PROBLEM TO BE SOLVED: To eliminate the need for a filament member corresponding to the specifications of a pad material and to eliminate the need for the separation and differentiation of each material at the time of disposal by engaging and covering a pad with a surface material by the insertion of a pin. SOLUTION: In a seat, a pad is engaged and covered with a surface material 103 by the insertion of a pin 5, and it is preferable that the pin 5 has a section resistant to a drawing force from the pad material 1. A pin with a dish provided with a dish 51 at the upper part is suitably used for the pin 5, and it is possible to engage the pad material 1 with the surface material 103 easily simply by pressing the dish 51. The shaft part 52 of the pin 5 to be embedded in the pad material 1 is provided with a helical structure for providing a binding force for the pin 5 and the pad material 1, and the tip part 53 of the pin 5 is tapered so as to be easily inserted into the pad material 1. As the pin 5 is passed through the surface material 103 and the pad material 1, it is possible to engage the surface material 103 with the pad material 1 easily. As the pin 5 can be inserted simply by specifying a location of insertion on the surface material 103 in the design of a seat, it is possible to reduce the number of man-hours in engagement work greatly.
