Further, the cover body 8 has a stepped portion 8f which is formed one step lower at the center front portion including the holes 8d, 8d of the base portion 8a (see FIGS. 9 and 10).

The cover cap 9 has a pair of protrusions 5, 5 projecting from the upper and lower ends of the base portion 9a, and a bag-like portion 9b that opens to one side and rearward at the center thereof. The base portion 9a is formed to correspond to the shape of the stepped portion 8f of the cover body 8. The cover cap 9 is formed by integrally forming a base portion 9a, a bag-shaped portion 9b, and protrusions 5,5.

The state where the cover body 8 and the cover cap 9 are assembled to each other is shown in FIGS. 3 to 6.

In this assembled state, the protrusions 5 and 5 are formed in the holes 8 of the cover body 8.
It is inserted through d and 8d. When inserted in this way, the protrusion
Since the elasticity of 5 and 5 engages with the holes 8d, 8d, it is difficult for them to come off from the holes. In order to prevent the protrusions 5 and 5 from coming off more reliably, the protrusions 5 and 5 may be provided with retaining claws 5a and 5a (see FIG. 5).

The passive anchor hole cover 6 is a hole in the cover body 8.
It is fixed to the center pillar 4 by bolts (not shown) inserted through 8e, 8e. In this state, the base portions 8a and 9a of the passive anchor hole cover 6 are brought into contact with the outer surface of the center pillar 4, and the upright pieces 8c and the bag-shaped portion 9b are positioned inside the center pillar through the hole 4a. (See Figure 3).

Further, in the above state, the projections 5, 5 of the passive anchor hole cover 6 are located slightly forward of the hole 4a of the center pillar 4 and on the outer side surface.

Next, the operation of this embodiment will be described.

Now, when the door 2 is closed, the inner surface of the door sash 2a projects.
Abut on 5,5. Therefore, the anchor plates 3 are prevented from directly contacting the center pillars 4 and damaging each other.

Further, in this embodiment, the passive anchor hole cover 6 is used.
Since the upright portion 8c is positioned rearward and the bag-shaped portion 9b is positioned forward in a state in which is mounted on the center pillar 4, for example, when a load is applied to the seat belt 7, The load causes the anchor plate 3 to be a door sash.
2a is moved forward, and accordingly, the engaging portion 3b having a T-shaped cross section formed at the tip of the one end 3a of the anchor plate 3 is moved forward, thereby engaging the hole 4a. Can be configured to. This is because the forward movement of the engaging portion 3b is not restricted by the bag-shaped portion 9b.

Although the projections 5, 5 are provided on the outer side surface of the center pillar 4 in the above-described embodiment, the present invention is not limited to this and may be provided on the inner side surface of the door sash.

e. Effect of the Invention As described above, according to the seat belt support structure of the present invention, the anchor plate 3 supporting the seat belt is fixed to the door sash 2a, and one end of the anchor plate 3 is closed when the door is closed. Hole where the part 3a is provided in the center pillar 4
The seat belt support structure to be inserted into 4a includes a passive anchor hole cover 6 configured by a cover body 8 and a cover cap 9. The cover body 8 is formed of a hard resin or the like, and has an opening 8b at the center of its base. Has a standing piece 8c on the vehicle rear side of the opening, and has a pair of holes 8d at the upper and lower ends of the base, and the cover cap 9 is made of an elastic material such as soft resin. The base 5 is provided with a pair of protrusions 5 at the upper and lower ends thereof, and a bag-shaped portion 9b is formed at the center thereof, and the protrusions 5 of the cover cap are inserted and engaged with the pair of holes 8d of the cover body. At the same time, by matching the bag-shaped portion 9b of the cover cap 9 with the opening of the cover body 8, the cover cap 9 is assembled to the cover body 8 to form the passive anchor hole cover 6. When fixing the passive anchor hole cover 6 to the center pillar 4, the upright piece 8c of the cover body and the bag-shaped portion 9b of the cover cap are fitted into the hole 4a of the center pillar 4, and the cover body 8 and the cover cap 9 are inserted. Since the base portion is brought into contact with the outer surface of the center pillar 4 and the projection of the cover cap 9 is located on the outer surface of the center pillar 4, the following effects can be obtained.

That is, according to the present invention, when the door is closed, the door sash is prevented from abutting on the center pillar of the anchor plate by the base of the cover body and the cover cap, and the door sash is elastically protruded by the cover cap. The sash is prevented from coming into contact with the center pillar, and the bag-shaped portion of the cover cap prevents the anchor plate from coming into contact with the center pillar at the time of engagement. Accordingly, it is possible to reliably prevent the anchor plate and the center pillar from coming into contact with each other and damaging each other.

Moreover, in the present invention, since the hole of the center pillar is covered by the passive anchor hole cover,
The inside of the center pillar cannot be seen from the outside, and the appearance is improved.

Further, in the present invention, since the cover body that requires strength is made of a hard resin, and the cover cap that is required to be relatively flexible is made of an elastic material such as a soft resin, The forward movement of the anchor plate is not restricted by the bag-shaped portion of the cover cap, so that the function of the anchor plate can be sufficiently exerted.
