Patent ID: 7594559

Claim:
A connecting structure comprising: a sub-frame extending horizontally in a front to rear direction of a vehicle having the connecting structure; a vehicle body frame connected to the sub-frame and extending horizontally in the front to rear direction of the vehicle, the sub-frame and the vehicle body frame being vertically spaced apart; a connecting member having an upper end and a lower end with a longitudinal axis extending therebetween; and an insulator attaching the upper end of the connecting member to the vehicle body frame, the insulator including an outer tube disposed on the longitudinal axis and fixed to the upper end of the connecting member, an inner tube disposed on the longitudinal axis of the connecting member and fixed to the vehicle body frame by a bolt extending through the inner tube, and an elastic body elastically coupling the inner and outer tubes so as to allow for mutual rockability between the vehicle body frame and the connecting member, such that a restraining force in a rotational direction is smaller at the upper end than at the lower end, the inner tube, the outer tube and the elastic body extending along the longitudinal axis of the connecting member, the sub-frame being connected to the connecting member at a location disposed completely below a bottom end of the insulator.
