided between the inner space of the mounting portion and the hollow region. There is.
 しかしながら、光輝材を含む樹脂材料を用いる場合、上述のような隔壁が設けられている部位では外観において色むらが生じ易い為、色むらによってハンドルの意匠面ひいてはハンドルの美観が損なわれる、という課題が見出された。 However, when a resin material containing a bright material is used, color unevenness is likely to occur in the appearance of the portion where the partition wall is provided as described above, so that the color unevenness impairs the design surface of the handle and the aesthetic appearance of the handle. Was found.
 本開示の1つの局面は、光輝材を含む樹脂材料を用いて形成されたハンドルにおいて、美観が損なわれることを抑制する技術を提供することにある。 One aspect of the present disclosure is to provide a technique for suppressing spoiling of aesthetics in a handle formed by using a resin material containing a bright material.
 本開示の1つの局面は、光輝材を含む樹脂材料を用いて形成され、予め定められた意匠面と意匠面以外の非意匠面とを含むハンドルである。ハンドルは、取付部と、把持部と、ゲート痕と、を備える。取付部は、当該ハンドルを取付対象に取り付ける為のものである。把持部は、当該ハンドルの使用者に把持されるものである。ゲート痕は、非意匠面に設けられ、樹脂材料が注入された痕を示す。意匠面は、少なくとも把持部の主面に形成されている。把持部は、意匠面が形成された意匠部位と意匠部位に対向する非意匠部位とを有し、意匠部位と非意匠部位との間に中空領域が形成されている。中空領域は、把持部から取付部の内空間へと連通するように構成される。 One aspect of the present disclosure is a handle that is formed using a resin material containing a bright material and includes a predetermined design surface and a non-design surface other than the design surface. The handle comprises a mounting portion, a grip portion, and a gate mark. The mounting portion is for mounting the handle on the mounting target. The grip portion is to be gripped by the user of the handle. The gate mark is provided on the non-designed surface and indicates a mark into which the resin material is injected. The design surface is formed at least on the main surface of the grip portion. The grip portion has a design portion on which the design surface is formed and a non-design portion facing the design portion, and a hollow region is formed between the design portion and the non-design portion. The hollow region is configured to communicate from the grip portion to the inner space of the mounting portion.
 本開示のハンドルでは、中空領域は把持部から取付部の内空間へと連通している。つまり、内空間と中空領域との間にこれらの連通を塞ぐ隔壁を備えないので、内空間と中空領域との間(すなわち、内空間と中空領域とが接続する部位)において色むらが生じることが抑制される。結果として、光輝材を含む樹脂材料を用いて形成されたハンドルにおいて、色むらを抑制することができ、美観が損なわれることを抑制することができる。 In the handle of the present disclosure, the hollow region communicates from the grip portion to the inner space of the mounting portion. That is, since the partition wall that blocks these communication is not provided between the inner space and the hollow region, color unevenness occurs between the inner space and the hollow region (that is, the portion where the inner space and the hollow region are connected). Is suppressed. As a result, in the handle formed by using the resin material containing the brilliant material, color unevenness can be suppressed and the aesthetic appearance can be suppressed.

 ハンドル1は、取付部2と、ゲート痕6と、把持部3と、を備える。意匠面41は、少なくとも把持部3の主面(具体的には、把持部3の主面のうちの使用者から見えやすい面)に形成される。主面とは、露呈される面のうちの主たる面をいう。本実施形態では、意匠面41は、把持部3の主面であって使用者から見えやすい面から取付部2にわたって形成されている。把持部3の主面のうちの使用者から見えやすい面とは、ハンドル1がドアに取り付けられたときの車室の内外方向(すなわち、Y軸)に垂直な面であって最も車室内側の面、をいう。 The handle 1 includes a mounting portion 2, a gate mark 6, and a grip portion 3. The design surface 41 is formed at least on the main surface of the grip portion 3 (specifically, the surface of the main surface of the grip portion 3 that is easily visible to the user). The main surface is the main surface of the exposed surfaces. In the present embodiment, the design surface 41 is formed from a surface that is the main surface of the grip portion 3 and is easily visible to the user to the mounting portion 2. The surface of the main surface of the grip portion 3 that is easily visible to the user is the surface that is perpendicular to the inside / outside direction (that is, the Y axis) of the vehicle interior when the handle 1 is attached to the door, and is the most interior side.

Further, the design surface 41 and the non-design surface 51 may be inclined.
 <取付部>
 取付部2は、ハンドル1を取付対象であるドアに取り付ける為の部位である。取付部2は、内部に空間(以下、内空間23)を有する。具体的には、取付部2は、意匠面41の長手方向(すなわち、車両の前後方向)における端部のうち使用者によって把持される端部から遠い側(すなわち、車両の後方側)の端部において、該意匠面41の外縁から立設した2つの側壁を備える。2つの側壁は、互いに略平行に、ハンドル1が取り付けられたときの車室外方向に立設している。2つの側壁のうち、ハンドル1が取り付けられたときの上側に位置する側壁を上取付壁部21とし、下側に位置する側壁を下取付壁部22とする。取付部2は、図2に示すように、上取付壁部21と下取付壁部22との間に内空間23を有する。
<Mounting part>
The mounting portion 2 is a portion for mounting the handle 1 to the door to be mounted. The mounting portion 2 has a space (hereinafter referred to as an inner space 23) inside. Specifically, the mounting portion 2 is the end of the design surface 41 in the longitudinal direction (that is, the front-rear direction of the vehicle) that is far from the end gripped by the user (that is, the rear side of the vehicle). The portion is provided with two side walls erected from the outer edge of the design surface 41. The two side walls are erected substantially parallel to each other in the direction outside the vehicle interior when the steering wheel 1 is attached. Of the two side walls, the side wall located on the upper side when the handle 1 is attached is referred to as the upper mounting wall portion 21, and the side wall located on the lower side is referred to as the lower mounting wall portion 22. As shown in FIG. 2, the mounting portion 2 has an inner space 23 between the upper mounting wall portion 21 and the lower mounting wall portion 22.
 また、取付部2は、軸穴25と、ロック穴26と、を備える。具体的には、軸穴25が上取付壁部21及び下取付壁部22に形成され、ロック穴26が下取付壁部22に形成される。上取付壁部21及び下取付壁部22に形成された軸穴25には、ハンドル1をドアに回動可能に取り付けるための取付軸が挿入される。取付軸は、ドアの室外側(すなわち、車室内であってドアにおける室外側)に取り付けられる。つまり、取付部2ひいてはハンドル1は、ドアの取付軸を中心として回動可能にドアの室外側に取り付けられる。ロック穴26は、軸又はワイヤー等によってドアのロック機構と連結される。 Further, the mounting portion 2 includes a shaft hole 25 and a lock hole 26. Specifically, the shaft hole 25 is formed in the upper mounting wall portion 21 and the lower mounting wall portion 22, and the lock hole 26 is formed in the lower mounting wall portion 22. A mounting shaft for rotatably mounting the handle 1 to the door is inserted into the shaft hole 25 formed in the upper mounting wall portion 21 and the lower mounting wall portion 22. The mounting shaft is mounted outside the door (ie, inside the vehicle and outside the door). That is, the mounting portion 2 and thus the handle 1 are rotatably mounted on the outdoor side of the door about the mounting shaft of the door. The lock hole 26 is connected to the door locking mechanism by a shaft, a wire, or the like.
 <ゲート痕>
 ゲート痕6は、取付部2における非意匠面に形成されている。ゲート痕6は、ハンドル1の射出成形の際に、射出成形用型の内部に形成される空間(以下、キャビティ)内に溶融樹脂を注入するための注入ゲート内で固化したゲート部分を除去した後に残る切断痕である。つまり、ゲート痕6は、樹脂材料が注入された痕であり、取付部2の表面に形成されるともいえる。
<Gate mark>
The gate mark 6 is formed on the non-design surface of the mounting portion 2. In the gate mark 6, the gate portion solidified in the injection gate for injecting the molten resin into the space (hereinafter, cavity) formed inside the injection molding mold during the injection molding of the handle 1 was removed. It is a cutting mark left behind. That is, it can be said that the gate mark 6 is a mark into which the resin material is injected and is formed on the surface of the mounting portion 2.
 本実施形態では、サイドゲート式の射出成形機が用いられる。ハンドル1では、射出成形の際に、注入ゲートを通じてキャビティ内に射出された溶融樹脂が、キャビティ内を、取付部2を形成するためのキャビティ側から把持部3を形成するためのキャビティ側へ向かって流動し、キャビティ内に充填されて固化する。これによりハンドル1が形成される。 In this embodiment, a side gate type injection molding machine is used. In the handle 1, the molten resin injected into the cavity through the injection gate during injection molding moves in the cavity from the cavity side for forming the mounting portion 2 to the cavity side for forming the grip portion 3. Flows, fills the cavity and solidifies. As a result, the handle 1 is formed.
 研究の結果、光輝材を含む樹脂材料を用いる樹脂成形品であるハンドル1において、ゲート痕6の近辺(すなわち、樹脂成形時の注入ゲートと樹脂成形用型のキャビティとの連結部分の近辺)に、シルバーストリークが生じ得ることが明らかになった。換言すれば、ゲート痕6から離れた位置において、シルバーストリークが生じ難いことが明らかになった。 As a result of research, in the handle 1 which is a resin molded product using a resin material containing a bright material, in the vicinity of the gate mark 6 (that is, in the vicinity of the connecting portion between the injection gate at the time of resin molding and the cavity of the resin molding mold). , It became clear that silver streak could occur. In other words, it became clear that silver streak is unlikely to occur at a position away from the gate mark 6.
 本実施形態では、ハンドル1において、取付部2は、意匠面41から予め定められた距離であるゲート距離D以上離れた位置にゲート痕6を有するように形成されている。ここでいうゲート距離Dとは、ゲート痕6の上辺61から、ゲート痕6に最も近い意匠面41の端辺(すなわち、意匠面41の端部を表す辺)411迄、樹脂成形の際に溶融樹脂が流れる距離をいう。また、意匠面41から離れるとは、意匠面41から、ハンドル1がドアに取り付けられたときの室外側へ離れることをいう。 In the present embodiment, in the handle 1, the mounting portion 2 is formed so as to have a gate mark 6 at a position separated from the design surface 41 by a gate distance D or more, which is a predetermined distance. The gate distance D referred to here is from the upper side 61 of the gate mark 6 to the end side of the design surface 41 closest to the gate mark 6 (that is, the side representing the end portion of the design surface 41) 411 during resin molding. The distance through which the molten resin flows. Further, "away from the design surface 41" means that the handle 1 is separated from the design surface 41 to the outdoor side when the handle 1 is attached to the door.
 なお、意匠面41の端辺411が傾斜している場合あるいは曲線である場合は、図2のように記述される2次元平面(つまり、Y-Z平面)において、意匠面41の端辺411を構成する点群のうちいずれかの点を含んでゲート痕6の上辺に平行な線412を特定する。そして、ゲート痕6の上辺61から、上述のゲート痕6の上辺に平行な線412迄、樹脂成形の際に溶融樹脂が流れる距離が最小となる距離を、ゲート距離Dとして規定することができる。 If the end side 411 of the design surface 41 is inclined or curved, the end side 411 of the design surface 41 is in a two-dimensional plane (that is, a YY plane) described as shown in FIG. A line 412 including any of the points constituting the gate mark 6 and parallel to the upper side of the gate mark 6 is specified. Then, the distance from the upper side 61 of the gate mark 6 to the line 412 parallel to the upper side of the gate mark 6 to minimize the distance through which the molten resin flows during resin molding can be defined as the gate distance D. ..
 また、研究の結果、シルバーストリークを生じ難くするためには、ゲート距離Dが5mm以上であることが明らかになった。本実施形態においても、ハンドル1は、ゲート距離Dが5mm以上となるように、形成されている。つまり、射出成形用型は、ゲート距離Dが上述の距離となるように形成されている。 In addition, as a result of research, it became clear that the gate distance D is 5 mm or more in order to make it difficult for silver streaks to occur. Also in this embodiment, the handle 1 is formed so that the gate distance D is 5 mm or more. That is, the injection molding mold is formed so that the gate distance D is the above-mentioned distance.
 また、光輝材を含む樹脂材料を用いる樹脂成形品であるハンドル1において、ゲート痕6の断面積が所定の面積以上であり、且つ、ゲート痕6の高さ(以下、ゲート高さH)が所定の高さ以上である場合に、シルバーストリークが生じ難いことが明らかになった。ここでいうゲート高さHとは、ハンドル1がドアに取り付けられたときの車室の内外方向における高さをいう。 Further, in the handle 1, which is a resin molded product using a resin material containing a bright material, the cross-sectional area of the gate mark 6 is equal to or larger than a predetermined area, and the height of the gate mark 6 (hereinafter, gate height H) is large. It became clear that silver streak is unlikely to occur when the height is above the specified height. The gate height H here means the height in the inside / outside direction of the vehicle interior when the steering wheel 1 is attached to the door.
 すなわち、図2のように記述される2次元平面(つまり、Y-Z平面)において、ゲート痕6における下辺62と上辺61との距離を、ゲート高さHとして規定することができる。 That is, in the two-dimensional plane (that is, the YY plane) described as shown in FIG. 2, the distance between the lower side 62 and the upper side 61 in the gate mark 6 can be defined as the gate height H.
 また、研究の結果、ハンドル1は、ゲート痕6が、断面積が10mm2以上であって、且つ、ゲート高さHが2mmを上回る、という条件を満たすように形成されることが好適であること、が明らかになった。本実施形態においても、ハンドル1は、ゲート痕6の断面積及びゲート高さHが上述の条件を満たすように形成されている。つまり、射出成形用型は、樹脂成形時の注入ゲートとキャビティとの連結部分の断面積及びゲート高さHが上述の条件を満たすように形成されている。 Further, as a result of research, it is preferable that the handle 1 is formed so that the gate mark 6 satisfies the condition that the cross-sectional area is 10 mm 2 or more and the gate height H exceeds 2 mm. That became clear. Also in this embodiment, the handle 1 is formed so that the cross-sectional area of the gate mark 6 and the gate height H satisfy the above conditions. That is, the injection molding mold is formed so that the cross-sectional area of the connecting portion between the injection gate and the cavity at the time of resin molding and the gate height H satisfy the above conditions.
 <把持部>
 把持部3は、車両のドアの開閉のために、ハンドル1の使用者(すなわち、本実施形態では車両の乗員)によって把持される部位である。把持部3は、図3に示すように、意匠部位4と非意匠部位5とを備える。意匠部位4は、ハンドル1がドアに取り付けられたときの車室の内外方向を法線方向とする平板状に形成された部位であって室内に最も近い側に設けられた部位である。意匠部位4は、把持部3において、意匠面41が形成されている部位である。非意匠部位5は、意匠部位4と対向するように設けられている。
<Grip part>
The grip portion 3 is a portion gripped by the user of the steering wheel 1 (that is, the occupant of the vehicle in the present embodiment) for opening and closing the door of the vehicle. As shown in FIG. 3, the grip portion 3 includes a design portion 4 and a non-design portion 5. The design portion 4 is a portion formed in a flat plate shape having the inside / outside direction of the vehicle interior as the normal direction when the steering wheel 1 is attached to the door, and is a portion provided on the side closest to the interior. The design portion 4 is a portion of the grip portion 3 on which the design surface 41 is formed. The non-designed portion 5 is provided so as to face the designed portion 4.
 非意匠部位5は、ハンドル1がドアに取り付けられたときの車室の内外方向を法線方向とする平板状に形成された部位であって室外に最も近い側に設けられた部位である。非意匠部位5は非意匠面51を備える。 The non-designed portion 5 is a portion formed in a flat plate shape with the inside / outside direction of the passenger compartment as the normal direction when the steering wheel 1 is attached to the door, and is a portion provided on the side closest to the outside. The non-designed portion 5 includes a non-designed surface 51.
 つまり、把持部3における主面であって、ハンドル1がドアに取り付けられたときの車室の内外方向に略垂直な2つの主面のうち、一方(すなわち、最も室内に近い側)は意匠面41であり、他方(すなわち、最も室外に近い側)は非意匠面51である。 That is, one of the two main surfaces of the grip portion 3 that is substantially perpendicular to the inside and outside of the vehicle interior when the handle 1 is attached to the door (that is, the side closest to the interior) is the design. The surface 41, the other (that is, the side closest to the outdoor) is the non-designed surface 51.
 意匠部位4と非意匠部位5との間には中空領域31が形成されている。中空領域31とは、中空の空間である。具体的には、把持部3には、図3に示すように、少なくとも一部において意匠面41と非意匠面51とが連結した状態で、中空領域31が形成されている。 A hollow region 31 is formed between the design portion 4 and the non-design portion 5. The hollow region 31 is a hollow space. Specifically, as shown in FIG. 3, the grip portion 3 is formed with a hollow region 31 in a state where the design surface 41 and the non-design surface 51 are connected to each other at least in part.
 本実施形態では、把持部3における取付部2とは反対側の端部を連結部32として、連結部32にて意匠面41と非意匠面51とが連結しており、中空領域31が形成されている。把持部3における取付部2とは反対側の端部とは、ハンドル1がドアに取り付けられたときの車室前方側の端部である。 In the present embodiment, the end portion of the grip portion 3 opposite to the mounting portion 2 is used as the connecting portion 32, and the design surface 41 and the non-design surface 51 are connected by the connecting portion 32 to form the hollow region 31. Has been done. The end portion of the grip portion 3 opposite to the mounting portion 2 is the end portion on the front side of the vehicle interior when the handle 1 is attached to the door.
 また、本実施形態では、上取付壁部21から連結部32に延設された上面部38を介しても意匠面41と非意匠面51とが連結しており、中空領域31が形成されている。把持部3は、前後方向(すなわち、X軸)に垂直な面における断面がU字状に形成されており、U字において凹んでいる領域が中空領域31に相当する。図3、図4に示すように、中空領域31は、把持部3から、すなわち連結部32から、取付部2の内空間23へと延びるように形成されている。 Further, in the present embodiment, the design surface 41 and the non-design surface 51 are connected to each other via the upper surface portion 38 extending from the upper mounting wall portion 21 to the connecting portion 32, and the hollow region 31 is formed. There is. The grip portion 3 has a U-shaped cross section on a surface perpendicular to the front-rear direction (that is, the X-axis), and the recessed region in the U-shape corresponds to the hollow region 31. As shown in FIGS. 3 and 4, the hollow region 31 is formed so as to extend from the grip portion 3, that is, from the connecting portion 32 to the inner space 23 of the mounting portion 2.
 このように、本実施形態では、把持部3は、連結部32及び上面部38の両方において、意匠面41と非意匠面51とが連結しており、中空領域31が形成されている。これにより、樹脂成形の際、注入ゲートを通じてキャビティ内に射出された溶融樹脂は、樹脂成形用型のキャビティ内を、意匠面41を形成するためのキャビティ側から非意匠面51を形成するためのキャビティ側へ向かって流動する。 As described above, in the present embodiment, in the grip portion 3, the design surface 41 and the non-design surface 51 are connected to each other in both the connecting portion 32 and the upper surface portion 38, and the hollow region 31 is formed. As a result, the molten resin injected into the cavity through the injection gate during resin molding forms the non-design surface 51 from the cavity side for forming the design surface 41 in the cavity of the resin molding mold. It flows toward the cavity side.
 つまり、溶融樹脂が意匠面41を形成するためのキャビティへ先に流動していくため、意匠面41における溶融樹脂の流動の乱れが抑制され、意匠面41におけるウェルドラインが抑制される。また、本実施形態では、意匠面41を備える意匠部位4は、略均一な肉厚に形成されている。これにより、意匠面41におけるヒケ等の成形不良が抑制される。なお、意匠部位4の肉厚は、非意匠面51を備える非意匠部位5の肉厚よりも厚く形成されている。ここでいう肉厚とは、ハンドル1がドアに取り付けられたときの車室の内外方向における厚み(すなわち、距離)をいう。 That is, since the molten resin flows first to the cavity for forming the design surface 41, the turbulence of the flow of the molten resin on the design surface 41 is suppressed, and the weld line on the design surface 41 is suppressed. Further, in the present embodiment, the design portion 4 provided with the design surface 41 is formed to have a substantially uniform wall thickness. As a result, molding defects such as sink marks on the design surface 41 are suppressed. The wall thickness of the design portion 4 is formed to be thicker than the wall thickness of the non-design portion 5 including the non-design surface 51. The wall thickness here means the thickness (that is, the distance) in the inside / outside direction of the passenger compartment when the steering wheel 1 is attached to the door.
 ハンドル1は、取付対象に取り付けられた際に、意匠面41が使用者に露呈するようになっている。つまり、ハンドル1は、上述のように取付部2の軸穴25に軸部材が挿通されドアの室内側の面に取り付けられた際に、意匠面41が室内側に露呈するようになっている。意匠面41は、使用者に視認されやすい位置に設けられるため、優れた(すなわち、美麗な)外観を必要とする。 When the handle 1 is attached to the attachment target, the design surface 41 is exposed to the user. That is, when the shaft member is inserted into the shaft hole 25 of the mounting portion 2 and mounted on the indoor surface of the door as described above, the design surface 41 of the handle 1 is exposed to the indoor side. .. Since the design surface 41 is provided at a position easily visible to the user, an excellent (that is, beautiful) appearance is required.
 光輝材を含む樹脂材料を用いた樹脂成形品では、所謂色むらが生じて外観不良となり得る為、意匠面41においては、外観不良の要因となる色むらを抑制する必要がある。 In a resin molded product using a resin material containing a bright material, so-called color unevenness may occur and the appearance may be poor. Therefore, on the design surface 41, it is necessary to suppress the color unevenness that causes the appearance deterioration.
 色むらとは、色が変化して見えることをいう。例えば、光輝材の濃度等の違いによる光の反射具合の変化により色が変化して見え得る。また例えば、光輝材を含む溶融樹脂の密度の具合により色が変化して見え得る。ここでいう色むらには、シルバーストリーク、ウェルドライン等も含む。 Color unevenness means that the color looks different. For example, the color may change due to a change in the degree of light reflection due to a difference in the density of the bright material or the like. Further, for example, the color may change depending on the density of the molten resin containing the bright material. The color unevenness here includes silver streaks, weld lines, and the like.
 色むらは、樹脂成形の際に、射出成形用型のキャビティに注入される溶融樹脂が、キャビティの形状に応じて流動した結果として生じる。溶融樹脂に光輝材が含まれる場合は、溶融樹脂に光輝材が含まれない場合よりも、色むらがより顕著に生じ得る。また、キャビティが突起形状部を形成するように形作られている場合、光輝材が含まれる溶融樹脂がその突起形状部付近において滞留し、その突起形状部付近では外観において色むらが生じ得る。突起形状部には、分岐や突起や壁等が含まれる。 Color unevenness occurs as a result of the molten resin injected into the cavity of the injection molding mold flowing according to the shape of the cavity during resin molding. When the molten resin contains a bright material, color unevenness may occur more prominently than when the molten resin does not contain a bright material. Further, when the cavity is formed so as to form a protrusion-shaped portion, the molten resin containing the bright material may stay in the vicinity of the protrusion-shaped portion, and color unevenness may occur in the appearance in the vicinity of the protrusion-shaped portion. The protrusion-shaped portion includes branches, protrusions, walls, and the like.
 そこで、本実施形態では、図4、図5、図6に示すように、ハンドル1は、把持部3から取付部2の内空間23側へ延びるように形成されている上述の中空領域31が、把持部3から取付部2の内空間23へと連通するように形成されている。 Therefore, in the present embodiment, as shown in FIGS. 4, 5, and 6, the handle 1 has the above-mentioned hollow region 31 formed so as to extend from the grip portion 3 toward the inner space 23 side of the mounting portion 2. , Is formed so as to communicate from the grip portion 3 to the inner space 23 of the mounting portion 2.
 ここで比較の為、中空領域31が把持部3から取付部2の内空間23へと連通していない比較例としてのハンドル9における、本開示の図5に対応する図を図7に示し、本開示の図6に対応する図を図8に示す。つまり、比較例のハンドル9は中空領域31と内空間23とを完全に遮る隔壁99を備えている。 Here, for comparison, FIG. 7 shows a diagram corresponding to FIG. 5 of the present disclosure in the handle 9 as a comparative example in which the hollow region 31 does not communicate from the grip portion 3 to the inner space 23 of the mounting portion 2. The figure corresponding to FIG. 6 of the present disclosure is shown in FIG. That is, the handle 9 of the comparative example includes a partition wall 99 that completely blocks the hollow region 31 and the inner space 23.
 本開示のハンドル1は、このような比較例のハンドル9とは異なり、中空領域31と内空間23とを完全に遮る隔壁99を備えない。つまり、樹脂成形の際に射出成形用型のキャビティにおいて、内空間23と中空領域31とが接続する部位に形成される突起形状部が欠落している。これにより、意匠部位4における中空領域31側の面では、内空間23と中空領域31とが接続する部位において、溶融樹脂に含まれる光輝材の滞留が抑制される。光輝材が滞留することが抑制されるので、意匠面41に色むらが生じることが抑制される。 Unlike the handle 9 of the comparative example, the handle 1 of the present disclosure does not have a partition wall 99 that completely blocks the hollow region 31 and the inner space 23. That is, in the cavity of the injection molding mold during resin molding, the protrusion-shaped portion formed at the portion where the inner space 23 and the hollow region 31 are connected is missing. As a result, on the surface of the design portion 4 on the hollow region 31 side, the retention of the bright material contained in the molten resin is suppressed at the portion where the inner space 23 and the hollow region 31 are connected. Since the retention of the bright material is suppressed, the color unevenness on the design surface 41 is suppressed.
 更に、連通穴33は、図5、図6に示すように、意匠部位4における中空領域31側の面42が平滑となるように形成されている。連通穴33とは、中空領域31において把持部3から取付部2の内空間23へ連通する空間をいう。把持部3において意匠面41を主面とする部位を意匠部位4という。つまり、樹脂成形用型のキャビティにおいて意匠部位4における中空領域31側の面を形成する部位は、平滑となるように形成されている。 Further, as shown in FIGS. 5 and 6, the communication hole 33 is formed so that the surface 42 on the hollow region 31 side in the design portion 4 is smooth. The communication hole 33 means a space that communicates from the grip portion 3 to the inner space 23 of the mounting portion 2 in the hollow region 31. The portion of the grip portion 3 whose main surface is the design surface 41 is referred to as a design portion 4. That is, in the cavity of the resin molding mold, the portion of the design portion 4 that forms the surface on the hollow region 31 side is formed so as to be smooth.
 平滑に形成されるとは、意匠部位4における中空領域31側の面42を形成する部位に、突起形状部が形成されておらず、且つ、表面が滑らかであることをいう。表面が滑らかとは、表面に凹凸が無いことをいう。なお、表面に凹凸が無いとは、厳密な意味での表面に凹凸が無いことに限るものではなく、同様の効果を奏するのであれば厳密に表面に凹凸が無いものでなくてもよい。 The term "smoothly formed" means that the protrusion-shaped portion is not formed and the surface is smooth at the portion of the design portion 4 where the surface 42 on the hollow region 31 side is formed. Smooth surface means that there is no unevenness on the surface. It should be noted that the fact that there is no unevenness on the surface is not limited to the fact that there is no unevenness on the surface in a strict sense, and it does not have to be exactly on the surface as long as the same effect is obtained.
 これにより、意匠部位4における中空領域31側の面では、内空間23と中空領域31とが接続する部位において、溶融樹脂に含まれる光輝材の滞留がさらに抑制される。光輝材が滞留することが抑制されるので、意匠面41に色むらが生じることがさらに抑制される。 As a result, on the surface of the design portion 4 on the hollow region 31 side, the retention of the bright material contained in the molten resin is further suppressed at the portion where the inner space 23 and the hollow region 31 are connected. Since the retention of the bright material is suppressed, the occurrence of color unevenness on the design surface 41 is further suppressed.
 また、本実施形態では、意匠面41に、シボ加工と呼ばれる、凹凸加工が施されている。凹凸加工の深さの範囲は、2μm以上3μm以下である。つまり、樹脂成形用型のキャビティにおいて意匠面41を形成する部位には、微細な凹凸模様が刻まれている。樹脂成形用型において、このような微細な凹凸模様を刻む方法(すなわち、シボ加工の方法)としては、エッチングによるシボ加工やブラストによるシボ加工等といった方法が採用され得る。 Further, in the present embodiment, the design surface 41 is subjected to uneven processing called grain processing. The range of the depth of uneven processing is 2 μm or more and 3 μm or less. That is, in the cavity of the resin molding mold, a fine uneven pattern is engraved on the portion forming the design surface 41. In the resin molding mold, as a method of carving such a fine uneven pattern (that is, a method of embossing), a method such as embossing by etching or embossing by blasting can be adopted.
 また、本実施形態では、図5、図6に示すように、ハンドル1は、連通穴33の非意匠面51側(すなわち、意匠面41とは反対側)の端部331が、非意匠部位5における中空領域31側の面から起立する補強壁52の端部53によって規定されている。把持部3において非意匠面51を主面とする部位を非意匠部位5という。 Further, in the present embodiment, as shown in FIGS. 5 and 6, in the handle 1, the end portion 331 of the communication hole 33 on the non-design surface 51 side (that is, the side opposite to the design surface 41) is a non-design portion. It is defined by the end portion 53 of the reinforcing wall 52 rising from the surface on the hollow region 31 side in 5. The portion of the grip portion 3 whose main surface is the non-designed surface 51 is referred to as a non-designed portion 5.
 連通穴33の非意匠面51側の端部331とは、ハンドル1がドアに取り付けられたときの室外側の端部であって、図5、図6の紙面における下端部をいう。補強壁52の端部53とは、ハンドル1がドアに取り付けられたときの室内側の端部であって、図5、図6の紙面における上端部をいう。つまり、図5、図6に示すように、連通穴33の非意匠面51側の端部331は、補強壁52の端部53であると言い換えることができる。 The end portion 331 on the non-design surface 51 side of the communication hole 33 is the end portion on the outdoor side when the handle 1 is attached to the door, and refers to the lower end portion on the paper surface of FIGS. 5 and 6. The end portion 53 of the reinforcing wall 52 is the end portion on the indoor side when the handle 1 is attached to the door, and refers to the upper end portion on the paper surface of FIGS. 5 and 6. That is, as shown in FIGS. 5 and 6, the end portion 331 of the communication hole 33 on the non-designed surface 51 side can be rephrased as the end portion 53 of the reinforcing wall 52.
 ハンドル1は、連通穴33において、意匠面41が位置する方向とは反対の方向に補強壁52を備えるので、上述のように射出成形時における意匠面41の美観が維持されるとともに、連通穴33の周囲における強度が補われる。 Since the handle 1 includes the reinforcing wall 52 in the communication hole 33 in the direction opposite to the direction in which the design surface 41 is located, the aesthetic appearance of the design surface 41 at the time of injection molding is maintained as described above, and the communication hole is maintained. The strength around 33 is supplemented.
 [2.効果]
 以上詳述した実施形態によれば、以下の効果を奏する。
[2. effect]
According to the embodiment described in detail above, the following effects are obtained.
 (2a)意匠面41は、少なくとも把持部3の主面に形成されている。把持部3は、意匠面41が形成された意匠部位4と、意匠部位4に対向する非意匠部位5とを有する。意匠部位4と非意匠部位5との間に中空領域31が形成されており、中空領域31は把持部3から取付部2の内空間23へと連通している。 (2a) The design surface 41 is formed on at least the main surface of the grip portion 3. The grip portion 3 has a design portion 4 on which the design surface 41 is formed, and a non-design portion 5 facing the design portion 4. A hollow region 31 is formed between the design portion 4 and the non-design portion 5, and the hollow region 31 communicates from the grip portion 3 to the inner space 23 of the mounting portion 2.
 つまり、ハンドル1では、樹脂成形の際に、射出成形用型のキャビティ内において、内空間23と中空領域31とが接続する部位に形成される突起形状部が欠落している。これにより、樹脂成形の際、意匠部位4を形成するキャビティ内において、意匠部位4における中空領域31側の面では、内空間23と中空領域31とが接続する部位において、溶融樹脂に含まれる光輝材の滞留が抑制される。この結果、意匠面41に色むらが生じることが抑制される。 That is, in the handle 1, the protrusion-shaped portion formed at the portion where the inner space 23 and the hollow region 31 are connected is missing in the cavity of the injection molding mold during resin molding. As a result, in the cavity forming the design portion 4 during resin molding, on the surface of the design portion 4 on the hollow region 31 side, the brilliance contained in the molten resin at the portion where the inner space 23 and the hollow region 31 are connected. The retention of the material is suppressed. As a result, it is possible to prevent color unevenness from occurring on the design surface 41.
 結果として、光輝材を含む樹脂材料を用いて形成されたハンドル1において、美観が損なわれることを抑制することができる。なお、ハンドル1では、樹脂成形の際に、射出成形用型のキャビティ内において、内空間23と中空領域31とが接続する部位に形成される突起形状部が欠落しているので、色むらに加えて、ひけを抑制することもできる。 As a result, it is possible to suppress the deterioration of the aesthetic appearance of the handle 1 formed by using the resin material including the bright material. It should be noted that the handle 1 lacks a protrusion-shaped portion formed at a portion where the inner space 23 and the hollow region 31 are connected in the cavity of the injection molding mold during resin molding. In addition, sink marks can be suppressed.
 (2b)ゲート痕6は、取付部2における非意匠面に形成されている。また、ゲート痕6は、意匠面41からゲート距離D以上離れた位置に設けられている。これにより、ゲート距離Dを適宜定めることにより、意匠面41におけるシルバーストリークを抑制することができる。 (2b) The gate mark 6 is formed on the non-design surface of the mounting portion 2. Further, the gate mark 6 is provided at a position separated from the design surface 41 by a gate distance D or more. Thereby, by appropriately determining the gate distance D, silver streak on the design surface 41 can be suppressed.
 (2c)ハンドル1は、ゲート距離Dが5mm以上であるように構成されている。これにより、意匠面41におけるシルバーストリークを抑制することができる。 (2c) The handle 1 is configured so that the gate distance D is 5 mm or more. As a result, silver streak on the design surface 41 can be suppressed.
 (2d)ハンドル1は、ゲート痕6が、断面積が10mm2以上であって、且つ、ゲート高さHが2mmを上回るように構成されている。これにより、樹脂成形の際、光輝材を含む溶融樹脂が流動しやすくなる。つまり、光輝材が滞留することが抑制されるので、結果として、色むらを抑制することができる。 (2d) The handle 1 is configured such that the gate mark 6 has a cross-sectional area of 10 mm 2 or more and a gate height H of more than 2 mm. This makes it easier for the molten resin containing the bright material to flow during resin molding. That is, the retention of the bright material is suppressed, and as a result, color unevenness can be suppressed.
 (2e)把持部3では、少なくとも一部において、意匠部位4が備える意匠面41と、非意匠部位5が備える非意匠面51とが連結した状態で、中空領域31が形成されている。このため、樹脂成形の際、ゲート痕6が形成される位置から注入ゲートを通じてキャビティ内に射出された溶融樹脂が、非意匠面51よりも先に意匠面41を形成するためのキャビティへ流動していく。これにより、意匠面41における溶融樹脂の流動の乱れが抑制され、意匠面41におけるウェルドラインが抑制される。 (2e) In the grip portion 3, the hollow region 31 is formed in a state where the design surface 41 included in the design portion 4 and the non-design surface 51 included in the non-design portion 5 are connected to each other at least in a part. Therefore, during resin molding, the molten resin injected into the cavity through the injection gate from the position where the gate mark 6 is formed flows into the cavity for forming the design surface 41 before the non-design surface 51. To go. As a result, the turbulence of the flow of the molten resin on the design surface 41 is suppressed, and the weld line on the design surface 41 is suppressed.
 (2f)連通穴33は、意匠部位4における中空領域31側の面42が平滑となるように形成されている。これにより、意匠部位4における中空領域31側の面では、内空間23と中空領域31とが接続する部位において、突起形状部が無いので、色むらが生じることをより抑制することができる。 (2f) The communication hole 33 is formed so that the surface 42 on the hollow region 31 side in the design portion 4 is smooth. As a result, on the surface of the design portion 4 on the hollow region 31 side, since there is no protrusion-shaped portion in the portion where the inner space 23 and the hollow region 31 are connected, it is possible to further suppress the occurrence of color unevenness.
 (2g)連通穴33の非意匠面51側の端部331は、非意匠部位5における中空領域31側の面から起立する補強壁52の端部53によって規定されている。ハンドル1は、連通穴33において、意匠面41が位置する方向とは反対の方向に補強壁52を備えるので、意匠面41の美観を維持するとともに、連通穴33の周囲における強度を維持することができる。 (2g) The end portion 331 on the non-designed surface 51 side of the communication hole 33 is defined by the end portion 53 of the reinforcing wall 52 rising from the surface on the hollow region 31 side in the non-designed portion 5. Since the handle 1 includes the reinforcing wall 52 in the communication hole 33 in the direction opposite to the direction in which the design surface 41 is located, the aesthetic appearance of the design surface 41 and the strength around the communication hole 33 are maintained. Can be done.
 なお、中空領域31がない(つまり、肉抜きがない)と仮定した構成において、ハンドル1にて露呈される、対向して延びる二つの主面のうち、一方を意匠面41、他方を非意匠面51と定義することができる。この場合、意匠部位4における中空領域31側の面や、非意匠部位5における中空領域31側の面や、上面部38ならびに連結部32の各面は、意匠面41及び非意匠面51のいずれからも定義上外れるということができる。 In the configuration assuming that there is no hollow region 31 (that is, there is no lightening), one of the two facing main surfaces exposed by the handle 1 is the design surface 41 and the other is the non-design surface. It can be defined as a surface 51. In this case, the surface on the hollow region 31 side in the design portion 4, the surface on the hollow region 31 side in the non-design portion 5, and each surface of the upper surface portion 38 and the connecting portion 32 are either the design surface 41 or the non-design surface 51. It can be said that it is out of the definition.
 (2h)意匠面41には、2μm以上3μm以下の深さの凹凸加工が施されている。上述のように、本実施形態のハンドル1の意匠面41は色むらが生じることが抑制されているので、このような意匠面41に微細な凹凸加工を施すことによって、微細な凹凸加工が映え美しい外観を得ることができる。 (2h) The design surface 41 is subjected to uneven processing with a depth of 2 μm or more and 3 μm or less. As described above, the design surface 41 of the handle 1 of the present embodiment is suppressed from having color unevenness. Therefore, by applying fine uneven processing to such a design surface 41, the fine uneven processing can be seen. You can get a beautiful appearance.
 なお、上述の実施形態において、ハンドル(インサイドハンドル)1がハンドルに相当し、車両のドアが取付け対象に相当する。 In the above embodiment, the steering wheel (inside handle) 1 corresponds to the steering wheel, and the door of the vehicle corresponds to the mounting target.
 [3.他の実施形態]
 以上、本開示の実施形態について説明したが、本開示は上述の実施形態に限定されることなく、種々変形して実施することができる。
[3. Other embodiments]
Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and can be variously modified and implemented.
 (3a)上述の実施形態では、連通穴33は図5に示すように矩形状に形成されているが、連通穴33の形状はこれに限定されるものではなく、任意の形状であり得る。なお、ハンドル1において、連通穴33を形成するための部位(すなわち、連通穴33の周囲の部位)は、意匠面41に対して均一な厚みとなっていることがより望ましい。また、連通穴33は、意匠面41に沿う方向に、なるべく大きく開口していることが望ましい。意匠面41に沿う方向とは、ハンドル1の厚み方向、すなわち、ハンドル1が取り付けられたときの上下方向をいう。 (3a) In the above-described embodiment, the communication hole 33 is formed in a rectangular shape as shown in FIG. 5, but the shape of the communication hole 33 is not limited to this, and may be any shape. In the handle 1, it is more desirable that the portion for forming the communication hole 33 (that is, the portion around the communication hole 33) has a uniform thickness with respect to the design surface 41. Further, it is desirable that the communication hole 33 is opened as large as possible in the direction along the design surface 41. The direction along the design surface 41 is the thickness direction of the handle 1, that is, the vertical direction when the handle 1 is attached.
 (3b)ハンドル1は補強壁52を備えていなくてもよい。 (3b) The handle 1 does not have to be provided with the reinforcing wall 52.
 (3c)連結部32の位置は、把持部3における取付部2とは反対側の端部等に限定されるものではなく、把持部3における取付部2とは反対側の端部から内空間23に至るまでの間の任意の位置であってよい。つまり、把持部3における取付部2とは反対側の端部から連結部32までは意匠面41と非意匠面51とが連結しており、連結部32から内空間23に至るまでの間が中空領域31として形成されていてもよい。 (3c) The position of the connecting portion 32 is not limited to the end portion of the grip portion 3 opposite to the mounting portion 2, and is an inner space from the end portion of the grip portion 3 opposite to the mounting portion 2. It may be any position up to 23. That is, the design surface 41 and the non-design surface 51 are connected from the end portion of the grip portion 3 opposite to the mounting portion 2 to the connecting portion 32, and the space from the connecting portion 32 to the inner space 23 is connected. It may be formed as a hollow region 31.
 (3d)例えば、把持部3は、連結部32及び上面部38の少なくとも一方において、意匠面41と非意匠面51とが連結しており、中空領域31が形成されていてもよい。つまり、把持部3は、連結部32のみにおいて、意匠面41と非意匠面51とが連結しており、中空領域31が形成されていてもよいし、上面部38のみにおいて、意匠面41と非意匠面51とが連結しており、中空領域31が形成されていてもよい。 (3d) For example, in the grip portion 3, the design surface 41 and the non-design surface 51 may be connected to each other at at least one of the connecting portion 32 and the upper surface portion 38, and a hollow region 31 may be formed. That is, in the grip portion 3, the design surface 41 and the non-design surface 51 may be connected to each other only in the connecting portion 32, and the hollow region 31 may be formed, or the design surface 41 may be formed only in the upper surface portion 38. The hollow region 31 may be formed by being connected to the non-design surface 51.
 (3e)把持部3は、意匠面41と非意匠面51とは、少なくともこれらの一部において、意匠面41と非意匠面51とが連結した状態で、中空領域31が形成されていたが、意匠面41と非意匠面51とは、連結されていなくてもよい。例えば、ハンドル1は、図示しないが、連結部32及び上面部38を備えなくてもよい。つまり、ハンドル1は、意匠部位4が取付部2に接続され、且つ、非意匠部位5が意匠部位4と略平行に、取付部2に接続されていてもよい。この場合、意匠部位4と非意匠部位5との隙間が中空領域31に相当する。 (3e) In the grip portion 3, the design surface 41 and the non-design surface 51 have a hollow region 31 formed in a state where the design surface 41 and the non-design surface 51 are connected to each other at least in a part thereof. The design surface 41 and the non-design surface 51 may not be connected to each other. For example, although not shown, the handle 1 may not include the connecting portion 32 and the upper surface portion 38.
