Furthermore, since the fence block 25 is made of resin, the weight can be reduced and the weight can be further reduced as compared with the case where the metal set plate 38 is greatly extended and each component is disposed, for example. However, since the fork 44 and the claw lever 48 to which an excessive load is applied are rotatably supported by the metal base plate 36 and the set plate 38, it is possible to prevent the occurrence of malfunction.

  Further, in the first housing portion 12, a lock plate 57 and open levers 65 and 70 are disposed in the space at the end of the link 60. Therefore, the thickness of the first housing portion 12 including the opening mechanism 64 and the latch mechanism 43 can be reduced, and the door lock device 10 can be further downsized. Moreover, since the shaft support portions 33 and 34 of the open levers 65 and 70 having different axial directions of the rotation shafts are provided in the first housing portion 12, the number of parts can be reduced and the manufacturing cost can be reduced. In addition, since the second handle connecting portion 72 of the inner open lever 70 protrudes outward from the lower end of the first housing portion 12, water droplets or the like traveling along the connection cable 2 do not enter the housing 11. It can be dropped as it is. As a result, since it is not necessary to provide a waterproof cover or the like separately, the door lock device 10 can be reduced in size and weight can be reduced.

  In the second housing portion 13, since the drive motor 86 is disposed horizontally so that the output shaft 87 is positioned between the wheel gear 89 and the key lever 84, the switching mechanism 73 corresponds to the lock mechanism 53. It can be arranged in a concentrated position. Therefore, the second housing part 13 can be further reduced in size. Further, a switching lever 74 is disposed between the key lever 84 and the wheel gear 89, and manual and electric operations are integrated into one switching lever 74. Further, by configuring the lock mechanism 53 disposed on the inner surface side of the first housing portion 12 by the switching lever 74, the number of parts housed in the second housing portion 13 can be reduced, and the second housing portion 13 can be further downsized.

  The door lock device 10 of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made.

  For example, in the above-described embodiment, the release lever 54 that is connected to the claw lever 48 and rotates integrally as the lock mechanism 53 is provided, and the release lever 54 is operated by the link 60 so that the claw lever 48 is moved in the unlocking direction. However, the claw lever 48 may be provided with an operation receiving portion that penetrates the fence block 25 and the release lever 54 may not be provided.
