  The lock lever 640 has a button connecting portion 641. The button connecting portion 641 is a tip portion of a lock lever 640 that extends radially outward from the rotation shaft portion 635 of the connect lever 630. A lock button link means 642 such as a link or a wire linked to the inside lock button 6 provided on the indoor side of the door D is connected to the button link portion 641. That is, when the inside lock button 6 is locked, the driving force is transmitted to the lock lever 640 via the lock button link means 642, and the lock lever 640 rotates counterclockwise in FIG. The rotation shaft portion 635 is rotated counterclockwise. On the other hand, when the inside lock button 6 is unlocked, the driving force is transmitted to the lock lever 640 via the lock button link means 642, and the lock lever 640 rotates clockwise in FIG. The moving shaft portion 635 is rotated clockwise. As described above, the driving force from the outside of the housing 10 that has operated the inside lock button 6 is transmitted to the lock lever 640 via the lock button linking means 642 and is input to the rotation shaft portion 635 as an input portion. The rotating shaft portion 635 to which the driving force from the outside of the housing 10 is input switches the lock mechanism 600 between the unlocked state and the locked state.

The state maintaining projection 653 extends substantially horizontally along the interior / exterior direction of the vehicle body on the surface facing the main case 2. Then, the spring 657 attached to the main case 2 holds the state maintaining protrusion 653 so that the unlocked state (FIG. 9-1) or the locked state (FIG. 9-2) is maintained.

  The driven gear portion 654 of the sector gear 650 is formed in a fan shape with the gear shaft 651 as the center, as shown in FIG. The driven gear portion 654 has a pair of outer teeth 654a and 654b, a first passive tooth 654c, and a second passive tooth 654d on the outer peripheral surface thereof. The pair of outer teeth 654a and 654b, the first passive teeth 654c, and the second passive teeth 654d are provided at three stages having different heights along the extending direction of the gear shaft 651. The pair of outer teeth 654a and 654b are provided on both sides of the driven gear portion 654, and are disposed at positions closest to the indoor side. The first passive tooth 654c is provided at a position close to the one outer tooth 654a between the pair of outer teeth 654a and 654b, and is disposed at an intermediate position along the extending direction of the gear shaft 651. It is. The second passive tooth 654d is provided at a position between the other outer tooth 654b and the first passive tooth 654c, and is disposed at a position that is the most outdoor side.

  The panic lever contact portion 655 of the sector gear 650 is formed so as to protrude from the vehicle rear side edge portion of the sector gear 650 to the indoor side.

  As shown in FIG. 9, the panic lever 660 connects the sector gear 650 and the link lever 40. The panic lever 660 is rotatably attached to the gear shaft 651. The panic lever 660 is formed so as to extend radially outward from the gear shaft 651 and is provided with a connecting convex portion 661 and a sector gear abutting portion 662.

  The connecting convex portion 661 of the panic lever 660 is a cylindrical portion that protrudes substantially horizontally from the surface located on the indoor side at the tip of the panic lever 660 along the interior / exterior direction of the vehicle body. The connecting projection 661 is mounted in the connecting groove 40e of the link lever 40 described above.

  The sector gear contact portion 662 of the panic lever 660 is a step portion formed on the vehicle rear side in the middle portion of the panic lever 660. The sector gear abutting portion 662 abuts on the panic lever abutting portion 655 of the sector gear 650 and can be interlocked.

  Note that a panic spring 663 is interposed between the sector gear 650 and the panic lever 660, and the sector gear contact portion 662 of the panic lever 660 is biased so as to contact the panic lever contact portion 655 of the sector gear 650. It is.

  As shown in FIG. 10, the worm wheel 670 is rotatably disposed above the sector gear 650 via a worm shaft 671 extending substantially horizontally along the indoor / outdoor direction of the vehicle body. An intermittent gear 672 is fixed to the worm wheel 670 on the same axis.

  The intermittent gear 672 of the worm wheel 670 has a basic tooth 672a, a pair of first drive teeth 672b, and a pair of second drive teeth 672c. The intermittent gear 672 constitutes a one-way power transmission means between the pair of outer teeth 654a, 654b, the first passive teeth 654c, and the second passive teeth 654d provided in the driven gear portion 654 of the sector gear 650. That is, the basic teeth 672a, the pair of first drive teeth 672b, and the pair of second drive teeth 672c of the intermittent gear 672 are a pair of outer teeth 654a, 654b, a first passive tooth 654c, and a second passive tooth of the driven gear portion 654. Similar to 654d, it is provided at three stages of different heights along the extending direction of the worm shaft 671. The basic teeth 672a mesh only with the outer teeth 654a and 654b, and the first drive teeth 672b Only the first passive tooth 654c is engaged, and the second driving tooth 672c is configured to engage only the second passive tooth 654d. Although not shown in the figure, between the worm wheel 670 and the main case 2, the basic teeth 672 a of the intermittent gear 672 of the worm wheel 670 are directed toward the axis of the gear shaft 651 (hereinafter simply neutral). A neutral return spring is provided to maintain the state.

  The sector gear 650 was rotated clockwise around the gear shaft 651 from the position shown in FIG. 10-1 (hereinafter simply referred to as the unlock position) to the position shown in FIG. 10-2 (hereinafter simply referred to as the lock position). In this case, since each tooth 654a, 654b, 654c, 654d of the driven gear portion 654 in the sector gear 650 does not mesh with any tooth 672a, 672b, 672c of the intermittent gear 672, the worm wheel 670 is not rotated.

  Similarly, when the sector gear 650 is rotated counterclockwise around the gear shaft 651 from the locked position shown in FIG. 10-2 to the unlocked position shown in FIG. 10-1, the worm wheel 670 is not rotated. Absent.

  As shown in FIG. 10, the worm wheel 670 meshes with a worm 674 fixed to the output shaft of the drive motor 673. The drive motor 673 is arranged at the uppermost position in the housing 10 as shown in FIG. For this reason, even if the grease applied to the mechanism arranged in the housing 10 is liquefied, it does not reach the position of the drive motor 673. That is, it is possible to prevent the grease from entering the drive motor 673.

  When the worm wheel 670 is rotated counterclockwise around the worm shaft 671 from the state shown in FIG. 10-1 by driving the drive motor 673, the first drive is performed after the basic teeth 672a mesh with the outer teeth 654a. The tooth 672b meshes with the first passive tooth 654c, and the second driving tooth 672b meshes with the second passive tooth 654d. As a result, as shown in FIG. 10B, the sector gear 650 rotates around the gear shaft 651 clockwise via the driven gear portion 654. Further, along with the clockwise rotation of the sector gear 650, the link lever 40 rotates counterclockwise around the open operation end 30b of the open lever 30 via the rotator 40aa and is displaced to the lock position. It will be.

  Note that after the link lever 40 is displaced from the unlock position shown in FIG. 10-1 to the lock position shown in FIG. 10-2 by the rotation of the worm wheel 670, the link lever 40 is no longer rotated by the intermittent gear 672. The worm wheel 670 returns to the neutral state without rotating the link lever 40 due to the elastic restoring force of the neutral return spring (not shown).

  Similarly, when the worm wheel 670 is rotated clockwise around the worm shaft 671 from the state shown in FIG. 10-2, the second drive teeth 672c are second after the basic teeth 672a mesh with the outer teeth 654b. The first drive tooth 672b meshes with the first passive tooth 654c. As a result, as shown in FIG. 10A, the sector gear 650 rotates around the gear shaft 651 counterclockwise via the driven gear portion 654. Further, as the sector gear 650 rotates counterclockwise, the link lever 40 rotates clockwise around the open operation end 30b of the open lever 30 via the rotator 40aa and is displaced to the unlock position. Will do.

  After the link lever 40 is displaced from the locked position shown in FIG. 10-2 to the unlocked position shown in FIG. 10-1 by the rotation of the worm wheel 670, the link lever 40 is no longer rotated by the intermittent gear 672. The worm wheel 670 returns to the neutral state without rotating the link lever 40 due to the elastic restoring force of the neutral return spring (not shown).

  In the lock mechanism 600 configured as described above, when in the unlocked state, the ratchet drive unit 40b of the link lever 40 is connected to the contact portion 25a of the ratchet lever 25 as shown in FIGS. 6-1 and 7-1. Located in the lower area.

  In this unlocked state, the outside handle 1 is operated to open the door, and the open lever 30 is rotated counterclockwise around the open lever shaft 31 in FIG. As a result, as shown in FIG. 6B, the ratchet driving portion 40b of the link lever 40 presses the contact portion 25a of the ratchet lever 25 to move upward as the open operation end portion 30b moves upward. . As a result, the contact engagement state between the hook portion 21b of the latch 21 and the engagement portion 22a of the ratchet 22 is released, and the door D can be opened with respect to the vehicle body.

  Further, in the unlocked state, the inside handle 5 is operated to open the door, and the inner handle lever 50 is rotated counterclockwise around the inner lever shaft 51 in FIG. As a result, as shown in FIG. 7-2, when the one motion link 56 moves upward, the contact portion 25a of the ratchet lever 25 is pressed and moved upward. As a result, the contact engagement state between the hook portion 21b of the latch 21 and the engagement portion 22a of the ratchet 22 is released, and the door D can be opened with respect to the vehicle body.

  Further, in the opened state of the door D, the door lock device cannot be locked by operating only the inside lock button 6. This is because when the door D is in the open state, that is, when the latch 21 and the ratchet 22 are not in the contact engagement state, as shown in FIGS. 4 and 6-1, the operating end 25b of the ratchet lever 25 and the link lever 40 are used. This is because the lock preventing portion 40d is adjacent and the operating end portion 25b of the ratchet lever 25 prevents the link lever 40 from swinging counterclockwise.

  However, when the door D is opened, the door lock device can be locked by operating the inside lock button 6 while the outside handle 1 or the inside handle 5 is opened. Even if the door D is in the open state, the link lever 40 is moved upward by the opening operation of the outside handle 1 or the inside handle 5 as shown in FIGS. The adjacent relationship between the operating end portion 25b of the lever 25 and the lock preventing portion 40d of the link lever 40 is eliminated, and the operating end portion 25b of the ratchet lever 25 does not prevent the link lever 40 from swinging counterclockwise. Because.

  If the inside lock button 6 is locked while the inside handle 5 is opened while the door D is open, the one-motion protrusion 634 presses the one-motion lever 53 as the connect lever 630 rotates. As a result, the one-motion lever 53 rotates around the one-motion lever connecting hole 50c against the urging force of the one-motion spring 54. Thereafter, when the opening operation of the inside handle 5 is interrupted, the one-motion lever 53 rotates around the one-motion lever connection hole 50c by the urging force of the one-motion spring 54 while the door lock device is kept locked. And return to the original position.

  On the other hand, when the inside lock button 6 in the unlocked state shown in FIG. 9-1 is locked in the closed state of the door D, the connect lever 630 is moved along with the rotation of the lock lever 640 as shown in FIG. It swings counterclockwise around the convex portion 201. As a result, the sector gear 650 connected to the connecting lever 630 via the connecting protrusion 636 and the connecting groove 656 is swung clockwise around the gear shaft 651. When the sector gear 650 swings clockwise, the panic lever contact portion 655 of the sector gear 650 presses the sector gear contact portion 662 of the panic lever 660, and the panic lever 660 rotates clockwise around the gear shaft 651. become. Further, with the rotation of the panic lever 660, the link lever 40 swings counterclockwise, and the lock mechanism 600 is locked.

  In this locked state, even if the outside handle 1 is operated to open the door and the open lever 30 is rotated clockwise in FIG. 1, the ratchet drive unit 40b of the link lever 40 as shown in FIG. And the contact portion 25a of the ratchet lever 25 are separated from each other, so that the ratchet drive portion 40b and the contact portion 25a do not contact each other, and the hook portion 21b of the latch 21 and the engagement portion 22a of the ratchet 22 The contact engagement state is not released. As a result, the door D is held in a closed state with respect to the vehicle body, and the vehicle can be locked.

  Note that the transition from the unlocked state shown in FIG. 9-1 to the locked state shown in FIG. 9-2 is not necessarily limited to the locking operation of the inside lock button 6, but by the drive motor 673 as shown in FIG. 10-2. The worm wheel 670 may be rotated counterclockwise around the worm shaft 671 and the sector gear 650 may be rotated clockwise around the gear shaft 651, or the key operation of the key cylinder KC as shown in FIG. Thus, the key sub lever 620 may be rotated counterclockwise around the convex portion 302.

  When the inside lock button 6 is unlocked from the locked state described above, the connect lever 630 swings clockwise as the lock lever 640 rotates, as shown in FIG. As a result, the sector gear 650 connected to the connecting lever 630 via the connecting projection 636 and the connecting groove 656 is swung counterclockwise around the gear shaft 651. When the sector gear 650 swings counterclockwise, the panic lever 660 biased by the panic spring 663 rotates counterclockwise around the gear shaft 651 in conjunction with the sector gear 650. Further, as the panic lever 660 rotates, the link lever 40 swings clockwise and the lock mechanism 600 is unlocked.

  In this unlocked state, when the inside handle 5 is operated to open the door, the locked state is switched to the unlocked state, the opening operation of the inside handle 5 is made effective, and the opening door operation of the inside handle 5 is transmitted to the ratchet 22. . Then, the door D can be opened.

  This will be described in more detail. When the inside handle 5 is operated to open the door in the locked state shown in FIG. 11A, the inner handle lever 50 swings around the inner lever shaft 51 counterclockwise as shown in FIG. 11B. When the inner handle lever 50 swings, the one motion lever 53 that rotates integrally with the inner handle lever 50 presses the one motion projection 634 of the connect lever 630 so that the connect lever 630 is moved around the convex portion 201. Rock clockwise. As the connect lever 630 swings, the sector gear 650 swings counterclockwise around the gear shaft 651, and the panic lever 660 biased by the panic spring 663 moves around the gear shaft 651 in conjunction with the sector gear 650. It will rotate counterclockwise. As the panic lever 660 rotates, the link lever 40 swings clockwise to switch the lock mechanism 600 to the unlocked state. At the same time, as the inner handle lever 50 swings counterclockwise, the one-motion link 56 presses the contact portion 25a of the ratchet lever 25, and the hook portion 21b of the latch 21 and the engagement portion 22a of the ratchet 22 contact each other. The engaged state can be released and an open door operation can be performed.

  The transition from the locked state shown in FIG. 9-2 to the unlocked state shown in FIG. 9-1 is not necessarily limited to the unlocking operation of the inside lock button 6 or the operation of the inside handle 5, but to FIG. As shown, the drive motor 673 may cause the worm wheel 670 to rotate clockwise about the worm shaft 671 and the sector gear 650 to rotate clockwise about the gear shaft 651, or as shown in FIG. The key sub lever 620 may be rotated around the convex portion 302 in the clockwise direction by the key operation of the key cylinder KC.

  In the door lock device configured as described above, the one-motion lever 53 attached to the inner handle lever 50 by the opening door operation by the inside handle 5 moves the link lever 40 from the locked position (see FIG. 11-1) to the unlocked position (FIG. 11-2). The one-motion link 56 attached to the inner handle lever 50 transmits the opening door operation by the inside handle 5 to the ratchet lever 25. Thereby, a so-called one-motion function can be realized. Further, the opening door operation by the inside handle 5 is transmitted to the ratchet lever 25 via the one-motion link 56 regardless of the link lever 40. Thereby, the timing at which the link lever 40 is displaced from the locked position to the unlocked position and the timing at which the one-motion link 56 transmits the opening door operation by the inside handle 5 to the ratchet lever 25 can be arbitrarily set. As a result, even with a door lock device having a so-called one-motion function, the unlock timing and the door opening timing can be set in consideration of the operational feeling.

  Further, the link lever 40 can be reliably displaced from the locked position to the unlocked position by the opening door operation by the inside handle 5, while the opening door operation can be reliably transmitted to the ratchet lever 25 by the one motion link 56. Thereby, the locked state of the lock mechanism 600 is released, but there is no possibility that the opening door operation by the inside handle 5 is not transmitted to the ratchet lever 25.

  Hereinafter, the key lever 610 in the door lock device described above will be described in detail. FIG. 12 shows the key lever and the bearing hole.

  As shown in FIG. 12A, the input shaft portion 611 of the key lever 610 is formed by extending the shaft portion 611b integrally with the rotation base portion 611a.

The locking piece 617a is provided in a cantilever manner in which the base end is connected via an elastic portion 617b to the position of the opening edge of one side groove groove 616 where the bottom of the groove 616 continues. A contact piece 617c extends in the middle of the locking piece 617a. The abutting piece 617c is a cantilever in which the base end is connected to the locking piece 617a via an elastic portion 617d that is harder and has higher elastic force than the elastic portion 617b, and toward the outside of the locking piece 617a. It extends diagonally. The contact piece 617c is arranged such that, when the locking piece 617a is inserted into the concave groove 616, the free end is in the concave groove 616 and extends toward the distal end side of the shaft portion 611b.

  Further, the above-described lever portion 613 is provided on the outer peripheral portion of the rotation base 611a so as to extend in the radially outward direction of the rotation base 611a.

  The key lever 610 is configured such that the rotation recess 612 is fitted into the projection 302 formed in the sub case 3 and the shaft portion 611b is fitted into the bearing hole 202 formed in the main case 2 so that the input shaft portion 611 is inserted into the main case. 2 and the sub case 3 are rotatably supported inside the housing 10. The convex portion 302 and the bearing hole 202 are provided at a position below the housing 10, and the input shaft portion 611 is disposed at a position below the housing 10. Further, as shown in FIG. 4, the input shaft portion 611 is disposed at a position below electrical components such as the switch 628, the switch 637, and the drive motor 673 provided in the housing 10. As shown in FIGS. 2 and 4, a drain hole 100 is formed in the lower portion of the housing 10 provided with the input shaft portion 611. The drain hole 100 is a hole communicating with the inside and outside of the housing 10 and is provided on the main case 2 side in this embodiment. Note that the drain hole 100 may be provided on the side of the sub case 3 as long as it is opened in the lower portion of the housing 10, or may be provided in a manner straddling the main case 2 and the sub case 3.

  The bearing hole 202 is formed so as to penetrate outside the housing 10. As shown in FIG. 12A, the bearing hole 202 has an inner diameter that is inserted into the shaft portion 611b of the input shaft portion 611 and is rotatably supported. The bearing hole 202 has a cylindrical portion 203 at an opening edge facing the inside of the housing 10. Similar to the bearing hole 202, the cylindrical portion 203 has an inner diameter that is inserted into the shaft portion 611b of the input shaft portion 611 and is rotatably supported. Further, the cylindrical portion 203 is provided with a notch groove 203a. The notch groove 203 a is provided in a portion of the cylindrical portion 203 facing each other at the end edge facing the inside of the housing 10, and communicates with the concave groove 616 when the shaft portion 611 b is inserted into the bearing hole 202.

  The concave groove 616 and the cutout groove 203a communicate with each other when the input shaft portion 611 is at a predetermined rotational position. Here, the predetermined rotational position of the input shaft portion 611 will be described. When the key cylinder KC is locked, the input shaft portion 611 rotates counterclockwise in FIG. 8 to bring the lock mechanism 600 into the locked state. On the other hand, when the key cylinder KC is unlocked, the input shaft portion 611 rotates clockwise in FIG. 8 to bring the lock mechanism 600 into an unlocked state. In the key cylinder KC, the key insertion port exposed to the outside of the vehicle compartment is always in a predetermined position, and the key insertion direction into the key insertion port is always the same to facilitate key operation. The predetermined rotation position of the input shaft portion 611 corresponds to the predetermined position of the key insertion port of the key cylinder KC, and is substantially the center of the rotation in the above-described rotation operation, and the key cylinder KC is rotated by the key operation. When transmitted to the input shaft portion 611, both of the rotational movement amounts are neutral positions where they are substantially the same.

  Moreover, the bearing hole 202 has the latching cylinder 204 in the opening edge which faces the outer side of the housing 10, as shown in FIG.1, FIG.2 and FIG.12-2.

Moreover, the latching protrusion 204b is each provided in the inner wall in the latching cylinder 204 of each elastic piece 204a. The locking projection 204b has a locking surface 204ba formed flat toward the distal direction and the proximal direction of the locking cylinder 204.

  As shown in FIG. 1, key cylinder linking means 615 extending from a key cylinder KC provided in the door D is inserted into the bearing hole 202 from the outside of the housing 10.

  As shown in FIG. 12-2, the rotation operation when the key cylinder KC is locked or the key cylinder KC is unlocked at the tip of the key cylinder linkage means 615 inserted through the bearing hole 202. An output shaft 618 for transmitting the signal to the input shaft portion 611 is provided.

  The output shaft 618 is connected to the key cylinder KC and is formed in the shape of a longitudinal hook. The output shaft 618 has a long plate-like (for example, substantially single-letter cross-sectional shape) tip portion that engages with the concave groove 616 of the shaft portion 611b. ing. The output shaft 618 is housed in the outer cylinder 619. That is, the rotation of the key cylinder KC due to the key operation is transmitted to the input shaft portion 611 by rotating the output shaft 618 inside the outer cylinder 619. In addition, a tip portion of the outer cylindrical body 619 is formed with an inclined portion having a gradually increasing diameter toward the base end side, and a bearing hole 202 is formed on the outer periphery of the outer cylindrical body 619 on the base end side of the inclined portion. A locking groove 619a that fits into a locking projection 204b provided on each elastic piece 204a of the locking cylinder 204 is provided. The locking groove 619a has an inner shape that makes contact with the locking surface 204ba of the locking projection 204b. Then, the outer cylinder 619 is inserted into the locking cylinder 204, and the locking groove 619a and the locking projection 204b are engaged with each other, whereby the output shaft 618 is prevented from coming off from the bearing hole 202, and The state where the distal end portion of the output shaft 618 extending from the distal end portion of the outer cylindrical body 619 is engaged with the concave groove 616 in the shaft portion 611b of the input shaft portion 611 is maintained.

  Hereinafter, the operation | movement concerning engagement with the input shaft part 611 and the output shaft 618 is demonstrated with reference to FIGS. 12-2 to 12-5. 12-2 to 12-4 are cross-sectional views cut in a direction along the recessed groove 616 and the notch groove 203a, and FIG. 12-5 is cut in a direction perpendicular to FIGS. 12-2 to 12-4. FIG.

  First, as shown in FIG. 12B, the input shaft portion 611 is inserted through the bearing hole 202. In order to insert the input shaft portion 611 into the bearing hole 202, the elastic portion 617b is bent so that the locking piece 617a of the locking member 617 is placed in the concave groove 616. Then, the shaft portion 611b is inserted into the bearing hole 202 in this state. Further, the concave groove 616 is communicated with the notch groove 203 a of the cylindrical portion 203 in the bearing hole 202, and the rotating base portion 611 a is brought into contact with the edge of the cylindrical portion 203. Thereby, the locking piece 617a is positioned in both the concave groove 616 and the notch groove 203a, and is inserted into the notch groove 203a while being inserted into the concave groove 616. As a result, the locking piece 617a maintains the state in which the concave groove 616 and the cutout groove 203a communicate with each other, so that the input shaft portion 611 is locked at a predetermined rotational position and its rotation is restricted. In the above state, the contact piece 617c is elastically protruded from the locking piece 617a in the opening direction of the tip of the concave groove 616 via the elastic portion 617d.

  Next, as illustrated in FIG. 12C, the output shaft 618 is inserted into the bearing hole 202 from the outside of the housing 10 through the locking cylinder 204. The distal end portion of the output shaft 618 engages with the concave groove 616 of the input shaft portion 611 and pushes the contact piece 617c of the locking member 617 into the bottom side of the concave groove 616. At this time, in the locking member 617, since the elastic portion 617d at the base end of the contact piece 617c is harder than the elastic portion 617b at the base end of the locking piece 617a, only the elastic portion 617b is bent and the locking piece 617a is bent. Is pushed into the bottom of the groove 616. As a result, the locking piece 617a is pushed out from the notch groove 203a, the locking of the input shaft portion 611 is released, and the rotation is allowed. In addition, the outer cylinder 619 that houses the output shaft 618 is inserted into the locking cylinder 204. At this time, the locking protrusion 204b abuts on the oblique portion of the distal end of the outer cylinder 619, so that the locking cylinder 204 The elastic piece 204 a having the protrusion 204 b bends in the radially outward direction of the locking cylinder 204. In the state of FIG. 12C, since the output shaft 618 is already engaged with the concave groove 616 of the input shaft portion 611, the input shaft portion 611 rotates as long as there is no transmission of rotation from the output shaft 618. There is nothing.

  Finally, as shown in FIGS. 12-4 and 12-5, the output shaft 618 is further inserted toward the bottom of the concave groove 616. At this time, the elastic piece 204a of the locking cylinder 204 returns to its original position by its own elasticity, and the locking groove 619a provided in the outer cylinder 619 and the locking projection 204b provided in the locking cylinder 204 are engaged with each other. Match. Accordingly, the output shaft 618 is prevented from coming off from the bearing hole 202, and the engagement of the output shaft 618 with the concave groove 616 of the input shaft portion 611 is maintained. At this time, the abutting piece 617 c of the locking member 617 is further pushed into the bottom of the concave groove 616 by the tip of the output shaft 618. Since the locking piece 617a reaches the bottom of the concave groove 616, the contact piece 617c is configured such that the elastic portion 617d is bent and the locking piece 617a is further pushed into the concave groove 616.

  The key lever 610 described above rotates only when the key cylinder KC is key-operated, and switches the lock mechanism 600 to a locked state or an unlocked state. Specifically, the turning operation of the key lever 610 is transmitted to the key sub lever 620 via the key link 627, and the connect lever 630 is rotated around the convex portion 302. Further, the rotation operation of the key lever 610 is transmitted to the key sub lever 620 via the key link 627, and the lock lever 640 is rotated around the rotation shaft portion 635, and the inside lock is performed via the lock button linking means 642. Set button 6 to the unlocked / unlocked state. However, the lock operation of the inside lock button 6 and the rotation operation of the sector gear 650 are not transmitted to the key lever 610. In order to realize transmission of this operation, in the door lock device, an idling region is provided between the key sub lever 620 and the connect lever 630.

  The key lever 610 moves the input shaft portion 611 to a predetermined rotational position (neutral position) until the output shaft 618 and the input shaft portion 611 are engaged by the positioning means including the concave groove 616, the cutout groove 203a, and the locking member 617. When the output shaft 618 and the input shaft portion 611 are engaged, the input shaft portion 611 is allowed to rotate. That is, it is possible to prevent the input shaft portion 611 from rotating within the above-described idling region before the output shaft 618 is engaged with the input shaft portion 611. As a result, when the rotation of the key cylinder KC by the key operation from the outside is transmitted to the lock mechanism 600 as a rotational driving force, the rotation range of the input shaft portion 611 to the unlocked state or the locked state is not biased.

  Therefore, in the door lock device configured as described above, an input unit that inputs a driving force from the outside of the housing 10 and switches the lock mechanism 600 between the unlocked state and the locked state is disposed at a position below the housing 10. is there. In this embodiment, the input unit is the input shaft unit 611 of the key lever 610 that inputs the rotational driving force from the key cylinder KC by a key operation. That is, since the input shaft portion 611 is disposed at a position below the housing 10, rainwater or the like attached to the key cylinder KC or the window glass disposed in the door D travels through the key cylinder linking means 615 to the input shaft portion 611. However, the rainwater does not reach each mechanism inside the housing 10. As a result, each mechanism housed in the housing 10 does not cause malfunction. In particular, since the input shaft portion 611 is disposed at a position below the electrical component, malfunction of the electrical component is prevented. Furthermore, since the drain hole 100 is provided in the lower part of the housing 10, rainwater that has entered the inside of the housing 10 is discharged to the outside of the housing 10.

  In addition, as an input unit that inputs a driving force from the outside of the housing 10 and switches the lock mechanism 600 between an unlocked state and a locked state, a lock lever 640 for inputting a driving force by operating the inside lock button 6 is fixed. There is also a pivot shaft 635. In the present embodiment, the rotation shaft portion 635 is disposed at a relatively lower position of the housing 10 below the electrical component provided inside the housing 10. That is, by arranging the rotation shaft portion 635 at a position below the housing 10, rainwater or the like adhering to the window glass disposed in the door D can reach the rotation shaft portion 635 through the lock button link means 642. The rainwater does not reach each mechanism inside the housing 10. As a result, each mechanism housed in the housing 10 does not cause malfunction. In particular, since the rotation shaft portion 635 is disposed at a position below the electrical component, malfunction of the electrical component is prevented. Furthermore, since the drain hole 100 is provided in the lower part of the housing 10, the rainwater that has entered the housing 10 is discharged to the outside of the housing 10.

  As described above, the door lock device according to the present invention includes a lock mechanism in a housing, and is useful for a configuration in which the lock mechanism is switched between an unlocked state and a locked state by a driving force from the outside of the housing. In particular, it is suitable for preventing rainwater that can enter the inside of the apparatus from affecting the internal mechanism of the apparatus.
