PROBLEM TO BE SOLVED: To provide a molding tool for a fluid bearing device housing with an enhanced coaxiality of the inner peripheral surface with the outer peripheral surface of a resin-made housing. SOLUTION: In this molding tool, a cavity side part 21 has an adjustable outer mold part 21c which is adjustably movable in a radial direction and an adjustment mechanism 21d which adjusts a position in the radial direction of the adjustable outer mold part 21c. It is possible to secure the coaxiality of the axial centers of the adjustable outer mold part 21c and a spindle-like inner mold part 22a with high precision by adjustably moving the adjustable outer mold part 21c in the radial direction with the help of the adjustment mechanism 21d and thereby, adjusting the position in the radial direction of the adjustable outer mold part 21c to the spindle-like inner mold part 22a.
