Description
本発明は、シール部材を備えて相手コネクタとの嵌合部を防水する防水コネクタに関する。
The present invention relates to a waterproof connector having a seal member for waterproofing a mating portion with a mating connector.
従来より、上記のタイプの防水コネクタが知られている。例えば特許文献１には、防水用のゴムリングをハウジングとフロントリテーナとで嵌合方向両側から挟んだ構造の防水コネクタが開示されている。この特許文献１に開示された防水コネクタを構成するゴムリングには、前方に突き出た回り止めリブが設けられている。また、そのゴムリングをハウジングとの間に挟むフロントリテーナには、その回り止めリブを収容する収容溝が設けられている。そして、ゴムリングの回り止めリブを収容溝に収容することで、ゴムリングの回り止めが図られている。
Conventionally, waterproof connectors of the above type are known. For example, Patent Document 1 discloses a waterproof connector having a structure in which a waterproof rubber ring is sandwiched by a housing and a front retainer from both sides in the fitting direction. The rubber ring constituting the waterproof connector disclosed in Patent Document 1 is provided with a locking rib protruding forward. Moreover, the front retainer which pinches | interposes the rubber ring between housings is provided with the accommodation groove which accommodates the rotation prevention rib. Then, the rubber ring is prevented from rotating by accommodating the detent rib of the rubber ring in the accommodation groove.
上掲の特許文献１の防水コネクタの場合、回り止めリブがフロントリテーナに覆われる構造となっている。このため、組立にあたりゴムリングが回転位置ずれを生じていても、フロントリテーナが障害となり、ゴムリングが回転位置ずれを生じているか否かの検査が困難である。
In the case of the waterproof connector of Patent Document 1 mentioned above, the locking rib is structured to be covered by the front retainer. For this reason, even if the rubber ring is out of rotational position during assembly, the front retainer is an obstacle, and it is difficult to check whether the rubber ring is out of rotational position.
本発明は、上記事情に鑑み、シール部材が回転位置ずれを生じている場合に、それを容易に視認することができる防水コネクタを提供することを目的とする。
An object of this invention is to provide the waterproof connector which can visually recognize visually, when the sealing member has produced rotational position shift in view of the said situation.
上記目的を達成する本発明の防水コネクタは、
一周に亘る側壁面を有するハウジングと、
上記側壁面を一周に亘って取り巻き、相手コネクタとの嵌合時にその側壁面と相手コネクタとの双方に一周に亘って接触して相手コネクタとの嵌合部を防水するシール部材とを備え、
上記ハウジングが、嵌合の向きに関する上記シール部材の前端面に沿う立壁を形成して周回方向に断続的に延びる第１のリブを有し、
上記シール部材が、上記第１のリブが途切れた領域において嵌合の向きに、その嵌合の向きに関し第１のリブと重なる位置まで突き出て周回方向に延びる第２のリブを有することを特徴とする。 The waterproof connector of the present invention which achieves the above object is
A housing having side wall surfaces extending around the circumference;
The side wall surface is surrounded all around, and a sealing member is provided which contacts with both the side wall surface and the mating connector when it is fitted with the mating connector, and waterproofs the fitting portion with the mating connector.
The housing has a first rib extending intermittently in the circumferential direction forming a raised wall along the front end face of the seal member with respect to the direction of fitting;
The seal member has a second rib extending in the circumferential direction so as to protrude to a position overlapping with the first rib in the fitting direction in the fitting direction in the region where the first rib is broken. I assume.
一周に亘る側壁面を有するハウジングと、
上記側壁面を一周に亘って取り巻き、相手コネクタとの嵌合時にその側壁面と相手コネクタとの双方に一周に亘って接触して相手コネクタとの嵌合部を防水するシール部材とを備え、
上記ハウジングが、嵌合の向きに関する上記シール部材の前端面に沿う立壁を形成して周回方向に断続的に延びる第１のリブを有し、
上記シール部材が、上記第１のリブが途切れた領域において嵌合の向きに、その嵌合の向きに関し第１のリブと重なる位置まで突き出て周回方向に延びる第２のリブを有することを特徴とする。 The waterproof connector of the present invention which achieves the above object is
A housing having side wall surfaces extending around the circumference;
The side wall surface is surrounded all around, and a sealing member is provided which contacts with both the side wall surface and the mating connector when it is fitted with the mating connector, and waterproofs the fitting portion with the mating connector.
The housing has a first rib extending intermittently in the circumferential direction forming a raised wall along the front end face of the seal member with respect to the direction of fitting;
The seal member has a second rib extending in the circumferential direction so as to protrude to a position overlapping with the first rib in the fitting direction in the fitting direction in the region where the first rib is broken. I assume.
本発明の防水コネクタにおいて、シール部材に周回方向の位置ずれを生じさせる向きの力が作用したとする。すると、先ずは、第１のリブと第２のリブの端面どうしが干渉する。これにより、シール部材の、周回方向への位置ずれがある程度抑制される。しかしながら、シール部材には、例えばゴム材料等、可撓性あるいは伸縮性を必要とする材料が用いられる。このため、シール部材に周回方向の位置ずれを生じさせる、ある程度大きな力が作用すると、第１のリブの上に第２のリブが乗り上げてシール部材が回転位置ずれを生じることになる。あるいは、シール部材の回転とは別に、シール部材をハウジングに装着するときにシール部材が周回方向に位置ずれを生じた姿勢のまま装着されることもあり得る。いずれの場合であっても、第２のリブが第１のリブの上に乗り上げた姿勢になると、その乗り上げによりシール部材が変形し、その変形を容易に視認することができる。
In the waterproof connector of the present invention, it is assumed that a force in a direction causing positional deviation in the circumferential direction acts on the seal member. Then, first, the end faces of the first rib and the second rib interfere with each other. As a result, the positional deviation of the seal member in the circumferential direction is suppressed to some extent. However, for the sealing member, for example, a material requiring flexibility or elasticity such as a rubber material is used. For this reason, when a large force that causes positional displacement in the circumferential direction is applied to the seal member, the second rib rides on the first rib, causing rotational position displacement of the seal member. Alternatively, separately from the rotation of the seal member, the seal member may be mounted in a posture in which the seal member is displaced in the circumferential direction when the seal member is mounted on the housing. In any case, when the second rib is placed on the first rib, the seal member is deformed by the riding and the deformation can be easily visually recognized.
ここで、本発明の防水コネクタにおいて、
上記側壁面の、シール部材が配置される領域が、嵌合の向きに眺めた時に左右に長い略長円形状を有し、
上記第１のリブが、上記側壁面の上下面に形成され、
上記第２のリブが、その側壁面に沿う略円弧形状に、端面が上記第１のリブの端面と対面する位置まで延びていることが好ましい。 Here, in the waterproof connector of the present invention,
The region of the side wall surface where the seal member is disposed has a substantially oval shape that is long in the left and right when viewed in the fitting direction,
The first ribs are formed on upper and lower surfaces of the side wall surface,
It is preferable that the second rib extends in a substantially arc shape along the side wall surface to a position where the end face faces the end face of the first rib.
上記側壁面の、シール部材が配置される領域が、嵌合の向きに眺めた時に左右に長い略長円形状を有し、
上記第１のリブが、上記側壁面の上下面に形成され、
上記第２のリブが、その側壁面に沿う略円弧形状に、端面が上記第１のリブの端面と対面する位置まで延びていることが好ましい。 Here, in the waterproof connector of the present invention,
The region of the side wall surface where the seal member is disposed has a substantially oval shape that is long in the left and right when viewed in the fitting direction,
The first ribs are formed on upper and lower surfaces of the side wall surface,
It is preferable that the second rib extends in a substantially arc shape along the side wall surface to a position where the end face faces the end face of the first rib.
シール部材にも適度な剛性が必要である。側壁面が略長円形状を有し、シール部材もそれに応じて略長円の環形状に形成されているとする。そして、略長円形状の、ある程度の剛性を持ったシール部材が回転位置ずれを生じて、略円弧形状の第２のリブが略直線形状の第１のリブの上に乗り上げたとする。すると、シール部材の剛性により、そのシール部材が大きく変形する。したがって、この態様の場合、シール部材が回転位置ずれを生じていることが一層明確に視認される。
The sealing member also needs to have appropriate rigidity. It is assumed that the side wall surface has a substantially oval shape, and the seal member is accordingly formed in a substantially oval ring shape. Then, it is assumed that a substantially oval seal member having a certain degree of rigidity causes a rotational positional deviation, and the substantially arc-shaped second rib rides on the substantially linear first rib. Then, the seal member is largely deformed due to the rigidity of the seal member. Therefore, in the case of this aspect, it is more clearly recognized that the seal member has a rotational displacement.
また、本発明の防水コネクタにおいて、上記シール部材が周回方向の力を受けた時に上記第２のリブが上記第１のリブに乗り上げるだけの、第１のリブの高さおよびシール部材の可撓性あるいは伸縮性を有することが好ましい。
In the waterproof connector according to the present invention, the height of the first rib and the flexibility of the seal member are such that the second rib rides on the first rib when the seal member receives a circumferential direction force. It is preferable to have elasticity or elasticity.
本発明は、第１のリブと第２のリブの端面どうしの干渉による回り止め抑制の作用がほとんど期待できない程度の可撓性あるいは伸縮性を有するシール部材を採用した場合にも適用することができる。この場合であっても、第１のリブの上に第２のリブが乗り上げることにより生じるシール部材の変形を視認することで、シール部材の回転位置ずれを容易に知ることができる。
The present invention may be applied to the case where a seal member having flexibility or stretchability to such an extent that the effect of suppressing the detent due to the interference between the end faces of the first rib and the second rib is hardly expected is adopted. it can. Even in this case, it is possible to easily know the rotational position shift of the seal member by visually recognizing the deformation of the seal member caused by the second rib running on the first rib.
以上の本発明の防水コネクタによれば、シール部材が回転位置ずれを生じた場合に、それを容易に視認することができる。
According to the waterproof connector of the present invention as described above, when the sealing member is displaced in rotational position, it can be easily visually recognized.
以下、本発明の実施の形態について説明する。
Hereinafter, embodiments of the present invention will be described.
図１は、本発明の一実施形態としての防水コネクタの斜視図である。
FIG. 1 is a perspective view of a waterproof connector according to an embodiment of the present invention.
また、図２は、図１に斜視図を示した防水コネクタの分解斜視図である。
FIG. 2 is an exploded perspective view of the waterproof connector whose perspective view is shown in FIG.
この防水コネクタ１０は、図２に示すように、コネクタ本体２０とシール部材３０とを備えている。コネクタ本体２０は、回路基板２１と樹脂ハウジング２２とを有する。そして、このコネクタ本体２０は、不図示の相手コネクタとの嵌合の向き（図１に示す矢印Ｘの向き）の先端部に、回路基板２１の先端部を露出させている。この回路基板２１の露出した先端部には、プリント配線で形成された接続パッド２１１が並んでいる。それらの接続パッド２１１は、相手コネクタ（不図示）に備えられている弾性接触端子と電気的に接続される端子として作用する。
As shown in FIG. 2, the waterproof connector 10 includes a connector body 20 and a seal member 30. The connector main body 20 has a circuit board 21 and a resin housing 22. Then, the front end portion of the circuit board 21 is exposed at the front end portion of the connector main body 20 in the fitting direction (direction of the arrow X shown in FIG. 1) with the mating connector (not shown). At the exposed end of the circuit board 21, connection pads 211 formed of printed wiring are arranged. The connection pads 211 function as terminals electrically connected to elastic contact terminals provided on a mating connector (not shown).
また、樹脂ハウジング２２は、この回路基板２１の、接続パッド２１１が配列された先端部を除いた残りの全体を、その回路基板２１に搭載されている回路部品（不図示）も一緒に覆っている。この樹脂ハウジング２２は、本発明にいうハウジングの一例に相当する。
In addition, the resin housing 22 covers the entire remaining portion of the circuit board 21 except for the end portion where the connection pads 211 are arranged, together with the circuit components (not shown) mounted on the circuit board 21. There is. The resin housing 22 corresponds to an example of the housing according to the present invention.
露出した回路基板２１の先端部に隣接した樹脂ハウジング２２の先端部には、窪み部２２１が形成されている。この窪み部２２１は、相手コネクタとの半嵌合状態での仮係止を担っている。また、この樹脂ハウジング２２の、シール部材３０が配置されている領域よりもさらに後方には、ボス２２２が設けられている。このボス２２２は、相手コネクタとの嵌合の際に相手コネクタのカム溝（不図示）に入り込んで、カムの作用による相手コネクタとの嵌合を助ける役割を担っている。これらの窪み部２２１やボス２２２は、本発明の特徴部分とは無関係なので、これ以上の説明は割愛する。
A recess 221 is formed at the end of the resin housing 22 adjacent to the exposed end of the circuit board 21. The recessed portion 221 is in charge of temporary engagement in a semi-fitted state with the mating connector. Further, a boss 222 is provided further to the rear of the area of the resin housing 22 in which the seal member 30 is disposed. The boss 222 enters the cam groove (not shown) of the mating connector when mating with the mating connector, and plays a role in assisting the mating with the mating connector by the action of the cam. These depressions 221 and bosses 222 are irrelevant to the features of the present invention, and thus further description is omitted.
樹脂ハウジング２２は、シール部材３０が配置される、一周に亘る側壁面２２３を有する。この側壁面２２３の、シール部材３０が配置される領域は、嵌合の向き（図１に示す矢印Ｘの向き）とは逆向きに眺めたときに左右に長い略長円形状を有する。シール部材３０も、この側壁面２２３の略長円形状に応じた、略長円の環形状に形成されている。このシール部材３０は、外力の作用がない時には、図２に示す略長円形状をほぼ維持する程度の剛性を有し、かつ、必要な可撓性および伸縮性を有するゴム材料からなる部材である。このシール部材３０は、樹脂ハウジング２２の側壁面２２３を一周に亘って取り巻くように配置される。
The resin housing 22 has a circumferential side wall 223 on which the sealing member 30 is disposed. The region of the side wall surface 223 where the seal member 30 is disposed has a substantially oval shape that is long in the left and right when viewed in the direction opposite to the fitting direction (the direction of the arrow X shown in FIG. 1). The sealing member 30 is also formed in a substantially oval ring shape corresponding to the substantially oval shape of the side wall surface 223. The seal member 30 is a member made of a rubber material having a rigidity enough to substantially maintain the substantially oval shape shown in FIG. 2 when there is no action of external force, and having necessary flexibility and stretchability. is there. The seal member 30 is disposed so as to surround the side wall surface 223 of the resin housing 22 over the entire circumference.
不図示の相手コネクタには、この防水コネクタ１０の、シール部材３０が配置されている部分を含む、それよりも先端の部分を受容する嵌合空間が形成されている。この防水コネクタ１０が相手コネクタと嵌合すると、シール部材３０は、この防水コネクタ１０の側壁面２２３と、相手コネクタの、嵌合空間を区画している内壁面との双方に一周に亘って接触する。このシール部材３０は、このようにして、この防水コネクタ１０と相手コネクタとの嵌合部を防水する。
The mating connector (not shown) is formed with a fitting space for receiving the tip portion of the waterproof connector 10 including the portion where the seal member 30 is disposed. When the waterproof connector 10 is engaged with the mating connector, the seal member 30 contacts the side wall surface 223 of the waterproof connector 10 and the inner wall surface of the mating connector defining the mating space over the entire circumference. Do. Thus, the seal member 30 waterproofs the fitting portion between the waterproof connector 10 and the mating connector.
図３、図４、および、図５は、図１に斜視図を示した防水コネクタの、それぞれ平面図、側面図、および、嵌合の向きの前方から眺めた正面図である。
FIGS. 3, 4 and 5 are a plan view, a side view and a front view of the direction of fitting of the waterproof connector whose perspective view is shown in FIG. 1, respectively.
ここでは、図１および図２に加え、さらに図３～図５を参照しながら、本実施形態の特徴部分について説明する。
Here, the characteristic parts of the present embodiment will be described with reference to FIGS. 3 to 5 in addition to FIGS. 1 and 2.
この防水コネクタ１０と相手コネクタとの嵌合部が確実に防水されるには、シール部材３０が樹脂ハウジング２２の正しい位置に正しい姿勢で配置される必要がある。まず第１には、このシール部材３０を嵌合方向について正しい位置に配置してその位置を維持する必要がある。このために、樹脂ハウジング２２の、シール部材３０が配置される側壁面２２３の直ぐ後方に、立壁２２４が設けられている。これにより、側壁面２２３に配置されているシール部材３０の、嵌合の向きの後方への移動が阻止されている。また、側壁面２２３に配置されているシール部材３０の、嵌合の向きの前端面に沿う位置には、リブ２２５が設けられている。このリブ２２５は、側壁面２２３に立壁を形成する向き、すなわち外向きに突き出て、周回方向に断続的に延びている。本実施形態の防水コネクタ１０の場合、このリブ２２５は、略長円形状の側壁面２２３の上面と下面に直線的に延びるように形成されている。そして、このリブ２２５は、上下面の端部付近で途切れ、左右の略円弧形状の部分２２３ａには形成されていない。ただし、このリブ２２５は、上下面においても断続的に途切れていてもよく、左右の略円弧形状の部分の一部にも形成されていてもよい。このリブ２２５は、本発明にいう第１のリブの一例に相当する。側壁面２２３に配置されているシール部材３０は、このリブ２２５により、嵌合の向きの前方への移動が阻止されている。シール部材３０は、このように、立壁２２４とリブ２２５とにより、嵌合方向の位置が規制されている。
In order to ensure that the fitting portion between the waterproof connector 10 and the mating connector is waterproofed, the seal member 30 needs to be disposed at the correct position of the resin housing 22 in the correct posture. First of all, it is necessary to place the seal member 30 at the correct position in the fitting direction and maintain the position. For this purpose, an upright wall 224 is provided immediately behind the side wall surface 223 of the resin housing 22 on which the seal member 30 is disposed. Thereby, the rearward movement of the fitting direction of the seal member 30 disposed on the side wall surface 223 is prevented. Further, a rib 225 is provided at a position along the front end face in the fitting direction of the seal member 30 disposed on the side wall surface 223. The rib 225 is directed to form a standing wall on the side wall surface 223, that is, protrudes outward and intermittently extends in the circumferential direction. In the case of the waterproof connector 10 according to the present embodiment, the rib 225 is formed to extend linearly on the upper surface and the lower surface of the substantially oval side wall surface 223. And this rib 225 is cut off near the end of the upper and lower surface, and is not formed in the part 223a of the approximately circle shape of the right and left. However, the ribs 225 may be interrupted intermittently also in the upper and lower surfaces, or may be formed in part of the left and right substantially arc-shaped portions. The rib 225 corresponds to an example of the first rib in the present invention. The seal member 30 disposed on the side wall surface 223 is prevented by the ribs 225 from moving forward in the fitting direction. Thus, the position of the sealing member 30 in the fitting direction is regulated by the standing wall 224 and the rib 225.
シール部材３０は、嵌合方向の位置が規制されているだけでは不十分である。このシール部材３０が嵌合方向には正しい位置に配置されていても、周回方向に回転位置ずれを生じる場合がある。このシール部材３０は、円形ではなく図２に示すように略長円形状であって、その形状をほぼ保つためのある程度の剛性を持っている。このため、このシール部材３０が周回方向に位置ずれを生じた姿勢のままの場合、確実な防水性能を発揮できないおそれがある。すなわち、嵌合にあたっては、このシール部材３０が、嵌合方向に正しい位置に配置されているとともに、周回方向にも位置ずれのない姿勢に配置されている必要がある。このためには、シール部材３０が周回方向に位置ずれを生じていないかどうかを容易に検査できる必要がある。
The sealing member 30 is not sufficient only by restricting the position in the fitting direction. Even if the seal member 30 is disposed at the correct position in the fitting direction, rotational positional deviation may occur in the circumferential direction. The seal member 30 is not circular but has a substantially oval shape as shown in FIG. 2 and has a certain degree of rigidity to substantially maintain its shape. For this reason, there is a possibility that a certain waterproof performance can not be exhibited when the seal member 30 remains in the position where the positional deviation occurs in the circumferential direction. That is, in the fitting, the seal member 30 needs to be disposed at a correct position in the fitting direction and in a posture free from positional deviation in the circumferential direction. For this purpose, it is necessary to be able to easily inspect whether the seal member 30 is not displaced in the circumferential direction.
本実施形態の場合、これを実現するために、シール部材３０にもリブ３１を設けている。このリブ３１は、樹脂ハウジング２２に設けられている、周回方向に断続的に延びるリブ２２５が途切れた領域において、嵌合の向きに突き出ている。そして、このリブ３１は、嵌合の向きに関し、樹脂ハウジング２２と重なる位置まで突き出ている。本実施形態では、樹脂ハウジング２２に形成されているリブ２２５は、側壁面２２３のうちの上面と下面に直線的に延びるように設けられている。そして、このリブ２２５は、上下面の端部付近で途切れ、左右の略円弧形状の部分２２３ａには形成されていない。そこで、本実施形態では、このリブ３１は、樹脂ハウジング２２に設けられているリブ２２５が途切れている左右の略円弧形状の領域に沿うように、略円弧形状に形成されている。
In the case of this embodiment, in order to realize this, the sealing member 30 is also provided with the rib 31. The rib 31 protrudes in the fitting direction in a region where the rib 225 provided in the resin housing 22 and intermittently extending in the circumferential direction is broken. And this rib 31 protrudes to the position which overlaps with the resin housing 22 regarding the direction of fitting. In the present embodiment, the ribs 225 formed on the resin housing 22 are provided so as to extend linearly on the upper surface and the lower surface of the side wall surface 223. And this rib 225 is cut off near the end of the upper and lower surface, and is not formed in the part 223a of the approximately circle shape of the right and left. So, in this embodiment, this rib 31 is formed in a substantially circular arc shape along the area | region of the substantially circular arc shape on either side which the rib 225 provided in the resin housing 22 has interrupted.
図６は、図５の円Ｒの部分の拡大図（Ａ）、および円Ｒの部分の、シール部材が周回方向に位置ずれを生じた場合の模式図（Ｂ）である。この図６においては、分かり易さのため、シール部材３０には、ハッチングが付されている。
FIG. 6 is an enlarged view (A) of the portion of the circle R in FIG. 5 and a schematic view (B) of the portion of the circle R when the seal member is displaced in the circumferential direction. In FIG. 6, the seal member 30 is hatched for easy understanding.
図６（Ａ）には、周回方向に位置ずれを生じていない、正しい姿勢にあるときのシール部材３０が示されている。この正しい姿勢の場合、樹脂ハウジング２２に形成されたリブ２２５の端面２２５ａと、シール部材３０に形成されたリブ３１の端面３１ａが互いに対面した位置にある。
FIG. 6A shows the seal member 30 when it is in the correct posture, with no positional displacement in the circumferential direction. In this correct posture, the end face 225a of the rib 225 formed on the resin housing 22 and the end face 31a of the rib 31 formed on the seal member 30 are at positions facing each other.
この正しい姿勢にあるシール部材３０に、図６（Ｂ）に矢印Ｓで示す、シール部材３０を回転方向に回転させる向きの力が作用したとする。すると、先ずは、リブ２２５の端面２２５ａにリブ３１の端面３１ａが突き当たる。これにより、極めて弱い力であれば端面２２５ａ，３１ａどうしの突き当てが回転止めとして作用する可能性がある。ただし、シール部材３０は、可撓性および伸縮性を有する。このため、シール部材に、矢印Ｓの向きの、その極めて弱い力を越える力が作用すると、シール部材３０のリブ３１が樹脂ハウジングのリブ２２５の上に容易に乗り上げる。あるいは、矢印Ｓの向きへの力の作用とは別に、コネクタ本体２０にシール部材３０を装着するときに、シール部材３０が周回方向に位置ずれを生じた姿勢のまま装着されることもあり得る。
It is assumed that a force in the direction shown by the arrow S in FIG. 6B for rotating the seal member 30 in the rotational direction acts on the seal member 30 in the correct posture. Then, first, the end face 31 a of the rib 31 abuts on the end face 225 a of the rib 225. Thus, the abutment of the end faces 225a and 31a may act as a rotation stopper if the force is extremely weak. However, the seal member 30 has flexibility and stretchability. Therefore, when a force exceeding the extremely weak force in the direction of the arrow S acts on the seal member, the rib 31 of the seal member 30 easily rides over the rib 225 of the resin housing. Alternatively, when the seal member 30 is attached to the connector main body 20 separately from the action of the force in the direction of the arrow S, the seal member 30 may be attached with the position deviated in the circumferential direction. .
いずれにしろ、シール部材３０が、図６（Ｂ）に示すように、周回方向に位置ずれを生じた姿勢になると、シール部材３０に、リブ３１がリブ２２５に乗り上げたことによる変形が生じる。この変形は、一目で容易に視認することができる。すなわち、シール部材３０が周回方向の位置ずれのない正しい姿勢にあるか否かを容易に検査することができる。特に、本実施形態の場合、シール部材３０は、図２に示す略長円形状に形成されていて、その形状をある程度保つだけの剛性を有する。このため、このシール部材３０が、図６（Ｂ）に示すように周回方向に位置ずれを生じると、その変形量が大きくあらわれ、シール部材３０が異形となっていることが一層容易に視認される。
In any case, as shown in FIG. 6 (B), when the seal member 30 is in the position where the positional deviation occurs in the circumferential direction, the seal member 30 is deformed due to the rib 31 riding on the rib 225. This deformation is easily visible at a glance. That is, it can be easily inspected whether or not the seal member 30 is in the correct posture without positional deviation in the circumferential direction.
