Retained.

  When the slide lever 14, the lock lever 15, the panic lever 16 and the lift lever 17 are in the unlocked position, that is, when the outside lock means is in the outside unlocked state, the release lever of the connect lever 24 is interlocked. When the panic lever 16 and the lift lever 17 move from the unlock position in the open direction, the release portion 171 of the lift lever 17 contacts the bent portion 101 of the open lever 10 from below. As a result, the open lever 10 is rotated in the release direction, and the ratchet 9 is disengaged from the latch 7, whereby the meshing between the latch 7 and the striker S is released and the door can be opened.

  When the slide lever 14, the lock lever 15, the panic lever 16, and the lift lever 17 are in the locked position, that is, when the outside lock means is in the outside lock state, the panic lever is interlocked with the release operation of the connect lever 24. 16 and the lift lever 17 move upward, the release portion 171 of the lift lever 17 is simply swung across the front of the bent portion 101 of the open lever 10, and the release operation of the connect lever 24 is performed by the open lever. 10 is not transmitted. Therefore, when the outside lock means is in the outside lock state, the door cannot be opened even if the outside handle is operated.

  The inside lock operation lever 22 is operated when the inside lock means is switched to the inside unlock state and the inside lock state by manual operation. The inside lock operation lever 22 is unlocked by a pivot 41 that faces the inside / outside of the vehicle above the connect lever 24 ( For example, see FIGS. 7 to 9) and the unlocked position pivotally supported at a locked position (see, for example, FIG. 6) pivoted by a predetermined angle in the clockwise direction in FIGS. The part is provided with a columnar manual operation part 221 that protrudes from the rotation surface to the vehicle inner side, and the lower part is provided with an elastically deformable tongue piece part 222 that extends downward along the rotation surface.

  By manually operating the manual operation unit 221 with the door opened, the inside lock operation lever 22 can be rotated to the unlock position and the lock position. The tongue piece 222 holds the inside lock operation lever 22 in the unlock position and the lock position by abutting with a protrusion 123 (see FIG. 3) protruding from the inner surface of the cover 12 with an elastic force. The manual operation unit 221 can be operated only in a state where the door protrudes from the end face of the door through the arc-shaped opening 124 (see FIGS. 3 and 4) provided in the cover 12.

  The inside lock actuating lever 23 is pivotally supported by a pivot 42 that faces inward and outward of the inside lock operation lever 22 and is unlocked (see, for example, FIGS. 7 to 9) and locked (see, for example, FIG. 6). And a contact portion 231 that can contact the tip 223 that is the upper portion of the inside lock operation lever 22 when in the locked position, and a cylindrical engagement / disengagement pin 44 with a hook And a long hole 232 that slidably engages in a direction, and is biased in an unlocking direction (for example, clockwise in FIG. 6) by a biasing force of a spring 43 disposed around the pivot 42.

  When the super lock lever 25 is in the unlock position (for example, see FIGS. 7 to 9), the inside lock operation lever 23 is unlocked by the urging force of the spring 43 when the inside lock operation lever 22 is in the unlock position. When the inside lock operation lever 22 is rotated from the unlock position to the lock position, the tip end portion 223 of the inside lock operation lever 22 comes into contact with the contact portion 231 of the inside operation lock lever 23 from the rear. By pushing the contact portion 231 forward, the spring 43 is rotated from the unlock position to the lock position against the urging force of the spring 43.

  When the inside lock operation lever 22 is in the locked position and the contact portion 231 of the inside lock operation lever 23 is in contact with the front end portion 223 of the inside lock operation lever 22, the direction of the force acting on the front end portion 223 is This is the direction toward the pivot 41 that is the center of rotation of the inside lock operation lever 22. Therefore, the inside lock operation lever 23 is held at the lock position against the urging force of the spring 43 without rotating the inside lock operation lever 22 toward the unlock position. When the inside lock operation lever 22 moves from the lock position to the unlock position, the tip 223 of the inside lock operation lever 22 is disengaged from the abutting portion 231 of the inside lock operation lever 23.

  In the state of FIG. 15, when the door is closed such as during parking, an unauthorized tool is illegally inserted from the gap between the door and the vehicle body, the manual operation portion 221 of the inside lock operation lever 22 is illegally operated, and the inside lock operation lever 22 is operated. Is moved from the lock position to the unlock position, the movement of the inside lock operation lever 22 is not transmitted to the inside lock operation lever 23, and the inside lock operation lever 23 is restrained to the lock position by the super lock lever 25. Therefore, the inside lock operation lever 23 does not move to the unlock position.

  Therefore, when the outside lock means is in the outside lock state, the inside lock means is in the inside lock state, and the super lock means is in the super lock state, the one-motion operation by the operation of the outside handle and the inside handle is disabled and the door Since not only blocking the opening but also switching to a state in which one-motion operation is possible is prevented, it is possible to reliably prevent the door from being opened by an unauthorized act.

  Further, even if the inside lock operation lever 22 is attacked with an improper tool and is forcibly displaced to the unlock position, the inside lock operation lever 22 is displaced in the unlock direction. 23, the inside lock operation lever 23 is not deformed. Therefore, even after such a situation occurs, the malfunction of the inside lock operation lever 23 does not occur. Therefore, if the inside lock operation lever 22 is moved to the unlock position, the inside lock operation lever 23 is moved to the unlock position. It can be displaced to enable a one-motion operation.

(When the outside handle or inside handle is operated when the door is closed and in the state shown in FIG. 10)

  When the outside handle is operated in the state of FIG. 10, the operation of the outside handle is transmitted to the outside lever 18 through the Bowden cable 34. The outside lever 18 performs a release operation against the urging force of the spring 35, and the operating portion 182 moves upward to push up the protrusion 241 of the connect lever 24 from below (clockwise in FIG. 10). Accordingly, the connect lever 24 is released (clockwise in FIG. 10), and the panic lever 16 and the lift lever 17 are moved from the unlock position to the open direction (upward). As a result, the release portion 171 of the lift lever 17 abuts against the bent portion 101 of the open lever 10 from below and pushes it up to rotate the open lever 10 in the release direction. As a result, the ratchet 9 rotates in the release direction and is disengaged from the latch 7, and the engagement between the latch 7 and the striker S is released, thereby enabling the door to be opened. At this time, the connect lever 24 is released by the release operation of the outside lever 18, but the release operation is not transmitted to the sub-inside lever 20. Thereby, unnecessary movement can be reduced and the opening of the door by the release operation of the outside lever 18 can be made smooth.

  When the inside handle is operated in the state of FIG. 10, the operation of the inside handle is transmitted to the inside lever 19 via the Bowden cable 36. The inside lever 19 is released against the urging force of the spring 38, and the side edge of the arm portion 192 contacts the engagement / disengagement pin 44. The engagement / disengagement pin 44 is pushed rearward (leftward in FIG. 10) and comes into contact with the side edge of the long groove 201 of the sub-inside lever 20 in accordance with the release operation of the inside lever 19, thereby releasing the inside lever 19. Is transmitted to the sub-inside lever 20, and the sub-inside lever 20 is also released.

  The release operation of the sub-inside lever 20 is performed by using the one-motion lever through the contact lever 202 of the sub-inside lever 20, the contacted portion 243 of the connect lever 24, and the arm lever 203 of the sub-inside lever 20. 21 respectively. As a result, the connect lever 24 is released in the same manner as when the outside lever 18 is released, and with this, the ratchet 9 can be rotated in the release direction to be released from the latch 7 to open the door. At this time, the connect lever 24 is released by the release operation of the inside lever 19 and the sub-inside lever 20, but the release operation is not transmitted to the outside lever 18. Thereby, unnecessary movement can be reduced and the opening of the door by the release operation of the inside lever 19 can be made smooth. Further, the one-motion lever 21 only rotates in the cancel direction (clockwise in FIG. 10) in conjunction with the release operation of the sub-inside lever 20, and the rotation is not transmitted to other elements.

  Therefore, in the state of FIG. 10, the door can be opened by operating either the outside handle or the inside handle.

(When the outside handle or inside handle is operated in the state of FIG. 11)

  When the outside handle is operated in the state of FIG. 11, the outside lever 18 is released against the urging force of the spring 35 and the operating portion 182 moves upward so that the protruding portion of the connect lever 24 is moved. The operation of the outside handle is transmitted to the connect lever 24 by pushing up 241 from below. Thereby, the connect lever 24 moves the panic lever 16 and the lift lever 17 in the opening direction (upward) from the lock position by performing a release operation. However, in this state, since the outside lock means is in the outside lock state, even if the lift lever 17 moves upward, the release portion 171 swings with respect to the bent portion 101 of the open lever 10. Due to the movement, the release operation of the outside lever 18 cannot be transmitted to the open lever 10. Therefore, the door cannot be opened. Also in this case, the release operation of the connect lever 24 due to the release operation of the outside lever 18 is not transmitted to the sub-inside lever 20.

  When the inside handle is operated in the state of FIG. 11, the release operation of the inside lever 19 is transmitted to the sub inside lever 20 via the engagement / disengagement pin 44 as described above, and the release operation of the sub inside lever 20 is performed. , Transmitted to the one-motion lever 21 and the connect lever 24. Also in this case, the release operation of the connect lever 24 due to the release operation of the inside lever 19 and the sub inside lever 20 is not transmitted to the outside lever 18.

  The release operation of the sub inside lever 20 is first transmitted to the one motion lever 21. Accordingly, the one motion lever 21 rotates in the cancel direction (clockwise in FIG. 11) against the urging force of the spring 46. As a result, as shown in FIG. 16, the upper end 211 comes into contact with the jaw 154 of the lock lever 15 in the locked position by the rotation of the one motion lever 21, and the lock lever 15 rotates toward the unlocked position. . When the lock lever 15, the panic lever 16, and the lift lever 17 move to a position immediately before the unlock position, the contact portion 202 of the sub inside lever 20 contacts the contacted portion 243 of the connect lever 24. Starts the release operation against the biasing force of the spring 39. Immediately after the connect lever 24 is released, the upper end 211 of the one-motion lever 21 is disengaged from the jaw 154 of the lock lever 23, and the lock lever 15 is displaced to the unlock position.

  Subsequently, as shown in FIG. 17, the panic lever 16 and the lift lever 17 that are displaced together with the lock lever 23 to the unlock position by the release operation of the connect lever 24 move from the unlock position to the open direction (upward), The release portion 171 of the lift lever 17 contacts the bent portion 101 of the open lever 10 from below to rotate the open lever 10 in the release direction. As a result, the ratchet 9 can be rotated in the release direction to disengage from the latch 7 and open the door.

  As described above, in the state shown in FIG. 11, the door cannot be opened by operating the outside handle. However, when the inside handle is operated, the outside locking means is switched from the outside locked state to the outside unlocked state. One-motion operation that can open the door is possible.

  In the state shown in FIG. 12, when the outside handle is operated, the outside lever 18 is released against the urging force of the spring 35, and the release operation is applied to the connect lever 24 via the operating portion 182. introduce. Accordingly, in conjunction with the release operation of the connect lever 24, the panic lever 16 and the lift lever 17 move from the unlock position to the open direction (upward), and the release portion 171 of the lift lever 17 bends the open lever 10. The open lever 10 is rotated in the release direction by coming into contact with the portion 101 from below. As a result, the ratchet 9 rotates in the release direction and is released from the latch 7 to allow the door to be opened. Also in this case, the release operation of the connect lever 24 due to the release operation of the outside lever 18 is not transmitted to the sub-inside lever 20.

  In the state shown in FIG. 12, when the inside handle is operated, even if the inside lever 19 is released against the urging force of the spring 38, the engagement / disengagement pin 44 moves the movement locus of the arm portion 192 of the inside lever 19. The release operation of the inside lever 19 is not transmitted to the sub inside lever 20 because it is located outside and cannot contact the arm portion 192. Therefore, the sub-inside lever 20 is maintained in a state where it is stopped at the standby position. Therefore, since the operation of the inside handle is transmitted only to the inside lever 19 and not to other operating elements, the outside locking means cannot be switched to the outside unlocked state, and the door can be opened. I can't open it.

  According to the above, in the state shown in FIG. 12, the outside lock means is in the outside unlocked state, so it is possible to open the door by operating the outside handle, but the inside lock means is in the inside locked state. Even if the inside handle is operated, the door cannot be opened even if the outside lock means is in the outside unlocked state.

(When the outside handle or inside handle is operated when the door is closed and in the state shown in FIG. 13)

  In the state of FIG. 13, when the outside handle is operated, the outside lock means is in the outside lock state. Therefore, even if the connect lever 24 is released along with the release operation of the outside lever 18, Thus, the panic lever 16 and the lift lever 17 simply move in the open direction from the lock position, and cannot open the open lever 10 in the release direction. Therefore, the door cannot be opened even if the outside handle is operated.

  In the state shown in FIG. 13, when the inside handle is operated, the inside lock means is in the inside lock state. Therefore, even if the inside lever 19 is released against the urging force of the spring 38, the release operation is not performed. , It is not transmitted to the sub-inside lever 20. Therefore, the outside lock means cannot be switched to the outside unlocked state, and the door cannot be opened.

(When the outside handle or inside handle is operated when the door is closed and in the state shown in FIG. 14)

  In the state of FIG. 14, when the outside handle is operated, the outside locking means is in the outside unlocked state, and the release operation of the outside lever 18 is transmitted to the open lever 10. Can be opened.

  In the state of FIG. 14, when the inside handle is operated, the inside lock means is in the inside lock state, and the release operation of the inside lever 19 cannot be transmitted to the sub-inside lever 20, so that the door cannot be opened. Can not.

  As described above, in the state shown in FIG. 14, the door can be opened by operating the outside handle, but the door cannot be opened by operating the inside handle.

(When the outside handle or inside handle is operated when the door is closed and in the state shown in FIG. 15)

  In the state of FIG. 15, both the outside lock means and the inside lock means are in the locked state, and therefore the door cannot be opened by operating either the outside handle or the inside handle. Furthermore, since it is also in the super-lock state as described above, the inside lock means cannot be switched to the inside unlock state even if the inside lock operation lever 22 is moved to the unlock position.

(When the door is closed and in the state shown in FIG. 11, the unlocking / unlocking operation switch is unlocked immediately after the outside handle or inside handle is operated)

  11, the panic lever 16 and the lift lever 17 are moved forward of the open lever 10 from the locked position in conjunction with the release operation of the connect lever 24 by operating the outside handle or the inside handle, as shown in FIG. When the locking / unlocking operation switch is unlocked in a state of moving in the open direction across the lock lever 15, the lock lever 15 rotates in the unlocking direction from the locked position by driving the locking / unlocking motor 26. The panic lever 16 and the lift lever 17 that are moved in the opening direction by the rotation also try to move in the unlocking direction. However, when the lift lever 17 that is moving in the open direction moves toward the unlocking direction, as shown in FIG. 20, before the lift lever 17 completely moves to the unlocked position, the lift lever 17 The rear side surface of the release portion 171 collides with the front end of the bent portion 101 of the open lever 10 from the front, and a state where further movement of the lift lever 17 is prevented, that is, a panic state occurs. However, even if a panic condition occurs, the lift lever 17 is connected to the lock lever 15 via the spring 40 and the panic lever 16, so that even if the movement of the lift lever 17 toward the lock position is prevented, the lift lever 17 is locked. The lever 15 moves to the unlock position together with the panic lever 16 against the biasing force of the spring 40.

  Next, when the operation of the outside handle or the inside handle is interrupted from the state shown in FIG. 20, with the return of the outside lever 18 or the inside lever 20 to the standby position, the connect lever 24 returns to the original position and the lift lever 17 and the panic lever 16 move downward, and the rear side surface of the release portion 171 of the lift lever 17 is disengaged from the front end of the bent portion 101 of the open lever 10, and as shown in FIG. The urging force of 40 moves to the unlock position.

  As described above, even if a panic occurs, the lock lever 15 can be moved to the unlock position, and the lift lever 17 interrupts the operation of the outside handle or the inside handle, thereby Can be moved to the unlock position. Therefore, even if a panic state occurs, the outside lock means can be reliably switched to the outside unlock state.
