The metal wire 22 is passed through each recess 21
Is buried. On the other hand, on the upper surface of the shell 23, a bifurcated engagement portion 24 that can be inserted into each recess 21 is press-fitted into the boss hole or fixed with a tapping screw or the like. Then, while inserting the engaging portion 24 into the concave portion 21, the back surface of the cushion 20 and the upper surface of the shell 23 are overlapped and strongly pressed against each other, so that the wire 22 exposed in each concave portion is attached to each engaging portion 24. Press fit fit.

係合部を備えたもの（図６参照）がある。In this engagement type, instead of disposing the same engagement fitting around the shell, a plurality of engagement portions having different shapes are integrally provided on the shell (Japanese Patent Laid-Open No. 4-246309). Japanese Patent Application Laid-Open Publication No. H11-157, or an apparatus provided with an engaging portion formed integrally with the shell only in part to reduce fastening points by screws (see FIG. 6).

5, a bifurcated engagement portion 26 for holding a wire in a notch groove 26a of an upright wall protruding at both left and right positions of the shell, and a notch groove at two parallel upright walls protruding at a rear position of the shell. It is provided with another forked engaging portion 27 provided.

保持リブ３０の強度を高めている。In the latter structure, a bifurcated engagement portion 24 (not shown) is attached to each of the six boss holes 28 in FIG. A rib 30 is provided. Then, as shown in the enlarged view of FIG. 7, these pairs of holding ribs 30 face each other without being engaged with each other, one of the ribs 29 has an arc-shaped receiving surface 31 serving as a seat for a wire, and the other has a circular-shaped receiving surface 31. The rib 29 'has a wedge-shaped pressing portion 32 at the upper end, and a partition rib 33 for reinforcing the rearward recoil of the rib is formed on the back surface of each rib,
The strength of the holding rib 30 is increased.

Since the retaining rib 30 is formed integrally with the shell 23, the retaining rib 30 depends on the mechanical properties of the molding material of the shell itself. Warpage is increased, and the holding rib 30 is divided into two columnar rib members, each of which has elasticity. Therefore, there are many problems in terms of strength, and there is a possibility that the holding rib 30 may be biasedly inserted into one of the rib members. strong. For this reason, when the cushion is repeatedly disengaged from the shell, a crack may be formed in the connection portion with the shell, the engagement force may be weakened, and the seat may be easily detached.

る。Further, since the engaging force is weak only by the notch groove of the forked engaging portion, even in the case where the hook-shaped engaging portion 25 provided on the front side of the shell makes up for this, the front portion of the seat sinks or the rear end. There is a drawback that the part side is lifted.

ッション取付け構造を提供することを目的としている。SUMMARY OF THE INVENTION In view of such circumstances, the present invention solves the problem of insufficient strength and unbalance at the time of inserting a wire in a holding rib integrally formed with a shell, and attaching a wire separately from the shell. It is an object of the present invention to provide a structure for mounting a cushion on a chair, which also enables use of a tool.

A boss portion for fixing the tool, and holding ribs formed integrally with the shell near the boss portion and into which the wire is press-fitted. The holding ribs form pairs on both sides of the shell. And a vertical wall forming a contact surface of the wire, and a partition portion extending from at least one side of the vertical wall to the front side and having a concave portion into which the wire is fitted,
And a hooking projection formed on an upper portion of the vertical wall for holding the wire rod.

らクラックが発生することが少なくなる。According to the above construction, the holding rib formed integrally with the shell is formed by joining the partition having the recess and the vertical wall to each other.
It becomes a U-shape or a U-shape, and the strength of the rib is increased. In addition, the pressing force of the wire inserted into the concave portion is also distributed to one end of the concave portion away from the vertical wall and the upper side of the vertical wall, and the portion receiving this pressing force has a shape that somewhat retains elasticity. Therefore, cracks are less likely to occur from the connecting portion at the boundary between the holding rib and the shell.
【００１２】また、保持リブが一体構造であるため成形

Even if the thickness is not increased, the direction of the pressing force of the wire is determined, the press-fitting is smooth, and the effect of bending stress on the holding rib is small.
