To attain the cost saving, the integration of an impeller and a motor yoke of an outer rotor type motor drive blower can be performed in a one-touch manner in a working process for fixedly attaching the motor yoke within the impeller. The motor yoke 6a is formed to have a cylindrical portion. Also, the impeller 5 is integrally formed of elastic synthetic resin with a cylindrical portion 5a within which the motor yoke 6a can be fixedly attached and fans 5b around the cylindrical portion with hooking members (bosses) 12 for the motor yoke 6a. Then, the motor yoke 6a and the impeller 5 are integrally formed with each other by engaging the elastic hooking members 12 with the motor yoke 6a when the motor yoke 6a is fixedly attached within the cylindrical portion 5a of the impeller 5.
