As shown in FIG. 10, a motor 31, a cylindrical worm 32 fixed to the output shaft of the motor 31, and a worm wheel 33 that meshes with the cylindrical worm 32 are provided in the case 29. When the motor 31 is off, the worm wheel 33 returns to the neutral position by the elasticity of the return spring. A socket 34 is provided at the end of the case 29.

前記ソケット３４には３本の端子、即ち、中央のグランド端子３５と、モータ端子３６と、信号端子３７とが設けられる。グランド端子３５の第１接点３５Ａとモータ端子３６はモータ３１に接続され、両端子間が通電されると、モータ３１が回転して、後述するように、前記ラチェット１９はコイルバネ２２の弾力に抗して回転して、前記ラッチ１７を開放し、トランクリッドは開扉可能となる。   The socket 34 is provided with three terminals, that is, a central ground terminal 35, a motor terminal 36, and a signal terminal 37. The first contact 35 </ b> A of the ground terminal 35 and the motor terminal 36 are connected to the motor 31. When the current is passed between both terminals, the motor 31 rotates and the ratchet 19 resists the elasticity of the coil spring 22 as will be described later. Then, the latch 17 is opened and the trunk lid can be opened.

前記グランド端子３５の第２接点３５Ｂは、前記ベースプレート１１に接続され、これによりベースプレート１１はアースされる。前記信号端子３７の接点３７Ａは、ケース２９から外方に突出させ、後述する可動端子３８に接続させる。   The second contact 35B of the ground terminal 35 is connected to the base plate 11, and thereby the base plate 11 is grounded. The contact point 37A of the signal terminal 37 protrudes outward from the case 29 and is connected to a movable terminal 38 to be described later.

A cam body 39 having a gradually increasing radius is integrally formed on the back side of the worm wheel 33.

前記ウォームホイール３３と前記ベースプレート１１との間には、オープンレバー４０（図１５）が設けられる。オープンレバー４０は、略Ｌ型形状を呈しており、軸孔４１に挿通させたピン４２（図１）によりベースプレート１１の軸孔４３に軸止される。オープンレバー４０の右方に伸びる連結アーム４４には、ケーブルヘッド連結部４５が設けられる。ケーブルヘッド連結部４５はＬ型を呈しており、第１ケーブル４６のケーブルヘッド４７が係合する第１溝部４８と、第２ケーブル４９のケーブルヘッド５０が係合する第２溝部５１とが形成される。   An open lever 40 (FIG. 15) is provided between the worm wheel 33 and the base plate 11. The open lever 40 has a substantially L shape, and is fixed to the shaft hole 43 of the base plate 11 by a pin 42 (FIG. 1) inserted through the shaft hole 41. A cable head coupling portion 45 is provided on the coupling arm 44 extending to the right of the open lever 40. The cable head connecting portion 45 has an L shape, and a first groove portion 48 that engages with the cable head 47 of the first cable 46 and a second groove portion 51 that engages with the cable head 50 of the second cable 49 are formed. Is done.

前記第１ケーブル４６は、車内に設けられたトランクオープナー（図示なし）に連結され、前記第２ケーブル４９はトランクリッド又は車体に設けられたキーシリンダー（図示なし）に連結され、これらの操作により、オープンレバー４０は、図１８において、反時計回転する。５２は、オープンレバー４０とベースプレート１１との間に設けたバネである。   The first cable 46 is connected to a trunk opener (not shown) provided in the vehicle, and the second cable 49 is connected to a trunk cylinder or a key cylinder (not shown) provided on the vehicle body. The open lever 40 rotates counterclockwise in FIG. A spring 52 is provided between the open lever 40 and the base plate 11.

前記アクチュエータ１２のケース２９には、図１、９のように、三角形状の薄いフランジ５３とＬ型の受け部５４とが一体的に形成され、フランジ５３は第１ケーブルヘッド４７と第２ケーブルヘッド５０との間に介在させる。受け部５４は、第２ケーブルヘッド５０の近傍下部に位置し、オープンレバー４０が第１ケーブル４６の牽引作用により回転した際、残された第２ケーブルヘッド５０が第２溝部５１から外れないように保持する。   As shown in FIGS. 1 and 9, a triangular flange 53 and an L-shaped receiving portion 54 are integrally formed on the case 29 of the actuator 12, and the flange 53 includes the first cable head 47 and the second cable. It is interposed between the head 50. The receiving portion 54 is located near the lower portion of the second cable head 50, so that the remaining second cable head 50 does not come off from the second groove portion 51 when the open lever 40 is rotated by the pulling action of the first cable 46. Hold on.

前記オープンレバー４０の下方に伸びる当接アーム５５は、図１７のように、前記ラチェット１９の上端部５６に対峙させ、オープンレバー４０が反時計回転すると、ラチェット１９は図１８のように上端部５６が右方に押し出され、これにより、ラチェット１９の爪２５はラッチ１７の段部２６から離脱し、トランクリッドは開扉可能状態となる。   The contact arm 55 extending downward of the open lever 40 is opposed to the upper end portion 56 of the ratchet 19 as shown in FIG. 17, and when the open lever 40 rotates counterclockwise, the ratchet 19 is moved to the upper end portion as shown in FIG. 56 is pushed to the right, whereby the pawl 25 of the ratchet 19 is detached from the step portion 26 of the latch 17 and the trunk lid can be opened.

前記当接アーム５５には、前記ウォームホイール３３のカム体３９と当接可能の当接ピン５７が設けられる。当接ピン５７は、ウォームホイール３３がリターンスプリングの弾力で中立位置にあるときは（図１７）、カム体３９の小径部５８に対峙しており、ウォームホイール３３がモータ３１の動力で時計回転すると、カム体３９により押圧されて、オープンレバー４０は徐々に反時計回転し、図１８のように、当接ピン５７がカム体３９の大径部５９に当接すると、オープンレバー４０の反時計回転により、ラチェット１９を回転させてトランクリッドを開扉可能状態にできる。   The contact arm 55 is provided with a contact pin 57 capable of contacting the cam body 39 of the worm wheel 33. The contact pin 57 faces the small diameter portion 58 of the cam body 39 when the worm wheel 33 is in the neutral position by the elasticity of the return spring (FIG. 17), and the worm wheel 33 is rotated clockwise by the power of the motor 31. Then, it is pressed by the cam body 39, and the open lever 40 gradually rotates counterclockwise. When the contact pin 57 contacts the large diameter portion 59 of the cam body 39 as shown in FIG. By rotating clockwise, the ratchet 19 can be rotated so that the trunk lid can be opened.

前記可動端子３８は、図１９、２０のように、銅板等の導電性材質で形成された細長い端子で、その途中には、非導電性のケース２９に形成した差込溝６０に差込まれる差込部６１を形成し、差込部６１に形成した屈曲部６２をケース２９に螺子６３で固定している。このため、可動端子３８は、アースされているベースプレート１１に接触させることなく、安定した状態で取付けられる。前記可動端子３８の一端６４（図１における上部）は、前記ケース２９から外部に露出させた前記信号端子３７の接点３７Ａに電気的に接続する。   The movable terminal 38 is an elongated terminal formed of a conductive material such as a copper plate, as shown in FIGS. 19 and 20, and is inserted into an insertion groove 60 formed in the non-conductive case 29 in the middle thereof. An insertion portion 61 is formed, and a bent portion 62 formed in the insertion portion 61 is fixed to the case 29 with a screw 63. For this reason, the movable terminal 38 is attached in a stable state without being brought into contact with the grounded base plate 11. One end 64 (upper part in FIG. 1) of the movable terminal 38 is electrically connected to a contact 37A of the signal terminal 37 exposed from the case 29 to the outside.

前述のように、前記ラッチ１７は非導電性の樹脂層２７で覆われており、樹脂層２７には、図５、６に示したように、ラッチ本体からラッチ軸１６の放射方向に広がる薄い絶縁片６５が形成される。絶縁片６５は近接するベースプレート１１と平行である。絶縁片６５の一方側にはラッチ軸１６の軸芯方向に突出する絶縁壁６６を一体的に形成する。   As described above, the latch 17 is covered with the non-conductive resin layer 27, and the resin layer 27 is thin and spreads in the radial direction of the latch shaft 16 from the latch body as shown in FIGS. An insulating piece 65 is formed. The insulating piece 65 is parallel to the adjacent base plate 11. An insulating wall 66 protruding in the axial direction of the latch shaft 16 is integrally formed on one side of the insulating piece 65.

前記可動端子３８の他端６７は、前記ベースプレート１１と接触しないように前記絶縁片６５の上面側に載置される。可動端子３８は、他端６７が絶縁壁６６に当接方向の変形力を備えており、この変形力により、ラッチ１７の回転に応じて、他端６７も図１において左右に移動する。   The other end 67 of the movable terminal 38 is placed on the upper surface side of the insulating piece 65 so as not to contact the base plate 11. The other end 67 of the movable terminal 38 has a deforming force in a contact direction with the insulating wall 66, and the other end 67 also moves left and right in FIG.

前記ベースプレート１１には、図２のように、切り起こしにより形成したアース端子６８を形成する。アース端子６８は、ラッチ１７が図１のようにラッチ位置にあるときは、可動端子３８の他端６７は図１において左方に移動し、可動端子３８はアース端子６８に対して離間した状態に保たれる。しかし、ラチェット１９がラッチ１７から外れて、トランクリッドが開扉されると、ラッチ１７は時計回転して、他端６７は右方に移動し、可動端子３８はアース端子６８に接触する。   The base plate 11 is formed with a ground terminal 68 formed by cutting and raising as shown in FIG. When the latch 17 is in the latched position as shown in FIG. 1, the other end 67 of the movable terminal 38 moves to the left in FIG. 1, and the movable terminal 38 is separated from the ground terminal 68. To be kept. However, when the ratchet 19 is released from the latch 17 and the trunk lid is opened, the latch 17 rotates clockwise, the other end 67 moves to the right, and the movable terminal 38 contacts the ground terminal 68.

このように、開扉により可動端子３８がアース端子６８に接触すると、アースとして作用しているベースプレート１１を介して、可動端子３８が接続された信号端子３７は、グランド端子３５に電気的に接続され、もって、トランクリッドの開扉を検出できる。このようにして検出したトランクリッドの開扉は、室内灯（トランクルーム灯）の点灯や、インストルメントパネルの警告灯の点灯等に使用される。   Thus, when the movable terminal 38 comes into contact with the ground terminal 68 by opening the door, the signal terminal 37 to which the movable terminal 38 is connected is electrically connected to the ground terminal 35 via the base plate 11 acting as the ground. Thus, the opening of the trunk lid can be detected. The opening of the trunk lid detected in this way is used for lighting a room light (trunk room light), lighting a warning light on the instrument panel, and the like.

なお、前記絶縁壁６６は、絶縁片６５の一方側のみにではなく、他方側にも形成することができ、このように絶縁片６５の両側に形成すると、可動端子３８の他端６７は、凹部に囲まれることになって絶縁片６５からの脱落が一層防止される。   The insulating wall 66 can be formed not only on one side of the insulating piece 65 but also on the other side. When the insulating wall 65 is formed on both sides of the insulating piece 65 in this way, the other end 67 of the movable terminal 38 is By being surrounded by the recess, the falling off from the insulating piece 65 is further prevented.

前記ラッチ装置１０の上部側（表面側）は、樹脂カバー６９で覆われる。   The upper side (surface side) of the latch device 10 is covered with a resin cover 69.
