Next, as shown in FIG. 1B, the seat cover 5 is put on the seat pad 17. The bent portion of the gusset 10, the gusset 10 and the base end 14A of the seam 14 of the bead 12 are parallel to each other, and the tip bent portion 14B of the seam 14 of the bead 12 and the cover body 6 The bent portion and the cover body 6 are parallel to each other. Therefore, the angle formed by the connecting portion between the “bent portion of the gusset portion 10 and the gusset portion 10” and the “bent end portion 14B of the bead 12, the bent portion of the cover body 6, and the cover body 6” is substantially a right angle. .
This connecting portion approximates the shape of the corner portion 18 of the seat pad 17, and the seat cover 5 is attached to the seat pad 17.
The connector fits snugly into the corners 18. Since it fits in this manner, the work of putting the seat cover 5 on the seat pad 17 is easy, and the appearance is good without the bead body 13 meandering.

After the seat cover 5 is put on, the direction of the bead body 13 is determined because the tip bent portion 14B of the bead 12 is sandwiched between the cover body 6 and the corner of the seat pad 17. Even if the occupant re-seats or shifts his / her waist, and the cover body 6 moves outward (toward the gusset 10), the angle formed by the connecting portion between the cover body 6 and the gusset 10 is maintained at substantially a right angle. When the occupant removes the external force (the orientation of the bead body 13 does not change), the seat cover 5 gradually returns to the state shown in FIG. Further, even if the gusset 10 moves in the direction of the cover body 6, it only moves to the left from the state of FIG.
When the external force is removed by the occupant, the seat cover 5 gradually returns to the state shown in FIG.
