Since the leaf spring 40 is elastically deformed by bringing the opening cam surface 26 and the arcuate surface 27 of the inside rotation lever 24 into contact with the bent portion 41 in this way, when the inside handle 211 is rotated in the opening direction, Compared with the case where the handle 211 is rotated in the closing direction, the load on the leaf spring 40 is small.

  The limit switch 36 is electrically connected to the PSD motor M1, and the PSD motor M1 is electrically connected to an ECU (Electronic Control Unit, not shown) which is a known control means provided in the vehicle body 200. ing. Furthermore, this ECU is electrically connected to a courtesy switch (not shown) provided on the vehicle body 200 for detecting the open / closed state of the slide door 204. When the limit switch 36 is turned on when the courtesy switch is OFF (that is, when the slide door 204 is in the fully closed state), the PSD motor M1 rotates in the direction to open the slide door 204, and the courtesy switch is When turned on (that is, when the slide door 204 is fully opened), the PSD motor M1 stops rotating. On the other hand, when the courtesy switch is ON (that is, when the slide door 204 is fully open), when the limit switch 36 is turned ON, the PSD motor M1 rotates in a direction to close the slide door 204 and the courtesy switch is OFF. (Ie, when the slide door 204 is fully closed), the PSD motor M1 stops rotating. When the limit switch 36 is turned on again by re-operating the inside handle 211 while the slide door 204 is being slid, the PSD motor M1 is reversed and the slide door 204 is slid in a direction opposite to the sliding direction.

A tension spring S2 is provided between the outside rotation lever 43 and the fixed support plate 20, and the outside rotation lever 43 is shown in FIGS. 4 and 12 by the urging force (tensile force) of the tension spring S2. It is biased toward the initial position (non-operation position) shown. Therefore, when the outside handle 210 and the door opening / closing switch are not operated, the outside side rotation lever 43 is held at the initial position.
When the outside handle 210 is rotated (opened) outside the vehicle, this movement is transmitted to the outside side rotation lever 43 via the link member L1, and the outside side rotation lever 43 is viewed from the initial position in FIGS. 4 and 12 in the clockwise direction, and rotate to the open / close position shown in FIG. While the outside rotation lever 43 rotates from the initial position to the opening / closing position, the opening / closing cam surface 46 gradually elastically deforms the leaf spring 40 upward, so that the leaf spring 40 pushes the pressed pin 39 upward, When the outside side rotation lever 43 reaches the open / close position, the pressed pin 39 is pushed in and the limit switch 36 is turned on. When the door opening / closing switch is pressed, the electric motor M2 is rotated, and the output rotating member M2a is rotated in the clockwise direction in FIG. Then, this power is transmitted to the outside rotation lever 43 through the link member L2 and the slide member 49, and the outside rotation lever 43 rotates to the open / close position, so that the limit switch 36 is turned on.
When the outside handle 210 or the door opening / closing switch is operated in this way, the limit switch 36 is turned on. Therefore, if the outside handle 210 or the door opening / closing switch is operated when the sliding door 204 is in the fully closed state, the ECU The motor M1 is rotated in the opening direction. On the other hand, if the outside handle 210 or the door opening / closing switch is operated when the slide door 204 is in the fully open state, the ECU rotates the PSD motor M1 in the closing direction.

  FIG. 15 is a side view when the inside handle 211 is rotated to the open position in the state of FIG. 14 (the outside handle 210 is the initial position). At this time, since the inside rotation lever 24 rotates to the open position, the upper end of the guide slot L3a presses the pivot pin 53 downward, and as a result, the inside linkage plate 60 rotates counterclockwise in FIG. The inside linkage plate 60 rotates to the open position shown in FIG. Then, since the engaging pin 93 rotates counterclockwise together with the transferable portion 63, the slide member 90 and the switching plate 80 rotate counterclockwise together. Further, when the switching plate 80 rotates counterclockwise, the idle swing portion 87 of the switching plate 80 rotates relative to the engagement pin 109 (i.e., idle), so that the slide member 106 does not move and the switching plate 80 rotates. It is not transmitted to the open plate 70. Therefore, the lock device 208 and the lock device 209 linked to the open plate 70 maintain the locked state. Further, at this time, the limit switch 36 is turned ON by the arc surface 27 of the inside rotation lever 24, but the ECU does not rotate the PSD motor M1 because the ECU detects that the slide door 204 is not unlocked.

  FIG. 16 is a side view when the outside handle 210 is rotated in the opening direction in the state of FIG. 14 (the inside handle 211 is in the initial position). At this time, the outside side rotation lever 43 rotates in the clockwise direction of FIG. 14 against the biasing force of the tension spring S2, and the pressing portion 48 presses (rotates) the pressed portion 84, so that the switching plate 80 is It rotates counterclockwise in FIG. 14 around the pivot pin 55. However, since the idling portion 87 of the switching plate 80 rotates relative to the engagement pin 109 (idling), the slide member 106 does not move and the rotation of the switching plate 80 is not transmitted to the open plate 70. Therefore, the lock device 208 and the lock device 209 linked to the open plate 70 maintain the locked state. Further, at this time, the limit switch 36 is turned on by the opening / closing cam surface 46 of the outside rotation lever 43, but the ECU detects that the sliding door 204 is not unlocked, so the ECU turns off the PSD motor M1. Do not rotate.

(2: When the slide door 204 is fully closed, the child proof lever 97 is in the ON position (valid), and the lock knob 102 is in the lock position)
FIG. 17 shows the main part of the lock control mechanism 10 when the child proof lever 97 is in the ON position, the lock knob 102 is in the lock position, and the outside handle 210 and the inside handle 211 are in the initial position (non-operation position). It is the side view seen from the outside. At this time, the inside side rotation lever 24, the outside side rotation lever 43, the inside linkage plate 60, the open plate 70, and the switching plate 80 are all in the initial position (non-operation position). Further, the slide member 90 is fitted to the upper end portion of the long hole portion 82, and the engagement pin 93 is fitted to the front end portion of the idle swing portion 64 (the upper end portion of the transmittable portion 63). Further, the slide member 106 is fitted to the rear end portion (left end portion of FIG. 17) of the guide hole 71 as in FIG. 14, and the engagement pin 108 is located at the rear end portion of the horizontal portion 57. The engagement pin 109 is fitted to the upper end portion of the idle swing portion 87. Further, although not shown, the locking device 208 and the locking device 209 are in a locked state, and lock the front and rear strikers 206 and strikers 207, respectively.

  FIG. 18 is a side view when the inside handle 211 is rotated to the open position in the state of FIG. 17 (the outside handle 210 is the initial position). At this time, since the inside rotation lever 24 rotates to the open position, the upper end of the guide slot L3a presses the pivot pin 53 downward, and as a result, the inside linkage plate 60 rotates counterclockwise, and the inside linkage plate 60 rotates to the open position shown in FIG. Then, the idling portion 64 of the inside linkage plate 60 rotates relative to the engagement pin 93 (the idling portion 64 is idly swung with respect to the engagement pin 93), so that the rotational force of the inside linkage plate 60 is applied to the switching plate 80. Not transmitted. Therefore, since the open plate 70 does not rotate (since the open plate 70 is not directly linked to the inside linkage plate 60), the lock device 208 and the lock device 209 linked to the open plate 70 maintain the locked state. Further, at this time, the limit switch 36 is turned ON by the arc surface 27 of the inside rotation lever 24, but the ECU does not rotate the PSD motor M1 because the ECU detects that the slide door 204 is not unlocked.

  FIG. 19 is a side view when the outside handle 210 is rotated in the opening direction in the state of FIG. 17 (the inside handle 211 is in the initial position). At this time, the outside side rotation lever 43 rotates in the clockwise direction in FIG. 17 against the biasing force of the tension spring S2, and the pressing portion 48 presses (rotates) the pressed portion 84, so that the switching plate 80 is It rotates counterclockwise in FIG. 17 around the pivot pin 55. However, since the idling portion 87 of the switching plate 80 rotates relative to the engaging pin 109 (idling), the slide member 106 does not move and the rotation of the switching plate 80 is not transmitted to the open plate 70. Therefore, the lock device 208 and the lock device 209 linked to the open plate 70 maintain the locked state. Further, at this time, the limit switch 36 is turned on by the opening / closing cam surface 46 of the outside rotation lever 43, but the ECU detects that the sliding door 204 is not unlocked, so the ECU turns off the PSD motor M1. Do not rotate.

(3: When the slide door 204 is fully closed, the child proof lever 97 is in the OFF position (invalid), and the lock knob 102 is in the unlock position)
FIG. 20 shows the main part of the lock control mechanism 10 when the child proof lever 97 is in the OFF position, the lock knob 102 is in the unlock position, and the outside handle 210 and the inside handle 211 are in the initial position (non-operation position).

  FIG. 21 is a side view when the inside handle 211 is rotated to the open position in the state of FIG. 20 (the outside handle 210 is the initial position). At this time, since the inside rotation lever 24 rotates to the open position, the upper end of the guide slot L3a presses the pivot pin 53 downward, and as a result, the inside linkage plate 60 rotates counterclockwise in FIG. The inside linkage plate 60 rotates to the open position shown in FIG. Then, since the engaging pin 93 rotates in the counterclockwise direction of FIG. 20 together with the transferable portion 63, the slide member 90 and the switching plate 80 rotate in the counterclockwise direction together. Further, when the switching plate 80 rotates counterclockwise, the engaging pin 109 rotates together with the transferable portion 86 of the switching plate 80, and the slide member 106 together with the open plate 70 (guide hole 71) is shown. Rotate 20 counterclockwise. Accordingly, the lock device 208 and the lock device 209 linked to the open plate 70 change from the locked state to the unlocked state, and the slide door 204 can slide in the opening direction. Further, at this time, the limit switch 36 is turned on by the circular arc surface 27 of the inside rotation lever 24, and the ECU detects that the lock device 208 and the lock device 209 are changed from the locked state to the unlocked state. Rotates the PSD motor M1 in the opening direction. Accordingly, when the slide door 204 slides in the opening direction and the courtesy switch detects that the slide door 204 has reached the fully open position, the ECU stops the PSD motor M1.

  FIG. 22 is a side view when the outside handle 210 is rotated in the opening direction in the state of FIG. 20 (the inside handle 211 is in the initial position). At this time, the outside side rotation lever 43 rotates in the clockwise direction of FIG. 20 against the biasing force of the tension spring S2, and the pressing portion 48 presses (rotates) the pressed portion 84, so that the switching plate 80 is It rotates counterclockwise around the pivot pin 55. Then, the engaging pin 109 rotates together with the transferable portion 86 of the switching plate 80, and further, the slide member 106 rotates counterclockwise in FIG. 20 together with the open plate 70 (guide hole 71). Accordingly, the lock device 208 and the lock device 209 linked to the open plate 70 change from the locked state to the unlocked state, and the slide door 204 can slide in the opening direction. Further, at this time, the limit switch 36 is turned ON by the opening / closing cam surface 46 of the outside rotation lever 43, and the ECU detects that the lock device 208 and the lock device 209 are changed from the locked state to the unlocked state. Therefore, the ECU rotates the PSD motor M1 in the opening direction. Accordingly, when the slide door 204 slides in the opening direction and the courtesy switch detects that the slide door 204 has reached the fully open position, the ECU stops the PSD motor M1.

(4: When the sliding door 204 is fully closed, the child proof lever 97 is in the ON position (valid), and the lock knob 102 is in the unlock position)
FIG. 23 shows the main part of the lock control mechanism 10 when the child proof lever 97 is in the ON position, the lock knob 102 is in the unlock position, and the outside handle 210 and the inside handle 211 are in the initial position (non-operation position). It is the side view seen from the vehicle outer side. At this time, the inside side rotation lever 24, the outside side rotation lever 43, the inside linkage plate 60, the open plate 70, and the switching plate 80 are all in the initial position (non-operation position). The slide member 90 is fitted to the upper end portion of the long hole portion 82, and the engagement pin 93 is fitted to the front end portion of the idle swing portion 64 (the upper end portion of the transmittable portion 63). Further, the slide member 106 is fitted to the rear end portion of the guide hole 71 (the right end portion in FIG. 20; however, located behind the square hole portion 73 (leftward in FIG. 20)). The pin 108 is positioned at the lower end portion of the arc portion 58 (the front end portion of the horizontal portion 57; the right end portion in FIG. 20), and the engagement pin 109 is fitted to the front end portion (the right end portion in FIG. 20) of the transmittable portion 86. Match. Further, although not shown, the locking device 208 and the locking device 209 are in a locked state, and lock the front and rear strikers 206 and strikers 207, respectively.

  FIG. 24 is a side view when the inside handle 211 is rotated to the open position in the state of FIG. 23 (the outside handle 210 is the initial position). At this time, since the inside rotation lever 24 rotates to the open position, the upper end of the guide slot L3a presses the pivot pin 53 downward, and as a result, the inside linkage plate 60 rotates counterclockwise, and the inside linkage plate 60 rotates to the open position shown in FIG. Then, the idling part 64 rotates relative to the engaging pin 93 (the idling part 64 idly swings with respect to the engaging pin 93), so that the rotational force of the inside linkage plate 60 is not transmitted to the switching plate 80. Therefore, since the open plate 70 does not rotate (since the open plate 70 is not directly linked to the inside linkage plate 60), the lock device 208 and the lock device 209 linked to the open plate 70 maintain the locked state. Further, at this time, the limit switch 36 is turned ON by the arc surface 27 of the inside rotation lever 24, but the ECU does not rotate the PSD motor M1 because the ECU detects that the slide door 204 is not unlocked.

  FIG. 25 is a side view when the outside handle 210 is rotated in the opening direction in the state of FIG. 23 (the inside handle 211 is in the initial position). At this time, the outside side rotation lever 43 rotates in the clockwise direction in FIG. 25 against the urging force of the tension spring S2, and the pressing portion 48 presses (rotates urging) the pressed portion 84. It rotates counterclockwise around the pivot pin 55. Then, the engagement pin 109 rotates together with the transferable portion 86 of the switching plate 80, and the slide member 106 rotates counterclockwise in FIG. 23 together with the open plate 70 (guide hole 71). Accordingly, the lock device 208 and the lock device 209 linked to the open plate 70 change from the locked state to the unlocked state, and the slide door 204 can slide in the opening direction. Further, at this time, the limit switch 36 is turned ON by the opening / closing cam surface 46 of the outside rotation lever 43, and the ECU detects that the lock device 208 and the lock device 209 are changed from the locked state to the unlocked state. Therefore, the ECU rotates the PSD motor M1 in the opening direction. Accordingly, when the slide door 204 slides in the opening direction and the courtesy switch detects that the slide door 204 has reached the fully open position, the ECU stops the PSD motor M1.

Next, a procedure for unlocking the door by operating the door opening / closing switch provided on the front panel of the driver's seat instead of operating the outside handle 210 will be described.
When the door opening / closing switch is turned on in the state of FIG. 20 (the lock knob 102 is in the unlocked position, the child proof lever 97 is in the OFF position, and the door opening / closing switch is OFF (non-operational)), the electric motor M2 is Starting, M2a rotates clockwise in FIG. Then, since the slide member 49 connected to the upper end portion of the link member L2 presses the lower end portion of the guide slot 47 downward, the outside side rotation lever 43 rotates clockwise in FIG. The lever 43 rotates to the open / close position shown in FIG. Then, as shown in FIG. 27, the pressing portion 48 presses (presses and rotates) the pressed portion 84, so that the switching plate 80 rotates counterclockwise around the pivot pin 55. As a result, since the open plate 70 rotates as in the case of FIG. 22, the lock device 208 and the lock device 209 change from the locked state to the unlocked state, and the slide door 204 can slide in the opening direction. Further, at this time, the limit switch 36 is turned ON by the opening / closing cam surface 46 of the outside rotation lever 43, and the ECU detects that the lock device 208 and the lock device 209 are changed from the locked state to the unlocked state. Therefore, the ECU rotates the PSD motor M1 in the opening direction. Accordingly, when the slide door 204 slides in the opening direction and the courtesy switch detects that the slide door 204 has reached the fully open position, the ECU stops the PSD motor M1.
FIG. 26 illustrates an example in which the child proof lever 97 is in the OFF position. However, since the child proof lever 97 is irrelevant to the movement of the door opening / closing switch, even if the child proof lever 97 is in the ON position. If the door opening / closing switch is operated, the lock device 208 and the lock device 209 change from the locked state to the unlocked state in the same manner as described above.

Next, the procedure for moving the lock knob 102 to the lock position by operating the lock release switch provided on the front panel of the driver's seat instead of operating the lock knob 102 will be described.
FIG. 4 shows the main part of the lock control mechanism 10 when the child proof lever 97 is in the OFF position, the lock knob 102 is in the unlock position, and the outside handle 210 and the inside handle 211 are in the initial position (non-operation position). It is the side view seen from the outside. At this time, the inside side rotation lever 24, the outside side rotation lever 43, the inside linkage plate 60, the open plate 70, and the switching plate 80 are all in the initial position (non-operation position). When the lock release switch is turned on in this state, the electric motor M3 is started and the rotating lever 117 is rotated clockwise in FIG. 4 to move to the position in FIG. Then, the lock switching lever 113 whose engagement pin 115 is engaged with the engagement long hole 118 of the rotation lever 117 rotates counterclockwise around the pivot pin 112. Accordingly, the engagement pin 108 of the slide member 106 engaged with the arc hole 114 of the lock switching lever 113 moves rearward, and the engagement pin 108 located at the lower end portion of the arc portion 58 (the front end portion of the horizontal portion 57). The mating pin 108 moves to the rear end portion of the horizontal portion 57. Further, the engagement pin 109 fitted to the front end portion of the transferable portion 86 moves to the upper end portion of the idle swing portion 87.

(5: When the sliding door 204 in the fully open position is closed to the fully closed position)
Finally, the case where the slide door 204 in the fully open position is closed to the fully closed position will be described.
The state shown in FIG. 20 (the lock knob 102 is in the unlocked position, the child proof lever 97 is in the OFF position, the outside handle 210 and the inside handle 211 are in the initial position (non-operating position), the inside rotation lever 24, the out When the inside handle 211 is rotated in the closing direction when the side rotation lever 43, the inside linkage plate 60, the open plate 70, and the switching plate 80 are all in the initial position (non-operation position), the inside rotation lever 24 is operated. Rotates around the rotation shaft 212 (tip portion 216) in the clockwise direction in FIG. 20, and the inside rotation lever 24 rotates to the closed position shown in FIG. Then, since the link member L3 is pulled upward, the upper edge portion of the guide long hole L3a engaged with the pivot pin 53 is separated upward from the pivot pin 53. That is, since the guide long hole L3a is swung with respect to the pivot pin 53, the moving force of the link member L3 is not transmitted to the inside linkage plate 60 (and also to the open plate 70 and the switching plate 80).
Simultaneously with this movement, the closing cam surface 28 of the inside rotation lever 24 pushes the pressed pin 39 upward, and the limit switch 36 is turned on. Then, since the courtesy switch detects that the slide door 204 is in the fully open position, the ECU rotates the PSD motor M1 in the closing direction, and the slide door 204 slides to the fully closed position. Further, when the slide door 204 reaches the fully closed position and is detected by the courtesy switch, the ECU stops the PSD motor M1, and the lock device 208 and the lock device 209 lock the striker 206 and the striker 207, respectively.
On the other hand, when the door opening / closing switch is turned ON in the state of FIG. 20, the outside rotation lever 43 is rotated to the opening / closing position by the power of M2 as described above, and the opening / closing cam surface 46 of the outside rotation lever 43 is moved. The limit switch 36 is turned on. Then, since the courtesy switch detects that the slide door 204 is in the fully open position, the ECU rotates the PSD motor M1 in the closing direction. Further, when the courtesy switch detects that the slide door 204 has reached the fully closed position, the ECU stops the PSD motor M1, and the lock device 208 and the lock device 209 lock the striker 206 and the striker 207, respectively.

  If the clutch that switches the function of the power transmission mechanism for transmitting the power of the PSD motor M1 to the slide door 204 between the valid state and the invalid state is disconnected by operating a changeover switch provided in the vehicle, the slide door 204 can be manually opened and closed.

As described above, in the present embodiment, the inside handle 211 and the inside rotation lever 24 are connected by the rotation shaft 212 so as to be coaxial and relatively non-rotatable, so that the rotation of the inside handle 211 is directly directed to the inside rotation lever 24. Is transmitted to. Therefore, the operation of the inside handle 211 is rotated inward compared to the case where the inside handle 211 and another mechanism that operates independently of the inside rotation lever 24 are interposed between the inside handle 211 and the inside rotation lever 24. Transmission to the lever 24 can be ensured. Accordingly, it is possible to reliably perform the ON / OFF switching of the limit switch 36 by the inside rotation lever 24.
Furthermore, since the structure for rotating the inside rotation lever 24 by the inside handle 211 is very simple, the mechanism of this part can be obtained at a lower manufacturing cost than the conventional apparatus.

Further, since the opening cam surface 26, the circular arc surface 27, and the closing cam surface 28 are formed on the inside rotation lever 24, even if the inside handle 211 is rotated in either the clockwise direction or the counterclockwise direction, It is possible to switch the limit switch 36 on and off.
In addition, by a simple mechanism including the torsion coil spring S1, the engagement recess 30, the engagement recess 31, the guide hole 33, and the guide hole 34, the inside rotation lever 24 is set to the initial position when the inside handle 211 is not operated. It is possible to hold.

In this embodiment, the electric motor M3 is rotated by the operation of the lock release switch. However, it is of course possible to rotate the electric motor M3 by a remote control operation (keyless operation) from the outside of the vehicle.
Further, when the inside handle 211 is rotated in the opening direction, the opening cam surface 26 and the arcuate surface 27 are brought into contact with the bent portion 41 to elastically deform the leaf spring 40, but the closing cam surface 28 is viewed in a side view. The cam surface gradually increases as the linear distance from the central axis (rotation center) of the rotation shaft 212 increases in the counterclockwise direction (when viewed from the outside of the vehicle), and this closing is performed when the inside handle 211 rotates in the closing direction. The plate spring 40 may be elastically deformed by bringing the cam surface 28 into contact with the bent portion 41. If it does in this way, the burden concerning the leaf | plate spring 40 at the time of rotation to the obstruction | occlusion direction of the inside handle 211 can be made small.
