Description

本発明は新規な車輌用灯具の洗浄装置に関する。詳しくは、ピストンに支持された噴射ノズルが出し入れされる車体の開口部と該開口部に取り付けられるシリンダとの間にガタが生じないようにする技術分野に関する。   The present invention relates to a novel vehicle lamp cleaning apparatus. More specifically, the present invention relates to a technical field that prevents backlash from occurring between an opening of a vehicle body through which an injection nozzle supported by a piston is taken in and out and a cylinder attached to the opening.

車輌用灯具の洗浄装置、例えば、自動車用前照灯の前面カバー（レンズ）の汚れを洗浄するための洗浄装置が知られている。   2. Description of the Related Art A cleaning device for a vehicle lamp, for example, a cleaning device for cleaning dirt on a front cover (lens) of an automotive headlamp is known.

上記した車輌用灯具の洗浄装置は、シリンダによって駆動されるピストンの先端部に噴射ノズルを備え、ピストンがシリンダから突出された状態で、シリンダ及びピストンの内部を介して供給された洗浄液（水）が噴射ノズルから車輌用灯具に向かって噴射されるようになっている。   The above-described vehicle lamp cleaning device includes an injection nozzle at the tip of a piston driven by the cylinder, and the cleaning liquid (water) supplied through the cylinder and the piston in a state where the piston protrudes from the cylinder. Is sprayed from the spray nozzle toward the vehicle lamp.

そして、不使用時には、ピストンはシリンダ内に引込まれ、従って、噴射ノズルは車体の一部、例えば、バンパーに形成された開口部の内側の待機位置に位置されている。そして、使用時に、噴射ノズルが上記開口部から突出されて使用位置に出て行くことになる。従って、シリンダが開口部に対して位置決めされていないと、ピストンの移動に伴う噴射ノズルの移動軌跡が不安定となり、噴射ノズルやピストンが開口部の縁等に干渉してしまう惧れがある。そのために、シリンダを開口部に対して正確に位置決めすることが重要である。   When not in use, the piston is retracted into the cylinder, and therefore the injection nozzle is positioned at a standby position inside an opening formed in a part of the vehicle body, for example, a bumper. In use, the injection nozzle protrudes from the opening and goes out to the use position. Therefore, if the cylinder is not positioned with respect to the opening, the movement trajectory of the injection nozzle accompanying the movement of the piston becomes unstable, and the injection nozzle and the piston may interfere with the edge of the opening. Therefore, it is important to accurately position the cylinder with respect to the opening.

そこで、例えば、特許文献１に示された車輌用灯具の洗浄装置では、シリンダの前端部に取り付けたブラケット（３８）の係合位置決め部（４６）、（４６）の先端に形成された爪部（４６ｃ）、（４６ｃ）を開口部（３７）の互いに対向して位置した開口縁部の前面に係合させ、さらに、ブラケット（３８）の平らな板状をした片（４７）、（４７）の先端部を開口部の上記爪部（４６ｃ）、（４６ｃ）が係合する開口縁と略９０゜異なる向きで対向している開口縁に当接させて、ブラケット（３８）の前端部を開口部に位置決めし、且つ、ブラケット（３８）に形成された取付片（４１）、（４１）をボルト締めによって開口部（３７）から離れた位置で車体に固定している。なお、上記説明において、括弧内の数字は特許文献１の図面において各部に付された符号を示すものである。   Therefore, for example, in the vehicular lamp cleaning device disclosed in Patent Document 1, the engagement positioning portion (46) of the bracket (38) attached to the front end portion of the cylinder, the claw portion formed at the tip of (46) (46c) and (46c) are engaged with the front surface of the opening edge portion of the opening (37) facing each other, and the flat plate-like pieces (47) and (47) of the bracket (38) The front end of the bracket (38) is brought into contact with the opening edge facing the opening edge engaged with the claw portions (46c) and (46c) of the opening in a direction different by about 90 °. The mounting pieces (41) and (41) formed on the bracket (38) are fixed to the vehicle body at a position away from the opening (37) by bolting. In the above description, the numbers in parentheses indicate the symbols given to the respective parts in the drawing of Patent Document 1.

特許文献１の車輌用灯具の洗浄装置にあっては、上記したように、ブラケット（３８）の先端部が開口部（３７）に対して位置決めされ、これによって、間接的に、噴射ノズルの開口部（３７）に対する位置決めが為される。   In the vehicular lamp cleaning device of Patent Document 1, as described above, the tip of the bracket (38) is positioned with respect to the opening (37), thereby indirectly opening the injection nozzle. Positioning relative to the part (37) is performed.

特開２００３−１８２５３６号公報JP 2003-182536 A

ところで、上記した特許文献１に示された車輌用灯具の洗浄装置にあっては、ブラケット（３８）の前端部と開口部（３７）との係合は、前後方向に関しては、爪部（４６ｃ）、（４６ｃ）が開口縁の前面と係合しているのみであるので、取付片（４１）、（４１）が固定される位置と開口部（３７）の位置とが正確に位置決めされていないと、爪部（４６ｃ）、（４６ｃ）や係合位置決め部（４６）、（４６）に無理な力が加わったり、爪部（４６ｃ）、（４６ｃ）が開口部（３７）の開口縁部の前面から前方へ浮き上がって、位置決め状態が崩れると言った問題が生じる。また、係合位置決め部（４６）、（４６）が開口部（３７）の中心方向へと撓んで、爪部（４６ｃ）、（４６ｃ）の開口縁部との係合が外れてしまう惧れもある。   Incidentally, in the vehicular lamp cleaning device disclosed in Patent Document 1 described above, the engagement between the front end portion of the bracket (38) and the opening portion (37) is related to the claw portion (46c). ) And (46c) are only engaged with the front surface of the opening edge, the positions where the mounting pieces (41) and (41) are fixed and the position of the opening (37) are accurately positioned. Otherwise, excessive force is applied to the claw portions (46c), (46c) and the engagement positioning portions (46), (46), or the claw portions (46c), (46c) are the opening edges of the opening portion (37). The problem arises that the positioning state is lost due to floating upward from the front surface of the part. Further, the engagement positioning portions (46) and (46) may bend toward the center of the opening (37), and the engagement with the opening edges of the claw portions (46c) and (46c) may be disengaged. There is also.

そこで、本発明は、ピストンに支持された噴射ノズルが出し入れされる車体の開口部と該開口部に取り付けられるシリンダとの間にガタが生じないように、しかも、局部的に無理な力がかからないようにすることを課題とする。   Therefore, the present invention does not cause a backlash between the opening of the vehicle body through which the injection nozzle supported by the piston is put in and out and the cylinder attached to the opening, and does not apply excessive force locally. The challenge is to do so.

車輌用灯具の洗浄装置は、上記した課題を解決するために、シリンダに取り付けられ該シリンダを上記開口部に位置決めするブラケットと、上記ブラケットに外嵌状に位置される固定部材と、上記ブラケットと上記固定部材との間に位置される弾発部材とを備え、上記ブラケットは上記開口部の開口縁部の前側に係合する複数の係合片を有し、上記固定部材は上記開口部の開口縁部の後側に当接する複数の当接部を有し、上記ブラケットの複数の係合片と上記固定部材の複数の当接部とによってそれぞれ上記開口部の開口縁部を挟持し、且つ、上記固定部材を上記開口部側に付勢するように上記弾発部材が上記ブラケットと上記固定部材との間に介挿され、上記ブラケットには前方を向く平面状の受け面が形成され、上記固定部材の後端部に上記ブラケットの受け面に対してほぼ平行に対向する作用面を形成するとともに、該作用面の位置が上記噴射ノズルから遠くなるように固定部材が一定の長さ以上に形成され、上記ブラケットの受け面と上記固定部材の作用面との間に上記弾発部材としてバネが介挿されるようにしたものである。 In order to solve the above-described problem, a vehicular lamp cleaning device includes a bracket that is attached to a cylinder and positions the cylinder in the opening, a fixing member that is externally fitted to the bracket, and the bracket. A resilient member positioned between the fixing member and the bracket, the bracket having a plurality of engagement pieces that engage with the front side of the opening edge of the opening, and the fixing member of the opening A plurality of abutting portions that abut on the rear side of the opening edge, and sandwich the opening edge of the opening by the plurality of engaging pieces of the bracket and the plurality of abutting portions of the fixing member, Further, the resilient member is inserted between the bracket and the fixing member so as to bias the fixing member toward the opening, and a flat receiving surface facing forward is formed on the bracket. , At the rear end of the fixing member Forming a working surface that is substantially parallel to the receiving surface of the bracket, and a fixing member is formed to have a fixed length or more so that the position of the working surface is far from the injection nozzle. A spring is inserted as the elastic member between the surface and the working surface of the fixing member .

従って、本発明車輌用灯具の洗浄装置にあっては、車体の開口部と該開口部に取り付けられるシリンダ（シリンダに取り付けられたブラケット）との間にガタが生じることがなく、しかも、構成部材に局部的に無理な力がかかるようなことがない。   Therefore, in the vehicular lamp cleaning apparatus of the present invention, there is no backlash between the opening of the vehicle body and the cylinder (the bracket attached to the cylinder) attached to the opening, and the constituent members There is no such thing as applying excessive force locally.

本発明車輌用灯具の洗浄装置は、先端部に洗浄液を噴射する噴射ノズルと該噴射ノズルを前方に対して覆うノズルカバーを有するピストンと、上記ピストンを車体に設けられた開口部に対して出し入れするように駆動するシリンダとを備えた車輌用灯具の洗浄装置であって、上記シリンダに取り付けられ該シリンダを上記開口部に位置決めするブラケットと、上記ブラケットに外嵌状に位置される固定部材と、上記ブラケットと上記固定部材との間に位置される弾発部材とを備え、上記ブラケットは上記開口部の開口縁部の前側に係合する複数の係合片を有し、上記固定部材は上記開口部の開口縁部の後側に当接する複数の当接部を有し、上記ブラケットの複数の係合片と上記固定部材の複数の当接部とによってそれぞれ上記開口部の開口縁部を挟持し、且つ、上記固定部材を上記開口部側に付勢するように上記弾発部材が上記ブラケットと上記固定部材との間に介挿され、上記ブラケットには前方を向く平面状の受け面が形成され、上記固定部材の後端部に上記ブラケットの受け面に対してほぼ平行に対向する作用面を形成するとともに、該作用面の位置が上記噴射ノズルから遠くなるように固定部材が一定の長さ以上に形成され、上記ブラケットの受け面と上記固定部材の作用面との間に上記弾発部材としてバネが介挿されることを特徴とする。 The vehicle lamp cleaning device of the present invention includes a piston having an injection nozzle for injecting a cleaning liquid at the tip, a nozzle cover for covering the injection nozzle to the front, and the piston in and out of an opening provided in the vehicle body.

Are formed in the mounting portion 81 at intervals in the circumferential direction. And the attaching part 81 is externally fitted to the front end part of the cylinder 2, and the engaging projections 21a, 21a, ... of the cylinder 2 are engaged with the engaging holes 81a, 81a, ... of the attaching part 81, Thereby, the bracket 8 is fixed to the front end portion of the cylinder 2.

上記位置決め部８２の基部８２ａは前後方向に見てほぼ長四角の角筒状をしており、上記基部８２ａの短辺に沿った部分の前端からは２つの係合腕片８３、８４が前方へ向けて突出され、また、基部８２ａの長辺に沿った部分の前端の互いに離間した位置には位置決め片８５、８５、８６、８６が前方へ向けて突出されている。   The base portion 82a of the positioning portion 82 has a substantially long rectangular tube shape when viewed in the front-rear direction, and two engagement arm pieces 83, 84 are forward from the front end of the portion along the short side of the base portion 82a. Positioning pieces 85, 85, 86, 86 are projected forward at positions spaced apart from each other at the front end of the portion along the long side of the base portion 82a.

上記係合腕片８３の基部の両側部からは位置決め部８２の後端に向かって延びるスリット８３ａ、８３ａが形成され、これによって、係合腕片８３には板厚方向への弾性が付与されている。また、係合腕片８３の前端には外方、すなわち、他方の係合腕片８４と反対側に突出した係合片８３ｂが形成されている。さらに係合腕片８３の前端からやや後方の部分は外方へ突出した突出部８３ｃとされており、該突出部８３ｃの幅方向におけるほぼ中央に前後方向に延びるスリット８３ｄが形成されており、該スリット８３ｄの両側に係合縁８３ｅ、８３ｅが形成されている。   Slits 83a and 83a extending from the both sides of the base portion of the engagement arm piece 83 toward the rear end of the positioning portion 82 are formed, whereby the engagement arm piece 83 is given elasticity in the thickness direction. ing. In addition, an engagement piece 83 b is formed at the front end of the engagement arm piece 83 so as to protrude outward, that is, on the opposite side to the other engagement arm piece 84. Further, a portion slightly rearward from the front end of the engaging arm piece 83 is a protruding portion 83c that protrudes outward, and a slit 83d that extends in the front-rear direction is formed at substantially the center in the width direction of the protruding portion 83c. Engagement edges 83e and 83e are formed on both sides of the slit 83d.

上記他方の係合腕片８４の基部８２ａからの突出量は僅かであり、従って、該係合腕片８４には板厚方向へはほとんど撓むことがない剛性が付与されている。係合腕片８４の前端には外方、すなわち、上記一方の係合腕片８３と反対側に突出した係合片８４ａが形成されており、さらに、上記係合片８４ａより僅かに後方の位置から同じく外方へ突出した挟持片８４ｂが形成されている。なお、上記係合片８４ａと挟持片８４ｂとの間の間隔は車体１０に形成された開口部１１の開口縁部の板圧にほぼ等しく形成されている。   The amount of protrusion of the other engagement arm piece 84 from the base portion 82a is small, and thus the engagement arm piece 84 is given rigidity that hardly bends in the thickness direction. An engagement piece 84a is formed at the front end of the engagement arm piece 84 and protrudes outward, that is, on the opposite side of the one engagement arm piece 83, and is slightly behind the engagement piece 84a. A pinching piece 84b is also formed that protrudes outward from the position.

It is considered as a surface. Protruding portions 92, 93, 94, and 95 project from the four corners of the base 91 toward the front, and the front ends 92a, 93a, 94a, and 95a of the extending portions 92, 93, 94, and 95 are contact portions, respectively. ing. A bend restricting piece 96 as a bend restricting portion for restricting the bend of the engaging arm piece 83 of the bracket 8 is projected forward from a substantially intermediate position between the projecting portions 92 and 93. The deflection restricting piece 96 has a plate shape with a small width, and a protrusion 96a extending in the front-rear direction is formed at substantially the center in the width direction of the surface facing outward, and the rigidity of the bending restricting piece 96 is formed by the protrusion 96a. Has been increased.

１０１はクリップバネであり、側方から見てほぼＬ字状に屈曲された基端部１０１ａから間隔を置いて平行に位置した弾発片１０１ｂ、１０１ｂが突出されている。上記弾発片１０１ｂ、１０１ｂは長さ方向の中央が後方へ突出するように湾曲されている。   Reference numeral 101 denotes a clip spring, and projecting pieces 101b and 101b located parallel to each other are spaced from a base end portion 101a bent substantially in an L shape when viewed from the side. The bullet pieces 101b and 101b are curved so that the center in the length direction protrudes backward.

上記した車輌用灯具の洗浄装置１は車体１０の開口部１１に以下のようにして取り付けられる。   The above-described vehicle lamp cleaning device 1 is attached to the opening 11 of the vehicle body 10 as follows.

先ず、図２（ａ）に示すように、ブラケット８の弾性を有しない係合腕片８４の係合片８４ａと挟持片８４ｂとの間で開口部１１の長手方向の一端に位置する開口縁部を挟持した状態とする。なお、図２においてはブラケット８及び固定部材９の一部のみを示し、他の部分の図示は省略してある。   First, as shown in FIG. 2A, an opening edge located at one end in the longitudinal direction of the opening 11 between the engaging piece 84a and the holding piece 84b of the engaging arm piece 84 having no elasticity of the bracket 8 is provided. The part is sandwiched. In FIG. 2, only a part of the bracket 8 and the fixing member 9 is shown, and the other parts are not shown.

上記したように、図２（ｂ）に示すように、開口部１１の一の開口縁部を係合腕片８４の前端部で挟持した状態のまま、弾性を有する係合腕片８３を内側に、すなわち、他方の係合腕片８４の方へ撓ませた状態で係合片８３ｂを開口部１１の前側に通り抜けさせる。   As described above, as shown in FIG. 2B, the engaging arm piece 83 having elasticity is arranged on the inner side with one opening edge of the opening 11 held between the front ends of the engaging arm pieces 84. In other words, the engagement piece 83 b is passed through the front side of the opening 11 while being bent toward the other engagement arm piece 84.

図２（ｂ）に示すように、係合片８３ｂを開口部１１の前側に通り抜けさせた状態で、係合腕片８３を撓ませていた力を除くと、係合腕片８３が元の状態、すなわち、特別に力を加えられていない状態へと戻り、図２（ｃ）に示すように、係合片８３ｂが開口部１１の長手方向の他端に位置する開口縁部の前側に係合する。   As shown in FIG. 2 (b), when the engagement piece 83b is passed through the front side of the opening 11 and the force that has bent the engagement arm piece 83 is removed, the engagement arm piece 83 is restored to its original state. Returning to the state, that is, the state where no special force is applied, as shown in FIG. 2 (c), the engagement piece 83 b is on the front side of the opening edge located at the other end in the longitudinal direction of the opening 11. Engage.

図２（ｃ）に示すように、ブラケット８の前端部が開口部１１の開口縁部と係合した状態を後方から見た図が図３であり、前方から見た図が図４である。そして、ブラケット８の前端部が開口部１１の開口縁部と係合した状態で、ブラケット８の４つの位置決め片８５、８５、８６、８６は開口部１１の長手方向に沿う開口縁に当接した状態となり、これによって、ブラケット８は開口部１１に精確に位置決めされる。なお、本実施の形態において、係合腕片８３、８４の幅は、それぞれ開口部１１の長手方向における両端に位置する縁の長さにほぼ同じに形成され、且つ、４つの位置決め片８５、８５、８６、８６は開口部１１の長手方向に沿う開口縁に当接した状態となるため、これによって、ブラケット８の前端部の回転が規制される。   As shown in FIG. 2C, FIG. 3 shows a state in which the front end portion of the bracket 8 is engaged with the opening edge portion of the opening portion 11, and FIG. 4 shows a view seen from the front side. . The four positioning pieces 85, 85, 86, 86 of the bracket 8 are in contact with the opening edge along the longitudinal direction of the opening 11 with the front end of the bracket 8 engaged with the opening edge of the opening 11. As a result, the bracket 8 is accurately positioned in the opening 11. In the present embodiment, the widths of the engagement arm pieces 83 and 84 are formed substantially the same as the lengths of the edges located at both ends in the longitudinal direction of the opening 11, and the four positioning pieces 85 and 84 Since 85, 86, and 86 are in contact with the opening edge along the longitudinal direction of the opening portion 11, the rotation of the front end portion of the bracket 8 is restricted thereby.

図３及び図４に示すように、ブラケット８の前端部を開口部１１の開口縁部と係合させた状態で、固定部材９をシリンダ２の後方から外嵌して行く。このとき、シリンダ２の洗浄液供給管２２ａは固定部材９の基部９１の切欠９１ａを通過する。そして、固定部材９の前端、すなわち、４つの突っ張り部９２、９３、９４、９５の当接部９２ａ、９３ａ、９４ａ、９５ａが開口部１１の開口縁部の後面に当接し、その状態を図５に示す。   As shown in FIGS. 3 and 4, the fixing member 9 is externally fitted from the rear of the cylinder 2 with the front end of the bracket 8 engaged with the opening edge of the opening 11. At this time, the cleaning liquid supply pipe 22 a of the cylinder 2 passes through the notch 91 a of the base 91 of the fixing member 9. The front end of the fixing member 9, that is, the contact portions 92a, 93a, 94a, and 95a of the four protruding portions 92, 93, 94, and 95 are in contact with the rear surface of the opening edge portion of the opening portion 11, and the state thereof is illustrated. As shown in FIG.

固定部材９がシリンダ２に外嵌されてから図５に示す状態になるまでの間に、固定部材９の撓み規制片９６の先端がブラケット８の係合腕片８３の突出部８３ｃに形成された係合縁８３ｅ、８３ｅの内側、すなわち、突出部８３ｃの反突出側に対向し、また、撓み規制片９６に形成された突条９６ａが突出部８３ｃのスリット８３ｄの後端と対向した状態となり（図６参照）、図５に示すように、固定部材９の当接部９２ａ、９３ａ、９４ａ、９５ａが開口部１１の開口縁部の後面に当接した状態では、図７に示すように、撓み規制片９６が係合腕片８３の係合縁８３ｅ、８３ｅの内側に完全に入り込んだ状態となり、且つ、撓み規制片９６の突条９６ａが係合縁８３ｅと８３ｅとの間のスリット８３ｄ内に位置する。   The tip of the deflection regulating piece 96 of the fixing member 9 is formed on the protruding portion 83c of the engaging arm piece 83 of the bracket 8 after the fixing member 9 is fitted on the cylinder 2 until the state shown in FIG. The engagement edges 83e, 83e are opposed to the inner side of the projection 83c, that is, the opposite side of the projection 83c, and the protrusion 96a formed on the deflection regulating piece 96 is opposed to the rear end of the slit 83d of the projection 83c. 5 (see FIG. 6), as shown in FIG. 5, when the contact portions 92a, 93a, 94a, 95a of the fixing member 9 are in contact with the rear surface of the opening edge of the opening 11, as shown in FIG. In addition, the deflection regulating piece 96 is completely in the engagement edges 83e and 83e of the engagement arm piece 83, and the protrusion 96a of the deflection regulating piece 96 is between the engagement edges 83e and 83e. Located in the slit 83d.

図７に示すように、撓み規制片９６が係合腕片８３の係合縁８３ｅ、８３ｅの内側に完全に入り込んだ状態となると、図２（ｄ）に示すように、撓み規制片９６が係合腕片８３の内側に位置して、係合腕片８３の内側への倒れを阻止するので、係合腕片８３の係合片８３ｂの開口部１１の開口縁部の前面との係合が解除されることがない。   As shown in FIG. 7, when the deflection regulating piece 96 is completely in the engagement edges 83e and 83e of the engaging arm piece 83, the deflection regulating piece 96 is moved as shown in FIG. Since it is located inside the engagement arm piece 83 and prevents the engagement arm piece 83 from falling inward, the engagement arm piece 83 is engaged with the front surface of the opening edge of the opening 11 of the engagement piece 83b. The match will not be released.

図５に示すように、ブラケット８の係合片８３ｂ、８４ａと固定部材９の当接部９２ａ、９３ａ、９４ａ、９５ａとによって開口部１１の開口縁部を前後から挟持した状態を固定するために、クリップバネ１０１を、図５に矢印で示すように、ブラケット８の受け面８１ｃと固定部材９の作用面９１ｂとの間に介挿する。このとき、図８に示すように、ブラケット８の位置決め部８２の基部８２ａと受け面８１ｃとの間のネック部８１ｄをクリップバネ１０１の弾発片１０１ｂと１０１ｂとの間に位置させた状態とする。クリップバネ１０１を、図８に示したように、ブラケット８の受け面８１ｃと固定部材９の作用面９１ｂとの間に介挿すると、弾発片１０１ｂ、１０１ｂの湾曲状態が前後から押しつぶされた状態となり、それによって弾発片１０１ｂ、１０１ｂに生じる反力により、固定部材９が前方へ付勢され、その当接部９２ａ、９３ａ、９４ａ、９５ａとブラケット８の係合片８３ｂ、８４ａとで開口部１１の開口縁部を強固に挟持し、従って、シリンダ２が開口部１１において確実に車体１０に固定される。   As shown in FIG. 5, in order to fix the state in which the opening edge of the opening 11 is sandwiched from the front and rear by the engaging pieces 83b and 84a of the bracket 8 and the contact portions 92a, 93a, 94a and 95a of the fixing member 9. In addition, the clip spring 101 is interposed between the receiving surface 81 c of the bracket 8 and the action surface 91 b of the fixing member 9 as indicated by an arrow in FIG. 5. At this time, as shown in FIG. 8, a state in which the neck portion 81d between the base portion 82a of the positioning portion 82 of the bracket 8 and the receiving surface 81c is positioned between the elastic pieces 101b and 101b of the clip spring 101; To do. As shown in FIG. 8, when the clip spring 101 is inserted between the receiving surface 81c of the bracket 8 and the action surface 91b of the fixing member 9, the curved state of the elastic pieces 101b and 101b is crushed from the front and rear. The fixing member 9 is urged forward by the reaction force generated on the elastic pieces 101b and 101b, and the contact portions 92a, 93a, 94a and 95a and the engaging pieces 83b and 84a of the bracket 8 The opening edge of the opening 11 is firmly held, and therefore the cylinder 2 is securely fixed to the vehicle body 10 at the opening 11.

なお、ここでブラケット８の受け面８１ｃと固定部材９の作用面９１ｂとの間に介挿される弾発部材として、クリップバネ１０１を示したが、弾発部材がクリップバネ１０１に限ることを意味するものではない。しかしながら、弾発部材をクリップバネ１０１とすることにより、修理の必要等でシリンダ２を車体１０から取り外さなければならないときの、作業性が良好になる。また、クリップバネ１０１等の弾発部材の介挿位置であるが、開口部１１から比較的離間した位置とすることが好ましい。すなわち、シリンダ２等に外力が加わった場合、シリンダ２はブラケット８の前端部と開口部１１との係合箇所を中心に回動される力を受けるが、その場合、上記係合箇所から離れた位置に弾発部材がある方が、その弾発力が強く作用し、弾発部材が所定の位置から外れ難いからである。また、シリンダ２、ピストン３、チェックバルブ部４及びノズル体５、５を含む構造体のほぼ重心位置に弾発部材が位置していることがさらに好ましい。   Here, although the clip spring 101 is shown as a resilient member inserted between the receiving surface 81c of the bracket 8 and the action surface 91b of the fixing member 9, it means that the resilient member is limited to the clip spring 101. Not what you want. However, by using the clip spring 101 as the resilient member, workability is improved when the cylinder 2 must be removed from the vehicle body 10 due to the necessity of repair or the like. Moreover, although it is an insertion position of elastic members, such as the clip spring 101, it is preferable to set it as the position comparatively separated from the opening part 11. FIG. That is, when an external force is applied to the cylinder 2 or the like, the cylinder 2 receives a force that rotates around the engagement portion between the front end portion of the bracket 8 and the opening portion 11, but in that case, the cylinder 2 is separated from the engagement portion. This is because the elastic member acts more strongly when the elastic member is at the position, and the elastic member is less likely to be detached from the predetermined position. Further, it is more preferable that the resilient member is located at a substantially center of gravity position of the structure including the cylinder 2, the piston 3, the check valve portion 4, and the nozzle bodies 5, 5.

図９はクリップバネの変形例を示す図である。   FIG. 9 is a view showing a modification of the clip spring.

このクリップバネ１０２は、板バネ材料を側方から見てほぼ横倒Ｕ字状に曲げ、折曲部である基端部１０２ａの上下両端からそれぞれ互いにほぼ平行に延びる弾発片１０２ｂ、１０２ｂ及び１０２ｃ、１０２ｃが突出されて形成されている。このクリップバネ１０２は弾発片１０２ｂ、１０２ｃと１０２ｂ、１０２ｃとの間にブラケット８のネック部８１ｄが位置するように、ブラケット８の受け面８１ｃと固定部材９の作用面９１ｂとの間に介在され、弾発片１０２ｂ、１０２ｂが固定部材９の作用面９１ｂに弾接し、また、弾発片１０２ｃ、１０２ｃがブラケット８の受け面８１ｃに弾接した状態とされる。   The clip spring 102 is formed by bending a leaf spring material into a substantially U-shape when viewed from the side, and projecting pieces 102b, 102b extending substantially parallel to each other from upper and lower ends of a base end portion 102a which is a bent portion. 102c and 102c are formed to protrude. The clip spring 102 is interposed between the receiving surface 81c of the bracket 8 and the action surface 91b of the fixing member 9 so that the neck portion 81d of the bracket 8 is positioned between the elastic pieces 102b, 102c and 102b, 102c. Thus, the elastic pieces 102 b and 102 b are in elastic contact with the action surface 91 b of the fixing member 9, and the elastic pieces 102 c and 102 c are in elastic contact with the receiving surface 81 c of the bracket 8.

上記した車輌用灯具の洗浄装置１にあっては、ブラケット８に設けられた係合片８３ｂ、８４ａと固定部材９に設けられた当接部８２ａ、８３ａ、８４ａ、８５ａとによって開口部１１の開口縁部を前後から挟持することによってブラケット８の前端部が開口部１１に対して位置決めされ且つ固定されるので、一部の部材や部分に局部的に偏った負荷がかかることが無く、且つ、弾性を有する腕片８３の開口縁部との係合を脱する方向への撓みが規制されるため、ブラケット８の先端部が開口部１１から位置ずれを起こすことがない。   In the vehicle lamp cleaning device 1 described above, the opening 11 is formed by the engagement pieces 83b and 84a provided on the bracket 8 and the contact portions 82a, 83a, 84a and 85a provided on the fixing member 9. Since the front end portion of the bracket 8 is positioned and fixed with respect to the opening portion 11 by sandwiching the opening edge portion from the front and the back, a locally biased load is not applied to some members and portions, and Since the bending in the direction of releasing the engagement with the opening edge of the arm piece 83 having elasticity is restricted, the tip of the bracket 8 is not displaced from the opening 11.

また、ブラケット８の弾性を有する腕片８３を他方の腕片８４の方へと撓ませた状態で２つの腕片の係合片８３ｂ、８４ａを上記開口部１１の開口縁部前側に係合させた後に、固定部材９を後方からブラケット８に外嵌状に位置させて行って、撓み規制部である固定部材の撓み規制片９６が弾性を有する係合腕片８３の撓みを規制する位置に挿入されるので、ブラケット８の開口部１１への位置決め及び固定の作業を容易に行うことができる。   Further, the engagement pieces 83b and 84a of the two arm pieces are engaged with the front side of the opening edge of the opening 11 in a state where the arm piece 83 having elasticity of the bracket 8 is bent toward the other arm piece 84. Then, the fixing member 9 is positioned on the bracket 8 from the rear so as to be fitted externally, and the bending restricting piece 96 of the fixing member which is the bending restricting portion restricts the bending of the engaging arm piece 83 having elasticity. Therefore, the positioning and fixing work of the bracket 8 to the opening 11 can be easily performed.

さらに、他方の係合腕片８４は係合片８４ａが開口縁部と係脱する方向へはほとんど撓まない剛性を有すると共に、係合片８４ａと協同して開口部１１の開口縁部を前後から挟むために開口縁部の後側に当接する挟持片８４ｂを有するので、係合腕片８４の開口縁部への係合が安定し、かつ、ブラケット８の前端部が開口部１１の開口縁部から外れ難くなる。   Further, the other engagement arm piece 84 has rigidity that hardly bends in the direction in which the engagement piece 84a is engaged with or disengaged from the opening edge portion, and the opening edge portion of the opening portion 11 is formed in cooperation with the engagement piece 84a. Since the holding piece 84b is in contact with the rear side of the opening edge portion for holding from the front and rear, the engagement of the engagement arm piece 84 to the opening edge portion is stable, and the front end portion of the bracket 8 is the opening portion 11 of the opening portion 11. It becomes difficult to come off from the opening edge.

さらにまた、固定部材９の後端部はブラケット８に形成された平面状の受け面８１ｃに対してほぼ平行に対向する作用面９１ｂを有し、ブラケット８の受け面８１ｃと固定部材９の作用面９１ｂとの間に弾発部材であるリップバネ１０１又は１０２が介挿されるので、ブラケット８の前端部の開口部１１への係脱が容易であると共に、ブラケット８の前端部を開口部１１へ一旦係合すると、その係合状態が安定する。   Furthermore, the rear end portion of the fixing member 9 has an action surface 91b that faces the flat receiving surface 81c formed on the bracket 8 substantially in parallel, and the action of the receiving surface 81c of the bracket 8 and the fixing member 9 acts. Since the lip spring 101 or 102, which is a resilient member, is inserted between the surface 91b, the front end of the bracket 8 can be easily engaged with and disengaged from the opening 11, and the front end of the bracket 8 is temporarily connected to the opening 11. When engaged, the engaged state is stabilized.

なお、チェックバルブ部４の前端には噴射ノズル５、５を前方に対して覆うと共に、使用しないときに、開口部１１を前方から覆うためのノズルカバー７が支持される。そこで、該ノズルカバー７の上下にそれぞれ左右に離間したリブを形成しておき、ピストン３がシリンダ２内に引き込まれて、ノズルカバー７が開口部１１を覆うときに、ノズルカバー７に設けた上記リブがブラケット８の位置決め片８５、８５、８６、８６に当接するようにしておくことによって、ノズルカバー７を開口部１１に対して位置決めすることができる。   The front end of the check valve portion 4 covers the injection nozzles 5 and 5 with respect to the front, and a nozzle cover 7 for covering the opening 11 from the front when not in use. Therefore, ribs spaced apart from each other are formed on the upper and lower sides of the nozzle cover 7, and the piston 3 is provided in the nozzle cover 7 when the piston 3 is drawn into the cylinder 2 and the nozzle cover 7 covers the opening 11. The nozzle cover 7 can be positioned with respect to the opening 11 by making the rib contact the positioning pieces 85, 85, 86, 86 of the bracket 8.
