ABSTRACT:
A power blower has a fan housing, a blowing fan accommodated in the fan housing, a drive source for driving the blowing fan, an operating handle connected to the fan housing for gripping by an operator of the power blower, and at least one vibration damping member interposed between the operating handle and the fan housing. The vibration damping member has resiliently deformed protruding portions contacting an inner peripheral surface of the operating handle so that vibrations in three directions, passing from the drive source and blowing fan to the fan housing, are absorbed by resilient deformation of the protruding portions to thereby suppress vibrations passing via the fan housing to the operating handle.
