Next, the operation of this embodiment will be described.

In the anchor device 10 having the above configuration, when the assembly pin 12 is assembled to the plate 16, the cover 24 and the spring 36 are attached to the plate body 18 and the webbing to the plate body 18 and the cover 24. The longitudinal tips of 44 are connected.

Then, the large diameter portion 12C of the assembly pin 12 is inserted into the insertion hole 34 of the cover 24 (covering frame 30) from the rear side, and the large diameter portion 12C is inserted behind the limiting portion 42A of the spring 36 (restriction piece 42). (See (A) and (B) of FIG. 3).

Further, the plate 16 is moved (sliding) upward, and the small diameter portion 12B of the assembly pin 12 moves to the locking hole 22 of the plate body 18 via the pair of regulating protrusions 32 of the cover 24 (covering frame 30). By doing so, the rear surface of the large diameter portion 12C is guided by the inclined surface 32A of the cover 24 (regulatory protrusion 32), and the plate 16 is moved to the rear side while being moved upward ((A) in FIG. 4 and). (B)). Therefore, the main body portion 36C of the spring 36 is elastically tilted to the front side by the large diameter portion 12C (the limiting piece 42 of the spring 36 may be elastically tilted to the front side), and the limiting portion 42A of the limiting piece 42 is elastically tilted to the front side (one). Moved to the side). Moreover, the large diameter portion 12C is inserted between the upper end portion of the urging piece 40 and the plate body 18, and the upper portion of the urging piece 40 is elastically tilted forward.

After that, the plate 16 is further moved upward, and the small diameter portion 12B of the assembly pin 12 is fitted to the lower side surface of the locking hole 22 of the plate body 18 ((A) and (B) of FIGS. 5). (See), the assembly pin 12 is arranged at the penetrating position to the plate body 18 (the small diameter portion 12B is penetrated through the plate body 18), and the assembly pin 12 is arranged at the locking position to the plate body 18. (The movement of the plate body 18 to the front side is locked by the large diameter portion 12C of the assembly pin 12). Further, when the limiting portion 42A of the spring 36 (restricting piece 42) passes through the large diameter portion 12C upward, the main body portion 36C of the spring 36 is elastically tilted (elastically restored) to the rear side, and the limiting portion 42A is rearward. Moved to the side (other side). Therefore, by arranging the limiting portion 42A above the large diameter portion 12C, the downward movement of the limiting portion 42A is restricted by the large diameter portion 12C, and the assembly pin 12 is assembled to the plate 16. (Retained).

Here, when the assembling pin 12 is moved to the lower side (locking position side) with respect to the plate 16, the inclined surface 32A of the cover 24 (regulatory protrusion 32) causes the assembling pin 12 to be on the front side (locking position side) with respect to the plate 16. Move to the penetration position side). Therefore, the assembly pin 12 can be moved to the front side with respect to the plate 16 by moving the assembly pin 12 downward with respect to the plate 16, and the small diameter portion 12B of the assembly pin 12 easily penetrates the plate body 18. The assembly pin 12 can be easily assembled to the plate 16.

Further, the inclined surface 32A moves the assembling pin 12 to the front side with respect to the plate 16, and the large diameter portion 12C of the assembling pin 12 moves the limiting portion 42A of the spring 36 (restriction piece 42) to the front side. Therefore, the limiting portion 42A can be easily moved to the front side.

Moreover, when the large diameter portion 12C of the assembly pin 12 is inserted into the insertion hole 34 of the cover 24 (covered frame 30) from the rear side, it is inserted by the regulating surface 30B of the covering frame 30 and the pair of regulating protrusions 32. The insertion position of the large diameter portion 12C into the hole 34 is restricted in the vertical direction. Therefore, the large diameter portion 12C can be appropriately arranged behind the limiting portion 42A by inserting it into the insertion hole 34, and the inclined surface 32A moves the assembly pin 12 to the front side with respect to the plate 16 so that the large diameter portion 12C can be appropriately arranged. 12C can appropriately move the limiting portion 42A to the front side.

As a result, in the present embodiment (see the solid line X in FIG. 6), when the assembling pin 12 is moved downward with respect to the plate 16, the moving load of the assembling pin 12 with respect to the plate 16 increases and the maximum value (see). After reaching F1 in FIG. 6), the assembling pin 12 (large diameter portion 12C) passes through the limiting portion 42A (see P1 in FIG. 6), and the moving load of the assembling pin 12 with respect to the plate 16 decreases. This completes the assembly of the assembly pin 12 with respect to the plate 16.

On the other hand, for example, in the case of the comparative example in which the assembly pin 12 is inserted above the limiting portion 42A (see the broken line Y in FIG. 6) as in Patent Document 1, the limiting portion 42A is below the large diameter portion 12C. When riding from the side to the front side of the large diameter portion 12C (see Q in FIG. 6), the moving load of the assembly pin 12 with respect to the plate 16 becomes the maximum value (see F2 in FIG. 6), and is below the large diameter portion 12C. The riding of the limiting portion 42A from the side to the front side is completed, and the moving load of the assembly pin 12 with respect to the plate 16 is reduced. Then, the assembling pin 12 (large diameter portion 12C) passes through the limiting portion 42A (see P2 in FIG. 6), and the moving load of the assembling pin 12 with respect to the plate 16 decreases, so that the assembling pin with respect to the plate 16 is lowered. The assembly of 12 is completed.

Therefore, in the case of the comparative example, the movement stroke of the assembly pin 12 from the insertion position to the locking position with respect to the plate 16 becomes large (see S2 in FIG. 6). On the other hand, in the present embodiment, the movement stroke of the assembly pin 12 from the insertion position to the locking position with respect to the plate 16 can be reduced (see S1 in FIG. 6), and the assembly pin 12 can be easily assembled to the plate 16. it can.

Further, in the case of the comparative example, the maximum value of the moving load of the assembly pin 12 with respect to the plate 16 is when the limiting portion 42A rides on the large diameter portion 12C from the lower side to the front side of the large diameter portion 12C (FIG. 6). The moving load becomes larger (see F2 in FIG. 6). On the other hand, in the present embodiment, since the limiting portion 42A does not ride on the front side of the large diameter portion 12C from the lower side of the large diameter portion 12C, the maximum value of the moving load of the assembly pin 12 with respect to the plate 16 can be reduced (FIG. 6). The assembly pin 12 can be more easily assembled to the plate 16 (see F1).

Moreover, in the case of the comparative example, the loading of the limiting portion 42A from the lower side to the front side of the large diameter portion 12C is completed (see Q in FIG. 6), and the moving load of the assembly pin 12 with respect to the plate 16 decreases. After that, the assembling pin 12 (large diameter portion 12C) passes through the limiting portion 42A (see P2 in FIG. 6), and the moving load of the assembling pin 12 with respect to the plate 16 decreases, so that the assembling pin 12 is assembled with respect to the plate 16. The assembly of the pin 12 is completed. On the other hand, in the present embodiment, the limiting portion 42A passes through the assembling pin 12 (large diameter portion 12C) (see P1 in FIG. 6) and is assembled before the moving load of the assembling pin 12 with respect to the plate 16 is lowered. Since the moving load of the attachment pin 12 with respect to the plate 16 does not decrease, it is possible to suppress the end of the movement of the assembling pin 12 with respect to the plate 16 before the assembling of the assembling pin 12 with respect to the plate 16 is completed.

Further, the cover 24 is provided with an inclined surface 32A. Therefore, in order to provide the inclined surface 32A on the spring 36, for example, the spring 36 has a U-shaped cross section as in the second embodiment of the above-mentioned Patent Document 1, and the limiting portion 42A is provided on the front side portion of the spring 36 and the spring.
