摘要

PROBLEM TO BE SOLVED: To increase a degree of freedom in setting a spring rate of a bush main body while preventing the generation of noise caused by the rattling of the rubber bush main body of a damper mount bush.;SOLUTION: As a plurality of upper projections 31b and lower projections 32b to be compressed by washers are provided on an upper face 31 and a lower face 32 of the rubber bush main body 21 of the damper mount bush 17 elastically supporting an upper end of a damper on an upper wall of a wheel house, the bush main body 21 can be retained between the washers only by compressing the upper projections 31b and the lower projections 32b. Thus the application of initial compression load to the bush main body 21 by the washers becomes unnecessary, the formation of a clearance between the washer and the bush main body 21 can be prevented without limiting the degree of freedom in setting the spring rate of the bush main body 21 by initial compression load, and the generation of noise caused by vibration of the washers and the generation of slapping sound in inputting large load can be prevented.;COPYRIGHT: (C)2006,JPO&NCIPI
