Abstract
A damping valve includes a valve disc, a ring-shaped leaf valve, and a biasing mechanism. The valve disc includes a passage and a valve seat. The valve seat surrounds an exit end of the passage. The leaf valve is stacked on the valve disc. The leaf valve separates from and is seated on the valve seat to open and close the passage. The biasing mechanism causes a variable biasing force to act on the leaf valve to the valve disc side. The entire leaf valve is configured to axially retreat with respect to the valve disc. A clearance is formed between the leaf valve and the valve seat in a state in which the leaf valve is stacked on the valve disc with no load.
