PURPOSE:To limit abnormally large displacement by arranging the expanded diameter portion of a stopper so as to engage with the receiving portion of the stopper when a large displacement occurs in the vibration absorbing direction. CONSTITUTION:The central portion of a supporting member 30 is formed in a protruded portion 42 deformed in the thickness direction and an elastic body 46 is stuck to the upper part of the protruded portion 42 by vulcanizing. The circumference of the elastic body is connected to a supporting member 50 through an upper cylinder 48. When the supporting member 50 makes a large relative displacement against the supporting member 30 by the actuation of a powerful acceleration of a vehicle in an emergency state, an expanded diameter portion 58 engages with the protruded portion 42, whereby limiting large displacement of the supporting member 50 against the supporting member 30. |
