  That is, for example, when a large external input such as a collision load is applied, in the extending direction of the striker 21 (the engaging shaft portion 21c) that engages with the latch 35, that is, in the direction along the support shaft 33 of the latch 35. A relative displacement may occur between the striker 21 provided on the vehicle body side and the door lock device 20 provided on the back door 10 side. The door lock device 20 according to the present embodiment is configured to receive the input load at this time by a resin guide 50 in contact with the striker 21 and a guide plate 51 as a guide member that supports the resin guide 50.

  Further, the door lock device 20 of the present embodiment has a structure in which the guide plate 51 is connected to the base plate 31 and the sub base 32 that constitute the support member of the latch 35. That is, the load input to the guide plate 51 is distributed to the base plate 31 and the sub-base 32 through the connection portion. The door lock device 20 of the present embodiment is configured to improve its reliability by increasing the overall strength including the guide plate 51, the base plate 31, and the sub-base 32.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The door lock device 20 includes a resin guide 50 as a guide portion into which the striker 21 enters and exits based on an opening / closing operation of the back door 10, and a guide member that supports the resin guide 50 and is fixed to the back door 10. A guide plate 51. Further, the door lock device 20 engages with the striker 21 that has entered the resin guide 50 and rotates to lock the striker 21 so that the striker 21 cannot be detached, and the latch 35. The base plate 31 and the sub base 32 are provided as support members that are rotatably supported by the back door 10. The guide plate 51 has a pair of opposing walls 61 and 62 facing each other with a spread that intersects the axial direction of the support shaft 33 that constitutes the rotation shaft of the latch 35, and between these opposing walls 61 and 62. The resin guide 50 is supported at a position surrounded by the opposing walls 61 and 62 and the connection wall 63. The base plate 31 has a connection portion with respect to the connection wall 63 and is coupled to the guide plate 51.

  According to the above configuration, for example, even when a large external input such as a collision load is applied, the input load is received by the resin guide 50 that contacts the striker 21 and the guide plate 51 that supports the resin guide 50. be able to. And thereby, high reliability can be ensured by reducing the load of the latch 35 engaged with the striker 21, the base plate 31, and the sub base 32.

  Here, the door lock device 20 is provided at the peripheral edge portion 10a (upper corner) of the back door 10, and the resin guide 50 is set at the outermost peripheral edge portion thereof. For this reason, it is difficult to secure a fixing space necessary for securing the sufficient support strength of the fixing portion 65 of the guide plate 51 that supports this to the back door 10. However, by adopting a configuration in which the input load received by the guide plate 51 is distributed to the base plate 31 and the sub-base 32 as described above, the load of the fixing portion 65 on the back door 10 can be reduced. As a result, the overall strength including the guide plate 51, the base plate 31, and the sub-base 32 can be increased.

  In particular, the input load applied to the guide plate 51 includes both opposing walls 61 having a spread in one axial direction of the relative displacement between the door lock device 20 and the striker 21, that is, in the axial direction of the support shaft 33 that serves as the rotation shaft of the latch 35. It will concentrate on one side of 62. However, as described above, by setting the connection location with the base plate 31 to the connection wall 63 extending in the axial direction of the support shaft 33, the input load to the guide plate 51 can be efficiently distributed to the base plate 31. . And thereby, higher reliability can be ensured by relaxing the concentration of stress on the specific part.

According to the above configuration, the connection wall 63 of the guide plate 51 and the base plate 31 can be reliably connected with a simple configuration. In addition, the input load to the guide plate 51 can be efficiently performed regardless of the direction of relative displacement between the door lock device 20 and the striker 21 along any of the support shafts 33 serving as the rotation shaft of the latch 35. Can be dispersed in the base plate 31. And thereby, higher reliability can be ensured.

(3) The sub-base 32 is provided with a support portion 73 that is juxtaposed with the second opposing wall 62 in the resin guide 50.
According to the above configuration, for example, when an external input is applied from the right side to the left side in FIG. 3 and the second opposing wall 62 is about to be deformed by an input load on the guide plate 51, the second opposing wall When the support portion 73 supports 62, the input load to the guide plate 51 can be distributed to the sub-base 32. And thereby, higher reliability can be ensured by relaxing the stress concentration on the second opposing wall 62. In addition, since there is a gap between the support portion 73 and the second opposing wall 62, there is an advantage that the resin guide 50 can be easily assembled to the guide plate 51.

  (4) The fixing portion 65 of the guide plate 51 is fastened together with the back door 10 together with the flange portion 32 b of the sub base 32. Thereby, the guide plate 51 and the sub base 32 can be more firmly connected with a simple configuration.

The door type is not necessarily a double-spread type, such as a so-called flip-up type. In the case of a double door, the door lock device 20 is usually provided at the peripheral corner of the vehicle door. For this reason, in many cases, the fixing portion 65 of the guide plate 51 cannot secure a fixing space necessary to ensure sufficient support strength. Therefore, a more remarkable effect can be obtained by using such a double door.

  In the above-described embodiment, the opposing walls 61 and 62 of the guide plate 51 are orthogonal to the axial direction of the support shaft 33 serving as the rotation axis of the latch 35, but have a spread that intersects the axial direction. If it is a thing, it does not necessarily need to be orthogonal.

  In the above embodiment, the guide member is configured by the base plate 31 and the sub base 32 as a pair of base members on which the support shaft 33 that constitutes the rotation shaft of the latch 35 is bridged. The base plate 31 is provided with a connection portion (fitting protrusion 72) to the connection wall 63, and the sub base 32 is formed with a support portion 73 juxtaposed with the second opposing wall 62. However, the present invention is not limited to this, and the sub base 32 may be provided with a connection portion for the connection wall 63. Moreover, the structure provided in both the base plate 31 and the sub base 32 may be sufficient. Further, the base plate 31 may be provided with a support portion disposed to face the first facing wall 61. And you may change arbitrarily also about the component of the support member.

  In the above embodiment, the connection wall 63 of the guide plate 51 is formed with the fitting hole 71, and the base plate 31 is formed with the fitting protrusion 72 that fits into the fitting hole 71. . However, the present invention is not limited to this, and the form of the connection portion with respect to the connection wall 63 is not necessarily limited to fitting, such as bonding, as long as the input load to the guide plate 51 can be distributed to the base plate 31. Good.

  In the above embodiment, the guide plate 51 as the guide member supports the resin guide 50 as the guide portion at a position surrounded by the opposing walls 61 and 62 and the connection wall 63. However, the present invention is not limited to this, and the material and shape of the guide portion may be arbitrarily changed.

  In the above embodiment, the latch 35 is urged to rotate based on the elastic force of the torsion coil spring. However, the urging member of the lock member may be arbitrarily changed. In addition, the latch mechanism 30 mechanically releases the lock of the striker 21 based on the operation input to the operation handle 45. However, for example, the release operation mode such as using the driving force of the electric actuator is arbitrary. You may change to
