PROBLEM TO BE SOLVED: To provide a gas force feed pump for an artificial respiratory apparatus capable of disassembling a motor casing and rotor simply and certainly conducting the wash, sterilization and disinfection, etc. SOLUTION: The gas force feed pump 1 for an artificial respiratory apparatus is equipped with a pump casing 4 to accommodate a gas force feed pump 8 and a brushless motor 3 in which rotor 12 is inserted in a rotor inserting hole 15 opening at the forefront of the motor casing 11. The gas force feed pump 8 is coupled with the tip of the rotor shaft 16 in such a way as rotating in a single body. A thrust magnetic bearing 41 at the forefront is formed from a first magnetic member 43 installed on the side with motor casing 11 and a second magnetic member 44 installed on the side with the rotor tip. The first magnetic member 43 is location on the inside surface of the opening of the rotor inserting hole 15 in its position on the peripheral side of the second magnetic member 44. |
