<p>In a vibration welding structure for fixing an attachment to an instrument panel ( 12 ), a first projection ( 70 ) resiliently deformable in a predetermined vibrating direction is provided on the instruction panel ( 12 ) so as to project from the instrument panel ( 12 ) toward an air conditioner duct ( 15 ). A first fitting groove portion ( 72 ) is formed in the air conditioner duct ( 15 ) for fitting engagement with a distal end portion ( 70 a) of the first projection ( 70 ). Further, a first positioning mechanism ( 74 ) is provided between the instrument panel ( 12 ) and the air conditioner duct ( 15 ) for positioning the air conditioner duct 15 in a direction perpendicular to the vibrating direction.</p> |
