PROBLEM TO BE SOLVED: To reduce an extra space of a small pump to reduce the vertical overall length as much as possible. SOLUTION: In this small pump 1, a pump case 2 for storing a pump part P of the small pump 1 comprises an upper pump case 3 forming a top plate and a lower pump case 4 integrally connected to the upper pump case 3. The lower part of the lower pump case 4 is integrally fitted to a motor case 5 side wall for storing a motor part M, and the pump part P is provided in the upper side of one space part A formed by the pump case 3 and a motor case 5. The motor part M is provided below the space part A, and a lower end part of an eccentric rotating shaft 30 is loosely fitted to a rotor 6a of a motor 6. COPYRIGHT: (C)2008,JPO&INPIT
