  A shaft portion 29 b provided at the lower end portion of the engagement / disengagement lever 29 is rotatably connected to the front end portion of the lock lever 18. When the lock lever 18 is in the unlocked position, the engagement / disengagement lever 29 has an engagement portion 29a engaged with the elongated hole 15a of the second fully-closed release lever 15 so as to be slidable in the vertical direction, particularly in FIG. As is clearly shown in FIG. 4, the engaging groove 14b of the first fully closing release lever 14 is engaged.

  As described above, when the lock lever 18 is in the unlocked position, the rotation of the first fully-closed release lever 14 is released through the engagement groove 14 b and the engagement portion 29 a of the engagement / disengagement lever 29. It is transmitted to the lever 15. When the lock lever 18 is in the unlocked position, the center of the shaft portion 29 b of the engagement / disengagement lever 29 is set to coincide with the center of the first support shaft 24.

  Although not shown, when the lock lever 18 is in the locked position, the engaging portion 29a of the engagement / disengagement lever 29 moves upward and disengages from the engagement groove 14b of the first fully-closed release lever 14. To do. Thereby, the rotation of the first fully closed release lever 14 is not transmitted to the second fully closed release lever 15.

  The first fully opened release lever 19 is pivotally supported on the other side surface of the base member 7 by the first support shaft 24 and is urged and held by a spring 37 to a standby position (see FIGS. 4, 6 and 9). When 5 is operated or the inside handle 6 is closed, it rotates in the opening direction (clockwise in FIG. 4) against the urging force of the spring 37 from the standby position to move to the operating position (FIG. 7). , 8, 10).

  A long hole 19b in the front-rear direction is provided in the front portion of the first fully opened release lever 19, and the lower end portion of the first link 26 is connected to the connecting shaft 35 in the arm portion 19a similarly provided below the long hole 19b. It is connected via.

  The cam portion 19c around which the cable 20 connected to the second fully open release lever 21 is wound is formed on the outer peripheral surface forming the contour of the lower part away from the rotation center (first support shaft 24) in the first fully open release lever 19. And an arc portion 19d are provided continuously. The cam portion 19c and the arc portion 19d will be described in detail later.

  The second fully opened release lever 21 is pivotally supported by the second support shaft 25 on the other side surface of the base member 7, is in a region between the first support shaft 24 and the second support shaft 25, and is second A terminal portion 20 a of the cable 20 is connected to a portion that moves in the vertical direction as the fully open release lever 21 rotates. Further, the rear end portion of the second fully open release lever 21 is connected to the long hole 19b of the first fully open release lever 19 via a connecting shaft 36 that faces the inside and outside of the vehicle.

  The base member 7 is fixed so that one end portion of the flexible conduit 38 through which the cable 20 is slidably inserted in the front-rear direction (axial direction) faces the front-rear direction at the lower rear side of the first support shaft 24. Is done. It should be noted that the substantially rear half of the conduit 38 is bent so as to face downward.

  In the cable 20, the terminal portion 20 a is connected to the rear end portion of the second fully open release lever 21, and the cam portion 19 c of the first fully open release lever 19 is on the way from the terminal portion 20 a to the portion inserted into the conduit 38. And it is wound by the circular arc part 19d, is extended back, and is penetrated in the conduit | pipe 38. FIG. Thereby, the up-down direction movement area | region part 20b (refer FIGS. 9-11) between the terminal part 20a in the cable 20 and the winding area | region part 20d (refer FIGS. 9-11) wound by the cam part 19c is obtained. As the second fully open release lever 21 rotates, it moves up and down. In addition, the front-rear direction moving region 20 c, which is a region between the winding region 20 d of the cable 20 and the portion immediately before being inserted into the conduit 38, moves in the front-rear direction as the second fully open release lever 21 rotates. Moving.

  As clearly shown in FIGS. 9 to 11, the cam portion 19 c is an outer peripheral portion of the first fully opened release lever 19 away from the first support shaft 24, more specifically, below the first support shaft 24. In addition, it is provided in a range T1 between the starting point A at the beginning of formation of the cam portion 19c and the end point B at the end of formation of the cam portion 19c, and goes from the starting point A to the end point B (opposite to the releasing direction of the first fully open releasing lever 19) The distance r1 from the first support shaft 24 is formed so as to increase gradually according to the direction). Further, the end point B of the cam portion 19c is such that the tangential direction of the end point B and the axial direction X of the longitudinal movement region portion 20c of the cable 20 when the first fully open release lever 19 is in the standby position as shown in FIG.

  As described above, when the first fully opened release lever 19 and the second fully opened release bar 21 are both turned from the standby position shown in FIG. 9 to the release (operation) direction and turned to the operation position shown in FIG. The winding region 20d of the cable 20 being wound is displaced forward, that is, in the pulling direction parallel to the axial direction X of the conduit 38. Accordingly, the pulling stroke in which the cable 20 is pulled out from the conduit 38 when the second fully opened release lever 21 rotates is operated from the standby position (the position indicated by the solid line) of the second fully opened release lever 21 as shown in FIG. The first fully open release lever 19 is moved from the standby position (the position indicated by the solid line) to the operating position (the two-dot chain line) at a distance L1 in which the terminal portion 20a has moved upward along with the rotation to the position (the position indicated by the two-dot chain line). Is approximately equal to the distance obtained by adding the distance L2 in which the winding area 20d of the cable 20 is displaced forward, that is, the distance L2 in which the vertical movement area 20b of the cable 20 is displaced forward. Equivalent to. Accordingly, the cable when the second fully open release lever 21 is rotated from the standby position to the operating position without increasing the amount of rotation of the second fully open release lever 21 or increasing the arm length of the second fully open release lever 21. Twenty traction strokes can be amplified.

  The arc portion 19d is continuous with the end point B of the cam portion 19c, and has an arc shape centering on the first support shaft 24 within a predetermined angle range T2 from the end point B to the side opposite to the operating direction of the first fully open release lever 19. Formed. Thus, as shown in FIG. 9, when the first fully open release lever 19 is in the standby position, the cable 20 is not wound around the arc portion 19d, but the first fully open release lever 19 is moved from the standby position. As shown in FIG. 10, the longitudinal movement area 20c of the cable 20 is gradually wound around the arc portion 19d as it rotates to the operating position. As a result, even if the first fully open release lever 19 is rotated from the standby position to the operating position, the axial direction X of the longitudinal movement area 20c of the cable 20 does not change, and therefore the cable 20 is pulled smoothly. be able to.

Next, the operation of the embodiment according to the present invention will be described.
As shown in FIG. 6, when the lock lever 18 and the child proof lever 22 are respectively in the unlocked position, when the outside handle 5 is operated from the outside of the vehicle, the outside lever 11 is moved from the standby position shown in FIG. , The rotation is transmitted to the second fully-closed release lever 15 via the first fully-closed release lever 14 and the engagement / release lever 29.

  The second fully-closed release lever 15 is rotated to the operating position shown in FIG. 7 to transmit the operation of the outside handle 5 to the fully-closed door latch device 2 via the cable 23. Accordingly, when the door 1 is in the fully closed position, the door 1 can be opened by releasing the fully closing door latch device 2.

  Further, the operation of the outside handle 5 is transmitted to the fully-closed door latch device 2, and at the same time, the second fully-open release is made via the contact portion 11 c of the outside lever 11, the first fully-open release lever 19 and the connecting shaft 36. It is also transmitted to the lever 21. As a result, the first fully opened release lever 19 and the second fully opened release lever 21 rotate from the standby position shown in FIG. 6 to the operating position shown in FIG.

  When the inside handle 6 is closed from the inside of the vehicle, the first inside lever 12 rotates from the standby position shown in FIG. 6 to the operating position shown in FIG. Accordingly, the rotation is transmitted to the second fully open release lever 21 via the engagement pin 26 a, the first link 26, the connecting shaft 35, the first fully open releasing lever 19, and the connecting shaft 36. As a result, the first fully opened release lever 19 and the second fully opened release lever 21 rotate from the standby position shown in FIG. 6 to the operating position shown in FIG.

  When the first fully opened release lever 19 and the second fully opened release lever 21 are both turned to the operating position, the cable 20 has a distance L1 in which the terminal portion 20a is moved upward by the turning of the second fully opened release lever 21 as described above. The vertical movement region 20b is pulled by a towing stroke substantially corresponding to the distance obtained by adding the distance L2 moved forward. As a result, the fully open door latch device 3 can be released to close the door 1.

  As described above, in the present embodiment, the cam portion 19c around which the cable 20 is wound is provided on the first fully open release lever 19, thereby increasing the amount of rotation of the second fully open release lever 21 or the second fully open release lever. The relay operating device 4 can be miniaturized because the pulling stroke of the cable 20 when the second fully opened release lever 21 is rotated from the standby position to the operating position can be amplified without increasing the arm length of the relay 21. be able to. Moreover, the cable 20 can be smoothly pulled by having formed the circular arc part 19d continuously in the cam part 19c.

  FIG. 12 shows another embodiment of the present invention. In this embodiment, the second fully open release lever 21 is eliminated, and the terminal portion 20a of the cable 20 is changed from the standby position indicated by the solid line to the operating position indicated by the two-dot chain line based on the operation of the outside handle 5 and the inside handle 6. It is connected to a fully open release lever 40 that rotates. The cable 20 is wound around a cam portion 40a and a circular arc portion 40b having the same shape as that of the above-described embodiment provided on the fully open release lever 40.

  When the fully open release lever 40 is rotated from the standby position to the operating position based on the operation of the outside handle 5 or the inside handle 6, the winding region portion 20d of the cable 20 wound around the cam portion 40a is moved forward, that is, It is displaced in the pulling direction parallel to the axial direction X of the conduit 38. As a result, the pulling stroke in which the cable 20 is pulled out from the conduit 38 is such that the fully open release lever 40 operates from the standby position at a distance L3 that the terminal portion 20a moves when the fully open release lever 40 rotates from the standby position to the operating position. The distance approximately corresponds to a distance obtained by adding a distance L4 in which the winding region 20d of the cable 20 is displaced forward with the rotation to the position. Therefore, also in this embodiment, the pulling stroke of the cable 20 can be amplified without increasing the amount of rotation of the fully open release lever 40 or increasing the arm length of the fully open release lever 40.

Although the embodiment of the present invention has been described above, the following various modifications and changes can be made to the present embodiment without departing from the gist of the present invention.
