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. Each layer includes a top set of parallel lines, a bottom set of parallel lines intersecting the top set of parallel lines, and memory elements disposed at intersections between the top set of parallel lines and the bottom set of parallel lines. The inner wall surface of the locking member further includes a threaded portion intermediate an end of the locking member and the ledge.
