Abstract

[Problem] To provide a fitting structure which is configured so that the easiness of mounting of a shaft body fitting part to a main shaft body is sufficiently improved. [Solution] This fitting structure is configured in such a manner that a front end sloped surface is formed at the front end of a main shaft body so as to obliquely intersect the axis of the main shaft body. This eliminates the need for aligning a fitting hole and the main shaft body with each other before starting fitting work, and the front-most end of the main shaft body can be easily passed through the fitting hole by only roughly matching the positions of the front-most end of the main shaft body and the fitting hole. Once the front-most end of the main shaft body has been inserted into the fitting hole, the edge of the front end sloped surface of the main shaft body does not butt against the edge of the fitting hole in the process of subsequent fitting work. As a result of this configuration, the work is not hindered, and the easiness of mounting of the shaft body fitting part to the main shaft body is sufficiently improved.

 本発明は、断面円形のメイン軸体と、そのメイン軸体が嵌合した嵌合孔を有する軸体嵌合部品との嵌合構造に関する。 The present invention relates to a fitting structure of a main shaft having a circular cross section and a shaft fitting component having a fitting hole into which the main shaft is fitted.
 従来、この種の嵌合構造を備えたものとして車両のドアを閉止状態にラッチするためのドアロック装置が知られている(例えば、特許文献1参照)。このドアロック装置は、軸体嵌合部品(特許文献1におけるロックレバー、サブロックレバー等)に貫通形成された嵌合孔の内側に、ドアロック装置のケースに突出形成されたメイン軸体(特許文献1における支軸102a,102c等)が挿入されて、軸体嵌合部品とメイン軸体とが殆どガタの無い状態で嵌合している。 Conventionally, a door lock device for latching a vehicle door in a closed state is known as having a fitting structure of this type (see, for example, Patent Document 1). This door lock device is a main shaft body (the main shaft body is formed projecting from the case of the door lock device inside a fitting hole formed through the shaft fitting part (lock lever, sub lock lever, etc. in Patent Document 1)). The spindles 102a and 102c and the like in Patent Document 1 are inserted, and the shaft fitting component and the main shaft are fitted in a state with almost no rattling.

 しかしながら、上述した従来の嵌合構造では、軸体嵌合部品の嵌合孔にメイン軸体を挿入する際に、嵌合孔の縁部にメイン軸体の先端外周縁が接触して、作業が頻繁に滞るという問題があった。これを防止するために、従来は、嵌合孔にメイン軸体を挿入する前に、それらを芯出ししておくという作業を強いられていた。 However, in the conventional fitting structure described above, when the main shaft is inserted into the fitting hole of the shaft fitting part, the outer periphery of the tip of the main shaft contacts the edge of the fitting hole, Often had a problem. In order to prevent this, conventionally, it has been forced to work to center them before inserting the main shaft into the fitting hole.

In the first resin cover 91, a groove main body 12A extending in the horizontal direction is formed in the back surface of the latch mechanism accommodation concave portion 91B, and in the portion facing the groove main body 12A of the sheet metal cover 93, the horizontal groove 12B. Is formed. The groove main body 12A and the horizontal groove 12B constitute a striker receiving groove 12, and one end of the striker receiving groove 12 is opened to the side projecting wall 91A to form a striker receiving opening 12K.
 図5に示すように、第1樹脂カバー91の内面には板金製の補強板94が重ねられ、その補強板94と板金カバー93との間が1対の金属製の回動支持ピン13J,14Jで連結されることで、板金カバー93と補強板94が第1樹脂カバー91に固定されている。また、図12に示すように、一方の回動支持ピン13Jは、ストライカ受容溝12より上方に配置され、他方の回動支持ピン14Jは、ストライカ受容溝12より下方に配置されている。そして、上側の回動支持ピン13Jにラッチ13が回動可能に支持される一方、下側の回動支持ピン14Jにラチェット14が回動可能に支持されている。 As shown in FIG. 5, a reinforcing plate 94 made of sheet metal is stacked on the inner surface of the first resin cover 91, and a pair of metal rotation support pins 13J, between the reinforcing plate 94 and the sheet metal cover 93, The sheet metal cover 93 and the reinforcing plate 94 are fixed to the first resin cover 91 by being connected by 14J. Further, as shown in FIG. 12, one rotation support pin 13J is disposed above the striker receiving groove 12, and the other rotation support pin 14J is disposed below the striker receiving groove 12. The latch 13 is rotatably supported by the upper rotation support pin 13J, and the ratchet 14 is rotatably supported by the lower rotation support pin 14J.
 図5に示すように、第1樹脂カバー91のうち補強板94が固定された内面側が、樹脂ボディ本体90の第1部品収容部90Aに収容され、第1部品収容部90Aの奥壁90Cに備えた貫通孔90D,96A(図4及び図7参照)を貫通した複数の螺子N1,N2を、第1樹脂カバー91に形成されたネジ下穴95D(図4参照)及び補強板94の螺子孔94N(図6参照)に締め付けることで、第1樹脂カバー91が樹脂ボディ本体90に固定されている。 As shown in FIG. 5, of the first resin cover 91, the inner surface side to which the reinforcing plate 94 is fixed is accommodated in the first component accommodation portion 90A of the resin body main body 90, and in the back wall 90C of the first component accommodation portion 90A. A plurality of screws N1 and N2 penetrating through the provided through holes 90D and 96A (see FIGS. 4 and 7), the screw lower hole 95D (see FIG. 4) formed in the first resin cover 91 and the screw of the reinforcing plate 94 The first resin cover 91 is fixed to the resin body main body 90 by tightening the holes 94N (see FIG. 6).
 ドアロック装置10は、板金カバー93をドア101の端部壁101Aの内面に宛う一方、第2樹脂カバー92をドア101の内装壁側に対向させた状態でドア101内部に配置される(図5参照)。そして、ドア101の端部壁101Aに備えた貫通孔に通したボルトを板金カバー93の螺子孔N3(図1A参照)に締め付けることでドアロック装置10がドア101に固定される。また、ドアロック装置10のストライカ受容溝12は、図1Bに示すように、ドア101に備えた切欠溝101Bに重ね合わされる。そして、車両100本体のドア枠100Wの内面に備えたストライカ15が、ドア101を閉めた際に、ストライカ受容口12Kからストライカ受容溝12内に進入する。 The door lock device 10 is disposed inside the door 101 in a state where the sheet metal cover 93 is disposed on the inner surface of the end wall 101A of the door 101 and the second resin cover 92 is opposed to the interior wall side of the door 101 See Figure 5). Then, the bolt passed through the through hole provided in the end wall 101 A of the door 101 is tightened to the screw hole N 3 (see FIG. 1A) of the sheet metal cover 93 to fix the door lock device 10 to the door 101. Further, as shown in FIG. 1B, the striker receiving groove 12 of the door lock device 10 is superimposed on the notch groove 101B provided in the door 101. Then, the striker 15 provided on the inner surface of the door frame 100W of the vehicle 100 main body enters the striker receiving groove 12 from the striker receiving port 12K when the door 101 is closed.
 図12に示すように、ラッチ13は、互いに平行になった第1と第2の係止爪13A,13Bを有し、それら第1と第2の係止爪13A,13Bの間がストライカ受容部13Cになっている。そして、ラッチ13のうち第1と第2の係止爪13A,13B同士を連絡する部分を前記した回動支持ピン13Jが貫通している。 As shown in FIG. 12, the latch 13 has first and second locking claws 13A and 13B parallel to each other, and a striker is received between the first and second locking claws 13A and 13B. It becomes part 13C. Then, a pivoting support pin 13J described above passes through a portion connecting the first and second locking claws 13A and 13B in the latch 13.
 また、ラッチ13は、樹脂製ボディ11との間に設けた図示しないトーションコイルバネによりアンラッチ方向(図12の時計回り方向)に付勢されている。そして、ドア101を開けた状態では、ラッチ13に備えたストッパ当接部13Dと樹脂製ボディ11に備えたストッパ11Xとの当接によりラッチ13がアンラッチ位置(図12に示した位置)に位置決めされる。 Further, the latch 13 is biased in the unlatching direction (clockwise direction in FIG. 12) by a torsion coil spring (not shown) provided between the latch 13 and the resin body 11. Then, when the door 101 is opened, the latch 13 is positioned at the unlatched position (the position shown in FIG. 12) by the abutment between the stopper abutting portion 13D provided in the latch 13 and the stopper 11X provided in the resin body 11. Be done.
 そのアンラッチ位置では、第1係止爪13Aがストライカ受容溝12の上方に退避しかつ、第2係止爪13Bがストライカ受容溝12を横切った状態になり、ストライカ受容部13Cの開口端がストライカ受容溝12のストライカ受容口12K側を向く。そして、ストライカ受容溝12に進入したストライカ15がストライカ受容部13C内に受容されると共に、ストライカ15が第2係止爪13Bを押してラッチ13がラッチ方向(図12における反時計回り方向)に回動する。これにより、図13に示すように、ストライカ受容溝12のうちストライカ15よりストライカ受容口12K側が第1係止爪13Aによって塞がれて、ラッチ13がストライカ15と噛み合った状態になる。 In the unlatched position, the first locking claw 13A retracts above the striker receiving groove 12 and the second locking claw 13B crosses the striker receiving groove 12 so that the open end of the striker receiving portion 13C is a striker. It faces the striker receiving port 12 K side of the receiving groove 12. Then, the striker 15 entering the striker receiving groove 12 is received in the striker receiving portion 13C, and the striker 15 pushes the second locking claw 13B to turn the latch 13 in the latch direction (counterclockwise direction in FIG. 12). Move. As a result, as shown in FIG. 13, the striker receiving port 12 K side of the striker receiving groove 12 from the striker receiving groove 12 is closed by the first locking claw 13 A, and the latch 13 is engaged with the striker 15.
 ラチェット14は、前述の如く回動支持ピン14Jによって回動可能に支持され、ラッチ回動規制片14Aとストッパ片14Bとを相反する方向に突出させて備えている。また、ラチェット14は、トーションコイルバネ14Sによって図12における反時計回り方向に付勢されている。これにより、ラチェット14は、通常は、ストッパ片14Bが樹脂製ボディ11に備えたラチェットストッパ11Dに当接した原点位置に位置決めされている。この原点位置で、ラチェット14のラッチ回動規制片14Aとラッチ13の第1係止爪13A及び第2係止爪13Bとが干渉し、ラチェット14が原点位置から時計回りに回動してリリース位置に至ると、ラチェット14のラッチ回動規制片14Aとラッチ13の第1係止爪13A及び第2係止爪13Bとが干渉しなくなる。なお、図4に示すように、トーションコイルバネ14Sのコイル部の内側を、後述する支軸97の基端部が貫通している。 As described above, the ratchet 14 is rotatably supported by the rotation support pin 14J, and has the latch rotation restriction piece 14A and the stopper piece 14B protruding in opposite directions. Further, the ratchet 14 is biased in the counterclockwise direction in FIG. 12 by the torsion coil spring 14S. Thus, the ratchet 14 is normally positioned at the home position where the stopper piece 14B is in contact with the ratchet stopper 11D provided on the resin body 11. At this home position, the latch rotation restricting piece 14A of the ratchet 14 interferes with the first locking claw 13A and the second locking claw 13B of the latch 13, and the ratchet 14 rotates clockwise from the home position and releases When it reaches the position, the latch rotation restricting piece 14A of the ratchet 14 and the first locking claw 13A and the second locking claw 13B of the latch 13 do not interfere with each other. In addition, as shown in FIG. 4, the base end part of the spindle 97 mentioned later has penetrated the inner side of the coil part of the torsion coil spring 14S.
 ドア101を開いた状態から閉じると、以下のようにしてラチェット14がラッチ13に係合する。即ち、ドア101が閉じられると、ストライカ15に押されて回動するラッチ13の第2係止爪13Bと第1係止爪13Aとが順次、ラチェット14のラッチ回動規制片14Aを押し下げて通過する。そして、ドア101がドア枠100Wとの間の防音部材101C(図1B参照)を最大限に押し潰した位置に至ると、ラッチ13は、ラチェット14のラッチ回動規制片14Aから第2係止爪13Bが僅かに離間したオーバーストローク位置に至り、これにより、ラチェット14は原点位置に戻る。そして、防音部材101Cの弾発力でドア101が押し戻されると、ラッチ13の第1係止爪13Aに対し、ストライカ受容部13Cの反対側からラチェット14のラッチ回動規制片14Aが突き当たり、ラッチ13がラッチ位置に位置決めされる。これにより、ラッチ13のラッチ解除方向への回動が規制されたラッチ状態になり、ドア101が全閉状態に保持される。 When the door 101 is closed from the open state, the ratchet 14 engages with the latch 13 as follows. That is, when the door 101 is closed, the second locking claw 13B and the first locking claw 13A of the latch 13 which are turned by being pushed by the striker 15 sequentially depress the latch rotation restriction piece 14A of the ratchet 14 pass. Then, when the door 101 reaches a position where the soundproof member 101C (see FIG. 1B) between the door frame 100W and the door frame 100W is maximally crushed, the latch 13 receives the second locking from the latch rotation restricting piece 14A of the ratchet 14. The claws 13B reach the slightly separated overstroke position, whereby the ratchet 14 returns to the home position. Then, when the door 101 is pushed back by the elastic force of the soundproof member 101C, the latch rotation restricting piece 14A of the ratchet 14 abuts against the first locking claw 13A of the latch 13 from the opposite side of the striker receiving portion 13C. 13 is positioned in the latch position. As a result, the rotation of the latch 13 in the latch releasing direction is restricted, and the door 101 is held in the fully closed state.
 ラチェット14によるラッチ13の回動規制は、図1Bに示すドア101の外装面に備えたアウトサイドドアハンドル104と、ドア101の内装面(車内面)に備えた図示しないインサイドドアハンドルとの何れかの操作によって解除することができる。それらアウトサイドドアハンドル104及びインサイドドアハンドルからの操作力をラチェット14に伝達するために、図14Aに示したリフトレバー16が、ラチェット14に一体的に回動するように取り付けられている。 The rotation restriction of the latch 13 by the ratchet 14 is either the outside door handle 104 provided on the exterior surface of the door 101 shown in FIG. 1B or the inside door handle (not shown) provided on the interior surface (inner surface) of the door 101. It can be released by the operation of The lift lever 16 shown in FIG. 14A is attached to the ratchet 14 so as to rotate integrally with the ratchet 14 in order to transmit the operation force from the outside door handle 104 and the inside door handle to the ratchet 14.
 具体的には、リフトレバー16は、図6に示すように、回動支持ピン14Jのうち第1樹脂カバー91と補強板94とに挟まれた部分に回動可能に軸支されている。また、図14Aに示すように、リフトレバー16には、回動支持ピン14Jからストライカ受容溝12(図12参照)のストライカ受容口12K側(以下、これを「前側」といい、その反対側を「後側」という)に向かって突出した第1傾動アーム16Aと、回動支持ピン14Jから後側の斜め下方に向かって突出した第2傾動アーム16Cとが備えられている。そして、第2傾動アーム16Cの上縁部から直角曲げされた係合突片16Kがラチェット14に備えた係合孔14C(図12参照)に凹凸係合して、リフトレバー16がラチェット14と一体的に回動する。また、第1傾動アーム16Aには、その前端部を直角に折り曲げてなる先端当接部16Bが設けられると共に、第2傾動アーム16Cには、その後端部を直角に折り曲げかつ、第2傾動アーム16Cより前側斜め下方に突出させた突当突片16Dが備えられている。 Specifically, as shown in FIG. 6, the lift lever 16 is pivotally supported by a portion of the pivot support pin 14J which is sandwiched between the first resin cover 91 and the reinforcing plate 94. Further, as shown in FIG. 14A, in the lift lever 16, the striker receiving port 12K side (hereinafter referred to as “front side”) of the striker receiving groove 12 (see FIG. 12) from the pivoting support pin 14J Is referred to as “rear side”), and a second tilting arm 16C which protrudes rearward and obliquely downward from the rotation support pin 14J. Then, the engagement projection 16K bent at a right angle from the upper edge of the second tilting arm 16C engages with the engagement hole 14C (see FIG. 12) provided on the ratchet 14 in a concavo-convex manner, and the lift lever 16 engages with the ratchet 14 Integrally rotate. The first tilting arm 16A is provided with a tip contact portion 16B formed by bending its front end at a right angle, and the second tilting arm 16C is bent a rear end at a right angle and a second tilting arm An abutting projection 16D is provided which is projected obliquely downward on the front side of 16C.
 図14Aに示すように、回動支持ピン14Jより後側の斜め下方位置には、後述する支軸97が配置され、その支軸97を構成する支持突部95の外側にアウトサイドオープンレバー17が回動可能に支持されている。アウトサイドオープンレバー17は、本発明の「軸体嵌合部品」及び「回動レバー」に相当し、支持突部95から前側に突出した支持アーム17Aと、支持突部95から後側に突出した操作アーム17Dとを備えている。そして、アウトサイドオープンレバー17は、樹脂ボディ本体90に一体形成されたストッパ部90S(図7及び図8参照)に操作アーム17Dの上縁部が当接することで回動範囲を規制され、図14A及び図14Bに示された原点位置と、その原点位置より所定角だけ同図の時計回り方向に回動した作動位置(図15A及び図15B参照)との間を回動する。また、アウトサイドオープンレバー17が原点位置に配置されると、支持アーム17Aは前下がりに傾斜した姿勢になり(図14A参照)、アウトサイドオープンレバー17が作動位置になると支持アーム17Aが水平姿勢に近づき、わずかに前下がりに傾斜した姿勢になる(図15A参照)。 As shown in FIG. 14A, a support shaft 97 described later is disposed at an obliquely lower position on the rear side of the rotation support pin 14J, and the outside open lever 17 is provided outside the support projection 95 that constitutes the support shaft 97. Is rotatably supported. The outside open lever 17 corresponds to the “shaft fitting part” and the “pivotal lever” of the present invention, and protrudes to the rear side from the support arm 17A that protrudes to the front side from the support projection 95 and the support projection 95 And a control arm 17D. The outside open lever 17 is restricted in its rotation range as the upper edge of the operating arm 17D abuts against a stopper 90S (see FIGS. 7 and 8) integrally formed on the resin body 90. It pivots between the home position shown in FIG. 14A and FIG. 14B and the operating position (see FIGS. 15A and 15B) rotated clockwise by a predetermined angle from the home position. In addition, when the outside open lever 17 is disposed at the origin position, the support arm 17A is inclined downward to the front (see FIG. 14A), and when the outside open lever 17 is in the operation position, the support arm 17A is horizontally oriented. And slightly inclined forward and downward (see FIG. 15A).
 さらに、アウトサイドオープンレバー17は、支持突部95(支軸97)の外側に遊嵌されたトーションコイルバネ18(図4、図6及び図14A参照)によって、原点位置側に付勢されている。詳細には、アウトサイドオープンレバー17は、支軸97と平行な方向に直角曲げされた係止突部17Xを備えており、トーションコイルバネ18のコイル部18Cから側方に突出した一方のバネ端末部がその係止突部17Xに係止され、他方のバネ端末部が前記ストッパ部90Sの上面に係止されている(図7参照)。なお、トーションコイルバネ18は、本発明の「軸体嵌合部品」に相当する。 Furthermore, the outside open lever 17 is biased toward the origin by the torsion coil spring 18 (see FIGS. 4, 6 and 14A) loosely fitted to the outside of the support projection 95 (support shaft 97). . Specifically, the outside open lever 17 has a locking projection 17X bent at a right angle in a direction parallel to the support shaft 97, and one spring end projecting laterally from the coil portion 18C of the torsion coil spring 18 The portion is locked to the locking projection 17X, and the other spring end portion is locked to the upper surface of the stopper portion 90S (see FIG. 7). The torsion coil spring 18 corresponds to the “shaft fitting part” in the present invention.
 支持アーム17Aの前端部には、係合孔17Bが支軸97の軸方向と平行な方向に貫通形成されている。その係合孔17Bは、その内周面における180度離れた2位置から互いに接近する側に1対の山形突部17T,17Tを突出させた形状になっている。 At the front end portion of the support arm 17A, an engagement hole 17B is penetratingly formed in a direction parallel to the axial direction of the support shaft 97. The engagement hole 17B has a shape in which a pair of chevrons 17T and 17T project toward the side approaching each other from two positions 180 degrees apart on the inner circumferential surface.

Further, one end of a rod (not shown) is connected to the inside of the resin ring 17V, and the other end of the rod is connected to the outside door handle 104. Then, when the outside door handle 104 is operated, the engaging portion 17E is pushed downward, and the outside open lever 17 rotates from the home position to the operating position.
 図14Aに示すように、アウトサイドオープンレバー17の係合孔17Bには、オープンリンク19の係合突片19Aが回動可能に係合している。オープンリンク19は、全体が上下方向に延びた形状をなし、下端部から支軸97の軸方向に上記した係合突片19Aが突出している。そして、オープンリンク19は、係合孔17Bにおける前記した1対の山形突部17T,17Tによって回動範囲が規制され、前側に倒れたアンロック位置と、後側に倒れたロック位置との間を回動する。また、オープンリンク19とアウトサイドオープンレバー17との間には、トーションコイルバネ29(図14B,図15A及び図15Bでは省略)が設けられ、このトーションコイルバネ29によってオープンリンク19は、アンロック位置側に付勢されている。 As shown in FIG. 14A, the engagement protrusion 19A of the open link 19 is rotatably engaged with the engagement hole 17B of the outside open lever 17. The open link 19 has a shape extending in the vertical direction as a whole, and the engagement protrusion 19A described above protrudes in the axial direction of the support shaft 97 from the lower end. The open link 19 is restricted in its rotation range by the pair of chevrons 17T and 17T in the engagement hole 17B, and it is between the unlock position which has fallen to the front and the lock position which has fallen to the rear. Rotate. In addition, a torsion coil spring 29 (not shown in FIGS. 14B, 15A and 15B) is provided between the open link 19 and the outside open lever 17, and the open link 19 is unlocked by the torsion coil spring 29. It is biased by
 オープンリンク19の上縁部からは、押上突片19Cが支軸97の軸方向に折り曲げて突出している。そして、オープンリンク19がアンロック位置に配置されると、図14Bに示すように、押上突片19Cがリフトレバー16における先端当接部16Bの下方に位置し、この状態でアウトサイドオープンレバー17が原点位置から作動位置に回動すると、図15Bに示すように、押上突片19Cがリフトレバー16の先端当接部16Bを押し上げる。これにより、リフトレバー16がラチェット14(図13参照)と共に原点位置からリリース位置へと回動し、ラチェット14とラッチ13との係合が解除されて、ドア101が開かれる。 From the upper edge of the open link 19, a push-up projection 19 C is bent in the axial direction of the support shaft 97 and protrudes. When the open link 19 is disposed at the unlock position, as shown in FIG. 14B, the push-up projection 19C is positioned below the tip contact portion 16B of the lift lever 16, and in this state the outside open lever 17 When the lever pivots from the home position to the actuation position, as shown in FIG. 15B, the push-up projection 19C pushes up the tip contact portion 16B of the lift lever 16. As a result, the lift lever 16 pivots from the home position to the release position together with the ratchet 14 (see FIG. 13), the engagement between the ratchet 14 and the latch 13 is released, and the door 101 is opened.
 一方、オープンリンク19がロック位置に配置されると、図14Aに示すように、押上突片19Cはリフトレバー16における先端当接部16Bより回動支持ピン14J側にずれる。よって、この状態でアウトサイドオープンレバー17が原点位置から作動位置に回動しても、図15Aに示すように、押上突片19Cがリフトレバー16の先端当接部16Bを押し上げることがなくなる。即ち、オープンリンク19がロック位置に配置されたときには、アウトサイドドアハンドル104を操作してもドア101を開くことができないロック状態になる。 On the other hand, when the open link 19 is disposed at the lock position, as shown in FIG. 14A, the push-up protrusion 19C is displaced to the rotation support pin 14J side from the tip contact portion 16B of the lift lever 16. Therefore, even if the outside open lever 17 pivots from the home position to the working position in this state, the lifting projection 19C does not push up the tip contact portion 16B of the lift lever 16 as shown in FIG. 15A. That is, when the open link 19 is disposed in the lock position, the door 101 can not be opened even if the outside door handle 104 is operated.
 オープンリンク19の下端寄り位置からは下端アーム19Fが前方に突出していて、その下端アーム19Fの下縁部から、ロック解除片19Bが支軸97の軸方向に折り曲げられかつ前方に突出している。そして、このロック解除片19Bを、後述するアクティブレバー25が上方に押し上げることで、オープンリンク19がアンロック位置からロック位置に切り替えられる。 A lower end arm 19F protrudes forward from a lower end position of the open link 19, and an unlocking piece 19B is bent in the axial direction of the support shaft 97 and protrudes forward from the lower edge portion of the lower end arm 19F. Then, the open link 19 is switched from the unlock position to the lock position by pushing the lock release piece 19B upward by an active lever 25 described later.
 上記した樹脂ボディ本体90の第2部品収容部90Bには、図16に示したインサイドオープンレバー20、アクティブレバー25、連結バー30、中継レバー31等が収容されている。なお、以下、各部品の説明において、第2樹脂カバー92と対向する面(図16の紙面の表側を向いた面)をその部品の「外面」ということとし、その反対側の面をその部品の「内面」ということとする。 The inside open lever 20, the active lever 25, the connecting bar 30, the relay lever 31 and the like shown in FIG. 16 are housed in the second component housing portion 90B of the resin body main body 90 described above. Hereinafter, in the description of each part, the surface facing the second resin cover 92 (the surface facing the front side of the sheet of FIG. 16) is referred to as the "outside" of the part, and the opposite side is the part "Inside" of the.
 インサイドオープンレバー20は、第2部品収容部90Bのうち図16における右側下端寄り位置に配置された支軸20Jに回動可能に支持されている。支軸20Jは、第2部品収容部90Bの奥面と第2樹脂カバー92の奥面とから突出した断面円形の軸体と円筒体とを嵌合してなる。後述する支軸24J,25Jに関しても同様である。また、インサイドオープンレバー20には、支軸20Jから樹脂製ボディ11における横方向の中央側に向かって延びて先端が支軸20Jの軸方向に折り曲げられた押上当接部20Bと、押上当接部20Bから下方に向かって突出し、先端部がワイヤー係止部20Aになった連結突片20Cとが備えられている。また、ワイヤー係止部20Aに、ワイヤー(図示せず)を介してインサイドドアハンドルが接続されている。そして、インサイドドアハンドルの操作により、インサイドオープンレバー20が原点位置から作動位置まで回動し、その間、インサイドオープンレバー20の押上当接部20Bが前述したアウトサイドオープンレバー17の受圧片17Cを押し上げ、アウトサイドオープンレバー17も原点位置から作動位置まで回動する。このとき、オープンリンク19がアンロック位置に配置されていれば、前述したようにドア101が開き、オープンリンク19がロック位置に配置されていれば、ドア101は開かない。 The inside open lever 20 is rotatably supported by a support shaft 20J disposed at a position closer to the lower end on the right side in FIG. 16 of the second component storage unit 90B. The support shaft 20J is formed by fitting a shaft having a circular cross section and a cylindrical body protruding from the back surface of the second component storage portion 90B and the back surface of the second resin cover 92. The same applies to spindles 24J and 25J described later. Further, in the inside open lever 20, a push-up contact portion 20B which extends from the support shaft 20J toward the central side in the lateral direction of the resin body 11 and whose tip is bent in the axial direction of the support shaft 20J A connecting projection 20C is provided, which protrudes downward from the portion 20B and whose tip is a wire locking portion 20A. Further, the inside door handle is connected to the wire locking portion 20A via a wire (not shown). Then, by operating the inside door handle, the inside open lever 20 is pivoted from the home position to the working position, during which the push-up abutment portion 20B of the inside open lever 20 pushes up the pressure receiving piece 17C of the outside open lever 17 described above. The outside open lever 17 also pivots from the home position to the operating position. At this time, if the open link 19 is disposed at the unlock position, the door 101 is opened as described above, and if the open link 19 is disposed at the lock position, the door 101 is not opened.
 アクティブレバー25は、第2部品収容部90Bにおける上下と横の両方向の中央に位置した支軸25Jに回動可能に支持されている。また、アクティブレバー25は、支軸25Jから上方に張り出した第1扇形突片25Aと、支軸25Jから斜め左下方に張り出した扇形の第2扇形突片25Dと、支軸25Jから斜め右側に突出したアクティブ作用アーム25Cとを備えている。 The active lever 25 is rotatably supported by a support shaft 25J located at the center in both the vertical and horizontal directions in the second component storage unit 90B. The active lever 25 has a first fan-shaped projection 25A projecting upward from the support shaft 25J, a sector-shaped second sector-shaped projection 25D extending obliquely downward to the left from the support shaft 25J, and a diagonal right side from the support shaft 25J. And a projecting active acting arm 25C.
 図16に示すように、アクティブ作用アーム25Cの先端部は、オープンリンク19におけるロック解除片19Bに下方から対向している。そして、アクティブレバー25がアンロック位置からロック位置に回動するときに、図14Bから図14Aの変化に示すように、アクティブ作用アーム25Cがロック解除片19Bを押し上げてオープンリンク19をアンロック位置からロック位置に移動する。 As shown in FIG. 16, the tip of the active action arm 25C is opposed to the unlocking piece 19B of the open link 19 from below. Then, when the active lever 25 pivots from the unlock position to the lock position, as shown in the changes in FIG. 14B to FIG. 14A, the active action arm 25C pushes up the unlocking piece 19B to unlock the open link 19. Move from to the lock position.
 図16に示すように、第2扇形突片25Dの下端部からはワイヤー結合片25Eが張り出している。そのワイヤー結合片25Eには、図示しないワイヤーを介してドア101の内面に備えたロック操作部が接続されている。そして、ロック操作部を操作することで、アクティブレバー25をアンロック位置とロック位置とに切り替えることができる。 As shown in FIG. 16, the wire connection piece 25E protrudes from the lower end of the second fan-shaped projection 25D. A lock operating portion provided on the inner surface of the door 101 is connected to the wire connection piece 25E via a wire (not shown). Then, by operating the lock operation unit, the active lever 25 can be switched between the unlock position and the lock position.
 アクティブレバー25は、ドア101の内面のロック操作部以外にも車内の集中ロックや無線キー108(図1B参照)によってアンロック位置とロック位置とに切り替えることができる。そのために、図16に示したモータ22が樹脂製ボディ11に取り付けられている。そのモータ22の回転出力軸にはウォームギヤ23が固定され、そのウォームギヤ23に噛合するウォームホイール24が、樹脂ボディ本体90に備えた支軸24Jに対して回転可能に支持されている。そして、ウォームホイール24に備えた1対の回転押圧突部24A(図16では、一方の回転押圧突部24Aのみが示されている)と第1扇形突片25Aの内面に備えた図示しない凹凸部との係合により、モータ22の動力をアクティブレバー25に伝達して、アクティブレバー25を、ロック位置とアンロック位置とに切り替えることができる。 The active lever 25 can be switched between the unlock position and the lock position by means of the in-vehicle centralized lock or the wireless key 108 (see FIG. 1B) as well as the lock operation portion on the inner surface of the door 101. For that purpose, the motor 22 shown in FIG. 16 is attached to the resin body 11. A worm gear 23 is fixed to a rotational output shaft of the motor 22 and a worm wheel 24 meshing with the worm gear 23 is rotatably supported on a support shaft 24 J provided on the resin body main body 90. Then, a pair of rotation pressing protrusions 24A provided on the worm wheel 24 (only one rotation pressing protrusion 24A is shown in FIG. 16) and unevenness (not shown) provided on the inner surface of the first sector protrusion 25A. By engaging with the part, the power of the motor 22 can be transmitted to the active lever 25 to switch the active lever 25 between the locked position and the unlocked position.
 なお、アクティブレバー25は、ドア101に備えたキーシリンダ102にキー103(図1B参照)を挿入してキー操作することによってもアンロック位置とロック位置とに切り替えることができる。そのキーシリンダ102に連結されるキー連結レバー32は、図1Aに示すように、樹脂ボディ本体90の裏面側に配置され、その回動軸が樹脂ボディ本体90を貫通し、図16に示すように第2部品収容部90B内に配置された中継レバー31に連結されている。また、中継レバー31とアクティブレバー25との間は、連結バー30によって連結されている。これにより、キーシリンダ102の操作によってもアクティブレバー25がアンロック位置とロック位置とに切り替えられる。 The active lever 25 can also be switched between the unlock position and the lock position by inserting the key 103 (see FIG. 1B) into the key cylinder 102 provided in the door 101 and performing key operation. As shown in FIG. 1A, the key connecting lever 32 connected to the key cylinder 102 is disposed on the back side of the resin body main body 90, and the pivoting axis passes through the resin body main body 90, as shown in FIG. Are connected to the relay lever 31 disposed in the second component storage unit 90B. The relay lever 31 and the active lever 25 are connected by a connecting bar 30. Thus, the active lever 25 is also switched between the unlock position and the lock position by the operation of the key cylinder 102.
 さて、本実施形態のドアロック装置10のうち、アウトサイドオープンレバー17を回動可能に支持した支軸97は、本発明に係る嵌合構造200が適用されている。以下、支軸97の構造について説明する。 By the way, in the door lock device 10 of the present embodiment, the support structure 97 according to the present invention is applied to the support shaft 97 that rotatably supports the outside open lever 17. The structure of the support shaft 97 will be described below.
 即ち、図11に示すように、第1樹脂カバー91の内面下端部からは、第1部品収容部90Aの奥壁90C(図11の紙面の表側)に向かって支持突部95が突出している。図4に示すように、支持突部95は、第1樹脂カバー91から突出した第1円筒部95Aと、その第1円筒部95Aの先端を閉塞する先端壁95Bから突出した第2円筒部95Cとを備えている。また、第2円筒部95Cは、第1円筒部95Aの中心に対して下方に偏心した位置に配置されている。なお、第1円筒部95Aの外側には、トーションコイルバネ14Sのコイル部が遊嵌している。 That is, as shown in FIG. 11, from the lower end portion of the inner surface of the first resin cover 91, the support projection 95 protrudes toward the back wall 90C (the front side of the sheet of FIG. 11) of the first component storage portion 90A. . As shown in FIG. 4, the support projection 95 includes a first cylindrical portion 95A protruding from the first resin cover 91, and a second cylindrical portion 95C protruding from a tip wall 95B closing the tip of the first cylindrical portion 95A. And have. Further, the second cylindrical portion 95C is disposed at a position eccentric downward with respect to the center of the first cylindrical portion 95A. The coil portion of the torsion coil spring 14S is loosely fitted to the outside of the first cylindrical portion 95A.
 図10に示すように、樹脂ボディ本体90には、第1部品収容部90Aの奥壁90Cに回動支持筒96(本発明の「メイン軸体」に相当する)が突出形成されている。その回動支持筒96は先端開放の円筒状をなすと共に、その開放面に、本発明に係る先端傾斜面96Fが形成されている。図17に示すように、回動支持筒96は、その先端が中心軸J1に対して斜めに輪切りにされた鋭角な楔形(竹槍の先端のような形状)をなしており、回動支持筒96の開放面の全体が、回動支持筒96の中心軸J1を斜めに横切る平坦な先端傾斜面96Fで構成されている。回動支持筒96の先端開口縁はテーパー状に面取りされており、回動支持筒96の先端外周縁はR面取りされている。なお、先端傾斜面96Fとは、回動支持筒96の筒壁の先端面を構成する傾斜面と、その傾斜面と面一でかつ筒壁の内側の開口領域を中心軸J1に対して斜めに横切る仮想の傾斜面とから構成される傾斜面のことを意味する。 As shown in FIG. 10, a pivoting support cylinder 96 (corresponding to the “main shaft” of the present invention) is formed in a projecting manner on the back wall 90C of the first component housing 90A in the resin body main body 90. The rotation support cylinder 96 has a cylindrical shape with an open tip, and a tip inclined surface 96F according to the present invention is formed on the open surface. As shown in FIG. 17, the pivoting support cylinder 96 has an acute-angled wedge shape (shape like the tip of a bamboo basket) whose tip is diagonally cut off with respect to the central axis J1. The whole of the open surface 96 is constituted by a flat tip inclined surface 96 F diagonally crossing the central axis J 1 of the rotation support cylinder 96. The tip opening edge of the rotation support cylinder 96 is chamfered in a tapered shape, and the tip outer peripheral edge of the rotation support cylinder 96 is R-chamfered. Note that the tip end inclined face 96F is an inclined face that constitutes the end face of the cylindrical wall of the rotation support cylinder 96, and the opening area on the inner side of the cylindrical wall is oblique to the central axis J1. Means an inclined surface composed of a virtual inclined surface crossing the
 図4に示すように、奥壁90Cのうち回動支持筒96に囲まれた部分の中心には、貫通孔96Aが形成されている。そして、アウトサイドオープンレバー17に貫通形成された円形の嵌合孔17H及びトーションコイルバネ18のコイル部18Cに回動支持筒96を挿入した状態で、第1樹脂カバー91を樹脂ボディ本体90に組み付けると、回動支持筒96の内側に、本発明の「サブ軸体」に相当する第2円筒部95Cが挿入された状態になる。そして、貫通孔96Aに挿通したセルフタッピングスクリューである螺子N2を、第2円筒部95Cの中心を貫通したネジ下穴95Dに締め付けることで、第1樹脂カバー91が樹脂ボディ本体90に固定されると共に、第2円筒部95Cと回動支持筒96が一体になってアウトサイドオープンレバー17及びトーションコイルバネ18を支持した支軸97が構成される。 As shown in FIG. 4, a through hole 96A is formed at the center of a portion of the back wall 90C surrounded by the rotation support cylinder 96. Then, the first resin cover 91 is assembled to the resin body main body 90 in a state in which the rotation support cylinder 96 is inserted in the circular fitting hole 17H formed through the outside open lever 17 and the coil portion 18C of the torsion coil spring 18 The second cylindrical portion 95C corresponding to the “sub-shaft” of the present invention is inserted into the inside of the rotation support cylinder 96. Then, the first resin cover 91 is fixed to the resin body main body 90 by tightening the screw N2, which is a self-tapping screw inserted into the through hole 96A, into the screw lower hole 95D penetrating the center of the second cylindrical portion 95C. At the same time, the second cylindrical portion 95C and the rotation support cylinder 96 are integrated to form a support shaft 97 on which the outside open lever 17 and the torsion coil spring 18 are supported.
 なお、回動支持筒96の内径と第2円筒部95Cの外径とは略同一であり、それらは殆どガタの無い状態で嵌合している。また、同様に、回動支持筒96の外径と、アウトサイドオープンレバー17の嵌合孔17Hの内径とは略同一であり、アウトサイドオープンレバー17と回動支持筒96とは殆どガタの無い状態で嵌合している。なお、嵌合孔17Hは円形でなくてもよく、例えば、回動支持筒96の外周面に外接する多角形でもよい。また、回動支持筒96の中心孔は断面円形でなくてもよく、例えば、第2円筒部95Cの外周面に外接する断面多角形でもよい。 Note that the inner diameter of the rotation support cylinder 96 and the outer diameter of the second cylindrical portion 95C are substantially the same, and they are fitted with almost no rattling. Similarly, the outer diameter of the rotation support cylinder 96 and the inner diameter of the fitting hole 17H of the outside open lever 17 are substantially the same, and the outside open lever 17 and the rotation support cylinder 96 have almost no play. It is fitting without the condition. The fitting hole 17H may not be circular, and may be, for example, a polygon circumscribing the outer peripheral surface of the rotation support cylinder 96. The center hole of the rotation support cylinder 96 may not be circular in cross section, and may be, for example, a polygonal cross section circumscribing the outer peripheral surface of the second cylindrical portion 95C.
 ここで、回動支持筒96の内側に第2円筒部95Cが嵌合されかつ、螺子N1,N2によって樹脂ボディ本体90と第1樹脂カバー91とが一体に固定されたことで、支軸97は両持ち構造になっている。両持ち構造になったことで、支軸97は、トーションコイルバネ18によって付勢されたアウトサイドオープンレバー17からの負荷に対する十分な強度を有することになり、アウトサイドオープンレバー17の支持状態が安定する。 Here, the second cylindrical portion 95C is fitted to the inside of the rotation support cylinder 96, and the resin body main body 90 and the first resin cover 91 are integrally fixed by the screws N1 and N2. Has a double-ended structure. Due to the double-supported structure, the support shaft 97 has sufficient strength against the load from the outside open lever 17 biased by the torsion coil spring 18, and the support state of the outside open lever 17 is stable. Do.
 本実施形態のドアロック装置10の構成に関する説明は以上である。次に、本実施形態のドアロック装置10の製造方法について説明する。 The description regarding the structure of the door lock device 10 of this embodiment is above. Next, a method of manufacturing the door lock device 10 of the present embodiment will be described.
 まずは、モータ22、ウォームホイール24、アクティブレバー25等の各種部品(図16参照)を樹脂ボディ本体90の第2部品収容部90B内に組み付ける。 First, various components (see FIG. 16) such as the motor 22, the worm wheel 24, and the active lever 25 are assembled in the second component storage portion 90B of the resin body main body 90.
 次に、第2部品収容部90Bの側面開口に第2樹脂カバー92を被せて、支軸20J,24J,25Jを構成する軸体と円筒体(図示せず)とを凹凸嵌合させ、さらに、樹脂ボディ本体90の外縁部と第2樹脂カバー92の外縁部とを互いに重ね合わせてそれらを、例えば、レーザー溶着によって接合する。 Next, the second resin cover 92 is put on the side opening of the second component storage section 90B, and the shaft constituting the spindles 20J, 24J, 25J and the cylindrical body (not shown) are engaged with each other in a concavo-convex manner. The outer edge portion of the resin body main body 90 and the outer edge portion of the second resin cover 92 are superimposed on each other, and they are joined by, for example, laser welding.
 次に、オープンリンク19及びトーションコイルバネ29を予め一体に組み付けておいたアウトサイドオープンレバー17を樹脂ボディ本体90の第1部品収容部90A内に組み付ける。即ち、アウトサイドオープンレバー17に形成された円形の嵌合孔17Hの内側に、第1部品収容部90Aの奥壁90Cから突出した回動支持筒96を挿入してそれらを嵌合させる。ここで、本発明に係る嵌合構造200では、回動支持筒96の先端の開放面に中心軸J1を斜めに横切る先端傾斜面96Fが形成されており、回動支持筒96の先端が鋭角に尖った楔形をなしているから、嵌合作業を始める前に嵌合孔17Hと回動支持筒96とを芯出ししておく必要はなく、図17Aに示すように、嵌合孔17Hとその断面よりも十分に小さい回動支持筒96の最先端部96Pとを、アバウトに位置合わせする(詳細には、回動支持筒96の最先端部96Pと嵌合孔17Hとを一直線上に配置する)だけで、図17Bに示すように、容易に回動支持筒96の最先端部96Pを嵌合孔17Hに通すことができる。そして、回動支持筒96の最先端部96Pさえ嵌合孔17Hに挿入することができれば、その後の嵌合作業の過程においても、回動支持筒96の先端傾斜面96Fの外縁部と嵌合孔17Hの縁部とが途中で突き当たって作業が滞ることはない。詳細には、嵌合作業の最初に回動支持筒96と嵌合孔17Hの中心がずれていても、その後の嵌合作業の過程で中心同士が徐々に近づいて、最終的には、図17Cに示すように、回動支持筒96と嵌合孔17Hとが芯出しされる。 Next, the outside open lever 17 in which the open link 19 and the torsion coil spring 29 are integrally assembled in advance is assembled in the first component accommodating portion 90A of the resin body main body 90. That is, the rotary support cylinder 96 projecting from the back wall 90C of the first component storage portion 90A is inserted into the inside of the circular fitting hole 17H formed in the outside open lever 17 and these are fitted. Here, in the fitting structure 200 according to the present invention, a tip inclined surface 96F obliquely crossing the central axis J1 is formed on the open surface of the tip of the rotation support cylinder 96, and the tip of the rotation support cylinder 96 has an acute angle. It is not necessary to center the fitting hole 17H and the rotation support cylinder 96 before starting the fitting operation, as shown in FIG. 17A. Position the tip end 96P of the rotation support cylinder 96, which is sufficiently smaller than the cross section thereof, in the outline (in detail, align the tip end 96P of the rotation support cylinder 96 and the fitting hole 17H in a straight line) Only by the arrangement, as shown in FIG. 17B, the foremost end 96P of the rotation support cylinder 96 can be easily passed through the fitting hole 17H. Then, as long as the foremost end 96P of the pivoting support cylinder 96 can be inserted into the fitting hole 17H, the distal end inclined surface 96F of the pivoting support cylinder 96 is engaged with the outer edge portion of the pivoting support cylinder 96 also The edge of the hole 17H may hit halfway and the work will not be delayed. Specifically, even if the centers of the rotation support cylinder 96 and the fitting hole 17H are shifted at the beginning of the fitting operation, the centers gradually approach each other in the process of the subsequent fitting operation, and finally, as shown in FIG. As shown in 17C, the rotation support cylinder 96 and the fitting hole 17H are centered.
 次に、トーションコイルバネ18のコイル部18Cに回動支持筒96に挿入する。挿入を終えたら、トーションコイルバネ18の一方のバネ端末部をアウトサイドオープンレバー17の係止突部17Xに係止させると共に、他方のバネ端末部を樹脂ボディ本体90のストッパ部90Sに係止させる。すると、トーションコイルバネ18が捻れて、アウトサイドオープンレバー17がストッパ部90Sに当接した原点位置に付勢されると共に、トーションコイルバネ18のコイル部18Cの内面が回動支持筒96の外側面の一部に当接して、回動支持筒96の中心に対してコイル部18Cの中心が偏心した位置に配置される。このとき、コイル部18Cは、回動支持筒96の外周面のうち、先端傾斜面96Fと反対側部分に当接するように配置される。換言すれば、回動支持筒96の外側にトーションコイルバネ18が偏心状態で組み付けられたときに、コイル部18Cの内面が接近する部分と反対側部分に先端傾斜面96Fが形成されている。このようにしたことで、回動支持筒96の長さを短く抑えたままで、回動支持筒96からのコイル部18Cの抜けを防止することができる。 Next, the rotary support cylinder 96 is inserted into the coil portion 18C of the torsion coil spring 18. After the insertion, the one spring end of the torsion coil spring 18 is locked to the locking projection 17X of the outside open lever 17, and the other spring end is locked to the stopper 90S of the resin body 90. . Then, the torsion coil spring 18 is twisted and the outside open lever 17 is urged to the home position where it abuts against the stopper portion 90S, and the inner surface of the coil portion 18C of the torsion coil spring 18 is the outer surface of the rotation support cylinder 96. The coil portion 18C is disposed at a position where the center of the coil portion 18C is eccentric with respect to the center of the rotation support cylinder 96 while abutting a part. At this time, the coil portion 18C is disposed so as to abut the portion of the outer peripheral surface of the rotation support cylinder 96 opposite to the tip inclined surface 96F. In other words, when the torsion coil spring 18 is assembled eccentrically to the outside of the rotation support cylinder 96, the tip inclined surface 96F is formed on the opposite side to the portion to which the inner surface of the coil portion 18C approaches. By doing this, it is possible to prevent the coil portion 18C from coming off the rotation support cylinder 96 while keeping the length of the rotation support cylinder 96 short.
 ここで、本実施形態では、回動支持筒96の基端側にアウトサイドオープンレバー17が組み付けられ、先端側にトーションコイルバネ18が組み付けられているが、この配置を逆にした場合には、回動支持筒96の長大化を招く虞がある。即ち、アウトサイドオープンレバー17の嵌合孔17Hの内側に先端傾斜面96Fが配置されると、アウトサイドオープンレバー17の支持状態が不安定になるので、先端傾斜面96Fの全体を嵌合孔17Hから突出させる必要があり、その分、回動支持筒96が長くなる。この点、本実施形態の構成によれば、回動支持筒96の長さを短く抑えることができる。 Here, in the present embodiment, the outside open lever 17 is assembled on the proximal end side of the rotation support cylinder 96, and the torsion coil spring 18 is assembled on the distal end side. There is a possibility that the rotation support cylinder 96 may be lengthened. That is, since the support state of the outside open lever 17 becomes unstable when the front end inclined surface 96F is disposed inside the fitting hole 17H of the outside open lever 17, the whole front end inclined surface 96F is a fitting hole It is necessary to make it project from 17H, and the rotation support cylinder 96 becomes longer accordingly. In this respect, according to the configuration of the present embodiment, the length of the rotation support cylinder 96 can be kept short.
 トーションコイルバネ18の組み付けが完了したら、第1樹脂カバー91を樹脂ボディ本体90に組み付ける。即ち、第1樹脂カバー91の内面側(補強板94側)を第1部品収容部90Aの奥壁90Cに対向させて近づけ、第1樹脂カバー91の内面側全体を第1部品収容部90A内に収めると共に、第1樹脂カバー91のサイド突壁91Aの縁部を第2樹脂カバー92の縁部に対して外側から重ね合わせる。すると、サイド突壁91Aの縁部に形成された係止孔91A1と、第2樹脂カバー92の縁部に形成された係止突起92Aとが係止する。また、第1樹脂カバー91から突出形成された支持突部95の第2円筒部95Cが、回動支持筒96の内側に挿入される。これらにより、樹脂ボディ本体90と第1樹脂カバー91とが仮固定される。 When the assembly of the torsion coil spring 18 is completed, the first resin cover 91 is assembled to the resin body main body 90. That is, the inner surface side (the reinforcing plate 94 side) of the first resin cover 91 is brought close to the back wall 90C of the first component storage portion 90A, and the entire inner surface side of the first resin cover 91 is in the first component storage portion 90A. And the edge of the side protruding wall 91A of the first resin cover 91 is overlapped with the edge of the second resin cover 92 from the outside. Then, the locking hole 91A1 formed in the edge of the side protruding wall 91A and the locking protrusion 92A formed in the edge of the second resin cover 92 are locked. Further, the second cylindrical portion 95C of the support projection 95 formed to project from the first resin cover 91 is inserted into the inside of the rotation support cylinder 96. As a result, the resin body 90 and the first resin cover 91 are temporarily fixed.
 ここで、回動支持筒96と第2円筒部95Cの嵌合作業時には、回動支持筒96が第1樹脂カバー91に覆われて視認し難くなるが、回動支持筒96の先端に先端傾斜面96Fを設けてあるから、視認し難い回動支持筒96と第2円筒部95Cとの嵌合作業も比較的容易に行うことができる。 Here, at the time of fitting work of the rotation support cylinder 96 and the second cylindrical portion 95C, the rotation support cylinder 96 is covered with the first resin cover 91 and it becomes difficult to visually recognize, but the tip of the rotation support cylinder 96 is the tip. Since the inclined surface 96F is provided, the fitting operation between the rotation support cylinder 96, which is difficult to visually recognize, and the second cylindrical portion 95C can be performed relatively easily.
 詳細には、図17Cに示すように、回動支持筒96の中心軸J1に対して、第2円筒部95Cの中心軸が多少斜めになっていても、その第2円筒部95Cの先端を、先端傾斜面96F側から回動支持筒96の内側に挿し込むことができるから、先端傾斜面96Fを備えていないものに比べて、嵌合作業を容易に行うことができる。 More specifically, as shown in FIG. 17C, even if the central axis of the second cylindrical portion 95C is slightly inclined with respect to the central axis J1 of the rotation support cylinder 96, the tip of the second cylindrical portion 95C is Since it can be inserted into the inside of the rotation support cylinder 96 from the tip inclined surface 96F side, the fitting operation can be easily performed as compared with the one without the tip inclined surface 96F.
 樹脂ボディ本体90と第1樹脂カバー91とを仮固定したら、最後に、第1部品収容部90Aの奥壁90Cに備えた貫通孔90Dに螺子N1を通して、その螺子N1を補強板94の螺子孔94Nに締め付けると共に、奥壁90Cに備えた貫通孔96Aに通した螺子N2を回動支持筒96の内側に挿入された第2円筒部95Cのネジ下穴95Dに締め付ける。これで、第1樹脂カバー91が樹脂ボディ本体90に完全に固定される。また、この固定により支軸97が両持ち構造になり、アウトサイドオープンレバー17及びトーションコイルバネ18の支持状態が安定する。以上がドアロック装置10は製造方法である。 After temporarily fixing the resin body main body 90 and the first resin cover 91, finally, pass the screw N1 through the through hole 90D provided in the back wall 90C of the first component housing 90A and screw the screw N1 into the screw hole of the reinforcing plate 94. The screw N2 is inserted into the through hole 96A provided on the back wall 90C and is fixed to the screw lower hole 95D of the second cylindrical portion 95C inserted inside the rotary support cylinder 96 while being fixed to 94N. Thus, the first resin cover 91 is completely fixed to the resin body 90. Further, by this fixing, the support shaft 97 is double-supported, and the support state of the outside open lever 17 and the torsion coil spring 18 is stabilized. The above is the manufacturing method of the door lock device 10.
 このように、本実施形態の嵌合構造200によれば、回動支持筒96の先端の開放面に、回動支持筒96の中心軸J1を斜めに横切る先端傾斜面96Fを形成したので、嵌合作業を始める前に、嵌合孔17Hと回動支持筒96とを芯出ししておく必要はなく、嵌合孔17Hとその断面よりも十分に小さい回動支持筒96の最先端部96Pとを、アバウトに位置合わせするだけで回動支持筒96の最先端部96Pを容易に嵌合孔17Hに通すことができる。そして、回動支持筒96の最先端部96Pさえ嵌合孔17Hに挿入することができれば、その後の嵌合作業の過程でも、回動支持筒96の先端傾斜面96Fの外縁部と嵌合孔17Hの縁部とが突き当たって作業が滞ることはないので、回動支持筒96に対するアウトサイドオープンレバー17の組み付け作業性を十分に向上させることができる。また、先端傾斜面96Fを設けたことで、回動支持筒96の内側に第2円筒部95Cを嵌合させる作業も比較的容易に行うことができる。つまり、本実施形態によれば、回動支持筒96の内外に対する嵌合部品(アウトサイドオープンレバー17及び第2円筒部95C)の組み付け作業性を向上させることができる。 As described above, according to the fitting structure 200 of the present embodiment, since the tip inclined surface 96F obliquely crossing the central axis J1 of the rotation support cylinder 96 is formed on the open surface of the tip of the rotation support cylinder 96, Before starting the fitting operation, it is not necessary to center the fitting hole 17H and the rotation support cylinder 96, and the tip end of the rotation support cylinder 96 sufficiently smaller than the fitting hole 17H and the cross section thereof The tip end portion 96P of the rotation support cylinder 96 can be easily passed through the fitting hole 17H simply by aligning the position 96P with the outline. The outer edge portion and the fitting hole of the tip inclined surface 96F of the turning support cylinder 96 can be inserted even in the process of the subsequent fitting work, as long as the foremost end 96P of the turning support cylinder 96 can be inserted into the fitting hole 17H. Since the operation does not get stuck due to the end of the edge 17H, the assembling workability of the outside open lever 17 with respect to the rotation support cylinder 96 can be sufficiently improved. Further, by providing the front end inclined surface 96F, the operation of fitting the second cylindrical portion 95C to the inside of the rotation support cylinder 96 can be performed relatively easily. That is, according to the present embodiment, it is possible to improve the assembling workability of the fitting parts (the outside open lever 17 and the second cylindrical portion 95C) with respect to the inside and outside of the rotation support cylinder 96.
 また、本実施形態の回動支持筒96のように、円筒体の内外に嵌合部品を嵌合させて組み付ける嵌合構造では、組み付け作業性の向上を図るために、円筒体の先端外周縁及び先端開口縁に円錐台形状のガイド面を設けることも考えられるが、それらガイド面は、円筒体を構成する筒壁の肉厚の範囲でしか形成することができないため、作業者が実感できる程度にまで作業性を向上させることは困難である。これに対し、本実施形態によれば、上記したガイド面を設けただけの構成に比べて、回動支持筒96の内外に対する嵌合部品の組み付け作業性を十分に向上させることができる。 Further, in the fitting structure in which the fitting parts are fitted and assembled to the inside and the outside of the cylindrical body as in the rotation support cylinder 96 of the present embodiment, the outer peripheral edge of the tip of the cylindrical body to improve the assembling workability. It is also conceivable to provide a truncated cone-shaped guide surface at the tip opening edge, but since these guide surfaces can be formed only within the range of the wall thickness of the cylinder wall constituting the cylinder, it can be felt by the operator It is difficult to improve the workability to some extent. On the other hand, according to the present embodiment, compared with the configuration in which only the above-described guide surface is provided, the assembling workability of the fitting component to the inside and outside of the rotation support cylinder 96 can be sufficiently improved.

Also, as in the case of the pivoting support cylinder 96X of the fitting structure 200X shown in FIG. 18C, the tip sloped surface 96F3 is formed of a curved curved surface that merges the tip sloped surfaces 96F1 and 96F2 shown in FIGS. 18A and 18B. It may be done.

 (4)また、前記実施形態の嵌合構造200では、回動支持筒96の開放面の全体が、先端傾斜面96Fとなっていたが、図19に示す嵌合構造200Yの回動支持筒96Yのように、開放面の一部を中心軸J1に対して直角な直角面96Gとし、残りを、回動支持筒96Yの断面円形の半分よりも大きい先端傾斜面96F4(図19の斜線部分)にしてもよい。 (4) Further, in the fitting structure 200 of the embodiment, the entire open surface of the rotation support cylinder 96 is the tip inclined surface 96F. However, the rotation support cylinder of the fitting structure 200Y shown in FIG. Like 96Y, a part of the open surface is a perpendicular surface 96G perpendicular to the central axis J1, and the remainder is a tip inclined surface 96F4 larger than half of the cross-sectional circular of the rotation support cylinder 96Y (hatched portion in FIG. ) May be used.
 (5)さらに、図20に示す嵌合構造200Zの回動支持筒96Zのように、先端を、回動支持筒96Zの断面円形の半分より小さい第1端面96Kと、その第1端面96Kより基端側に段付き状にずらされた第2端面96Lとに分割して段付き状にしてもよい。なお、第2端面96Lより基端側に段付き状にずらされた第3端面96Mを設けるなど、段付き状に分割された3つ以上の端面を備えたものも、本発明の技術的範囲に含まれる。 (5) Furthermore, as in the case of the pivoting support cylinder 96Z of the fitting structure 200Z shown in FIG. 20, the first end face 96K whose tip is smaller than half of the circular cross section of the pivoting support cylinder 96Z and its first end face 96K It may be divided into a stepped end surface 96L on the base end side to be stepped. The technical scope of the present invention is also provided with three or more end faces divided in a stepped shape, such as providing a third end face 96M shifted in a stepped shape on the base end side of the second end face 96L. include.
 このような嵌合構造200Zであっても、上記実施形態の嵌合構造200と同等の効果を奏する。即ち、嵌合作業の最初の時点で、アウトサイドオープンレバー17の嵌合孔17Hと回動支持筒96Zの中心を一致させる必要はなく、嵌合孔17Hとその断面よりも十分に小さい回動支持筒96の第1端面96Kとを、アバウトに位置合わせするだけで、回動支持筒96Zの第1端面96Kを容易に嵌合孔17Hに通すことができる。そして、その後は、回動支持筒96Zの外面をガイドにして、その外面と嵌合孔17Hの縁部とを摺接させながら挿入を深めていけば、途中で滞ることなく嵌合作業を終えることができるから、回動支持筒96Zとアウトサイドオープンレバー17との嵌合の作業性を十分に向上させることができる。また、回動支持筒96Zの内側に第2円筒部95Cを嵌合させる嵌合作業も容易に行うことができる Even with such a fitting structure 200Z, the same effect as the fitting structure 200 of the above embodiment can be obtained. That is, it is not necessary to make the center of the fitting hole 17H of the outside open lever 17 and the center of the turning support cylinder 96Z coincide with each other at the beginning of the fitting operation, and turning of the fitting hole 17H and its cross section sufficiently smaller The first end face 96K of the rotary support cylinder 96Z can be easily passed through the fitting hole 17H simply by aligning the first end surface 96K of the support cylinder 96 with the about. Then, after that, if the outer surface of the rotation support cylinder 96Z is used as a guide and the insertion is deepened while sliding the outer surface and the edge of the fitting hole 17H, the fitting operation is completed without any delay. Therefore, the workability of the fitting between the rotation support cylinder 96Z and the outside open lever 17 can be sufficiently improved. In addition, the fitting operation for fitting the second cylindrical portion 95C inside the rotation support cylinder 96Z can be easily performed.
