Patent ID: 8016088

Claim:
A damping mechanism that generates a damping force in response to a liquid flow formed between a first liquid chamber and second liquid chamber, comprising: a partitioning member separating the first liquid chamber and the second liquid chamber; and a flow passage formed in the partitioning member to connect the first liquid chamber and the second liquid chamber, the flow passage comprising an odd number of through-holes greater than three which penetrate the partitioning member and are connected in series, wherein the through-holes comprise: a first through-hole which penetrates the partitioning member; a second through-hole which penetrates the partitioning member in parallel with the first through-hole; and an intermediate through-hole or an odd number of intermediate through-holes which penetrates the partitioning member in parallel with the first and second through-holes, wherein the damping mechanism further comprises: a first communicating groove formed in a surface of the partitioning member facing the first liquid chamber to connect the first through-hole and the intermediate through-hole or one of the intermediate through-holes; a second communicating groove formed in a surface of the partitioning member facing the second liquid chamber to connect the second through-hole and the intermediate through-hole or one of the intermediate through-holes; a first closing member which blocks the communicating groove from communicating with the first liquid chamber; and a second closing member which blocks the second communicating groove from communicating with the second liquid chamber.
