Claims

[Scope of utility model registration request]

A case that divides the inside of the cylinder into a first liquid chamber and a second liquid chamber, the passage extending from the first liquid chamber, and a first orifice communicating the passage with the second liquid chamber. and a case having a hollow hole, a spool slidably disposed in the hollow hole of the case, the hollow hole communicating with the passage, a first auxiliary liquid chamber, and the second auxiliary liquid chamber.
a spool that is partitioned into a second auxiliary liquid chamber that communicates with the liquid chamber of the spool and forms a second orifice in the passage in conjunction with the case; a damping valve for a steering damper, the damping valve including a pair of springs biased toward the steering damper;
