<P>PROBLEM TO BE SOLVED: To provide a packing structure which prevents the generation of a discarded material or the like as much as possible during molding operation while improving a packing property. <P>SOLUTION: A packing member 10 where a string-shaped body 11 arranged to surround a square packing mounting part 1A along it is formed in a shape of a square frame is constituted by mutually joining divided ends, formed by dividing the string-shaped body 11 at four corners 11-1 thereof as junction surfaces 11a-11d. Wraparound junction pieces 11a-1 and 11b-1 which wrap around the other junction surfaces 11c and 11d and are joined while being superimposed thereon are formed in one junction surfaces 11a and 11b out of a pair of junction surfaces, and the packing structure between both the junction surfaces 11a-11d is constituted by joining the wraparound junction pieces 11a-1 and 11b-1 to the other junction surfaces 11c and 11d. <P>COPYRIGHT: (C)2011,JPO&INPIT |
