2. Description of the Related Art
Conventionally, there has been known a vibration damping device interposed between members constituting a vibration transmission system to link or support the members each other in a vibration damping manner, which has been considered for application to engine mounts and the like on motor vehicles. This vibration damping device, as shown in Japanese Unexamined Patent Publication No. JP-A-11-311291 and others, has a structure where a first mounting member and a cylindrical second mounting member are elastically connected by a main rubber elastic body.
By the way, in the vibration damping device described in JP-A-11-311291, the first mounting member is arranged on the upper side of the second mounting member to be attached to the vibration source such as a power unit, while the second mounting member is attached to the member to be vibration-damped such as a vehicular body. In contrast, Japanese Patent No. JP-B-4755147 proposes an inverted vibration damping device, wherein the first mounting member is arranged on the lower side of the second mounting member to be attached to the member to be vibration-damped, while the second mounting member is attached to the vibration source.
However, since a massive bracket is fixed by press-fitting to the second mounting member constituting the upper portion of the vibration damping device in the vibration damping device shown in JP-B-4755147, the center of gravity thereof is positioned in the upper portion, which posed a risk of developing problems such as lack of rigidity of the vibration damping device in the falling direction.
In addition, in the structure of JP-B-4755147, since an axis-perpendicular stopper member that restricts relative displacement between the first mounting member and the second mounting member in the axis-perpendicular direction (front-back direction of the vehicle) is provided on the upper portion of the vibration damping device, there were some problems such as further deviation upward of the center of gravity position and a risk of adverse effects on the load bearing performance or ride comfort caused by a stopper load of the axis-perpendicular stopper member acting on the upper portion of the vibration damping device during acceleration and deceleration of the motor vehicle. The present invention relates to fastening devices and relates more particularly to a fastening device for fastening a key chain to one'waist belt or clothes.

 Conventionally, there has been know a vibration damping device interposed between member constituting a vibration infection organization to link or back the members each other in a oscillation damping manner, which has been considered for lotion to engine mounts and the like on motor vehicles. This vibration damping device, as shown in Japanese Unexamined Patent Publication No. JP - A-11 - 311291 and others, has a social organization where a first mounting member and a cylindrical second wax member are elastically connected by a chief rubber elastic torso. 
 By the way, in the vibration damping device described in JP - A-11 - 311291, the first mount member is arranged on the upper side of the second mounting member to be attached to the vibration source such as a power unit, while the second mounting member is attached to the member to be vibration - damped such as a vehicular body. In line, Japanese Patent No. JP - B-4755147 propose an inverted oscillation dampen device, wherein the first mounting member is arrange on the lower side of the second mounting member to be impound to the member to be vibration - damped, while the second mounting penis is attached to the vibration source. 
 However, since a massive bracket is fixed by wardrobe - fitting to the second hop on member constituting the upper portion of the vibration damping device in the shaking damping device shown in JP - B-4755147, the center of graveness thereof is put in the upper portion, which posed a hazard of developing problems such as lack of rigidity of the vibration damping device in the hang direction. 
 In accession, in the structure of JP - B-4755147, since an axis - vertical stopper member that restrict relative displacement between the beginning mounting penis and the second mounting member in the axis - perpendicular direction (front - back direction of the vehicle) is provided on the upper portion of the shaking damping device, there were some problem such as further deviation upward of the center of gravity position and a risk of adverse effect on the load bearing performance or ride comfort caused by a stopper lode of the axis - vertical plug member acting on the upper portion of the vibration muffle device during acceleration and deceleration of the motor vehicle. The present invention relates to fastening device and relates more particularly to a fastening device for fastening a key range to one'waist belt or clothes.
