Abstract:
1. A muffler hanger composed of a rubber elastic body, adapted to elastically hang a muffler from a floor of a vehicle body of an automotive vehicle and to absorb vibration between the muffler and the vehicle body, the muffler hanger comprising: (a) a rubber annular portion of continuous ring shape in the circumferential direction; (b) a rubber arm integrally formed with the rubber annular portion so as to interconnect vertically-medial regions of the rubber annular portion in a vehicle left-right direction, and constituting an elastic support portion for the muffler which extends in the left-right direction; (c) an upper space and a lower space formed between the rubber arm and the rubber annular portion for permitting deformation of the rubber arm; (d) a first mounting hole disposed in a center of the rubber arm in the vehicle left-right direction so as to extend in a vehicle front-back direction when installed on the vehicle, and adapted to be attached in a mated condition to a support pin provided on one of a muffler side and a vehicle body side; and (e) a pair of second mounting holes disposed at locations away to right and left sides from the first mounting hole so as to extend in the vehicle front-back direction when installed on the vehicle, and adapted to be attached in a mated condition to support pins provided on an other of the muffler side and the vehicle body side, wherein the first mounting hole and the second mounting holes are arranged to form a row in the vehicle left-right direction, with positional relationships such that when installed on the vehicle the holes overlaps one another as viewed in the vehicle left-right direction, wherein the rubber arm is disposed between opposing faces of the first mounting hole and the second mounting holes in the vehicle left-right direction, and wherein sections of the rubber annular portion that face the rubber arm from above and below constitute outer stopper portions for limiting displacement of the rubber arm in a vertical direction.
