<p><P>PROBLEM TO BE SOLVED: To provide a formed welt set with which a linear light-emitting body is not moved with respect to a socket due to working of vibrations or tension. <P>SOLUTION: The formed welt set 28 used in a sheet is composed of a round edge 24 and the socket 26. In the round edge 24, a welt core 24A composed of a linear light conductor is integrally formed with a welt outer-coating member 24B composed of a material that allows transmission of light, and the socket 26 is coupled to an end thereof. The socket engaging part 25 of the round edge 24 is engaged with a first member 26A of the socket 26 and the sheet joint-part engaging recessed part 38B of a first member 26B. Therefore, the welt core 24A of the round edge 24 is not moved with respect to the socket 26 due to vibrations or tension, and problems such as a reduction in the light volume of the welt core 24A or no emission of light from the welt core 24A are prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
