PROBLEM TO BE SOLVED: To provide an artificial heart pump which may easily determine setting positions of permanent magnets so as to optimize a gap distance between a rotor and a fixer. SOLUTION: Magnetic repulsive force respectively by permanent magnets 3a, 5b, 5c, 8a is adjusted so as to optimize respective gaps between both end faces of a sleeve 5 and respective end faces of fixers 3, 8. The fixers 3, 8 include fixer parts 301, 801 with opening parts, cone stationary parts 302, 802 to be inserted into the opening parts of the fixer parts 301, 801, cone tip end parts 303, 803 to be inserted into holes set in the cone stationary parts 302, 802, and adjusting rods 12. 12 connected with the permanent magnets 3a, 8a.
