One of them is shown in FIG. That is, the rear suspension member 10 is connected to the vehicle body 1.
1, a bolt 13 that passes through the cushion 12 is made long, and a mass member 15 is attached to the part of the bolt that projects downward from the stopper 14, thereby changing the resonance frequency. However, with this structure, in order to change the resonance frequency range and obtain a sufficient effect, it is necessary to increase the weight of the mass member 15 and the overall length of the bolt, but it is necessary to Since there is a limit to increasing the overall length of the bolt due to the height, the weight of the mass member 15 cannot be increased, and sufficient effects cannot be expected.

(Means for Solving the Problems) The present invention has a structure in which a rear suspension member having a bushing of a cylindrical elastic body is attached to a vehicle body member located above the bushing.
a stopper to which a mass member is fixed, which is disposed below the bushing and is coupled to the vehicle body; and a cylindrical member which is disposed through the bushing and abuts against the vehicle body member and the stopper at its upper and lower ends. The stopper is coupled to the bolt so as not to be relatively movable by a bolt passing through the vehicle body member, the cylindrical member, and the stopper, and a nut screwed into the bolt.

(Operations and Effects) Since the mass member is fixed to the stopper and the stopper is coupled to the bolt so that relative movement is not possible, the mass member increases the mass of the bolt and functions as a mass damper. As a result, the resonant frequency range of the bolt changes, and resonance of the bolt is prevented, and the generation of abnormal noise due to resonance can be suppressed.

Since the mass member is fixed to the stopper rather than the bolt by welding or other means, there is no need to increase the overall length of the bolt, and the mass member can be made into a flat plate shape, and the size of the stopper and therefore this Since the plane size and shape of the mass member fixed to the stopper can be arbitrarily determined regardless of the plane size and shape of the cushion, the weight of the mass member can be controlled without limiting the ground height of the rear suspension member. can be determined without receiving,
It becomes easy to select an accurate weight.
