Plastic cylindrical bracket and vibration damping mount assembly using the same, method for producing a resin-made cylindrical bracket

摘要

PROBLEM TO BE SOLVED: To provide a resin cylindrical bracket having a new structure capable of effectively preventing positional shift and drop off due to upward detachment of the anti-vibration mount while avoiding problems such as increase of operation processes caused by providing a bottom metal fitting for a pneumatic actuator specified to be composed of a metal.;SOLUTION: The bottom metal fitting 114 in a dish-like shape for the pneumatic actuator 140 having an outer diameter smaller than an inner diameter of the cylindrical part 102 in the resin cylindrical bracket 20 is provided and connection parts 118 extending out from a plurality of positions on a circumference of the bottom metal fitting 114 toward an outer circumferential side are buried and fixed at a lower end part of the cylindrical part 102. In the part where the connecting parts 118 are fixed, an inner circumferential surface of the cylindrical part 102 is structured by an upper tapered surface 124 extending from an upper side opening part and gradually tapered toward a lower side opening part. In the part where the connecting parts are not fixed, the inner circumferential surface of the cylindrical part 102 is structured by a lower tapered surface 126 extending from the lower side opening part and gradually contracting toward the upper side opening part.;COPYRIGHT: (C)2009,JPO&INPIT
