Abstract:
There is a risk that coils of a motor provided in a CPAP device generate heat, thereby reducing the performance of the motor. A CPAP device according to the present invention includes a blower. The blower includes a motor (80) and a blower fan rotated by the motor. The motor includes: a stator assy (85) that has a plurality of coils (87) arranged in the circumferential direction; and a rotor assy (88) that has a permanent magnet (90) and that is disposed on a radially inner side of the stator assy. An output shaft (81) is inserted into the rotor assy. The output shaft rotates together with the rotor assy. The blower fan is fixed at one end of the output shaft. A section of the output shaft is inserted into an insertion hole (84A) provided at the center of a base (82). A slide bearing (91) is interposed between an inner circumferential surface of the insertion hole and an outer circumferential surface of the output shaft.
