　１実施形態では、
　上記膨出した凸部は、上記リード線を囲むように環状に連なっている。 In one embodiment,
The bulged convex portion is continuous in an annular shape so as to surround the lead wire.
　上記実施形態によれば、上記膨出した凸部が、上記リード線を囲むように環状に連なっているので、この切れ目のない環状の膨出した凸部によって、水がハウジング内に侵入するのを確実に防止でき、ひいては、水がリード線に沿って内部に侵入するのを防止できる。 According to the above embodiment, the bulged convex portion is formed in a ring shape so as to surround the lead wire, so that water penetrates into the housing by the continuous bulged convex portion. Thus, water can be prevented from entering the inside along the lead wire.
　１実施形態では、
　上記貫通穴の延在する方向の上記ハウジングの長さが、上記貫通穴の延在する方向の上記挿入部材の長さよりも長くて、上記ハウジングの下部の内周面と上記挿入部材の下端面とによって、凹部が形成されている。 In one embodiment,

　以下、この発明を図示の実施形態により詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
　（第１実施形態）
　この発明の第１実施形態のブッシングは、図１に示すように、略角筒形状のハウジング１と、このハウジング１の略矩形の貫通穴２に矢印Ｘ方向に挿入される略板状の挿入部材２０とからなる。上記ハウジング１の貫通穴２の内面と挿入部材２０の外面とで図３および５に示すようにリード線３０，３０，３０を保持している。上記ハウジング１と挿入部材２０とは樹脂から作製している。 (First embodiment)
As shown in FIG. 1, the bushing according to the first embodiment of the present invention is a substantially plate-like insertion inserted into a substantially rectangular tube-shaped housing 1 and a substantially rectangular through hole 2 of the housing 1 in the direction of arrow X. And the member 20. As shown in FIGS. 3 and 5, lead wires 30, 30, 30 are held by the inner surface of the through hole 2 of the housing 1 and the outer surface of the insertion member 20. The housing 1 and the insertion member 20 are made of resin.
　図１に示すように、上記ハウジング１の外周面には継ぎ目が無い一方、上記ハウジング１の内周面のランド部３には、第１保持部としての断面略円弧状の溝５，５，５有する。この円弧状の溝５，５，５は、湾曲した凹部の一例である。一方、上記挿入部材２０の外面の片側には、第２保持部としての断面略円弧状の溝２５，２５，２５有する。この円弧状の溝２５，２５，２５は、湾曲した凹部の一例である。 As shown in FIG. 1, the outer peripheral surface of the housing 1 has no seam, while the land portion 3 on the inner peripheral surface of the housing 1 has grooves 5, 5 having a substantially arcuate cross section as a first holding portion. 5 These arc-shaped grooves 5, 5, and 5 are examples of curved concave portions. On the other hand, on one side of the outer surface of the insertion member 20, grooves 25, 25, 25 serving as second holding portions having a substantially circular arc cross section are provided. The arc-shaped grooves 25, 25, 25 are an example of a curved recess.
　上記ハウジング１の内周面の略円弧状の溝５，５，５と挿入部材２０の外面の略円弧状の溝２５，２５，２５とは対向して、三本のリード線３０，３０，３０を確実に把持するようになっている。 The substantially arc-shaped grooves 5, 5, 5 on the inner peripheral surface of the housing 1 and the substantially arc-shaped grooves 25, 25, 25 on the outer surface of the insertion member 20 face each other, so that three lead wires 30, 30, 30 is securely gripped.
　また、図２および３に示すように、上記ハウジング１の内面の略円弧状の溝５，５，５の上側の部分５ａ，５ａ，５ａと下側の部分５ｂ，５ｂ，５ｂとの間には、略矩形の凹所１７を設けている。この凹所１７の深さは、図３に示すように、略円弧状の溝５，５，５の深さよりも大きな深さを有し、凹所１７の内面はリード線３０，３０，３０に接触しないようになっている。また、図１および４に示すように、上記挿入部材２０の外面の断面略円弧状の溝２５，２５，２５の上側の部分２５ａ，２５ａ，２５ａと下側の部分２５ｂ，２５ｂ，２５ｂとの間には、略矩形の凹所２７を設けている。この凹所２７の深さは、図３に示すように、略円弧状の溝２５，２５，２５の深さよりも大きな深さを有し、凹所２７の内面はリード線３０，３０，３０に接触しないようになっている。この凹所１７と２７とで、縁切り用の空隙３７を形成して、リード線３０，３０，３０を伝わってきた水をこの縁切り用の空隙３７で遮断して、水が内部に侵入するのを防止するようにしている。 2 and 3, between the upper portions 5a, 5a, 5a of the substantially arc-shaped grooves 5, 5, 5 on the inner surface of the housing 1 and the lower portions 5b, 5b, 5b. Is provided with a substantially rectangular recess 17. As shown in FIG. 3, the depth of the recess 17 is greater than the depth of the substantially arc-shaped grooves 5, 5, 5, and the inner surface of the recess 17 has lead wires 30, 30, 30. It is supposed not to touch. As shown in FIGS. 1 and 4, the grooves 25, 25, 25 on the outer surface of the insertion member 20 have substantially circular arc-shaped grooves 25, 25, 25 and upper portions 25a, 25a, 25a and lower portions 25b, 25b, 25b. A substantially rectangular recess 27 is provided between them. As shown in FIG. 3, the depth of the recess 27 has a depth larger than the depth of the substantially arc-shaped grooves 25, 25, 25, and the inner surface of the recess 27 has lead wires 30, 30, 30. It is supposed not to touch. The recesses 17 and 27 form an edge-cutting gap 37, and the water transmitted through the lead wires 30, 30, and 30 is blocked by the edge-cutting gap 37, so that water enters the inside. Try to prevent.
　また、上記貫通穴２の幅方向の両側には、図１および２に示すように、係合部に一例としての略矩形の係合穴６，６を設けている。上記係合穴６，６は、図２から分かるように、ハウジング１の内面の片側の上部の両側に位置している。一方、図１に示すように、上記挿入部材２０の外面の片側の上部の両側に係合部の一例としての略矩形の係合凸部２６，２６を設けている。この係合穴６，６と係合凸部２６，２６との貫通穴２の貫通方向の係合によって、挿入部材２０がハウジング１の貫通穴２から下方に脱落しないようになっている。 Further, on both sides of the through hole 2 in the width direction, as shown in FIGS. 1 and 2, substantially rectangular engagement holes 6 and 6 as an example are provided in the engagement portion. As can be seen from FIG. 2, the engagement holes 6 and 6 are located on both sides of the upper portion on one side of the inner surface of the housing 1. On the other hand, as shown in FIG. 1, substantially rectangular engaging convex portions 26, 26 as an example of engaging portions are provided on both sides of the upper portion on one side of the outer surface of the insertion member 20. Due to the engagement of the engagement holes 6, 6 and the engagement projections 26, 26 in the penetration direction of the through hole 2, the insertion member 20 is prevented from dropping downward from the through hole 2 of the housing 1.
　なお、ハウジング１および挿入部材２０に設ける係合部は、上述の係合穴６と係合凸部１６に限らず、係合凸部と係合穴であってもよく、また、係合部の形状は矩形に限らず、係合するならばどのような形状であってもよい。 In addition, the engaging part provided in the housing 1 and the insertion member 20 is not limited to the above-described engaging hole 6 and the engaging convex part 16, and may be an engaging convex part and an engaging hole. The shape is not limited to a rectangle, and may be any shape as long as it is engaged.
　また、図２，３，５，６に示すように、上記ハウジング１の下部１０側の端には、下方に膨出した凸部１１を有し、この下方に膨出した凸部１１によって、ハウジング１の外面を伝わって下降する水を下方に案内してハウジング１から落下させて、ハウジング１内に侵入しないようにしている。より詳しくは、図６に示すように、下方に膨出した凸部１１のハウジング１の外周面側の部分１１ａによって、ハウジング１の外周面に沿って落下してくる水滴Ｗは膨出部１１の先端１１ｃに向けて案内され、この先端１１ｃからハウジング１１と分離して、落下する。一方、下方に膨出した凸部１１のハウジング１の内周面側の部分１１ｂは先端１１ｃから上り曲面になっているから、内周面側の部分１１ｂに沿って水滴Ｗが上昇するのは重力に抗することになって、水滴Ｗはハウジング１内に入り難い。したがって、この下方に膨出した凸部１１によって、水滴がハウジング１の内周面側に入るのを防止できる。 As shown in FIGS. 2, 3, 5, and 6, the end of the housing 1 on the lower portion 10 side has a convex portion 11 that bulges downward. The water descending along the outer surface of the housing 1 is guided downward and dropped from the housing 1 so as not to enter the housing 1. More specifically, as shown in FIG. 6, the water droplet W falling along the outer peripheral surface of the housing 1 is caused to bulge by the portion 11 a on the outer peripheral surface side of the housing 1 of the convex portion 11 bulging downward. It is guided toward the front end 11c, and it is separated from the housing 11 from the front end 11c and falls. On the other hand, since the portion 11b on the inner peripheral surface side of the housing 1 of the convex portion 11 bulging downward is an upward curved surface from the tip 11c, the water droplet W rises along the portion 11b on the inner peripheral surface side. The water droplet W is unlikely to enter the housing 1 because it resists gravity. Therefore, it is possible to prevent water droplets from entering the inner peripheral surface side of the housing 1 by the convex portion 11 bulging downward.
　なお、下方に膨出した凸部１１は断面円弧状に限らず、断面楕円形状、断面放物線形状、段面双曲線形状等であってもよく、湾曲して突出する断面形状ならばどのような形状であってもよい。 Note that the convex portion 11 bulging downward is not limited to a circular arc shape in cross section, and may be an elliptical cross section, a parabolic cross section, a stepped hyperbolic shape, etc. It may be.
　また、上記膨出した凸部１１は、ハウジング１の下端面全体に環状に連なって、リード線３０，３０，３０を囲んでいる。 Further, the bulged convex portion 11 is connected to the entire lower end surface of the housing 1 in a ring shape and surrounds the lead wires 30, 30, 30.
　このように、環状の膨出した凸部１１が切れ目無く、リード線３０，３０，３０全体を囲んでいるので、ハウジング１１の外面に沿って下降する水がハウジング１の内側に侵入するのを確実に防止しながら、ハウジング１から水滴Ｗを下方に案内して落下させることができる。 In this way, since the annular bulged convex portion 11 is seamless and surrounds the entire lead wires 30, 30, 30, the water descending along the outer surface of the housing 11 can enter the inside of the housing 1. The water droplet W can be guided downward from the housing 1 and dropped while reliably preventing.
　一方、図１に示すように、上記ハウジング１の高さ、つまり、貫通穴２の延在する方向のハウジング１の長さは、上記貫通穴２の延在する方向の挿入部材２０の長さ（つまり、挿入部材２０の矢印Ｘで示す挿入方向の長さ）よりも長くて、図３，５および６に示すように、上記ハウジング１の下部１０の内周面と挿入部材２０の下端面２１とによって、凹部８を形成している。 On the other hand, as shown in FIG. 1, the height of the housing 1, that is, the length of the housing 1 in the direction in which the through hole 2 extends, is the length of the insertion member 20 in the direction in which the through hole 2 extends. As shown in FIGS. 3, 5 and 6, the inner peripheral surface of the lower portion 10 of the housing 1 and the lower end surface of the insertion member 20 are longer than (that is, the length of the insertion member 20 in the insertion direction indicated by the arrow X). 21 forms a recess 8.
　そのため、図６に示すように、上記凹部８を下向きにすると、ハウジング１の外周面に付着した水滴Ｗは、凹部８の内面に沿って重力に抗して上昇することが殆どない。したがって、上記凹部８の存在によって、より確実に、水滴Ｗをハウジング１の内側に侵入させること無く、滴下させることができるようになっている。 Therefore, as shown in FIG. 6, when the concave portion 8 is directed downward, the water droplet W attached to the outer peripheral surface of the housing 1 hardly rises against gravity along the inner surface of the concave portion 8. Therefore, the presence of the recess 8 allows the water droplet W to be dropped more reliably without entering the inside of the housing 1.
　上記構成のブッシングにおいては、図１の矢印Ｘに示すように、ハウジング１の貫通穴２の内面の第１保持部の一例としての断面略円弧状の溝５，５，５にリード線３０，３０，３０を保持または搭載した状態で、挿入部材２０の第２保持部の一例としての断面略円弧状の溝２５，２５，２５をリード線３０，３０，３０に案内させつつ、挿入部材２０をハウジング１の貫通穴２内に挿入して、挿入部材２０の係合凸部２６をハウジング１の係合穴６に係合して、ハウジング１に挿入部材２０を組み付ける。 In the bushing having the above-described configuration, as shown by an arrow X in FIG. 1, the lead wires 30, 5, 5, which are examples of the first holding portion on the inner surface of the through hole 2 of the housing 1, The insertion member 20 is guided while the grooves 25, 25, 25 having a substantially arc-shaped cross section as an example of the second holding portion of the insertion member 20 are guided to the lead wires 30, 30, 30 in a state where the 30, 30 is held or mounted. Is inserted into the through hole 2 of the housing 1, the engaging convex portion 26 of the inserting member 20 is engaged with the engaging hole 6 of the housing 1, and the inserting member 20 is assembled to the housing 1.
　このとき、上記ハウジング１および挿入部材２０は樹脂からなるので、挿入部材２０の断面略円弧状の溝２５，２５，２５のリード線３０の絶縁被覆膜による摩擦抵抗は過度に大きくなくて、挿入部材２０はハウジング１の貫通穴２内にスムーズに組み付けることができる。 At this time, since the housing 1 and the insertion member 20 are made of resin, the frictional resistance due to the insulating coating film of the lead wires 30 of the grooves 25, 25, 25 having a substantially arc-shaped cross section of the insertion member 20 is not excessively large. The insertion member 20 can be assembled smoothly into the through hole 2 of the housing 1.
　もし、ハウジングおよび挿入部材がゴム製であると、ゴムの弾性およびそのリード線に対する摩擦抵抗によって、ハウジング内に挿入部材を容易に挿入することができない場合がある。 If the housing and the insertion member are made of rubber, the insertion member may not be easily inserted into the housing due to the elasticity of the rubber and the frictional resistance against the lead wire.
　また、上記挿入部材２０とハウジング１とは、係合凸部２６と係合穴６との係合によって一体化しているので、挿入部材２０がハウジング１の下方に突出したり、下方に脱落したりすることがない。 Further, since the insertion member 20 and the housing 1 are integrated by the engagement of the engagement convex portion 26 and the engagement hole 6, the insertion member 20 protrudes below the housing 1 or falls downward. There is nothing to do.
　また、上記リード線３０，３０，３０はハウジング１の貫通穴２の内面と、その貫通穴２内に挿入された挿入部材２０の外面とによって保持されて、ハウジング１の外周囲に継ぎ目が無いから、このハウジング１の外周面に付着した水滴等がハウジング１内に侵入するのを防止できる。 The lead wires 30, 30, 30 are held by the inner surface of the through hole 2 of the housing 1 and the outer surface of the insertion member 20 inserted into the through hole 2, so that there is no seam around the outer periphery of the housing 1. Therefore, it is possible to prevent water droplets or the like adhering to the outer peripheral surface of the housing 1 from entering the housing 1.
　したがって、このブッシングを用いたモータ内に水が浸入するのを防止できる。 Therefore, it is possible to prevent water from entering the motor using this bushing.
　また、上記第１保持部および第２保持部は、例えば、断面略円弧状の溝５，５，５；２５，２５，２５である湾曲した凹部であるから、リード線３０，３０，３０を隙間無く確実に把持することができる。 Moreover, since the said 1st holding | maintenance part and the 2nd holding | maintenance part are the curved recessed parts which are the groove | channels 5, 5, 5; It can be securely gripped without a gap.
　特に、この第１実施形態では、上記ハウジング１の内面の第１保持部としての湾曲した凹部の一例である断面略円弧状の溝５，５，５と、上記挿入部材２０の外面の第２保持部としての湾曲した凹部の一例である断面略円弧状の溝２５，２５，２５とは、互いに対向して三本のリード線３０，３０，３０を保持しているから、三本のリード線３０，３０，３０を極めて確実に隙間なく把持することができる。 In particular, in the first embodiment, the grooves 5, 5, and 5 having a substantially arcuate cross section as an example of a curved recess as the first holding portion on the inner surface of the housing 1, and the second outer surface of the insertion member 20 are provided. The grooves 25, 25, 25, which are examples of curved concave portions as the holding portions, hold the three lead wires 30, 30, 30 facing each other, so that the three leads The wires 30, 30, 30 can be gripped very reliably without gaps.
　しかも、これらの断面略円弧状の溝５，５，５と断面略円弧状の溝２５，２５，２５とは、外周囲に継ぎ目が無いハウジング１内に収容されていて、外部に露出することがないから、水がこれらの箇所に侵入し難い。 Moreover, the grooves 5, 5, and 5 having a substantially arc-shaped cross section and the grooves 25, 25, and 25 having a substantially arc-shaped cross section are accommodated in the housing 1 having no joints on the outer periphery and exposed to the outside. Since there is no water, it is difficult for water to enter these places.
　さらにまた、図２，３，５，６に示すように、上記ハウジング１の下部１０側の端面は下方に膨出した凸部１１になっているから、この下方に膨出した凸部１１によって、ハウジング１の外面を伝わって下降する水を下方に案内してハウジング１から落下させて、ハウジング内に侵入しないようにすることができる。より詳しくは、図６に示すように、下方に膨出した凸部１１のハウジング１の外周面側の部分１１ａによって、ハウジング１の外周面に沿って落下してくる水滴Ｗは膨出部１１の先端１１ｃに向けて案内されて、この先端１１ｃからハウジング１と分離して、落下する一方、下方に膨出した凸部１１のハウジング１の内周面側の部分１１ｂは先端１１ｃから上り曲面になっているから、内周面側の部分１１ｂに沿って上昇するのは重力に抗することになって、水滴Ｗがハウジング１内に入り難い。 Furthermore, as shown in FIGS. 2, 3, 5, and 6, the lower end 10 side end surface of the housing 1 is a convex portion 11 that bulges downward. The water descending along the outer surface of the housing 1 can be guided downward and dropped from the housing 1 so as not to enter the housing. More specifically, as shown in FIG. 6, the water droplet W falling along the outer peripheral surface of the housing 1 is caused to bulge by the portion 11 a on the outer peripheral surface side of the housing 1 of the convex portion 11 bulging downward. The portion 11b on the inner peripheral surface of the housing 1 of the convex portion 11 bulging downward is separated from the housing 11 from the tip 11c and dropped from the tip 11c. Therefore, ascending along the portion 11 b on the inner peripheral surface side resists gravity, and the water droplets W hardly enter the housing 1.
　したがって、この下方に膨出した凸部１１によって、水滴がハウジング１内に入るのを確実に防止できる。 Therefore, it is possible to reliably prevent water droplets from entering the housing 1 by the convex portion 11 bulging downward.
　さらに、上記膨出した凸部１１は、ハウジング１の下端面全体に環状に切れ目無く連なって、リード線３０，３０，３０全体を囲んでいるので、ハウジング１の外面に沿って下降する水を、ハウジング１の内側に侵入することを確実に防止しながら、ハウジング１から水滴Ｗを下方に案内して落下させることができる。 Further, since the bulged convex portion 11 is continuously connected to the entire lower end surface of the housing 1 in an annular manner and surrounds the entire lead wires 30, 30, 30, the water that descends along the outer surface of the housing 1 is allowed to flow. The water droplet W can be guided and dropped from the housing 1 while reliably preventing the inside of the housing 1 from entering.
　また、上記ハウジング１の高さ、つまり、貫通穴２の延在する方向のハウジング１の長さは、上記挿入部材２０の貫通穴２の延在する方向の長さよりも長くて、図３，５および６に示すように、上記ハウジング１の下部１０の内周面と挿入部材２０の下端面２１とによって、凹部８を形成しているから、この凹部８を図６に示すように、下向きにすると、ハウジング１の外周面に付着した水滴Ｗは、凹部８の内面に沿って重力に抗して上昇することが殆どない。したがって、上記凹部８の存在によって、より確実に、水滴Ｗをハウジング１の内側に侵入させること無く、滴下させることができる。 Further, the height of the housing 1, that is, the length of the housing 1 in the direction in which the through hole 2 extends is longer than the length in the direction in which the through hole 2 of the insertion member 20 extends. As shown in FIGS. 5 and 6, since the recess 8 is formed by the inner peripheral surface of the lower portion 10 of the housing 1 and the lower end surface 21 of the insertion member 20, the recess 8 faces downward as shown in FIG. Then, the water droplets W attached to the outer peripheral surface of the housing 1 hardly rises against the gravity along the inner surface of the recess 8. Therefore, the presence of the recess 8 allows the water droplet W to be dropped more reliably without entering the inside of the housing 1.
　また、図２および３に示すように、上記ハウジング１の内面の略円弧状の溝５，５，５の上側の部分５ａ，５ａ，５ａと下側の部分５ｂ，５ｂ，５ｂとの間に設けた凹所１７の深さは、図３に示すように、略円弧状の溝５，５，５の深さよりも大きな深さを有し、凹所１７の内面はリード線３０，３０，３０に接触しないようにし、かつ、上記挿入部材２０の外面の断面略円弧状の溝２５，２５，２５の上側の部分２５ａ，２５ａ，２５ａと下側の部分２５ｂ，２５ｂ，２５ｂとの間に設けた凹所２７の深さは、図３に示すように、略円弧状の溝２５，２５，２５の深さよりも大きな深さを有し、凹所２７の内面はリード線３０，３０，３０に接触しないようにしている。したがって、この凹所１７と２７とで、縁切り用の空隙３７が形成されて、もし仮に、水がリード線３０，３０，３０を伝わってきても、水をこの縁切り用の空隙３７で遮断して、水が内部に侵入するのを防止することができる。 2 and 3, between the upper portions 5a, 5a, 5a of the substantially arc-shaped grooves 5, 5, 5 on the inner surface of the housing 1 and the lower portions 5b, 5b, 5b. As shown in FIG. 3, the depth of the provided recess 17 has a depth larger than the depth of the substantially arc-shaped grooves 5, 5, 5, and the inner surface of the recess 17 has lead wires 30, 30, 30 and between the upper portions 25a, 25a, 25a and the lower portions 25b, 25b, 25b of the grooves 25, 25, 25 having a substantially arc-shaped cross section on the outer surface of the insertion member 20. As shown in FIG. 3, the depth of the provided recess 27 is greater than the depth of the substantially arc-shaped grooves 25, 25, 25, and the inner surface of the recess 27 has lead wires 30, 30, 30 is not touched.

The detailed description about is omitted, and different components will be described below.
　図７，９および１０において、リード線３０の延在方向、つまり、断面略円弧状の溝５，５，５と断面略円弧状の溝２５，２５，２５の延在方向について、ハウジング４０と挿入部材５０とは同じ長さを有する。 7, 9, and 10, the extension direction of the lead wire 30, that is, the extension direction of the grooves 5, 5, 5 having a substantially arc-shaped cross section and the grooves 25, 25, 25 having a substantially arc-shaped cross section, The insertion member 50 has the same length.
　図９および１０に示すように、上記ハウジング４０の下部の内面に断面略円弧状の溝５，５，５に夫々連なると共に、略円弧状の溝５，５，５よりも深い深さを有する個別凹所４７，４７，４７を形成し、かつ、挿入部材５０の下部の外面に断面略円弧状の溝２５，２５，２５に夫々連なると共に、略円弧状の溝２５，２５，２５よりも深い深さを有する個別凹所５７，５７，５７を形成している。これらの個別凹所４７，４７，４７と個別凹所５７，５７，５７とを対向させて、図８に示す個別凹部６８，６８，６８を形成して、リード線３０，３０，３０の回りに遮断用の空隙を形成している。 As shown in FIGS. 9 and 10, the inner surface of the lower portion of the housing 40 is continuous with the grooves 5, 5, 5 having a substantially arc-shaped cross section, and has a deeper depth than the grooves 5, 5, 5 having a substantially arc shape. The individual recesses 47, 47, 47 are formed, and the outer surface of the lower part of the insertion member 50 is continuous with the grooves 25, 25, 25 having a substantially arc-shaped cross section. Individual recesses 57, 57, 57 having a deep depth are formed. These individual recesses 47, 47, 47 and the individual recesses 57, 57, 57 are opposed to each other to form individual recesses 68, 68, 68 shown in FIG. 8 and around the lead wires 30, 30, 30. A gap for blocking is formed.
　これによって、ハウジング４０の外面に沿って滴下する水滴がリード線３０，３０，３０に伝わらなくて、水滴の内部への侵入を防止できる。 This prevents water droplets dripping along the outer surface of the housing 40 from being transmitted to the lead wires 30, 30, 30 and preventing the water droplets from entering the interior.
　なお、この第２実施形態のブッシングでは、第１実施形態のブッシングでは設けた下方に膨出した凸部１１を設けていないが、この下方に膨出した凸部１１を設ける方がより望ましいことは言うまでもない。 In the bushing of the second embodiment, the protruding portion 11 bulging downward provided in the bushing of the first embodiment is not provided, but it is more desirable to provide the protruding portion 11 protruding below. Needless to say.
　（第３実施形態）
　図１１はこの発明の第３実施形態のブッシングの要部である挿入部材６１，６２の正面図である。この第３実施形態のブッシングは挿入部材６１，６２の構成のみが第１実施形態のブッシングと異なる。したがって、図１１において、図４に示す第１実施形態の挿入部材２０の構成要素と同一構成については、図４に示す構成要素と同一参照番号を付して、それらの構成、作用についての説明は省略し、異なる構成要素について以下に説明する。なお、第１実施形態の図１に示すハウジング１を援用する。 (Third embodiment)
FIG. 11 is a front view of the insertion members 61 and 62 which are the main parts of the bushing according to the third embodiment of the present invention. The bushing of the third embodiment is different from the bushing of the first embodiment only in the configuration of the insertion members 61 and 62. Therefore, in FIG. 11, the same components as those of the insertion member 20 of the first embodiment shown in FIG. 4 are denoted by the same reference numerals as those of the components shown in FIG. Are omitted, and different components will be described below. In addition, the housing 1 shown in FIG. 1 of 1st Embodiment is used.
　この第３実施形態のブッシングは、図１１に示すように、２つの挿入部材６１，６２を含む。この挿入部材６１，６２は図１に示すハウジング１の貫通穴２に並べて挿入される。 The bushing of the third embodiment includes two insertion members 61 and 62 as shown in FIG. The insertion members 61 and 62 are inserted side by side in the through hole 2 of the housing 1 shown in FIG.
　このとき、挿入部材６１は２つの断面略円弧状の溝２５，２５を図１に示すリード線３０，３０に嵌合させつつ、貫通穴２に挿入し、挿入部材６２は１つの断面略円弧状の溝２５を図１に示すリード線３０に嵌合させつつ、貫通穴２に挿入する。 At this time, the insertion member 61 is inserted into the through hole 2 while fitting the grooves 25, 25 having two substantially arc-shaped cross sections into the lead wires 30, 30 shown in FIG. The arc-shaped groove 25 is inserted into the through hole 2 while being fitted to the lead wire 30 shown in FIG.
　このように、挿入部材６１，６２を複数個としているから、各挿入部材６１，６２とリード線３０，３０；３０との挿入時の摩擦抵抗が小さくなって、挿入部材６１，６２をハウジング１の貫通穴２に挿入し易くなる。 As described above, since a plurality of the insertion members 61 and 62 are provided, the frictional resistance at the time of insertion of each of the insertion members 61 and 62 and the lead wires 30, 30; It becomes easy to insert into the through hole 2.
　もし仮に、多くのリード線の全てを１つの挿入部材の外面とハウジングの貫通穴の内面とで保持しようとして、上記１つの挿入部材をハウジングの貫通穴に挿入しようとすると、上記挿入部材が多くのリード線の外面との摩擦抵抗によって貫通穴に挿入し難いことがあるのである。 If all the lead wires are held by the outer surface of one insertion member and the inner surface of the through hole of the housing, and the one insertion member is inserted into the through hole of the housing, the number of the insertion members is large. It may be difficult to insert into the through hole due to frictional resistance with the outer surface of the lead wire.
　（第４実施形態）
　図１２はこの発明の第４実施形態のブッシングの断面図である。 (Fourth embodiment)
FIG. 12 is a sectional view of a bushing according to a fourth embodiment of the present invention.

The lead wire 30 is tightly fitted and penetrated into the through hole 72 of the cylindrical body 70, and the lead wire 30 is provided at the lower end as at least one end of the cylindrical body 70 in the direction in which the lead wire 30 penetrates. The convex part 11 which continues in a ring shape and bulges downward is provided so as to surround.
　この下方に切れ目無く環状に連なった下方に膨出した凸部１１によって、筒体７０の外面に沿って滴下する水滴が、筒体７０の内面に入ること無く、下方に案内されて滴下することは、第１実施形態の下方に膨出した凸部１１の作用と同様である。この下方に膨出した凸部１１の詳しい作用は、第１実施形態の下方に膨出した凸部１１の説明と全く同一であるので、重複を避けるために、同一番号を付して説明を省略する。 By the convex part 11 bulging downward in a continuous ring shape below this continuous line, water drops dripping along the outer surface of the cylinder 70 are guided and dropped without entering the inner surface of the cylinder 70. Is the same as the operation of the convex portion 11 bulging downward in the first embodiment. The detailed operation of the convex portion 11 bulging downward is exactly the same as the description of the convex portion 11 bulging downward in the first embodiment. Omitted.
　また、上記筒体７０の下部の内周面とリード線３０との間に縁切り用の空隙７８を設けて、リード線３０の外面または筒体７０の下部の内周面に沿って、水滴が上昇しないようにしている。 In addition, a gap 78 is provided between the inner peripheral surface of the lower portion of the cylindrical body 70 and the lead wire 30 so that water droplets can flow along the outer surface of the lead wire 30 or the inner peripheral surface of the lower portion of the cylindrical body 70.

　なお、この第４実施形態では、下方に膨出した凸部１１を筒体７０の下端に設けたが、上端にも設けてもよい。 In addition, in this 4th Embodiment, although the convex part 11 bulged below was provided in the lower end of the cylinder 70, you may provide in the upper end.
　（第５実施形態）
　図１３はこの発明の第５実施形態のモータの断面図である。 (Fifth embodiment)
FIG. 13 is a sectional view of a motor according to a fifth embodiment of the present invention.
　この第５実施形態のモータは、モールド樹脂からなる本体８０と、積層鉄心からなる固定子８１と、この固定子８１に巻回したコイル８２と、軸８３と、この軸８３に固定した積層鉄心から回転子８５と、この回転子８５に埋設した磁石８６と、ブッシング１００とを備える。 The motor according to the fifth embodiment includes a main body 80 made of mold resin, a stator 81 made of a laminated iron core, a coil 82 wound around the stator 81, a shaft 83, and a laminated iron core fixed to the shaft 83. To a rotor 85, a magnet 86 embedded in the rotor 85, and a bushing 100.
　このブッシング１００は、第１～第４実施形態のいずれかに記載のブッシングである。上記固定子８１およびブッシング１００と、モールド樹脂からなる本体８０とは、モールド成形により一体化されており、上記ブッシング１００の一部１００ａは本体８０から下方に突出している。 This bushing 100 is the bushing according to any one of the first to fourth embodiments. The stator 81 and the bushing 100 and the main body 80 made of mold resin are integrated by molding, and a part 100 a of the bushing 100 protrudes downward from the main body 80.
　なお、９１，９２は上記軸８３を回転自在に支持する軸受、９３はブラケット、９５はリード線３０に電気接続される基板である。 Incidentally, 91 and 92 are bearings for rotatably supporting the shaft 83, 93 is a bracket, and 95 is a substrate electrically connected to the lead wire 30.
　上記構成のモータによれば、上述のブッシング１００を用いているので、ブッシング１００の一部１００ａが本体８０から下方に突出または露出していても、雨などの水がブッシング１００やリード線３０を伝ってモータ内に侵入することがない。 According to the motor having the above-described configuration, since the above-described bushing 100 is used, even if a part 100a of the bushing 100 protrudes or is exposed downward from the main body 80, water such as rain causes the bushing 100 and the lead wire 30 to pass through. It does not penetrate into the motor.
　上記ブッシング１００の外周囲に継ぎ目が無いハウジング１，４０または筒体７０（第１～第４実施形態を参照）と、樹脂からなる本体８０とがモールド成形されて一体化されているから、モータ内への水の侵入を防止でき、さらに、従来例のようなゴム製の防水部材を不要とすることが可能で、コストダウンをすることが可能である。 Since the housing 1, 40 or the cylindrical body 70 (see the first to fourth embodiments) without a joint around the outer periphery of the bushing 100 and the resin main body 80 are molded and integrated, the motor Water can be prevented from entering the inside, and a rubber waterproofing member as in the conventional example can be dispensed with, and the cost can be reduced.
　なお、上記第５実施形態では、ブッシング１００の一部１００ａが、モールド樹脂からなる本体８０から下方に突出していたが、側方に突出していてもよい。また、ブッシング１００はモールド樹脂からなる本体８０から突出していなくて、単に露出しているだけであってもよい。 In the fifth embodiment, the part 100a of the bushing 100 protrudes downward from the main body 80 made of mold resin, but may protrude laterally. Further, the bushing 100 does not protrude from the main body 80 made of the mold resin, and may simply be exposed.
　また、モータの本体はモールド樹脂に限らず、どのような材質であってもよい。 Further, the motor body is not limited to the mold resin, and any material may be used.
　第１～第５実施形態および変形例で述べた構成要素は、適宜、組み合わせてもよく、また、適宜、選択、置換、あるいは、削除してもよいのは、勿論である。 Of course, the components described in the first to fifth embodiments and modifications may be combined as appropriate, and may be selected, replaced, or deleted as appropriate.
