れる。According to the above configuration of the present invention, when assembling the pump, as shown in FIG. The protruding corner portion 16 abuts against the slope portion 14, and the protrusion portion 17 abuts against the slope portion 15, respectively. Therefore, the housing 1 is supported by the pedestal 20,
When the lid 10 is pushed down by the ultrasonic vibration transmitter 21, the abutting portion is heated by the ultrasonic vibrations acting on it, and the lid 10 and the housing 1 are welded together as shown in FIG. Ru.

15 and the protruding corner portions 16° and 17 of the groove portion 12 collide,
By transmitting ultrasonic vibrations of about 14 Z to the lid 10, the vibration energy is concentrated on the abutting portion, resulting in efficient bath contact. The press-fitted elastic path sealing body 19 pushes the cover l due to its repulsive force.
Since the O is positioned in the horizontal direction, the front part should be evenly distributed around the opening so that the protruding part collides with the slope part, increasing the reliability of welding, and ensuring that the casing has sufficient rigidity. It will be done.
