Since the open lever 140 rotates clockwise, the first wire cable WC1 and the second wire cable WC2 are each pulled.

  When the first wire cable WC1 is pulled, the door closing latch unit CR is released. For example, even when the sliding door D is in the door closing state, the inside handle IH moves toward the vehicle rear side. This can be moved by opening the door.

  Further, when the second wire cable WC2 is pulled, the clutch mechanism of the closer device CL is disengaged. For example, even when the closer device CL is in operation, the inside handle IH is tilted to the rear side of the vehicle. Then, the transition operation from the half latch state to the full latch state can be interrupted.

  When the door operation lever 110 rotates clockwise in FIG. 19, the door opening operation detection unit 116 turns on the first door operation detection sensor S1, and therefore the detection result of the first door operation detection sensor S1. Based on this, it is possible to detect the tilting operation of the operation handle member 310 toward the vehicle rear side.

  Next, as shown in FIG. 17, when the operation handle member 310 of the inside handle IH is tilted toward the vehicle front side from the initial state (the closing operation of the inside handle IH), the operation output unit 311 becomes the output unit engagement hole. Abutting on the rear abutting surface 117b of 117, the door operation lever 110 is rotated counterclockwise in FIG. When the door operation lever 110 rotates counterclockwise as shown in FIG. 20, the second door operation detection sensor S <b> 2 is turned on by the door closing operation detection unit 118. When the second door operation detection sensor S2 is turned on, as described above, the release actuator RA is driven by this ON operation as a trigger, and the open handle lever 170 is rotated counterclockwise in FIG. 5 via the fifth wire cable WC5. Rocks. Then, the rotation of the open handle lever 170 is transmitted to the lower open lever 160 via the first lever engaging portion 172, and is also transmitted to the open sub lever 150 via the second lever engaging portion 173, as shown in FIG. As shown in FIG. 1, each of them rotates clockwise.

  When the lower open lever 160 rotates clockwise, the third wire cable WC3 is pulled, and the door opening latch unit OR is released. As a result, for example, even when the slide door D is in the open state, the inside handle IH can be operated to close the door.

  When the open sub lever 150 rotates clockwise, the rotation is transmitted to the open lever 140 through the lock pin engaging portion 153 and the lock pin 201, and the first wire cable WC1 is rotated by rotating the open lever 140 clockwise. And the second wire cable WC2 is pulled. When the first wire cable WC1 is pulled, the door closing latch unit CR is released. For example, even when the sliding door D is in the door closing state, the inside handle IH moves toward the vehicle rear side. This can be moved by opening the door. When the second wire cable WC2 is pulled, the clutch mechanism of the closer device CL is disengaged. For example, even when the closer device CL is operating, if the inside handle IH is tilted to the rear side of the vehicle, Thus, the transition operation from the half latch state to the full latch state can be interrupted.

  Moreover, when the door operation lever 110 rotates counterclockwise as shown in FIG. 20, this rotation is transmitted to the lower open lever 160 via the first connecting link L1, and the lower open lever 160 rotates clockwise.

  When the lower open lever 160 rotates clockwise, the third wire cable WC3 is pulled, and the door opening latch unit OR is released. As a result, for example, even when the slide door D is in the open state, if the inside handle IH is tilted to the front side of the vehicle, it can be moved to close the door.

  When the door operation lever 110 rotates counterclockwise, the door closing operation detection unit 118 turns on the second door operation detection sensor S2. Therefore, based on the detection result of the second door operation detection sensor S2. It is possible to detect a tilting operation of the operation handle member 310 toward the vehicle front side.

  Next, when the outside handle OH is operated from the initial state, the open handle lever 170 rotates clockwise via the fourth wire cable WC4 as shown in FIG. The rotation of the open handle lever 170 is transmitted to the lower open lever 160 via the first lever engaging portion 172, and is also transmitted to the open sub lever 150 via the second lever engaging portion 173. Will rotate.

  When the lower open lever 160 rotates clockwise, the third wire cable WC3 is pulled, and the door opening latch unit OR is released. As a result, for example, even when the slide door D is in an open state, the outside handle OH can be operated to close the door.

  On the other hand, when the open sub lever 150 rotates clockwise, it is transmitted to the open lever 140 through the lock pin engaging portion 153 and the lock pin 201, and the first wire cable WC1 and the open lever 140 rotate clockwise. The second wire cables WC2 are each pulled. As a result, even when the slide door D is in the closed state, for example, the door can be opened by operating the outside handle OH, and the closer device CL is operating, for example. Even in the state, if the outside handle OH is operated, the transition operation from the half latch state to the full latch state can be interrupted.

  In the above-described operation, one end portion of the first connection link L1 appropriately moves in the first slide groove hole 114a of the door operation lever 110. Therefore, the door operation lever 110 may be moved depending on the clockwise rotation of the lower open lever 160. It will not work. Similarly, since one end portion of the second connection link L2 appropriately moves in the second slide groove hole 123a of the link lever 120, the link lever 120 does not operate due to the clockwise rotation of the open sub lever 150.

  When the open handle lever 170 rotates clockwise, the third door operation detection unit 175 turns on the third door operation detection sensor S3. Therefore, based on the detection result of the third door operation detection sensor S3. Thus, the operation of the outside handle OH can be detected.

  When the control unit 100 is switched from the initial state to the locked state, the lock pin 201 occupies outside the rotational movement range of the lock pin engaging portion 153 in the lock pin slide groove 141a of the open lever 140 as shown in FIG. It will be. Therefore, when the inside handle IH is tilted toward the rear side of the vehicle from this locked state, as shown in FIG. 23, the clockwise rotation of the door operation lever 110 is performed via the link lever 120 and the second connecting link L2. Although the rotation is transmitted to the open sub lever 150, the rotation of the open sub lever 150 is not transmitted to the open lever 140. Further, even when the first door operation detection sensor S1 is turned on by the rotation of the door operation lever 110 and the open handle lever 170 is rotated by using the ON state as a trigger, the open sub lever 150 accompanying the rotation of the open handle lever 170 is used. Is not transmitted to the open lever 140. As a result, the door closing latch unit CR is not released. For example, when the slide door D is in the door closing state, it cannot be moved to open the door. However, even in the locked state, the opening operation detection unit 116 turns on the first door operation detection sensor S1 by the rotation of the door operation lever 110. Therefore, based on the detection result of the first door operation detection sensor S1. Thus, it is possible to detect the tilting operation of the inside handle IH toward the vehicle rear side.

  Further, when the outside handle OH is operated from the locked state shown in FIG. 22, the rotation of the open sub lever 150 accompanying the rotation of the open handle lever 170 is transmitted to the open lever 140 as shown in FIG. There is nothing. As a result, the door closing latch unit CR is not released. For example, when the slide door D is in the door closing state, it cannot be moved to open the door. However, even in the locked state, the rotation of the open handle lever 170 is transmitted to the lower open lever 160 via the first lever engaging portion 172, and the third wire cable WC3 is pulled. When D is in the open state, it can be moved to close the door by operating the outside handle OH. Even in the locked state, the third door operation detection unit 175 turns on the third door operation detection sensor S3 due to the rotation of the open handle lever 170. Therefore, the detection result of the third door operation detection sensor S3 Based on this, it is possible to detect the operation of the outside handle OH.

  On the other hand, when the child lock lever 130 is switched to the locked position from the above-described initial state, the engagement pin 134 of the link slide portion 122 of the link lever 120 is connected to the link engagement portion 112 of the door operation lever 110 as shown in FIG. It will be occupied outside the rotational movement range. Therefore, even if the inside handle IH is tilted toward the vehicle rear side from this state, as shown in FIG. 26, the rotation of the door operation lever 110 is not transmitted to the link lever 120, that is, the link engagement. Since the portion 112 does not contact the engaging pin 134, the link lever 120 does not rotate, and the closing latch unit CR is not released. However, even in this state, if the control unit 100 is in the unlocked state, the lower open lever 160 and the open sub lever 150 are rotated clockwise by the operation of the outside handle OH. It can be opened and closed. Further, since the opening operation detection unit 116 turns on the first door operation detection sensor S1 by the rotation of the door operation lever 110, the inside handle IH is controlled based on the detection result of the first door operation detection sensor S1. It is possible to detect a tilting operation toward the rear side of the vehicle.

  As described above, according to the door opening and closing device, the operation output unit 311 formed on the inside handle IH is directly brought into contact with the door operation lever 110 to transmit power between them. The work of linking the inside handle IH and the door operation lever 110 is not necessary, and the assembling work can be easily performed. Moreover, since the door opening latch unit OR and the door closing latch unit CR are selectively released by the single door operation lever 110, it is possible to facilitate the assembly work due to the reduction in the number of handling parts. It becomes.
