PROBLEM TO BE SOLVED: To provide a canned pump, in which a cylindrical part is formed in one shot of a synthetic resin. SOLUTION: In the canned pump, a magnet provided in the position close to a board 61, and a hollow yoke 22 is provided in the inside of the magnet. The magnet and the yoke 22 are held by melt solidification at the time of molding of a long cylinder 23 made of a synthetic resin. A rotor 7 is also held in the pump, in which hollow cylindrical bearings 24 are held in the inside of the cylinder 23. Thus, the yoke 22 is held from the longitudinal direction at the time of molding the cylinder 23. COPYRIGHT: (C)2003,JPO
