Vibration-preventive support device

A vibration-preventive support device, comprising:

• an outer cylindrical body having a longitudinal axis along a gravitational direction, said outer cylindrical body to be mounted onto a first member of two members to be connected together, said outer cylindrical body being formed of elastic material;
• an inner cylindrical body to be mounted onto a second member of said two members movable with respect to said first member, said inner cylindrical body being formed of elastic material;
• said outer cylindrical body having a first side end edge and a second side end edge and said inner cylindrical body having a first side end edge and a second side end edge;
• and
• a vibration absorbing body formed of elastic material having two ends that are respectively connected to said first side end edge of said outer cylindrical body and to said second side end edge of said inner cylindrical body wherein, in a first condition, said inner cylindrical body is entirely outside a volume encompassed by said outer cylindrical body and wherein, in a second condition, said inner cylindrical body is disposed within said encompassed volume of said outer cylindrical body and, in said second condition, said first side end edge and said second side end edge of said outer cylindrical body are positioned proximal to respective said first side end edge and said second side end edge of said inner cylindrical body, and wherein said absorbing body expands a predetermined length due to weight of said second member and supports the second member through said outer cylindrical body in said second condition.
