    Patent number: 6280566
    Abstract: A vibration welding apparatus for welding synthetic resin parts together by vibrating one of the resin parts while the resin parts are in contact with each other. An upper jig for supporting one of the synthetic resin parts, a lower jig for supporting the other of the snythetic resin parts and a vibrating member to which the upper jig is attached are provided in the apparatus. The jigs are held together by bolts which can withstand the vibrating motions. Head portions of the bolts are inserted into insertion holes of the upper jig, notches of spacers are engaged with the shaft portions of the bolts between an attached portion of the upper jig and the head portions of the bolts, and the bolts are fastened to the vibrating member in the state where the notches are engaged with the shaft portions, so that the attached portion is fastened through the spacers by the head portions of the bolts and the vibrating member to thereby attach the upper jig to the vibrating member.
