  In addition, in this embodiment, although the example which attaches the striker 4 to the location corresponding to the upper part of the door 2 is demonstrated, it replaces with this and may attach to the location corresponding to the lower part or side part of the door 2. good. Alternatively, the door latch device 3 may be attached to the vehicle body 1 and the striker 4 may be attached to the door 2. When the striker 4 is attached to a portion corresponding to the lower part of the door 2, the upside down is performed. Moreover, when attaching to the location corresponding to a side part similarly, the left-right direction becomes an up-down direction.

  As shown in FIGS. 3 to 15, the striker 4 includes a base member 41 that is integrally formed by pressing an iron plate or other metal plate and fixed to a reinforcement (attached portion) 5 at the rear upper part of the vehicle body 1. And an engaging bar 42 formed by bending an iron bar having a portion fixed to the base member 41 and engaged with the door latch device 3. Moreover, the cover 7 for concealing the welding part to the base member 41 of the engagement rod 42 and improving appearance is attached to the base member 41 as needed.

  The base member 41 is bent in the opposite direction to the reinforcement 5 at the attachment portion 411 fixed to the reinforcement 5 with two bolts 6 on the left and right, and the rear end (left end in FIGS. 8 and 9) of the attachment portion 411. A welded portion 412, and a flange portion 413 that is connected to the lower end of the welded portion 412, is substantially perpendicular to the welded portion 412, and faces obliquely downward in the front direction.

  The attachment portion 411 is provided with two attachment holes 411a into which the bolts 6 are inserted, and a raised portion 411b that protrudes downward to increase the rigidity of the attachment portion 411.

  On the front surface of the welded portion 412, three pieces project forward from the reference surface (the front surface of the welded portion 412) and extend along the longitudinal (axial) direction of a leg portion 421 described later of the engagement rod 42. Ridges 414 and ridges 414a protruding forward in a substantially rectangular shape in front view are provided. The raised portion 414 is formed so as to be continuous with the raised portion 411b of the attachment portion 411.

  The flange portion 413 is provided with through holes 415 and 415 into which both the leg portions 421 of the engagement rod 42 are inserted. Note that the hole size of the through hole 415 is set to be approximately equal to or slightly larger than the diameter of the leg portion 421 of the engagement rod 42.

  The engagement rods 42 are respectively connected to the left and right leg portions 421 that are welded in parallel to the front surface of the welded portion 412 and the lower ends of both leg portions 421, and rearward (in the direction facing the closing direction C of the door 1). The left and right extending portions 422 extend, and the rear ends of the extending portions 422 are connected to each other, and the engaging portion 423 that faces the left and right directions with which the door latch device 3 can engage is provided.

  The right leg portion 421 is welded to the front surface of the welded portion 412 while being inserted into the right through hole 415 and installed between the left and right raised portions 414. Thus, the left and right raised portions that have the effect of increasing the rigidity of the welded portion 412 while the welded portion of the right leg 421 to the front surface of the welded portion 412 protrudes from the reference surface of the front surface of the welded portion 412. Therefore, the right leg portion 421 can be firmly welded to the front surface of the welded portion 412. Further, the left leg portion 421 is welded to the front surface of the welded portion 412 while being inserted into the left through-hole 415 and installed between the raised portion 414 and the raised portion 414a. Thereby, the welded portion of the left leg portion 421 to the front surface of the welded portion 412 also protrudes from the reference surface of the front surface of the welded portion 412 and has the effect of increasing the rigidity of the welded portion 412, Since it becomes 414a, the left leg part 421 can be firmly welded to the front surface of the welded part 412. Therefore, both the leg portions 421 of the engagement rod 42 can be firmly welded to the base member 41. Note that the raised portions 414 and 414a also function as alignment of the leg portion 421 with respect to the welded portion 412 and improve workability.

  Further, both the leg portions 421 of the engagement rod 42 are welded to the front surface of the welded portion 412 while being inserted into the through-hole 415 formed in the flange portion 413, so that the door latch device 3 is engaged with the striker 4. When the door 2 is closed, that is, when the door 2 is constrained in a closed state, the door 2 is deformed forward or obliquely forward by a rear collision of the vehicle, etc. Alternatively, when a force for deforming in the left-right direction is applied, both the leg portions 421 come into contact with the inner edges of both through-holes 415 to prevent the deformation of both leg portions 421 in the front-rear and left-right directions. . Thereby, the force which acts on the welding part of the engagement rod 42 and the base member 41 is relieved inevitably, and the strength improvement of the striker 4 can be aimed at.

  The dimensional relationship between the leg portion 421 and the through hole 415 may be set so that the leg portion 421 contacts the inner edge of the through hole 415 in advance, or when the leg portion 421 is slightly deformed, the through hole 415 You may set so that it may contact | abut to the inner edge.

  As described above, in the striker 4 of the present embodiment, when an excessive force is applied to the engagement rod 42, the both leg portions 421 come into contact with the inner edge of the through hole 415 provided in the flange portion 413, Since the deformation of both leg portions 421 can be prevented, the strength of the striker 4 can be improved. Further, since the through hole 415 provided in the flange portion 413 is not open on one side like the concave support portion of Patent Document 2, both the leg portions 421 are free from deformation of the through hole 415 against deformation in any direction. It can abut against the inner edge. Furthermore, since the base member 41 is not configured to match the main base member and the cover plate as in Patent Document 1, the number of components can be reduced and the configuration can be simplified.
