<p><P>PROBLEM TO BE SOLVED: To provide a synthetic resin welding object designed to develop the ideal cross sectional shape of the channel leading to a bore by welding two synthetic resin bodies. <P>SOLUTION: In an intermediate synthetic resin member 70, channel-side ends of riser border lines that form the boundaries 78a-1, 78a-2, 78b-1, 78b-2, 78c-1, 78c-2, 78d-1, 78d-2 of individual tip junction surfaces and individual mount junction surfaces are made either contact points or their vicinities of the ridge 84 contact line on the channel side of the preceding individual mount joint surfaces; which face bore-side internal edges 50a, 50b, 50c, and 50d on the preceding tip contact surfaces 74a, 74b, 74c, and 74d. The individual riser border lines 78a-1, 78a-2, 78b-1, 78b-2, 78c-1, 78c-2, 78d-1, and 78d-2, are made to include the preceding channel-side edges and to be parallel with the vibration standard direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
