When the open cable 92W is pulled toward the remote control device 91, the open lever 60 is rotated and the pressing piece 61 pushes down the pole drive lever 33, thereby moving to the release position of the pole 30 as described above. The rotation restriction of the latch 20 by the pole 30 is released.

  The positioning lever 63 is provided so as to overlap the open lever 60, and an interlocking contact piece 63 </ b> T standing from the side edge of the positioning lever 63 faces the one side edge of the open lever 60 from the side. When the open cable 92W is pulled toward the remote control device 91 and the open lever 60 is rotated, the interlocking contact piece 63T is pushed by the open lever 60 and the positioning lever 63 is also rotated and separated from the contact roller 57. Thus, as described above, the transmission of power from the active lever 50 to the seesaw-type rotating plate 55 is interrupted, and the latch drive lever 25 cannot be pushed up by the push-up wall 56 of the seesaw-type rotating plate 55. In the present embodiment, the position where the positioning lever 63 contacts the contact roller 57 corresponds to the “power transmission position” according to the “positioning movable member” according to the present invention, and the positioning lever 63 contacts the contact roller. The position separated from 57 corresponds to the “power cutoff position” according to the “positioning movable member”.

  Above the open lever 60, a release input panel 70, a slide rotation board 75 (corresponding to "slide rotation part" according to the present invention) and a release lever 65 (corresponding to "release rotation part" according to the present invention). Is supported so as to be pivotable about a common pivot shaft 65J to constitute the "first cancel mechanism" according to the present invention. As shown in FIG. 15A, the release input board 70 has a first rotating piece 70A extending downward from the rotating shaft 65J and a second rotating piece 70B extending in the lateral direction. . A slot 70R is formed in the second rotating piece 70B along an axis perpendicular to the rotating shaft 65J. Further, a stopper contact portion 70C facing upward is formed at the tip of the second rotating piece 70B. As shown in FIG. 7, the stopper contact portion 70 </ b> C contacts the stopper 81 </ b> S provided on the mechanism plate 81, and the release input board 70 is positioned at one end of the rotatable range.

  The lower end portion of the first rotating piece 70A is bent and raised toward the mechanism plate 81, and the bent and raised portion is projected to the opposite side of the latch and pole mechanism 20K and bent into a U shape as shown in FIG. Thus, a curved contact portion 70T is formed. Then, when the active lever 50 is rotated clockwise by the latch drive motor 41M, the pressing portion 50T provided in the active lever 50 contacts the curved contact portion 70T, and the release input board 70 is shown in FIG. It rotates counterclockwise.

  The slide rotation board 75 is disposed between the release input board 70 and the mechanism plate 81 as shown in FIG. The slide rotation board 75 extends in the longitudinal direction of the second rotation piece 70B of the release input board 70, and the width on the distal end side is tapered, while the proximal end side is widened toward the end. As shown in FIG. 15B, a long hole 77 extending in the longitudinal direction is formed in the slide rotation board 75, and a pair of parallel holes is formed on both sides of the long hole 77. Slits 78, 78 are formed. Further, a pair of protrusions 76A and 76A are formed on both inner side surfaces of the long hole 77 at a position near the base end of the long hole 77 (a position near the right end in FIG. 15B). Then, due to the engagement between the rotation shaft 65J penetrating the base end portion of the long hole 77 and the protrusions 76A and 76A, the slide rotation plate 75 moves in a direction orthogonal to the axial direction of the rotation shaft 65J. It is regulated. Further, when an external force is applied in the longitudinal direction of the slide rotation board 75, the doubly supported beam portions 76 between the long holes 77 and the respective slits 78 are deflected so that the protrusions 76A and 76A get over the rotation shaft 65J, and the slide rotation The moving board 75 can be slid. Here, the position of the slide rotation board 75 when the rotation shaft 65J is arranged at the base end portion (the right end portion in FIG. 15B) of the long hole 77 is the “slide rotation component according to the present invention. The position of the slide rotation board 75 when the rotation shaft 65J is disposed at the distal end portion of the elongated hole 77 (the left end portion in FIG. 15B) corresponds to the “power transmission position”. This corresponds to the “power cutoff position” related to the “sliding rotation part”.

  A cancel operation protrusion 75B (corresponding to a “cancel operation unit” according to the present invention) for sliding the slide rotation board 75 between the power transmission position and the power cutoff position is provided on the slide rotation board 75. It is provided at the base end. As shown in FIG. 14, the base end portion of the slide rotation board 75 is exposed to the side from the outer edge portion of the mechanism plate 81, and the cancel operation projection 75B projects from the exposed portion. In addition, a connecting swiveling protrusion 75A protrudes from the distal end portion of the release input board 70 on the side away from the mechanism plate 81. The connecting swiveling protrusion 75A is formed in a rectangular column shape having substantially the same width as the long hole 70R of the release input panel 70, and is received in a crank groove 65R of the release lever 65 described below through the long hole 70R. Has been.

  As shown in FIG. 15C, the release lever 65 extends obliquely downward from the rotation shaft 65J, and one end of a release cable 91W is connected to the lower end of the release lever 65 as shown in FIG. The other end of the release cable 91W is connected to the remote control device 91, and an intermediate portion of the release cable 91W is covered with a cladding tube 91H. Further, the release lever 65 is urged clockwise by the spring 82 in FIG. Further, the release lever 65 has a fan-shaped portion extending from the base end portion near the rotation shaft 65J to the intermediate portion, and a crank groove 65R is formed there. As shown in FIG. 15C, the crank groove 65R includes an arc-shaped outer arc groove 65R1 centering on the rotation shaft 65J, and an inner arc groove 65R2 having a smaller radius of curvature than the outer arc groove 65R1 (according to the present invention). (Corresponding to the “projection receiving part”), and the whole is substantially crank-shaped. As shown in FIGS. 7 to 11, when the slide turntable 75 is disposed at the power transmission position, the connecting turning projection 75A is received in the outer arc groove 65R1, and the slide turntable 75 is moved to the power cutoff position. When connected to the inner circular groove 65R2, the connecting turning protrusion 75A is received in the inner circular groove 65R2.

  Here, when the release input board 70 is rotated by receiving power from the active lever 50 in a state where the connecting turning protrusion 75A is received in the outer circular groove 65R1, the slide turning board 75 is rotated integrally therewith. Then, as shown in the change from FIG. 9 to FIG. 10, the connecting turning protrusion 75A moves the outer arc groove 65R1 from one end to the other end, and contacts the protrusion abutting section 65S1 at the end of the outer arc groove 65R1. Touch. When the release input board 70 and the slide rotation board 75 are further rotated, as shown in the change in FIGS. 10 to 11, the connection turning protrusion 75A pushes the protrusion contact part 65S1, so that the release lever 65 is moved. The open cable 92W can be pulled from the remote control device 91 to the closer device 10B side by rotating by receiving power from the slide rotating plate 75.

  Further, as shown in FIG. 11, when the connected turning protrusion 75A comes into contact with the protrusion contact part 65S1, the slide turn board 75 is moved to the power cut-off position, and the connected turning protrusion 75A is moved to the inner side. It can move to the arc groove 65R2. Then, the transmission of power from the connecting turning protrusion 75A to the release lever 65 is cut off, and the connecting turning protrusion 75A can turn relatively freely in the inner arc groove 65R2, and the slide turning plate 75 releases the release lever. Transmission of power and reaction force to 65 is cut off.

  Although not shown, the fully open door lock device 10C has a latch and pawl mechanism that operates in the same manner as the closed door lock device 10A. Similarly to the closed door lock device 10A, the pole of the fully open door lock device 10C is provided with a pole drive lever, and the pole drive lever and the remote control device 91 are connected by an open cable 94W (see FIG. 2). .

  As conceptually shown in FIG. 16, the remote control device 91 includes a remote control turning lever 98 to which the open cables 92W, 93W, 94W are connected at one end. The remote control pivot lever 98 is biased and positioned at the origin position (position shown in FIG. 16) by the first origin holding spring 98S and the stopper 98T. Further, the release cable 91W is connected to the opposite end of the remote control turning lever 98 with respect to the connecting portion with the open cables 92W, 93W, 94W across the turning center. Accordingly, when the latch drive motor 41M is driven and the release cable 91W is pulled toward the closer device 10B, the remote control rotation lever 98 is rotated in a direction away from the origin position (counterclockwise direction in FIG. 16), and the open cable 92W, 93W, and 94W are pulled to the remote control device 91 side. As a result, all the poles 30 of the closing door lock device 10A, the closer device 10B, and the fully open door lock device 10C are moved to the release position, and the rotation restriction of all the latches 20 is released at once.

  The remote control device 91 includes a handle 95 that is separately provided on the inner surface and the outer surface of the slide door 90. The handles 95 are urged and held at the origin position by the second origin holding spring 97S and the stopper 97T. When the handle 95 is moved away from the origin position against the second origin holding spring 97S, the handle interlocking component 97 connected to the handle 95 passes through the predetermined single movable range L1 from the origin position, It contacts the remote control turning lever 98. Then, when the handle 95 is moved further away from the origin position in this state, the handle interlocking component 97 pushes and rotates the remote control turning lever 98. Further, the remote control device 91 is provided with a handle operation detection sensor 96 for detecting that the handle interlocking component 97 has entered the single movable range L1 from the origin position side. Further, the detection signal of the steering operation detection sensor 96 is taken into an ECU (not shown) provided in the vehicle main body 99 together with the detection signal of the latch position detection sensor 83. Then, the ECU drives the latch drive motor 41M based on these detection signals as described in detail below.

  This completes the description of the configuration of the present embodiment. Next, the function and effect of the present embodiment having the above configuration will be described. When the sliding door 90 is tightened, the latches 20 of the closing door lock device 10A and the closer device 10B are engaged with the corresponding strikers 40 and rotated. At this time, when the sliding door 90 is closed with a relatively strong force and the sliding door 90 is fully closed, the latches 20 of the closing door locking device 10A and the closing device 10B reach the full latching position as shown in FIGS. The pawls 30 (specifically, the latch pivot restricting pieces 31 of the pawls 30) are engaged with the latches 20, and the pivots of the latches 20 in the unlocking direction are restricted (prohibited). As a result, the slide door 90 is held in the fully closed state.

  In addition, when the sliding door 90 is closed with a relatively weak force and is in a half-door state, the latches 20 of the closing door lock device 10A and the closer device 10B rotate to the half latch position as shown in FIGS. Thus, the pawls 30 engage with the latches 20, and the rotation of the latches 20 in the unlocking direction is restricted (prohibited) and held in a half-door state. Then, the latch position detection sensor 83 of the closer device 10B detects that the latch 20 is located at the half latch position, and the detection result is taken into the ECU. Then, the ECU rotates the motor output shaft of the latch drive motor 41M provided in the closer device 10B to one side, and rotationally drives the active lever 50 in the counterclockwise direction in FIG. At this time, the positioning lever 63 comes into contact with the contact roller 57 to position one end portion of the seesaw-type rotating plate 55, and the active lever 50 lifts the rotating shaft 55J of the seesaw-type rotating plate 55 to activate it. Power is transmitted from the lever 50 to the seesaw-type rotating plate 55, and the other end of the seesaw-type rotating plate 55 (specifically, the tip of the push-up wall 56 provided on the seesaw-type rotating plate 55) is latched. The latch drive lever 25 is pushed up. Thereby, the latch 20 moves from the half latch position shown in FIG. 8 to the full latch position shown in FIG. 9, and the slide door 90 is held from the half door state to the fully closed state.

  Here, when the handle 95 is operated during the transition from the half-door state to the fully-closed state, the open cable 92W is pulled toward the remote control device 91, and the positioning lever 63 is moved from the contact roller 57 of the seesaw-type rotating board 55. Separate. As a result, the transmission of power from the active lever 50 to the seesaw-type rotating board 55 is urgently interrupted, and the transition from the half door state to the fully closed state can be cancelled. Then, the open lever 60 also rotates in conjunction with the operation of the handle 95, and the pressing piece 61 of the open lever 60 pushes down the pole drive lever 33 of the pole 30, so that the pole 30 of the closer device 10B is temporarily engaged with the latch 20. Even if they are aligned, they can move to the release position. Further, since the other open cable 93W is also pulled toward the remote control device 91 by the operation of the handle 95, the pole 30 in the closing door lock device 10A also moves to the release position. Thereby, the slide door 90 can be opened.

  When the sliding door 90 is fully closed, the soundproof member is crushed between the sliding door 90 and the door frame 99W, and the reaction force causes the poles 30 and the latches of the closing door lock device 10A and the closer device 10B. 20 is in frictional engagement. On the other hand, in order to open the sliding door 90, it is necessary to move both the poles 30 of the closing door lock device 10A and the closer device 10B to the release position against the frictional resistance between the poles 30 and the latch 20, and only manual operation is required. A large force is required to move both poles 30 to the release position. However, in this embodiment, when the handle 95 is operated, the handle operation detection sensor 96 detects that the handle 95 has been operated before the frictional resistance between the pole 30 and the latch 20 is applied to the handle 95, and receives this. The ECU rotates the motor output shaft of the latch drive motor 41M to the other side.

  Then, the active lever 50 is rotationally driven in the clockwise direction in FIG. 10, and the release input board 70 and the slide rotation board 75 are rotated in the counterclockwise direction in FIG. Then, the connecting turning protrusion 75A of the slide turn board 75 contacts the protrusion contact portion 65S1 on one end side of the outer arc groove 65R1 of the release lever 65, and as shown in the change of FIGS. 10 to 11, the release lever 65 rotates together with the release input board 70 and the slide rotation board 75, and pulls the open cable 92W toward the closer device 10B. As a result, the remote control turning lever 98 of the remote control device 91 is turned, the open cables 92W and 93W are pulled toward the remote control device 91, and both the closed door lock device 10A and the closer device 10B are driven by the power of the latch drive motor 41M. The pole 30 can be moved to the release position, and the slide door 90 can be easily opened.

  Further, when the slide door 90 is fully opened, the latch 20 and the striker 40 (not shown) of the fully open door lock device 10 </ b> C are engaged with each other, and the pawl 30 is frictionally engaged with the latch 20. Also in this case, by operating the handle 95, the open cable 94W is pulled toward the remote control device 91, and the pole 30 of the fully open door lock device 10C can be moved to the release position by the power of the latch drive motor 41M. Thereby, the slide door 90 can be easily closed.

  Here, as shown in FIG. 11, when the release input panel 70 and the slide rotation panel 75 are abnormally stopped together with the latch drive motor 41M in a state where the open cable 92W is pulled from the remote control device 91 to the closer device 10B side. The ECU detects this abnormal stop from the energized state of the latch drive motor 41M and the like, for example, turns on a warning light (not shown) corresponding to the “abnormality notification means” according to the present invention. In this case, the driver only has to move the slide turnboard 75 to the power cutoff position. Then, the contact between the connecting turning protrusion 75A and the protrusion contact portion 65S1 is released, and the connecting turning protrusion 75A is received in the inner circular groove 65R2. Note that the warning lamp is turned off by detecting that the slide rotating board 75 has been operated to an appropriate position. Then, transmission of power from the connecting turning protrusion 75A to the release lever 65 is interrupted, and the release lever 65 is pulled by the spring 82 so that the connecting turning protrusion 75A turns relatively in the inner arc groove 65R2. Is returned to the original position. As a result, the remote control pivot lever 98 also returns to the home position, and even if the latch drive motor 41M stops abnormally, the pole 30 of the closed door lock device 10A, the closer device 10B, and the fully open door lock device 10C is moved from the release position to the latch 20. The position can be returned to the engaged position, and the slide door 90 can be held in the closed state.

  As described above, according to the vehicle door lock system 10 of the present embodiment, the power source for turning the latch drive motor 41M from the half-door state to the fully-closed state and the power for assisting the steering operation when the slide door 90 is opened. It can be used both as a source and manufacturing cost and weight can be reduced. Further, when the latch drive motor 41M becomes inoperable with the pole 30 held at the release position, an abnormality is notified by a warning lamp, so that a quick response is possible. The abnormality notification means may be a warning sound or an alarm other than the warning light.

  Further, as shown in FIG. 11, when the connected turning protrusion 75A comes into contact with the protrusion contact part 65S1, the slide turn board 75 is moved to the power cut-off position, and the connected turning protrusion 75A is moved to the inner side. It can move to the arc groove 65R2. Then, the transmission of power from the connecting turning protrusion 75A to the release lever 65 is cut off, and the connecting turning protrusion 75A can turn relatively freely in the inner arc groove 65R2, and the slide turning plate 75 releases the release lever. Transmission of power and reaction force to 65 is cut off.

  Although not shown, the fully open door lock device 10C has a latch and pawl mechanism that operates in the same manner as the closed door lock device 10A. Similarly to the closed door lock device 10A, the pole of the fully open door lock device 10C is provided with a pole drive lever, and the pole drive lever and the remote control device 91 are connected by an open cable 94W (see FIG. 2). .

  As conceptually shown in FIG. 16, the remote control device 91 includes a remote control turning lever 98 to which the open cables 92W, 93W, 94W are connected at one end. The remote control pivot lever 98 is biased and positioned at the origin position (position shown in FIG. 16) by the first origin holding spring 98S and the stopper 98T. Further, the release cable 91W is connected to the opposite end of the remote control turning lever 98 with respect to the connecting portion with the open cables 92W, 93W, 94W across the turning center. Accordingly, when the latch drive motor 41M is driven and the release cable 91W is pulled toward the closer device 10B, the remote control rotation lever 98 is rotated in a direction away from the origin position (counterclockwise direction in FIG. 16), and the open cable 92W, 93W, and 94W are pulled to the remote control device 91 side. As a result, all the poles 30 of the closing door lock device 10A, the closer device 10B, and the fully open door lock device 10C are moved to the release position, and the rotation restriction of all the latches 20 is released at once.

The remote control device 91 is provided with handles 95 that are positioned separately on the inside and outside of the slide door 90. The handles 95 are urged and held at the origin position by the second origin holding spring 97S and the stopper 97T. When the handle 95 is moved away from the origin position against the second origin holding spring 97S, the handle interlocking component 97 connected to the handle 95 passes through the predetermined single movable range L1 from the origin position, It contacts the remote control turning lever 98. Then, when the handle 95 is moved further away from the origin position in this state, the handle interlocking component 97 pushes and rotates the remote control turning lever 98. Further, the remote control device 91 is provided with a handle operation detection sensor 96 for detecting that the handle interlocking component 97 has entered the single movable range L1 from the origin position side. Further, the detection signal of the steering operation detection sensor 96 is taken into an ECU (not shown) provided in the vehicle main body 99 together with the detection signal of the latch position detection sensor 83. Then, the ECU drives the latch drive motor 41M based on these detection signals as described in detail below.

This completes the description of the configuration of the present embodiment. Next, the function and effect of the present embodiment having the above configuration will be described. When the sliding door 90 is tightened, the latches 20 of the closing door lock device 10A and the closer device 10B are engaged with the corresponding strikers 40 and rotated. At this time, when the sliding door 90 is closed with a relatively strong force and the sliding door 90 is fully closed, the latches 20 of the closing door locking device 10A and the closing device 10B reach the full latching position as shown in FIGS. The pawls 30 (specifically, the latch pivot restricting pieces 31 of the pawls 30) are engaged with the latches 20, and the pivots of the latches 20 in the latch release direction are restricted (prohibited). As a result, the slide door 90 is held in the fully closed state.

In addition, when the sliding door 90 is closed with a relatively weak force and is in a half-door state, the latches 20 of the closing door lock device 10A and the closer device 10B rotate to the half latch position as shown in FIGS. Thus, the pawls 30 engage with the latches 20, and the rotation of the latches 20 in the latch release direction is restricted (prohibited) and held in a half-door state. Then, the latch position detection sensor 83 of the closer device 10B detects that the latch 20 is located at the half latch position, and the detection result is taken into the ECU. Then, the ECU rotates the motor output shaft of the latch drive motor 41M provided in the closer device 10B to one side, and rotationally drives the active lever 50 in the counterclockwise direction in FIG. At this time, the positioning lever 63 comes into contact with the contact roller 57 to position one end portion of the seesaw-type rotating plate 55, and the active lever 50 lifts the rotating shaft 55J of the seesaw-type rotating plate 55 to activate it. Power is transmitted from the lever 50 to the seesaw-type rotating plate 55, and the other end of the seesaw-type rotating plate 55 (specifically, the tip of the push-up wall 56 provided on the seesaw-type rotating plate 55) is latched. The latch drive lever 25 is pushed up. Thereby, the latch 20 moves from the half latch position shown in FIG. 8 to the full latch position shown in FIG. 9, and the slide door 90 is held from the half door state to the fully closed state.

  Here, when the handle 95 is operated during the transition from the half-door state to the fully-closed state, the open cable 92W is pulled toward the remote control device 91, and the positioning lever 63 is moved from the contact roller 57 of the seesaw-type rotating board 55. Separate. As a result, the transmission of power from the active lever 50 to the seesaw-type rotating board 55 is urgently interrupted, and the transition from the half door state to the fully closed state can be cancelled. Then, the open lever 60 also rotates in conjunction with the operation of the handle 95, and the pressing piece 61 of the open lever 60 pushes down the pole drive lever 33 of the pole 30, so that the pole 30 of the closer device 10B is temporarily engaged with the latch 20. Even if they are aligned, they can move to the release position. Further, since the other open cable 93W is also pulled toward the remote control device 91 by the operation of the handle 95, the pole 30 in the closing door lock device 10A also moves to the release position. Thereby, the slide door 90 can be opened.

  When the sliding door 90 is fully closed, the soundproof member is crushed between the sliding door 90 and the door frame 99W, and the reaction force causes the poles 30 and the latches of the closing door lock device 10A and the closer device 10B. 20 is in frictional engagement. On the other hand, in order to open the sliding door 90, it is necessary to move both the poles 30 of the closing door lock device 10A and the closer device 10B to the release position against the frictional resistance between the poles 30 and the latch 20, and only manual operation is required. A large force is required to move both poles 30 to the release position. However, in this embodiment, when the handle 95 is operated, the handle operation detection sensor 96 detects that the handle 95 has been operated before the frictional resistance between the pole 30 and the latch 20 is applied to the handle 95, and receives this. The ECU rotates the motor output shaft of the latch drive motor 41M to the other side.

Then, the active lever 50 is rotationally driven in the clockwise direction in FIG. 10, and the release input board 70 and the slide rotation board 75 are rotated in the counterclockwise direction in FIG. Then, the connecting turning protrusion 75A of the slide turn board 75 contacts the protrusion contact portion 65S1 on one end side of the outer arc groove 65R1 of the release lever 65, and as shown in the change of FIGS. 10 to 11, the release lever 65 rotates together with the release input board 70 and the slide rotation board 75 to pull the release cable 91W toward the closer device 10B. As a result, the remote control turning lever 98 of the remote control device 91 is turned, the open cables 92W and 93W are pulled toward the remote control device 91, and both the closed door lock device 10A and the closer device 10B are driven by the power of the latch drive motor 41M. The pole 30 can be moved to the release position, and the slide door 90 can be easily opened.

  Further, when the slide door 90 is fully opened, the latch 20 and the striker 40 (not shown) of the fully open door lock device 10 </ b> C are engaged with each other, and the pawl 30 is frictionally engaged with the latch 20. Also in this case, by operating the handle 95, the open cable 94W is pulled toward the remote control device 91, and the pole 30 of the fully open door lock device 10C can be moved to the release position by the power of the latch drive motor 41M. Thereby, the slide door 90 can be easily closed.

Here, as shown in FIG. 11, when the release cable 91W is pulled from the remote control device 91 to the closer device 10B side, the release input panel 70 and the slide rotation board 75 together with the latch drive motor 41M abnormally stop. The ECU detects this abnormal stop from the energized state of the latch drive motor 41M, for example, and turns on a warning light on the driver's seat (not shown). In this case, the driver only has to move the slide turnboard 75 to the power cutoff position. Then, the contact between the connecting turning protrusion 75A and the protrusion contact portion 65S1 is released, and the connecting turning protrusion 75A is received in the inner circular groove 65R2. Note that the warning lamp is turned off by detecting that the slide rotating board 75 has been operated to an appropriate position. Then, transmission of power from the connecting turning protrusion 75A to the release lever 65 is interrupted, and the release lever 65 is pulled by the spring 82 so that the connecting turning protrusion 75A turns relatively in the inner arc groove 65R2. Is returned to the original position. As a result, the remote control pivot lever 98 also returns to the home position, and even if the latch drive motor 41M stops abnormally, the pole 30 of the closed door lock device 10A, the closer device 10B, and the fully open door lock device 10C is moved from the release position to the latch 20. The position can be returned to the engaged position, and the slide door 90 can be held in the closed state.

  As described above, according to the vehicle door lock system 10 of the present embodiment, the power source for turning the latch drive motor 41M from the half-door state to the fully-closed state and the power for assisting the steering operation when the slide door 90 is opened. It can be used both as a source and manufacturing cost and weight can be reduced. Further, when the latch drive motor 41M becomes inoperable with the pole 30 held at the release position, an abnormality is notified by a warning lamp, so that a quick response is possible. The abnormality notification means may be a warning sound or an alarm other than the warning light.
