Abstract:
1. A stopper structure of a torque rod mounted straddling an engine side and a body side of a vehicle, receiving torque from the engine, and regulating displacement in a roll direction of the engine, the stopper structure comprising: a first bush provided on a first end of the torque rod, the first bush comprising: a first rigid outer member having a tubular shape, a first rigid inner member disposed inside the first rigid outer member, and a first rubber elastic body sandwiched between the first rigid outer member and the first rigid inner member; a second bush provided on a second end of the torque rod, the second bush comprising: a second rigid outer member having a tubular shape, a second rigid inner member disposed inside the second rigid outer member, and a second rubber elastic body sandwiched between the second rigid outer member and the second rigid inner member; and a rigid connector connecting the first bush and the second bush, wherein at least one of the first bush and the second bush is fastened and fixed to a mating fastening member in a state in which the corresponding one of the first rigid inner member and the second rigid inner member is sandwiched in an axial direction by the mating fastening member; one of the first bush and the second bush is provided with an acceleration-side rubber stopper on an acceleration side projecting from the corresponding one of the first rigid outer member and the second rigid outer member toward the corresponding one of the first rigid inner member and the second rigid inner member; and the corresponding one of the first rigid inner member and the second rigid inner member is provided with an acceleration-side stopper contact on the acceleration side having an acceleration-side two-pronged projecting front end portion, from the axial view, to form an acceleration-side recessed space that receives insertion of the acceleration-side rubber stopper; the acceleration-side rubber stopper has a shape in which a rubber thickness in the axial direction is increased toward the acceleration-side two-pronged projecting front end portion; the mating fastening member extends axially outward of the acceleration-side rubber stopper; and a bulge space for the acceleration-side rubber stopper to bulge axially outward is provided axially inward of the mating fastening member; and the acceleration-side rubber stopper deforms to fill the acceleration-side recessed space after coming in contact with the acceleration-side stopper contact in a stopper function, and further bulges and deforms in the axial direction into the bulge space to come in contact with the mating fastening member.
