<P>PROBLEM TO BE SOLVED: To provide a toilet seat device which is improved in design without dispersion of sealing performance and strength. <P>SOLUTION: This toilet seat device comprises an upper case 1, a bottom plate 3, and a heater. Either one of the upper case 1 and the bottom plate 3 is structured by a light energy transmissible material and the other by light energy absorptive material. The upper case 1 and the bottom plate 3 are welded together by supplying light energy to the light energy absorptive material via the light energy transmissible material to heat both thereof. A through-hole 13 to transmit light energy is formed on the end part of a surface material 11 set on the upper surface of the upper case 1. hereby, the surface material 11 can be fixed simultaneously with the welding of the upper case 1 and the bottom plate 3 together. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
