Patent ID: 8757336

Claim:
A damping mechanism that generates a damping force in response to movement of a fluid between a first fluid chamber and a second fluid chamber of a fluid pressure shock absorber, comprising: a partition wall member that defines the first fluid chamber and the second fluid chamber; a plurality of chokes provided in parallel, which penetrate the partition wall member to connect the first fluid chamber and the second fluid chamber, wherein the chokes comprise chokes of a first group and chokes of a second group both of which generate a damping force that is proportional to a speed of the fluid passing therethrough; a first leaf valve that closes an opening portion of the chokes of the first group opening onto one end of the partition wall member, the first leaf valve comprising a valve body constituted by only a single leaf; and a second leaf valve that closes an opening portion of the chokes of the second group opening onto an opposite side end of the partition wall member, the second leaf valve comprising a valve body constituted by only a single leaf, Wherein a number of chokes of the first group is set at fifty or more, and a number of chokes of the second group is set at fifty or more, and wherein each of the chokes has a circular cross-section with a diameter of no more than 1 mm.
