As shown in FIG. 11-2, the child pin support groove 42b of the child lever 42 is fitted into the mounting groove 46e formed from the base portion 46a, the mounting pin 46b, and the stopper portion 46d, thereby fitting the child. The pin 46 is mounted so as to be movable along the extending direction of the child pin support groove 42b. As shown in FIG. 11B, the transmission pin 46c is a columnar protrusion that extends substantially horizontally along the left-right direction of the vehicle main body B from the end surface of the base portion 46a located on the outdoor side. The transmission pin 46c passes through the pin accommodating hole 41c of the connect lever 41, and the protruding end portion thereof reaches a position exceeding the outdoor side end surface of the inhan lock linking portion 12b in the inside handle lever 12. Further, as shown in FIG. 1, the transmission pin 46 c is disposed in the swinging area of the inhan lock linking portion 12 b in the inside handle lever 12 when the manual operation portion 42 d of the child lever 42 is disposed in the first position. On the other hand, as shown in FIG. 2, when the manual operation portion 42d of the child lever 42 is disposed at the second position, the child lever 42 is disposed outside the swinging range of the inhan lock linking portion 12b.

  Further, as shown in FIG. 1, a power child pin 51 is inserted into the power child groove 42 e of the child lever 42. The power child pin 51 is a columnar protrusion that extends substantially horizontally along the left-right direction of the vehicle body B from the end surface of the power child lever 52 located on the indoor side. The power child pin 51 is configured to be movable along the extending direction of the worm 54 in accordance with the movement of the power child lever 52 when the worm 54 fixed to the output shaft 53a of the electric motor 53 rotates. .

  In the lock mechanism 30 configured as described above, the state shown in FIG. 1 is an unlocked state, and the ratchet drive portion 33d of the link lever 33 is disposed vertically above the mounting hole 33b. The ratchet lever 26 is in close proximity to the lower end surface of the contact portion 26a. Accordingly, when the outside door handle ODH is opened from this state and the link main body 33a of the link lever 33 is moved upward by the rotation of the open lever 11, the ratchet driving portion 33d is brought into contact with the ratchet lever 26 in the latch mechanism 20. This abuts on the contact portion 26a and moves it upward. As a result, even when the latch mechanism 20 is in the latched state, this is released, so that the door D can be opened and moved with respect to the vehicle body B.

  When the worm wheel 31 is rotated counterclockwise by driving the electric motor 35 from the unlocked state shown in FIG. 1, the sector lever 32 swings clockwise about the sector lever shaft 38. As a result, in the lock mechanism 30, the link lever 33 linked via the connecting pin 32a and the panic lever 39 swings counterclockwise about the mounting hole 33b, and the lock mechanism 30 enters the locked state shown in FIG.

  In this locked state, the ratchet driving portion 33d deviates from the position facing the lower end surface of the abutting portion 26a of the ratchet lever 26, so that the outside door handle ODH is opened and the link lever is rotated by the rotation of the open lever 11. Even when the link body 33 a of 33 is moved upward, the ratchet driving portion 33 d does not contact the contact portion 26 a of the ratchet lever 26 in the latch mechanism 20. As a result, when the latch mechanism 20 is in the latched state, this is maintained, so that the door D is maintained at the closed position with respect to the vehicle body B.

  By the way, in this locked state, the transmission pin 46c of the child pin 46 is disposed in the swinging area of the inside lock lever 12b in the inside handle lever 12. When the inside door handle IDH is operated to open from this state, the in-han lock linkage portion 12b moves the transmission pin 46c downward, and the sector lever contact portion 12c contacts the inside handle lever of the sector lever 32. The part 32c is moved toward the rear of the vehicle. When the transmission pin 46c moves downward, the connect lever 41 through which the transmission pin 46c penetrates swings counterclockwise in FIG. 12, and its transmission end 41b moves upward, so that the pressure receiving portion 11b of the open lever 11 is moved. As a result, the link lever 33 is also moved upward. On the other hand, when the inside handle lever abutting portion 32c moves to the rear of the vehicle, the sector lever 32 swings counterclockwise in FIG. 12, and the connecting pin 32a moves to the rear of the vehicle. It will swing clockwise. At this time, as shown in FIG. 13, the ratchet drive portion 33d of the link lever 33 comes into contact with the contact portion 26a of the ratchet lever 26 from the front side of the vehicle, so that the panic lever 39 is moved to a panic spring (not shown). ) Is released from the contact state with the panic lever contact portion 33c of the link lever 33 against the elastic restoring force, and swings clockwise in FIG.

  When the door opening operation force of the inside door handle IDH is removed from this state, the link lever 33 again positions the panic lever contact portion 33c in the panic lever 39 forward of the vehicle by the elastic restoring force of the panic spring (not shown). The moving end portion 11a and the pressure receiving portion 11b are moved downward by the elastic restoring force of an open lever spring (not shown). When the operating end portion 11a and the pressure receiving portion 11b move downward, the transmission end portion 41b of the connect lever 41 moves downward via the pressure receiving portion 11b of the open lever 11 as shown in FIG. The transmission pin 46c is disposed in the swing range of the in-han lock linking portion 12b in the inside handle lever 12. On the other hand, when the panic lever abutting portion 33c of the link lever 33 moves so as to abut on the end surface located in front of the vehicle in the panic lever 39, as shown in FIG. 14, the ratchet driving portion 33d of the link lever 33 is attached to the mounting hole 33b. Therefore, the ratchet driving portion 33d is close to and opposed to the lower end surface of the contact portion 26a of the ratchet lever 26, and the lock mechanism 30 is unlocked. If the inside door handle IDH is operated to open in this state, the in-han lock linking part 12b moves the transmission pin 46c downward. When the transmission pin 46c moves downward, the connect lever 41 through which the transmission pin 46c penetrates swings counterclockwise in FIG. 14, and its transmission end 41b moves upward, so that the pressure receiving portion 11b of the open lever 11 is moved. As a result, the link lever 33 is also moved upward. Accordingly, as shown in FIG. 15, the link lever 33 comes into contact with the contact portion 26a of the ratchet lever 26 in the latch mechanism 20, and the latched state can be released. That is, the door D can be opened and moved by the opening operation of the inside door handle IDH (so-called double action mechanism).

  When the worm wheel 31 is rotated clockwise by driving the electric motor 35 from the locked state shown in FIG. 12, the sector lever 32 swings counterclockwise about the sector lever shaft 38. As a result, in the lock mechanism 30, the link lever 33 linked via the connecting pin 32a and the panic lever 39 swings clockwise around the mounting hole 33b, and returns to the unlocked state shown in FIG.

  Further, in the child lock mechanism 40 configured as described above, the state shown in FIGS. 1 and 16 is the transmission state. In the transmission state, the transmission pin 46c of the child pin 46 is arranged in the swinging area of the inner lock linkage portion 12b in the inside handle lever 12. When the inside door handle IDH is operated to open from this state, the in-han lock linkage portion 12b moves the transmission pin 46c downward. When the transmission pin 46c moves downward, the connect lever 41 through which the transmission pin 46c penetrates swings counterclockwise in FIGS. 1 and 16, and the transmission end 41b moves upward. The link lever 33 also moves up via the pressure receiving part 11b. Therefore, when the lock mechanism 30 is in the unlocked state, the link lever 33 comes into contact with the contact portion 26a of the ratchet lever 26 in the latch mechanism 20, and the latched state can be released. That is, the door D can be opened and moved by the opening operation of the inside door handle IDH.

  On the other hand, the child lock manual operation portion 42d of the child lever 42 is slid downward from the first position shown in FIGS. 1 and 16 so as to draw an arc around the axis of the vehicle body B in the left-right direction. Then, when moved to the second position shown in FIGS. 2 and 17, the child lever 42 swings clockwise around the child lever shaft 10b in FIGS. 1 and 16, and the child lever 42f is connected to the child lever 42f. The shaft 43 is arranged. In this state, the child lock mechanism 40 is in a non-transmitting state. In this non-transmission state, the transmission pin 46c of the child pin 46 is disposed outside the swinging range of the inhan lock linking portion 12b in the inside handle lever 12, so that even if the inside door handle IDH is operated to open, the inhan lock linking portion 12b. And the transmission pin 46c do not come into contact with each other, and the connect lever 41 does not swing. As a result, the door D cannot be opened and moved by the opening operation of the inside door handle IDH.

  In the door lock device including the lock mechanism 30 and the child lock mechanism 40 as described above, the lock mechanism 30 can be easily switched between the locked state and the unlocked state by driving the electric motor 35 during normal use. it can.

  On the other hand, when the electric motor 35 is not driven due to a failure in the electric motor 35 or a charging voltage of a battery (not shown) being lowered, the emergency lock of the rotating member 60 is started from the state where the door D is opened. A tool or key may be inserted into the groove 60c of the manual operation unit 60a, and the emergency lock manual operation unit 60a may be rotated clockwise from the position shown in FIG. As a result, the contact surface 33g is pressed by the lock lever contact portion 60b of the rotating member 60 and the link lever 33 swings, and the lock mechanism 30 is switched to the locked state shown in FIGS. Therefore, even if the above-mentioned state occurs when the indoor lock operation member is omitted, the vehicle can be secured.

  Further, the child lock manual operation section 42d and the emergency lock manual operation section 60a are provided at positions that are closed when the door D is closed, as shown in FIGS. Therefore, even if a malicious object breaks the window glass, it is difficult to operate the child lock manual operation unit 42d and the emergency lock manual operation unit 60a. Accordingly, even when the lock mechanism 30 is switched from the locked state to the unlocked state by operating the inside door handle IDH to improve the operability, the child lock manual operation unit 42d is operated. If the child lock mechanism is set to the non-transmission state, the latch state of the latch mechanism 20 is not released by the opening operation of the inside door handle IDH.

Further, FIG. 19-3 shows the state shown in FIG. 18, that is, the child lock manual operation unit 42d is arranged at the second position (child lock ON), and the emergency lock manual operation unit 61 is operated and locked. The state where the mechanism 30 is switched to the locked state (emergency lock ON) is shown. In the above description, the emergency lock manual operation unit 60a is operated when the child lock is ON (non-transmission state), but the emergency lock manual operation unit 60a is operated when the child lock is OFF (transmission state). Of course, the lock mechanism 30 can be switched to the locked state.

  As described above, according to the door lock device of the present embodiment, the child lock manual operation unit 42d and the emergency lock manual operation unit 60a are provided independently on the same surface, and further, By providing the panel DP with displays corresponding to the operation positions of the manual operation unit 42d and the emergency lock manual operation unit 60a, the manual operation unit for emergency lock is erroneously operated when the child lock manual operation unit 42d is operated. It is possible to reliably prevent an erroneous operation such as operating the operation unit 60a.

  Note that the transition from the transmission state to the non-transmission state of the child lock mechanism 40 is not necessarily performed by operating the child lock manual operation unit 42d, and the electric motor 53 can be operated during normal use from the state shown in FIG. It may be driven. When the electric motor 53 is driven, the power child lever 52 moves forward along the extending direction of the worm 54 via the output shaft 53 a and the worm 54. When the power child lever 52 moves forward of the vehicle, the child lever 42 is disposed at the second position via the power child pin 51, and the child lock mechanism 40 is in a non-transmitting state.
