Claims

[Claims for Utility Model Registration] (1) A compression side oil passage and an extension side oil passage are formed in the piston, and a compression side valve that opens and closes the compression side oil passage and a compression side oil passage that opens and closes the expansion side oil passage are provided on both sides of the piston. In a valve mechanism of a shock absorber equipped with a rebound valve, a sub-oil passage is provided in parallel with the oil passage to bypass the valve, and this sub-oil passage has an oil on the extension-side valve side that opens and closes this sub-oil passage. A valve mechanism for a shock absorber, characterized in that a sub-valve consisting of a disc valve with a hole formed therein and a disc valve valve facing an oil hole of the disc valve is provided, and further a valve seat is interposed between the two disc valves. (2) A shock absorber in which a compression side oil passage and a rebound oil passage are formed in the piston, and a compression side valve that opens and closes the compression side oil passage and a growth side valve that opens and closes the expansion side oil passage are provided on both sides of the piston. In the valve mechanism of the device, a sub-oil passage that bypasses the valve is provided in parallel with the oil passage, and this sub-oil passage includes a disc valve that has an oil hole formed on the compression side valve side to open and close this sub-oil passage, and this sub-oil passage. A valve mechanism for a shock absorber, characterized in that a sub-valve consisting of a disc valve is provided facing an oil hole of the disc valve, and a valve seat is further interposed between the two disc valves.
