As shown in FIG. 7 (a), the end surface of the operation member storage portion 3B of the base member 3 engages with the second slider 18 so that the handle slider side transmission lever 13 side of the second slider 18 (FIG. 7 ( A restricting portion 3i that restricts a predetermined or more movement to the right of a) is configured.

  Next, the operation of the door lock device 1 according to the present invention configured as described above will be described below with reference to FIGS.

  8 is a rear view showing an unlocked state of the door lock device, FIG. 9 is a rear view showing a state where the inner handle is operated from the unlocked state of the door lock device, and FIG. 10 shows a locked state of the door lock device. FIG. 11 is a rear view showing a state where the inner handle is operated from the locked state of the door lock device, and FIG. 12 is a rear view showing a state where the front door is opened in the locked state of the door lock device.

  When the front door 52 shown in FIGS. 1 and 2 is in an open state (unlocked state) and the rear door 53 is in a closed state (locked state), in the door lock device 1, the contact portion 17B of the first slider 17 is the front door. As shown in FIGS. 7 (a) and 8 (indicated by a chain line in FIG. 2), the projection protrudes outward to be separated from 52. At this time, since the operating member 5 is in the left limit position in FIG. 8, the operation portion 18 c of the second slider 18 is separated from the handle side transmission lever 13. For this reason, the handle side transmission lever 13 is moved to the coupling position by the urging force of the spring 16, and at this time, the engaging portion 12 d of the latch side transmission lever 12 is the step of the guide groove hole 13 b of the handle side transmission lever 13. The latch side transmission lever 12 and the handle side transmission lever 13 are in a connected state by engaging with the portion 13b2.

  When the occupant pulls the inner handle 2 from the state shown in FIG. 8 toward the back side of the page of FIG. 9 and rotates it around the support shaft 6, the rotation of the inner handle 2 causes the rotation of the rotary lever 10. The handle-side transmission lever 13 connected to the rotary lever 10 is moved upward as converted into motion. Then, the step portion 13b2 of the guide groove 13b of the handle side transmission lever 13 is engaged with the engagement portion 12d of the latch side transmission lever 12, and the latch side transmission lever 12 is coiled around the screw 14 (see FIG. 5). 9), the control cables 60 and 61 connected to the first connecting portion 12b and the second connecting portion 12c of the latch-side transmission lever 12 are pulled together. Accordingly, the upper and lower latch units 58 and 59 (see FIG. 1) are operated to release the lock on the rear door 53 and allow the rear door 53 to be opened.

  Next, when the rear door 53 is closed and closed, and the opened front door 52 is closed and closed, the inner panel 52b of the front door 52 is moved to the first slider 17 as shown by a solid line in FIG. The abutting portion 17B is abutted and pressed. At this time, since the urging force of the first spring 19 is set smaller than the urging force of the second spring 20 in the operating member 5 as described above, as shown in FIG. 17 is pressed to the right side of the figure, the second spring 20 is not compressed, only the first spring 19 is compressed, and the first slider 17 and the second slider 18 move integrally in the right direction of the figure. When the operation of the inner handle 2 is released, the inner handle 2 is rotated toward the initial position by the biasing force of the spring 9, and the rotation lever 10 is interlocked with the rotation of the inner handle 2. The handle side transmission lever 13 is rotated downward to return to the state before the occupant operates the inner handle 2 (the state shown in FIG. 8).

  As shown in FIG. 7B, when the right end of the second slider 18 comes into contact with the restricting portion 3i formed in the operating member storage portion 3B of the base member 3, the operation portion 18c of the second slider 18 is illustrated. 10, the handle side transmission lever 13 abuts against the urging force of the spring 16 against the handle side transmission lever 13 (the engaging portion 12 d of the latch side transmission lever 12 is connected to the handle side transmission lever 13. The guide groove hole 13b is moved to a position engaging with the long hole portion 13b1.

  Thereafter, the first slider 17 is set to move by a predetermined distance while compressing the second spring 20. For this reason, even if the distance between the front door 52 and the first slider 17 varies depending on the component accuracy, the variation is absorbed by the movement of the first slider 17. That is, even if the dimensional accuracy between the front door 52 and the first slider 17 is shifted in the horizontal direction in the range of a and b shown in FIG. 7B, the second slider 18 is reliably moved to a predetermined position. Damage to parts due to excessive movement of the second slider 18 is prevented.

  Since the front door 52 is closed and the latch side transmission lever 12 and the handle side transmission lever 13 of the door lock device 1 are not connected as shown in FIG. When it is pulled to the side and rotated about the support shaft 6, the rotational movement of the inner handle 2 is converted into the rotational movement of the rotary lever 10, and the handle side connected to the lower end of the rotary lever 10 The transmission lever 13 moves upward.

  However, the engaging portion 12d of the latch-side transmission lever 12 simply moves within the elongated hole portion 13b1 of the guide groove 13b of the handle-side transmission lever 13, and the operating force of the handle-side transmission lever 13 is changed to the latch-side transmission lever 12. Since the latch side transmission lever 12 does not rotate and the latch units 58 and 59 do not operate, the rear door 53 is locked and the rear door 53 cannot be opened.

  Until the front door 52 is opened, even if the occupant operates the inner handle 2, the rear door 53 cannot be opened. However, if the front door 52 is opened while the inner handle 2 is operated, the front door 52 cannot be opened. Since the pressing on the operating member 5 by the door 52 is released, the operating member 5 protrudes outward (in the direction of the arrow in the drawing) as shown in FIG. At this time, the handle side transmission lever 13 moves in the direction of the coupling position because the engaging portion 12d of the latch side transmission lever 12 is located in the elongated hole portion 13b1 of the guide groove hole 13b of the handle side transmission lever 13. However, since the actuating member 5 and the handle side transmission lever 13 are configured to be separable, only the actuating member 5 is left in FIG. 12 by the urging force of the first spring 19. Move in the direction.
