PROBLEM TO BE SOLVED: To provide a means for performing simple and quick assembly and for obtaining a favorably sealed state with respect to a sealed assembly system in which a miniature pump, whose main body is supported by a sleeve, is pushed in a container having a small capacity to be engaged therewith and seals the container. SOLUTION: A side wall of a sleeve M or of a container R includes a groove region 1 forming a vent hole, and the groove region 1 terminates in a longitudinal direction by the adjacent flat region 2. A flat wall portion 3 opposed to the container R or to the sleeve M clamps the groove region 1 in a radial direction to relatively slide with respect to the groove region 1, and gradually shortens a distance from the groove region 1 to be brought into contact with the flat region in a sealed state, thereby completing assembly. |
