PROBLEM TO BE SOLVED: To provided an artificial heart pump capable of easily determining the arranging positions of permanent magnets so as to set the gaps between a rotor and fixed bodies to optimum distances. SOLUTION: Magnetic repulsive forces by respective permanent magnets 3a, 5b, 5c, 8a are adjusted to set the gaps between both end faces of a sleeve 5 and the end faces of respective fixed bodies 3, 8 to optimum distances. The fixed bodies 3, 8 are consisted of parts 31, 81 for fixed body and cones 32, 82 which are to be inserted into the parts 31, 81 for fixed body and of which the tip part protrudes.
