The disclosure provides a fixing device for connecting an exhaust system component to a vehicle body, including: a carrier for attachment to the vehicle body; and an elastomer element connected to the carrier. The elastomer element has a connection recess into which a widened end portion of a holding element of the exhaust system component can be inserted, such that a connection region of the elastomer element defining the connection recess at least partially undercuts the widened end portion of the holding element in a joining direction. A fixing device comprises a stiffening structure stiffening the connection region of the elastomer element to impede an extraction of the widened end portion of the holding element.

The vibration isolation device (10) includes a first mounting member (11) connected to one of a vibration generating portion and a vibration receiving portion, and a second mounting member (12) connected to the other thereof; and an elastic body (13) disposed between the mounting members. On either one of opposing surfaces (24, 25) that oppose each other, respectively on the first mounting member (11) and the second mounting member (12), a stopper elastic body (27) having a stopper surface (26) which faces the other of the opposing surfaces (24, 25) such as to be capable of coming into contact therewith, and a hollow portion (30) in which the stopper elastic body (27) is disposed, are provided. The stopper elastic body (27) is fitted into the hollow portion (30) such that, among the surfaces of the stopper elastic body (27), a counter-stopper surface (34) which faces the direction opposed to the stopper surface (26), is in a state of non-contact.
