なる。The engaging rod 13 is manufactured by bending a straight metal round bar (usually about 7 mm in diameter) into a U-shape. In the present invention, the metal round bar shown by a dotted line in FIG. Pressing is performed in advance, and the cross-sectional shape of both the connecting rod 16 and the support leg 15 or at least a portion corresponding to the connecting rod 16 is processed into a substantially crescent shape like a solid line cross section. After forming the concave portion 17, it is bent into a U-shape. As a result, on the inner surface of the connecting rod 16 facing the side surface 20 of the latch 3, two ridges 1 spaced at a predetermined vertical interval are provided.
When the striker 9 is pulled rearward by the force Y in the longitudinal direction of the vehicle body in FIG. 3, the two ridges 18 and 19 collide with the side surface 20 of the latch 3.

バープレート８に押し付ける。When the door is closed, the engagement leg portion 14 of the engagement rod 13 of the striker 9 is engaged with the engagement groove 10 of the latch 3,
When the latch 3 is rotated, the ratchet 6 is engaged with the engagement step 5 of the latch 3 to prevent reverse rotation, and the door is closed (FIG. 1). In this state, when a force Y in the vehicle body front-rear direction is applied to the door due to a collision or the like, the connecting rod 16 of the striker 9 connecting the tips of the engaging leg 14 and the supporting leg 15
The latch 3 is moved rearward while being in contact with the side surface 20, and pressed against the cover plate 8.

容易になる。FIG. 4 shows the relationship between the connecting rod 16, the latch 3 and the cover plate 8 at this time.
Is sandwiched between the cover plate 8 and the connecting rod 16. After this state, when the force Y is further applied to the striker 9, the force Y comes into contact with the cover plate 8 and acts to forcibly press the latch 3 that cannot move backward any more. , Connecting rod 1 of striker 9
6, two ridges 18, 19 are formed on the inner surface side, so that the force Y is dispersed by the two ridges 18, 19 and transmitted to the latch 3, so that the strength of the latch 3 is correspondingly increased. Countermeasures become easy.

なく、実用的である。Since the two ridges 18 and 19 are formed by providing a substantially crescent-shaped concave portion 17 on the inner surface side of the connecting rod 16, a metal round bar having a conventional thickness is pressed. If it is sufficient strength can be obtained and the thickness does not need to be changed, it is practical without affecting other components of the lock device.

向上する。As described above, when the connecting rod G of the striker pulls the latch D rearward by the force Y in the front-rear direction of the vehicle body and strongly presses the latch D against the cover plate I of the lock device C, it can be moved further rearward. Since the latch D is locally pressed by the circular side edge of the connecting rod G, the strength of the latch D becomes unstable. Therefore, as shown in FIG. 9, there is a known example in which the connecting rod G is formed into a flat shape in which both sides are flattened and the contact area with the latch D is increased, but when the connecting rod G is formed into a flat shape as shown in FIG. And the strength of the connecting rod G itself decreases. However, according to the present invention, there is provided a mounting plate 12 made of a metal plate abutted and fixed to a vehicle body 11;
A pair of engaging and supporting legs 14 and 15 consisting of metal rods having substantially the same length and fixed at right angles to the base at predetermined intervals with respect to 2, and a metal rod connecting the tips of the legs 14 and 15 In the striker composed of the connecting rod 16 made of, the connecting rod 16 and the supporting leg 15 have a pair of ridges 18 and 19 at least on the inner surface side of the connecting rod 16 on both upper and lower sides. Since the striker for the vehicle door lock device is formed in a shape, the local strong pressure on the latch 3 can be prevented while the strength of the striker itself is sufficiently maintained. In the above, the support leg 15
Is a striker for a vehicle door lock device in which the inner side cross-sectional shape has a pair of ridges 21 and 22 on both the upper and lower sides, so that the strength against the force X in the door opening and closing direction is also improved.
