Description
本発明は、フィルタ及びその製造方法に関し、さらに詳しくは、フィルタ使用時のフィルタエレメントの抜けを抑制できると共に、濾過室内での溶着バリ等の異物の発生を抑制できるフィルタ及びその製造方法に関する。 The present invention relates to a filter and a method for manufacturing the same, and more particularly to a filter that can suppress the removal of a filter element when the filter is used and can suppress the generation of foreign matters such as welding burrs in a filtration chamber and the method for manufacturing the same.
従来より、自動変速機用のオイルフィルタとして、互いに突き合されて濾過室を形成する第1ケース部材及び第2ケース部材の各突合せ端部の間に、フィルタエレメントを挟持させてなるものが知られている(例えば、特許文献1及び2参照)。
上記特許文献1には、濾材3を、上部ケース1及び下部ケース2の各内側縁突起1d,2dによって圧縮緊締することが開示されている。しかし、この特許文献1では、濾材が圧縮緊締されているのみであるので、オイルフィルタの使用時に高い内圧がかかると濾材が抜けてしまう恐れがあった。
また、上記特許文献2には、下部カバー部材16に、濾過媒体20の縁部を貫通するスパイク56を設けてなるものが開示されている。しかし、この特許文献2では、スパイクで貫通された濾過媒体がやぶれて濾過不良を引き起こす恐れがあった。
Conventionally, as an oil filter for an automatic transmission, a filter element is sandwiched between each butted end portion of a first case member and a second case member that are butted against each other to form a filtration chamber. (For example, see Patent Documents 1 and 2).
Patent Document 1 discloses that the filter medium 3 is compression-tightened by the inner edge protrusions 1 d and 2 d of the upper case 1 and the lower case 2. However, in this patent document 1, since the filter medium is only compressed and tightened, there is a possibility that the filter medium may come off when a high internal pressure is applied when the oil filter is used.
Patent Document 2 discloses that the lower cover member 16 is provided with a spike 56 that penetrates the edge of the filtration medium 20. However, in this patent document 2, there is a possibility that the filtration medium penetrated by the spike may be broken and cause filtration failure.
そこで、上記問題を解決する従来の技術として、ケース部材とフィルタエレメントとをレーザ光により溶着させるものが提案されている(例えば、特許文献3参照)。
上記特許文献3には、レーザ吸収性を有するケース2の底面上に、レーザ透過性を有するフィルタ4を載せ、そのフィルタ4を冶具19で上下方向に加圧して溶着部位B2の繊維密度を高めると共に、冶具19のスリット19aを介してフィルタ4の縁部上面に向って加圧方向(上下方向)と同じ方向からレーザ光を照射して、ケース2とフィルタ4とを溶着させることが開示されている(特許文献3の図6及び図7等参照)。
Therefore, as a conventional technique for solving the above problem, a technique in which a case member and a filter element are welded with a laser beam has been proposed (for example, see Patent Document 3).
In Patent Document 3, a filter 4 having laser transmittance is placed on the bottom surface of the case 2 having laser absorption, and the filter 4 is pressed up and down by a jig 19 to increase the fiber density of the welded portion B2. In addition, it is disclosed that the case 2 and the filter 4 are welded by irradiating laser light from the same direction as the pressing direction (vertical direction) toward the upper surface of the edge of the filter 4 through the slit 19a of the jig 19. (See FIGS. 6 and 7 in Patent Document 3).
しかし、上記特許文献3では、フィルタエレメントの加圧方向からレーザ光を照射して、ケースの濾過室内に溶着部位B2を形成するようになっているので、レーザ光の出力等によっては、ケース内壁とフィルタエレメントの縁部との隙間や冶具のスリットで溶着バリ等の異物が発生し、その異物が濾過室内に残留して、フィルタとしての製品性能を悪化させる可能性があった。また、ケース内壁とフィルタエレメントの縁部との隙間での溶着バリ等の異物の発生を抑制するために、溶着部位をその隙間から十分に離れた位置に配設すると、ケースにおける溶着部位の外方側の寸法が大きくなり、フィルタ全体として大型化してしまうといった問題がある。
また、上記特許文献3では、押え冶具のスリットを介してレーザ光を照射しているので、溶着部位において必要十分な溶着幅を確保することが困難であった。また、必要十分な溶着幅を確保するために、押え冶具のスリット幅を大きな値に設定すると、押え冶具によるフィルタエレメントの加圧力が弱くなり溶着部位の繊維密度が低下して確実な溶着が困難なものとなる。
また、上記特許文献3では、レーザ光を、フィルタエレメントを透過させる必要がるので、レーザ透過性を有するフィルタエレメントを使用することが必須となっていた。
また、上記特許文献3では、フィルタエレメントの端縁部が濾過室内に露出しており、フィルタエレメントの端縁部の繊維等の欠落により製品性能を悪化させる可能性があるので、フィルタエレメントの厚み全体に溶融したレーザ吸収材を浸透させ固化させるといった微妙な調整が必要であり、透過率のバラツキ等も考慮したレーザ照射熱量の調整機能が必要となる。
さらに、フィルタエレメントとして、濾過面を大きくするためにひだ折り状のものを採用することがあるが、ひだ折り状部が複雑な3次元形状となっており、上記特許文献3では、フィルタエレメントの加圧方向からレーザ光を照射しているので、そのレーザ光を吸収側の溶融部材(ケース部材)に垂直に照射することができず、溶融部材を確実に溶融させることができなかった。さらに、ひだ折り状部に沿って溶着部にレーザ光の焦点距離を合わせるのが困難であるため、未溶着部と過溶着部(材料炭化部)が生じる恐れがある。
However, in Patent Document 3 described above, the laser beam is irradiated from the pressurizing direction of the filter element to form the welded portion B2 in the filtration chamber of the case. There is a possibility that foreign matters such as welding burrs are generated in the gap between the filter element and the edge of the filter element or the slit of the jig, and the foreign matters remain in the filtration chamber, thereby deteriorating the product performance as a filter. In addition, in order to suppress the generation of foreign matter such as welding burrs in the gap between the inner wall of the case and the edge of the filter element, if the welding part is disposed at a position sufficiently away from the gap, the outside of the welding part in the case There is a problem in that the dimension on the side increases and the size of the entire filter increases.
Moreover, in the said patent document 3, since the laser beam was irradiated through the slit of a holding jig, it was difficult to ensure the necessary and sufficient welding width in a welding site | part. In addition, if the slit width of the presser jig is set to a large value in order to secure the necessary and sufficient weld width, the pressurizing force of the filter element by the presser jig becomes weak and the fiber density at the welded part decreases, making sure welding difficult. It will be something.
Moreover, in the said patent document 3, since it is necessary to permeate | transmit a laser beam through a filter element, it was essential to use the filter element which has laser transmittance.
Moreover, in the said patent document 3, since the edge part of a filter element is exposed in the filtration chamber and there exists a possibility of deteriorating product performance by lack of the fiber etc. of the edge part of a filter element, the thickness of a filter element Subtle adjustments such as penetration and solidification of the melted laser absorber are necessary, and a function for adjusting the laser irradiation heat amount in consideration of variation in transmittance and the like is required.
Further, a fold-folded filter element may be used to increase the filtration surface. However, the fold-folded portion has a complicated three-dimensional shape. Since the laser beam is applied from the pressurizing direction, the laser beam cannot be irradiated perpendicularly to the absorption-side melting member (case member), and the melting member cannot be reliably melted. Further, since it is difficult to adjust the focal length of the laser beam along the fold-folded portion, there is a possibility that an unwelded portion and an overwelded portion (material carbonized portion) are generated.
以上より本発明は、上記現状に鑑みてなされたものであり、フィルタ使用時のフィルタエレメントの抜けを抑制できると共に、濾過室内での溶着バリ等の異物の発生を抑制できるフィルタ及びその製造方法を提供することを目的とする。 As described above, the present invention has been made in view of the above-described present situation, and it is possible to suppress a filter element from being removed when a filter is used, and to provide a filter and a method for manufacturing the same that can suppress the generation of foreign matters such as welding burrs in a filtration chamber. The purpose is to provide.

本発明のフィルタによると、第2ケース部材の突合せ端部とフィルタエレメントとの接触部の外側面側にはレーザ光によるエレメント用溶着部が形成されているので、このエレメント用溶着部によって第2ケース部材とフィルタエレメントとが強固に溶着される。従って、フィルタ使用時に濾過室内に過大な内圧がかかってもフィルタエレメントが第1及び第2ケース部材の間から抜けてしまうことを抑制できる。また、エレメント用溶着部が濾過室から十分に離れて配設されており、レーザ光の出力等によってエレメント用溶着部の付近で溶着バリ等の異物が発生しても、その異物が、第2ケース部材及びフィルタエレメントの当接面間を通って濾過室内に侵入することを抑制できる。
また、前記第1ケース部材が外壁部を有している場合は、この外壁部によって、少なくともフィルタエレメントの外側面を覆うことができ美観を向上させることができる。
また、前記外壁部と前記第2ケース部材の突合せ端部との当接部にはレーザ光によるケース用溶着部が形成されている場合は、上記エレメント用溶着部によって、第2ケース部材及びフィルタエレメントが溶着されると共に、ケース用溶着部によって、第1及び第2ケース部材が溶着される。従って、第1ケース部材、第2ケース部材及びフィルタエレメントの3部材を強固に一体化することができる。
また、前記外壁部が、前記第2ケース部材の突合せ端部の先端側外側面に所定間隔で対向している場合は、エレメント用溶着部で溶着バリが発生しても、その溶着バリは、第2ケース部材と外壁部との所定間隔の空間に排出され易く、溶着バリが濾過室内へ侵入することをより確実に抑制できる。
また、前記外壁部が、前記第2ケース部材の突合せ端部の先端側外側面に当接している場合は、エレメント用溶着部を形成する際に、外壁部によって溶融部の表面発熱部が冷却されることとなり、外壁部が当接しない場合と比べて、エレメント用溶着部の溶着深さ(突合せ方向と直交する方向の長さ)が大きな値となり、第2ケース部材及びフィルタエレメントの接合強度を向上させ得る。また、エレメント用溶着部が外壁部まで延びて形成されるので、エレメント用溶着部及びケース用溶着部によって、第1及び第2ケース部材がより強固に溶着される。
また、前記外壁部が、前記第2ケース部材の突合せ端部の先端側外側面に当接しており、前記エレメント用溶着部の他に溶着部が形成されていない場合は、エレメント用溶着部が外壁部側まで延びて形成され、このエレメント用溶着部によって、第2ケース部材及びフィルタエレメントが溶着されると共に、第1及び第2ケース部材が溶着される。従って、一度のレーザ照射によって3部材の一体化を図ることができ、レーザ照射時間を短縮できる。また、1つの溶着部のみを設けているので、より簡易且つ小型な構造とすることができる。
また、前記外壁部が、突合せ方向に沿って延びる当接面で前記第2ケース部材の突合せ端部に当接している場合は、第1及び第2ケース部材を突合せ方向に加圧する際に、加圧度合等によって第1及び第2ケース部材の突合せ方向に沿った相対的な移動距離が変わっても、外壁部と第2ケース部材の突合せ方向との当接面間の間隔が変わることはなく、第1及び第2ケース部材をより確実に溶着することができる。
また、前記第1ケース部材が嵌合部を有し、前記第2ケース部材が該嵌合部と突合せ方向に嵌合する被嵌合部を有している場合は、嵌合部及び被嵌合部の嵌め合いによって、ケース用溶着部を形成する際に、溶融部の熱膨張等による外壁部のそりを抑制できる。また、外壁部と第2ケース部材の突合せ端部との間に突合せ方向と直交する方向の初期隙間があっても、これを所定値以下に規制することができる。
また、前記嵌合部及び前記被嵌合部が、当接部に形成された溶着部の濾過室側に設けられている場合は、その溶着部付近で発生する溶着バリが濾過室内に侵入することを抑制できる。また、前記嵌合部及び前記被嵌合部が、当接部に形成された溶着部の反濾過室側に設けられている場合は、その溶着部付近で発生する溶着バリが外方に出ることを抑制できる。更に、前記嵌合部及び前記被嵌合部が、当接部に形成された溶着部の濾過室側及び反濾過室側の両側に設けられている場合は、第1ケース部材の曲がりをより確実に抑制できると共に、初期隙間をより確実に規制することができる。
また、ひだ折り状の前記フィルタエレメントを挟持し得るように、前記第1ケース部材及び前記第2ケース部材のそれぞれの突合せ端部には、くし歯状部が設けられている場合は、ひだ折り状のフィルタエレメントを第2ケース部材に直接的にレーザ溶着することができる。
According to the filter of the present invention, the element welding portion by the laser beam is formed on the outer surface side of the contact portion between the butted end portion of the second case member and the filter element. The case member and the filter element are firmly welded. Therefore, even if an excessive internal pressure is applied to the filtration chamber when the filter is used, it is possible to suppress the filter element from coming out between the first and second case members. Further, the element welding portion is disposed sufficiently away from the filtration chamber, and even if a foreign matter such as a welding burr is generated in the vicinity of the element welding portion due to the output of a laser beam or the like, the foreign matter is second Intrusion into the filtration chamber through the contact surfaces of the case member and the filter element can be suppressed.
Moreover, when the said 1st case member has an outer wall part, the outer surface of at least a filter element can be covered with this outer wall part, and aesthetics can be improved.
Further, in the case where a case welding portion by laser light is formed at the contact portion between the outer wall portion and the butting end portion of the second case member, the second case member and the filter are formed by the element welding portion. While the element is welded, the first and second case members are welded by the case welding portion. Therefore, the three members of the first case member, the second case member, and the filter element can be firmly integrated.
Further, when the outer wall portion faces the outer surface on the front end side of the butted end portion of the second case member at a predetermined interval, even if a welding burr occurs in the element welding portion, the welding burr is It is easy to be discharged into a space at a predetermined interval between the second case member and the outer wall portion, and it is possible to more reliably suppress the welding burr from entering the filtration chamber.
In addition, when the outer wall portion is in contact with the outer surface on the front end side of the butt end portion of the second case member, the surface heating portion of the melting portion is cooled by the outer wall portion when forming the weld portion for the element. Compared to the case where the outer wall portion does not come into contact, the welding depth of the element welded portion (the length in the direction orthogonal to the butting direction) becomes a large value, and the joint strength between the second case member and the filter element Can be improved. In addition, since the element weld portion extends to the outer wall portion, the first and second case members are more firmly welded by the element weld portion and the case weld portion.
Further, when the outer wall portion is in contact with the outer surface on the front end side of the butted end portion of the second case member and no welded portion is formed in addition to the welded portion for the element, the welded portion for the element is The second case member and the filter element are welded, and the first and second case members are welded together by the element welding portion. Therefore, the three members can be integrated by one laser irradiation, and the laser irradiation time can be shortened. Further, since only one welded portion is provided, a simpler and smaller structure can be achieved.
Further, when the outer wall portion is in contact with the butting end portion of the second case member with a contact surface extending along the butting direction, when pressurizing the first and second case members in the butting direction, Even if the relative movement distance along the abutting direction of the first and second case members changes depending on the degree of pressurization or the like, the distance between the contact surfaces of the outer wall portion and the abutting direction of the second case member does not change. In addition, the first and second case members can be more reliably welded.
In addition, when the first case member has a fitting portion and the second case member has a fitting portion that fits in the abutting direction with the fitting portion, the fitting portion and the fitting portion When the case weld portion is formed by fitting the joint portion, warpage of the outer wall portion due to thermal expansion of the melted portion or the like can be suppressed. Further, even if there is an initial gap in the direction orthogonal to the butting direction between the outer wall portion and the butting end portion of the second case member, this can be restricted to a predetermined value or less.
Further, when the fitting portion and the fitted portion are provided on the filtration chamber side of the welding portion formed in the contact portion, a welding burr generated near the welding portion enters the filtration chamber. This can be suppressed. Further, when the fitting portion and the fitted portion are provided on the side of the welding portion formed on the contact portion on the side opposite to the filtration chamber, a welding burr generated in the vicinity of the welding portion goes out. This can be suppressed. Further, when the fitting portion and the fitted portion are provided on both sides of the welded portion formed on the contact portion on the filtration chamber side and the anti-filtration chamber side, the first case member is further bent. While being able to suppress reliably, an initial clearance can be controlled more reliably.
In addition, when comb-shaped portions are provided at the butt ends of the first case member and the second case member so that the pleated filter element can be sandwiched, The filter element can be laser welded directly to the second case member.
本発明のフィルタの製造方法によると、第2ケース部材の突合せ端部にフィルタエレメントの縁部を接触させた状態で、該第2ケース部材の突合せ端部の先端側外側面及び前記フィルタエレメントの外側面に向って側方からレーザ光が照射される。その結果、第2ケース部材の突合せ端部とフィルタエレメントとの接触部の外側面側にはレーザ光によるエレメント用溶着部が形成され、このエレメント用溶着部によって、第2ケース部材とフィルタエレメントとが強固に溶着される。従って、フィルタ使用時に濾過室内に過大な内圧がかかってもフィルタエレメントが第1及び第2ケース部材の間から抜けてしまうことを抑制できる。また、エレメント用溶着部が濾過室から十分に離れて配置されており、レーザ光の出力等によってエレメント用溶着部の付近で溶着バリ等の異物が発生しても、その異物が、第2ケース部材及びフィルタエレメントの当接面間を通って濾過室内に侵入することを抑制できる。 According to the filter manufacturing method of the present invention, in the state where the edge of the filter element is brought into contact with the butted end of the second case member, the front end side outer surface of the butted end of the second case member and the filter element Laser light is irradiated from the side toward the outer surface. As a result, an element welded portion by laser light is formed on the outer surface side of the contact portion between the butted end of the second case member and the filter element, and the second case member and the filter element are formed by this element welded portion. Is firmly welded. Therefore, even if an excessive internal pressure is applied to the filtration chamber when the filter is used, it is possible to suppress the filter element from coming out between the first and second case members. In addition, the welded part for the element is arranged sufficiently away from the filtration chamber, and even if foreign matter such as weld burrs is generated near the welded part for the element due to the output of the laser beam, the foreign matter is not removed from the second case. Intrusion into the filtration chamber through the contact surfaces of the member and the filter element can be suppressed.

As long as the “filter element” (hereinafter also simply referred to as “element”) can be sandwiched between the respective butted ends of the first case member and the second case member, the shape, size, The material is not particularly limited. Examples of the shape of the element include a fold shape, a sheet shape, and a wave shape. Examples of the fold-shaped element include (1) a form composed of an element body having a large number of fold-shaped portions, and (2) an element body having a large number of fold-shaped portions, and a holding frame for holding the element body. The form etc. which consist of can be mentioned. Moreover, as a material of the said element, a nonwoven fabric, a textile fabric, paper etc. can be mentioned, for example. In addition, the said element may have a laser transmittance, for example, and may have a laser absorptivity.
In addition, it is preferable that the outer surface of the filter element does not protrude outward from the outer surface of the butted end portion of the second case member in a state where the filter element is sandwiched between the first and second case members.
上記第2ケース部材の突合せ端部と上記フィルタエレメントとの接触部の外側面側にはレーザ光によるエレメント用溶着部(W1)が形成されている(図3等参照)。 On the outer surface side of the contact portion between the butted end portion of the second case member and the filter element, an element welding portion (W1) by laser light is formed (see FIG. 3 and the like).
上記「エレメント用溶着部」の溶着幅、深さ、形状等は特に問わない。このエレメント用溶着部は、例えば、上記第2ケース部材の突合せ端部の先端側外側面及び前記フィルタエレメントの外側面に向って側方からレーザ光を照射することによって形成されることができる。このレーザ光の照射は、例えば、第1ケース部材及び第2ケース部材を突合せ方向に加圧した状態で行われることができる。
なお、レーザ光の照射は、通常、フィルタの外周に沿って連続して一様に行われ、上記エレメント用溶着部は、フィルタの外周に沿って連続して形成されることとなる。
The welding width, depth, shape, and the like of the “element welding portion” are not particularly limited. This element welding portion can be formed, for example, by irradiating laser light from the side toward the outer surface of the tip end side of the butted end portion of the second case member and the outer surface of the filter element. The laser beam irradiation can be performed, for example, in a state where the first case member and the second case member are pressurized in the butting direction.
Note that the laser beam irradiation is usually performed continuously and uniformly along the outer periphery of the filter, and the element weld is continuously formed along the outer periphery of the filter.
上記第1ケース部材は、例えば、突合せ方向に沿って延び且つ第2ケース部材の突合せ端部に当接する外壁部(124)を有していることができる(図5等参照)。 The first case member may have, for example, an outer wall portion (124) that extends along the butting direction and abuts against the butting end portion of the second case member (see FIG. 5 and the like).
上記「外壁部」の形状、大きさ等は特に問わない。この外壁部は、例えば、フィルタエレメントの外側面及び第2ケース部材の先端側外側面を覆うように設けられていることができる。また、上記外壁部は、例えば、任意の方向の当接面で第2ケース部材の突合せ端部に当接することができるが、第1及び第2ケース部材の加圧によって外壁部及び第2ケース部材の当接面間の隙間が変わらないといった観点から、上記外壁部が、突合せ方向に沿って延びる当接面で第2ケース部材の突合せ端部に当接していることが好ましい。
なお、上記「当接」とは、レーザ光による溶着部を形成できる程度の微小隙間(例えば、0.2mm以下の隙間)をもって対向することも含むものとする。
The shape and size of the “outer wall” are not particularly limited. This outer wall part can be provided so that the outer surface of a filter element and the front end side outer surface of a 2nd case member may be covered, for example. In addition, the outer wall portion can be brought into contact with the butted end portion of the second case member at an abutting surface in an arbitrary direction, for example. However, the outer wall portion and the second case are pressed by the pressure of the first and second case members. From the viewpoint that the gap between the contact surfaces of the members does not change, it is preferable that the outer wall portion is in contact with the butting end portion of the second case member with a contact surface extending along the butting direction.
In addition, the above “contact” includes facing with a minute gap (for example, a gap of 0.2 mm or less) that can form a welded portion by laser light.
上記外壁部と第2ケース部材の突合せ端部との当接部には、例えば、レーザ光によるケース用溶着部(W2)が形成されている(図5等参照)。この場合、上記ケース用溶着部及び上記エレメント用溶着部は、通常、少なくとも突合せ方向に位相がずらされている。 At the contact portion between the outer wall portion and the butting end portion of the second case member, for example, a case welding portion (W2) by laser light is formed (see FIG. 5 and the like). In this case, the case welding portion and the element welding portion are usually shifted in phase in at least the butting direction.
上記「ケース用溶着部」の溶着幅、深さ、形状等は特に問わない。このケース用溶着部は、例えば、外壁部と第2ケース部材の突合せ端部との当接部に向って第1ケース部材の外壁部の側方からレーザ光を照射することによって形成されることができる。このレーザ光の照射は、例えば、第1ケース部材及び第2ケース部材を突合せ方向に加圧した状態で行われることができる。
なお、レーザ光の照射は、通常、フィルタの外周に沿って連続して一様に行われ、上記ケース用溶着部は、フィルタの外周に沿って連続して形成されることとなる。
The welding width, depth, shape, etc. of the “case welding portion” are not particularly limited. The case welding portion is formed, for example, by irradiating laser light from the side of the outer wall portion of the first case member toward the contact portion between the outer wall portion and the butted end portion of the second case member. Can do. The laser beam irradiation can be performed, for example, in a state where the first case member and the second case member are pressurized in the butting direction.
In addition, the laser beam irradiation is normally performed continuously and uniformly along the outer periphery of the filter, and the case weld is continuously formed along the outer periphery of the filter.
ここで、上記外壁部の形成形態としては、例えば、(1)外壁部が、第2ケース部材の突合せ端部の先端側外側面に所定間隔で対向している形態(図5等参照)、(2)外壁部が、第2ケース部材の突合せ端部の先端側外側面に当接している形態(図13等参照)等を挙げることができる。 Here, as a form of formation of the outer wall part, for example, (1) a form in which the outer wall part faces the outer surface on the front end side of the butt end part of the second case member at a predetermined interval (see FIG. 5 and the like), (2) The form (refer FIG. 13 etc.) etc. which the outer wall part contact | abuts to the front end side outer surface of the butt | matching edge part of a 2nd case member can be mentioned.
上記(2)形態では、上記エレメント用溶着部は、外壁部側まで延びて形成されている。また、上記(2)形態では、エレメント用溶着部を形成する際に、外壁部によって溶融部(発熱部)が冷却されることとなり、上記(1)形態と比べて、エレメント用溶着部の溶着深さが大きな値となり、第2ケース部材及びフィルタエレメントの接合強度を向上させることができる。さらに、上記(2)形態の場合、第2ケース部材として低吸収性を有するものを採用することが好ましい。エレメント用溶着部の溶着深さをより長くでき、第2ケース部材とフィルタエレメントとの接合強度を更に向上させ得るためである。 In the above (2) mode, the element welding portion extends to the outer wall portion side. In the above (2) form, when forming the welded part for the element, the melted part (heat generating part) is cooled by the outer wall part, and the welded part for the element is welded compared to the above (1) form. The depth becomes a large value, and the bonding strength between the second case member and the filter element can be improved. Furthermore, in the case of the above (2) form, it is preferable to employ a material having low absorbency as the second case member. This is because the welding depth of the welded portion for the element can be made longer, and the bonding strength between the second case member and the filter element can be further improved.
なお、上記外壁部及び上記第2ケース部材の当接面の当接距離は、例えば、レーザ照射幅より大きな値(好ましくは、レーザ照射幅の2倍以上の値)に設定することができる。これにより、第1及び第2ケース部材の接合強度を向上させると共に、溶着バリの発生を抑制できる。これは、ケース用溶着部の溶着幅がレーザ照射幅より大きな値となるためである。 In addition, the contact distance between the contact surfaces of the outer wall portion and the second case member can be set to a value larger than the laser irradiation width (preferably, a value more than twice the laser irradiation width), for example. Thereby, while improving the joint strength of the 1st and 2nd case member, generation | occurrence | production of a welding burr | flash can be suppressed. This is because the welding width of the case welding portion is larger than the laser irradiation width.
上記ケース用溶着部が形成されない形態としては、例えば、上記外壁部が、第2ケース部材の突合せ端部の先端側外側面に当接しており、上記エレメント用溶着部(W)の他に溶着部が形成されていない形態(図19等参照)を挙げることができる。この場合、上記エレメント用溶着部は、外壁部側まで延びて形成されている。 As a form in which the weld portion for the case is not formed, for example, the outer wall portion is in contact with the outer surface on the front end side of the butt end portion of the second case member, and the weld portion other than the element weld portion (W) is welded. The form (refer FIG. 19 etc.) in which the part is not formed can be mentioned. In this case, the element welding portion extends to the outer wall side.
上記第1ケース部材は、例えば、嵌合部(122)を有し、上記第2ケース部材が嵌合部と突合せ方向に嵌合する被嵌合部(132)を有していることができる(図7等参照)。 The first case member may have, for example, a fitting portion (122), and a fitting portion (132) in which the second case member fits in the butting direction with the fitting portion. (See FIG. 7 etc.).
上記「嵌合部」及び「被嵌合部」の形状、大きさ、個数等は特に問わない。これらの配置形態としては、例えば、(1)嵌合部及び被嵌合部が、外壁部と第2ケース部材の突合せ端部との当接部に形成された溶着部の濾過室側にのみ設けられている形態(図6等参照)、(2)嵌合部及び被嵌合部が、上記溶着部の反濾過室側にのみ設けられている形態(図10等参照)、(3)嵌合部及び被嵌合部が、上記溶着部の濾過室側及び反濾過室側の両側に設けられている形態(図8等参照)等を挙げることができる。
なお、上記「当接部に形成された溶着部」とは、ケース用溶着部が形成される場合はケース用溶着部であり、ケース用溶着部が形成されない場合はエレメント用溶着部である。
The shape, size, number, etc., of the “fitting part” and “fitted part” are not particularly limited. As these arrangement | positioning forms, for example, (1) A fitting part and a to-be-fitted part are only in the filtration chamber side of the welding part formed in the contact part of an outer wall part and the butt | matching edge part of a 2nd case member. Form (see FIG. 6 etc.) provided, (2) Form (see FIG. 10 etc.) in which the fitting part and the fitted part are provided only on the anti-filtration chamber side of the weld part, (3) The form (refer FIG. 8 etc.) etc. which a fitting part and a to-be-fitted part are provided in the both sides by the side of the filtration chamber of the said welding part and an anti-filtration chamber can be mentioned.
The “welded portion formed at the contact portion” is a case weld portion when the case weld portion is formed, and an element weld portion when the case weld portion is not formed.
上記嵌合部及び被嵌合部は、例えば、突合せ方向と直交する方向に所定間隔(例えば、0.2mm以下)の隙間をもって嵌合されたり、圧入嵌合されたりすることができる。圧入嵌合される場合には、レーザ光を照射する前の嵌め合い状態で、上記外壁部及び第2ケース部材の当接部における各当接面間の間隔が0.2mm以上の隙間とならないようにすることが好ましい。なお、溶着条件等にもよるが、0.2mmより大きな間隔があると、両部材を良好に溶着できない恐れがある。
上記嵌合部及び被嵌合部は、例えば、突合せ方向に所定間隔の隙間をもって嵌合されることができる。これにより、加圧される第1及び第2ケース部材の突合せ方向の相対移動を吸収できる。
The fitting part and the fitted part can be fitted, for example, with a gap of a predetermined interval (for example, 0.2 mm or less) in a direction orthogonal to the butting direction, or press-fitted. When press-fitted, the gap between the contact surfaces of the outer wall portion and the contact portion of the second case member is not 0.2 mm or more in the fitted state before irradiating the laser beam. It is preferable to do so. Although depending on welding conditions and the like, if there is a gap larger than 0.2 mm, there is a possibility that both members cannot be welded well.
The fitting portion and the fitted portion can be fitted, for example, with a predetermined gap in the butting direction. Thereby, the relative movement of the pressed first and second case members in the butting direction can be absorbed.
なお、上記嵌合部及び被嵌合部を溶着部の近傍に設定する場合には、この嵌合部及び被嵌合部の嵌合幅(突合せ方向と直交する方向の幅)を2mm以上とすることが好ましい。これは、溶着部の第2ケース部材側への溶着深さが約1mm程度となるが、嵌合部及び被嵌合部の嵌合幅が2mm以上であると、嵌合部及び被嵌合部が熱変形し難く、また溶着バリの発生を抑制できるためである。 In addition, when setting the said fitting part and a to-be-fitted part in the vicinity of a welding part, the fitting width (width of the direction orthogonal to a butt | matching direction) of this fitting part and a to-be-fitted part shall be 2 mm or more. It is preferable to do. This means that the welding depth of the welded portion to the second case member side is about 1 mm. If the fitting width of the fitting portion and the fitting portion is 2 mm or more, the fitting portion and the fitting portion This is because the portion is not easily deformed by heat and the occurrence of welding burrs can be suppressed.
上記第1及び第2ケース部材の各突合せ端部には、例えば、くし歯状部(123,133)を設けることができる(図20等参照)。これにより、保持枠等を用いることなく、ひだ折り状のフィルタエレメントを直接的に第1及び第2ケース部材の間に挟持させることができる。 For example, comb-shaped portions (123, 133) can be provided at the abutting end portions of the first and second case members (see FIG. 20 and the like). Accordingly, the fold-fold filter element can be directly sandwiched between the first and second case members without using a holding frame or the like.
2.フィルタの製造方法
本実施形態に係るフィルタの製造方法は、上記実施形態1に係るフィルタの製造方法であって、互いに突き合されて濾過室を形成する第1ケース部材及び第2ケース部材のうちのレーザ吸収性を有する該第2ケース部材の突合せ端部にフィルタエレメントの縁部を接触させた状態で、該第2ケース部材の突合せ端部の先端側外側面及び前記フィルタエレメントの外側面に向って側方からレーザ光を照射することを特徴とする。これにより、上記第2ケース部材の突合せ端部と上記フィルタエレメントとの接触部の外側面側にレーザ光によるエレメント用溶着部が形成されることとなる。
2. Filter Manufacturing Method A filter manufacturing method according to the present embodiment is a filter manufacturing method according to the first embodiment, and includes a first case member and a second case member that are butted together to form a filtration chamber. With the edge of the filter element in contact with the butted end of the second case member having the above laser absorption property, the front end side outer surface of the butted end of the second case member and the outer surface of the filter element The laser beam is irradiated from the side. Thereby, the welding part for elements by a laser beam will be formed in the outer surface side of the contact part of the butting end part of the said 2nd case member, and the said filter element.
なお、上記フィルタエレメントがレーザ透過性を有している場合には、レーザ光の照射により第2ケース部材の突合せ端部の先端側外側面部が溶融して、その溶融部の一部がフィルタエレメントの内部へ浸透したり、その溶融部によってフィルタエレメントの一部が溶融したりし、溶融部の冷却後に上記エレメント用溶着部が形成されることとなる。また、上記フィルタエレメントがレーザ吸収性を有している場合には、レーザ光の照射により第2ケース部材の突合せ端部の先端側外側面部及びフィルタエレメントの外側面部が略同時に溶融し、溶融部が冷却されると上記エレメント用溶着部が形成されることとなる。 In the case where the filter element has laser transparency, the front side outer surface portion of the butt end portion of the second case member is melted by laser light irradiation, and a part of the melted portion is the filter element. Or a part of the filter element is melted by the melted portion, and the welded portion for the element is formed after the melted portion is cooled. When the filter element has laser absorptivity, the front side outer surface portion of the butt end portion of the second case member and the outer surface portion of the filter element are melted substantially simultaneously by the irradiation of the laser beam, When the element is cooled, the weld portion for the element is formed.
上記フィルタの製造方法は、例えば、第1ケース部材及び第2ケース部材のそれぞれの突合せ端部の間にフィルタエレメントの縁部を挟んだ状態で、該第1ケース部材及び該第2ケース部材を突合せ方向に加圧し、その加圧状態で、上記レーザ光を照射することができる。これにより、フィルタエレメントの加圧状態でレーザ光が照射されることとなり、フィルタエレメントの内部密度を高めてフィルタエレメント及び第2ケース部材の接合強度を向上させ得る。 The filter manufacturing method includes, for example, the first case member and the second case member in a state where the edge portion of the filter element is sandwiched between the butted ends of the first case member and the second case member. Pressurization is performed in the butt direction, and the laser beam can be irradiated in the pressurized state. As a result, the laser light is irradiated with the filter element in a pressurized state, so that the internal density of the filter element can be increased and the bonding strength between the filter element and the second case member can be improved.
上記フィルタの製造方法は、例えば、上記第1ケース部材に設けられた外壁部と、上記第2ケース部材の突合せ端部との当接部に向って第1ケース部材の外壁部の側方からレーザ光を照射する工程を更に備えることができる。これにより、外壁部と第2ケース部材の突合せ端部との当接部にはレーザ光によるケース用溶着部が形成されることとなる。
なお、レーザ光の照射により第2ケース部材の当接部が溶融して、その溶融部の熱が第1ケース部材の当接部に伝わって溶融し、第1及び第2ケース部材の両溶融部の冷却後に上記ケース用溶着部が形成されることとなる。また、上記ケース用溶着部を形成するレーザ光照射と、上記エレメント用溶着部を形成するレーザ光照射とは、所定の順番で行われてもよいし、同時に行われてもよい。
The method for manufacturing the filter is, for example, from the side of the outer wall portion of the first case member toward the contact portion between the outer wall portion provided on the first case member and the butted end portion of the second case member. A step of irradiating with laser light can be further provided. Thereby, the welding part for a case by a laser beam will be formed in the contact part of an outer wall part and the butt | matching edge part of a 2nd case member.
The contact portion of the second case member is melted by the laser light irradiation, and the heat of the melted portion is transferred to the contact portion of the first case member and melts, so that both the first and second case members are melted. The case welded portion is formed after the portion is cooled. Further, the laser beam irradiation for forming the case welded portion and the laser beam irradiation for forming the element welded portion may be performed in a predetermined order or simultaneously.
尚、本実施形態に係る他のフィルタの製造方法としては、例えば、上記実施形態1に係るフィルタの製造方法であって、互いに突き合されて濾過室を形成する第1ケース部材及び第2ケース部材のうちのレーザ吸収性を有する該第2ケース部材の突合せ端部にフィルタエレメントの縁部を接触させた状態であり、且つ、第1ケース部材に設けられた外壁部を第2ケース部材の突合せ端部の先端側外側面に当接させた状態で、該第2ケース部材の突合せ端部の先端側外側面及び前記フィルタエレメントの外側面に向って側方からレーザ光を照射することを特徴とする方法を挙げることができる。
これにより、第2ケース部材の突合せ端部と上記フィルタエレメントとの接触部の外側面側にレーザ光によるエレメント用溶着部が形成されることとなる。このエレメント用溶着部は外壁部側まで延びて形成されている。従って、上記エレメント用溶着部によって、第2ケース部材及びフィルタエレメントが溶着されると共に、第1及び第2ケース部材が溶着される。その結果、一度のレーザ照射によって3部材の一体化を図ることができ、レーザ照射時間を短縮できる。また、1つの溶着部のみを設けているので、より簡易且つ小型な構造とすることができる。
なお、上記フィルタの製造方法は、例えば、上述のように、第1及び第2ケース部材の加圧状態でレーザ光を照射することができる。
In addition, as another manufacturing method of the filter according to the present embodiment, for example, the manufacturing method of the filter according to the first embodiment, which is a first case member and a second case that are abutted with each other to form a filtration chamber. Of the members, the edge of the filter element is in contact with the butted end of the second case member having laser absorption, and the outer wall provided on the first case member is connected to the second case member. Irradiating laser light from the side toward the front end side outer surface of the butting end portion of the second case member and the outer side surface of the filter element in a state of being in contact with the front end side outer surface of the butting end portion. The characteristic method can be mentioned.
Thereby, the welding part for elements by a laser beam will be formed in the outer surface side of the contact part of the butting end part of the 2nd case member, and the said filter element. This element weld portion is formed to extend to the outer wall side. Therefore, the second case member and the filter element are welded and the first and second case members are welded by the element welding portion. As a result, the three members can be integrated by one laser irradiation, and the laser irradiation time can be shortened. Further, since only one welded portion is provided, a simpler and smaller structure can be achieved.
In addition, the manufacturing method of the said filter can irradiate a laser beam in the pressurization state of the 1st and 2nd case member as mentioned above, for example.
以下、図面を用いて実施例1〜8により本発明を具体的に説明する。なお、本実施例1〜8では、フィルタとして、車両の自動変速機用オイルフィルタを例示する。また、本実施例1〜8において、略同じ構成部位には同じ符号を付け詳説を省略するものとする。 Hereinafter, the present invention will be specifically described with reference to Examples 1 to 8 with reference to the drawings.

本実施例1に係るフィルタ1Aについて説明する。先ず、このフィルタ1Aの製造方法について説明すると、図2に示すように、上部ケース部材12の突合せ端部121と下部ケース部材13の突合せ端部131との間にエレメント14の縁部を挟んだ状態で、外力によって、各ケース部材12,13が突合せ方向Pに加圧される。このとき、エレメント14の縁部は低密度状態とされる。そして、その加圧状態で、エレメント14の外側面及び下部ケース部材13の突合せ端部131の先端側外側面に向って側方からレーザ光L1が照射される。

上記レーザ光L1は、外壁部124を透過して下部ケース部材13の突合せ端部131の先端側外側面部に至りその部位が溶融される。その溶融部の一部がエレメント14の構成繊維内に侵入したり、溶融部の発熱がエレメント14に伝達されエレメント14の構成繊維が部分的に溶融されたりする。さらに、その溶融部の発熱が上部ケース部材12の外壁部124に伝達されその部位が溶融され、レーザ光L1によるエレメント用溶着部W1が形成される。
一方、上記レーザ光L2は、外壁部124を透過して下部ケース部材13の突合せ端部131の基端側外側面部に至りその部位が溶融され、その溶融部の発熱が上部ケース部材12の外壁部124に伝達されその部位が溶融され、レーザ光L2によるケース用溶着部W2が形成される。なお、上記エレメント用溶着部W1及びケース用溶着部W2は、突合せ方向Pと直交する方向の位相が一致されている。

(実施例の効果)
本実施例1〜8のフィルタ1によると、下部ケース部材13の突合せ端部131とフィルタエレメント14との接触部の外側面側には、側方からのレーザ光L1の照射によるエレメント用溶着部W1が形成されているので、このエレメント用溶着部W1によって下部ケース部材13とフィルタエレメント14とが強固に溶着される。従って、フィルタ使用時に濾過室S内に過大な内圧がかかってもフィルタエレメント14が上部ケース部材12及び下部ケース部材13の間から抜けてしまうことを抑制できる。また、エレメント用溶着部W1が濾過室Sから十分に離れて配設されており、レーザ光L1の出力等によってエレメント用溶着部W1の付近で溶着バリ等の異物が発生しても、その異物が、下部ケース部材13及びフィルタエレメント14の当接面間を通って濾過室S内に侵入することを抑制できる。これにより、溶着後の濾過室S内の洗浄作業等を必要としない。
(Effect of Example)
According to the filters 1 of the first to eighth embodiments, the welded portion for the element by the irradiation of the laser beam L1 from the side is provided on the outer surface side of the contact portion between the
また、従来のように、突合せ方向からレーザ光を照射するものに比べて、エレメント溶着部W1より外方側のケース寸法を必要最小限に抑えることができ、簡易且つ小型な構造とすることができる。また、従来のようにレーザ光をフィルタエレメント中に透過させる必要がないので、レーザ透過性を有するフィルタエレメント14の採用を必須とせず、レーザ吸収性を有するフィルタエレメント14も採用できる。さらに、フィルタエレメント14の端縁部が濾過室S内に露出していないので、フィルタエレメント14の端縁部の繊維等が欠落することによって製品性能を悪化させることを防止できる。これにより、従来のように、フィルタエレメントの厚み全体に溶融したレーザ吸収材を浸透させ固化させるといった微妙な調整を必要とせず、透過率のバラツキ等も考慮したレーザ照射熱量の調整機能も必要としない。
In addition, as compared with the conventional case of irradiating laser light from the abutting direction, the case dimension on the outer side from the element welded portion W1 can be minimized, and a simple and compact structure can be obtained. it can. Further, since it is not necessary to transmit laser light into the filter element as in the prior art, it is not necessary to employ the
また、本実施例2〜8のフィルタ1では、上部ケース部材12に、突合せ方向Pに沿って延びる外壁部124を設けたので、この外壁部124によって、フィルタエレメント14、エレメント溶着部W1及びケース用溶着部W2の外側面を覆うことができ、製品の美観を向上させ得る。
また、本実施例2〜8のフィルタ1では、上部ケース部材12の外壁部124と下部ケース部材13の突合せ端部131との当接部にはレーザ光L2によるケース用溶着部W2が形成されているので、このケース用溶着部W2によって、上部ケース部材12及び下部ケース部材13が強固に溶着される。また、従来のように、押え冶具のスリットを介してレーザ光を照射するものに比べ、ケース用溶着部W2の溶着幅を十分大きな値に設定でき、各ケース部材12,13の接合強度を向上させ得る。

また、本実施例2〜8のフィルタ1では、上部ケース部材12の外壁部124を、突合せ方向Pに沿って延びる当接面で下部ケース部材13の突合せ端部131に当接させているので、各ケース部材12,13を突合せ方向Pに加圧する際に、加圧度合等によって各ケース部材12,13の突合せ方向Pに沿った相対的な移動距離が変わっても、外壁部124と下部ケース部材13の突合せ端部131の当接面間の間隔が変わることはなく、各ケース部材12,13をより確実に溶着することができる。
Further, in the filters 1 of Examples 2 to 8, the
また、本実施例2〜8のフィルタ1では、レーザ溶着によって、各ケース部材12,13及びフィルタエレメント14の3部材を一体化するようにしたので、従来のように、振動溶着等によって、合成樹脂製の保持枠で保持されたフィルタエレメント及び各ケース部材の3部材を振動溶着するものに比べて、生産工程を約半分に短縮させることができる。さらに、各ケース部材12,13の成形直後にレーザ溶着を実施できるので、各ケース部材12,13の成形からレーザ溶着完了までの自動化を図り、作業工数を短縮させることができる。
Further, in the filters 1 of Examples 2 to 8, since the three members of the
また、本実施例2〜5のフィルタ1では、上部ケース部材12の外壁部124を、下部ケース部材13の突合せ端部131の先端側外側面に所定間隔の空間をもって対向させているので、エレメント用溶着部W1で溶着バリが発生しても、その溶着バリは、所定間隔の空間に排出され易く、その溶着バリが濾過室S内へ侵入することをより確実に抑制できる。
Further, in the filters 1 of the second to fifth embodiments, the
また、本実施例6〜8のフィルタ1では、上部ケース部材12の外壁部124を、下部ケース部材13の突合せ端部131の先端側外側面に当接させているので、このエレメント用溶着部W1を形成する際に、外壁部124によって溶融部の外表面(発熱部)が冷却されることとなり、外壁部124が当接しないもの(実施例2〜5のフィルタ1)と比べて、エレメント用溶着部W1の溶着深さが大きな値となり、下部ケース部材13及びフィルタエレメント14の接合強度を向上させ得る。また、エレメント用溶着部W1が外壁部124側まで延びて形成されるので、エレメント用溶着部W1及びケース用溶着部W2によって、各ケース部材12,13がより強固に溶着される。
In the filters 1 of the sixth to eighth embodiments, the
また、本実施例3〜5、7及び8のフィルタ1では、上部ケース部材12及び下部ケース部材13に、突合せ方向Pに嵌合する嵌合部122及び被嵌合部132を設けたので、各嵌合部122及び被嵌合部132の嵌め合いによって、ケース用溶着部W2を形成する際に、その溶融部の熱膨張等による外壁部124のそりを抑制できる。また、上部ケース部材12の外壁部124と下部ケース部材13の突合せ端部131との間に、突合せ方向Pと直交する方向の初期隙間があっても、これを所定値(例えば、約0.2mm)以下に規制することができる。

また、本実施例3、4及び8のフィルタ1では、嵌合部122及び被嵌合部132を、ケース用溶着部W2の濾過室S側に設けたので、ケース用溶着部W2の付近で溶着バリ等の異物が発生しても、その異物が濾過室S内に侵入することを抑制できる。
また、本実施例4、5、7及び8のフィルタ1では、嵌合部122及び被嵌合部123を、ケース用溶着部W2の反濾過室S側に設けたので、ケース用溶着部W2の付近で溶着バリ等の異物が発生しても、その異物がケース外方に排出されることを抑制できる。
さらに、本実施例4及び8のフィルタ1では、嵌合部122及び被嵌合部123を、ケース用溶着部W2の濾過室S側及び反濾過室S側の両側に設けたので、上部ケース部材12の外壁部124のそりをより確実に抑制できると共に、外壁部124と下部ケース部材13との当接面間の初期隙間を所定値(例えば、約0.2mm)に規制することができる。

尚、本発明においては、上記実施例に限られず、目的、用途に応じて本発明の範囲内で種々変更した実施例とすることができる。即ち、上記実施例2〜8に係るフィルタ1では、レーザ光L1,L2によるエレメント用溶着部W1及びケース用溶着部W2を備えるようにしたが、これに限定されず、例えば、1つのエレメント用溶着部W1のみを備えるフィルタ1Iとしてもよい。
具体的には、図18に示すように、このフィルタ1Iでは、各ケース部材12,13の加圧状態で、外壁部124の内周面が、下部ケース部材13の突合せ端部131の先端側外側面に突合せ方向Pに沿って延びる当接面で当接している。また、上部ケース部材12の外壁部124に設けられた凸部122(本発明に係る「嵌合部」として例示する。)が、下部ケース部材13の突合せ端部131に設けられた凹部132(本発明に係る「嵌合部」として例示する。)に突合せ方向Pに沿って嵌合している。
そして、各ケース部材12,13の加圧状態で、エレメント14の外側面及び下部ケース部材13の突合せ端部131の先端側外側面に向って外壁部124の側方からレーザ光Lが照射される。すると、図19に示すように、下部ケース部材13の突合せ端部131とエレメント14との接触部の外側面側には、外壁部124側まで延びるエレメント用溶着部Wが形成される。
その結果、上記エレメント用溶着部Wによって、各ケース部材12,13及びフィルタエレメント14の3部材が溶着され、一度のレーザ照射によって3部材の一体化を図ることができ、レーザ照射時間を短縮できる。また、1つのエレメント溶着部Wのみを設けているので、より簡易且つ小型な構造とすることができる。
In the present invention, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. That is, in the filter 1 according to the second to eighth embodiments, the element welding portion W1 and the case welding portion W2 using the laser beams L1 and L2 are provided.

さらに、ひだ折り状のフィルタエレメント14’を備えるフィルタ1Jとすることもできる。具体的には、図20及び図21に示すように、このフィルタ1Jでは、各ケース部材12,13の突合せ端部121,131には、くし歯状部123,133が形成されている。そして、各ケース部材12,13の加圧状態において、各ケース部材12,13のくし歯状部123,133の間にフィルタエレメント14のひだ折り状部14aが挟持される。この状態で、各くし歯状部123,133及びフィルタエレメント14の外側面に向って側方からレーザ光を照射するとエレメント用溶着部が形成され、これら3部材12,13,14が溶着される。
このように、フィルタ1Jの側方からレーザ光を照射して、ひだ折り状のフィルタエレメント14’を下部ケース部材13に溶着するようにしたので、従来のように、各ケース部材12,13の加圧方向(突合せ方向P)からレーザ光を照射するものに比べ、そのレーザ光を吸収側の溶融部材(下部ケース部材13)に垂直に照射でき、溶融部材を確実に溶融させ得る。さらに、所定の照射幅を有するレーザ光を照射すれば、ひだ折り状部14aに沿って溶着部にレーザ光の焦点距離を合わせる必要がなく、より確実に溶着することができる。
なお、上記フィルタ1Jでは、各ケース部材12,13の突合せ端部121,131の内側領域に、フィルタエレメント14’のひだ折り状部14aを挟持するための複数の挟持用くし歯状部(図20において下部ケース部材13の挟持用くし歯状部134のみ図示する。)が設けられている。また、上記フィルタエレメント14’のシート状部14bは、上記実施例1〜8と同様にして、各ケース部材12,13の各突合せ端部121,131の間に挟持されるようになっている。
