Abstract:
An ultrasonic welding structure, comprising:a pair of welding members to be welded to each other by oscillating the welding members by ultrasonic waves, the welding members being made of materials soluble by this ultrasonic oscillation;wherein one of the welding members defines at least one recess, the recess having two sidewalls and a bottom, wherein the recess sidewalls are slanted to gradually approach each other as they approach the recess bottom, and wherein the recess sidewalls incline to an amplitude direction of the ultrasonic waves at an angle;wherein the other of the welding members defines at least one projection, the projection having two sidewalls, wherein the projection sidewalls are slanted so as to fit the recess sidewalls when the recess engages with the projection, and wherein the projection sidewalls incline to the amplitude direction of the ultrasonic waves at an angle; andwherein the recess sidewalls and the projection sidewalls may be welded to each other by the ultrasonic oscillation.
