Abstract

A vibration-damping device (10) has a first body (11) connected to a vibration receiving section, a second body (12) placed on the opposite side of the first body (11) from a vibration generating section, a connector (13) penetrating through the first body (11) and interconnecting the second body (12) and the vibration generating section, body rubber (14) for elastically interconnecting the firstbody (11) and the second body (12) and having an inner space (K) through which the connector (13) penetrates, a tubular stopper fitting (15) provided to the first body (11) and radially externally surrounding a rod-like contact section (16) fitted to the connector (13), and tubular stopper rubber (17) mounted to at least either the inner surface of the stopper fitting (15) or the contact section (16). The distance between the opposed surfaces of the inner surface of the stopper fitting (15) or the contact section (16) is uniform in the entire opposed areas. In the vibration-damping device (10), a load applied to the stopper rubber (17) is reduced to improve the durability of the device.

Description

technical field [0001] The present invention relates to vibration isolation devices used, for example, in automobiles, industrial machinery, and the like. This application claims priority to Japanese Patent Application No. 2008-48560 for which it applied to Japan on February 28, 2008, and uses the content here. Background technique [0002] As this kind of vibration isolating device, there is conventionally known such as the device shown in the following patent document 1, and this device comprises: the 1st main body member, and it is connected with the vibration receiving part; The main body member is arranged on the side opposite to the vibration generating part; the connecting member penetrates through the first main body member and is used to connect the second main body member and the vibration generating part; the main body rubber elastically connects the first main body member and the first main body member. 2. A main body member with the connecting member penetratin...
