According to the present invention, the lower cover 2 is fitted to the seat body 1 and the boss 3 is pressed into the stop hole 4 and the lower cover 2 is mounted. By fitting the pins 9 into the holes 7 and 8 and the pins 10 into the holes 11, respectively, the seat cover can be completely mounted. At this time, the seat receiving covers 2 and 5 are both made of plastic and have an appropriate elasticity. The covers 9 and 10 are easily expanded by slightly expanding the covers in the step of fitting the pins 9 and 10. It allows insertion. As described above, according to the present invention, a lower cover 2 having an upward opening having the same shape is fitted to a lower portion of a seat receiving body 1 fixed to a pillar, and a boss 3 projecting from a bottom surface of the lower cover 2 is attached to the seat. A stopper hole 4 formed in the bottom of the receiving main body 1 is press-fitted and fixed, and an upper cover 5 of the same shape is fitted on the upper part of the seat receiving main body 1 to cover the lower cover 2 and the respective opening edges. The pins 9 are inserted into the joining pieces 6 protruding on both sides of the lower cover 2 and the holes 7 and 8 formed on the side faces of the seat body 1 on both sides of the upper cover 5. And upper cover 5
The pin 10 pushed inwardly inside the rear of the seat body is fitted into a stop hole 11 formed in the rear side surface of the seat body 1, and the seat body 1 is completely fixed by the seat covers 2, 5. It is possible to obtain a chair that is very good in appearance without being exposed to the outside, and that the added value of the product is enhanced by applying a suitable makeup to the seat cover, thereby increasing the value of the product.
