ABSTRACT:
A vibration isolating mount has a columnar vibration isolating rubber body, an upper retaining plate bonded to an upper end surface of the columnar rubber body, a lower retaining plate bonded to a lower end surface of the columnar rubber body, an upper bracket plate made of nonferrous metal and secured to an upper surface of the upper retaining plate, and a lower bracket plate made of nonferrous metal and secured to a lower surface of the lower retaining plate, and two chemical conversion coating layers formed in a lower surface of the upper retaining plate and an upper surface of the lower retaining plate. Each chemical conversion coating layer is made of one of zinc phosphate and calcium zinc phosphate, and improves the adhesive strength between each retaining plate and the rubber body while preventing each retaining plate from peeling off from the rubber body.
