That is, the operating force from the inside door handle can be transmitted to the pole 24 at all times.

  Further, the inside door handle connecting member 80 and the rotation output board 61 are engaged with each other by an uneven engagement portion (not shown), and when the inside door handle connection member 80 rotates, the rotation output board is associated therewith. 61 also rotates. And the rotation output board 61 is connected with the connection switching member 35 via the 1st locking lever 41, the 2nd locking lever 42, and the lever connection spring between them. Accordingly, when the inside door handle is operated in the locked state, the connection switching member 35 is automatically changed from the locked posture to the unlocked posture.

  This completes the description of the configuration of the vehicle door lock device 20 of the present embodiment. Next, the function and effect of the vehicle door lock device 20 will be described. In this vehicle door lock device 20, the connection switching member 35 is changed between a lock posture and a lock release posture by operation of a lock operation unit such as a key cylinder or a lock operation switch provided in the door 10. When the connection switching member 35 is in the unlocked posture, when the outside door handle of the door 10 is operated, the operating force is transmitted to the pole 24 via the connection switching member 35 and the pole integrated rotation member 30. The pole 24 moves to the latch release position, the latch 23 rotates, and the door 10 is opened.

  On the other hand, when the connection switching member 35 is in the locked posture, the connection switching member 35 and the pole integral rotation member 30 are disconnected, and even if the outside door handle is operated, the operation force is transmitted to the pole 24. First, the pole 24 is held at the latch restricting position and the latch 23 is also held at the latch position. As a result, the door 10 is locked.

  Here, in the vehicle door lock device 20 of the present embodiment, the inside door handle connecting member 80 is connected to the inside door handle, and the operation force from the inside door handle is transmitted to the relay link 81 and the pole integrated rotating member 30. Therefore, even if the connection switching member 35 is in the locked posture, the door can be easily operated from the inside of the vehicle by operating the inside door handle without performing the unlocking operation separately. Can be opened.

  In this embodiment, the connection lever 46 connected to the key cylinder among the external operation lock members 43 for changing the connection switching member 35 between the lock posture and the lock release posture is substantially parallel to the end surface of the door 10. Since it has a rotating shaft and extends substantially parallel to the side surface of the door 10, even if the connecting lever 46 is lengthened, the connecting lever 46 remains on the side surface of the door 10 (see the portion indicated by reference numeral 11C in FIG. 1). Do not approach. Thereby, the installation space of the vehicle door lock device 20 can thereby be made compact.

  Further, for example, even if the operating resistance of the connection switching member 35 increases due to grease breakage or the like, the inside door handle connection member 80 is made independent of the connection switching member 35 while elastically deforming the lever connection spring when the inside door handle is operated. Therefore, the door 10 can be opened with a light operation of the inside door handle.
