VIBRATION ISOLATION APPARATUS FOR BLOWER FAN AND BLOWER FAN STRUCTURE BODY

摘要

PROBLEM TO BE SOLVED: To provide a vibration isolation apparatus for a blower fan solving various problems incidentally created when a blower fan is formed on a conventional vibration isolation apparatus outer tube, and a blower fan structure body provided with the same. SOLUTION: This invention relates to a vibration isolation apparatus for a fan 20 which includes an outer tube 11 for retaining a propeller fan 20 and to which an inner tube 12 is connected via an elastic member 13 at an inside thereof. A step S is formed over a whole circumference of an outer circumference surface of the outer tube 11 and a large diameter side area surface f2 partitioned by the step S is used as a area retaining a hub 21 of the fan 20.
