The spring mounting portion 51e is a portion located on the substantially opposite side to the hook portion 51c with the shaft hole 51a as a boundary, and is formed from the shaft hole 51a in the radially outward direction. 51e1 is resin-molded.

  A ratchet 52 is rotatably attached to the ratchet shaft 54. The ratchet 52 is formed by press-molding a metal plate, and has a working hole 52e in addition to a shaft hole 52a, a contact portion 52b, an engagement portion 52c, and a spring mounting portion 52d. The contact portion 52b is a portion extending radially outward from the shaft hole 52a. As shown in FIG. 4A, the contact portion 52b contacts the locking portion 51d of the latch 51 rotated to the open position, and the latch 51 is opened. When rotating from the position to the latch position, it comes into sliding contact with the locking portion 51d. The engaging portion 52c is a recess formed on the outer peripheral surface extending from the shaft hole 52a beyond the contact portion 52b in the radially outward direction. When the latch 51 is rotated to the latch position, the engagement portion 52c is in contact with the contact portion 52b. Via the end surface 52c1 serving as a boundary, it is possible to contact and engage with the locking portion 51d of the latch 51 described above. The spring mounting portion 52d is a portion extending beyond the engaging portion 52c from the shaft hole 52a, and a spring mounting hole 52d1 is formed at the center in the width direction. The working end portion 52e is a portion that extends beyond the spring mounting portion 52d from the shaft hole 52a, and is bent so as to be substantially parallel to the upper region 3B of the base plate 3.

  Further, as shown in FIG. 4, a tension coil spring 55 is installed between the spring mounting portion 51 e of the latch 51 and the spring mounting portion 52 d of the ratchet 52. The tension coil spring 55 constantly biases the latch 51 so that the latch 51 rotates in the open position direction (clockwise in FIG. 4), and always biases the ratchet 52 so that the ratchet 52 is in close contact with the latch 51. To do. As a result, as shown in FIG. 4A, when the latch 51 is located at the open position, the latch 51 abuts against the inner wall surface of the rib 31 provided in the lower region 3A and stops, and the ratchet 52 The contact portion 52b contacts the outer periphery of the locking portion 51d of the latch 51.

Further, as shown in FIG. 4C, when the latch 51 is located at the latch position, when the ratchet 52 is rotated counterclockwise so as to be detached from the latch 51, the ratchet 52 is detached from the latch 51, Due to the urging force acting on 51, the latch 51 rotates in the open position direction (clockwise in FIG. 4).

  When the trunk lid is in an open state with respect to the vehicle main body, the latch 51 and the ratchet 52 configured as described above are arranged in the open position as shown in FIG. When the trunk lid is closed from this state, the striker S provided on the vehicle body side enters the striker entry groove 32, and eventually the striker S comes into contact with the engagement groove 51b of the latch 51. As a result, the latch 51 rotates in the latch position direction (counterclockwise in FIG. 4) against the urging force of the tension coil spring 55. During this time, the ratchet 52 is brought into sliding contact with the outer peripheral surface of the locking portion 51 d of the latch 51 by the urging force of the tension coil spring 55.

  When the trunk lid is further closed from the above-described state, the amount of the striker S entering the striker entry groove 32 gradually increases, so that the latch 51 further rotates in the direction of the latch position, and as shown in FIG. The locking portion 51d reaches the engaging portion 52c of the ratchet 52 (latch position). In this state, the latching portion 51d of the latch 51 comes into contact with and engages with the engaging portion of the ratchet 52, so that the latch 51 is in the open position direction (in FIG. 4) against the urging force of the tension coil spring 55. (Clockwise) is prevented from rotating. In addition, since the hook portion 51c of the latch 51 is arranged so as to cross the striker entry groove 32, the hook portion 51c causes the striker S to move away from the striker entry groove 32, that is, the trunk lid The opening operation with respect to the vehicle body is prevented (latched state).

  Further, as shown in FIG. 4C, when the ratchet 52 is rotated in the direction of releasing from the latch 51 (clockwise in FIG. 4) against the biasing force of the tension coil spring 55 from the latched state, the engagement of the latch 51 is increased. The abutting engagement state between the stopper 51d and the engaging portion 52c of the ratchet 52 is released, and the latch 51 is rotated in the opening position direction (clockwise in FIG. 4) by the urging force of the tension coil spring 55 to reach the opening position. . At this time, as shown in FIG. 4A, the striker entry groove 32 is opened, and the striker S moves in a direction away from the striker entry groove 32, so that the trunk lid can be opened with respect to the vehicle body. It becomes like this.

  As shown in FIG. 3, an open lever shaft 61 is fixed to a position that is approximately the center of the upper region 3 </ b> B of the base plate 3. An open lever 6 is rotatably attached to the open lever shaft 61. The open lever 6 is formed by press-molding a metal plate and has an action part 6a and an operation part 6b.

  The action part 6a is a part for rotating the ratchet 52 engaged with the latching part 51d of the latch 51 in a direction away from the latch 51, and extends downward from the open lever shaft 61 to the left side. The action end 6a1 of the action part 6a is bent so as to face the front of the vehicle, and is opposed to the action end 52e of the ratchet 52 engaged with the locking part 51d of the latch 51 with a slight gap (standby) Position).

  The operation portion 6b is a portion to which an operation force or the like is applied, and extends from the open lever shaft 61 to the right or slightly below, and is then bent toward the front of the vehicle to become a base portion 6b1, and from there to two directions Branch. A cable mounting groove (not shown) is formed in the base 6b1. The cable installation groove is a portion to which a cable (not shown) linked to a trunk lever provided under the driver's seat is connected. When the trunk lever is opened, the open lever 6 is operated in the operation direction ( It rotates in the counterclockwise direction in FIG.

  One of the branches from the base 6b1 extends outward from between the base plate 3 and the protector cover 4 (see FIG. 1), becomes an operation end 6b2, and an operation handle 62 is attached thereto. The operation handle 62 is formed of a resin material capable of storing light, and is provided with marks such as arrows indicating the operation direction. Thereby, the operation handle 62 and the operation direction can be identified even in the dark.

  The other branched from the base portion 6b1 extends downward to become a spring mounting portion 6b3, and a hook (not shown) for hooking one end of the tension coil spring 63 is formed at the end portion. A tension coil spring 63 is installed between the spring mounting portion 6 b 3 of the open lever 6 and the spring mounting portion 31 a provided on the rib 31 of the base plate 3. The tension coil spring 63 constantly biases the open lever 6 so that the open lever 6 returns to the standby position. Thereby, even if the operation handle 62 is opened, when the hand is released from the operation handle 62, the open lever 6 always rotates toward the standby position.

  A driven portion 6a2 is provided between the operation portion 6b and the action end 6a1 of the open lever 6 at a position overlapping the base plate 3 of the action portion 6a. As will be described later, the driven portion 6a2 is pressed by the actuator 7 in the electric release type latch device 1, and in the manual release type latch device 2 is bent at a portion that contacts the stopper portion 81 of the case 8, It is formed in an “L” shape.

  6 is a front view showing the internal configuration of the electric release type latch device, and FIG. 7 is a diagram showing the internal configuration including the configuration of the actuator shown in FIG. FIG. 8 is a diagram showing an internal configuration of the actuator.

  As shown in FIG. 6, the electric release type latch device 1 rotates the ratchet 52 in the direction of detaching from the latch 51 (counterclockwise in FIG. 6) by power, and the latch 51 and the ratchet 52 are in a contact engagement state. The actuator 7 is mounted.

  The electric release type latch device 1 described here is configured to release the ratchet 52 from the latch 51 when the actuator 7 opens the open lever 6, and is attached to the base plate 3 as shown in FIG. . The actuator 7 opens the open lever 6 by pressing a driven portion 6a2 provided on the open lever 6, and includes a case 71 (see FIG. 6), a motor 72, a worm 73, and a worm wheel 74. .

  The motor 72 serves as a drive source for the actuator 7, and the worm 73 described above is attached to the output shaft thereof. The motor 72 and the worm wheel 74 are arranged in a case so that the worm 73 and the worm wheel 74 are engaged with each other. 71 is attached.

  A protrusion 74 b is provided on the front surface of the worm wheel 74, and a stopper (not shown) that contacts the protrusion 74 b is attached to the inside of the case 71. A return spring (not shown) is attached between the worm wheel 74 and the case 71. Accordingly, when the motor 72 rotates, the worm wheel 74 rotates counterclockwise in FIG. 7A and the elastic restoring force is stored in the return spring. On the other hand, when the motor 72 stops, the elastic restoring force of the return spring causes The worm wheel 74 rotates clockwise in FIG. 7-2, and the protrusion 74b comes into contact with the stopper. Thereby, the worm wheel 74 stops at the same position (stop position).

  On the rear surface of the worm wheel 74, there is an electric release type stopping means for pressing the driven portion 6a2 provided on the open lever 6 and stopping the open lever 6 when the worm wheel 74 is stopped at the stop position. A cam 74a of the worm wheel 74 is provided. The actuator 7 is attached to the base plate 3 so that the driven portion 6a2 of the open lever 6 is positioned between the worm wheel 74 and the base plate 3. Further, the cam 74a is arranged so as to be positioned on the rotation locus of the driven portion 6a2. Therefore, the cam 74a faces the driven portion 6a2 provided on the open lever 6 when the worm wheel 74 is stopped at the stop position. When the worm wheel 74 rotates, the cam 74a presses the driven portion 6a2 provided on the open lever 6. To do. Thereby, the open lever 6 is opened by the actuator 7.

  On the outside of the case 71 described above, a stopper 71a is provided for hitting when the open lever 6 is opened. A rib (not shown) is provided outside the case 71. The rib is formed so that the operation handle 62 overlaps when the open lever 6 is in the standby position. Even when an article housed in the trunk room hits the operation handle 62, the operation handle 62 is supported in contact with the rib. Therefore, deformation is suppressed.

  The case 71 is provided with a signal terminal 71b for detecting the position of the latch 51. The signal terminal 71b obtains a conduction signal by contacting the switch pin 33 provided upright on the base plate 3 when the latch 51 is moved to the open position. Further, the case 71 has a connector 71c (see FIG. 6). The connector 71c supplies power to the motor 72 described above and is connected to the signal terminal 71b to output a conduction signal.

  In the electric release type latch device 1 described above, the open lever 6 rotates clockwise in FIG. 7-1 and counterclockwise in FIG. 7-2 by the urging force of the tension coil spring 63. The cam 74a of the worm wheel 74, which constitutes an electric release type stop means for stopping the open lever 6 when the worm wheel 74 is stopped at the stop position, is disposed so as to be positioned on the rotation locus of FIG. Since the driven portion 6a2 comes into contact with the cam 74a formed on the worm wheel 74, the driven portion 6a2 always stops at the same position (standby position). Thereby, the electric release type latch device 1 described above does not need to be provided with a stopper portion for stopping the open lever 6 at the standby position. Further, the driven portion 6a2 of the open lever 6 is located between the operation portion 6b of the open lever 6 and the action end portion 6a1, and overlaps the base plate 3 between the base plate 3 and the rear surface of the worm wheel 74. Since rational arrangement is possible, the apparatus can be miniaturized.

  In the electric release type latch device 1 described above, the driven portion 6a2 provided on the open lever 6 is positioned between the base plate 3 and the case 71, so that the size of the device can be reduced. Further, since the cam 74a provided on the worm wheel 74 presses the driven portion 6a2 provided on the open lever 6, the apparatus can be downsized in this respect as well. In addition, since the rotation of the worm wheel 74 is directly transmitted to the open lever 6, power transmission is efficient.

FIG. 9 is a front view showing an internal configuration of the manual release type latch device. FIG. 10 is a diagram showing an internal configuration including the case shown in FIG.
As shown in FIGS. 9 and 10, the manual release type latch device 2 manually rotates the ratchet 52 in a direction to detach from the latch 51 (counterclockwise in FIG. 9), and the latch 51 and the ratchet 52 come into contact with each other. The engagement state is released, and only the point that the stopper portion 81 of the case 8 constituting the manual release type stop means is mounted in place of the actuator 7 described above is different from the electrical release type latch device 1.

  The case 8 is provided with a signal terminal 71b for detecting the position of the latch 51. The signal terminal 71b obtains a conduction signal by contacting the switch pin 33 provided upright on the base plate 3 when the latch 51 is moved to the open position. The case 8 has a connector 81c. The connector 81c is connected to the signal terminal 71b and outputs a conduction signal.

  The case 8 is formed with a stopper portion 81. The stopper portion 81 is for always stopping the open lever 6 at the same position (standby position). In the electrically releasing latch device 1, like the cam 74 a formed on the worm wheel 74, the open lever 6 is driven. By being arranged so as to be positioned on the rotation locus of the part 6a2, it is provided so as to contact the driven part 6a2 of the open lever 6.

  Further, a stopper 71a is provided on the outside of the case 8 when the open lever 6 is opened. Further, a rib is provided on the outside of the case 8. The rib is formed so that the operation handle 62 overlaps when the open lever 6 is in the standby position. Even when an article housed in the trunk room hits the operation handle 62, the operation handle 62 is supported in contact with the rib. Therefore, deformation is suppressed.

  In the manual release type latch device 2 described above, the open lever 6 rotates in the clockwise direction in FIG. 9 due to the urging force of the tension coil spring 63, but the driven portion 6 a 2 is attached to the stopper portion 81 provided in the case 8. Since it abuts, it always stops at the same position (standby position). Thereby, the manual release type latch device 2 described above does not require a separate stopper portion for stopping the open lever 6 at the standby position.

  Therefore, it is not necessary to cut and raise the stopper portion for stopping the open lever 6 at the standby position from the base plate 3. Thus, even if the open lever of the electric release type latch device 1 and the open lever of the manual release type latch device 2 are made into a common component, it is not necessary to avoid the space for disposing the worm wheel 74 and to lift it from the base plate 3. Therefore, as described above, the base plate 3 can be easily made into a common part. Further, in the electric release type latch device 1, the stopper portion 81 can be attached to the position where the cam 74a of the worm wheel 74 corresponding to the electric release type stop means is provided, so that the size of the device can be reduced. become.

  The electric release type latch device 1 and the manual release type latch device 2 described above are in contact with a driven portion 6a2 provided on the open lever 6 and manually release type stop means (case 8) for stopping the open lever 6 at the standby position. The stopper part 81) and the electric release type stop means (cam 74a of the worm wheel 74) are selectively attached to the base plate 3, so that it is not necessary to provide the base plate 3 with stop means. Thereby, the base plate 3 and the open lever 6 can be made into a common part, and the number of parts items to be managed and the part inventory can be reduced. Further, in both the electric release type latch device 1 and the manual release type latch device 2, a manual release type stop means and an electric release type stop means for holding the open lever 6 in the standby position are provided as a worm wheel. Since it can be provided within the rotation trajectory 74, the apparatus can be downsized.
